Navigator SOP Creator Skill

Create Standard Operating Procedures (SOPs) - reusable documentation for processes, integrations, debugging solutions, and workflows.

When to Invoke

Invoke this skill when the user:

• Says "document this solution", "save this for next time"
• Says "create SOP", "make this reusable"
• Solves a novel issue and mentions "don't want to hit this again"
• Sets up integration and says "document the setup"
• Establishes pattern and mentions "team should follow this"

DO NOT invoke if:

• Creating task documentation (use nav-task skill)
• Updating architecture docs (different purpose)
• Simple bug fix with no reusable pattern

Execution Steps

Step 1: Determine SOP Category

Ask user which category (or infer from context):

Categories:

1. integrations - Third-party service setups
2. debugging - Common issues & solutions
3. development - Dev workflows, patterns
4. deployment - Deploy procedures, CI/CD

Examples:

• "How to set up Stripe webhooks" → integrations/
• "Fixing CORS errors" → debugging/
• "Testing authenticated routes" → development/
• "Deploy to production" → deployment/

Step 2: Determine SOP Name

If user provided name:

• Use their name (sanitize: lowercase, hyphens)
• Example: "Stripe Payment Setup" → "stripe-payment-setup"

If no name provided:

• Generate from context: {service}-{action}
• Example: "github-oauth-integration"
• Example: "cors-proxy-errors"

Step 3: Check if SOP Already Exists

Check existing SOPs in category:

ls .agent/sops/{category}/*.md 2>/dev/null

If similar SOP exists:

⚠️  Similar SOP found:
   .agent/sops/{category}/{similar-name}.md

Options:
1. Read existing SOP (don't duplicate)
2. Update existing SOP (add to it)
3. Create new SOP (different enough)

Step 4: Generate SOP Content

Create SOP document from conversation:

# {SOP Title}

**Category**: {integrations|debugging|development|deployment}
**Created**: {YYYY-MM-DD}
**Last Updated**: {YYYY-MM-DD}

[Explanation of what this accomplishes]

**Expected output**:

• [email protected]

added 1 package

### Step 2: {Next Action}

## Complete Example

### Full Working Code

**File**: `src/services/stripe.ts`

import Stripe from 'stripe';

export class StripeService { private stripe: Stripe;

constructor() { this.stripe = new Stripe(process.env.STRIPESECRETKEY!, { apiVersion: '2023-10-16', }); }

async createPaymentIntent(amount: number) { return await this.stripe.paymentIntents.create({ amount: amount * 100, // Convert to cents currency: 'usd', }); } }

**File**: `src/routes/webhook.ts`

export async function handleStripeWebhook(req: Request, res: Response) { const sig = req.headers['stripe-signature'];

try { const event = stripe.webhooks.constructEvent( req.body, sig, process.env.STRIPEWEBHOOKSECRET! );

// Handle event switch (event.type) { case 'payment_intent.succeeded': // Process successful payment break; }

res.json({ received: true }); } catch (err) { res.status(400).send(Webhook Error: ${err.message}); } }

---

## Testing

### Verify It Works

**Test 1: Create payment intent**

curl -X POST http://localhost:3000/api/create-payment \ -H "Content-Type: application/json" \ -d '{"amount": 10}'

**Expected result**:

{ "clientSecret": "pixxxsecret_yyy" }

**Test 2: Webhook delivery**

stripe listen --forward-to localhost:3000/webhook

**Expected result**:

Ready! You are using Stripe API Version [2023-10-16]

## Prevention

**How to avoid this issue in future**:
- [Prevention strategy 1]
- [Prevention strategy 2]

**Red flags to watch for**:
- [Warning sign 1]
- [Warning sign 2]

---

## Troubleshooting

### Issue: Webhook signature verification fails

**Symptoms**:

Error: No signatures found matching the expected signature

**Cause**: Webhook secret mismatch or body already parsed

**Fix**:

// Use raw body for webhook verification app.post('/webhook', express.raw({type: 'application/json'}), handleStripeWebhook);

### Issue: Payment amount incorrect

**Symptoms**: Charged wrong amount

**Cause**: Forgot to convert to cents

**Fix**: Always multiply by 100 for Stripe amounts

Step 5: Save SOP File

Write to appropriate category:

Write(
  file_path: ".agent/sops/{category}/{name}.md",
  content: [generated SOP]
)

Filename: .agent/sops/{category}/{name}.md

Step 6: Update Navigator Index

Edit .agent/DEVELOPMENT-README.md to add SOP to index:

## Standard Operating Procedures

### Integrations
- **{Service}**: `.agent/sops/integrations/{name}.md` - {One-line description}

### Debugging
- **{Issue}**: `.agent/sops/debugging/{name}.md` - {Description}

### Development
...

### Deployment
...

Step 7: Link to Related Task (If Applicable)

If SOP came from specific task, add reference:

In task doc:

## Related SOPs

- `.agent/sops/integrations/stripe-payment-setup.md`

In SOP:

## Related Documentation

- Task: `.agent/tasks/TASK-04-stripe-integration.md`

Cross-linking helps discoverability.

Step 8: Confirm Success

Common Use Cases

After Solving Tricky Bug

User: "Finally fixed CORS issue, save this so we don't hit it again"
→ Creates: .agent/sops/debugging/cors-proxy-errors.md
→ Captures: Error, root cause, fix, prevention
→ Team won't repeat mistake

After Integration Setup

User: "Stripe webhooks working, document the setup"
→ Creates: .agent/sops/integrations/stripe-webhooks.md
→ Captures: All config steps, code, testing
→ Next integration is copy-paste

Establishing Team Pattern

User: "Document how we test protected routes"
→ Creates: .agent/sops/development/testing-auth-routes.md
→ Captures: Pattern, examples, best practices
→ Team follows consistent approach

Error Handling

Category directory doesn't exist:

Creating category: .agent/sops/{category}/
✅ Directory created

SOPs directory missing entirely:

❌ Navigator not initialized

Run /nav:init to create .agent/ structure.

Duplicate SOP name:

⚠️  SOP already exists: {name}.md

Options:
1. Read existing (don't duplicate)
2. Update existing (add new info)
3. Rename new SOP ({name}-v2.md)

Success Criteria

SOP creation is successful when:

• SOP file created in correct category
• Contains all required sections
• Includes working code examples
• Testing instructions provided
• Navigator index updated
• Linked to related task (if applicable)

Scripts

generate_sop.py: Create SOP from conversation

• Input: Conversation, category, name
• Output: Formatted SOP markdown

Best Practices

Good SOP names:

• stripe-payment-integration (specific, descriptive)
• cors-proxy-configuration (clear purpose)
• jwt-token-refresh (explains what)

Bad SOP names:

• fix (too vague)
• integration (not specific)
• sop1 (meaningless)

When to create SOPs:

• ✅ Solved novel issue (will happen again)
• ✅ Set up integration (reusable process)
• ✅ Established pattern (team should follow)
• ✅ Complex workflow (needs documentation)
• ❌ One-off bug (not reusable)
• ❌ Obvious solution (don't over-document)

SOP quality checklist:

• Clear problem description
• Step-by-step solution
• Complete code examples (copy-paste ready)
• Testing instructions
• Troubleshooting common issues

Notes

SOPs are living documents:

• Created when pattern established
• Updated when solution improves
• Referenced frequently by team
• Prevent repeated mistakes

They transform:

• Individual knowledge → Team knowledge
• One-time solution → Reusable process
• Tribal knowledge → Documented procedure

Impact: Zero repeated mistakes over time

This skill provides same functionality as /nav:doc sop command but with natural language invocation.
