deep-review

name	deep-review
description	Run a deep multi-agent code review on a PR or git diff. Dispatches 5 specialist subagents (risk, security, pattern, tests, convention) in parallel and synthesizes a Markdown matrix report. Honors project CLAUDE.md as the highest source of truth.

Deep Review Orchestrator

Run a four-phase deep code review and emit a Markdown report.

Inputs

The user invokes via /morkit:deep-review <target> where <target> is one of:

• #<number> or <number> → GitHub PR number (uses gh pr diff <n>)
• --diff → uses git diff (working tree vs HEAD)
• --diff <ref> → uses git diff <ref>...HEAD
• (empty) → defaults to --diff
• --json (flag) → emit JSON instead of Markdown (Phase 3 mode)

Phase 1 — Ingest

1. Resolve target → produce a unified diff string.
   • PR: gh pr diff <n> (fail with clear message if gh missing or unauthenticated).
   • Diff: git diff or git diff <ref>...HEAD.
2. Parse diff to derive:
   • Changed file list.
   • Languages present (by extension): .ts/.tsx, .py, .go, .java, .rs, .cs, .php, .rb, .js/.jsx, etc.
3. Load convention sources in priority order:
   • Tier 1: project CLAUDE.md (read full content; if absent, mark "no CLAUDE.md").
   • Tier 2: matching profiles/<lang>.md files for each detected language (read from ${MORKIT_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}/profiles/).
   • Tier 3: universal rules (SOLID/DRY/KISS/YAGNI) — embedded below.
4. Graph pre-flight (CRITICAL UX step). Before dispatching specialists:

   1. Run bash ${MORKIT_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}/scripts/graph-status.sh and parse the key=value output.

   2. Cross-check with mcp__code-review-graph__list_graph_stats_tool if the helper indicates graph_present=true.

   3. Decide based on recommendation:

      recommendation	Behavior
      skip (graph already built)	Proceed to Phase 2 silently.
      auto-build (small repo, < 1500 files)	Print: "📊 Repo chưa có graph — đang build (~Ns cho N files)..." then call mcp__code-review-graph__build_or_update_graph_tool. Stream progress to chat.
      prompt-user (medium, 1500–8000 files)	Ask the user: "Repo này chưa có code graph (N files, ước tính ~Ns build). Build ngay để có review chất lượng đầy đủ? (y/N/skip)". On y → build with progress. On N or skip → continue in degraded mode.
      prompt-user-large (> 8000 files)	Strong warning: "⚠️ Repo lớn (N files, ước tính ~M phút build). Chỉ cần build 1 lần — sau đó mỗi diff < 2s. Build now (y) / Skip & degraded (N)?".
      not-applicable (not a git repo)	Fail fast: "❌ /morkit:deep-review requires a git repo."

   4. If user declines build OR build fails → continue in degraded mode (Phase 2 subagents fall back to grep/Read; report header notes the mode).

Phase 2 — Dispatch Specialists (PARALLEL)

Dispatch all 5 subagents in a single message with multiple Agent tool calls (parallel). Each subagent receives:

• The diff string
• The list of changed files
• The detected languages
• The Tier-1/Tier-2/Tier-3 convention bundle
• Instruction to cite CLAUDE.md line numbers when CLAUDE.md is the basis for a finding

Subagent	Agent definition	Primary tools
Risk & Impact Analyst	agents/risk-impact-analyst.md	code-review-graph: detect_changes_tool, get_impact_radius_tool, get_affected_flows_tool, get_bridge_nodes_tool, query_graph_tool
Security Auditor	agents/security-auditor.md	code-review-graph: semantic_search_nodes_tool, query_graph_tool, get_minimal_context_tool + Read/Grep
Pattern & Architecture Critic	agents/pattern-architecture-critic.md	code-review-graph: get_architecture_overview_tool, list_communities_tool, get_hub_nodes_tool, find_large_functions_tool, get_surprising_connections_tool
Test Coverage Auditor	agents/test-coverage-auditor.md	code-review-graph: query_graph_tool (tests_for), get_knowledge_gaps_tool
Convention Checker	agents/convention-checker.md	Read (CLAUDE.md + profile), Grep
Performance Auditor (Phase 2)	agents/performance-auditor.md	code-review-graph: get_hub_nodes_tool + Grep
Documentation Auditor (Phase 2)	agents/documentation-auditor.md	Read, Grep

