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 | $0.00244 | $0.04681 |
| Opus 5 | $0.00122 | $0.02341 |
| Sonnet 5 | $0.00049 | $0.00936 |
| Haiku 4.5 | $0.00024 | $0.00468 |
Grade B, and why
model-perf-engineer scanned grade B with 1 finding 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 2d 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.

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.

model-perf-engineer is an agent published in the GitHub repository murmur-io/murmur (9 stars, last pushed today), licensed AGPL-3.0. It adds 244 tokens to every session and 4,681 once invoked, about $0.0012 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
Other agents, from other repositories
collaboration
How coding agents (Claude Code, Codex, or any future harness) collaborate on this repo: who orchestrates, who implements, who reviews, and what each layer may touch. This is the map; the skills own the mechanics — never restate a skill's commands here or anywhere else (single owner per fact).
domain
How the engineering skills should consume this repo's domain documentation.
issue-tracker
Issues for this repo live on the Open Software platform (os-platform), org june — NOT GitHub Issues. GitHub Issues exist on the repo but are a legacy/watchdog surface, not the triage queue.
triage-labels
The skills speak in terms of five canonical triage roles. os-platform Issues have both statuses and labels; this repo maps roles across both axes.
flow-verifier
Runs the VZT Flow end-to-end verification ladder (build, tests, TTS-transcribe checks, clean-test latency, paste-test, daemon socket checks, overlay states) and reports real measured numbers — never estimates. Use before claiming a change works, before a release, or when asked to verify VZT Flow.
demo-agents
We need a steady flow of demo videos — X/Twitter, Reddit, YouTube Shorts, blog posts, App Store-style screen recordings — and we'd like to scale that without scheduling Daniel to record every clip by hand. This doc maps the content-creation agent landscape, names the gap between "synthetic video hype" and "scripted…
