ocr

ocr is a skill for Claude Code, Codex from trpc-group/trpc-agent-go. It costs 11 tokens per session (582 once invoked), scanned B, original, Apache-2.0.

A tool workflow for extracting text from image files with Tesseract, an optical character recognition system. It supports common image formats, many languages, optional image cleanup, and plain-text or JSON output with confidence scores.

In plain words
What is it for?
Use it to read text from local images or image URLs, choose one or more recognition languages, improve the input before recognition, or save results with confidence information.
Why use it?
It turns words shown in screenshots, scans, and photographs into text that can be searched or processed. Preprocessing and language selection can help with difficult images.

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 B, and why

ocr scanned grade B 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 4d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/ocr_url.py, scripts/ocr.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
