Idea Darwin Engine — an automated idea iteration system that evolves raw ideas through structured competition and selection. Imports ideas from ideas.md, structures them into scored cards, then runs iterative rounds of deepening, derivation, crossbreeding, critique, and validation to surface high-potential ideas. Use /idea-darwin to trigger. This skill should also trigger whenever the user mentions "run a round", "iterate ideas", "idea pool", "idea scoring", "idea status", "brainstorm iteration", "evolve my ideas", "rank my ideas", or "idea pipeline". Even if the user doesn't explicitly say /idea-darwin, use this skill whenever the task involves structuring ideas from a file, scoring and ranking ideas, or running any kind of systematic idea iteration or selection process.
A round-based idea iteration system that treats ideas as competing organisms — scoring, selecting, crossing, and evolving them through structured rounds to surface the strongest concepts.
The metaphor is Darwinian selection: ideas that score well survive and evolve; weak ideas get flagged for the user to decide on; crossbreeding produces novel offspring. This prevents the common failure mode of brainstorming where all ideas stay equally vague forever.

State transitions are recommended by the system based on scores and action results, but the user always has final say.
Scoring System
6 Scoring Dimensions (1–10 each)
Dimension
Weight
Meaning
Novelty
0.10
Is there a genuine breakthrough, or just repetition?
Feasibility
0.20
Is this technically, resource-wise, and path-wise achievable?
Value
0.20
How much impact would this create if successful?
Logic
0.20
Is it internally consistent, with no obvious gaps?
CrossPotential
0.10
How likely is this to spark something new when combined with other ideas?
Verifiability
0.20
Can we design an experiment or minimum validation path?
Three-Layer Scoring Formula
The scoring is layered so that each layer captures a different strategic lens — Survival measures standalone quality, Development measures growth potential, and Priority blends both with recency and diversity bonuses to prevent the pool from stagnating.
List all initial card summaries, scores, and suggested next steps
Write to rounds/round-000.md
Present results to user
Display a summary table of all cards (ID, title, score, suggested action)
Inform the user about stimuli.md and how to use it:
stimuli.md has been created in the project root. Every N rounds, the system randomly selects up to 5 enabled entries as external stimuli to break mental ruts.
You can edit this file anytime to add/modify/disable entries. Each entry follows this format:
Wait for user confirmation before entering the formal round cycle
Round Execution Flow
When the user runs /idea-darwin round, execute these 9 steps strictly in order:
Step 1: Import New Ideas
Every round starts by checking the default idea document: read the file pointed to by source.ideas_file in config.yaml
Compare the default ideas.md against existing cards to identify new additions
For new ideas: tag → generate card → initial scoring
New ideas are marked stage: seed and receive the NewIdeaBoost
This is a mandatory pre-step for every round — the system must not loop only over existing cards while ignoring incremental additions to the source file
Step 2: Update Relationship Graph
Based on all cards' tags and content, compute inter-idea similarity
Distribute slots according to max_ideas_per_round:
25% for newly pooled ideas
30% for deepening high-priority ideas
20% for deriving from high-potential ideas
15% for cross experiments
10% for disruption / random exploration
Select ideas by Priority Score descending. Each idea gets at most max_actions_per_idea actions.
Step 5: Decide Actions
For each selected idea, assign actions based on the state machine (see table above).
When the state machine is insufficient, use score-driven rules:
High Novelty + Low Verifiability → deepen
High Novelty + High CrossPotential → cross
High Value + Low Feasibility → critique + refine
High Feasibility + Low Logic → deepen
High duplication → merge
Step 6: Execute Actions
Process each selected idea in turn. Refer to references/actions.md for detailed execution specs, and references/prompts.md for prompt templates.
Execution flow per idea:
Read the full card
Follow the corresponding prompt template for the action type — think deeply
Produce structured output:
Updated card content
New derived ideas (auto-assign IDs, update parent_ids/child_ids on both sides)
Score changes
Discovered risks
Suggested next actions
Write the updated card file
Newly derived ideas also require full card generation and initial scoring.
Step 7: Validate and Deduplicate
Run two-layer validation on all newly produced ideas:
Layer 1 (Fatal flaw check): Logical contradiction? No real demand? Completely infeasible? Near-duplicate?
Layer 2 (Value judgment): Worth continuing? What next? Biggest risk?
