Nobody at Sentry asked for this audit or this post.
On 30 September I published an audit of the agent instruction files in getsentry/sentry: the root AGENTS.md, the area files under src/, static/ and tests/, and the .claude/ commands and settings. That is 15 files, pinned to commit 0f24ade. There were twelve findings, each with a file and a line. Before publishing, I sent every finding cold to a second, unrelated model and told it to disprove each one. It refuted one and narrowed ten, so the page went up with eleven.
On 16 October Sentry merged a refresh of its backend agent docs, written by its own agent, which "checked each claim in AGENTS.md, src/AGENTS.md, tests/AGENTS.md, and the backend subsystem docs against the current code." It did not see my audit, and it left the frontend docs out of scope. For the backend files, it is still the nearest thing to an answer key I will get, so I scored the audit against it.
Fixed, and I had flagged it: 3
- src/AGENTS.md told agents to register integrations in src/sentry/integrations/registry.py. That file does not exist. Their fix names the real mechanism, SENTRY_DEFAULT_INTEGRATIONS.
- Three paths that had moved (models/outbox.py, routes.tsx, the test factories). Fixed across two PRs.
- RegionSiloEndpoint. I called it a low-severity naming ambiguity. The symbol did not exist at all, so I graded it too softly.
Still there: 7
static/AGENTS.md still says images live in static/app/images and load through a "webpack loader". The alias in rsbuild.config.ts points at static/images, and the build is Rsbuild. The refresh left frontend docs out of scope, so this says nothing about whether they agree.
The other six are about structure and upkeep. A directory's rules are reached by no pointer file. Permissions in .claude/settings.json do not match the commands the docs give. One editor's parameter is written as a rule for every agent. Nothing marks which rules a lint enforces. A deprecated hook has no tracking issue. And an "always update this file" rule names no reviewer. A refresh that checks claims against code would not be expected to touch these, so they got no ruling either way. Two of them are weaker than I wrote; see below.
Fixed, and I had missed it: 5
1. The pre-commit command used the hook id ruff. The real ids are ruff-check and ruff-format; the command fails with "No hooks found".
2. The task guide described Celery options (queue, max_retries). Tasks run on taskbroker now.
3. The guide put organization management in the control silo. Organization is a cell-silo model.
4. "Inherit from Integration." That name is a database model, not the base class. This was on the same line as my first finding. I read the line, caught the path, and missed the second wrong fact in it.
5. An anti-pattern ("no direct model import in API") that, by their count, about 135 of 158 endpoint files break.
All five were checkable at my pinned commit. Every one is a symbol or a meaning, not a path. My sample said it checked paths and did not check symbols, which is true, and also exactly where the misses were.
Where I was wrong
- I said setup-dev is a command and not a skill. .agents/skills/setup-dev/ exists at the pin.
- I said no owner is named for the agent files. .github/CODEOWNERS line 131 assigns /AGENTS.md to a team. I never opened CODEOWNERS, and two of the seven open findings lean on that claim.
What changes in how I audit
Path checks are cheap. Claude Code 2.1.283 has /doctor prompt-audit, which checks CLAUDE.md, AGENTS.md and .claude/ for files and commands that do not exist. Run it.
Every miss here was a sentence that names something real and says something false about it. Sentry's agent found them by checking each sentence against the code.

Error tracking that reads your code Sentry lets you detect, trace, and fix issues in real time, so you spend less time hunting bugs. 🍒 Built by the Sentry team getsentry/sentry #opensource #python
又是「我这里没问题」？查线上 Bug，光靠一句描述可不够 🔍 Sentry 是一个面向开发者的错误追踪与性能监控平台，把应用报错和性能问题集中起来查看，为排查故障提供线索。它的重点不是替你保证代码永远不出错，而是让问题发生后，有更多信息可供追查。[GitHub](getsentry/sentry) 接入不一定要先部署整套后端：给自己的应用接上官方 SDK，完成对应项目的配置，就可以把相关事件发送到选定的 Sentry 服务。官方提供 JavaScript、Python、Java、Go 等多种 SDK，但具体支持哪些框架和运行环境，要按所选 SDK 的版本核对，不能理解成所有项目都能无条件兼容。[GitHub](getsentry/sentry) 可以选择官方托管，也可以自行部署。托管服务的 Developer 免费档有额度和功能限制，更高用量、付费功能需要按实际方案计算；自托管则要承担服务器、存储和日常维护成本，不是把代码下载下来就没有后续开销。[Sentry 文档](docs.sentry.io) 许可也值得单独看清：当前主项目采用 FSL-1.1-Apache-2.0，属于源码可用，而不是没有商业用途限制的开源软件。它限制将代码用于竞争性商业产品或服务；根据官方许可，每个版本公开发布满两年后，该版本会额外获得 Apache-2.0 授权，不能把这个期限理解成整个项目届时统一解除限制。[Sentry](open.sentry.io) 接入监控，也意味着需要认真检查数据流向。SDK 会向配置的服务端发送遥测数据，可能包含 URL、事件轨迹（breadcrumbs）、请求上下文，以及设备和运行环境信息；上传 Source Map，还可能让服务端获得对应的源码上下文。上线前应按具体 SDK、版本和启用功能，核对采集范围与脱敏设置。[Sentry 文档](docs.sentry.io) 默认脱敏不是「绝不会带上个人信息」的保证，服务端脱敏也不等于敏感内容从未被传输。需要阻止数据外发，就应在 SDK 发送前做好过滤；即使自行部署，也仍要检查外部集成和网络请求，不能直接等同于完全离线。[Sentry 文档](docs.sentry.io) 🔗 getsentry/sentry
