project-notes-context

project-notes-context is a skill for Claude Code, Codex from mitszo/agent-notes-mcp. It costs 66 tokens per session (1,584 once invoked), scanned A, original, MIT.

A skill for keeping project-specific work context in private local notes separate from the code repository. It defines how to read and update rules, project overviews, handoffs, inbox items, and decisions.

In plain words
What is it for?
Loading repository-specific guidance, reading project overviews and handoffs, reviewing relevant inbox notes or past decisions, and updating approved persistent project information.
Why use it?
It preserves important project context between tasks without adding those notes to the repository, while allowing work to continue if the notes system is unavailable.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

project-notes-context scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 46 lines — stays where its author put it; the contents beside it link to each section on GitHub.

プロジェクトノートのコンテキスト

プロジェクト固有の作業コンテキストを、リポジトリとは分離した private なローカルノートに保つ。この例では root ID を notes-work、ノートの配置を rules/ と projects/ とする。別の root ID や配置を使う場合は、スキル全体を自分の環境へ合わせて変更する。

コンテキストの読込み

  1. Git ルートから現在のリポジトリ名を取得する。Git リポジトリでなければ処理を止める。
  2. agent_notes MCP ツールと notes-work root が利用できる場合、まず rules/ を列挙する。プロジェクトノートを扱う作業では、project-notes- で始まる現在の共通規約を読む。
  3. 既知の正本である projects/<repository-name>/overview.md と projects/<repository-name>/handoff.md は、列挙せず read_note で直接読む。どちらかが存在しない場合は、そのノートなしで続ける。
  4. inbox は root_id: notes-work、path_prefix: projects/<repository-name>/inbox/、status: ["new", "triage"] を指定して list_notes で列挙し、現在の作業に関係するノートだけを read_note する。
  5. 過去の判断理由が現在の作業に関係する場合だけ decisions.md を読む。
  6. ノート、root、MCP サーバーが存在しない・利用できない場合はブロッカーにしない。リポジトリのコンテキストだけで作業を続け、ノートがないことだけを理由に新規作成しない。

コンテキストの更新

  • ユーザーが依頼した場合、またはユーザーが保存に合意した永続的な判断が生まれた場合だけ、プロジェクトノートを作成・更新する。
  • overview.md はプロジェクトの恒久的な概要、構成、技術選定、設計原則を扱う。handoff.md は現在のブランチ、未コミット変更、検証結果、現行の重要事項、次の行動を扱う。どちらも古い内容を追記で打ち消さず、現行の正を直接更新する。
  • handoff.md に有効な管理ブロック(<!-- agent-notes:managed <id> --> と対応する終端)がある場合は、read_note で取得した SHA-256 を指定して update_managed_blocks を使う。現在地として整合させる複数のブロックは、一回の呼出しでまとめて更新する。
  • 管理ブロックがない既存 handoff は、全文を読んだうえで SHA-256 付きの置換を使う。管理ブロックの導入はノート構造を変えるため、ユーザーが明示的に依頼または合意した場合だけ行う。管理ブロックが壊れている場合は推測して更新せず、書込みを行わずに原因を報告する。
  • 複数の既存ノートを整合させるときは、対象すべてを先に読み、それぞれの SHA-256 を指定して batch_update_notes を使う。作成と移動は一括更新に混ぜない。
  • 日付・判断・理由を簡潔にした記録を decisions.md に追記する。ブランチ固有の実装詳細・調査・検証・PR は branches/ に残す。
  • activity_log が有効な場合、永続的な判断・成果・次の行動を残す更新には、ユーザーの依頼または判断を主語にした簡潔な activity_summary を添える。機械的な更新や一時的な試行には付けない。
  • ノートを置換・移動する前には必ず読込みを行い、更新時に得た SHA-256 を指定する。

branch ノートの再照合

  • Git リポジトリで実質的な作業を再開する時だけ、branches/ を対象に lifecycle: active のノートを列挙し、候補を読んでローカル Git の現在ブランチ、HEAD、ローカルブランチ一覧、作業ツリーと照合する。
  • 全ローカルブランチを個別に評価しない。ノートの HEAD と実際の HEAD が異なるもの、ノート記載のブランチがローカルにないもの、非 base branch なのに対応する active ノートがない現在ブランチだけを、まとめて更新候補として報告する。
  • 再照合そのものは読取り専用である。ユーザーが反映を依頼した場合だけ、対象ノートを再読込みして SHA-256 を指定し、安全な更新操作を行う。

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
