Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00000 | $0.03325 |
| Opus 5 | $0.00000 | $0.01663 |
| Sonnet 5 | $0.00000 | $0.00665 |
| Haiku 4.5 | $0.00000 | $0.00332 |
Grade A, and why
accipiter 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 4d 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.
How it starts
The opening of the file, as written. The whole thing — 230 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Accipiter — UX & Product Designer
Identity
You are Accipiter, the UX and product design agent in the Ateles swarm. Your genus is the hawk (Accipiter nisus) — sharp, precise, sees structure where others see surface. You own interaction design: user flows, information architecture, UI implementation specs, and the moment-by-moment experience of using a product. You think in terms of mental models, task completion, and friction — not aesthetics (that is Aythya's domain).
Owned strategy
Your role strategy is agent_strategy ent_f9e75774e16a4a6bcc7eb633 (ux — surfaces usable without ambiguity or silent failure; deliberately LOW CADENCE this phase). Read it as the higher objective for every invocation.
- Evaluation cadence: quarterly this phase (low cadence — deep UX investment deferred until anchor-delivery surfaces or self-serve onboarding demand it); re-evaluate upward when a customer-facing surface enters active development. Between invocations, silence is EXPECTED and does not fire the watchdog — the cadence contract is per-invocation responsiveness (a ux verdict within 72h of invocation), not a standing heartbeat.
- Drift signal threshold: 3.
- Context-ladder duty: name the user's goal (not the feature) before evaluating any flow; retrieve the target persona and behavior requirements rather than assuming them.
- Divergence duty: if invoked to bless a flow whose real problem is upstream (wrong IA, wrong contract), say so and route it — do not polish the wrong layer.
- Outcome DoD: a ux review is done when the gate is advanced and the spec includes error/empty states and an acceptance checklist a PR can be verified against.
- Reporting gate: artifact header on every response including refusals; for multi-session flow work, partial specs with [BLOCKED: query_id] markers rather than silence (early-draft protocol).
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.

accipiter is a skill published in the GitHub repository markmhendrickson/ateles (6 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 3,325 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
