What it does

Error Handling Gate is an agent skill from DanielPodolsky/ownyourcode. Verifies error handling including empty catch detection, user-friendly messages, and logging. WARNING gate triggered during /own:done flow.

Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Error handling. The repository describes itself as: Claude Code workflow for AI-mentored development. Work efficiently with Spec-Driven Development and the 6 Gates. Built to fight cognitive offloading — for developers using AI to… The licence is MIT.

When your agent uses it

Tasks that involve Error handling

Example prompts

“Use the error-handling-gate skill to verify error handling including empty catch detection, user-friendly messages, and logging”
“/error-handling-gate”

Workflow steps

4 steps, taken from the step headings in SKILL.md.

Empty Catch Blocks
Missing Finally for Cleanup
Technical Errors Exposed
No Error Differentiation

What it can do on your machine

Read from SKILL.md and the folder at commit bd1f17c. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
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

Error Handling Gate loads about 1.4k tokens when it runs. Until then it costs about 40 tokens; SKILL.md has 462 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~40
When it runs · the whole SKILL.md, loaded when a task matches: ~1.4k

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 passed

The automated check found no risky patterns in SKILL.md.

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.

Gate 3: Error Handling Review

"Happy path code is easy. Error handling is where senior engineers shine."

Purpose

This gate ensures the code handles failures gracefully, provides meaningful feedback to users, and doesn't silently swallow errors.

Gate Status

PASS — Error handling is appropriate
WARNING — Issues found that should be addressed

Gate Questions

Question 1: Failure Scenario

"What happens if [main operation] fails? Walk me through the user experience."

Looking for:

Awareness of failure modes
User-friendly error messages
Recovery options (retry, fallback)
No silent failures

Example scenarios:

Network request fails
Database is down
Validation fails
Third-party API errors

Question 2: User Feedback

"What does the user see when an error occurs? Would they understand what to do next?"

Looking for:

Helpful, non-technical messages
Actionable guidance ("Try again", "Check your connection")
Appropriate error placement in UI

Question 3: Error Visibility

"How would you debug this in production if something went wrong?"

Looking for:

Errors are logged
Sufficient context in logs
No sensitive data in logs
Error tracking awareness (Sentry, etc.)

Error Handling Checklist

Async Operations

All async calls wrapped in try/catch or .catch()
No empty catch blocks
Errors include context (what operation, what data)
finally blocks for cleanup (loading states, etc.)

User Experience

User-friendly error messages (no technical jargon)
Errors are actionable (what can user do?)
Loading states cleared on error
Retry options where appropriate

Logging & Debugging

Errors logged with context
No sensitive data in error logs
Error types/codes for categorization
Stack traces available in development

Edge Cases

Empty states handled
Timeout handling
Partial failure handling (some items succeed, some fail)
Concurrent request handling

Response Templates

If PASS

✅ ERROR HANDLING GATE: PASSED

Error handling looks solid:
- Async operations properly wrapped
- User-friendly error messages
- Errors logged for debugging

Moving to the next gate...

If WARNING

⚠️ ERROR HANDLING GATE: WARNING

Found [X] error handling concerns:

**Issue 1: [Empty catch block / Missing error handling]**
Location: `file.ts:42`
Question: "What happens when this fails silently?"

**Issue 2: [Technical error shown to user]**
Location: `file.ts:88`
Question: "Will users understand 'TypeError: Cannot read property...'?"

**Issue 3: [No loading state cleanup]**
Location: `file.ts:100`
Question: "What happens to the loading spinner if this fails?"

These should be addressed to ensure a good user experience.

Common Issues to Check

1. Empty Catch Blocks

❌ try {
     await submitForm();
   } catch (error) {
     // Silent failure - user has no idea
   }

✅ try {
     await submitForm();
   } catch (error) {
     console.error('Form submission failed:', error);
     setError('Could not submit. Please try again.');
   }

2. Missing Finally for Cleanup

❌ try {
     setLoading(true);
     await fetchData();
     setLoading(false);
   } catch (error) {
     handleError(error);
     // Loading stays true forever!
   }

✅ try {
     setLoading(true);
     await fetchData();
   } catch (error) {
     handleError(error);
   } finally {
     setLoading(false);
   }

3. Technical Errors Exposed

❌ catch (error) {
     setError(error.message);
     // User sees: "TypeError: Cannot read property 'map' of undefined"
   }

✅ catch (error) {
     console.error('Load failed:', error);
     setError('Something went wrong. Please try again.');
   }

4. No Error Differentiation

❌ catch (error) {
     setError('Error');
   }

✅ catch (error) {
     if (error.status === 401) {
       setError('Please log in to continue.');
       redirectToLogin();
     } else if (error.status === 404) {
       setError('Item not found.');
     } else if (error.name === 'NetworkError') {
       setError('Check your internet connection.');
     } else {
       setError('Something went wrong. Please try again.');
     }
   }

Socratic Error Questions

Instead of pointing out the fix, ask:

"What happens if the network is down when the user clicks this?"
"If this catch block runs, what will the user see?"
"How will you know this failed in production?"
"What if only some of the items fail to save?"
"Is the loading spinner stuck if an error happens?"

Error Message Quality Check

Bad Message	Better Message
"Error"	"Could not save. Please try again."
"An error occurred"	"Unable to load your profile. Check your connection."
"TypeError: undefined"	"Something went wrong. Please refresh and try again."
"500 Internal Server Error"	"Our servers are having trouble. Please try again in a moment."
"Failed"	"Could not complete your request. Need help? Contact support."

Severity Guide

Issue	Severity	Impact
Empty catch block	HIGH	Silent failures, hard to debug
No loading state cleanup	MEDIUM	Stuck UI, poor UX
Technical error shown	MEDIUM	Confusing UX, potential info leak
No retry option	LOW	Minor UX friction
Generic error message	LOW	Less helpful but not broken
