fix

fix is a skill for Claude Code from MichiBl/Claude-Code-Default-Repo. It costs 98 tokens per session (636 once invoked), scanned A, original, MIT.

A fast workflow for clearly defined bug fixes, small refactorings, and documentation or configuration updates.

In plain words
What is it for?
Use it when you type /fix or ask for a specific correction that does not need requirements or architecture planning.
Why use it?
It helps find the underlying cause, add a regression test for bugs, and keep the change small. It is not intended for new features or broad architectural work.

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

fix 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

/fix — Fast Lane für kleine Änderungen

Du behebst eine klar umrissene Änderung direkt — ohne Requirements-Gate, ohne Architektur-Gate, ohne Subagenten. Die Qualitätssicherung übernimmt der Stop-Hook (.claude/hooks/verify.sh): Er lintet und testet automatisch am Ende jeder Antwort. Baue keine eigenen Gates nach.

Wann nutzen / wann nicht

Nutzen: Bugfix mit klarer Symptombeschreibung, kleines Refactoring (1–3 Dateien), Doku-Update, Konfigurations-Korrektur.

Nicht nutzen: neues Feature, Refactor über viele Dateien, alles was Schema + Backend + UI zugleich berührt (-> /feature), reine Fragen (direkt beantworten). Reiner Typo/Einzeiler: einfach fixen, dieser Workflow wäre schon Overhead.

Workflow

  1. Ursache statt Symptom. Lokalisiere die tatsächliche Ursache (Lesen/Grep, ggf. Reproduktion). Fixe nie nur die Stelle, an der der Fehler sichtbar wird, wenn die Ursache woanders liegt.
  2. Regressionstest zuerst (bei Bugs). Schreibe einen Test, der den Bug reproduziert und rot ist. Ausnahmen: keine Test-Infrastruktur vorhanden oder nicht sinnvoll testbar (z. B. Doku, Kommentar, Config) — dann in einem Satz begründen, warum kein Test.
  3. Minimale Änderung. Setze den kleinsten Fix um, der die Ursache behebt und den Test grün macht. Respektiere Konventionen und harte Grenzen aus CLAUDE.md. Keine Gelegenheits-Refactorings im selben Fix.
  4. Verifikation läuft automatisch. verify.sh (Stop-Hook) führt Lint/Typecheck/Tests aus und blockt, bis alles grün ist — nicht manuell duplizieren.
  5. Commit. Conventional Commit (fix: / docs: / chore: / refactor:). Kein Artefakt unter docs/features/ — das ist der Pipeline vorbehalten.

Eskalation

Stellt sich mittendrin heraus, dass die Änderung größer ist als gedacht (neue Dependencies, Schema-Änderung, > ~3 Dateien Produktivcode, unklare Anforderungen): stoppe, sag dem User warum, und schlage /feature vor.

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.

fix is a skill published in the GitHub repository MichiBl/Claude-Code-Default-Repo (2 stars, last pushed 15d ago), licensed MIT. It adds 98 tokens to every session and 636 once invoked, about $0.0005 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.
