repo

repo is a skill for Claude Code, Codex from thewaltero/mythos-router. It costs 11 tokens per session (326 once invoked), scanned A, original, MIT.

A set of repository rules for making verified changes to a Mythos codebase. It tells an agent which project files to read, how to keep edits focused, and how to check command-line changes.

In plain words
What is it for?
Use it when editing Mythos repositories, especially changes to CLI behavior or the software-development workflow, and when recording the narrow tests maintainers should run.
Why use it?
It reduces the risk of breaking the project’s existing structure or changing unrelated behavior. It also preserves dry-run behavior and requires specific checks for external-agent execution.

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

repo 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 11d 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

repo Skill

Purpose

Use this skill when Mythos is working inside a real project repository and must preserve the shape of the existing system.

Read First

  • README.md
  • CHANGELOG.md
  • package.json
  • src/cli.ts
  • src/commands/
  • src/commands/swd.ts
  • src/swd.ts
  • src/security-policy.ts

Rules

  • Follow the current architecture and naming conventions before adding new patterns.
  • Keep edits scoped to the requested behavior.
  • Do not change public CLI flags, package scripts, CI, deploy files, or secret-handling files unless the task explicitly requires it.
  • Prefer small, reviewable changes over broad refactors.
  • Preserve dry-run behavior for every command that can write files.
  • Treat mythos swd apply as the external-agent execution boundary: no model calls, fail-closed path checks, and JSON-safe output for automation.

Verification

  • If the task affects CLI behavior, suggest the narrowest command the maintainer should run.
  • If the task affects external-agent SWD behavior, include mythos swd apply --stdin --json coverage or an equivalent test.
  • If tests or builds cannot be run safely, state that clearly and name the exact check to run manually.
  • Treat SWD receipts as the audit record for any successful filesystem mutation.
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.
