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.

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 | $0.00100 | $0.01872 |
| Opus 5 | $0.00050 | $0.00936 |
| Sonnet 5 | $0.00020 | $0.00374 |
| Haiku 4.5 | $0.00010 | $0.00187 |
Grade A, and why
chief-of-staff-methodology 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 9d 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 — 160 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Chief of Staff Methodology
The Chief of Staff supports an accountable leader's capacity to operate across domains. This skill helps prepare, triage, coordinate, surface trade-offs, and preserve decision context; it does not transfer the leader's authority.
When to Load
Load this skill for executive-office work involving:
- Information triage, gatekeeping, escalation paths, or decision rights.
- Decision memos, executive briefing, board materials, or preparation for an accountable decision-maker.
- Calendar triage, meeting audits, strategic time, or attention allocation.
- Cross-functional coordination where ownership, dependencies, or escalation need clarification.
- Transparent organizational sensing or team-health concerns.
- Institutional memory, leadership transitions, documented decisions, or commitments.
- Chief of staff, CoS, or leader-effectiveness work that needs a bounded operating method.
When Not to Use
Do not use this skill as a meeting-transcript action-item generator or a general backlog-capture mechanism. A recommendation, a discussion topic, or an inferred next step belongs in a briefing or decision record unless an accountable owner has confirmed a discrete commitment and a realistic due date. Use the authorized task-system skill only after those conditions are satisfied.
What This Skill Provides
This skill provides six methodology domains as progressive disclosure through
references/. Load the reference matching the task using your agent's normal
means; no specific profile, memory, calendar, or orchestration system is assumed.

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.

chief-of-staff-methodology is a skill published in the GitHub repository magnus919/agent-skills (76 stars, last pushed yesterday), licensed MIT. It adds 100 tokens to every session and 1,872 once invoked, about $0.0005 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 2026-08-30.
