Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00055 | $0.02166 |
| Opus 5 | $0.00028 | $0.01083 |
| Sonnet 5 | $0.00011 | $0.00433 |
| Haiku 4.5 | $0.00006 | $0.00217 |
Grade A, and why
error-tracking scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Sentry Integration Skill
Purpose
This skill enforces comprehensive Sentry error tracking and performance monitoring across all services following Sentry v8 patterns.
When to Use This Skill
- Adding error handling to any code
- Creating new controllers or routes
- Instrumenting cron jobs
- Tracking database performance
- Adding performance spans
- Handling workflow errors
🚨 CRITICAL RULE
ALL ERRORS MUST BE CAPTURED TO SENTRY - No exceptions. Never use console.error alone.
Current Status
Example: API Service ✅ Complete
- Sentry v8 fully integrated
- All workflow errors tracked
- Background job processors instrumented
- Test endpoints available
Sentry Integration Patterns
1. Controller Error Handling
// ✅ CORRECT - Use BaseController
import { BaseController } from '../controllers/BaseController';
export class MyController extends BaseController {
async myMethod() {
try {
// ... your code
} catch (error) {
this.handleError(error, 'myMethod'); // Automatically sends to Sentry
}
}
}
2. Route Error Handling (Without BaseController)
import * as Sentry from '@sentry/node';
router.get('/route', async (req, res) => {
try {
// ... your code
} catch (error) {
Sentry.captureException(error, {
tags: { route: '/route', method: 'GET' },
extra: { userId: req.user?.id }
});
res.status(500).json({ error: 'Internal server error' });
}
});
3. Workflow Error Handling
Example of a domain-specific Sentry helper from the original production project. If you build a helper like this for your domain, the call site looks like:
import { WorkflowSentryHelper } from '../workflow/utils/sentryHelper';
WorkflowSentryHelper.captureWorkflowError(error, {
workflowCode: 'INVOICE_APPROVAL',
instanceId: 123,
stepId: 456,
userId: 'user-123',
operation: 'stepCompletion',
metadata: { additionalInfo: 'value' }
});
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

error-tracking is a skill published in the GitHub repository diet103/claude-code-infrastructure-showcase (10,016 stars, last pushed 1mo ago), licensed MIT. It adds 55 tokens to every session and 2,166 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
