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 | $0.00023 | $0.04388 |
| Opus 5 | $0.00012 | $0.02194 |
| Sonnet 5 | $0.00005 | $0.00878 |
| Haiku 4.5 | $0.00002 | $0.00439 |
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 4d 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 — 336 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Brainstorming Skill
You are running the Forge brainstorming workflow. Your job is to turn a user's idea into one or more concrete specification files with R-numbered requirements and testable acceptance criteria.
Inputs
The user provides one of:
- A topic (plain text describing what they want to build)
--from-codeflag (analyze the existing codebase to generate specs)--from-docs PATHflag (read documents from PATH, extract requirements)
Workflow
Phase 1: Complexity Detection
Before asking questions, determine the scope of the user's request.
Analyze the topic (or codebase/documents) and classify complexity:
| Level | Signals | Question Count |
|---|---|---|
| Simple (single feature, few files, clear scope) | Bug fix, small enhancement, single endpoint, UI tweak | 3-4 questions |
| Medium (multi-component, new feature with defined scope) | Multiple files across directories, needs tests, some cross-component work | 5-7 questions |
| Complex (multi-domain, architectural decisions, cross-repo) | New system/subsystem, security-sensitive, unfamiliar tech, multi-repo | Decompose into sub-projects first, then 5-7 questions per sub-project |
Hard cadence bounds for every run: minimum 3 questions, maximum 7 questions before the proposal stage. If a complex project seems to need more, decompose into sub-projects and run a separate bounded Q&A per sub-project rather than exceeding 7 in a single run.
Scoring heuristics (each signal adds 1 point):
- Multiple files across 2+ directories: +1
- Cross-component dependencies: +1
- Cross-repo work needed: +2
- Architectural decisions required: +2
- Security-sensitive code: +1
- New system or subsystem: +2
- Unfamiliar technology or novel approach: +1
- Multi-domain decomposition needed: +2
Score 0-3 = Simple, 4-7 = Medium, 8+ = Complex.
Tell the user the detected complexity and how many questions you will ask. Example: "This looks like a medium complexity project. I'll ask 6 questions to nail down the spec, one at a time."
What ships with it
1 file 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.

brainstorming is a skill published in the GitHub repository LucasDuys/forge (55 stars, last pushed 1mo ago), licensed MIT. It adds 23 tokens to every session and 4,388 once invoked, about $0.0001 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 2026-08-30.
