What is learn-opencode-agent AGENTS.md?

Repository instructions that tell a coding agent how to work in the qqzhangyanhua/learn-opencode-agent project, including which documentation to read, how to make changes, and how to run checks.

Use them when modifying this VitePress book site to locate relevant documentation, follow the expected workflow, run validation scripts, and report changes and remaining risks.

They give the agent the project’s local rules and reduce the risk of editing the wrong files, skipping tests, or making high-risk changes without review.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00864	$0.00864
Opus 5.5	$0.00346	$0.00346
Sonnet 5.5	$0.00173	$0.00173
Haiku 4.5	$0.00086	$0.00086

Security

Grade A, and why

learn-opencode-agent AGENTS.md 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 2mo 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.

Default Agent Workflow

Understand the task and check current workspace state.
Search for relevant files before editing.
Make the smallest safe change.
Add or update tests/checks when behavior changes.
Run ./scripts/check.sh or the narrower verified command listed in docs/testing.md.
Report changed files, validation results, and remaining risks.

Do Not

Edit generated files directly.
Modify secrets or local environment files.
Change deployment, infrastructure, permissions, public API examples, navigation contracts, or generated/cache artifacts without calling out the risk.
Hide failing or skipped checks.

Large or High-Risk Changes

Use docs/agent-plan-template.md before editing. Stop after the plan for high-risk areas and ask for human review.

Project Structure & Module Organization

This repository is a VitePress-based book site. Main content lives in docs/, with chapter folders such as docs/01-agent-basics/, practice lessons in docs/practice/, and intermediate chapters in docs/intermediate/. Interactive source examples live in practice/ as runnable TypeScript entry files like p01-minimal-agent.ts. Theme code and UI components live under .vitepress/, especially .vitepress/theme/components/ and .vitepress/theme/data/. Validation and release checks are script-driven from scripts/check-*.mjs.

Build, Test, and Development Commands

bun install: install dependencies.
bun run dev: start the local VitePress dev server.
bun run build: build the static site.
bun run preview: preview the built site locally.
bun run typecheck: run TypeScript checks for .vitepress/.
bun run check:content: validate document structure and required metadata.
bun run check:practice: verify practice entry pages.
bun run build:strict: run the full validation pipeline before release.

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.
