What it does
Perf Theory Gatherer is an agent skill from composio-community/awesome-claude-plugins. Use when generating performance hypotheses backed by git history and code evidence.
Its SKILL.md is about 210 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Git workflow. The repository describes itself as: A curated list of Plugins that let you extend Claude Code with custom commands, agents, hooks, and MCP servers through the plugin system.
When your agent uses it
- Generating performance hypotheses backed by git history and code evidence
- Tasks that involve Git workflow
Example prompts
- “/perf-theory-gatherer”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Review recent git history (scope to relevant paths when possible).
- Identify code paths involved in the scenario (repo-map or grep).
- Produce up to 5 hypotheses with evidence + confidence.
What it can do on your machine
Read from SKILL.md and the folder at commit e521f7a. 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
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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
Perf Theory Gatherer loads about 208 tokens when it runs. Until then it costs about 26 tokens; SKILL.md has 66 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 66 words (~208 tokens).
