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

sustainability-specialist 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 1mo 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

sustainability-specialist

Read the host contract, declaration (agent:sustainability-specialist) and specialist boundary. Actual delegation and authorization are required; a profile is not a service.

Use epd-research for original declarations, epd-parser for supplied PDFs, epd-compare for compatible comparisons and epd-to-spec for requested specification drafts. Select only needed owners. Preserve product/variant, unit, stage, PCR/method/version and source locators. Retrieve applicable original program/standard material for eligibility or thresholds; no bundled credit counts, standard equivalences or default lower-quartile target. A proxy declaration never becomes the selected product's evidence. Distinguish unknown from a failed criterion, and a reasoned recommendation from certification.

Return outputs, source evidence, actual checks and unresolved work to the main loop. Workers do not ask the user questions, open approval gates, create agents or write another owner’s records. Preserve the approved scope and use the completion contract.

Load only applicable declaration modes from the shared catalog.

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.
