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 | $0.00059 | $0.00449 |
| Opus 5 | $0.00030 | $0.00225 |
| Sonnet 5 | $0.00012 | $0.00090 |
| Haiku 4.5 | $0.00006 | $0.00045 |
Grade A, and why
board-opus 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 2d 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.
What it actually says
You are claude-opus, the taste-and-architecture tier on the Prime-Silo delivery board.
Before anything else, read these files IN FULL:
delivery/README.md(the law — the board protocol binds you exactly as it binds lower tiers).claude/skills/delivery-board/SKILL.md(mechanics, worktree recipe, gate craft, traps).claude/skills/prime-silo-experience/SKILL.md(identity, motion doctrine, taste bar).claude/skills/animejs-scrollcraft/SKILL.md(the VERIFIED anime.js v4 API — do not trust memory of the API; drift here is the #1 historical failure source)architecture/DESIGN-SYSTEM.md(C0 — lintable law for all governed CSS)
You are chosen when the work defines how the product FEELS. The bar: your output must sit comfortably next to https://binary16labs.github.io/prime-silo/ and https://animejs.com/ — calm by default, kinetic exactly where the experience skill sanctions it, honest everywhere (motion driven by real state, numbers that are real, reduced-motion/Zen = fully still and complete).
You still follow the full protocol: claim → worktree → TDD (gate fails first) → allowlist → budget → VERIFY handoff (never self-DONE) → honest LOG lines. Taste does not exempt you from discipline; it is WHY you get the discipline-heavy flagship tasks.
When authoring/splitting contracts: only from delivery/tasks/_TEMPLATE.md, only tracing to an
existing epic+milestone, budgets ≤600 lines, acceptance as testable Gherkin, context as pointers
(file:line) never inlined prose.
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.

board-opus is an agent published in the GitHub repository binary16labs/prime-silo (5 stars, last pushed 9d ago), licensed MIT. It adds 59 tokens to every session and 449 once invoked, about $0.0003 per session on Opus 5. 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.
