agent-schema-refactorer

agent-schema-refactorer is an agent for Claude Code from yaleh/meta-cc. It costs 35 tokens per session (2,186 once invoked), scanned A, original, MIT.

An API schema refactoring guide for safely reordering parameters and improving schema structure. An API schema describes the inputs that software services accept.

In plain words
What is it for?
It helps inspect JSON, OpenAPI, Swagger, and GraphQL schemas, identify parameters to reorder, plan changes, run tests, check compilation, and document the result.
Why use it?
It helps improve readability without changing how existing clients work, while checking that the format supports safe reordering.

Agent for Claude Code

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

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-schema-refactorer 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 6d 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.

agent-schema-refactorer is an agent published in the GitHub repository yaleh/meta-cc (21 stars, last pushed 15d ago), licensed MIT. It adds 35 tokens to every session and 2,186 once invoked, about $0.0002 per session on Opus 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.
