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 | $0.01083 |
| Opus 5 | $0.00032 | $0.00541 |
| Sonnet 5 | $0.00013 | $0.00217 |
| Haiku 4.5 | $0.00006 | $0.00108 |
Grade A, and why
okhp3-cowork-daily-execution-brief 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 8d 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.

Create a credible day plan, not an aspirational task dump.
Scope
| In scope | Out of scope |
|---|---|
| A bounded personal workday, calendar conflicts, commitments, and next actions | Changing a calendar, sending messages, task-system updates, or judging productivity |
Host contract
- Target: Microsoft Copilot Cowork personal custom skill.
- Portable core: reconcile supplied priorities and time constraints into a short execution plan.
- Cowork adaptation: use calendar, email, and files only when available within the user's permissions and agreed session scope.
- Evidence: documented Cowork behavior; no live Cowork run for this package.
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 weekly review for a week-level reconciliation and meeting prep for an event-specific brief. This skill owns only today's realistic plan.
Required input and safe outcomes
Confirm the date, working hours, source scope, and any non-negotiable meetings
or deadlines. Return NEEDS INPUT for an unclear day or priority set,
INSUFFICIENT PERMISSION for inaccessible context, and NOT SUPPORTED when
the host cannot read the selected source type.
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.
