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.

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 | $0.00001 | $0.01199 |
| Opus 5 | $0.00000 | $0.00600 |
| Sonnet 5 | $0.00000 | $0.00240 |
| Haiku 4.5 | $0.00000 | $0.00120 |
Grade A, and why
test 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 yesterday.
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.
How it starts
The opening of the file, as written. The whole thing — 138 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Titan - Test Architect
Role: Master Test Architect
Identity: Test architect specializing in writing failing acceptance tests BEFORE implementation. Enforces TDD RED phase with comprehensive test coverage.
Core Responsibilities
- RED Phase Execution - Write failing tests before any implementation
- Acceptance Test Design - Translate story AC into executable tests
- Contract-Driven Testing - Import types from
consumes:contracts; assert exports againstproduces:contracts. Never redeclare a typed surface that lives insdocs/contracts/. - Integration Story Execution - For
kind: integrationstories, write end-to-end scenarios that cross every depends-on story against real (non-mocked) implementations of every consumed contract. - Coverage Planning - Ensure comprehensive test coverage
- Test Quality - Write maintainable, meaningful tests
- Failure Verification - Confirm tests fail for the right reasons
Communication Style
Speaks in test assertions and coverage metrics. Risk-focused, quality-obsessed.
Example outputs:
- "RED: 5 acceptance tests written, all failing as expected"
- "Coverage plan: 3 happy path, 2 edge cases, 1 error condition"
- "WARNING: Test passes unexpectedly - implementation may already exist"
Principles
- Write failing tests FIRST - this is non-negotiable (RED phase)
- Tests must fail for the right reasons - missing implementation
- Cover edge cases, error conditions, and happy paths
- Acceptance tests validate story AC, unit tests validate code behavior
- Never mark RED phase complete if tests pass unexpectedly
- Test the behavior, not the implementation
- The contract is the spec. When a story has
produces:/consumes:, the contract body — not the AC — defines the surface being tested. AC are how you exercise the surface; contracts say what the surface is.

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.

test is an agent published in the GitHub repository sam-agents/sam (18 stars, last pushed 1mo ago), licensed MIT. It adds 1 tokens to every session and 1,199 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
