Project Context Skill (PRE-FLIGHT MANDATORY)

USAGE: Run this before EVERY prompt to load relevant context from past work.

@project-context [your upcoming task/question]

---

What This Skill Does

1. Searches Graphiti for similar past work (bugs, patterns, solutions)
2. Recommends the right vibe to load (backend/frontend/qa/infra)
3. Surfaces relevant context (gotchas, files, past decisions)
4. Provides actionable starting points based on institutional knowledge
5. Auto-improves by documenting its own effectiveness

---

Phase 1: Parse Intent

Extract from user's prompt:

• Domain (backend, frontend, testing, devops, appium)
• Task type (feature, bug, refactor, debug, test, spec)
• Key entities (agent, device, UI component, database, API)
• Spec-kit phase (if applicable: research, plan, implement, retro)

Examples:

• "Fix agent stalling on consent dialog" → backend, debugging, agent, appium
• "Build navigation component" → frontend, feature, UI
• "Write E2E test for run flow" → testing, E2E, run
• "Research real-time updates" → frontend, spec-discovery, sse
• "Plan SSE implementation" → frontend, spec-planning, architecture
• "Implement task 1 from spec-002" → frontend, spec-implementation

---

Phase 2: Search Graphiti & Get MCP Recommendations

Adjust searches based on intent:

If spec-related (research, plan, implement):

// Search for past specs
const pastSpecs = await search_memory_nodes({
  query: "spec [domain] [feature-type]",
  group_ids: ["screengraph"],
  max_nodes: 10
});

// Search for implementation patterns
const patterns = await search_memory_nodes({
  query: "[domain] implementation patterns",
  group_ids: ["screengraph"],
  max_nodes: 10
});

If task-related (standard work):

// Search 1: Broad domain patterns
const domainPatterns = await search_memory_nodes({
  query: "[domain] patterns and best practices",
  group_ids: ["screengraph"],
  max_nodes: 10
});

// Search 2: Specific past work
const pastWork = await search_memory_nodes({
  query: "[specific task keywords]",
  group_ids: ["screengraph"],
  max_nodes: 10
});

// Search 3: Known gotchas
const gotchas = await search_memory_facts({
  query: "[technology/component] issues and workarounds",
  group_ids: ["screengraph"],
  max_facts: 10
});

Always get MCP recommendations:

const mcpRecs = await suggest_mcps({
  task: "[user's task description]",
  include_examples: false  // Keep it brief
});

Extract from results:

• ✅ Similar past solutions
• ✅ Related files to check
• ✅ Known gotchas to avoid
• ✅ Relevant architectural decisions
• ✅ Recommended MCPs to use

---

Phase 3: Recommend Vibe & MCPs

Based on domain, recommend vibe to load:

If task involves...	Load this vibe
Backend API, agent, database, Encore	backend_vibe
Frontend UI, Svelte, routing, components	frontend_vibe
E2E tests, Playwright, integration tests	qa_vibe
CI/CD, Task commands, MCP servers, automation	infra_vibe
Multiple domains simultaneously	backend_vibe + frontend_vibe (explicitly state both)

Also include MCP recommendations from screengraph-orchestrator:

The orchestrator provides:

• Prioritized list of MCPs to use (graphiti always first)
• Specific tools to call within each MCP
• Usage examples and integration guidance
• Workflow suggestions tailored to the task

---

Phase 5: Auto-Improvement

After task completion, document effectiveness:

// At end of session, ask user:
// "Did the context I provided help? What was missing?"

// Then document:
await add_memory({
  name: "Project Context Effectiveness - [Date]",
  episode_body: `
    [Tags: meta, project-context, self-improvement]
    
    **Task**: [What user asked for]
    **Context Provided**: [Summary of what I surfaced]
    **Outcome**: [Was it helpful? What was used? What was missing?]
    **Improvements**: [How to search better next time]
    
    **Patterns Discovered**:
    - [New pattern recognized]
    - [Connection between past work items]
    
    **Search Query Effectiveness**:
    - Queries used: [list]
    - Hit rate: [how many results were relevant]
    - Suggested improvements: [better keywords, different approach]

Usage Examples

Example 1: Backend Debugging

User says:

@project-context Fix agent hanging on device connection

Skill response:

## 🎯 Context Loaded for: Agent Device Connection Issue

### 📚 Relevant Past Work
- BUG-011: Appium shell stall - Learned to check WebDriver session health
- BUG-015: Privacy consent dialog stall - Must check for modals before policy execution
- Agent recovery patterns - Documented in device-check.ts

### 📁 Files to Check
- backend/agent/nodes/setup/EnsureDevice/device-check.ts - Device health checks
- backend/agent/nodes/setup/EnsureDevice/node.ts - Connection logic
- backend/agent/machine/AgentMachine.ts - State transitions

