agent-parameter-categorizer

agent-parameter-categorizer is an agent for Claude Code from yaleh/meta-cc. It costs 32 tokens per session (2,402 once invoked), scanned A, original, MIT.

An API-parameter sorting guide that assigns each parameter to a fixed tier using a decision tree. An API is a defined way for software systems to communicate.

In plain words
What is it for?
It helps categorize parameters as required inputs, filters, range settings, output controls, or standard options, then order them, explain the decisions, and verify consistent results.
Why use it?
It removes inconsistent manual ordering and makes the same kind of parameter appear in the same place across tools.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md).

Good fit It helps categorize parameters as required inputs, filters, range settings, output controls, or standard options, then order them, explain the decisions, and verify consistent results.

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

agent-parameter-categorizer 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 1mo 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.

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.

agent-parameter-categorizer is an agent published in the GitHub repository yaleh/meta-cc (22 stars, last pushed 18d ago), licensed MIT. It adds 32 tokens to every session and 2,402 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
