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

review 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 24d 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.

Review

Review evidence, not intent. Do not modify files.

During Explore or Build, do not invoke Git. Review the changed paths recorded in TASKS.md against SPEC.md, acceptance criteria, and verification output. Git status, diffs, staging, and branch comparisons are reserved for $ship.

Selective independent review

Independent review is a configured Build decision, not a default panel or runtime. The canonical $autonomous-build route delegates review when any configured trigger matches; it must not narrow routing to risk alone. Before deciding, validate and read the selected profile from .codex/capabilities.toml with python scripts/codexicon.py capabilities --json; do not invent thresholds or substitute values from another profile. Delegate the read-only reviewer profile when any configured trigger matches:

  • the assessed task or change risk is in required_risk_levels;
  • the changed-file count is greater than or equal to changed_files_threshold;
  • the change has a public API, security, architecture, or test-complexity signal and the corresponding review_on_public_api, review_on_security, review_on_architecture, or review_on_test_complexity flag is true.

The trigger is selective: trivial low-risk work is exempt when it is below the configured file threshold and none of the enabled signals is present. The primary agent remains the one sequential Build writer and still performs the normal self-review and focused checks. This is not a background runtime or an automatic publication mechanism. An independent review is exactly one read-only reviewer pass and one correction round; the reviewer may inspect files and evidence but must not edit, run publication, or expand Git, deployment, credential, external-write, or other Ship authority.

For a triggered review, completion evidence must carry a stable finding ID and one disposition for every finding: accepted, fixed, rejected, or not_applicable. Each finding gets exactly one of those dispositions. A reviewer PASS has no actionable findings; it does not grant publication authority or replace the task's required verification.

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.
