Skill0 starsChanged 6 days agoMITView on GitHub
不具合を調べて直すとき、審査やレビューの指摘を直すときに適用する。症状が出た場所でなく、系が最初に誤った場所まで遡って直す。防御の追加が修正になるのは、扱う状態が正当なときだけ。

ianclearySkillprinciple-explain-the-number
Apply before you trust, report, or act on a number you measured: a speedup, a regression, a throughput, a latency, or an eval result. Find what limits it, and rule out that it measured something other than the work you think.

How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

根本原因を直す
不具合は、症状が出た場所でなく、原因の場所で直す。症状は誤った状態が見えた場所で、根本原因は系が最初にしてはいけないことをした場所、または扱うべき状態を扱えなかった場所。
なぜ: 症状の手当ては証拠を隠し、欠陥を別の場所に出させる。名前の無い不具合への回避策がコードに残り、系を追いにくくする。
適用する場面:
- 試験や CI が落ち、落ちた行の近くで直そうとしたとき。
Noneの確認・再試行・例外の握りつぶし・値の切り詰めを足して通そうとしたとき。- 再起動の後にだけ起きる失敗を見たとき。
- 審査やレビューの指摘を直すとき(指摘の文は、見つけた 1 か所の形で書かれる)。
やること:
- まず再現する。各段で「なぜ」を問い、答えが前の段の結果でなく、コードの誤った判断になるまで遡る。推測せず、実際のエラーと実際の状態を出して読む。
- 症状を起こした状態が正当かを問う。正当なら、それで壊れたコードが原因で、そこで扱うのが修正。ありえない状態なら、壊れた場所の確認は不具合を隠すだけなので、状態を作った場所を探す。再起動の後だけ落ちるなら、残った状態(設定・キャッシュ・ロック・保存した状態)を先に疑う。
- 1 件でなく型を探し、同じ欠陥を持つ場所をすべて直す。指摘を直すときは、直す前に根の性質を 1 文で書き(例: 「fixture を準備した結果が、意図した状態になったかを確かめない」)、道具や書き方が違っても同じ性質の箇所を grep などで探す。回避策に段落ほどの注釈が要るなら、直すべきはコード。決め手の事実を深く掘って見つけたなら、最初に見れば分かる安い手がかり(ログの 1 行、状態の表示)を常に出す案を出す。
使わないとき: 原因がこちらで直せない外部(他社の API、ホストの不具合)にある場合。回避策を置き、原因と外す条件を同じ場所に書く。
確かめる例: 修正の説明に、症状・根本原因・その状態が正当かの判断がある。同じ欠陥のほかの箇所も、同じ差分で直っている。
Does it work?

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
