It explains the repository layout, important commands, build outputs, and rules for editing each part safely.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: positional $N argument; mentions AGENTS.md; mentions OpenCode.

This is zhensherlock/protocol-launcher's own configuration. It tells Codex and OpenCode how to work on protocol-launcher 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 protocol-launcher 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

protocol-launcher 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.

AGENTS.md - Protocol Launcher

Repo Shape

  • PNPM workspace + Turbo monorepo; main CI uses Node 22 and packageManager is [email protected] (npm-publish builds with Node 22, then publishes the packed tgz with Node 24).
  • Workspaces are packages/shared (qs, encodeUrlPayload), packages/protocol-launcher (published URL generator library), apps/docs (VitePress EN/ZH docs), and apps/promo-video (HyperFrames composition).
  • The root package and library package are both named protocol-launcher; use path filters like pnpm --filter ./packages/protocol-launcher build, not name filters.
  • Respect nested workspace instructions before editing package/app code: packages/shared/AGENTS.md, packages/protocol-launcher/AGENTS.md, apps/docs/AGENTS.md, and apps/promo-video/AGENTS.md.
  • Build outputs are ignored (dist, coverage, apps/docs/.vitepress/dist, apps/docs/.vitepress/cache, .turbo, apps/*/renders, apps/*/.thumbnails, apps/*/.waveform-cache); do not edit generated output.

Commands That Matter

  • Install: pnpm install.
  • Root dev loop: pnpm dev runs Turbo with --filter=./apps/*..., so docs, promo-video, and dependency package watchers start together. Use focused dev commands when you only need one app.
  • Focused dev: pnpm --filter ./apps/docs dev for VitePress, pnpm --filter ./apps/promo-video dev for HyperFrames preview.
  • CI-equivalent build/test: pnpm build then pnpm coverage; the build workflow runs both and deploys apps/docs/.vitepress/dist.
  • Root pnpm build only filters ./apps/docs...; promo video is separate via pnpm build:promo, pnpm check:promo, and pnpm render:promo.
  • Focused builds: pnpm --filter ./packages/shared build, pnpm --filter ./packages/protocol-launcher build, pnpm --filter ./apps/docs build.
  • Tests: pnpm test for all Vitest projects; focus with pnpm test packages/protocol-launcher/tests/vscode.test.ts, pnpm test vscode, or pnpm test -t "test name".
  • Coverage gate: pnpm coverage matches the build workflow's test step.
  • Formatting/linting: there is no root lint script; use npx biome check . or npx biome check --write .. Pre-commit only runs biome check --write on staged packages/**/*.{ts,js}.
  • Type checking: do not use bare npx tsc --noEmit from the root; there is no root tsconfig.json and tsconfig.root.json is the shared base. Use package builds or npx tsc -p packages/protocol-launcher/tsconfig.json --noEmit.

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.
