Logic audit locates contradictions and reasoning gaps in specifications, plans, and prose. It verifies claims against sources and drafts minimal fixes.

## What it does

The skill audits claims, requirements, and proof across documents, policies, or research notes. It maps dependencies from premises to conclusions and flags missing links or unsupported statements. When validating external premises, it queries primary web sources. A search snippet is treated merely as a lead rather than proof.

Each issue enters a structured ledger with impact ratings and candidate counterexamples. Instead of rewriting whole documents, the skill applies the smallest coherent fix: scope adjustments, explicit premises, or reconciled constraints. When dealing with code errors, it outlines the logical contract and leaves root-cause execution to `systematic-debugging`.

The workflow requires three companion skills: `always-current-datetime`, `starting-point`, and `outcome-bounded-work`. Running `mise run validate` is mandatory before accessing packaged files.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add srinitude/skills --skill logic-audit -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/logic-audit/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/logic-audit/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add srinitude/skills --skill logic-audit -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/logic-audit/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add srinitude/skills --skill logic-audit -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/logic-audit/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install srinitude/skills logic-audit
```

2. **Manually: put the files in place**
- File: `.github/skills/logic-audit/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add srinitude/skills --skill logic-audit -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/srinitude/skills --path skills/logic-audit
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/logic-audit/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add srinitude/skills --skill logic-audit -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/srinitude/skills/tree/HEAD/skills/logic-audit/SKILL.md

## When to use it
- identify contradictory constraints in technical specifications
- spot unsupported inferential leaps between premises and conclusions
- verify externally checkable claims using primary web sources
- reconcile conflicting policy rules into a consistent contract

## Example prompts
- Audit `specs/requirements.md` for contradictions and unsupported claims.
- Find logical gaps between our architecture proposal and the security policy.
- Reconcile conflicting constraints in `docs/plan.md` without rewriting the whole document.

# Logic audit

## Outcome

Find and repair material contradictions and missing links across claims, requirements, evidence, actions, and proof. Preserve authority and intent. Don't invent premises, erase real uncertainty, or weaken an exact requirement.

## Trigger and boundary

Use when a user asks to find, explain, reconcile, or repair logical inconsistencies, omissions, unsupported claims, conflicting requirements, incomplete cases, or gaps between an objective and its proof.

Use it for prose, policies, plans, specifications, research, decisions, and mixed source sets. For code failures, hand root-cause execution to `systematic-debugging` after this skill identifies the logical contract. For a formal theorem, use a proof assistant or solver when available and limit claims to what it verifies. Routine fact lookup alone doesn't trigger this skill.

A full audit is bounded by the named source set and outcome. Never claim that an open world has no possible gap.

## Required composition

Before auditing:

1. Load `always-current-datetime` and acquire its clock anchor.
2. Load `starting-point` and build its private outcome map.
3. Load `outcome-bounded-work` and classify fixed requirements, proof duties, boundaries, forbidden outcomes, mandatory methods, candidate routes, and unknowns.
4. Keep the same `as_of` anchor throughout the audit. Reacquire only after a new direct user turn or local midnight.

These skills remain the owners of date handling, the outcome map, and invariant-versus-recipe classification. This skill owns consistency and gap analysis.

## Evidence setup

1. Name the exact source set, authority order, versions, dates, and excluded material.
2. Read each source in full when accessible. If truncation remains, mark the omitted range and don't pass the whole source.
3. Give every material statement a stable source ID in source order.
4. Classify each statement as definition, fact, assumption, requirement, boundary, exception, evidence, inference, action, conclusion, or unknown.
5. Normalize terms, entities, references, quantifiers, modal verbs, units, time windows, versions, and scope before calling two statements inconsistent.

## Web evidence contract

Use every available source-relevant web capability with a clear purpose. Do not fire low-level actions that cannot change the finding.

1. Inventory current search, source extraction, rendered browser, social-source, academic, and domain-source capabilities. Inspect an unfamiliar capability's contract before use.
2. Keep a capability ledger with one row per distinct source-relevant capability. Mark each `USED`, `NOT_APPLICABLE` with a reason, or `UNAVAILABLE` with the observed failure. Every available relevant capability must be used.
