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.

SkillSpector: 2 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Excessive Agency · line 6 Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.Fix: Remove the model/provider override or disclose it prominently and require explicit operator approval before invoking an external coding CLI or billed model.
- medium Excessive Agency · line 428 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
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 | $0.00030 | $0.03637 |
| Opus 5.5 | $0.00012 | $0.01455 |
| Sonnet 5.5 | $0.00006 | $0.00727 |
| Haiku 4.5 | $0.00003 | $0.00364 |
Grade A, and why
project-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 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 — 488 lines — stays where its author put it; the contents beside it link to each section on GitHub.
When To Use
- Starting a new project without clear requirements
- Exploring problem space before specification
- Need to compare multiple approaches systematically
- Validating project feasibility and scope
- Documenting decision rationale for stakeholders
- Need to clarify the core problem being solved
When NOT To Use
- Requirements and specification already exist (use
Skill(attune:project-planning)instead) - Refining existing specs (use
Skill(attune:project-specification)instead) - Project scope is well-defined (jump to
/attune:project-init) - Mid-project pivots (use
Skill(attune:war-room)for strategic decisions)
Integration
With superpowers:
- Delegates to
Skill(superpowers:brainstorming)for Socratic method - Augments with project-specific patterns
- Uses project brainstorm templates
Without superpowers:
- Standalone questioning framework
- Project-focused ideation patterns
- Structured output templates
War Room Integration (REQUIRED):
- After Phase 3 (Approach Generation), automatically invokes
Skill(attune:war-room) - All brainstorming context passed to War Room for expert deliberation
- War Room provides multi-LLM pressure testing and synthesis
- Only bypassed for Type 2 decisions (RS ≤ 0.40) with explicit user confirmation
Brainstorming Framework
Phase 1: Problem Definition
Socratic Questions:
- What problem are you solving?
- Who experiences this problem?
- What makes this problem worth solving now?
- What happens if this problem isn't solved?
- What existing solutions have been tried?
- Who reads what this project produces, and what do they already know? Name a role specific enough to point at someone who holds it.
Question 6 sets the audience tier that every document this
project generates inherits: newcomer, practitioner, expert,
or a one-line persona. Ask it here rather than at drafting
time, where the answer gets guessed to keep the draft moving.
Tier table and follow-up questions: scribe:slop-detector module

What ships with it
2 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.

project-brainstorming is a skill published in the GitHub repository athola/claude-night-market (343 stars, last pushed yesterday), licensed MIT. It adds 30 tokens to every session and 3,637 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 2026-09-03.

brainstorming
You MUST use this before any creative work (features, products, content, strategy, systems, or behavior changes). Start by classifying what we’re brainstorming, then run thorough one-question-at-a-time discovery, propose 2–3 approaches, and converge on a validated plan/spec.
learn
Use this skill when the user wants intellectual understanding — learning how or why something works, not getting a task done or soliciting Claude's judgment. Trigger for: Explicit learning requests: teach, explain, ELI5, walk me through, quiz me, flashcards, "I'm rusty on"; definitions ("what is X") Terse concept…
llmtornado-tutorial-generator
Generates comprehensive code tutorials on LlmTornado API formatted for Medium publication with examples, explanations, and best practices.

grill
A requirements-clarification workflow for requests that are vague, incomplete, or open to several interpretations. It checks available information first, asks one decision-focused question at a time, and records agreed terms and decisions in project documents.
toy
Build a world the human drives until how a thing behaves is intuitive. Use when the user needs to hold how something behaves and reading has not made it intuitive.
