warning

warning is a skill for Claude Code, Codex from ncaq/konoka. It costs 49 tokens per session (657 once invoked), scanned A, original, Apache-2.0.

A Haskell code-review rule for keeping GHC and hlint warnings enabled, with narrow, documented exceptions inside individual modules.

In plain words
What is it for?
Use it when writing or reviewing Haskell code, Cabal files, or hlint settings, especially for orphan instances and unavoidable Template Haskell warnings.
Why use it?
It prevents project-wide warning suppression from hiding possible code problems and keeps exceptions visible near the code they affect.

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

warning 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 5d 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.

What it actually says

警告を無効にしない

GHCの警告は無効にしない

GHCの警告を無効にすることは原則禁止します。

例外

正当な理由がある場合は、 特定の警告を無効にすることを許可します。

cabalなどのプロジェクトファイルを編集するのではなく、 モジュール単位でアノテーションコメントを書いて無効化してください。

そのモジュールのコードが多い場合は、 警告と干渉するコードを別モジュールに切り出すことも検討してください。

孤立インスタンス

孤立インスタンスを定義する場合は許可します。

以下のように無効化してください。

{-# OPTIONS_GHC -Wno-orphans #-}

ただし孤立インスタンスの定義自体をなるべく避けるべきなので、 設計上どうしても仕方がないときだけにしてください。

Template Haskellで避けられない警告

Template Haskellを利用したコード生成で、 こちらから制御できない変数名のshadowingや、 未使用の束縛が発生する場合も、 無効にすることを許可します。

以下のように無効化してください。

{-# OPTIONS_GHC -Wno-shadowed-variables #-}
{-# OPTIONS_GHC -Wno-unused-binds #-}

hlintの警告は無効にしない

hlintの警告を無効にすることは原則禁止します。

例外

正当な理由がある場合は、 特定の警告を無効にすることを許可します。

hlintのルールファイルを編集するのではなく、 モジュール単位でアノテーションコメントを書いて無効化してください。

そのモジュールのコードが多い場合は、 警告と干渉するコードを別モジュールに切り出すことも検討してください。

その方法でしか書けない場合

ライブラリのAPIがhlintの警告とどうしても干渉してしまう場合などは、 無効にすることを許可します。

hlintのバグ

hlintのissueやPRを確認して、 バグであると判断した場合は無効にしても構いません。

まだ報告されていない場合も、 最小限の再現コードで確認して、 明らかに挙動がおかしいと判断した場合は無効にしても構いません。

Changes

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.

warning is a skill published in the GitHub repository ncaq/konoka (3 stars, last pushed yesterday), licensed Apache-2.0. It adds 49 tokens to every session and 657 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
