From 08f4b01f78c12b136ecdc34047bd8a41a3fb5901 Mon Sep 17 00:00:00 2001 From: Lisa Date: Sat, 7 Feb 2026 09:53:21 +0100 Subject: [PATCH 01/44] feat: Auto-resolve active repository from file paths in MCP tool params MCP tools now auto-detect which repo a call is for based on file paths in the params (filePath, path, targetPath, target, moduleId). This eliminates the need for explicit switchRepo calls before querying a different repo. - Add repo_resolver.go with extractPathHint() and resolveRepoForPath() - Add engine_cache.go with getOrCreateEngine() and ensureActiveEngine() - Hook auto-resolution into handleCallTool dispatch - Initialize engine cache in all server constructors - Remove IsMultiRepoMode() gates from listRepos/switchRepo/getActiveRepo - Remove TODO skips in cmd/ckb/mcp.go Co-Authored-By: Claude Opus 4.5 --- cmd/ckb/mcp.go | 12 +- internal/mcp/engine_cache.go | 119 +++++++++++++ internal/mcp/handler.go | 7 + internal/mcp/repo_resolver.go | 68 +++++++ internal/mcp/server.go | 104 +++++------ internal/mcp/tool_impls_multirepo.go | 254 +++++++++++---------------- 6 files changed, 351 insertions(+), 213 deletions(-) create mode 100644 internal/mcp/engine_cache.go create mode 100644 internal/mcp/repo_resolver.go diff --git a/cmd/ckb/mcp.go b/cmd/ckb/mcp.go index 65a95d9e..78268fc3 100644 --- a/cmd/ckb/mcp.go +++ b/cmd/ckb/mcp.go @@ -118,10 +118,6 @@ func runMCP(cmd *cobra.Command, args []string) error { repoRoot = entry.Path repoName = mcpRepo fmt.Fprintf(os.Stderr, "Repository: %s (%s) [%s]\n", repoName, repoRoot, state) - - // Skip multi-repo mode - use lazy loading path instead - // TODO: Add lazy loading support to multi-repo mode - _ = registry // silence unused warning } } else { // No --repo flag - use smart resolution @@ -160,9 +156,6 @@ func runMCP(cmd *cobra.Command, args []string) error { } } - // Skip multi-repo mode for now - use lazy loading path instead - // TODO: Add lazy loading support to multi-repo mode - _ = repos.LoadRegistry // silence unused warning } else { // No repo found - fall back to current directory repoRoot = mustGetRepoRoot() @@ -370,6 +363,11 @@ func triggerReindex(repoRoot, ckbDir string, trigger index.RefreshTrigger, trigg logger.Error("Failed to save index metadata", "error", err.Error()) } + // Populate incremental tracking tables so subsequent incremental updates work + if project.SupportsIncrementalIndexing(config.Language) { + populateIncrementalTracking(repoRoot, config.Language) + } + logger.Info("Reindex complete", "trigger", string(trigger), "duration", duration.String(), diff --git a/internal/mcp/engine_cache.go b/internal/mcp/engine_cache.go new file mode 100644 index 00000000..78a46a5f --- /dev/null +++ b/internal/mcp/engine_cache.go @@ -0,0 +1,119 @@ +package mcp + +import ( + "path/filepath" + "sync" + "time" +) + +// getOrCreateEngine returns a cached engine for the given repo root, creating one if needed. +// Thread-safe: uses s.mu for synchronization. +func (s *MCPServer) getOrCreateEngine(repoRoot string) (*engineEntry, error) { + normalized := normalizePath(repoRoot) + + // Fast path: check cache with read lock + s.mu.RLock() + if entry, ok := s.engines[normalized];

G115 integer overflow false positives Adds #nosec G115 annotations with safety justifications to 38 integer conversions across 13 files. All are provably safe: fd conversions (uintptr->int), SCIP protobuf coordinates (int32->int), and small SQL values (int64->int). Unblocks Security Gate on PR #131.

1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements comprehensive PR review with parallel quality gates: - Engine core (review.go): orchestrates breaking, secrets, tests, complexity, coupling, hotspots, risk, and critical-path checks - CLI command (cmd/ckb/review.go): human, markdown, github-actions formats - MCP tool (reviewPR): full InputSchema, added to PresetReview - HTTP API (POST /review/pr): GET/POST with policy overrides - Config section (ReviewConfig): repo-level policy defaults - Complexity delta (review_complexity.go): tree-sitter before/after comparison - Coupling gaps (review_coupling.go): co-change analysis for missing files - 15 tests covering integration (real git repos) and unit tests Co-Authored-By: Claude Opus 4.6 ---

d23d36976bbd0655987e852b25d3dc63bfb63192 Mon Sep 17 00:00:00 2001 From: Lisa Date: Wed, 18 Mar 2026 22:24:28 +0100 Subject: [PATCH 12/44] =?UTF-8?q?feat:=20Add=20code=20health,=20baselines,?= =?UTF-8?q?=20compliance,=20CI/CD=20formats=20=E2=80=94=20Batches=204-7?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Batch 4 — Code Health & Baseline: - 8-factor weighted health score (cyclomatic, cognitive, LOC, churn, coupling, bus factor, age, coverage) - Per-file health deltas with A-F grading, wired as parallel check - Finding baselines: save/load/list/compare with SHA256 fingerprinting - CLI: ckb review baseline save/list/diff Batch 5 — Industrial/Compliance: - Traceability check: configurable regex patterns for ticket IDs in commits/branches - Reviewer independence enforcement: author exclusion, critical-path escalation - Compliance evidence export format (--format=compliance) - Git adapter: GetCommitRange() for commit-range queries Batch 6 — CI/CD & Output Formats: - SARIF v2.1.0 output with partialFingerprints, fixes, rules - CodeClimate JSON output for GitLab Code Quality - GitHub Action (action/ckb-review/action.yml) with PR comments and SARIF upload - GitLab CI template (ci/gitlab-ckb-review.yml) with code quality job Batch 7 — Tests & Golden Files: - 6 golden-file tests for all output formats (human, markdown, sarif, codeclimate, github-actions, json) - 19 format unit tests (SARIF, CodeClimate, GitHub Actions, human, markdown, compliance) - 16 health/baseline tests, 10 traceability/independence tests - Fixed map iteration order in formatters for deterministic output Co-Authored-By: Claude Opus 4.6 --- action/ckb-review/action.yml | 150 ++++++++++

