CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

What this is

A single-file writing skill (SKILL.md) that audits and rewrites content to remove AI writing patterns. No build system, no dependencies, no tests — the skill is a markdown file consumed by AI coding assistants.

Repository structure

• SKILL.md — the skill itself (v3.7.2). This is the product. All rules, tiers, profiles, and output format live here.
• README.md — public-facing docs, installation instructions, pattern reference table, full before/after example.
• CHANGELOG.md — version history with what changed and why.

How to make changes

Edit SKILL.md directly. There's nothing to build or test. When making changes:

• Bump the version in the SKILL.md frontmatter (version: X.Y.Z)
• Add a dated entry to CHANGELOG.md
• Update README.md if the change affects installation, usage, feature list, or pattern count
• The pattern count lives in one place — the README "46 pattern categories" bullet — and is derived from SKILL.md's detection ### entries. Don't restate it elsewhere; CI (scripts/check-pattern-count.sh) fails the build if the README number drifts from SKILL.md, so just add the new ### entry and bump the README bullet.

Architecture of the skill

The skill has three modes (rewrite default, detect flag-only, edit in-place) and processes text through this pipeline:

1. Context profile detection — auto-detects or accepts a profile hint (linkedin, blog, technical-blog, investor-email, docs, casual) that adjusts rule strictness via the tolerance matrix
2. Pattern matching — detection categories across content, language, structure, communication, and meta patterns (see SKILL.md for the catalog; the count is in the README bullet)
3. Vocabulary flagging — 3-tier system: Tier 1 (always flag), Tier 2 (flag in clusters), Tier 3 (flag at high density)
4. Severity classification — P0 (credibility killers), P1 (obvious AI smell), P2 (stylistic polish)
5. Output — rewrite mode: 4 sections including a second-pass audit; detect mode: 2 sections with problem vs. judgment-call assessment

Key constraints

• The skill must remain a single SKILL.md file with agentskills.io-compatible frontmatter
• Word replacement table entries need specific alternatives, not just "rephrase"
• The self-reference escape hatch (quoted examples exempt from flagging) must be preserved — without it the skill flags its own documentation
• Technical-blog profile has explicit word table exceptions (e.g., "robust" and "ecosystem" are legitimate in technical contexts)
• "Extra strict" and "skip" in the tolerance matrix have specific meanings defined in the file

Compatibility

The skill works with Claude Code, OpenClaw/ClawHub, and any agentskills.io-compatible agent. The frontmatter includes both agentskills_spec and openclaw fields. Changes must not break either format.