### ⚠️ Known Gotchas
- Appium sessions can timeout silently (set explicit timeouts)
- First-run consent dialogs block automation (check before starting)
- WebDriver commands fail without proper error surfacing

### 🎭 Recommended Vibe
**Load `backend_vibe`** for this task.

Use: encore-mcp for introspection, backend-debugging skill for systematic approach

### 🚀 Suggested Starting Point
1. Use encore-mcp to check latest agent state and run events
2. Add checkpoint logs in device-check.ts to narrow hang location
3. Verify WebDriver session is still alive
4. Check for modal dialogs blocking UI hierarchy

### 📖 Additional Resources
- Skill: backend-debugging (10-phase procedure)
- MCP: encore-mcp (query database, check traces)

Example 2: Frontend Feature

User says:

@project-context Build real-time run status component

Skill response:

## 🎯 Context Loaded for: Real-time Run Status Component

### 📚 Relevant Past Work
- Run page uses SSE for real-time updates (frontend/src/routes/runs/[runId]/+page.svelte)
- Svelte 5 runes pattern: $state for reactive data
- Event stream integration documented in run service

### 📁 Files to Check
- frontend/src/routes/runs/[runId]/+page.svelte - Existing SSE implementation
- backend/run/encore.service.ts - Event stream endpoint
- backend/run/stream.repo.ts - Run events query

### ⚠️ Known Gotchas
- SSE connections must handle browser reconnect gracefully
- Svelte 5 runes: Use $state() for reactivity, not let/const
- Event stream order: subscribe BEFORE fetching initial state (avoid race condition)

### 🎭 Recommended Vibe
**Load `frontend_vibe`** for this task.

Use: svelte MCP for autofixer, playwright for testing

### 🚀 Suggested Starting Point
1. Review existing SSE pattern in run detail page
2. Create component with $state() for status
3. Subscribe to run_events stream
4. Handle reconnection and error states
5. Test with playwright browser inspection

### 📖 Additional Resources
- Context7: svelte/svelte (Svelte 5 runes, $state, $effect)
- Skill: frontend-development (Svelte 5 patterns)

Example 3: Testing

User says:

@project-context Write E2E test for agent run flow

Skill response:

## 🎯 Context Loaded for: Agent Run E2E Test

### 📚 Relevant Past Work
- Existing E2E test: tests/e2e-run.spec.ts - Full run flow coverage
- Backend testing with encore test (includes all subscriptions)
- Integration test pattern: backend/agent/tests/metrics.test.ts

### 📁 Files to Check
- frontend/tests/e2e-run.spec.ts - Existing E2E pattern
- backend/agent/tests/metrics.test.ts - Backend test structure
- .claude-skills/backend-testing_skill/SKILL.md - Testing workflow

### ⚠️ Known Gotchas
- MUST import all subscriptions in encore test (agent, artifacts, graph)
- Appium + device must be running for integration tests
- E2E tests: Use playwright browser MCP instead of manual inspection
- Frontend E2E: Wait for SSE events, not just HTTP responses

### 🎭 Recommended Vibe
**Load `qa_vibe`** for this task.

Use: playwright MCP for frontend, encore-mcp for backend verification

### 🚀 Suggested Starting Point
1. Review existing e2e-run.spec.ts for pattern
2. Identify user flow to test
3. Write Playwright test with browser snapshots
4. Verify backend state with encore-mcp queries
5. Add to smoke test suite if critical path

### 📖 Additional Resources
- Skill: webapp-testing (Playwright-first approach)
- Skill: backend-testing (Encore test patterns)
- MCP: encore-mcp (verify backend state during test)

Search Query Patterns (Self-Improvement)

Track what works:

User Intent	Effective Queries	Hit Rate	Refinement Needed
"Fix agent stall"	"agent state machine error", "device connection timeout"	High	Add "recovery patterns"
"Build component"	"Svelte 5 component patterns", "UI real-time updates"	Medium	Add specific component type
"Write test"	"E2E testing patterns", "integration test structure"	High	No change
"Debug database"	"database migration", "schema constraints"	Low	Add "SQL errors"

Document in Graphiti:

await add_memory({
  name: "Project Context Query Effectiveness - [Month]",
  episode_body: `
    [Tags: meta, project-context, search-queries]
    
    **Effective Query Patterns**:
    - Agent issues: "agent state" + "error handling" + "recovery"
    - UI components: "[framework] component" + "real-time" + "patterns"
    - Testing: "[test-type] testing patterns" + "structure"
    
    **Query Refinements Needed**:
    - Database issues: Add "constraint violations" to generic "database" queries
    - Performance: Add "optimization" + "bottleneck" keywords
    
    **New Patterns Discovered**:
    - When user mentions "stall/hang", always search for "timeout" and "session"
    - When user mentions "build X", search for both "X component pattern" and "X integration"