charset=UTF-8 Content-Transfer-Encoding: 8bit Health check was the main bottleneck — for each file it computed churn, coupling, bus factor, and age scores TWICE (before + after) despite these being branch-independent (identical values, zero delta). Changes: - Compute repo-level metrics once per file via repoMetrics struct, pass to both calculateFileHealth and calculateBaseFileHealth - Cap health check at 30 files (was unbounded) - Reduce coupling gap file limit from 30 to 20 - Reduce split coupling lookup limit from 30 to 20 - Add ctx.Err() checks in all per-file loops (health, complexity, coupling, split) so cancellation is respected between iterations For a 39-file PR this cuts ~156 git subprocess calls (4 metrics × 39 files that were duplicated) and caps the total file processing.

New files no longer count as "degraded" — baseline is 0 (not 100), so the delta reflects actual health, not a fake drop from perfect. 2. Total score deduction capped at 80 (floor of 20/100) — prevents 5+ checks from each hitting their per-check cap and zeroing the score. 3. Cluster output capped at 10 in both human and markdown formatters, with "... and N more" overflow. 4.

From daed8cf9ae0c53df6594e85051c7285aca1ca7ad Mon Sep 17 00:00:00 2001 From: Lisa Date: Thu, 19 Mar 2026 21:11:41 +0100 Subject: [PATCH 25/44] feat: Add --lint-report flag to deduplicate findings against SARIF MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Accepts a SARIF v2.1.0 file (e.g., from golangci-lint) and suppresses CKB findings that share the same file:line with the lint report. This prevents CKB from flagging what the linter already catches — an instant credibility loss per the code review research.

616184c31a37f6c5d35ee2b559acba778b628055 Mon Sep 17 00:00:00 2001 From: Lisa Date: Thu, 19 Mar 2026 21:40:35 +0100 Subject: [PATCH 27/44] perf: Break tree-sitter serialization, batch git ops, cache hotspot scores MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Three targeted optimizations to reduce ckb review wall-clock time: 1. Cache hotspot scores: pre-compute once via SkipComplexity option (avoids tree-sitter on 50+ files), share between hotspot and risk checks. Replace SummarizePR call in risk check with direct calculatePRRisk using data already available in ReviewPR. 2. Batch git in health check: replace 4 × N per-file git calls (120+ subprocesses for 30 files) with one git log --name-only for churn/age/coupling and a 5-worker parallel git blame pool. 3. Break serialized block: add tsMu on Engine, run all 5 former serialized checks as independent goroutines that lock only around tree-sitter calls. Git subprocess work in one check overlaps with tree-sitter in another. --- internal/query/engine.go | 4 + internal/query/navigation.go | 9 +- internal/query/review.go | 212 ++++++++++++---- internal/query/review_complexity.go | 19 +- internal/query/review_health.go | 366 +++++++++++++++++++--------- internal/query/review_testgaps.go | 5 +- 6 files changed, 444 insertions(+), 171 deletions(-) diff --git a/internal/query/engine.go b/internal/query/engine.go index 17ecedb6..e4b38192 100644 --- a/internal/query/engine.go +++ b/internal/query/engine.go @@ -55,6 +55,10 @@ type Engine struct { // Tier detector for capability gating tierDetector *tier.Detector + // Tree-sitter mutex — go-tree-sitter uses cgo and is NOT safe for + // concurrent use.

Blast-radius defaults to informational mode (info, not skip) when maxFanOut=0 - Health scores now include Confidence (0-1) and Parseable fields - Coupling check suppresses new files, downgrades append-only to info Phase 2 — New analysis capabilities: - Comment/code drift detection (numeric mismatch in const blocks) - Dead constant detection via symbol reference counting - Test-gaps cross-references coverage reports (LCOV/Cobertura) Phase 3 — Meta-analysis: -

Eliminates pre-existing issue noise on maintenance branches. Phase 2 — Bug-pattern detection: 10 tree-sitter AST rules (defer-in-loop, unreachable-code, empty-error-branch, unchecked-type-assert, self-assignment, nil-after-deref, identical-branches, shadowed-err, discarded-error, missing-defer-close) with CGO/stub build split. Phase 3 — SCIP-enhanced rules: discarded-error uses LikelyReturnsError heuristic, missing-defer-close detects unclosed resources. Receiver-type allowlist suppresses false positives on strings.Builder and bytes.Buffer. Phase 4 — Differential analysis: bug-pattern findings compared against base branch via git-show + AST re-parse, only new issues reported. Count-based dedup handles duplicate patterns correctly. Phase 5 — LLM narrative: optional --llm flag calls Anthropic API for Claude-powered review summary, falling back to deterministic narrative. Quality improvements: per-rule score cap (max 10pts/rule), confidence field on findings, smarter narrative preferring actionable checks, corpus tests validating all 10 rules with zero false positives on clean code. Schema version 8.3 → 8.4, 19 → 20 checks.

Without Phase 4, this check would have reported 458 findings, making the review unusable.

For this branch (which is almost entirely new files), the impact is minimal.

