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 | $0.00102 | $0.24517 |
| Opus 5.5 | $0.00041 | $0.09807 |
| Sonnet 5.5 | $0.00020 | $0.04903 |
| Haiku 4.5 | $0.00010 | $0.02452 |
Grade A, and why
optimization-audit 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 1,191 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Optimization Audit
A comprehensive optimization skill with two modes and a single tier:
Modes:
- Planning (before code exists) — performance strategy, capacity planning, scaling architecture, data access design
- Audit (on existing code) — scanning for performance anti-patterns, inefficient algorithms, N+1 queries, missing caching, concurrency issues, and resource waste
Single tier: Unlike the security and observability audits, optimization tools are overwhelmingly free/open-source (profilers, EXPLAIN, load testers, linters). Enterprise APM platforms are already covered by the observability-audit skill, so a Standard/Enterprise split would duplicate coverage.
Core question: "Is this system using resources efficiently?"
When to use this skill
- When the user says "optimization audit", "performance review", "find bottlenecks", "optimize this", "check efficiency", or "resource audit"
- Before designing a new system (planning mode) — to define performance strategy, capacity planning, and scaling architecture early
- On an existing codebase (audit mode) — to find and fix performance anti-patterns and resource waste
- Before a production deployment — to validate performance posture
- After adding new services, data pipelines, or performance-sensitive features
- When investigating production performance incidents or cost overruns
Mode detection
Determine which mode to operate in based on the project state:
| Signal | Mode | Rationale |
|---|---|---|
| User says "design for performance", "plan scaling", "capacity planning" | Planning | Architecture-level performance strategy |
| User says "audit", "optimize", "find bottlenecks", "performance review" | Audit | Code and infrastructure scanning |
| No source code exists yet (only docs, diagrams, RFCs) | Planning | Nothing to profile — design the strategy |
| Source code and/or infrastructure files exist | Audit | Concrete artifacts to analyze |
| Both code and a request to "plan performance" | Both | Run planning phases on architecture, audit phases on code |

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.

optimization-audit is a skill published in the GitHub repository karsten-s-nielsen/mad-scientist-skills (3 stars, last pushed 1mo ago), licensed MIT. It adds 102 tokens to every session and 24,517 once invoked, about $0.0004 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.
