The Agent Skills Directory

[COMMAND_EXECUTION]: Executes shell commands to run load tests (k6, ab), web audits (lighthouse), and network timing measurements (curl).
[COMMAND_EXECUTION]: Invokes language-specific profiling tools including Node.js heap snapshots/CPU profiles, Python's cProfile, and Go's benchmark/pprof tools.
[EXTERNAL_DOWNLOADS]: Utilizes npx to execute well-known bundle analysis and performance tools such as webpack-bundle-analyzer, vite, and bundlephobia.
[PROMPT_INJECTION]: Contains an indirect prompt injection surface (Category 8) where the agent processes data from external URLs.
Ingestion points: Target URLs provided to lighthouse, curl, ab, and k6 commands.
Boundary markers: Absent; the skill does not wrap tool outputs in delimiters or provide instructions to ignore embedded content in reports.
Capability inventory: Executes subprocesses for various CLI tools, writes files (results.json, report), and runs local scripts (app.js, app.py, script.js).
Sanitization: No validation or sanitization of the remote content fetched by these tools before it is presented to the agent.
[COMMAND_EXECUTION]: Employs dynamic script generation (Category 10) by using shell heredocs to create and execute k6 scripts inline.