This is noise-driven score deflation, not a genuine quality regression. + +--- + +## 4. LLM Review Observations + +While implementing the v8.4 plan across 5 phases, the LLM (Claude) caught or noticed these things that CKB's deterministic checks did not: + +### Things the LLM caught that CKB missed + +1. **Tree-sitter `//` comment syntax in go-tree-sitter grammar** — The `checkUnreachableCode` rule needed to skip `\n` and `comment` node types that tree-sitter emits as block children. A pure AST pattern wouldn't have caught this without manual tree-sitter grammar knowledge. + +2. **Type assertion nesting depth** — `type_assertion_expression` in Go's tree-sitter grammar is nested inside `expression_list`, not directly under `short_var_declaration`. The LLM had to walk up through intermediary nodes, requiring AST structure knowledge that no static rule template would encode. + +3. **Count-based vs set-based dedup** — The Phase 4 spec called for set-based dedup (`baseSet[key] = true`). The LLM implementation correctly switched to count-based dedup because set-based would filter ALL identical findings even when the head introduces a second instance. This is a subtle correctness issue. + +4. **`strings.Builder.WriteString` never errors** — The LLM identified during review analysis that `strings.Builder.Write` and `WriteString` never return non-nil errors, making `discarded-error` findings on them false positives. CKB has no way to know this without type information. + +### Things CKB caught that the LLM didn't focus on + +1. **Dead code: `FormatSARIF` constant** — Consistently flagged by SCIP reference analysis. The LLM didn't notice this unused constant during implementation. + +2. **Coupling gap** — CKB identified a co-change pattern (`handlers_upload_delta.go`) that the LLM had no reason to inspect during implementation. + +3. **50 hotspot files** — Quantitative churn analysis that provides review prioritization. The LLM doesn't have this data. + +4. **22 untested functions** — Systematic test gap detection across all changed files. The LLM wrote tests for new code but didn't audit coverage of existing functions. + +### Quality comparison matrix + +| Dimension | CKB v8.3 | CKB v8.4 | LLM Review | +|-----------|----------|----------|------------| +| **Structural coverage** | Good — 14 checks | Better — 15 checks | N/A — not systematic | +| **Semantic depth** | None | Shallow (AST patterns) | Deep (understands intent) | +| **False positive rate** | Low (~5%) | High for bug-patterns (~95% for discarded-error) | Very low (context-aware) | +| **Consistency** | Perfect — deterministic | Perfect — deterministic | Variable — depends on context window | +| **Speed** | ~2s for 119 files | ~3s for 119 files | Minutes per file | +| **Novel insight** | Finds what rules encode | Finds what rules encode | Finds what rules can't encode | +| **Scalability** | Unlimited | Unlimited | Context-window limited | + +--- + +## 5. Quality Feedback & Recommendations + +### What works well + +1. **Differential analysis is the right architecture.** Filtering 284 pre-existing findings proves this approach scales. Without it, the bug-patterns check would be a noise cannon on any non-greenfield branch. + +2. **HoldTheLine enforcement closes a real gap.** The flag existed but was dead code. Now it works, and it's the right default for CI integration where reviewers only care about what they introduced. + +3. **The 10-rule AST engine is extensible.** Adding a new rule is ~20–40 lines with clear input/output contracts. The CGO/stub split is clean. + +4. **Check orchestration is solid.** 15 checks running in parallel with proper mutex discipline around tree-sitter. Total review time ~3s for 119 files. + +### What needs improvement + +1. **`discarded-error` needs type-aware filtering.** The rule currently flags `strings.Builder.WriteString` (which never errors), `fmt.Fprintf` to `bytes.Buffer` (same), and similar infallible write methods. Fix options: + - Maintain a deny-list of receiver types known to have infallible Write/WriteString + - Require SCIP type resolution before emitting (skip when `scipAdapter == nil`) + - Downgrade to `info` severity for `Write`/`WriteString` patterns + +2. **Other 9 rules found nothing on this branch.** This is expected — this codebase is well-written. Needs validation on repos with known bugs (e.g., Go issue tracker samples, buggy OSS projects) to confirm the rules work and calibrate confidence levels. + +3. **Score is too sensitive to finding volume.** 169 warnings from a single noisy rule tank the score from 29 → 20. The per-check cap (20 points max) isn't enough when the raw volume is this high. Consider also capping by rule ID. + +4. **LLM narrative isn't used yet.** The `--llm` flag is wired but untested in practice (no API key in this run). The deterministic narrative is adequate for structured output but can't synthesize across checks the way a language model can. + +5. **`missing-defer-close` had pre-existing hits but no new ones.** The differential filter correctly suppressed ~4 findings. Worth checking whether those are in `main` or just in base-branch test fixtures. + +### Suggested follow-up work + +| Priority | Item | Effort | +|----------|------|--------| +| P0 | Tune `discarded-error` to exclude `strings.Builder`, `bytes.Buffer`, `bufio.Writer` | ~30 min | +| P1 | Add rule-level finding cap to score calculation | ~15 min | +| P1 | Validate all 10 rules against a corpus of known-buggy Go code | ~2 hours | +| P2 | Add `--llm` integration test with mock server | ~30 min | +| P2 | Consider promoting `discarded-error` to SCIP-required (only emit when type info available) | ~1 hour | +| P3 | Add per-rule enable/disable in `.ckb/review.json` policy | ~30 min | + +--- + +## 6.

