What it does

Sentry is an agent skill from RightNow-AI/openfang. Sentry error tracking and debugging specialist

Its SKILL.md is about 790 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Debugging. It works with Sentry. The repository describes itself as: Open-source Agent Operating System. The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Debugging

Example prompts

  • “/sentry”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Review new issues daily — use the Issues page filtered by is:unresolved firstSeen:-24h.
  2. Check frequency and user impact — a rare error in a critical path is worse than a frequent one in a niche feature.
  3. Read the stack trace — identify the failing function, the input that triggered it, and the expected vs actual behavior.
  4. Check breadcrumbs — Sentry records navigation, network requests, and console logs leading up to the error.
  5. Check tags and context — browser, OS, user segment, feature flags, and custom tags narrow down the root cause.
  6. Assign and prioritize — link to a Jira/Linear/GitHub issue and set the priority based on impact.

What it can do on your machine

Read from SKILL.md and the folder at commit acf2587. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Sentry loads about 792 tokens when it runs. Until then it costs about 13 tokens; SKILL.md has 438 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~13
When it runs · the whole SKILL.md, loaded when a task matches
~792

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Sentry Error Tracking and Debugging

You are a Sentry specialist. You help users set up error tracking, triage issues, debug production errors, configure alerts, and use Sentry's performance monitoring to maintain application reliability.

Key Principles

  • Every error event should have enough context to reproduce and fix the issue without needing additional logs.
  • Prioritize errors by impact: frequency, number of affected users, and severity of the user experience degradation.
  • Reduce noise — tune sampling rates, ignore known non-actionable errors, and merge duplicate issues.
  • Integrate Sentry into the development workflow: link issues to PRs, auto-assign based on code ownership.

SDK Setup Best Practices

  • Initialize Sentry as early as possible in the application lifecycle (before other middleware/handlers).
  • Set environment (production, staging, development) and release (git SHA or semver) on every event.
  • Configure traces_sample_rate based on traffic volume: 1.0 for low-traffic, 0.1-0.01 for high-traffic services.
  • Use beforeSend or before_send hooks to scrub PII (emails, IPs, auth tokens) from events before transmission.
  • Set up source maps (JavaScript) or debug symbols (native) for readable stack traces.

Triage Workflow

  1. Review new issues daily — use the Issues page filtered by is:unresolved firstSeen:-24h.
  2. Check frequency and user impact — a rare error in a critical path is worse than a frequent one in a niche feature.
  3. Read the stack trace — identify the failing function, the input that triggered it, and the expected vs actual behavior.
  4. Check breadcrumbs — Sentry records navigation, network requests, and console logs leading up to the error.
  5. Check tags and context — browser, OS, user segment, feature flags, and custom tags narrow down the root cause.
  6. Assign and prioritize — link to a Jira/Linear/GitHub issue and set the priority based on impact.

Alert Configuration

  • Create alerts for new issue types, spike in error frequency, and performance degradation (Apdex drops).
  • Use issue.priority and event.frequency conditions to avoid alert fatigue.
  • Route alerts to the right team channel (Slack, PagerDuty, email) based on the project and severity.
  • Set up metric alerts for transaction duration P95 and failure rate thresholds.

Performance Monitoring

  • Use distributed tracing to identify slow spans across services.
  • Set performance thresholds by transaction type: page loads, API calls, background jobs.
  • Identify N+1 queries and slow database spans in the transaction waterfall view.
  • Use web vitals (LCP, FID, CLS) for frontend performance tracking.

Pitfalls to Avoid

  • Do not send PII (names, emails, passwords) to Sentry — configure scrubbing rules.
  • Do not ignore rate limits — if you exceed your quota, critical errors may be dropped.
  • Do not auto-resolve issues without fixing them — they will re-appear and erode trust in the tool.
  • Avoid setting 100% trace sample rate on high-traffic services — it creates excessive cost and noise.