Each subagent returns a YAML-Markdown findings block:

findings:
  - id: <S1|R1|P1|T1|C1|Pf1|D1>-<n>
    category: Security|Risk|Pattern|Tests|Convention
    severity: Critical|High|Medium|Low|Info
    file: path/to/file.ts
    line: 42
    title: short description
    detail: longer explanation
    source: "CLAUDE.md:L<line>" | "profile:typescript" | "universal:SOLID-S" | "graph:impact_radius" | "OWASP:A03"
    suggested_fix: code or text
    confidence: 0-100

Phase 3 — Synthesize

1. Merge findings from all 5 subagents.
2. Deduplicate (same file:line + same title).
3. Apply severity calibration matrix in ${MORKIT_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}/lib/severity-calibration.md (multiply weights by modifiers).
4. Rank: Critical first, then High, Medium, Low, Info.
5. Build executive summary:
   • Overall Risk: highest individual severity (capped at HIGH unless ≥2 Critical → CRITICAL).
   • Decision: BLOCK if any Critical; APPROVE WITH CHANGES if any High; APPROVE otherwise.
   • Confidence: weighted average.

Phase 4 — Output

1. Render ${MORKIT_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}/templates/report-template.md with computed values.
2. Print full report directly to chat.
3. Save to morkit/output/reviews/deep-review-<timestamp>-<target>.md if writable; otherwise skip silently.
4. If --json flag passed, emit JSON instead (see "JSON output mode" below).
5. Suggest next step at the end of the report based on Decision:
   • BLOCK → "Fix Critical findings, push fix commit, then re-run /morkit:deep-review <target>."
   • APPROVE WITH CHANGES → "Address High findings (or defer with justification), push, then merge."
   • APPROVE → "Ready to merge. After merge, close out the change with /morkit:archive <name> if this PR was linked to a morkit change."

Universal Rules (Tier 3, embedded)

• SOLID: Single-responsibility, Open/closed, Liskov, Interface-segregation, Dependency-inversion violations are findings.
• DRY: Three or more near-identical blocks → finding.
• KISS / YAGNI: Speculative abstraction, dead branches, unused parameters → finding.
• Cyclomatic complexity > 10 in changed functions → finding.
• Magic numbers (non-0/1/-1) without named constant → finding.
• Long methods > 60 lines (changed) → finding.
• Error swallowing (empty catch / pass on except / _ = err) → finding.
• Resource leaks (no defer/finally/with) → finding.

Tier-1 Override Rule (CRITICAL)

If CLAUDE.md states a convention that conflicts with the language profile, CLAUDE.md wins. Cite the CLAUDE.md line in source. Findings derived from a profile rule that is contradicted by CLAUDE.md MUST be suppressed and instead recorded as Info-level note "profile rule overridden by CLAUDE.md:L".

Failure Modes

Condition	Behavior
gh missing for PR target	Fail with: "Install GitHub CLI: brew install gh && gh auth login"
Graph build fails	Continue in degraded mode; subagents fall back to Read/Grep; report header notes "⚠️ Degraded mode (no graph)"
Empty diff	Print "No changes to review." and exit
Subagent timeout	Skip that subagent; report header notes which categories were skipped

Severity calibration

Apply the matrix in ${MORKIT_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}/lib/severity-calibration.md during Phase 3 (Synthesize). Multiply base weight by modifiers; recompute overall risk and decision per the matrix.

JSON output mode

When the invocation includes the --json flag, Phase 4 emits a JSON object instead of Markdown:

{
  "schema_version": 1,
  "target": "<PR# or diff ref>",
  "timestamp": "<ISO 8601>",
  "mode": "full | degraded-no-graph | degraded-no-gh",
  "overall": {
    "risk": "CRITICAL|HIGH|MEDIUM|LOW|INFO",
    "decision": "BLOCK|APPROVE_WITH_CHANGES|APPROVE",
    "confidence": 0
  },
  "convention_sources": {
    "claude_md_present": true,
    "language_profiles": ["typescript", "python"]
  },
  "findings": [
    {
      "id": "S1",
      "category": "Security",
      "severity": "Critical",
      "file": "src/auth.ts",
      "line": 42,
      "title": "...",
      "detail": "...",
      "source": "OWASP:A03",
      "suggested_fix": "...",
      "confidence": 95,
      "score": 110
    }
  ],
  "positives": ["..."],
  "actions": ["..."]
}

JSON mode is intended for CI/CD pipelines. Save to deep-review.json instead of morkit/output/reviews/*.md when --json is set.
