agentic-rd-skill: Instructions file for Codex

AGENTS.md

agentic-rd-skill AGENTS.md is an instructions file for Codex, OpenCode from TheStreamCode/agentic-rd-skill. It costs 1,439 tokens per session, scanned A, original, MIT.

Repository instructions for a portable AI skill and its Node.js command-line workflow. They define which files are authoritative, how the workflow works, and which project rules must remain true.

In plain words
What is it for?
Use them when modifying the agentic-rd-skill package, its workflow CLI, documentation, templates, tests, or repository-wide instructions.
Why use it?
They help contributors keep documentation, executable behavior, templates, and tests in agreement. They also clarify which files are product source and which are only local working artifacts.

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

This is TheStreamCode/agentic-rd-skill's own configuration. It tells Codex and OpenCode how to work on agentic-rd-skill 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 agentic-rd-skill 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

agentic-rd-skill 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.

Repository Instructions

These instructions apply to the entire repository. Preserve narrower instructions if a future subdirectory adds its own AGENTS.md.

Purpose And Sources Of Truth

This repository publishes a portable Agent Skill plus a dependency-free Node.js workflow CLI.

  • skills/agentic-rd-skill/ is the installable package.
  • skills/agentic-rd-skill/SKILL.md is the concise activation and operating contract.
  • skills/agentic-rd-skill/references/workflow.md is the detailed workflow/state reference.
  • skills/agentic-rd-skill/scripts/rd.mjs is the executable state-machine implementation.
  • skills/agentic-rd-skill/assets/ contains the canonical artifact templates.
  • README.md documents public behavior and installation.
  • evals/ contains dated evidence. Historical snapshots must not be presented as current measurements.
  • project-brief.md and work/ are ignored local dogfood artifacts, not tracked product source.

When documentation and runtime behavior disagree, verify the CLI and tests, then update every affected source of truth in the same change.

Repository Invariants

  • Support Node.js 20 or newer and keep the installable skill free of runtime dependencies.
  • Keep portable frontmatter provider-neutral; never add host-specific allowed-tools or implicit external authority.
  • Preserve phase order: setup, evidence, plan, execution, results, cross-review, stage gate, final.
  • New runs use workflow contract 1.1. Existing workflow 1.0 state remains readable; v0.3 workspaces are preserved and rejected rather than migrated.
  • Setup remains in_progress until the filled brief and run log pass their artifact contracts.
  • State-mutating commands validate the current global state and the candidate next state before writing. The documented stale-final recovery is the only scoped repair exception.
  • validate distinguishes valid-incomplete, valid-complete, and invalid state. Structural validation is not semantic assurance.
  • Stage-gate approval requires at least 8/10, no zero dimension, and zero blockers.
  • A requested revision must retain its ID and be resolved by an upstream artifact change or an explicit no-change disposition.
  • package.json is the single source of truth for the release version. SKILL.md metadata, CITATION.cff, the README version badge, and a dated CHANGELOG.md release section must match it; npm run validate fails on any partial bump.
  • Do not hardcode the release version anywhere else. Scripts that need it must read it from package.json or the shipped SKILL.md frontmatter.
  • The CLI is single-writer. Do not introduce concurrent state mutation without a designed locking/generation protocol and cross-platform tests.
  • Preserve atomic state replacement, managed-path containment, symlink rejection, non-overwrite behavior, and explicit exit classes.
  • Preflight the complete initialization layout before the first scaffold write; a late path conflict must leave earlier missing files untouched.
  • Keep currentPhase equal to the latest non-pending phase and keep stage-gate score, dimensions, blockers, and decision metadata consistent with the gate status.
  • Treat profile/option names as exact whitelist members rather than inherited object keys, and keep paid-tool, credentialed-system, and external-write state budgets fail-closed.
  • Never convert skipped or zero-execution host checks into a pass.

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.
