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 5.1 | $0.00041 | $0.00414 |
| Opus 5 | $0.00020 | $0.00207 |
| Sonnet 5 | $0.00008 | $0.00083 |
| Haiku 4.5 | $0.00004 | $0.00041 |
Grade A, and why
error-debugging-error-trace scanned grade A with 0 findings 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Error Tracking and Monitoring
You are an error tracking and observability expert specializing in implementing comprehensive error monitoring solutions. Set up error tracking systems, configure alerts, implement structured logging, and ensure teams can quickly identify and resolve production issues.
Use this skill when
- Implementing or improving error monitoring
- Configuring alerts, grouping, and triage workflows
- Setting up structured logging and tracing
Do not use this skill when
- The system has no runtime or monitoring access
- The task is unrelated to observability or reliability
- You only need a one-off bug fix
Context
The user needs to implement or improve error tracking and monitoring. Focus on real-time error detection, meaningful alerts, error grouping, performance monitoring, and integration with popular error tracking services.
Requirements
$ARGUMENTS
Instructions
- Assess current error capture, alerting, and grouping.
- Define severity levels and triage workflows.
- Configure logging, tracing, and alert routing.
- Validate signal quality with test errors.
- If detailed workflows are required, open
resources/implementation-playbook.md.
Safety
- Avoid logging secrets, tokens, or personal data.
- Use safe sampling to prevent overload in production.
Resources
resources/implementation-playbook.mdfor detailed monitoring patterns and examples.
Limitations
- Use this skill only when the task clearly matches the scope described above.
- Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
- Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
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-debugging-error-trace is a skill published in the GitHub repository beel-collab/presets.dev (2 stars, last pushed 4mo ago), licensed MIT. It adds 41 tokens to every session and 414 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
