claude-code

A skill for configuring and troubleshooting Claude Code, Anthropic’s command-line coding tool. It covers the tool’s extensions and settings, including MCP servers, skills, subagents, hooks, permissions, and keybindings.

In plain words
What is it for?
Setting up Claude Code, configuring its extensions and permissions, and troubleshooting its behavior.
Why use it?
Claude Code configuration can involve several files and extension types, so problems are often hard to locate. This provides guidance for choosing and diagnosing those configuration options.

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

claude-code 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 3d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/fetch-claude-code-urls.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Claude Code

Overview

Claude Code is Anthropic's official CLI providing specialized subagents, extensibility (plugins, skills, hooks, MCP), and enterprise features (sandboxing, monitoring). See references/claude-code-urls.md for the full documentation index.

Instructions

Step 0 — Refresh the doc index when fetching docs

If you need to consult the official docs to answer (i.e. you'll hit step 1 or step 2 below), run bash ~/.claude/skills/claude-code/scripts/fetch-claude-code-urls.sh first to rewrite references/claude-code-urls.md from Anthropic's current llms.txt. Skip the refresh for purely conceptual answers or when the existing snapshot is sufficient.

Step 1 — Find the relevant doc

Read references/claude-code-urls.md to find the matching doc. Each line is:

- [Title](https://code.claude.com/docs/en/<page>.md): <description>

Match the user's question to the most relevant entry by title or description.

If no good match is found:

  • Try broad matching (e.g., user asks about "permissions" → check settings.md, permissions.md, plugins.md)
  • If still no match, try WebFetch of the most likely URL from the topic table below
  • If that fails, answer directly from your knowledge and suggest the user check the official docs at https://code.claude.com/docs

Step 2 — Answer the question

For capability/concept questions ("can Claude Code do X?", "what is Y?"):

  • Answer directly from your knowledge if confident
  • Cite the matching URL from claude-code-urls.md for further reading

For implementation/configuration questions (formats, schemas, syntax, step-by-step):

  • WebFetch the .md URL from claude-code-urls.md to get current, accurate details
  • Provide complete working examples with file paths
  • Always cite the source URL
  • If WebFetch fails, answer from your knowledge and note that you're using cached information

Files

What ships with it

2 files 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.

claude-code is a skill published in the GitHub repository berekvolgyipeter/dotclaude (2 stars, last pushed 21d ago), licensed MIT. It adds 92 tokens to every session and 954 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.
