Error

Error handling reference — error types, exception patterns, HTTP status codes, retry strategies, and observability. Use when designing error handling, debugg...

Security Scan

The skill is an offline error-handling reference that runs a bundled shell script to print documentation; its requirements and behavior match its description and nothing obvious or disproportionate is requested.

Purpose & Capability

The name/description (error-handling reference) matches the provided assets: an instruction-only skill that calls a bundled scripts/script.sh which prints documentation for error handling, HTTP status codes, retry strategies, logging, etc. There are no unexpected credentials, binaries, or external services required.

Instruction Scope

SKILL.md directs the agent to run local commands like `scripts/script.sh intro` and other subcommands. The included script appears to only output reference text (cat << 'EOF' blocks) for each command. The instructions do not ask the agent to read unrelated system files, access external endpoints, or collect user secrets.

Install Mechanism

No install spec is provided and the skill is instruction-only with a local script. Nothing is downloaded or extracted from remote URLs, so there is no elevated install risk.

Credentials

The skill declares no required environment variables or credentials. SKILL.md documents an optional ERROR_DIR (default ~/.error/) for data, which is reasonable for a doc/reference skill; no sensitive secrets are requested.

Persistence & Privilege

always is false and the skill does not request permanent system presence. The skill will only run when invoked and does not modify other skills or global agent configuration.

Assessment

This skill appears to be a local documentation tool implemented as a bundled shell script that prints error-handling guidance. It is coherent with its description and doesn’t request credentials or network access. Before installing or running: (1) quickly review scripts/script.sh yourself to confirm it only prints text (search for network commands like curl, wget, nc, ssh or file-write operations), (2) avoid running it as an elevated user (root) if you have concerns, and (3) if you expect persistent data, check how ERROR_DIR is used and whether files are written there. If you want extra assurance, run the script in an isolated environment (container) and inspect its output and any files it creates.

Error — Error Handling & Resilience Reference

Quick-reference skill for error handling patterns, HTTP status codes, retry strategies, and debugging techniques.

When to Use

• Designing error handling strategy for an application
• Looking up HTTP status codes and their proper usage
• Implementing retry logic with backoff strategies
• Debugging production errors and failure patterns
• Building resilient systems with circuit breakers
