At a glance

Verify implementation code against a specific CodePlan step, checking scope, idempotency state, changed files, completion criteria, and progress.md accuracy.

  • Works in 2 steps: ../_shared/codeplan/core.md → ../_shared/codeplan/step-contract.md
  • The user asks to review applied code
  • SKILL.md covers Shared Contract, Purpose, Required Reads and Verification Focus, plus 1 more section
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Cp Verify is an agent skill from tangziwen/CubeMiniGame. Verify implementation code against a specific CodePlan step, checking scope, idempotency state, changed files, completion criteria, and progress.md accuracy. Use when the user asks to review applied code, verify step implementation, audit a completed step, or check whether progress should be marked complete.

Its SKILL.md is about 460 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).

The repository describes itself as: HomeBrew C++ 3D Game Engine based on OpenGL & Vulkan. The licence is MIT.

When your agent uses it

  • The user asks to review applied code
  • Verify step implementation
  • Audit a completed step
  • Check whether progress should be marked complete

Example prompts

  • “/cp-verify”

Workflow steps

2 steps, taken from the first numbered list in SKILL.md.

  1. ../_shared/codeplan/core.md
  2. ../_shared/codeplan/step-contract.md

What it can do on your machine

Read from SKILL.md and the folder at commit 33b364c. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Cp Verify loads about 463 tokens when it runs. Until then it costs about 80 tokens; SKILL.md has 199 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~80
When it runs · the whole SKILL.md, loaded when a task matches
~463

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

CodePlan Verify

Shared Contract

Before acting, read:

  1. ../_shared/codeplan/core.md
  2. ../_shared/codeplan/step-contract.md

Purpose

Review implemented code against design.md, progress.md, and a specific stepX.md. This is code review for applied work, not planning review.

Do not modify code during verification unless the user explicitly asks.

Required Reads

Read:

  1. AGENTS.md
  2. design.md
  3. progress.md
  4. the requested or inferred stepX.md
  5. files listed in File Operations
  6. relevant diffs or changed files

Read other steps only when the current step explicitly depends on them.

Verification Focus

Prioritize:

  • code that does not satisfy Completion Criteria
  • edits outside File Operations
  • File Operations lists that do not cover all actual changed files
  • File Operations lists that are too vague or incomplete to support reliable scope verification
  • missing added files or stale deleted files
  • partially applied changes marked complete
  • future-step work accidentally included
  • behavior that violates Preserved Behavior
  • missing progress or verification notes
  • build/test claims that were not actually run

Output

Lead with findings, ordered by severity, with file and line references when possible.

If no issues are found, say the implementation appears consistent with the step and list any residual risk.

Do not update progress.md unless the user explicitly asks you to reconcile status.
