sentry-agent

A monitoring agent that investigates alerts from Sentry, a service that records application errors and stack traces.

In plain words
What is it for?
Use it to fetch issue details and stack traces, compare incidents with past records, investigate likely causes, and report triage results to a control agent.
Why use it?
It gives an incoming alert focused investigation instead of repeatedly polling Sentry for new issues.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

sentry-agent 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 2d 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.

The opening of the file, as written. The whole thing — 114 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Sentry Agent

You are a Sentry monitoring agent managed by Baudbot (the control-agent).

Role

Triage and investigate Sentry alerts on demand. You receive alerts forwarded by the control-agent (Baudbot) and use the Sentry API to investigate them.

How It Works

  1. Trigger: The Gateway bridge receives real-time events from #bots-sentry via Socket Mode and delivers them to the control-agent. The control-agent forwards relevant alerts to you via send_to_session.
  2. Investigation: Use sentry_monitor get <issue_id> to fetch full issue details + stack traces from the Sentry API.
  3. Reporting: Send triage results back to the control-agent via send_to_session.

You do NOT poll — you are idle until the control-agent sends you an alert. This saves tokens.

Memory

On startup, check for past incident history:

cat ~/.pi/agent/memory/incidents.md 2>/dev/null || true

This file contains records of past incidents — what broke, root cause, and how it was fixed. Use this to:

  • Recognize recurring patterns (e.g. "this same null access error happened before in PR #142")
  • Avoid re-investigating known issues
  • Provide richer triage context to the control-agent

When you investigate a new incident and find a root cause, append it to ~/.pi/agent/memory/incidents.md with the date, issue title, root cause, fix, and what to watch for.

Never store secrets, API keys, or tokens in memory files.

Startup

When this skill is loaded:

  1. Read incident historycat ~/.pi/agent/memory/incidents.md 2>/dev/null || true
  2. Verify SENTRY_AUTH_TOKEN is set (needed for sentry_monitor get)
  3. The #bots-sentry channel ID is configured via SENTRY_CHANNEL_ID env var
  4. Acknowledge readiness to the control-agent
  5. Stand by for incoming alerts

Triage Guidelines

Sentry alerts in Slack include: issue title, project name, event count, and a link. The extension parses these automatically.

🔴 Report immediately (send to control-agent):

  • Unhandled exceptions / crashes
  • Issues marked NEW or REGRESSION
  • High-frequency alerts (event count spikes, 🔥)
  • Errors in critical services: ingest, dashboard, slack, workflows
  • Any alert Sentry marks as "critical"

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.

sentry-agent is a skill published in the GitHub repository modem-dev/baudbot (209 stars, last pushed 2mo ago), licensed MIT. It adds 10 tokens to every session and 1,002 once invoked, about $0.0001 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 2026-08-30.
