logic-lens

Run the Logic-Lens skill-improvement loop end to end — baseline → diagnose failures → edit → sync cache → re-eval → verify net gain → iterate until clean. Use whenever the goal is to RAISE a skill's eval score or fix a failing eval mode: "improve logic-review", "the format compliance is failing, fix it", "iterate on this skill until the evals pass", "raise the score", "re-run the loop on the latest failures", "run another iteration", "tune the skill description / disambiguation table against the evals". Also use to RESUME a prior loop ("continue improving from where we left off", "do another pass", "iterate further"). Do NOT use for: a one-off question about a skill, shipping a release (use bump-version), or scaffolding a brand-new skill (use new-skill).

Run the Logic-Lens content-eval pipeline for one iteration and produce a scored summary.json — use to measure a skill change. Wraps scripts/run-content-evals.sh (runner, costs tokens) and scripts/grade-iteration.py (grader, free, re-runnable). ALWAYS sync the plugin cache first. Use when the user wants to "run the evals", "score this iteration", "measure the skill change", "smoke-test before the full run", or "re-grade existing outputs".

Sync the Logic-Lens working-copy skills/ into the installed plugin cache so content-evals test the EDITED skill, not the last published one. ALWAYS run this after editing any skills/**/SKILL.md or guide/_shared file and BEFORE running content-evals — otherwise the eval silently grades stale content and every token is wasted. Also use to verify the cache is in sync ("is the cache fresh?", "did my edit take effect in evals?", "check skill cache drift").

Find logic bugs in a single file or function via semi-formal execution tracing (Premises → Trace → Divergence → Trigger → Remedy). Trigger when a user shares code and suspects something is wrong without naming a concrete failure — phrases like "review this", "does this look right", "check this function", "audit this code", "tests pass but prod fails". SCOPE HARD RULE: one file or one function only. For a directory or whole module use logic-health; for a confirmed failure (stack trace, failing test, specific wrong value) use logic-locate; for two versions use logic-diff; for repo-wide autonomous fixing use logic-fix-all. Do NOT trigger for: style/formatting, security scanning, performance, test generation, architecture or design questions.

Bump the Logic-Lens version across all six metadata locations at once (package.json, the four plugin manifests, and the README badge), then validate. Use when cutting a release or when `npm run validate` reports a version mismatch.

Scaffold a new logic-* skill in the Logic-Lens repo and wire it into every place a skill must be registered, so no step is missed. Use when adding a seventh (or later) skill to Logic-Lens.

Compare two code versions for semantic equivalence via semi-formal tracing of both versions side-by-side. Trigger when the user shares a refactor, rewrite, migration, or A/B implementation and wants to confirm behavior is unchanged — "did I break anything", "is this equivalent", "are these equivalent", "semantically equivalent", "are these two implementations semantically equivalent", "check my refactor", "same behavior after the change?", "does my rewrite produce the same output", "switched from X to Y — same results?". SCOPE HARD RULE: requires two code versions (A and B). A single version for bug-finding uses logic-review; one version + a failing test uses logic-locate; explaining what one piece of code does uses logic-explain; codebase audit uses logic-health. Do NOT trigger for: single-version review, performance comparison, design-quality comparison, or "which is better-written" questions.

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.

Locate the root cause of a CONFIRMED failure via backward-then-forward semi-formal tracing. Trigger when the user provides a stack trace, failing assertion, error message, or specific wrong-value observation — "find the bug", "this test is failing", "track down this crash", "why is this test failing", "KeyError at line 89", "expected 70, got 100", "NoneType has no attribute X", "cart empties when second tab opens". SCOPE HARD RULE: requires a concrete failure (exception, failing test, or specific wrong output). Vague suspicion without evidence uses logic-review; behavior explanation uses logic-explain; refactor comparison uses logic-diff; codebase audit uses logic-health. Do NOT trigger for: vague "what's wrong" without a concrete symptom, style questions, or performance issues.

Explain what a specific piece of code actually does for a given input by producing a step-by-step execution trace (interprocedural, with name resolution and type transitions). Trigger when the user is confused about behavior or asks why code produces X instead of Y — "walk me through this", "trace through X with input Y", "why does this return X", "what does yield-from do here", "explain the execution path". SCOPE HARD RULE: a specific function + a specific input scenario. If the user wants to find bugs without a scenario in mind, use logic-review; two-version comparison uses logic-diff; concrete failures use logic-locate; codebase-wide audit uses logic-health. Do NOT trigger for: finding bugs without a behavioral question, style or design discussion, or concept explanations not tied to specific code.

Autonomous repository-wide audit-and-fix pipeline: health → review → locate/explain → fix → diff-verify → iterate until clean. Starts with a mandatory consent prompt (token-intensive); after consent runs hands-free. Trigger when the user wants ALL logic issues found and fixed — "fix everything", "fix all logic issues", "fix all logic issues in this code", "clean up all logic issues", "audit and fix the whole repo", "fix all bugs automatically", or frustration with recurring bugs wanting a one-shot pass. SCOPE RULE: repo-wide by default; also trigger for a pasted code snippet when the user says "fix all" — produce the full Fix Report (Fix Log, before/after Logic Score). Analysis-only requests use logic-health or logic-review. Single failure uses logic-locate. Two versions uses logic-diff. One path explanation uses logic-explain. Do NOT trigger for: analysis-only ("show me the bugs"), style/lint/format concerns, or fixing a single named finding.
