## What it does

This skill establishes an editorial workflow based on Chris Banes's writing style. It keeps reasoning visible and requires every claim to rest on supplied evidence or verified public facts. The agent must never invent personal experiences, benchmark numbers, or subjective opinions. If a missing personal position would alter the argument, the model pauses and asks.

For public developer documentation, the skill strips internal mechanics and highlights observable differences and API contracts. Diagnostic details remain only in internal design documents and technical reports where they serve a direct purpose. Reviewing happens in two distinct passes: first for truth and material accuracy, then for tone and style.

Drafting prose in the chat output does not authorize file edits in the repository.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add chrisbanes/skills --skill grounded-writing -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add chrisbanes/skills --skill grounded-writing -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add chrisbanes/skills --skill grounded-writing -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install chrisbanes/skills grounded-writing
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add chrisbanes/skills --skill grounded-writing -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/chrisbanes/skills --path skills/grounded-writing
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add chrisbanes/skills --skill grounded-writing -a opencode
```

### Claude.ai

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

## When to use it
- Review public developer documentation without leaking implementation details
- Strip promotional framing and unsupported certainty from drafts
- Check internal technical reports for factual claims and material errors
- Draft concise replies to technical pull request reviews

## Example prompts
- Review this draft of our new API documentation and flag any unsupported claims.
- Edit this architecture decision record using grounded-writing principles.
- Draft a concise reply to this pull request review comment without promotional filler.

# Grounded Writing

## Core principle

Use Chris Banes's writing as the sole style model. Make the reasoning visible
at the scale the artifact supports. Preserve the user's meaning and evidence; remove anything invented, generic, or included
only to imitate a personality.

## Procedure

1. Establish scope and authority. Apply this skill to text the user will publish
   or send, at any length, or to an explicitly requested editorial review of
   their own draft. Identify whether the task permits drafting, editing, or
   recommendations only. Preserve the audience, purpose, and requested format.
   Exclude ordinary assistant replies, quoted source text, and prose attributed
   to someone else. For internal report reviews, apply truth and material-edit
   checks without imposing public-documentation style.
2. Establish the evidence and the user's actual position. Never invent personal
   opinions, experiences, results, preferences, memories, or certainty. Research
   discoverable public facts when research is in scope. If a missing personal
   position would materially change the text, ask and pause that part. Otherwise
   qualify uncertainty or mark a necessary gap conspicuously; do not add
   placeholders for details that do not affect the artifact's intended use.
3. Select detail for the reader. When public developer documentation compares
   options, check the observable difference, practical trade-off, and when to
   choose each separately. Preserve supported public contracts, shared guarantees (including
   compatibility), meaningful limitations, and context needed to interpret claims.
   Include implementation mechanics only when required for correct API use,
   necessary to distinguish a reader-facing choice, or explicitly requested.
   In reviews, explicitly recommend removing each irrelevant mechanic and name
   missing decision information rather than inventing it or asking for more
   internals. Distinguish behavior from implementation: preserve a supported
   return to another setting even if its timing is unverified; omit the internal
   timing term and delay unless their public or decision relevance is established.
   Verify uncertain contracts or relevance when research is in scope; otherwise
   flag material gaps rather than silently dropping or inventing behavior.
   Internal reports and design documents may need
   implementation and diagnostic detail; retain it for their intended use.
4. Read [the style profile](references/style-profile.md) and shape the argument
   before polishing. Use only the reasoning the artifact needs: a concrete
