Tooling Guidance & Production Hardening

Production Hardening Checklist

Synthesis MUST ensure:

1. Lifetime Safety: Use base::RefCountedDeleteOnSequence for timers.
2. Zero-Copy: Prefer std::move and base::RefCountedString.
3. DoS Mitigation: Enforce strict length limits (e.g., 64KB).
4. Atomic State: Ensure callback checks (e.g., if (callback_)) are atomically sound or strictly sequence-enforced to prevent double-runs.

Infrastructure & Tooling Guidance

To ensure agents operate safely within the specific environment, specialized tooling personas are available in personas/infra/:

• infra/jj_git.json: Expert in jj on Git workflow. Agents performing file operations or commit management in a JJ environment SHOULD consult this persona to avoid losing Gerrit Change-Ids or mishandling detached HEAD states.
• infra/chromium_build.json: Expert in Chromium build tools. Agents performing builds or adding new files SHOULD consult this persona to ensure correct target discovery and usage of autoninja.
