logic-health

name

logic-health

description

Sweep a directory, module, or full codebase for logic correctness and produce a scored health dashboard with systemic patterns. Trigger when the user requests a health view — "audit the whole codebase", "health check", "health overview", "logic health overview", "audit src/", "audit auth and payments modules", "where should I focus testing", "onboarding review", "logic overview before we ship", "give me a health overview of this module". SCOPE RULE: prefer multi-file; also trigger for a single module when the user explicitly uses "health check", "health overview", or "logic health" — a concrete failure uses logic-locate; two versions uses logic-diff; explaining a path uses logic-explain; "fix everything" uses logic-fix-all. Do NOT trigger for: style/architecture-only audits, security-only scans, performance-only audits.

Logic-Lens — Logic Health

Setup

Use lazy loading per ../_shared/common.md §13:

1. Read ../_shared/common.md only for language, Iron Law, Logic Score, scope routing, Remedy discipline, config fields, and loading budget.
2. Read only the relevant step in logic-health-guide.md as you reach it.
3. Load ../_shared/logic-risks.md, ../_shared/semiformal-guide.md, ../_shared/semiformal-checklist.md, ../_shared/report-template.md, and ../logic-review/logic-review-guide.md on demand when the current module trace needs them.

Process

Step 0. Language + scope routing. Detect language per common.md §1. Proceed for multi-file scopes and for single-module scopes when the user explicitly uses "health check", "health overview", or "logic health". If scope is one file and none of those health phrases appear, switch to logic-review.

Step 1. Enumerate modules and plan the sweep (guide Step 1) — prioritize public API surfaces, recently changed files, and user-flagged modules. Read .logic-lens.yaml only for ignore:, focus:, disable:, severity:, custom_risks, and trace.* fields. For broad scopes, build a ranked worklist before opening files.

Step 2. Run focused logic-review per module (guide Step 2) — apply Premises → Trace → Divergence on public-facing functions; skip internal helpers unless a trace leads into them. Apply the per-module function budget from guide Step 2 (small/medium/large line-count tiers) — do not trace all functions in large modules.

Step 3. Record findings per module (guide Step 3) — tag module, L-code, severity.

Step 4. Aggregate findings (guide Step 4) — counts by severity and by L-code; cross-reference modules.

Step 5. Compute scores (guide Step 5) — per-module Logic Score via the standard formula; overall score is the line-weighted average (per common.md §6).

Step 6. Identify systemic patterns (guide Step 6) — L-codes appearing in ≥ 3 modules or ≥ 30% of scanned modules (whichever threshold is lower) indicate codebase-wide habits; architectural enablers (heavy global state → L7; deep callee chains → L6) get explicit mention.

Step 7. Output the Health Report (guide Step 7) — standard header; Findings; Summary; then Module Breakdown, Systemic Patterns, and Recommended Priority Order (top 3–5) appended after Summary. Localize all headers if the user wrote in Chinese.

Mode line in report: Logic Health (Chinese: 逻辑体检).

Health-specific additions (append after the standard Summary):

## Module Breakdown

| Module | Score | Critical | Warning | Suggestion | Top Risk |
|--------|-------|----------|---------|------------|----------|

## Systemic Patterns
[Risk codes appearing in ≥ 3 modules or ≥ 30% of scanned modules — codebase-wide habit rather than isolated bugs]

## Recommended Priority Order
1. [Most critical single finding]
2. [Systemic pattern with widest impact]
3. [Quick wins: suggestions that prevent future Criticals]

Localize column and section headers when the user wrote in Chinese (e.g., 模块分布, 系统性模式, 优先级建议).
