Automated safety checks
This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.
Declares what it does: passed
SKILL.md parses and declares a name and a description.
SKILL.md exists, its frontmatter parses, and it declares a name and a description.
No undeclared network calls: passed
Makes no network calls.
Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.
No obfuscated payloads: passed
No encoded or obfuscated payloads.
No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.
No credential access: passed
Reads no keys, tokens, keychains or credential files.
Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.
No pipe-to-shell installers: passed
No pipe-to-shell or download-and-run installers.
No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

About this skill
What it does
This skill equips AI agents to write robust Go code by automatically generating idiomatic error handling patterns, such as wrapping errors with context and implementing retry logic. It ensures that failure scenarios are managed gracefully rather than causing silent crashes or unhandled panics in backend services.
When to use it
- You need to refactor legacy Go functions that lack proper
errors.Unwrap()chains for better debugging. - Your agent is generating database query code where network timeouts require specific retry mechanisms.
- You want the agent to create API handlers that return structured error responses instead of raw panic messages.
- You are building a microservice and need consistent logging of error contexts across different modules.
Key capabilities
- Generates context-aware error wrapping using standard Go libraries.
- Implements exponential backoff strategies for transient failures.
- Creates custom error types with descriptive messages and stack traces.
- Ensures all
deferstatements correctly close resources on error paths.
Example prompts
"Write a Go function that fetches user data from an API, wrapping any network errors with the request ID."
"Create a retry loop for a database transaction that implements exponential backoff if a deadlock occurs."
"Refactor this handler to return a custom ValidationError type instead of panicking when input is missing."
Tips & gotchas
Ensure your Go version is 1.20 or higher, as the skill relies on modern error handling idioms like errors.Is() and errors.As(). Avoid using this skill for simple scripts where verbose error wrapping might clutter the output unnecessarily.
