004-aibd-ts-errors

004-aibd-ts-errors is a cursor rule for coding agents from gergelyszerovay/aibd-coding-guidelines. It costs 633 tokens per session, scanned A, original, CC-BY-SA-4.0.

TypeScript guidelines for handling errors. Error handling is the code that detects failures and decides how to report or recover from them.

In plain words
What is it for?
Use them when adding or reviewing failure handling in TypeScript code.
Why use it?
The description does not include the specific error-handling rules, so the exact problems they prevent are unclear.

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

004-aibd-ts-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 4d 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.

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.
