tdd-init

A setup command that adds a TDD pipeline configuration template to a project's CLAUDE.md file. TDD means writing tests around expected behavior as part of development.

In plain words
What is it for?
Use it when preparing a project for the TDD pipeline. Then provide its test commands, file patterns, build steps, full checks, and language-specific guidance.
Why use it?
It creates the required project settings in the expected format and avoids duplicating them if they are already present.

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

tdd-init 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 2d 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.

What it actually says

/tdd-init

Add TDD pipeline configuration to this project's CLAUDE.md.

Procedure

1. Read the configuration fragment

Read the file at ${CLAUDE_PLUGIN_ROOT}/docs/claude-md-fragment.md. This contains the TDD pipeline configuration template formatted as a CLAUDE.md section.

2. Check current CLAUDE.md

  • If no CLAUDE.md exists in the project root, create one with just a # CLAUDE.md header followed by the fragment content.
  • If CLAUDE.md exists, check if it already contains "TDD Pipeline Configuration". If so, report "TDD pipeline configuration already present" and stop.
  • If CLAUDE.md exists but lacks the configuration, append the fragment content to the end of the file.

3. Report result

Tell the user what you did:

  • "Created CLAUDE.md with TDD pipeline configuration"
  • "Added TDD pipeline configuration to existing CLAUDE.md"
  • "TDD pipeline configuration already present in CLAUDE.md"

4. Next steps

Tell the user to fill in the template values:

  • Test command for individual modules
  • Source and test file path patterns
  • Build integration steps
  • Full test and lint commands
  • Any language-specific agent context

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.
