wiki-harvest

wiki-harvest is a skill for Claude Code from shimo4228/claude-harness. It costs 177 tokens per session (5,531 once invoked), scanned A, original, MIT.

A read-only tool that scans an Obsidian vault, a folder of linked Markdown notes, and finds research ideas that could change the next steps in a code repository. It saves a ranked, source-linked list in the repository’s .notes folder.

In plain words
What is it for?
Use it to review research notes for actionable ideas, rank them, attach original sources, and record where they may affect a repository.
Why use it?
It turns broad wiki knowledge into a short list of repo-specific candidates without changing the original notes. Each candidate is tied to a source and a place where it could be used.

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

wiki-harvest 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 7d 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.

wiki-harvest — LLM wiki から研究 repo への還元

研究 repo セッションで実行し、LLM wiki(Obsidian Vault)の合成知識から その repo の次アクションを変えうる候補だけを抽出して、一次出典付きのランク付き候補台帳(ledger)を repo 内に生成する。

各研究 repo の CLAUDE.md「Research Wiki Consultation」節に passive prose で書かれている還元マップ(4カテゴリ)を、再現可能な能動手続きに形式化したもの。wiki の合成知識を diff → ランク付き候補 → repo 内 ledger に落とす。daily-research → wiki(合成層)→ repo(昇格)という一方向ループの最終辺を1コマンドで回す。

兄弟スキル: wiki-query = chat 上の自由 Q&A(良回答は wiki/concept/ へ書き戻す read-write)。wiki-harvest = repo 向け定型抽出 → 台帳で、wiki には書き込まない。置き換えではない。

Vault パス(固定)

VAULT="$HOME/Library/Mobile Documents/iCloud~md~obsidian/Documents/Obsidian Vault"
  • 概念ページ: $VAULT/wiki/concept/<概念名>.md
  • インデックス: $VAULT/wiki/index.md
  • 構造グラフ: $VAULT/wiki/graph.jsonld(symlink → ~/MyAI_Lab/daily-research/graph.jsonld
  • 原資料: $VAULT/daily-research/

この skill は shimo4228 の個人運用(固定 vault + 自分の研究 repo 群)に紐づく。repo→concept マッピングは skill にハードコードせず、各 repo の CLAUDE.md から読む(下記 Step 1)。

制約

  • wiki は read-only。この skill から vault 内のいかなるファイルにも書き込まない。wiki の更新(ingest / index / log)は vault セッションの /ingest の領域。一方向ループ(source → wiki → repo)を保全する。
  • 書き込みは repo 内の ledger のみ.notes/wiki-harvest/ledger.md(working/non-citable・gitignore 対象)だけを生成・更新する。
  • durable/citable な成果物(docs/adr/ / graph.jsonld / glossary.md / manifesto.md)には書かない。それらへの昇格は人間承認の別ステップ(reversibility gate + 既存ルール「promotion は repo author が判断」)。
  • prototype 系候補(response-type: prototype)のコード・計器も自動で実装しない。この skill は候補の抽出と triage までで、計器/spike の実行は人間承認の別ステップ。harvest がやるのは「何を測るべきか」を ledger に書くところまで。
  • iCloud dataless プレースホルダに注意: 読んだ concept ページ本文が空なら未ダウンロードの可能性。その旨を報告する。

手順

Step 1 — repo と対象 concept の特定

  1. cwd / git remote から現在の研究 repo を判定(agent-knowledge-cycle / agent-attribution-practice / contemplative-agent / authorship-strategy 等)。
  2. その repo の CLAUDE.md 内「Research Wiki Consultation」節を Read し、主担当ページ + 隣接 に挙がっている concept 名を取得する。マッピングはここ(repo 側)が正本。skill にハードコードしない。
  3. 節が無い repo は fallback(節を持つ repo のほうが少ない — 実測 2026-08-23 では agent-attribution-practice と authorship-strategy のみ。repo 名の列挙はすぐ腐るので grep 'Research Wiki Consultation' <repo>/CLAUDE.md で毎回確かめる): $VAULT/wiki/graph.jsonldtrack 値(akc / aap / contemplative / authorship)と repo 名から対象 concept を推定し、「consultation 節が欠落している」ことを報告する(後で節を backfill すべき signal)。

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.
