add-tool

add-tool is a skill for Claude Code, Codex from caiwuu/Riot. It costs 54 tokens per session (1,692 once invoked), scanned C, original, no licence file.

A guide for adding a model-callable tool to Riot, including its interface, input schema, description, registration, error handling, and permission flags. A model-callable tool is an operation an AI model can request through the application’s tool API.

In plain words
What is it for?
Use it when defining a new Riot tool, implementing its required methods, converting failures into model-readable results, and deciding whether it is read-only or safe for concurrent use.
Why use it?
It helps prevent subtle failures where a tool compiles but reports the wrong permissions, exposes incomplete instructions, or silently handles errors in an unsafe way.

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 C, and why

add-tool scanned grade C 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 8d 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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.
