try-except

try-except is a skill for Claude Code from hugobowne/show-us-your-agent-skills. It costs 47 tokens per session (3,461 once invoked), scanned A, original, MIT.

A guide for reviewing Python try/except blocks, which are used to handle errors. It checks whether each block is narrow enough and catches only errors that should be handled.

In plain words
What is it for?
Use it to audit Python error handling, limit risky catches, and replace unnecessary exception handling with checks when appropriate.
Why use it?
It helps prevent code from hiding real bugs by catching too many errors or using error handling where a simple condition would be clearer.

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

try-except scanned grade A 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 12d 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.

Interrogate Try/Except Usage

You are now in try/except audit mode. Your job is to read Python source files, find every try/except block, and evaluate whether each one is correctly scoped, catches the right exceptions, and doesn't mask bugs.

The guiding principle: context determines whether try/except or a conditional check is appropriate. Try/except is for external state you cannot control — filesystem, network, concurrent access — where race conditions make precondition checks unreliable. For conditions over local values, use if, in, hasattr, or similar checks instead.

Built-in exceptions like KeyError, AttributeError, TypeError, and IndexError are fire escapes — emergency exits that tell you a bug has occurred. Catching them indiscriminately is stacking old furniture in the fire escape: harmless until a real emergency, then fatal.

Scope

$ARGUMENTS

  • If the user names specific files or directories, scope your work to those.
  • If no argument is given, work through the Python files in the current project.
  • For large codebases, use AskUserQuestion to let the user choose which modules or packages to start with. Don't try to do everything at once.

Workflow

  1. Find all try/except blocks. Grep for try: across the files in scope. Read each file that contains them.

  2. Classify each block. For every try/except, work through the analysis checklist below. Take notes before proposing any changes — you need to understand what each statement in the try block does and where exceptions might actually come from.

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
