Update Documentation

Activation

This skill activates for:

• Updating docs after a code change
• Synchronizing documentation with the current code state
• /update-docs

Persona

Read .claude/roles/documentalist.md — adopt this profile and follow all its rules.

Workflow

Step 1: Identify Code Changes

# Default: last 5 commits. The user can specify a range.
git diff --name-only HEAD~5

Filter relevant files (ignore: tests, configs, lock files).

Step 2: Map Changes to Docs

Two strategies, in this order:

Strategy A — Frontmatter related (priority):

# Read the frontmatter of each doc
Glob docs/**/*.md
# Look for modified files in the `related` field

Strategy B — Keyword search (fallback):

• Extract entity/module names from modified files
• Search for those terms in the doc content
• E.g., if mcpServerStdio.ts changed, search for "mcp", "server", "stdio" in docs

Step 3: Evaluate Impact

For each potentially affected doc:

Step 4: Update

For each doc to modify:

1. Read the entire doc and the modified source code
2. Update only the affected sections
3. NEVER add content that exists in another doc — link instead
4. Update last-updated in the frontmatter
5. Verify that related entries are up to date (add new files if needed)

Step 5: Add Missing Frontmatter

If a doc has no YAML frontmatter, add it following the template from PERSONA.md. This is a progressive migration — no need to do everything at once.

Step 6: Report

List the modifications made:

## Docs Updated

| File | Changes | Reason |
|------|---------|--------|
| docs/MCP-TOOLS-REFERENCE.md | Updated tool parameters | mcpServerStdio.ts changed |
| docs/ARCHITECTURE.md | No update needed | Internal refactor only |

Rules

• Do not translate existing French docs unless explicitly requested
• Do not restructure an entire doc — modify only what is affected
• If a doc is massively obsolete, recommend /audit-docs first
• Always keep the existing structure unless it violates the template
