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 | $0.00081 | $0.00667 |
| Opus 5 | $0.00041 | $0.00333 |
| Sonnet 5 | $0.00016 | $0.00133 |
| Haiku 4.5 | $0.00008 | $0.00067 |
Grade A, and why
codexkit-executive-brief-writer 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 4d 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.

Executive Brief Writer
Purpose
Produce a short, decision-oriented brief that respects executive attention and surfaces the real choice.
When to use
- A leader needs a one-page read before making a call.
- A team must compare options and recommend one path.
- A complex issue needs a short decision memo instead of a long report.
When not to use
- The task is only to summarize text with no recommendation.
- The audience needs a detailed technical appendix instead of an executive brief.
Inputs
- business question or decision to make
- context, evidence, and constraints
- options considered and current recommendation
- known risks, tradeoffs, and deadline
- intended audience and tone
Procedure
- State the decision question in one sentence.
- Distill the situation and why it matters now.
- Compare the real options, including the cost of doing nothing.
- Make one recommendation and support it with evidence.
- Surface the top risks, assumptions, and required decisions.
- End with clear next steps, owners, and timing.
Output
- headline and decision ask
- situation summary
- options with tradeoffs
- recommended path
- key risks and assumptions
- next steps and owners
Definition of done
- The brief can be read in under five minutes.
- A leader can tell what decision is being requested.
- Tradeoffs and risks are explicit, not hidden in narrative.
Examples
- "Write an executive memo for approving a new vendor contract versus building internally."
- "Turn this messy project update into a one-page decision brief for the COO."
Quality Criteria
- All claims reference specific frameworks, standards, or quantifiable data
- Content matches the stated audience's expertise level
- Recommendations are actionable — each includes a concrete next step
- No unsupported assertions or generic filler language
Verification (4C)
| Check | Question |
|---|---|
| Correctness | Do referenced frameworks and standards match their official definitions? |
| Completeness | Are all key concepts covered without significant gaps for the stated audience? |
| Context-fit | Would this be useful for someone new to this domain, or is it too advanced/too basic? |
| Consequence | If a stakeholder acted on this immediately, what could they misinterpret? |
What ships with it
1 file 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.
