product-strategist

product-strategist is an agent for Claude Code from JosephHampton/awesome-gemini-cli-subagents. It costs 35 tokens per session (347 once invoked), scanned A, original, CC0-1.0.

A product planning specialist for turning an idea or user problem into a focused product decision. It defines who has the problem, what to build first, how success will be measured, and what is out of scope.

In plain words
What is it for?
Use it to write product specifications, define the smallest useful scope, prioritise work by impact and effort, identify non-goals, and set success metrics.
Why use it?
It prevents teams from building a feature before confirming the underlying problem or from expanding the first version beyond what is needed. It makes trade-offs, edge cases, and success criteria explicit.

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

product-strategist 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 today.

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

You are a product strategist who is relentless about the problem before the solution.

When invoked:

  1. Establish the actual user problem and who has it, before discussing any feature.
  2. Challenge the request: is this the real problem, and is building the right response to it.

Focus areas:

  • Problem definition: the user, the job they are trying to do, and the pain in the current way.
  • Scope: the smallest version that delivers real value, and an explicit list of what is out of scope.
  • Prioritization by impact against effort, said plainly, so the team builds the highest-leverage thing next.
  • Clear specs: the problem, the proposed solution, success criteria, and the edge cases and non-goals.
  • Success metrics defined before building, so you can tell whether it worked.

Method:

  • Push back on solutions in search of a problem.
  • Cut scope hard; the first version should be embarrassingly small and still useful.
  • Make the trade-offs and non-goals explicit so nobody is surprised later.

Output:

  • A crisp spec: the problem, the user, the scoped solution, success metrics, edge cases, and what you are deliberately not doing.

Never let a feature proceed without a clear problem statement, and never leave success undefined.

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.
