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 | $0.00130 | $0.01379 |
| Opus 5.5 | $0.00052 | $0.00552 |
| Sonnet 5.5 | $0.00026 | $0.00276 |
| Haiku 4.5 | $0.00013 | $0.00138 |
Grade A, and why
personal-chief-of-staff 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 26d 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 — 114 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Personal Chief of Staff
Help the user review current evidence, correct their sources, and choose what comes next. Existing systems remain authoritative; keep the review in the conversation until the user approves specific source changes.
Route the current message
Read source-access.md before the first source access or write on every path. Load other resources only when the matched path below names them. Resolve the message in this order:
- Visible review action decisions: bind approvals, edits, deferrals, and skips to the exact displayed bundle and its originating mode. A bare number is usable only when the visible context identifies its action. Load that mode's reference and action-application.md, plus crm-companion.md for a relationship-derived effect. Perform the current pre-write checks and readback without new review discovery. Load source-bindings.md only when the approved target cannot otherwise be resolved; stop that action if its binding remains unresolved.
- Answers to a Frontier Round: interpret numbers against the most recent question round and continue the mode and phase that asked it, with the resources that run loaded.
- Source setup and management: when asked to establish, list, add, update, or remove review source mappings, or when replying to a binding preview, load source-bindings.md and resolve the requested mapping operation with the user. Existing mappings go directly to that operation without restarting the category interview. This path opens no mode; finish it under Finish standalone setup.
- A new review: select one mode below. An explicit mode wins. Load source-bindings.md and resolve the private map before the mode's source retrieval. Before retrieval, also load review-reasoning.md, the mode reference, and review-bundle.md. Load action-application.md before proposing the first action, and crm-companion.md when the companion is available to Wind-down or Weekly or evidence makes a person materially relevant.
- Cross-source context for another workflow: load source-bindings.md for only the roles that caller's decision needs. Return the retrieved context with its Source Access Audit and leave the narrower operation with the caller. This path opens no mode.
What ships with it

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.

personal-chief-of-staff is a skill published in the GitHub repository jrgilbertson/the-rookery (12 stars, last pushed yesterday), licensed MIT. It adds 130 tokens to every session and 1,379 once invoked, about $0.0005 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.
