What it does
Error Handling is an agent skill from Sidiora-Labs/centra-llm-agents. Error handling patterns and best practices. Use when implementing try/catch blocks, handling async errors, showing error messages, or managing error states in UI. Triggers on error, try, catch, exception, throw, fail, failure, error handling, error boundary, useAsyncCall, toast, fallback, error state.
Its SKILL.md is about 960 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/error-handling.md`).
It sits in Development, covering Error handling. The repository describes itself as: A stateful AI operating system for serious, long-horizon work.
When your agent uses it
- Implementing try/catch blocks
- Handling async errors
- Showing error messages
- Managing error states in UI
Example prompts
- “/error-handling”
Requirements
- Pre-approved tools (allowed-tools): Read, Grep, Glob
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:
ReadGrepGlob
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
Error Handling loads about 955 tokens when it runs, and up to ~2.1k if it reads all its reference files. Until then it costs about 79 tokens; SKILL.md has 144 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.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 144 words (~955 tokens).
“Best practices for error handling in applications.”

What does Error Handling do?
Error handling patterns and best practices. An agent skill from Sidiora-Labs/centra-llm-agents. Error Handling is an agent skill from Sidiora-Labs/centra-llm-agents. Error handling patterns and best practices.
When should I use Error Handling?
Error Handling fits situations like: implementing try/catch blocks; handling async errors; showing error messages; managing error states in UI.
How do I install Error Handling in Claude Code?
Run `npx skills add Sidiora-Labs/centra-llm-agents --skill error-handling -a claude-code`. Or copy the skill folder (protocol/skills/error-handling in Sidiora-Labs/centra-llm-agents) into .claude/skills/error-handling in your project. Claude Code loads it when a task matches its description.
How do I install Error Handling in Codex?
Run `npx skills add Sidiora-Labs/centra-llm-agents --skill error-handling -a codex`. Or copy the skill folder (protocol/skills/error-handling in Sidiora-Labs/centra-llm-agents) into .agents/skills/error-handling in your project. Codex loads it when a task matches its description.
Can I use Error Handling in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add Sidiora-Labs/centra-llm-agents --skill error-handling -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/error-handling, .gemini/skills/error-handling, .github/skills/error-handling and .opencode/skills/error-handling in your project.
What does Error Handling need to run?
SKILL.md names no scripts, command-line tools or credentials: Error Handling is instructions for the agent only. Its frontmatter pre-approves these tools: Read, Grep, Glob.
Does Error Handling access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Error Handling safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Error Handling use?
Error Handling has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
How many tokens does Error Handling use?
About 955 tokens (SKILL.md is roughly 3.8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 1.2k tokens, read only when the agent opens those files.
