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 | $0.00052 | $0.01721 |
| Opus 5 | $0.00026 | $0.00860 |
| Sonnet 5 | $0.00010 | $0.00344 |
| Haiku 4.5 | $0.00005 | $0.00172 |
Grade A, and why
ce-strategy 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 2d 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 — 62 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Product Strategy
The current year is 2026 - use it when dating the document.
ce-strategy writes and maintains its part of STRATEGY.md - the repo-root project document that captures what the project is, who it serves, how it succeeds, and where the team is investing. The file is shared with other tools and people; this skill owns only the sections references/strategy-template.md names. Downstream skills read it when it exists: ce-ideate, ce-brainstorm, and ce-plan for what work is on-strategy; ce-product-pulse for the product name and key metrics; ce-dogfood for the primary persona. Its frontmatter keys and this skill's section headings are the contract those skills parse - keep them for every section this skill authors; a meaning an existing section already carries is merged into it (references/update-run.md).
Done: STRATEGY.md exists at the repo root and the user has seen what will be written and had an edit pass. For a file in this skill's house format, every required section is filled from answers that survived pushback (or explicitly deferred to a linked legacy doc) and the file matches references/strategy-template.md. For a file in any other shape, done is the user-approved minimal edits applied, with the document's shape unchanged. A section the user could not sharpen in two rounds is written as given and named in chat as worth revisiting - a completed run, not a blocked one.
Boundaries
- Anchor, not plan. Strategy is what the product is and why. Features belong in
ce-brainstorm, schedules and prioritization in the issue tracker, implementation plans ince-plan; do not let them creep into the doc, and do not update the tracker or reconcile in-flight work. - The user answers; the repo only grounds the question. Evidence earns a sharper question, never fills in a section. Do not derive the strategy from the repo.
- Short is a feature. Push back on expansion rather than adding sections.
- Record which metrics matter and where they live, not what they read today.
- Meaning is the contract; the shape belongs to whoever created the doc. A file that is solely this skill's -
references/update-run.mdstates the test - is maintained in house format on every write: headings renamed, sections in the template's current order, missing required sections offered; do not treat it as multi-writer merely because the file is shared in principle. A file in any other shape - hand-written, from another tool - is read by meaning and edited in its own shape and idiom: no restructuring into the template, no uninvited frontmatter or headings. Either way a section carrying an author-approved marker (e.g.<!-- <tool>: author-approved 2026-07-10 -->), or a doc the user does not own, is not edited at all - report the conflict, or write a separate file that links to it - and a targeted update preserves every other section's content exactly, its place following that ownership test (a solely-owned file takes the template's order; a multi-writer file is never reordered).references/update-run.mdowns the rest and is a required read before you edit an existing file.
What ships with it
4 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.

ce-strategy is a skill published in the GitHub repository EveryInc/compound-engineering-plugin (24,760 stars, last pushed today), licensed MIT. It adds 52 tokens to every session and 1,721 once invoked, about $0.0003 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.
