badman: Skill for Claude Code

.claude/skills/speckit-checklist/SKILL.md

speckit-checklist is a skill for Claude Code from Badminton-Apps/badman. It costs 19 tokens per session (4,576 once invoked), scanned A, a copy of speckit-checklist, Apache-2.0.

A requirements checklist generator for a software feature. The checklist reviews whether the written requirements are complete, clear, consistent, and ready to implement, rather than testing the finished code.

In plain words
What is it for?
It is for reviewing feature specifications and turning their quality checks into a concrete checklist.
Why use it?
It helps catch vague wording, missing edge cases, and undefined accessibility or behaviour requirements before development starts.

Skill for Claude Code

This is Badminton-Apps/badman's own configuration. It tells Claude Code how to work on badman 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 badman 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

speckit-checklist 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 3d 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.

Origin

This is a copy

98% identical to speckit-checklist — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Checklist Purpose: "Unit Tests for English"

CRITICAL CONCEPT: Checklists are UNIT TESTS FOR REQUIREMENTS WRITING - they validate the quality, clarity, and completeness of requirements in a given domain.

NOT for verification/testing:

  • ❌ NOT "Verify the button clicks correctly"
  • ❌ NOT "Test error handling works"
  • ❌ NOT "Confirm the API returns 200"
  • ❌ NOT checking if code/implementation matches the spec

FOR requirements quality validation:

  • ✅ "Are visual hierarchy requirements defined for all card types?" (completeness)
  • ✅ "Is 'prominent display' quantified with specific sizing/positioning?" (clarity)
  • ✅ "Are hover state requirements consistent across all interactive elements?" (consistency)
  • ✅ "Are accessibility requirements defined for keyboard navigation?" (coverage)
  • ✅ "Does the spec define what happens when logo image fails to load?" (edge cases)

Metaphor: If your spec is code written in English, the checklist is its unit test suite. You're testing whether the requirements are well-written, complete, unambiguous, and ready for implementation - NOT whether the implementation works.

User Input

$ARGUMENTS

You MUST consider the user input before proceeding (if not empty).

Pre-Execution Checks

Check for extension hooks (before checklist generation):

  • Check if .specify/extensions.yml exists in the project root.
  • If it exists, read it and look for entries under the hooks.before_checklist key
  • If the YAML cannot be parsed or is invalid, skip hook checking silently and continue normally
  • Filter out hooks where enabled is explicitly false. Treat hooks without an enabled field as enabled by default.
  • For each remaining hook, do not attempt to interpret or evaluate hook condition expressions:
    • If the hook has no condition field, or it is null/empty, treat the hook as executable
    • If the hook defines a non-empty condition, skip the hook and leave condition evaluation to the HookExecutor implementation
  • When constructing slash commands from hook command names, replace dots (.) with hyphens (-). For example, speckit.git.commit/speckit-git-commit.
  • For each executable hook, output the following based on its optional flag:
    • Optional hook (optional: true):
      ## Extension Hooks
      
      **Optional Pre-Hook**: {extension}
      Command: `/{command}`
      Description: {description}
      
      Prompt: {prompt}
      To execute: `/{command}`
      
    • Mandatory hook (optional: false):
      ## Extension Hooks
      
      **Automatic Pre-Hook**: {extension}
      Executing: `/{command}`
      EXECUTE_COMMAND: {command}
      
      Wait for the result of the hook command before proceeding to the Execution Steps.
      
  • If no hooks are registered or .specify/extensions.yml does not exist, skip silently

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.
