Skill: docs-sync

When to Use

Run this skill after any change that:

• Adds or removes a FastAPI endpoint
• Adds or removes an environment variable
• Changes agent capabilities or planner/executor/verifier behaviour
• Changes model routing logic or adds a new model
• Adds a new dependency to requirements.txt
• Modifies the admin dashboard or Telegram bot

Docs to Check After Each Change Type

Change	Docs to update
New endpoint	README.md, docs/configuration-reference.md
New env var	README.md, docs/configuration-reference.md, .env.example
New model or routing change	docs/model-routing.md, router/CLAUDE.md
New agent capability	docs/features.md, agent/CLAUDE.md
Admin dashboard change	docs/admin-dashboard.md
Telegram bot change	docs/telegram-bot.md
Architecture change	docs/architecture/overview.md, relevant ADR
New ADR decision	docs/adrs/ — write a new ADR
New dependency	docs/configuration-reference.md if setup-relevant
Breaking change	docs/changelog.md ### Changed or ### Removed

Instructions

1. Identify which doc files need updating (use the table above).
2. Read the current doc file content.
3. Make the minimal accurate update.
4. Use clear present-tense language ("The proxy exposes..." not "The proxy will expose...").
5. Verify all code snippets and example commands still work after your changes.
6. Update CLAUDE.md (root or module-level) if the operating instructions changed.

CLAUDE.md Update Rules

Root CLAUDE.md changes when:

• Key commands change
• New risky modules are introduced
• Skill-to-situation mapping changes
• Codebase structure changes significantly

Module CLAUDE.md changes when:

• Module invariants change
• New env vars are introduced
• Security surface changes

ADR Guidelines

Write a new ADR in docs/adrs/ when:

• A significant architecture decision is made
• A new technology or pattern is adopted
• An existing approach is replaced with something different

ADR filename: NNN-short-title.md where NNN is the next sequential number.

ADR template:

# ADR NNN: <title>

**Status:** Accepted | Superseded by ADR NNN
**Date:** YYYY-MM-DD

## Context
Why is this decision needed?

## Decision
What was decided?

## Consequences
### Positive
### Negative / Trade-offs
### Neutral

Acceptance Checks

• All relevant doc files updated
• No code examples in docs are stale
• CLAUDE.md updated if operating instructions changed
• ADR written if architecture decision was made
• Changelog updated
