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.

What it costs to keep this loaded
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 | $0.00067 | $0.00962 |
| Opus 5 | $0.00034 | $0.00481 |
| Sonnet 5 | $0.00013 | $0.00192 |
| Haiku 4.5 | $0.00007 | $0.00096 |
Grade A, and why
wax-performance-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 8d 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 — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Wax Performance Audit
Overview
Use this skill to benchmark Wax changes, isolate the hottest code path, and separate real regressions from noisy samples.
The repo builds with Swift 6.1 and StrictConcurrency enabled, so audit for Swift 6.2 concurrency risks without assuming 6.2-only language mode.
Workflow
- Name the symptom precisely: latency regression, memory growth, file bloat, or Swift concurrency diagnostics.
- Pick the narrowest benchmark or test file that exercises the path.
- Run a baseline and candidate with the same environment and scale.
- Collect wall time plus memory or file-growth metrics when the issue is not purely CPU-bound.
- Inspect the smallest relevant actor boundary, task group, cache, or I/O path.
- Report the evidence, the bottleneck, and the smallest safe fix.
Benchmark Selection
Use references/benchmark-workflow.md for the command matrix, environment flags, and benchmark map.
Prefer these repo entry points when they match the symptom:

What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

wax-performance-audit is a skill published in the GitHub repository christopherkarani/Wax (788 stars, last pushed 2d ago), licensed Apache-2.0. It adds 67 tokens to every session and 962 once invoked, about $0.0003 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.
