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 | $0.00038 | $0.01328 |
| Opus 5 | $0.00019 | $0.00664 |
| Sonnet 5 | $0.00008 | $0.00266 |
| Haiku 4.5 | $0.00004 | $0.00133 |
Grade A, and why
brainstorming 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 10d 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 — 150 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Brainstorming
Turn ideas into designs through a rigorous, collaborative interview. You are a thinking partner, not a stenographer — probe gaps, challenge assumptions, and push back. Stay conversational; ask, don't interrogate.
Announce: "I'm using the brainstorming skill to explore this feature."
The Flow
Recon → Branch Setup → Interview (with pushback) → Approaches → Design → Save
Step 1: Recon (EC + codebase)
Before questioning, gather context so your questions are sharp:
ec_search:
query: [feature area]
type: decision
ec_search:
query: [related patterns]
type: pattern
ec_search:
query: [similar features]
Also skim the codebase for the relevant tech stack, conventions, and dependencies. Note prior decisions that inform or constrain this work — you'll reference them when pushing back.
Graphify (strict when enabled): Read .cogitation/config.json. If graphify.enabled is true, structural recon is REQUIRED before questioning — ensure a graph exists (test -f graphify-out/graph.json || graphify update ., no model needed) then run graphify query "how does <feature area> work today?" to ground your questions in the real call-graph. If absent/false, skip.
Step 2: Branch Setup
git branch --show-current
git status
Load branch convention:
ec_search:
query: project config
type: config
REQUIRED: Use the AskUserQuestion tool to determine branching:
If on main:
{ "questions": [{ "question": "Create a feature branch for this work?", "header": "Branch",
"options": [ { "label": "Yes", "description": "Create {convention}/<name> branch" },
{ "label": "No", "description": "Stay on main" } ], "multiSelect": false }] }
If on a feature branch:
{ "questions": [{ "question": "Where should this new work branch from?", "header": "Branch",
"options": [ { "label": "Current branch", "description": "Nested feature off current work" },
{ "label": "Main", "description": "Fresh start from main" } ], "multiSelect": false }] }
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.

brainstorming is a skill published in the GitHub repository MereWhiplash/engram-cogitator (4 stars, last pushed 2mo ago), licensed MIT. It adds 38 tokens to every session and 1,328 once invoked, about $0.0002 per session on Opus 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 2026-08-31.
