ce-strategy

A product-strategy writing skill that creates or updates STRATEGY.md, a project document describing what a product is, who it serves, and where it is going.

In plain words
What is it for?
Use it when starting a product, changing direction, defining a roadmap, or adding strategy information to an existing code repository.
Why use it?
It gives later planning and idea work a shared description of the product and its priorities. This reduces decisions based on missing or outdated context.

Token cost

What it costs to keep this loaded

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.

Security

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 in ce-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.md states 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.md owns 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.

Changes

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.