Validation failure → mark validated: false, lower priority, report to user
The user decides whether to dormant or remove — the system only recommends
Run similarity check across the entire pool and merge near-duplicates
Step 8: Generate Round Report
Write to rounds/round-XXX.md, including:
Ideas processed this round and actions executed
Newly produced idea summaries
Top 5 score changes (up/down)
Ideas that failed validation (require user decision)
Recommended priorities for next round
If disruption round: which external stimuli were used, which innovation frameworks applied
Step 8.5: Output Round Briefing
After all file updates are complete, output a round briefing directly in the conversation (not written to file) so the user can understand the full picture without opening any files. Format:
text
## Round N Briefing
### Actions Taken
| ID | Title | Action | Key Output |
|---|---|---|---|
| IDEA-XXXX | ... | deepen/derive/cross/critique/... | One-line summary |
### Card Changes
| ID | Title | Score Change | State Change | Notes |
|---|---|---|---|---|
| IDEA-XXXX | ... | Priority X.XX→X.XX | seed→exploring | Reason for change |
### New Ideas (Detail)
For each newly produced idea this round:
#### IDEA-XXXX: [Title]
- **Source**: [cross/derive/stimulus] from IDEA-XXXX + IDEA-XXXX
- **Core Question**: [one paragraph]
- **Key Insight**: [what's most valuable about this idea]
- **Initial Score**: Priority X.XX (Survival X.XX / Development X.XX)
- **Current Tension**: [biggest unresolved question]
- **Suggested Next Step**: [deepen/derive/cross/critique + specific direction]
### Current Rankings
| Rank | ID | Title | Priority | Stage |
|---|---|---|---|---|
### Next Round Preview
- [Suggested priority actions]
- [Whether a disruption round is coming soon]
### Decisions Needed
> List key decisions the user needs to make this round. Each item **must include the idea's full title** (not just the ID) along with context and suggested options.
> Examples:
> 1. **IDEA-0002 "Learn Coding Agent Tutorial Site" overlaps with IDEA-0004 "Progressive Unboxing Pedagogy"** — Merge or reposition? Suggestion: [...]
> 2. **IDEA-0006 "Auto-Diagnostic Thread" failed validation** — Dormant, pivot, or keep observing?
> 3. **IDEA-0003 "Thermal Management Ontology" downgraded** — Accept downgrade from ontology to structured Excel as first step?
>
> If no user decisions are needed this round, write "No decisions needed this round."
This briefing is the primary interface between the user and the system — keep it complete and readable. The "Decisions Needed" section is the most important interaction point: the system should clearly list decision items with recommendations, rather than leaving the user to discover issues from reports.
Step 9: Save State
Update all modified card files
Increment current_round in config.yaml
Update next_idea_id
Update reports/leaderboard.md (Top 10 rankings)
External Stimuli and Disruption Rounds
Every trigger_every_n_rounds rounds (default 3), external stimuli are introduced in a "disruption round." The purpose is to prevent the idea pool from converging on a local optimum by forcing fresh perspectives.
External Stimulus File (stimuli.md)
stimuli.md lives in the project root. It is created during initialization and maintained by the user. Format:
markdown
## Industry Trend: Embodied AI Accelerating to Production
- status: enabled
- Embodied AI moving from lab to production line in 2026, robot operating costs down 60%
## Tech Shift: Unified Multimodal Model Architecture
- status: enabled
- Vision, language, and code unified into single models, API paradigm changing
## Contrarian View: SaaS Is Dead
- status: disabled
- Open-source + self-hosted deployments replacing traditional SaaS subscriptions
Each entry: ## heading + status field + content description
enabled = participates in random selection; disabled = skipped
Users can add, edit, or toggle entries at any time
The system only reads this file — never writes to it
Disruption Round Mechanics
Shuffle priorities: Give low-priority but novel ideas a chance to surface
Distant cross: Force crossbreeding between ideas with non-overlapping tags
External stimuli: Randomly select up to 5 enabled entries from stimuli.md
Assumption reversal: For top-scoring ideas, ask "What if the core assumption is wrong?"
Innovation frameworks: Apply SCAMPER / First Principles / Analogical Transfer / Constraint Reversal / Extreme User Perspective
Each round also reserves wildcard_budget_ratio (default 10%) of slots for non-optimal-path exploration.
Dormancy and Wake
/idea-darwin dormant IDEA-XXXX
Read the card, set stage to dormant
Record reason and round number in the card's "Dormancy Log"
The idea will no longer be selected for deepen/derive, but still participates in cross and similarity matching
/idea-darwin wake IDEA-XXXX
Read the card, restore stage to the pre-dormancy state (inferred from history, typically exploring)
Update the "Dormancy Log"
The system never auto-dormants any idea. Only the user can make that call.
/idea-darwin status
Read config.yaml and all cards, then output:
Current round number
Total ideas in pool (broken down by state)
Top 10 rankings (by Priority Score descending)
What was processed in the most recent round
Suggested next steps
Key Constraints
ideas.md is read-only: Never modify the user's ideas.md
IDs never recycle: Numbers are never reused under any circumstance
Branch limit: Each idea can derive at most 2–3 children per round
Per-round dedup: Similarity check is mandatory before a round concludes
User control: The system never auto-dormants or removes ideas — only recommends
Structured output: Every action must produce structured results
Consistent card format: All cards strictly follow assets/card-template.md
Traceable reports: Every round report must contain a complete operation log
Reference Files
references/actions.md: Detailed specs and use cases for each standard action
references/prompts.md: Prompt templates for each action
