What it does
Sentry Analysis is an agent skill from Sidiora-Labs/centra-llm-agents. Analyze and fix production errors from Sentry crash reports. Use when investigating AppHang, ANR, crashes, or production errors. Includes complete workflow from JSON analysis to bug fix implementation with evidence-based methodology. Triggers on sentry, crash, AppHang, ANR, error analysis, production error, bug analysis, crash report, freeze, hang, not responding, stacktrace, breadcrumbs, exception.
Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/rules/fix-sentry-errors.md`).
It sits in Development, covering Mobile testing and debugging and Debugging. It works with Sentry. The repository describes itself as: A stateful AI operating system for serious, long-horizon work.
When your agent uses it
- Investigating AppHang
- Production errors
- Production error
Example prompts
- “/sentry-analysis”
Requirements
- Pre-approved tools (allowed-tools): Read, Grep, Glob, Write, Edit, Bash
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- ✅ Always create a bug analysis log in node_modules/.cache/bugs/ before implementing fixes
- 🚨 MUST wait for user confirmation before starting any code changes
- ✅ Bug analysis must be complete with all sections filled
- ✅ Use evidence-based methodology (环环相扣，逐步递进)
What it can do on your machine
Read from SKILL.md and the folder at commit 01c6aef. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadGrepGlobWriteEditBash
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Sentry Analysis loads about 1k tokens when it runs, and up to ~9.7k if it reads all its reference files. Until then it costs about 105 tokens; SKILL.md has 293 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
allowed-tools: Read, Grep, Glob, Write, Edit, Bash
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 293 words (~1,031 tokens).
