harness:ideate

A structured brainstorming command that creates and ranks possible product ideas using project strategy when available. It records each idea's premise, audience, complexity, risks, expected impact, confidence, and effort in a Markdown file.

In plain words
What is it for?
Use it to generate candidate ideas, examine objections, score trade-offs, and save a ranked ideation document.
Why use it?
It turns an open-ended brainstorming topic into a documented comparison, so ideas can be evaluated before implementation.

Made for: Claude Code.

Per session 99 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 553 The whole file, excluding the scripts and references it only reads on demand.

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

harness:ideate 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.

What it actually says

Phases:

  • ground: Read STRATEGY.md if present at repo root (grounding); read the focus argument; confirm the topic with the user.
  • generate: Produce N candidate ideas with per-idea fields (premise, persona, complexity, key risk, impact, confidence, effort).
  • critique: For each idea identify the strongest objection; user picks which objections to answer.
  • rank: Score by (impact × confidence) ÷ effort using a 1/2/3 mapping for low/medium/high; apply strategy-alignment as a bounded tiebreaker bonus when STRATEGY.md is present.
  • write: Persist the ranked artifact to docs/ideation/[slug]-YYYY-MM-DD.md (kebab-case slug ≤30 chars, 6-char hash suffix on collision).

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.