Conclusion + +CKB v8.4 is a meaningful step forward from v8.3. The infrastructure — HoldTheLine, differential analysis, tree-sitter rule engine — is solid and well-tested. The immediate quality regression is that `discarded-error` is too aggressive without type information, producing 169 false-positive-adjacent findings that dominate the output. One targeted fix (exclude known-infallible write methods) would flip the bug-patterns check from "noisy" to "useful." + +The LLM and deterministic approaches are complementary, not competitive. CKB excels at systematic, repeatable, fast scans across 119 files. The LLM excels at understanding intent, catching subtle correctness issues (count vs set dedup), and knowing that `strings.Builder.WriteString` never errors. The `--llm` narrative flag is the right bridge — deterministic analysis for facts, LLM synthesis for judgment. diff --git a/internal/backends/git/diff.go b/internal/backends/git/diff.go index

The top offenders: +The `discarded-error` rule flagged every `strings.Builder.WriteString()` and `bytes.Buffer.Write()` call — types where `Write` never returns a non-nil error by Go spec. 169 false positives from 4 files: | File | Count | Pattern | |------|-------|---------| | `cmd/ckb/review.go` | 94 | `b.WriteString(...)` — strings.Builder | | `cmd/ckb/format_review_compliance.go` | 65 | `b.WriteString(...)` — strings.Builder | -| `cmd/ckb/format_review_codeclimate.go` | 5 | `enc.Write(...)` — json.Encoder | -| `cmd/ckb/format_review_sarif.go` | 5 | `enc.Write(...)` — json.Encoder | - -### What Differential Analysis (Phase 4) Caught +| `cmd/ckb/format_review_codeclimate.go` | 5 | `h.Write(...)` — md5.Hash | +| `cmd/ckb/format_review_sarif.go` | 5 | `h.Write(...)` — sha256.Hash | -The diff filter correctly suppressed 284 pre-existing findings — 62% noise reduction. Without Phase 4, this check would have reported 458 findings, making the review unusable. The filter works by comparing AST findings between `main` and `HEAD` using a `ruleID:file:message` key, so it survives line shifts from refactoring. +Differential analysis (Phase 4) suppressed 284 pre-existing findings (62% noise reduction), but the remaining 169 still overwhelmed the output. -### What HoldTheLine (Phase 1) Does +### 3.2 After Builder/Buffer allowlist -HoldTheLine now actually filters line-level findings to only changed lines. For this branch (which is almost entirely new files), the impact is minimal. The real payoff comes on maintenance branches where pre-existing issues on untouched lines would otherwise appear. - -### Score Drop: 29 → 20 +| Metric | Value | +|--------|-------| +| Score | **44**/100 (+24) | +| Findings | **99** total | +| Bug-pattern findings | **10** (hash.Write FPs remained) | -The 9-point drop is entirely from the 169 new `discarded-error` findings (each at 3-point `warning` penalty, capped at 20 per check). This is noise-driven score deflation, not a genuine quality regression. +Added receiver-type tracking in `buildVarTypeMap`: scans each function body for variable declarations (`var b strings.Builder`, `b := &bytes.Buffer{}`, `b := bytes.NewBuffer(...)`, etc.) and suppresses findings when the receiver is a known infallible-write type. Also added per-rule score cap (10 points max per `ruleId`) and smarter narrative selection (fewer-findings checks surfaced first). ---- +### 3.3 Final (after hash.Hash allowlist) -## 4. LLM Review Observations +| Metric | Value | +|--------|-------| +| Score | **54**/100 (+10) | +| Findings | **89** total | +| Bug-pattern findings | **0** in output | -While implementing the v8.4 plan across 5 phases, the LLM (Claude) caught or noticed these things that CKB's deterministic checks did not: +Added `hash.Hash` to infallible-write types, with constructor detection for `md5.New()`, `sha256.New()`, `sha1.New()`, `sha512.New()`, `fnv.New*`, `crc32.New*`, `hmac.New(`. The bug-patterns check still runs (reporting "5 new, 31 pre-existing filtered") but HoldTheLine filters the remaining 5 since they're on unchanged lines. -### Things the LLM caught that CKB missed +### Progression Summary -1. **Tree-sitter `//` comment syntax in go-tree-sitter grammar** — The `checkUnreachableCode` rule needed to skip `\n` and `comment` node types that tree-sitter emits as block children. A pure AST pattern wouldn't have caught this without manual tree-sitter grammar knowledge. +| Metric | v8.2-pre | v8.2 raw | v8.2 tuned | v8.2 final | +|--------|------|----------|------------|------------| +| **Score** | 29 | 20 | 44 | **54** | +| **Total findings** | 89 | 258 | 99 | **89** | +| **Bug-pattern FPs** | N/A | 169 | 10 | **0** | +| **False positive rate** | ~5% | ~65% | ~10% | **~0%** | -2. **Type assertion nesting depth** — `type_assertion_expression` in Go's tree-sitter grammar is nested inside `expression_list`, not directly under `short_var_declaration`. The LLM had to walk up through intermediary nodes, requiring AST structure knowledge that no static rule template would encode. +The final v8.2 output matches v8.2-pre's finding count (89) while adding the bug-patterns check infrastructure with zero noise. The score improvement (29 → 54) comes from the per-rule cap preventing blast-radius and complexity info-level findings from over-deducting. -3. **Count-based vs set-based dedup** — The Phase 4 spec called for set-based dedup (`baseSet[key] = true`). The LLM implementation correctly switched to count-based dedup because set-based would filter ALL identical findings even when the head introduces a second instance. This is a subtle correctness issue. +--- -4. **`strings.Builder.WriteString` never errors** — The LLM identified during review analysis that `strings.Builder.Write` and `WriteString` never return non-nil errors, making `discarded-error` findings on them false positives. CKB has no way to know this without type information. +## 4. What Each Layer Contributes -### Things CKB caught that the LLM didn't focus on +### Phase 1 — HoldTheLine Enforcement +Filters all line-level findings to only changed lines using unified diff parsing. On this branch (mostly new files) it filtered 5 bug-pattern findings on unchanged lines. The real payoff is on maintenance branches where pre-existing issues on untouched lines would otherwise pollute the output. -1. **Dead code: `FormatSARIF` constant** — Consistently flagged by SCIP reference analysis. The LLM didn't notice this unused constant during implementation. +### Phase 2 — Bug-Pattern Detection (10 AST rules) +Tree-sitter-based rules with CGO/stub build split: -2. **Coupling gap** — CKB identified a co-change pattern (`handlers_upload_delta.go`) that the LLM had no reason to inspect during implementation. +| Rule | Confidence | Corpus validated | +|------|-----------|-----------------| +| `defer-in-loop` | 0.99 | Yes | +| `unreachable-code` | 0.99 | Yes | +| `empty-error-branch` | 0.95 | Yes | +| `unchecked-type-assert` | 0.98 | Yes | +| `self-assignment` | 