development-workflow

development-workflow is a skill for Claude Code from metaschema-framework/claude-plugins. It costs 28 tokens per session (1,722 once invoked), scanned A, original, CC0-1.0.

Development workflow guidance for repositories that use the Metaschema framework. It covers test-driven development, where tests are written before or alongside code, plus planning, debugging, and review practices.

In plain words
What is it for?
Use it when planning framework changes, writing tests, investigating bugs, following repository procedures, or preparing code for review.
Why use it?
It gives contributors a consistent way to make changes, verify them, and work through pull-request feedback.

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

development-workflow 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.

The opening of the file, as written. The whole thing — 204 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Development Workflow

Scope: This document describes development workflows for AI agents (Claude + superpowers plugin) and automated code review. Human developers should adapt these TDD, parallel-execution, and review principles to their tooling and IDE.

Skill Usage Protocol (MANDATORY)

Before responding to ANY task, complete this checklist:

  1. Check for relevant skills - Does any skill match this request?
  2. If skill exists → Use Skill tool to load and run it
  3. Announce usage - "I'm using [skill] to [action]"
  4. Follow skill exactly - Don't adapt away the discipline

Checklist Tracking Rule

If a skill has a checklist, create TodoWrite todos for EACH item. Never:

  • Work through checklists mentally
  • Skip todos "to save time"
  • Batch multiple items into one todo

Common Rationalizations (RED FLAGS)

If you think any of these, STOP and check for skills:

  • "This is just a simple question"
  • "Let me gather information first"
  • "This doesn't need a formal skill"
  • "The skill is overkill for this"
  • "I'll just do this one thing first"

Why: Skills document proven techniques. Not using available skills = repeating solved problems.


Test-Driven Development (MANDATORY - BLOCKING)

ALL code changes MUST follow TDD. No exceptions. This is BLOCKING.

The Iron Law of TDD

TESTS MUST BE WRITTEN AND FAIL BEFORE ANY IMPLEMENTATION CODE EXISTS

This is non-negotiable. Implementation code written before tests is a violation.

The TDD Cycle

  1. Write the test first - Before writing any implementation code
  2. Watch it fail - Run the test to verify it fails for the right reason
  3. Write minimal code - Implement just enough to make the test pass
  4. Refactor - Clean up while keeping tests green
  5. Repeat - For each new behavior

Enforcement Gate

Before writing ANY implementation code, you MUST have:

  • A test file created for the new functionality
  • At least one failing test that exercises the code path
  • Verification that the test fails for the expected reason (not a syntax error)

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.
