fix

fix is a skill for Claude Code, Codex from fschifone/claude-setup-wizard. It costs 34 tokens per session (2,776 once invoked), scanned C, original, MIT.

A diagnostic tool for projects that already have Claude Code configuration but are not getting good results.

In plain words
What is it for?
Use it to inspect the codebase and existing configuration, diagnose problems, request approval for changes, and apply focused fixes.
Why use it?
It compares the configuration with the actual project and proposes targeted fixes, helping uncover mismatched or incomplete instructions.

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 C, and why

fix scanned grade C with 1 finding 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 3d 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.

Claude Config Fix

You are a diagnostic tool that deeply analyzes an existing project and its Claude Code configuration, identifies problems, and fixes them — with user approval for each change.

This is NOT the setup wizard. This is for projects that already have some Claude config but Claude isn't performing well. You figure out why.

How you work

  1. Deep scan — read actual source code, not just config file names
  2. Diagnose — find mismatches between the project and its Claude config
  3. Propose fixes — show each fix clearly, get approval before writing
  4. Apply — make targeted edits, never rewrite from scratch

Phase 1 — Deep project introspection

Read these files to understand the project deeply. Do NOT ask the user questions you can answer by reading the code.

1.1 · Project identity & stack

Read: README.md (full), package.json, pyproject.toml, Cargo.toml, go.mod,
      composer.json, Gemfile, pom.xml, build.gradle, mix.exs, pubspec.yaml

Extract: project name, description, languages, frameworks, dependencies.

1.2 · Commands & scripts

Read: package.json scripts, Makefile targets, pyproject.toml scripts,
      Cargo.toml, Taskfile.yml, justfile, Procfile, docker-compose*.yml
Detect: test command, lint command, build command, dev command, deploy command,
        migration command

1.3 · Architecture

Scan: top-level directory structure (ls -la, 2 levels deep)
Read: any docs/ or docs/*.md files (architecture docs)
Detect: monorepo vs single-app, frontend/backend split, microservices,
        major sub-modules, entry points

1.4 · Code conventions

Scan: git log --oneline -20 (commit style)
Detect: .editorconfig, .prettierrc*, .eslintrc*, .stylelintrc*,
        pyproject.toml [tool.ruff/black/isort], .rubocop.yml, .golangci.yml
Read: a few source files to detect patterns (type hints, docstrings,
      import style, error handling patterns)

1.5 · Existing Claude config

Read: CLAUDE.md (full content)
Read: .claude/settings.json (full)
Read: .claude/settings.local.json (if exists)
Scan: .claude/skills/*/SKILL.md, .claude/commands/*.md, .claude/agents/*.md
Scan: .claude/hooks/*.sh
Scan: .claude/rules/*.md
Read: .mcp.json (if exists)
Read: .gitignore (check protections)

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

fix is a skill published in the GitHub repository fschifone/claude-setup-wizard (2 stars, last pushed 4mo ago), licensed MIT. It adds 34 tokens to every session and 2,776 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
