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 5.1 | $0.00023 | $0.00202 |
| Opus 5.5 | $0.00009 | $0.00081 |
| Sonnet 5.5 | $0.00005 | $0.00040 |
| Haiku 4.5 | $0.00002 | $0.00020 |
Grade A, and why
brainstorm-csk 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 1mo 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
/brainstorm-csk
Argument: $ARGUMENTS
Delegate to the @agent-planner-csk agent applying the brainstorm skill. For an under-defined ask:
- Restate the real goal separately from the requested solution.
- Generate 2–4 genuinely different directions (include a cheap/minimal one); give each its trade-off.
- Surface assumptions + open questions; mark which are blocking.
- Ask the user to choose WITH explicit numbered options; log the rejected directions + why.
Write a long exploration to docs/DISCOVERY.md; return the option headings + the chosen direction (token-budget).
Do NOT write code — this is discovery. Once a direction is chosen, hand off to /plan-csk (spec-planning).
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.

brainstorm-csk is a command published in the GitHub repository byerlikaya/claude-starter-kit (24 stars, last pushed 29d ago), licensed MIT. It adds 23 tokens to every session and 202 once invoked, about $0.0001 per session on Opus 5.5. 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.
