What is investigate-sentry-issue?

A procedure for investigating and classifying an error recorded in Sentry, a service that collects application errors and their diagnostic details. It gathers issue metadata, stack traces, breadcrumbs, tags, and context.

Use it with a Sentry issue ID or URL to inspect when the error occurred, how often it happened, affected environments, and the actions and code path leading to it.

It turns a reported error into enough technical context to decide whether and how it should be fixed.

About the project

Agent Swarm is a self-hosted operating system for coordinating AI agents as a company-wide workforce. A lead agent assigns work to workers running in isolated containers, while shared memory, tools, schedules, workflows, and review gates preserve and manage that work. The catalogue entries provide agents, commands, skills, hooks, and other extensions for operating the system.

Install

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.

Clone the repo

git clone --depth 1 https://github.com/desplega-ai/agent-swarm

Made for: Claude Code.

Or install agent-swarm, the plugin that ships this one along with the rest of its 31 skills, 11 commands, 5 agents, 6 hooks, 1 MCP server.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00010	$0.00596
Opus 5.5	$0.00004	$0.00238
Sonnet 5.5	$0.00002	$0.00119
Haiku 4.5	$0.00001	$0.00060

Security

Grade A, and why

investigate-sentry-issue 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 2mo 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.

Investigate Sentry Issue

Investigate a Sentry issue to understand the error, gather context, and prepare for fixing or triaging.

Prerequisites

SENTRY_AUTH_TOKEN and SENTRY_ORG must be set. Verify with sentry-cli info.

Arguments

sentry-issue-url-or-id: A Sentry issue URL or just the issue ID (e.g., 123456)

Workflow

1. Parse the Input

If given a URL (https://sentry.io/organizations/{org}/issues/{issue_id}/), extract the issue ID.

2. Get Issue Overview

sentry-cli issues list --id <issue-id>

3. Get Detailed Info via REST API

Use https://sentry.io/api/0/organizations/${SENTRY_ORG}/issues/<issue-id>/ for metadata (first/last seen, event count, user impact, status).

4. Get Full Stacktrace

Use the recommended event endpoint: .../issues/<issue-id>/events/recommended/

Key jq paths for the response:

.entries[] | select(.type == "exception") — exception with stacktrace
.entries[] | select(.type == "exception") | .data.values[].stacktrace.frames — stack frames
.entries[] | select(.type == "breadcrumbs") — actions leading to the error
.tags — environment, browser, OS info
.context — custom context data

5. Analyze and Report

Identify the failing file and line number
Understand the error type and message
Review breadcrumbs for the sequence of events
Check tags for environment-specific issues

6. Take Action (if appropriate)

sentry-cli issues resolve <issue-id>    # Resolve
sentry-cli issues mute <issue-id>       # Mute
sentry-cli issues unresolve <issue-id>  # Unresolve

Search Query Syntax

Use these filters with sentry-cli issues list --query:

Filter	Example	Description
`is:`	`is:unresolved`	Issue status
`lastSeen:`	`lastSeen:-2d`	Seen within time range
`message:`	`message:undefined`	Match error message
`issue.category:`	`issue.category:error`	Error category

Tips

Always get the recommended event first — it's curated for debugging
Check breadcrumbs to understand user actions before the error
If investigating from a Slack alert, the issue URL is in the alert message

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.
