Muscle Memory Recognition

Expert in identifying when manual work should become automated scripts.

Capabilities

• Recognize repetitive task patterns
• Identify heavy-lifting operations suitable for scripting
• Evaluate automation ROI (time saved vs creation effort)
• Recommend muscle creation with language/framework
• Connect new muscles to trifecta files

When to Use This Skill

• Same task performed manually 3+ times
• Multi-step operations with consistent patterns
• Error-prone manual processes
• Time-consuming operations during conversation
• Complex file manipulation or validation

Muscle Identification Signals

Signal	Strength	Example
Repetition (3+ occurrences)	🔴 Strong	"Run these 5 commands again"
Multi-step sequence (4+ steps)	🔴 Strong	"Create folder, copy files, update config, validate"
Error-prone operations	🟡 Medium	"Format all files, check for inconsistencies"
Time sink in conversation	🟡 Medium	Operations taking >30 seconds
Cross-session recurrence	🔴 Strong	"We did this last session too"
Validation patterns	🟡 Medium	"Check all X for Y property"
Batch operations	🟡 Medium	"Do X to all files matching pattern"

Anti-Signals (Don't Automate)

Signal	Reason
One-time operation	ROI too low
Requires human judgment each time	Can't be scripted reliably
Simple single command	Already optimal
Rapidly changing requirements	Script would be constantly outdated
Security-sensitive operations	Manual review required

Muscle Creation Decision Matrix

IF (repetition >= 3) AND (steps >= 2):
    → CREATE MUSCLE (high value)

IF (repetition >= 2) AND (error_prone = true):
    → CREATE MUSCLE (reliability value)

IF (time_per_execution > 1min) AND (expected_uses >= 5):
    → CREATE MUSCLE (time value)

IF (steps >= 5) AND (pattern_consistent = true):
    → CREATE MUSCLE (complexity value)

ELSE:
    → DEFER (observe for more signals)

Language Selection Guide

Comparison Matrix

Factor	PowerShell	Node.js (JS/TS)	Python
Windows native	✅ No runtime needed	❌ Requires Node	❌ Requires Python
Cross-platform	⚠️ Works but quirks	✅ Excellent	✅ Excellent
File operations	✅ Native cmdlets	✅ Good with fs	✅ Good with pathlib
JSON handling	⚠️ ConvertFrom-Json	✅ Native	✅ Native
Pipeline syntax	✅ Excellent	❌ Requires chaining	❌ Requires chaining
Async operations	⚠️ Jobs (awkward)	✅ Native async/await	✅ asyncio
npm ecosystem	❌ No	✅ Full access	❌ No (pip instead)
Type safety	❌ No	✅ TypeScript	⚠️ Type hints
Startup speed	✅ Fast	⚠️ ~200ms Node init	⚠️ Similar
VS Code integration	⚠️ Limited	✅ Extension API	❌ No

Task-to-Language Mapping

Task Pattern	Recommended	Reason
File validation / scanning	PowerShell	Get-ChildItem, pipeline, regex built-in
JSON config manipulation	Node.js	Native JSON, better object handling
CLI tools with nice UX	TypeScript	chalk, inquirer, spinners
npm library usage	Node.js	Direct access to ecosystem
Quick one-off scripts	PowerShell	No build step, immediate
Cross-platform / heir-critical	Node.js	Portable across systems
API calls with types	TypeScript	fetch, async/await, type safety
Text/Markdown transforms	Node.js	String methods, regex literals
Audits with reporting	PowerShell	Format-Table, pipeline filtering

Decision Algorithm

IF (validation OR audit OR file-scanning):
    → PowerShell (pipeline + cmdlets shine here)

IF (JSON manipulation OR npm libraries needed):
    → Node.js (native JSON + ecosystem access)

IF (CLI tool with user interaction):
    → TypeScript (type safety + UX libraries like chalk)

IF (quick prototype OR Windows-only):
    → PowerShell (no setup required)

IF (cross-platform required OR heir-critical):
    → Node.js (portable, same behavior everywhere)

Muscle Naming Convention

{action}-{target}.{ext}

Examples:
- validate-skills.ps1
- sync-architecture.js
- normalize-paths.ps1
- gamma-generator.js
- brain-qa.ps1

Integration Checklist

When creating a new muscle:

• Create script in .github/muscles/
• Add to inheritance.json (master-only or inheritable)
• Update referencing trifecta files (skills/instructions/prompts)
• Add to TRIFECTA-CATALOG.md if part of trifecta
• Document invocation in referencing files
• Test from heir context if inheritable

Example Prompts

• "We've done this 3 times now, should we script it?"
• "This validation takes forever, can we automate it?"
• "I keep making mistakes with these steps"
• "What muscles exist for this type of task?"
• "Should this be a muscle or stay manual?"

Output Format

When identifying a muscle opportunity:

## 💪 Muscle Opportunity Detected

**Task**: [Description of repetitive/heavy task]
**Signal**: [Which signal triggered this]
**Estimated Value**: [Time saved × Expected uses]

### Recommendation
- **Action**: Create muscle / Defer / Keep manual
- **Language**: [Recommended language]
- **Name**: [Suggested muscle name]
- **Location**: `.github/muscles/{name}`
- **Inheritance**: master-only / inheritable

### Implementation Notes