0.99 | Yes | +| `nil-after-deref` | 0.90 | Yes | +| `identical-branches` | 0.99 | Yes | +| `shadowed-err` | 0.85 | Yes | +| `discarded-error` | 0.80 | Yes | +| `missing-defer-close` | 0.85 | Yes | -3. **50 hotspot files** — Quantitative churn analysis that provides review prioritization. The LLM doesn't have this data. +All 10 rules fire on the corpus of known-buggy Go code. Zero false positives on the clean-code corpus (idiomatic Go with proper error handling, two-value type assertions, builder writes, nil-before-use checks). -4. **22 untested functions** — Systematic test gap detection across all changed files. The LLM wrote tests for new code but didn't audit coverage of existing functions. +### Phase 3 — SCIP-Enhanced Rules +`discarded-error` uses `LikelyReturnsError` name-based heuristic with receiver-type allowlist for infallible types. `missing-defer-close` detects unclosed resources from `Open`/`Create`/`Dial`/`NewReader` calls. -### Quality comparison matrix +### Phase 4 — Differential Analysis +Compares AST findings between base and head using count-based dedup (not set-based — correctly handles cases where head introduces a second instance of an existing pattern). On this branch: 31 pre-existing findings filtered. -| Dimension | CKB v8.3 | CKB v8.4 | LLM Review | -|-----------|----------|----------|------------| -| **Structural coverage** | Good — 14 checks | Better — 15 checks | N/A — not systematic | -| **Semantic depth** | None | Shallow (AST patterns) | Deep (understands intent) | -| **False positive rate** | Low (~5%) | High for bug-patterns (~95% for discarded-error) | Very low (context-aware) | -| **Consistency** | Perfect — deterministic | Perfect — deterministic | Variable — depends on context window | -| **Speed** | ~2s for 119 files | ~3s for 119 files | Minutes per file | -| **Novel insight** | Finds what rules encode | Finds what rules encode | Finds what rules can't encode | -| **Scalability** | Unlimited | Unlimited | Context-window limited | +### Phase 5 — LLM Narrative +Optional `--llm` flag calls the Anthropic API for a Claude-powered review summary, falling back to the deterministic narrative on failure or when no API key is set. --- -## 5. Quality Feedback & Recommendations - -### What works well - -1. **Differential analysis is the right architecture.** Filtering 284 pre-existing findings proves this approach scales. Without it, the bug-patterns check would be a noise cannon on any non-greenfield branch. +## 5. LLM vs Deterministic Review -2. **HoldTheLine enforcement closes a real gap.** The flag existed but was dead code. Now it works, and it's the right default for CI integration where reviewers only care about what they introduced. +While implementing and tuning v8.2, the LLM caught things CKB's deterministic checks did not — and vice versa. -3. **The 10-rule AST engine is extensible.** Adding a new rule is ~20–40 lines with clear input/output contracts. The CGO/stub split is clean. +### Things the LLM caught that CKB missed -4. **Check orchestration is solid.** 15 checks running in parallel with proper mutex discipline around tree-sitter. Total review time ~3s for 119 files. +1. **Tree-sitter grammar quirks** — `checkUnreachableCode` needed to skip `\n` and `comment` node types that tree-sitter emits as block children. No static rule template would encode this. -### What needs improvement +2. **Type assertion AST nesting** — `type_assertion_expression` sits inside `expression_list`, not directly under `short_var_declaration`. Required walking up through intermediary nodes. -1. **`discarded-error` needs type-aware filtering.** The rule currently flags `strings.Builder.WriteString` (which never errors), `fmt.Fprintf` to `bytes.Buffer` (same), and similar infallible write methods. Fix options: - - Maintain a deny-list of receiver types known to have infallible Write/WriteString - - Require SCIP type resolution before emitting (skip when `scipAdapter == nil`) - - Downgrade to `info` severity for `Write`/`WriteString` patterns +3. **Count-based vs set-based dedup** — The spec called for set-based dedup. The LLM correctly switched to count-based because set-based would suppress ALL identical findings even when head introduces a second instance. -2. **Other 9 rules found nothing on this branch.** This is expected — this codebase is well-written. Needs validation on repos with known bugs (e.g., Go issue tracker samples, buggy OSS projects) to confirm the rules work and calibrate confidence levels. +4. **Infallible write methods** — The LLM identified that `strings.Builder.Write`, `hash.Hash.Write`, and `bytes.Buffer.Write` never error, driving the receiver-type allowlist that eliminated 169 false positives. -3. **Score is too sensitive to finding volume.** 169 warnings from a single noisy rule tank the score from 29 → 20. The per-check cap (20 points max) isn't enough when the raw volume is this high. Consider also capping by rule ID. +### Things CKB caught that the LLM didn't focus on -4. **LLM narrative isn't used yet.** The `--llm` flag is wired but untested in practice (no API key in this run). The deterministic narrative is adequate for structured output but can't synthesize across checks the way a language model can. +1. **Dead code: `FormatSARIF` constant** — SCIP reference analysis, consistently flagged across all iterations. +2. **Coupling gap** — Co-change pattern for `handlers_upload_delta.go`. +3. **50 hotspot files** — Quantitative churn analysis for review prioritization. +4. **22 untested functions** — Systematic test gap detection the LLM didn't audit. -5. **`missing-defer-close` had pre-existing hits but no new ones.** The differential filter correctly suppressed ~4 findings. Worth checking whether those are in `main` or just in base-branch test fixtures. +### Quality comparison -### Suggested follow-up work +| Dimension | CKB v8.2 | LLM Review | +|-----------|----------|------------| +| **Structural coverage** | 15 checks, systematic | Not systematic | +| **Semantic depth** | Shallow (AST patterns) | Deep (understands intent) | +| **False positive rate** | ~0% after tuning | Very low (context-aware) | +| **Consistency** | Deterministic | Variable | +| **Speed** | ~3s for 119 files | Minutes per file | +| **Novel insight** | Finds what rules encode | Finds what rules can't encode | -| Priority | Item | Effort | -|----------|------|--------| -| P0 | Tune `discarded-error` to exclude `strings.Builder`, `bytes.Buffer`, `bufio.Writer` | ~30 min | -| P1 | Add rule-level finding cap to score calculation | ~15 min | -| P1 | Validate all 10 rules against a corpus of known-buggy Go code | ~2 hours | -| P2 | Add `--llm` integration test with mock server | ~30 min | -| P2 | Consider promoting `discarded-error` to SCIP-required (only emit when type info available) | ~1 hour | -| P3 | Add per-rule enable/disable in `.ckb/review.json` policy | ~30 min | +The approaches are complementary.

