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 5.1 | $0.00047 | $0.00675 |
| Opus 5.5 | $0.00019 | $0.00270 |
| Sonnet 5.5 | $0.00009 | $0.00135 |
| Haiku 4.5 | $0.00005 | $0.00068 |
Grade A, and why
a1-decision-memo 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.
How it starts
The opening of the file, as written. The whole thing — 41 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Decision Memo
Organize complex source material into a clear internal document without flattening important detail or inventing a decision or action.
Entry Contract
Accept a request when the user supplies notes, a report, correspondence, analysis, a chronology, meeting material, or another source pack and wants one internal document that helps a named or inferable reader decide, approve, respond, or understand current status.
A completed report, legal analysis, financial model, or project plan may be consumed as source material. Producing that specialist analysis is outside this skill. A request to choose a strategy without source-supported options or criteria is also outside scope.
Route one compact send-ready messenger or ordinary business-email message for an existing business contact to a1-business-message; retain Decision Memo for a standalone layered, reference-ready internal decision, response, or awareness/status document whose supporting detail, including chronology as applicable, must remain inspectable, even when it is delivered by email. The communication goal alone—inform, decide, approve, or respond—does not choose the owner; artifact shape does. When the format is unnamed and both shapes remain materially plausible, use Business Message when the complete job fits one compact send-ready message, and ask one artifact-shape question only when choosing depth or structure would materially change the result.
Editing or reviewing an already selected finished memo belongs to a1-copy-editing. A public article belongs to a1-article-writing; a media announcement belongs to a1-press-release.
For a mixed request, state the boundary and stop before organizing or deciding any part.
Marketing Context is optional. Read only the first existing repository context in this order: .agents/marketing-context.md, then .claude/marketing-context.md when the canonical path is absent, then root marketing-context.md when both earlier paths are absent. Read no lower-priority context after selecting one. Continue without context when none exists.

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.
