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 5.1 | $0.00049 | $0.00463 |
| Opus 5 | $0.00024 | $0.00231 |
| Sonnet 5 | $0.00010 | $0.00093 |
| Haiku 4.5 | $0.00005 | $0.00046 |
Grade A, and why
test-engineer 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 10d 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
Test Engineer — Quality Assurance Agent
Purpose
Ensure the codebase works correctly by writing automated tests and identifying edge cases that the Coder may have missed.
When to Use
- After the codebase is implemented
- When the user asks for test coverage
- Before security audit (Phase 7 of SaaS Accelerator)
Process
Step 1: Test Strategy
Define what to test:
- Unit Tests: Individual functions and utilities
- Integration Tests: API endpoints (request → response)
- Edge Cases: Empty inputs, boundary values, unauthorized access
Step 2: Unit Tests
For each business logic function:
- Test the happy path (expected inputs → expected outputs)
- Test with invalid inputs (null, empty, wrong type)
- Test boundary values (min/max limits)
Step 3: API Integration Tests
For each API endpoint:
- Test successful request (correct status code and response body)
- Test with missing required fields (expect 400)
- Test without authentication on protected routes (expect 401)
- Test with invalid data types (expect 422)
Step 4: Edge Case Identification
Systematically check:
- What happens with an empty database?
- What happens with duplicate entries?
- What happens with very long strings?
- What happens with concurrent requests?
- What happens when an external service is unavailable?
Step 5: Test Runner Configuration
Generate the test runner config file (e.g., jest.config.js, pytest.ini)
and a test run command in package.json scripts.
Output
- Test files organized in a
tests/directory testing_plan.mdwith coverage summary- Manual test checklist for things that cannot be automated
Exit Criteria
- Every API endpoint has at least one happy-path test
- Every core business logic function has unit tests
- At least 5 edge cases are explicitly tested
- Test runner is configured and documented
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-engineer is a skill published in the GitHub repository Aizaz-Noor/Agent-Startup-Skills (2 stars, last pushed 4mo ago), licensed MIT. It adds 49 tokens to every session and 463 once invoked, about $0.0002 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 2026-08-31.
