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

son-of-anton AGENTS.md 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 9d 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.

The opening of the file, as written. The whole thing — 40 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Repo Rules

  • If the user says triage, use the soa-pr-review skill at .agents/skills/pr-review/SKILL.md.
  • If the user says /soa quality-control or /soa qc, use the soa-quality-control skill at .agents/skills/quality-control/SKILL.md. This is the post-phase fix-and-record lane — not a delivery-orchestrator command and not a replacement for /soa tao or closeout.
  • For phase work, read docs/template/overview/start-here.md and docs/template/delivery/delivery-orchestrator.md first, then surface the orchestrator path before coding.
  • Use the soa-son-of-anton-ethos skill at .agents/skills/son-of-anton-ethos/SKILL.md automatically when executing any approved multi-ticket phase/epic or standalone (non-ticketed) PR — including when the user says execute, begin, start, deliver, implement, continue, resume, run, drive, carry, work on, or explicitly mentions son of anton / son-of-anton ethos. That skill owns execution mechanics, stop conditions, polling, and review outcome recording.
  • For new product feature-set expansion, phase shaping, or epic decomposition: run a planning pass and use soa-grill-me before accepting any plan. Developer approval of ticket decomposition is required before implementation.
  • Prefer bun run deliver --plan ... over ad hoc implementation. The delivery orchestrator reads orchestrator.config.json at repo root; see docs/template/delivery/delivery-orchestrator.md. For orchestrated ticket work, the handoff under .agents/delivery/<plan-key>/handoffs/ is required input alongside plan and ticket docs.
  • New product phase/epic starts only after developer-approved ticket decomposition. Docs-only, cleanup-only, and tooling-only changes skip this. Smaller bounded changes may ship as standalone PRs using the orchestrator's triage-standalone path.
  • Final merge of stacked PR slices requires developer approval. Close completed phases with bun run closeout-stack --plan <plan-path>.
  • PR titles: Conventional-Commit-style subject + active ticket suffix (e.g. [P3.02]) when the ticket is clear from branch/docs/diff. Apply even when the user did not type pr.

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.
