What it does
Extreme Software Optimization is an agent skill from pedronauck/skills. Profile-driven performance optimization with behavior proofs. Use when: optimize, slow, bottleneck, hotspot, profile, p95, latency, throughput, or algorithmic improvements.
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `references/ADVANCED.md`, `references/LANGUAGE-SPECIFIC.md` and `references/METHODOLOGY.md`).
It sits in Development, covering Performance optimization. The repository describes itself as: My personal favorite skills.
When your agent uses it
- Algorithmic improvements
- Tasks that involve Performance optimization
Example prompts
- “/extreme-software-optimization”
Requirements
- Python 3
What it can do on your machine
Read from SKILL.md and the folder at commit 0422940. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
rgcargogogit
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Extreme Software Optimization loads about 1.1k tokens when it runs, and up to ~16k if it reads all its reference files. Until then it costs about 51 tokens; SKILL.md has 315 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 315 words (~1,141 tokens).
