CU-Tools: Skill for Claude Code

.github/skills/iterate-analyzer-schema.skill.md

iterate-analyzer-schema is a skill for Claude Code, Codex from jfilcik/CU-Tools. It costs 58 tokens per session (1,215 once invoked), scanned A, original, no licence file.

A method for improving Azure AI Content Understanding schemas through repeated, evidence-based experiments. A schema defines the fields an analyzer should extract from documents.

In plain words
What is it for?
Use it to tune extraction consistency, compare schema versions, measure regressions, and report the results of schema experiments.
Why use it?
It makes changes measurable by keeping an unchanged baseline, repeating tests, checking regressions, and promoting only improvements.

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing.

This is jfilcik/CU-Tools's own configuration. It tells Claude Code and Codex how to work on CU-Tools itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything CU-Tools configures →

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

iterate-analyzer-schema 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 3d 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.
