Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00031 | $0.14821 |
| Opus 5.5 | $0.00012 | $0.05928 |
| Sonnet 5.5 | $0.00006 | $0.02964 |
| Haiku 4.5 | $0.00003 | $0.01482 |
Grade C, and why
mastermind-idea scanned grade C with 1 finding 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 2d 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.

Mastermind Idea Domain
This skill is invoked directly via /mastermind:idea, or by /mastermind:master (pack extras — monomind packs add extras).
Extract --monotask flag: If present in $ARGUMENTS, set USE_MONOTASK=true and remove it from $ARGUMENTS. Default: USE_MONOTASK=false.
File mode (default, USE_MONOTASK=false):
Invoke Skill("mastermind:ideate", $ARGUMENTS) immediately — it provides the same research, evaluation, elaboration, and task-decomposition pipeline with file-first storage (docs/ideas/ and docs/tasks/). The rest of this skill is skipped in file mode.
Board mode (USE_MONOTASK=true):
Continue with the full monotask board pipeline below (Steps 3-6).
Inputs
brain_context: BRAIN CONTEXT block (injected by master, or loaded standalone via mastermind-protocol/SKILL.md brain load)prompt: the ideation goal for this runproject_name: monotask space namemode: auto | confirm
Note: the board_id that mastermind:master may pass is its own orchestration board. The idea domain always creates a dedicated ideation board with its own pipeline columns — do not reuse master's board_id.
Complexity Assessment
Assess the prompt to determine execution mode:
Simple (direct execution): Single-answer ideation, one agent:
- "Give me 5 name ideas for this feature"
- "Suggest one pivot angle for this product" → Use a single researcher or content-creator agent. Skip Steps 3–6. Go straight to Step 7 (Brain Write).
Complex (full pipeline): Any of these:
- Product strategy or pivot exploration (multiple angles needed)
- Feature ideation requiring market and user context
- Competitive landscape brainstorm
- Full product vision document → Run Steps 3–6 (Board Setup → Idea Manager → Validation → Elaboration + Tasks).
Standalone Execution (when called without master)
If this skill is invoked directly (not by master):
- Load brain context following mastermind-protocol/SKILL.md Brain Load Procedure (namespace:
idea) - Run intake from mastermind-intake/SKILL.md if prompt is vague
- For complex prompts: run Steps 3–6 below
- At end: follow mastermind-protocol/SKILL.md Brain Write Procedure (namespace:
idea)
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.

mastermind-idea is a skill published in the GitHub repository monoes/monomind (23 stars, last pushed 2d ago), licensed Apache-2.0. It adds 31 tokens to every session and 14,821 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-26.
