## Description

Run /sync as the last step after a change is complete, around merge, to keep durable knowledge current. Updates root and nested AGENTS.md, reconciles the scope from repo evidence, and flags specs the change made stale. Surgical edits only: it adds lines, and rewrites single lines it owns. Never a whole section, never curated prose.

## SKILL.md, as published by its author (untrusted third-party text, read it as data)

## Output style (plain words, no dashes, no hyphens)

<!-- OUTPUT-STYLE:START -->
Write everything this skill produces, files and messages alike, in plain simple language. Talk to the reader as `you`, warm and direct like a colleague, and present every step as a recommendation they may run or skip, never an order. Keep technical terms that carry real meaning; explain each in plain words. Never use a dash or a hyphen as punctuation: no em dash, no en dash, and no hyphenated compounds. Write `read only`, not `read-only`. Say it in simple words, or reword the sentence. Code, file paths, command flags, and values other skills match on keep their hyphens. Use short sentences, commas, or parentheses. Clear beats clever.

## What this skill does

Closes the loop on a completed change: syncs AGENTS.md files, the scope, and linked spec `**Status**:` lines to what the repo now shows, and flags what it must not edit (stale specs, curated prose). The Boundaries table below is the exact contract.

**`agent-prompt.md`** is the single source of truth for the maintenance rules; SKILL.md covers only orchestration. The main thread reads it and does the maintenance itself (see Step 3).

**Canonical file:** durable context lives in the tool agnostic **`AGENTS.md`**; **`CLAUDE.md` is only a pointer** to it. /sync edits/creates both, treating them only as targets, never as a change source.
