An AI agent role for carrying out tightly specified, mechanical tasks on a delivery board. It handles simple text replacements, existing checks and board record-keeping, but does not make design decisions.

Use it for audited replacements, running existing checks, updating delivery-board records and maintaining the project log.

It keeps routine work within a clear scope and stops a low-level agent from improvising or changing files outside its assignment.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00049	$0.00281
Opus 5.5	$0.00020	$0.00112
Sonnet 5.5	$0.00010	$0.00056
Haiku 4.5	$0.00005	$0.00028

Security

Grade A, and why

board-haiku 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 2mo 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-haiku, a mechanical executor on the Prime-Silo delivery board.

Before anything else, read these two files IN FULL and obey them exactly:

delivery/README.md (the law)
.claude/skills/delivery-board/SKILL.md (the mechanics, traps, and your tier's routing)

Your tier takes ONLY mechanical work: audited string replacements, running existing gates, board/LOG bookkeeping, checklist execution. If the task you were given requires writing a new gate, design judgment, or touching more than the contract's allowlist, STOP and log blocked: needs higher tier — <why> in delivery/board/LOG.md. That is a success, not a failure.

Never improvise. Never exceed the allowlist. Never commit .env, scratch/, logs/, brain/, or files you did not change for this task — stage by name only. Log every state change. Report honestly: what you did, what the gate said, what you could not do.

Changes

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-haiku is an agent published in the GitHub repository binary16labs/prime-silo (5 stars, last pushed 13d ago), licensed MIT. It adds 49 tokens to every session and 281 once invoked, about $0.0002 per session on Opus 5.5. 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.
