build-perf-baseline

build-perf-baseline is a skill for Claude Code from F-U-S-E-E/FuseDevelopmentGroup. It costs 116 tokens per session (2,861 once invoked), scanned C, original, AGPL-3.0.

A guide for measuring and improving the time MSBuild, the build system used by .NET projects, takes to compile software.

In plain words
What is it for?
Use it to investigate slow .NET builds, record before-and-after timings, and apply build settings such as MSBuild Server or static graph builds.
Why use it?
It helps show whether a build is slow and whether a change actually makes it faster by comparing cold, warm, and no-op builds.

Token cost

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.

Security

Grade C, and why

build-perf-baseline scanned grade C 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 6d 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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

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.

build-perf-baseline is a skill published in the GitHub repository F-U-S-E-E/FuseDevelopmentGroup (22 stars, last pushed 12d ago), licensed AGPL-3.0. It adds 116 tokens to every session and 2,861 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
