promptIO: Skill for Claude Code

.agents/skills/python-error-handling/SKILL.md

python-error-handling is a skill for Claude Code, Codex from yashshinde0080/promptIO. It costs 43 tokens per session (2,373 once invoked), scanned B, original, no licence file.

A guide to handling errors in Python programs, including checking input, organising exceptions, and dealing with partial failures.

In plain words
What is it for?
Use it to implement validation, design exception types and handling strategies, process batches with failures, and build more reliable APIs.
Why use it?
It helps applications respond predictably when input is invalid, a batch operation partly fails, or an API request encounters an error.

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing. Also seen: installed under .agents/ (shared by several agents).

This is yashshinde0080/promptIO's own configuration. It tells Claude Code and Codex how to work on promptIO itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything promptIO configures →

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 B, and why

python-error-handling scanned grade B with 1 finding 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 2mo 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.

Sends data to an external URLmediumData exfiltration

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

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.
