Summary

First step of the repository cleanup the owner approved after the repository audit. The root rules become a short map that agents can load on every task.

• AGENTS.md
  • Rewritten from 124 to 76 lines: a table of where things live, the four workflow skills, which checks to run, and the research, security and working rules in short form.
  • Removes pointers to dated records (the C1→C3 upgrade record, migration history).
  • Removes the stale "the active control plane is Python" statement; it now says the control plane is moving to TS by route group under ADR-0050.
  • The Chinese translation is rewritten to match.
• CLAUDE.md (new) imports AGENTS.md, so Claude Code loads the same map as Codex.
• .agents/README (en and zh) shrinks to a pointer; the skill table now lives only in the map.
• docs/REPOSITORY_MAP (en and zh): the header drops history pointers and the stale control-plane statement.
• Translations. The owner decided to keep Chinese translations only for user-facing docs, so the rule now names that set. README.ja.md and README.pt-BR.md are deleted (both described an older release).
• Check. check-developer-entrypoints now fails when the root map exceeds 90 lines, or when CLAUDE.md is missing or does not import @AGENTS.md.

No product code changes. Files that open PRs touch are left alone: OPEN_SOURCE_REUSE, the TS migration records and ci-selection.ts (#212), and docs/PLUGINS (#211). Research records and old plans go in a follow-up PR after #212 merges.

Open-source research

• Research artifact: Claude UI migration: sidebar lifecycle, unread, audit, settings and notifications #108 and docs/decisions/0020-open-source-first-feature-gate.md
• Selected upstream/standard: The AGENTS.md convention read by Codex, with a CLAUDE.md that imports it for Claude Code; no library involved
• Version or commit: Node.js 22 built-ins only; no dependency added or changed
• License: Not applicable; no third-party source added
• Decision: keep one short root map shared by every agent, with nested rules and CONTRIBUTING for detail, and enforce its size and the CLAUDE.md import in the existing entry check
• OpenBot-specific gap: the line budget and the import requirement are OpenBot conventions; research, security and product boundaries keep their meaning
• Source copied or substantially adapted: no

Checks

• node --test scripts/check-developer-entrypoints.test.ts: 5 pass. The new test covers the over-budget map, a CLAUDE.md without the import, and a missing CLAUDE.md.
• npm run docs:check: passed for 600 Markdown files.
• npm run check (lint on tracked paths): passed.
