+
+## Unique Learnings to Extract
+
+### 1. mgrep Tool (Token Optimization)
+- 50% token reduction vs grep/ripgrep
+- Implementation details to document
+- Comparison benchmarks to validate
+
+### 2. pass@k and pass^k Metrics
+- Formal verification approach:
+  - pass@k: At least one of k attempts succeeds
+  - pass^k: All k attempts must succeed
+  - Example: k=3 → 91% pass@k, 34% pass^k
+- Application: Measure skill effectiveness empirically
+
+### 3. Hookify Plugin Workflow
+- Conversational hook creation (describe need → JSON generated)
+- Lowers barrier vs manual JSON writing
+- Pattern: Natural language → structured config
+
+### 4. Sandboxed Subagents
+- Tool restriction per agent (security-reviewer can't Edit)
+- Prevents accidental destructive actions
+- Implementation: Define `tools: [Read, Grep]` in agent config
+
+### 5. Cascade Method (Multi-Instance)
+- Manage multiple Claude instances: "Sweep left to right, oldest to newest"
+- Focus on 3-4 tasks max
+- Prevents context switching overhead
+
+### 6. Stop Hook Pattern
+- Auto-summarization at session end (vs per-message)
+- Captures: successes, failures, unexplored paths
+- Feeds into reusable skills
+
+### 7. Skill Creator from Git History
+- Extract patterns from actual commits
+- Plugin or local implementation
+- Pattern: `git log` → skill definition
+
+### 8. Context-Aware MCP Management
+- 20-30 MCPs configured, <10 enabled per project
+- Reduces context window pressure (200k → 70k effective)
+- Strategy: Enable per task, not globally
+
+### 9. Iterative Retrieval Pattern
+- 3-cycle max for subagent context clarification
+- Corrects subagent limitation (lack of orchestrator context)
+- Flow: Query → Clarify → Revisit → Output
+
+### 10. Two-Instance Kickoff Pattern
+- Instance 1 (Scaffolding): Project structure + config
+- Instance 2 (Research): Deep integration + docs
+- Prevents context mixing early in project
+
+---
+
+## Risks & Limitations
+
+### 1. Opinionated Stack
+- **Risk**: Heavy Go-specific patterns, Zed editor focus
+- **Mitigation**: Author acknowledges "modify for your stack"
+- **Impact**: Medium (requires adaptation)
+
+### 2. Node.js Dependency
+- **Risk**: Not all teams use Node.js
+- **Mitigation**: Manual installation available (bash-compatible)
+- **Impact**: Low (Node.js widely adopted)
+
+### 3. Learning Curve
+- **Risk**: Advanced patterns assume Claude Code familiarity
+- **Mitigation**: Shortform guide covers foundations
+- **Impact**: Medium (our guide bridges this gap)
+
+### 4. Plugin System Maturity
+- **Risk**: New distribution model, potential bugs
+- **Mitigation**: Manual installation fallback
+- **Impact**: Low (community testing rapid)
+
+### 5. Maintenance Dependence
+- **Risk**: Single primary author (affaan-m)
+- **Mitigation**: 3.8k forks ensure continuity, MIT license
+- **Impact**: Low (community can fork-maintain)
+
+---
+
