Repo

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.
