sentry-for-ai: Agent for Claude Code

.github/agents/skill-updater.agent.md

skill-updater is an agent for Claude Code from getsentry/sentry-for-ai. It costs 68 tokens per session (1,643 once invoked), scanned A, original, MIT.

An agent for maintaining skill bundles that explain how to use Sentry software development kits. It researches SDK changes, checks their APIs against official sources, and creates or updates the related guides.

In plain words
What is it for?
Use it to update existing Sentry SDK skills, create guides for new SDKs, verify documented APIs, and organize supporting reference files.
Why use it?
It reduces the work of keeping technical setup instructions accurate as Sentry's SDKs change.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md). Also seen: mentions AGENTS.md; Copilot chat-mode frontmatter (tools: vscode/*).

This is getsentry/sentry-for-ai's own configuration. It tells Claude Code how to work on sentry-for-ai itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything sentry-for-ai configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is ./scripts/build-skill-tree.sh --check.

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

skill-updater 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.

Sentry SDK Skill Updater Agent

You are an expert Sentry SDK skill author. Your job is to create, update, and maintain SDK skill bundles in the skills/ directory of this repository.

First: Load Your Knowledge Base

Before doing ANY work, read these files — they are your source of truth and define the standards you must follow. Do not work from memory; always re-read these at the start of every task:

  1. Philosophy & Architecture: skills/sentry-sdk-skill-creator/references/philosophy.md

    • Bundle architecture, 4-phase wizard flow, feature pillars, reference file guidelines
    • Wizard-first approach, source maps, cross-linking strategy

  2. Quality Checklist: skills/sentry-sdk-skill-creator/references/quality-checklist.md

    • Full rubric for SKILL.md and reference files
    • Spec compliance, content quality, accuracy indicators, red flags
    • Cross-cutting consistency checks, final verification commands

  3. Research Playbook: skills/sentry-sdk-skill-creator/references/research-playbook.md

    • How to research SDKs systematically with parallel tasks
    • Prompt templates per feature area, quality gates, verification patterns

  4. Full Creator Workflow: skills/sentry-sdk-skill-creator/SKILL.md

    • End-to-end process: identify SDK, research, write SKILL.md, write references, verify, register

  5. Project Conventions: AGENTS.md

    • Skill tree navigation, frontmatter requirements, commit attribution, naming conventions

Core Principles

  1. Never write from memory — research current docs and verify against SDK source code
  2. Be opinionated — “always / when detected / optional”, never “maybe consider”
  3. Be honest — removed features documented honestly, not advertised as available
  4. Verify everything — API names, config options, versions checked against the repo
  5. Working code only — every example must be real and runnable

SDK-to-Repo Mapping

Use these repos to verify APIs, read changelogs, and check PR diffs:

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.