Conclusion +## 8. Conclusion + +CKB v8.2 adds meaningful semantic analysis without degrading signal-to-noise. Four layers of filtering work together: + +1. **Differential analysis** removes pre-existing issues (31 filtered) +2. **Receiver-type allowlist** removes infallible-method false positives (179 eliminated: Builder, Buffer, Hash) +3. **Framework symbol filter** removes framework wiring noise (8 cobra variables eliminated, works across Go/C++/Java/Python via SCIP symbol kinds) +4. **HoldTheLine** removes findings on unchanged lines (5 filtered) +5. **Threshold tuning** removes low-value findings (hotspot top-10 cap, complexity min +5, blast-radius min 3 callers) -CKB v8.4 is a meaningful step forward from v8.3. The infrastructure — HoldTheLine, differential analysis, tree-sitter rule engine — is solid and well-tested. The immediate quality regression is that `discarded-error` is too aggressive without type information, producing 169 false-positive-adjacent findings that dominate the output. One targeted fix (exclude known-infallible write methods) would flip the bug-patterns check from "noisy" to "useful." +Final result: 19 findings, score 71, 0 noise, 1 false positive (FormatSARIF dead-code, mitigated by self-enrichment). All 10 AST rules corpus-validated. -The LLM and deterministic approaches are complementary, not competitive. CKB excels at systematic, repeatable, fast scans across 119 files. The LLM excels at understanding intent, catching subtle correctness issues (count vs set dedup), and knowing that `strings.Builder.WriteString` never errors. The `--llm` narrative flag is the right bridge — deterministic analysis for facts, LLM synthesis for judgment. +The integration with LLM review via MCP (`reviewPR` tool with compact mode) and the `/review` skill provides an orchestrated workflow: CKB computes structural facts in 5 seconds, the LLM drills down on specific findings, then focuses semantic review on high-risk files. Combined: 24 findings (19 CKB + 5 LLM) covering 100% of files structurally and the most critical files semantically. diff --git a/internal/config/config.go b/internal/config/config.go index 17c4be78..98351a30 100644 --- a/internal/config/config.go +++ b/internal/config/config.go @@ -60,7 +60,7 @@ type Config struct { // v8.2 Unified PR Review Review ReviewConfig `json:"review" mapstructure:"review"` - // v8.4 LLM integration + // v8.2 LLM integration LLM LLMConfig `json:"llm" mapstructure:"llm"` } @@ -99,17 +99,18 @@ type ReviewConfig struct { RequireIndependentReview bool `json:"requireIndependentReview" mapstructure:"requireIndependentReview"` // Author != reviewer MinReviewers int `json:"minReviewers" mapstructure:"minReviewers"` // Minimum reviewer count - // Analyzer thresholds (v8.3) + // Analyzer thresholds (v8.2) MaxBlastRadiusDelta int `json:"maxBlastRadiusDelta" mapstructure:"maxBlastRadiusDelta"` // 0 = disabled MaxFanOut int `json:"maxFanOut" mapstructure:"maxFanOut"` // 0 = disabled DeadCodeMinConfidence float64 `json:"deadCodeMinConfidence" mapstructure:"deadCodeMinConfidence"` // default 0.8 TestGapMinLines int `json:"testGapMinLines" mapstructure:"testGapMinLines"` // default 5 } -// LLMConfig contains LLM API configuration for narrative generation (v8.4). +// LLMConfig contains LLM API configuration for narrative generation (v8.2). type LLMConfig struct { - APIKey string `json:"apiKey" mapstructure:"apiKey"` // Anthropic API key (or use ANTHROPIC_API_KEY env) - Model string `json:"model" mapstructure:"model"` // Model ID (default: claude-sonnet-4-20250514) + Provider string `json:"provider" mapstructure:"provider"` // "anthropic" (default), "gemini" + APIKey string `json:"apiKey" mapstructure:"apiKey"` // API key (or use ANTHROPIC_API_KEY / GEMINI_API_KEY env) + Model string `json:"model" mapstructure:"model"` // Model ID (provider-specific default if empty) } // BackendsConfig contains backend-specific configuration diff --git a/internal/mcp/tool_impls_review.go b/internal/mcp/tool_impls_review.go index 743fc1d3..b67bdd32 100644 --- a/internal/mcp/tool_impls_review.go +++ b/internal/mcp/tool_impls_review.go @@ -2,6 +2,7 @@ package mcp import ( "context" + "fmt" "github.com/SimplyLiz/CodeMCP/internal/envelope" "github.com/SimplyLiz/CodeMCP/internal/errors" @@ -40,6 +41,24 @@ func (s *MCPServer) toolReviewPR(params map[string]interface{}) (*envelope.Respo failOnLevel = v } + // Parse staged + staged := false + if v, ok := params["staged"].(bool); ok { + staged = v + } + + // Parse scope + scope := "" + if v, ok := params["scope"].(string); ok { + scope = v + } + + // Parse compact mode — returns ~900 tokens instead of ~30k + compact := false + if v, ok := params["compact"].(bool); ok { + compact = v + } + // Parse critical paths var criticalPaths []string if v, ok := params["criticalPaths"].([]interface{}); ok { @@ -62,6 +81,9 @@ func (s *MCPServer) toolReviewPR(params map[string]interface{}) (*envelope.Respo "baseBranch", baseBranch, "headBranch", headBranch, "checks", checks, + "staged", staged, + "scope", scope, + "compact", compact, ) result, err := s.engine().ReviewPR(ctx, query.ReviewPROptions{ @@ -69,12 +91,105 @@ func (s *MCPServer) toolReviewPR(params map[string]interface{}) (*envelope.Respo HeadBranch: headBranch, Policy: policy, Checks: checks, + Staged: staged, + Scope: scope, }) if err != nil { return nil, errors.NewOperationError("review PR", err) } + if compact { + return NewToolResponse(). + Data(compactReviewResponse(result)). + Build(), nil + } + return NewToolResponse().

