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 | $0.00063 | $0.01333 |
| Opus 5 | $0.00032 | $0.00666 |
| Sonnet 5 | $0.00013 | $0.00267 |
| Haiku 4.5 | $0.00006 | $0.00133 |
Grade A, and why
okhp3-cowork-meeting-prep 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.

Prepare the room before the meeting starts: the decision, evidence, participants, and open questions should be visible in one short brief.
Scope
| In scope | Out of scope |
|---|---|
| Briefs, agendas, pre-work, and reviewable communication drafts for one agreed event | Calendar changes, invites, cancellations, sends, posts, or access to unrelated meeting material |
Host contract
- Target: Microsoft Copilot Cowork personal custom skill.
- Documented host adaptation: Cowork can work with the user's calendar, organizational files, email, Teams, OneDrive, and SharePoint only within the user's existing permissions; sensitive calendar or communication actions require approval.
- Evidence status: documented host capability; no live Cowork run for this package.
- Portable core: synthesize a supplied agenda, participants, and material into a decision-oriented brief.
- Cowork-specific behavior: retrieve only the event and work context the user selected or the host makes available for the session.
Activation boundary and handoff
- Interactive and automation boundary: Use interactively by default. A scheduled or event-driven run may produce a draft only; it must not send, post, schedule, share, create, modify, move, rename, or delete anything.
- Approval policy: Require a current-session, target- and content-specific confirmation before an external action. This is this skill's policy, not a claim that Cowork enforces the same granularity.
- Portable fallback: Outside verified Cowork retrieval, use only material
supplied or attached by the user. Otherwise return
NEEDS INPUT; do not search local, tenant, or connector context. - Host availability: Cowork custom skills are not supported on mobile.
Return
NOT SUPPORTEDon an unavailable surface. A handoff guides work after activation; it cannot prove exclusive host skill selection. - Handoff: Use daily execution brief only for the day's plan and project context pack for broader multi-source orientation.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

okhp3-cowork-meeting-prep is a skill published in the GitHub repository OKHP3/skillz (3 stars, last pushed today), licensed MIT. It adds 63 tokens to every session and 1,333 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings.
