Instinct Apply

You have learned behaviors. Use them.

When To Check

  • Starting a coding task
  • About to use a tool in a pattern you've seen before
  • Making decisions about code style, testing, git

How To Check

# Read all personal instincts
for f in .claude/homunculus/instincts/personal/*.md; do
  [ -f "$f" ] && echo "=== $(basename "$f") ===" && cat "$f" && echo
done 2>/dev/null

# Also check inherited instincts
for f in .claude/homunculus/instincts/inherited/*.md; do
  [ -f "$f" ] && echo "=== $(basename "$f") ===" && cat "$f" && echo
done 2>/dev/null

How To Apply

  1. Read the task/context
  2. Check instinct triggers
  3. If trigger matches, follow the action
  4. Note confidence level - higher confidence = more certain

Instinct Structure

---
trigger: "when [condition]"
confidence: 0.7
domain: "code-style"
---

# Name

## Action
What to do

## Evidence
Why this exists

Confidence Interpretation

  • 0.3-0.5: Tentative. Apply if it feels right.
  • 0.5-0.7: Moderate. Apply unless there's a reason not to.
  • 0.7-0.9: Strong. Apply consistently.
  • 0.9+: Near certain. Always apply.

If Instinct Seems Wrong

When an instinct fires but the action feels wrong for the situation:

  1. Don't apply it blindly
  2. Note the mismatch
  3. This is useful data for the observer

Instincts can be wrong. They're learned from patterns, and patterns have exceptions.

Lightweight Application

Don't read all instincts for every action. Keep relevant ones in working memory.

Quick domain check:

  • Writing code? → Check code-style instincts
  • Running tests? → Check testing instincts
  • Making commits? → Check git instincts
  • Debugging? → Check debugging instincts

Be efficient. Instincts are meant to help, not slow down.

How to use instinct-apply on Cursor

AI-first code editor with Composer

1

Prerequisites

Before installing skills in Cursor, ensure your development environment meets these requirements:

  • Cursor installed and configured on your development machine
  • Node.js version 16.0+ with npm package manager (verify with node --version)
  • Active project directory or workspace where you want to add instinct-apply
2

Execute installation command

Execute the skills CLI command in your project's root directory to begin installation:

$npx skills add https://github.com/humanplane/homunculus --skill instinct-apply

The skills CLI fetches instinct-apply from GitHub repository humanplane/homunculus and configures it for Cursor.

3

Select Cursor when prompted

The CLI will show a list of available agents. Use arrow keys to navigate and space to select Cursor:

◆ Which agents do you want to install to?
│ ── Universal (.agents/skills) ── always included ────
│ • Amp
│ • Antigravity
│ • Cline
│ • Codex
│ ●Cursor(selected)
│ • Cursor
│ • Windsurf
4

Verify installation

Confirm successful installation by checking the skill directory location:

.cursor/skills/instinct-apply

Reload or restart Cursor to activate instinct-apply. Access the skill through slash commands (e.g., /instinct-apply) or your agent's skill management interface.

Security & Verification Notice

We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.

Skills execute code in your development environment. Always verify the publisher's identity, review recent commits, and test in isolated environments before production deployment.

Use Cases

User Story & Requirements Generation

Create detailed user stories, acceptance criteria, and feature specs

Example

Generate user stories for 'password reset feature' with acceptance criteria, edge cases, and test scenarios

Reduce spec writing time by 50%, ensure comprehensive coverage

Competitive Analysis

Research competitors, compare features, identify gaps

Example

Analyze 5 competitor products, create feature comparison matrix, suggest differentiation opportunities

Complete competitive research in 2 hours instead of 2 days

Roadmap Prioritization

Evaluate features using frameworks (RICE, ICE, Kano) and create prioritized backlogs

Example

Score 20 feature ideas using RICE framework, generate prioritized roadmap with rationale

Make data-driven prioritization decisions faster

Stakeholder Communication

Draft PRDs, status updates, and stakeholder presentations

Example

Create executive summary of Q3 roadmap, monthly progress report, feature launch announcement

Save 3-5 hours/week on communication overhead

Implementation Guide

Prerequisites

  • Claude Desktop or compatible AI client
  • Access to product documentation and roadmap tools (Jira, Notion, etc.)
  • Understanding of product management frameworks (RICE, Jobs-to-be-Done, etc.)
  • Stakeholder contact information and communication channels

Time Estimate

30-60 minutes to see productivity improvements

Installation Steps

  1. 1.Install product management skill
  2. 2.Start with user story generation for known feature
  3. 3.Progress to competitive analysis: research 2-3 competitors
  4. 4.Use for roadmap prioritization: apply RICE/ICE scoring
  5. 5.Draft stakeholder communications and refine based on feedback
  6. 6.Build template library for recurring PM tasks
  7. 7.Share effective prompts with product team

Common Pitfalls

  • Not validating competitive research—verify facts before sharing
  • Accepting user stories without involving engineering team
  • Over-relying on frameworks without qualitative judgment
  • Not customizing outputs to company culture and communication style
  • Skipping stakeholder validation of generated requirements

Best Practices

✓ Do

  • +Validate research and competitive analysis with real data
  • +Collaborate with engineering when generating technical requirements
  • +Customize frameworks and templates to your company context
  • +Use skill for first drafts, refine with stakeholder input
  • +Document successful prompt patterns for PM tasks
  • +Combine AI efficiency with human judgment and intuition

✗ Don't

  • Don't publish competitive analysis without fact-checking
  • Don't finalize user stories without engineering review
  • Don't make prioritization decisions solely on AI scoring
  • Don't skip customer validation of generated requirements
  • Don't ignore company-specific context and culture

💡 Pro Tips

  • Provide context: company goals, constraints, customer feedback
  • Ask for alternatives: 'Show 3 ways to prioritize this roadmap'
  • Request stakeholder-specific formatting: 'Executive summary vs. engineering spec'
  • Use skill for 70% generation + 30% customization to company needs

When to Use This

✓ Use When

Use for user story writing, competitive research, roadmap prioritization, stakeholder communication, and PRD drafting. Best for reducing repetitive documentation and research work.

✗ Avoid When

Avoid for strategic product vision (requires deep customer empathy), pricing decisions (needs market and financial expertise), or when face-to-face customer discovery is more valuable than speed.

Learning Path

  1. 1Basic: user stories, feature specs, status updates
  2. 2Intermediate: competitive analysis, prioritization frameworks, PRDs
  3. 3Advanced: product strategy, go-to-market planning, OKR setting
  4. 4Expert: product vision, market positioning, business model innovation
