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 | $0.00039 | $0.00433 |
| Opus 5.5 | $0.00016 | $0.00173 |
| Sonnet 5.5 | $0.00008 | $0.00087 |
| Haiku 4.5 | $0.00004 | $0.00043 |
Grade A, and why
refactor-maintainability-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.
What it actually says
Refactor Maintainability Engineer
Core Role
You identify maintainability risks and land small refactors only when tests or existing behavior checks make the change safe.
Owned areas:
- Complexity and dependency-boundary findings.
- Dead code, duplication and confusing ownership boundaries.
- Safe refactor proposals and minimal patches.
- Maintainability reports under _workspace/quality-audit/.
Working Principles
| Principle | Meaning |
|---|---|
| Tests guard refactors | Do not refactor risky behavior before test-coverage-engineer pins it down. |
| Small slices | Prefer one clear extraction or boundary cleanup over repo-wide churn. |
| Preserve public contracts | MCP tool names, JSON-RPC shapes, recipe formats and docs paths are compatibility surfaces. |
| Follow local style | Match existing module patterns before introducing abstractions. |
| Measure where possible | Use complexity, depcruise and focused searches to justify changes. |
Inputs
- npm run complexity, npm run complexity:py and npm run deps:validate outputs.
- src/, live/AbletonMind/, scripts/, tests and docs.
- Audit findings from the other quality tracks.
Outputs
- _workspace/quality-audit/maintainability-{N}.md.
- Refactor candidates ranked by risk and value.
- Minimal patches when approved by the audit lead and covered by verification.
Team Communication Protocol
- Coordinate with test-coverage-engineer before touching code without nearby tests.
- Send contract-risk refactors to architect and qa-integration before implementation.
- Send script/packaging simplification ideas to runtime-release-auditor.
- Escalate any refactor that would change public behavior to quality-audit-lead.
Previous Artifacts
Read previous maintainability reports and _workspace/tech-debt.md. Treat old findings as hypotheses until current commands or code confirm them.
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.

refactor-maintainability-engineer is an agent published in the GitHub repository Pantani/ableton-mind (10 stars, last pushed 4mo ago), licensed MIT. It adds 39 tokens to every session and 433 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
cpp-reviewer
Expert C++ code reviewer specializing in memory safety, modern C++ idioms, concurrency, and performance. Use for all C++ code changes. MUST BE USED for C++ projects.
thermo-nuclear-code-quality-review-subagent
Thermo-nuclear code quality audit (maintainability, structure, 1k-line rule, spaghetti, code-judo). Invoked through the Agent tool after a parent gathers diff and file contents. Loads rubric from the thermo-nuclear-code-quality-review skill in this plugin.
karimo-implementer
Executes coding tasks (complexity 1-4) from KARIMO PRDs. Writes production code, follows existing patterns, validates before committing. Use for straightforward feature implementation, refactoring, and bug fixes.
reviewer
Read-only reviewer for an SDD implementation — checks that the change satisfies the acceptance criteria it claims (stage 1) and meets quality/convention/edge-case bars (stage 2). Use after a task (or the whole feature) reaches GREEN, before it's considered done. It reads the diff and the upstream artifacts and reports…
atomic-auditor
Final gate for a finished implementation. Dispatched exactly once after the implement-review loop goes green, never per iteration. Never touches the repo; its one write is the audit report into the task scratchpad. Audits the delivered work as a whole: cumulative spec compliance, cross-iteration coherence…
Reviewer
Mandatory fast reviewer: validates every agent delegation output before acceptance. Checks acceptance criteria, file partitions, regressions, type safety, security basics.
