At a glance
A skill your agent uses when profiling CPU/memory hot paths, generating flame graphs, or capturing JFR/perf evidence.
- Profiling CPU/memory hot paths
- SKILL.md covers Required Rules, Output Format and Constraints
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
- Generating flame graphs
What it does
Perf Profiler is an agent skill from composio-community/awesome-claude-plugins. Use when profiling CPU/memory hot paths, generating flame graphs, or capturing JFR/perf evidence.
Its SKILL.md is about 180 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 Performance optimization. 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
- Profiling CPU/memory hot paths
- Generating flame graphs
- Capturing JFR/perf evidence
Example prompts
- “/perf-profiler”
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 Profiler loads about 182 tokens when it runs. Until then it costs about 28 tokens; SKILL.md has 48 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 48 words (~182 tokens).
“Run profiling tools and capture hotspots with evidence.”
