strikethroo: Instructions file for Codex

AGENTS.md

strikethroo AGENTS.md is an instructions file for Codex, OpenCode from e0ipso/strikethroo. It costs 1,085 tokens per session, scanned A, original, MIT.

Repository instructions for Strikethroo, a command-line tool that sets up and checks AI-agent workspaces. They cover setup, commands, development, and terminology.

In plain words
What is it for?
Using `init`, `export profile`, `serve`, and `validate`, plus the documented development and workspace procedures.
Why use it?
They give an agent the project-specific rules needed to build, test, run, and validate Strikethroo correctly.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md.

This is e0ipso/strikethroo's own configuration. It tells Codex and OpenCode how to work on strikethroo 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 strikethroo 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

strikethroo 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 6d 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.

How it starts

The opening of the file, as written. The whole thing — 52 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

Load and include ./AGENTS.local.md, it contains skill-specific instructions in a git-ignored file.

This file holds only what every task needs. Subsystem contracts, rationale, and gotchas live in the kenkeep knowledge base (loaded at the end of this file). Descend into the branch for the code you are about to touch before you change it.

Strikethroo is a CLI (init, update, export profile, serve, validate) plus seven harness-agnostic Agent Skills (st-*) that turn a work order into a plan, a task blueprint, and verified execution. User docs are in docs/; terms are in docs/glossary.md.

Commands

npm run build          # tsc, SPA type-check and build, skill bundles, skill prompts
npm test               # unit (Vitest) then e2e (Playwright); run `npx playwright install --with-deps chromium` once
npm run lint:fix
npm run security:check # audit-ci gate that CI runs
npm run dev            # watch mode; dev:serve and dev:web for the viewer
node dist/cli.js init --harnesses claude --destination-directory /tmp/test

Integration and e2e tests run the compiled output, so build before testing.

Rules any change can break

  • Design invariant. Negotiable configuration is Markdown, guarantees are compiled. Enforcement a user must not loosen goes in TypeScript, never in a hook. Read the design thesis before changing src/skill-prompts/ or src/skill-scripts/.
  • Never edit skills/ or dist-test/. skills/ is written only by the release; dist-test/ is local build output. Edit src/skill-prompts/ (read its AUTHORING.md first) and src/skill-scripts/. A pre-commit guard and CI enforce this.
  • Import boundaries. Nothing in src/skill-scripts/ imports src/validation/ or src/serve/. The SPA (src/web/) imports nothing from src/skill-scripts/. Crossings from src/serve/ and src/validation/ into src/skill-scripts/shared/ stay few and deliberate.
  • Dependencies. Frontend libraries stay in devDependencies. js-yaml stays in dependencies.
  • Workspace schema. Bump CURRENT_WORKSPACE_SCHEMA_VERSION (src/metadata.ts) only for an incompatible workspace shape change.
  • Words. "Strikethroo profile" (setup package) and execution_routing.profiles are different things. "Phase" means a blueprint task group only. Docs describe current state only.
  • Git. Do not skip hooks with --no-verify. The commit-msg hook rejects AI attribution trailers, and pre-commit runs the full test suite.

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.
