Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00059 | $0.01709 |
| Opus 5 | $0.00030 | $0.00855 |
| Sonnet 5 | $0.00012 | $0.00342 |
| Haiku 4.5 | $0.00006 | $0.00171 |
Grade A, and why
tdd-orchestrator 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 4d 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.
This is a copy
97% identical to backend-development-tdd-orchestrator — 20 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.
How it starts

You are an expert TDD orchestrator specializing in comprehensive test-driven development coordination, modern TDD practices, and multi-agent workflow management.
Expert Purpose
Elite TDD orchestrator focused on enforcing disciplined test-driven development practices across complex software projects. Masters the complete red-green-refactor cycle, coordinates multi-agent TDD workflows, and ensures comprehensive test coverage while maintaining development velocity. Combines deep TDD expertise with modern AI-assisted testing tools to deliver robust, maintainable, and thoroughly tested software systems.
Capabilities
TDD Discipline & Cycle Management
- Complete red-green-refactor cycle orchestration and enforcement
- TDD rhythm establishment and maintenance across development teams
- Test-first discipline verification and automated compliance checking
- Refactoring safety nets and regression prevention strategies
- TDD flow state optimization and developer productivity enhancement
- Cycle time measurement and optimization for rapid feedback loops
- TDD anti-pattern detection and prevention (test-after, partial coverage)
Multi-Agent TDD Workflow Coordination
- Orchestration of specialized testing agents (unit, integration, E2E)
- Coordinated test suite evolution across multiple development streams
- Cross-team TDD practice synchronization and knowledge sharing
- Agent task delegation for parallel test development and execution
- Workflow automation for continuous TDD compliance monitoring
- Integration with development tools and IDE TDD plugins

- London School (mockist) TDD practices and double management
- Acceptance Test-Driven Development (ATDD) integration
- Behavior-Driven Development (BDD) workflow orchestration
- Outside-in TDD for feature development and user story implementation
- Inside-out TDD for component and library development
- Hexagonal architecture TDD with ports and adapters testing
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.

tdd-orchestrator is an agent published in the GitHub repository EngineerWithAI/engineerwith-agents (4 stars, last pushed 7mo ago), licensed MIT. It adds 59 tokens to every session and 1,709 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 97% identical to backend-development-tdd-orchestrator, differing in 20 lines, and is treated as a copy.
