+# Workflow Examples
+
+Real-world examples of how preflight catches problems before they cost you tokens.
+
+---
+
+## 1. Catching a Vague Prompt
+
+You type this into Claude Code:
+
+```
+fix the auth bug
+```
+
+Preflight intercepts via `preflight_check` and classifies it as **AMBIGUOUS**:
+
+```json
+{
+  "triage": {
+    "level": "ambiguous",
+    "confidence": 0.85,
+    "reasons": [
+      "No file reference — 'auth' could be JWT, OAuth, session, or middleware",
+      "Vague verb 'fix' without specifying the symptom or expected behavior",
+      "Multiple auth-related files found in project"
+    ],
+    "recommended_tools": ["clarify_intent"]
+  },
+  "clarification": {
+    "questions": [
+      "Which auth component? I found: src/auth/jwt.ts, src/auth/oauth.ts, src/middleware/session.ts",
+      "What's the symptom — login failing, token expiring, 403 errors?",
+      "Should this fix include tests?"
+    ]
+  }
+}
+```
+
+**What you do:** Answer the clarification, get a precise fix in one pass.
+
+---
+
+## 2. Multi-Step Task Planning
+
+You type:
+
+```
+refactor the user model to support teams and update all the API routes
+```
+
+Preflight classifies this as **MULTI-STEP** and suggests a plan:
+
+```json
+{
+  "triage": {
+    "level": "multi-step",
+    "confidence": 0.92,
+    "reasons": [
+      "Two distinct operations: schema change + API route updates",
+      "Schema change has downstream effects on queries, types, and tests",
+      "Cross-cutting concern: 'all API routes' is unbounded scope"
+    ],
+    "recommended_tools": ["scope_work", "clarify_intent"]
+  },
+  "scope": {
+    "suggested_steps": [
+      "1. Define the Team model and User→Team relation in schema",
+      "2. Generate and run migration",
+      "3. Update User type definitions (shared-types if cross-service)",
+      "4. Update API routes that read/write User (list specific files)",
+      "5. Update tests for affected routes",
+      "6. Run full test suite"
+    ],
+    "estimated_files": 12,
+    "risk": "medium — schema migration affects production data"
+  }
+}
+```
+
+**What you do:** Tackle it step by step instead of one giant prompt.
+
+---
+
+## 3. Cross-Service Contract Awareness
+
+You type:
+
+```
+change the User type to add a teamId field
+```
+
+With `related_projects` configured in `.preflight/config.yml`, preflight detects **CROSS-SERVICE** impact:
+
+```json
+{
+  "triage": {
+    "level": "cross-service",
+    "confidence": 0.88,
+    "reasons": [
+      "User type is defined in contracts (shared across auth, billing)",
+      "Matched related project aliases: auth, billing, types"
+    ],
+    "recommended_tools": ["search_contracts", "clarify_intent"]
+  },
+  "contracts": {
+    "affected": [
+      { "project": "auth", "file": "src/types/user.ts", "usage": "JWT payload includes User fields" },
+      { "project": "billing", "file": "src/api/subscription.ts", "usage": "Reads User.tier for pricing" },
+      { "project": "types", "file": "src/index.ts", "usage": "Canonical User interface" }
+    ],
+    "warning": "Changing User shape requires updates in 3 downstream services"
+  }
+}
+```
+
+**What you do:** Update all consumers in one coordinated pass instead of breaking downstream services.
+
+---
+
+## 4. Correction Pattern Detection
+
+After the third time Claude edits the wrong test file, preflight learns the pattern:
+
+```
+update the tests
+```
+
+```json
+{
+  "triage": {
+    "level": "ambiguous",
+    "confidence": 0.95,
+    "reasons": [
+      "Correction pattern detected: 3 past corrections for 'tests' → user meant integration tests in tests/integration/, not unit tests in __tests__/"
+    ],
+    "recommended_tools": ["clarify_intent", "check_patterns"]
+  },
+  "patterns": {
+    "matched": [
+      {
+        "pattern": "When user says 'tests' without qualifier, they mean tests/integration/",
+        "corrections": 3,
+        "last_seen": "2025-01-15"
+      }
+    ]
+  }
+}
+```
+
+**What you do:** Preflight pre-fills the right context so you don't burn tokens on the same mistake again.
+
+---
+
+## 5. Trivial Prompts Pass Through
+
+Not everything needs guardrails. Mechanical tasks skip checks entirely:
+
+```
+commit this with message "fix typo in README"
+```
+
+```json
+{
+  "triage": {
+    "level": "trivial",
+    "confidence": 0.99,
+    "reasons": ["Matches trivial command: commit"],
+    "recommended_tools": []
+  }
+}
+```
+
+No friction for simple tasks.
+
+---
+
+## 6. Using Scorecards to Improve Over Time
+
+After a coding session, generate a scorecard:
+
+```
+generate a scorecard for this session
+```
+
+Preflight analyzes your prompts and returns a 12-category breakdown:
+
+```
+Category                  Score   Notes
+─────────────────────────────────────────────────
+Prompt Specificity        7/10    3 prompts lacked file refs
+Context Reuse             9/10    Good use of prior context
+Scope Control             5/10    2 unbounded "update all" prompts
+Correction Rate           6/10    4 corrections in 28 prompts
+Session Hygiene           8/10    Reasonable session length
+...
+
+Overall: 7.1/10
+Estimated waste: ~4,200 tokens (12% of session)
+Top suggestion: Add file paths to prompts — would have prevented 3 clarification rounds
+```
+
+**What you do:** Track your score over weeks. Teams using preflight typically see a 20-30% reduction in token waste within the first month.

+
+## Setup Recap
+
+1. Install: `claude mcp add preflight -- npx -y preflight-dev-serve`
+2. (Optional) Copy config: `cp -r examples/.preflight .preflight`
+3. Start coding — preflight runs automatically on every prompt
+
+That's it. No behavior changes required — preflight intercepts and advises in the background.
