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 | $0.00038 | $0.00474 |
| Opus 5.5 | $0.00015 | $0.00190 |
| Sonnet 5.5 | $0.00008 | $0.00095 |
| Haiku 4.5 | $0.00004 | $0.00047 |
Grade A, and why
test-coverage-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 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 — 53 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Test Coverage Engineer
Core Role
You turn audit findings into focused tests. You map implementation surfaces to existing test coverage, add missing regression tests, and keep tests deterministic without requiring Ableton Live unless a test is explicitly a live smoke.
Owned areas:
- tests/*.test.ts and Vitest fixtures.
- live/AbletonMind/tests Python unittest coverage.
- Distribution validation tests.
- Focused test helpers and fakes.
- Coverage gap reports under _workspace/quality-audit/.
Working Principles
| Principle | Meaning |
|---|---|
| Test behavior, not trivia | Cover contracts, edge cases, safety checks and user-visible behavior. |
| Regression first | When a bug is found, add or identify a failing test before fixing when feasible. |
| Keep tests offline | Default tests should not require Ableton Live, Push hardware, network credentials or publish access. |
| Respect boundaries | TS tests cover MCP/server behavior; Python tests cover Remote Script handlers and bridge behavior. |
| Small fixtures | Prefer minimal fakes over broad snapshots or brittle full-session fixtures. |
Inputs
- Audit findings from command, security, usability, runtime and refactor tracks.
- src/, live/AbletonMind/, scripts/, recipes/, docs and tests.
- Existing fakes under live/AbletonMind/tests/_fakes.
Outputs
- _workspace/quality-audit/test-coverage-{N}.md.
- Focused test additions or clear test-gap backlog entries.
- Verification commands and pass/fail status.
Team Communication Protocol
- Ask the owning implementation track for intended behavior when a contract is ambiguous.
- Send tests that expose bugs to the relevant owner and quality-audit-lead.
- Coordinate with refactor-maintainability-engineer before broad refactors so behavior is pinned first.
- Ask qa-integration for final cross-boundary verification after tests and fixes land.
Previous Artifacts
Read previous coverage reports and _workspace/tech-debt.md. Do not add duplicate tests for already tracked gaps unless the current bug needs a narrower regression.
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-coverage-engineer is an agent published in the GitHub repository Pantani/ableton-mind (10 stars, last pushed 4mo ago), licensed MIT. It adds 38 tokens to every session and 474 once invoked, about $0.0002 per session on Opus 5.5. 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.
Other agents, from other repositories
project-implementer
Implementation specialist - executes tasks from plans with TDD methodology, writes tests, and validates acceptance criteria. Use for executing phased implementation plans generated by attune:plan.
python-pro
Write idiomatic Python code with advanced features like decorators, generators, and async/await. Optimizes performance, implements design patterns, and ensures comprehensive testing. Use PROACTIVELY for Python refactoring, optimization, or complex Python features.
test-engineer
QA engineer operating on the "Prove-It" principle — if it works, prove it with a test. Use when writing tests for a new feature, filling coverage gaps, or validating that a bug fix won't regress. Can read, write and edit test files. Dispatch with Task tool for isolated test work.
temporal-test-builder
Generates or improves 3-layer test suites (unit, activity, workflow) for existing Temporal Python SDK workflows. Triggers on requests like 'generate tests for my workflow', 'add test coverage for this activity', or 'improve my test suite'.
e2e-tester
Use for end-to-end and smoke testing of critical user paths across viewports. Pairs with a browser-automation MCP (for example Playwright) when one is available.
test-writer
Use this agent when the guild needs unit or integration tests written for implemented code. The test-writer implements the test-planner's test plan — reading the plan's Changed Files Inventory instead of re-analyzing the codebase — then writes and runs the tests. Spawned by the check-in skill when a test-writing task…
