getsentry/skills is a collection of agent skills that Sentry employees use to guide coding and development tasks according to the company's practices. It supports work such as code review, writing, commits, and repository configuration, rather than setting up Sentry or debugging production issues. The catalogue entries are the project's skills, instructions, setting, agent, and plugin.

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 | $0.00479 | $0.00479 |
| Opus 5.5 | $0.00192 | $0.00192 |
| Sonnet 5.5 | $0.00096 | $0.00096 |
| Haiku 4.5 | $0.00048 | $0.00048 |
Grade A, and why
skills 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 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.
What it actually says
Agent Instructions
Skill Structure
skills/<skill-name>/SKILL.md
skills/<skill-name>/SPEC.md
If you use Claude marketplace sparse checkouts for this repo, include skills and agents alongside .claude-plugin because the root plugin manifest loads repo-root skills/ and agents/.
Creating/Updating Skills
ALWAYS use /skill-writer — it handles requirements, writing, registration, and validation.
- Do not create per-skill alias or symlink skills
- The repo-level
.agents/skillspath is a convenience mirror of canonicalskills/ - List only canonical skills in public skill inventories (for example
pr-writer,skill-writer)
Registration Checklist
- Create
skills/<skill-name>/SKILL.md - Create
skills/<skill-name>/SPEC.md - Add to
README.mdAvailable Skills table (alphabetical by canonical skill name; exclude aliases/symlinks) - Add to
.claude/settings.json:Skill(sentry-skills:<skill-name>) - Add to allowlist in
skills/claude-settings-audit/SKILL.md - For skills with deliberate invocation policy, set Claude's
disable-model-invocationinSKILL.mdand Codex'spolicy.allow_implicit_invocationinagents/openai.yamlto matching behavior
Key Conventions
- Frontmatter
---must be the first line of SKILL.md — no comments before it namefield must match the directory name exactlydescriptionincludes trigger keywords — this is how agents discover the skill- Attribution comments go after the closing
--- - Python scripts: always use
uv run <script>, neverpythonorpython3 - Keep SKILL.md under 500 lines; move reference material to
references/ - Keep runtime instructions in
SKILL.md; put intent, source/evidence model, evaluation, limitations, and maintenance rules inSPEC.md

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.
