idea-lab

idea-lab is a skill for Claude Code, Codex from NickCrew/Claude-Cortex. It costs 18 tokens per session (370 once invoked), scanned A, original, MIT.

A concept-selection method that scores ideas by impact, user appeal, and effort before choosing one to test.

In plain words
What is it for?
Use it to compare concept cards, rank options, select a one-day spike, and define verification steps.
Why use it?
It makes prioritisation more explicit when several ideas compete for limited time and resources.

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

idea-lab 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

/collaboration:idea-lab

Use this when you need many angles fast and want to leave with 1-day experiments queued.

Inputs

  • Topic or problem statement
  • Constraints (time, platform, compliance, budget)
  • Any existing assets to reuse

Steps

  1. State the timebox (default 15m).\n2. Capture goal, success signals, constraints, assets.\n3. Generate 5–7 distinct concepts with Wow-Factor, Feasibility (S/M/L), Dependency to check.\n4. Select Top 3 to test today; assign a 1-day experiment to each.\n5. Seed Task view or hand off to /ctx:plan.

Output Template

### Problem / Goal
### Success Signals
### Constraints
### Existing Assets
### Options (table)
| Concept | Wow-Factor | Feasibility | Dependency to Check |
|---------|------------|-------------|---------------------|
### Top 3 Experiments
### Next Steps

Resources

  • See modes/Idea_Lab.md for tone cues.\n- Pair with /ctx:plan after choosing the top experiment.\n- Use /collaboration:assumption-buster first if the problem is sticky.

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.