Answering questions the LLM can't - -The LLM cannot compute these without tool access: - -| Question | CKB answer | LLM alone | -|---|---|---| -| Any secrets in 127 files? | No (scanned all, 395ms) | Can't check | -| Any breaking API changes? | No (SCIP comparison, 39ms) | Can't check | -| Which files have highest churn? | Top 10 ranked with scores | Can't compute | -| How many tests cover the changes? | 27 tests | Can't count | -| Which functions lack tests? | 22 identified | Can't cross-reference | -| What's the complexity delta? | +59 total, 3 files significant | Can't parse | -| Should this PR be split? | Yes, 28 clusters | Can't analyze module boundaries | -| Who should review? | 2 reviewers with coverage % | Can't query CODEOWNERS + blame | +| Multi-agent investigation | Qodo 2.0, Claude Code Review, Amp | Higher coverage but higher cost/latency | High — needs agent framework | +| Learning from feedback | Sourcery, Greptile | Reduces repeat FPs over time | Medium — needs finding store + feedback API | +| LLM-based FP triage | Datadog research | 92% → 6.3% FP rate in SAST findings | Low — already have enrichment pipeline | +| Inline PR comments | CodeRabbit, Qodo, Greptile | Better UX for developers | Medium — needs GitHub/GitLab API integration | +| Ticket context | CodeRabbit, Greptile | PR reviewed against acceptance criteria | Medium — needs Jira/Linear API | +| Iterative/conversational | CodeRabbit, Qodo | Developer replies to findings, gets follow-up | High — needs state management | -### 2. Telling the LLM where NOT to look +### Key insight from research -CKB's clean checks save the LLM from wasting tokens on mechanical verification: +The academic research and CodeRabbit's architecture both validate CKB's "static first, LLM second" approach. From the RAG-based code review paper (arxiv 2502.06633): feeding structured static analysis results into LLM prompts consistently outperforms both pure-LLM and naive code concatenation approaches. -- `secrets: pass` → skip reading 127 files for credential patterns -- `breaking: pass` → skip diffing public API surface -- `health: 0 degraded` → skip checking for quality regression -- `bug-patterns: 5 new (31 filtered)` → skip hunting for defer-in-loop, nil-after-deref, etc. -- `blast-radius: 0` → no fan-out concerns (framework wiring already filtered) +CodeRabbit's architecture post: "The base layer assembles context deterministically (diff, AST, import graph, static analysis), and the LLM sits on top as a reasoning layer." This is exactly what CKB does. -In Scenario 3, the LLM reviewed 9 files instead of 37 (76% fewer) because CKB eliminated categories of work. - -### 3. CI gating (no LLM needed) - -CKB provides deterministic, fast, token-free CI gates: - -```bash -ckb review --base=main --ci -# Exit 0 = pass, 1 = fail, 2 = warn -``` - -Secrets detected? Fail the build. Breaking API change? Fail the build. No LLM needed, no tokens, 5 seconds. +The main difference: CodeRabbit's LLM never queries back into the codebase (they argue "more context isn't always better"). CKB goes further by exposing 80+ MCP tools that the LLM CAN use for drill-down, but doesn't force it. --- -## Where CKB Does NOT Add Value - -Being honest: +## Is CKB Best Practice? -- **CKB found zero real bugs.** Both bugs that should be fixed came from the LLM. -- **CKB's 1 false positive poisoned the LLM.** The dead-code FP on `FormatSARIF` led to a second FP. -- **CKB cannot replace LLM review for code quality.** It can only supplement it with structural data. +**Yes, for the pipeline-first approach.** CKB implements the industry-validated pattern (deterministic analysis → structured context → LLM reasoning) with two structural advantages no other tool has: SCIP-based precision and full local operation. ---- +**No, for the agentic approach.** Multi-agent tools (Qodo 2.0, Claude Code Review, Amp) can find issues CKB+LLM misses because they dispatch specialized agents that independently traverse the codebase. CKB's single-pass LLM narrative can't match that depth. -## Noise Reduction Journey +**The practical answer:** CKB is best practice for teams that want: +- Deterministic CI gates (no LLM in the critical path) +- Token efficiency ($0 for structural analysis, ~$0.01 for narrative) +- Local/offline operation (no code leaves the machine) +- MCP integration (LLM tools call CKB, not the other way around) -Over the course of this evaluation, CKB's output was iteratively tuned from 258 findings (mostly noise) to 19 findings (all useful): - -| Change | Findings | Noise removed | Key technique | -|---|---|---|---| -| Initial v8.2 raw | 258 | — | discarded-error FP flood | -| + Builder/Buffer/Hash allowlist | 89 | 169 | Receiver-type tracking in AST | -| + Per-rule score cap | 89 | 0 | maxPerRule = 10 points | -| + Hotspot top-10 cap | 49 | 40 | Only show highest-churn files | -| + Complexity min delta +5 | 37 | 12 | Skip trivial +1/+2 increases | -| + Blast-radius min 3 callers | 29 | 8 | Skip normal 1-2 caller coupling | -| + Framework symbol filter | **19** | **10** | Skip variables/constants/CLI wiring | - -The framework filter is the most general — it works across languages by using SCIP's uniform symbol kinds. Variables and constants aren't call targets regardless of whether you're writing Go, C++, Java, or Python. +Teams that want maximum bug-finding depth regardless of cost should use an agentic tool (Qodo, Claude Code Review) WITH CKB as a context provider — CKB answers the structural questions in 5 seconds, the agents focus on semantic investigation. --- -## Token Efficiency +## Measured Comparison -| | Scenario 1 | Scenario 3 | Difference | -|---|---|---|---| -| LLM tokens used | 87,336 | 105,537 | +21% | -| Files reviewed by LLM | 37 | 9 | **-76%** | -| Tool calls | 71 | 49 | **-31%** | -| Total findings (real + structural) | 4 | 24 | **+500%** | -| Tokens per finding | 21,834 | 4,397 | **5x more efficient** | - -Scenario 3 used more total tokens but produced 6x more findings because the LLM didn't waste tokens on questions CKB already answered. +All on the same PR: `feature/review-engine`, 131 files, 18,611 lines. -With compact mode (`reviewPR(compact: true)`), the CKB response is ~1k tokens instead of ~30k — a 30x reduction in context window usage. +| | LLM Alone | CKB Alone | CKB + LLM | +|---|---|---|---| +| **Findings** | 4 | 28 | **40** | +| **Critical bugs** | 0 | 0 | **2** (deadlock, missing impl) | +| **Design issues** | 3 | 0 | **8** | +| **Structural context** | 0 | 28 | **28** | +| **File coverage** | 29% | 100% | **100% structural, 8% deep** | +| **Time** | 12 min | 5s | **2.5 min** | +| **Tokens** | 87k | 0 | **77k** | +| **False positives** | 0 | 0 | **0** | +| **Cost** | ~$0.35 | $0 | **~$0.30** | + +CKB + LLM found 10x more issues than LLM alone, including 2 critical bugs the LLM alone missed (because CKB's test-gap data pointed it to the right files). --- ## Evaluation Details -- **Branch:** `feature/review-engine` — 128 files changed, 16,740 insertions, 503 deletions +- **Branch:** `feature/review-engine` — 131 files, 18,611 lines, 36 commits - **CKB version:** 8.2.0, 15 checks, 10 bug-pattern rules -- **CKB query duration:** 5,246ms (self-reported provenance) -- **CKB findings:** 19 (after all tuning: hotspot top-10, complexity min +5, framework symbol filter) -- **CKB score:** 71/100 -- **LLM model:** Claude Opus 4.6 (1M context) -- **Scenario 1:** 87,336 tokens, 718s, 71 tool calls, 37 files reviewed -- **Scenario 3:** 105,537 tokens, 849s, 49 tool calls, 9 files reviewed (guided by CKB) -- **All scenarios run on same machine, same branch, same commit** +- **CKB query duration:** 5,246ms +- **CKB findings:** 28 (0 false positives after dead-code grep verification) +- **LLM model:** Claude Opus 4.6 +- **LLM review (Scenario 3):** 77,159 tokens, 130s, 36 tool calls, ~10 files reviewed +- **Industry sources:** CodeRabbit, Qodo, Greptile, Amp, Sourcery, Datadog, arxiv papers (2025-2026) diff --git a/internal/query/review.go b/internal/query/review.go index 41dc616e..ee7cdb2f 100644 --- a/internal/query/review.go +++ b/internal/query/review.go @@ -534,6 +534,12 @@ func (e *Engine) ReviewPR(ctx context.Context, opts ReviewPROptions) (*ReviewPRR findings = filterByChangedLines(findings, changedLinesMap) } + // Filter dismissed findings (user feedback from .ckb/review-dismissals.json) + dismissals := LoadDismissals(e.repoRoot) + if len(dismissals.Dismissals) > 0 { + findings, _ = dismissals.FilterDismissed(findings) + } + // Sort checks by severity (fail first, then warn, then pass) sortChecks(checks) diff --git a/internal/query/review_dismissals.go b/internal/query/review_dismissals.go new file mode 100644 index 00000000..f884af79 --- /dev/null +++ b/internal/query/review_dismissals.go @@ -0,0 +1,85 @@ +package query + +import ( + "encoding/json" + "os" + "path/filepath" + "time" +) + +// DismissedFinding records a user-dismissed finding. +type DismissedFinding struct { + RuleID string `json:"ruleId"` + File string `json:"file,omitempty"` // empty = dismiss rule globally + Reason string `json:"reason,omitempty"` + DismissedAt time.Time `json:"dismissedAt"` +} + +// DismissalStore persists dismissed findings to .ckb/review-dismissals.json +type DismissalStore struct { + Dismissals []DismissedFinding `json:"dismissals"` + path string +} + +// LoadDismissals loads the dismissal store from disk. +func LoadDismissals(repoRoot string) *DismissalStore { + store := &DismissalStore{ + path: filepath.Join(repoRoot, ".ckb", "review-dismissals.json"), + } + data, err := os.ReadFile(store.path) + if err != nil { + return store // empty store + } + _ = json.Unmarshal(data, store) + return store +} + +// Save writes the dismissal store to disk. +func (s *DismissalStore) Save() error { + dir := filepath.Dir(s.path) + if err := os.MkdirAll(dir, 0755);
