What is sentry-for-ai AGENTS.md?

Repository instructions for the Sentry plugin for AI coding assistants such as Claude Code, Cursor, Codex, and Grok. They describe its source layout, build process, versioning, skill rules, and required commit attribution.

Use them when developing or building Sentry assistant integrations, adding skills or references, updating manifests, or preparing commits and releases.

They prevent agents from editing generated distribution files or using unsupported skill metadata, and ensure AI-authored commits identify their model.

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	$0.02249	$0.02249
Opus 5.5	$0.00900	$0.00900
Sonnet 5.5	$0.00450	$0.00450
Haiku 4.5	$0.00225	$0.00225

Security

Grade A, and why

sentry-for-ai AGENTS.md 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 1mo 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.

Agent Instructions

Project Overview

Sentry plugin for AI coding assistants (Claude Code, Cursor, Codex, and Grok). Provides MCP server integration and skills.

Commit Attribution

AI commits MUST include:

Co-Authored-By: (the agent model's name and attribution byline)

Repository Structure

All buildable source lives under src/ — this repo is not itself an installable plugin.

src/skills/              # Skill library (source of truth)
src/references/          # Shared reference content hydrated into skills at build time
src/plugins/<agent>/     # Per-agent build scripts + manifests
src/plugins/version.json # The one release version, stamped into every manifest
src/SKILL_TREE.md        # Generated skill index (see Skill Tree Navigation below)

Per-agent plugin metadata is generated by the src/plugins/<agent>/build.sh scripts and published to each agent’s distribution repository; it is not committed here.

Skill frontmatter is name, description, and license. Nothing else is required, and the retired router fields (category, parent, role, disable-model-invocation) are rejected — see Skill Tree Navigation below.

Skills

src/SKILL_TREE.md is the list, generated from the skills themselves. Read it rather than a copy: an inventory duplicated here goes stale the first time a skill is added, renamed, or dissolved, which is exactly what happened to the one that used to live in this section.

The shape to know: every skill is flat and task-shaped — one skill, one job a user would name, found through its own description. Platform coverage is not a skill per SDK; per-platform install and signal code comes from the Sentry docs, which the shared sdk-docs.md reference maps each platform to.

MCP Server

Sentry MCP server configured at https://mcp.sentry.dev/mcp. The source of truth is mcp.json: Cursor consumes it as-is at the plugin root, while the Codex and Grok builds emit it as .mcp.json (Codex’s validator requires the dotted name; Grok auto-discovers it). Claude declares the server inline in its plugin.json (mcpServers), so the Claude build ships no MCP file.

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.
