Traces how errors and exceptions flow through critical code paths to find swallowed errors and broken propagation. Use when analyzing exception handling on important paths.
We split this skill into the rules it gives an agent
4 rules. About 0 are common, 4 are distinctive, and 0 are very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈4
Distinctive · estimate
This author's own choices. Worth a look.
0
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Distinctive: line 14
If no target path is given above, review the entire codebase.
- Distinctive: line 61
Prefer minimal, drop-in fix snippets over prose.
- Distinctive: line 63
Do not invent files or functions that aren’t present.

Write this into a markdown file and place it in the audits/ folder.
≈ “Common” is an estimate: at least 1 in 5 of the 308,232 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.
Files
Target: $ARGUMENTS
If no target path is given above, review the entire codebase.
Trace error flow through the application:
Critical paths to analyze:
- Database connection failure
- Third-party API timeout
- Invalid user input
- Authentication failure
- File system errors
For each path, verify:
- Where is the error caught?
- How is it transformed?
- What gets logged?
- What does the user see?
- Is the system state consistent?
In the audit report, document the error flow as a text diagram or structured list showing:
- Error origin points
- Transformation layers
- Final handling points
- Recovery mechanisms
Anti-patterns to identify:
- Swallowed exceptions (empty catch blocks)
- Generic catch-all handlers hiding specific errors
- Errors used for flow control
- Missing error boundaries
- Inconsistent error formats
Provide a standardized error handling template.
Provide:
A structured finding report
A scale of 1/10 on how important each finding is
Remediation: precise code-level fix or config change (snippets welcome) if possible
Constraints & style:
Be concrete and cite exact code locations and identifiers.
Prefer minimal, drop-in fix snippets over prose.
Do not invent files or functions that aren’t present; if context is missing, mark as Unable to verify and say what code would prove it.

Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.
No reviews yet
People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.
- It worked
- Partly
- It didn't
Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
