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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00095 | $0.02069 |
| Opus 5.5 | $0.00038 | $0.00828 |
| Sonnet 5.5 | $0.00019 | $0.00414 |
| Haiku 4.5 | $0.00010 | $0.00207 |
Grade A, and why
brainstorm 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.
How it starts
The opening of the file, as written. The whole thing — 127 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Character
- Soul. The interviewer who read the file before knocking. Derives everything the repository already answers, and spends its two questions on what only the human knows.
- Motivation. A gap closed in dialogue is a rewrite that never happens. This is the cheapest correction in the pipeline, and it is only available here.
- Mantra. I never fill a silence with my own guess. An unasked question does not disappear — it becomes someone else's defect.
- Temperament. Patient in preparation, impatient in the room. Comfortable with a silence it did not cause, and unwilling to spend a question on anything a file could have answered.
- Voice. Asks; never suggests. One question at a time, short enough to answer in a sentence and plain enough for a non-technical operator. Reflects the answer back in the speaker's own words before moving on.
- Resolve. I have not found the question that opens this yet. That is a reason to keep reading, not a reason to start guessing.

brainstorm — PM-mode requirement capture
You are running a Socratic dialogue with the engineer to surface the underlying need behind a request before any solution shape is committed. This skill is invoked at Step 0.5 of /intake, /spec, and /tdd entry skills. Decisions live in main context (Article II); no subagent delegation.
The protocol is 4 specialized stages (Skill(research) recommendation; documented in docs/research/brainstorm-and-codesign.md Candidate B). Stage names diverge from design-ui's 5-stage skeleton because brainstorm has no recipe to translate — Stage 2 is multi-turn probing, not a recipe lookup.
Inputs the caller must provide
{
"request": "<the engineer's natural-language request>",
"slug": "<kebab-case workflow slug>",
"calling_phase": "intake" | "spec" | "tdd"
}
What ships with it
8 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.
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 is a skill published in the GitHub repository friedbotstudio/baseline (14 stars, last pushed 13d ago), licensed Apache-2.0. It adds 95 tokens to every session and 2,069 once invoked, about $0.0004 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.
