cursor-implements: Instructions file for Codex

AGENTS.md

cursor-implements AGENTS.md is an instructions file for Codex, OpenCode from ymhhh/cursor-implements. It costs 820 tokens per session, scanned A, original, MIT.

Project instructions for a code workflow that separates planning, implementation, testing, review, security checks, and verification. AGENTS.md is a file that tells coding agents how to work in a repository.

In plain words
What is it for?
Use it to plan changes, wait for approval before coding, implement work with rollback evidence, run tests, review code, audit security, and prepare releases.
Why use it?
It gives the agent a defined sequence and assigns different checks to specific roles, reducing missed validation steps.

This is ymhhh/cursor-implements's own configuration. It tells Codex and OpenCode how to work on cursor-implements 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 cursor-implements 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

cursor-implements 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 1mo 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 — cursor-implements workflow

Default guidance for agents working in a project that copied this kit’s .cursor/.

Mainline

  1. Use planner to produce IMPLEMENTATION_PLAN.md (or copy templates/IMPLEMENTATION_PLAN.md).
  2. Wait for the user to say ACT (or “开始实现” / “按计划执行”).
  3. Use implementer to execute plan steps (each step: evidence + rollback).
  4. Validate with test-runner, code-reviewer, security-auditor, verifier.
  5. Ship with pr-author / release-manager as needed.

Use orchestrator for copy-paste prompt chains and role selection.

Role RACI (quick)

Concern Own Consult
Plan / work order planner orchestrator
General code execution implementer FE/BE specialists
Frontend / a11y / UI frontend-engineer ux-reviewer, implementer
Backend / API reliability backend-engineer api-designer, implementer
API contract design api-designer FE/BE
Automated tests test-runner qa
Manual / regression cases qa test-runner, verifier
Correctness / maintainability review code-reviewer security-auditor
Auth / secrets / vuln patterns security-auditor code-reviewer
Acceptance Pass/Fail/Blocked verifier plan + test evidence
Root-cause / minimal fix debugger test-runner
Behavior-preserving structure refactorer test-runner, code-reviewer
PR text pr-author release-manager
Rollout / flags / rollback release-manager pr-author

Slots: implementer is the default executor. Call frontend-engineer / backend-engineer when domain constraints (a11y, idempotency, observability) matter. code-reviewer covers broad quality; security-auditor is security-first; qa is human-reproducible checklists.

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.
