handling-errors

handling-errors is a skill for Claude Code from ihistand/claude-plugins. It costs 150 tokens per session (2,073 once invoked), scanned A, original, no licence file.

An error-handling workflow for repositories that keep product requirements in a docs/prd folder. It covers reported bugs, incorrect output, failing or unreliable tests, failed deployments, stopped builds, and open error records.

In plain words
What is it for?
It is for diagnosing and resolving repository errors, test failures, build failures, deployment failures, and entries recorded in errors.md.
Why use it?
It gives these problems a documented path instead of treating each one as an isolated fix or retry.

Skill for Claude Code

Written for Claude Code: shipped in a Claude Code plugin.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

handling-errors scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
