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 | $0.00058 | $0.00352 |
| Opus 5.5 | $0.00023 | $0.00141 |
| Sonnet 5.5 | $0.00012 | $0.00070 |
| Haiku 4.5 | $0.00006 | $0.00035 |
Grade A, and why
executive-briefing 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 1mo 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.
What it actually says
Executive Briefing
Core Workflow
- Identify the audience, decision horizon, period, business context, and intended use of the brief.
- Gather supplied signals: metrics, customer issues, revenue, product, delivery, finance, hiring, risks, decisions, and open actions.
- Separate facts, assumptions, risks, decisions needed, and recommended focus.
- Prioritize what changed, what matters, what needs attention, and what can wait.
- Keep the brief short enough for an executive to review quickly.
- End with decisions requested, owner follow-ups, and unresolved questions.
Safety Rules
- Do not invent metrics, commitments, customer facts, board facts, or financial figures.
- Do not turn weak signals into confident strategic conclusions.
- Flag missing data, stale context, and unverified claims.
- Require review before external, board, investor, customer, legal, or finance use.
Deliverable Shape
For executive briefings, provide:
- Context and time period
- Top changes since last review
- Priority issues and opportunities
- Key metrics or signals
- Decisions needed
- Risks and mitigations
- Owner actions
- Open questions
References
- Read
references/executive-briefing-checklist.mdwhen preparing a CEO, founder, owner, leadership, or weekly executive brief.
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.

Draft or refine IDD-ready GitHub issues, roadmap issues, and sub-issues before the normal IDD execution loop begins.

Use when opening an analiz task for the system-architect - the required fields, what the criteria may say, and what the description must hand over.
