What it does

Audit Config is an agent skill from ethereum/execution-specs. Check whether repository guidance and skills are still accurate.

Its SKILL.md is about 490 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with Ethereum. The repository describes itself as: Specification for the Execution Layer. Tracking network upgrades. The licence is CC0-1.0.

Example prompts

  • “/audit-config”

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Verify File Paths
  2. Verify CLI Commands
  3. Verify Code Patterns
  4. Verify Fork List
  5. Verify Docs References

What it can do on your machine

Read from SKILL.md and the folder at commit dc6d1a5. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • uv

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use uv, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Audit Config loads about 488 tokens when it runs. Until then it costs about 19 tokens; SKILL.md has 225 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~19
When it runs · the whole SKILL.md, loaded when a task matches
~488

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Audit Config

Periodic verification skill to prevent AGENTS.md and skills from going stale. Run this manually to check freshness (e.g., after a major refactor, before a release, or when onboarding).

Checks to Perform

1. Verify File Paths

Check that every file path or directory referenced in AGENTS.md and .agents/skills/*/SKILL.md still exists. Report any broken references.

Confirm that CLAUDE.md is a symlink to AGENTS.md. Confirm that every .agents/skills/<name>/ directory has a corresponding .claude/skills/<name> symlink that points back to it, and that there are no orphaned Claude skill links.

2. Verify CLI Commands

Run --help on referenced commands and confirm mentioned flags still exist:

  • uv run fill --help
  • uv run ethereum-spec-new-fork --help
  • uv run ethereum-spec-lint --help
  • uv run checklist --help
3. Verify Code Patterns

Spot-check code patterns mentioned in skills against actual code:

  • Does op_implementation dict exist in the latest fork's vm/instructions/__init__.py?
  • Does PRE_COMPILED_CONTRACTS exist in the latest fork's vm/precompiled_contracts/mapping.py?
  • Does the Ops enum exist in vm/instructions/__init__.py?
  • Does FORK_CRITERIA or equivalent exist in the latest fork's __init__.py?
4. Verify Fork List

Check that the fork order and default branch mentioned in AGENTS.md match reality by inspecting src/ethereum/forks/ and git branch configuration.

5. Verify Docs References

Confirm that docs/ paths referenced in skills still exist:

  • docs/writing_tests/
  • docs/writing_tests/opcode_metadata.md
  • docs/writing_tests/checklist_templates/
  • docs/filling_tests/

Output

Produce a summary with:

  • Current: references that are still valid
  • Stale: references that need updating, with suggested fixes

Can I use Audit Config in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add ethereum/execution-specs --skill audit-config -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/audit-config, .gemini/skills/audit-config, .github/skills/audit-config and .opencode/skills/audit-config in your project.

What does Audit Config need to run?

Going by SKILL.md and its folder, Audit Config needs the command-line tools its instructions call (uv).

Does Audit Config access the network?

SKILL.md contains no URLs. Its commands use uv, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
