canvas-cli AGENTS.md

canvas-cli AGENTS.md is an instructions file for Codex, OpenCode from jjuanrivvera/canvas-cli. It costs 2,825 tokens per session, scanned A, original, MIT.

Repository instructions for Canvas CLI, a Go command-line program that communicates with the Canvas learning-management system. They document its build, test, formatting, linting, installation, setup, and project structure.

In plain words
What is it for?
Use them when building, testing, linting, formatting, installing, or preparing Git hooks for Canvas CLI.
Why use it?
They give coding agents the exact commands and checks expected in this repository. Pre-commit checks also help catch formatting problems, static-analysis warnings, test failures, and race conditions before a commit.

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

canvas-cli AGENTS.md scanned grade A 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.

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 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.
