What it does
Handling Errors is an agent skill from rileyhilliard/claude-essentials. Prevents silent failures and context loss in error handling. Use when writing try-catch blocks, designing error propagation, reviewing catch blocks, or implementing Result patterns.
Its SKILL.md is about 630 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/go.md`, `references/python.md` and `references/typescript-react.md`).
It works with React, Python and TypeScript. The licence is MIT.
When your agent uses it
- Writing try-catch blocks
- Designing error propagation
- Reviewing catch blocks
- Implementing Result patterns
Example prompts
- “Use the handling-errors skill to prevent silent failures and context loss in error handling”
- “/handling-errors”
What it can do on your machine
Read from SKILL.md and the folder at commit 3a67a01. 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 (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
Handling Errors loads about 632 tokens when it runs, and up to ~4.5k if it reads all its reference files. Until then it costs about 49 tokens; SKILL.md has 177 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 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.

Handling Errors
Error Categories
| Type | Examples | Handling |
|---|---|---|
| Expected | Validation, Not found, Unauthorized | Return Result type, log info |
| Transient | Network timeout, Rate limit | Retry with backoff, log warn |
| Unexpected | Null reference, DB crash | Log error, show support ID |
| Critical | Auth down, Payment gateway offline | Circuit breaker, alert |
Fail Fast vs Degrade Gracefully
Fail fast for critical dependencies:
await connectToDatabase(); // Throws on failure - app can't run without itDegrade gracefully for optional features:
const prefs = await loadPreferences(userId).catch(() => DEFAULT_PREFS);Log at the Right Layer
// ❌ Logging at every layer = same error 3x
async function fetchData() {
try { return await fetch(url); }
catch (e) { console.error("Fetch failed:", e); throw e; }
}
// ✅ Log once where handled
async function fetchData() {
const response = await fetch(url);
if (!response.ok) throw new Error(`HTTP ${response.status}`);
return response;
}
// Top level logs the error onceLanguage-Specific Patterns
- TypeScript/React: See references/typescript-react.md for Error Boundaries, typed errors, Result pattern, UI display
- Python: See references/python.md for EAFP, exception chaining, context managers
- Go: See references/go.md for explicit error returns, wrapping with %w, sentinel errors
Anti-Patterns
| Pattern | Problem | Fix |
|---|---|---|
| Empty catch blocks | Hides errors | Log or re-throw |
return false on error | Loses context | Return Result type |
| Generic "Error" messages | Undebuggable | Include what/why/context |
| Logging same error at each layer | Log pollution | Log once at boundary |
Bare except: / catch (e) all | Catches system signals | Catch specific types |
