profile

profile is a command for coding agents from juanmhidalgo/claude-plugins. It costs 40 tokens per session (516 once invoked), scanned A, original, MIT.

A focused performance-measurement command for a specific function, API endpoint, or component. It uses timing and profiling data to show where execution time or memory is being spent.

In plain words
What is it for?
Use it to measure runtime, find slow functions or database queries, inspect call counts, and guide targeted optimizations.
Why use it?
It replaces guesses about what is slow with measurements that identify the actual bottleneck.

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 A, and why

profile scanned grade A with 0 findings 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 yesterday.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Context

  • Branch: !git branch --show-current

Focused Profiling

Target: $ARGUMENTS

Step 1: Understand the Code

Read the target function/endpoint. Understand what it does, what it calls, and what data flows through it.

Step 2: Identify Measurement Approach

Based on the language and context:

Python:

python -m cProfile -s cumulative script.py
python -m timeit -s "setup" "expression"

Node.js:

console.time('operation');
// ... code ...
console.timeEnd('operation');

Database queries:

  • Enable query logging to see actual SQL and timing
  • Check for N+1 patterns in the query log
  • Look for missing indexes on WHERE/JOIN columns

Step 3: Profile

Run the profiling tool and collect baseline numbers. Record:

  • Total execution time
  • Hot spots (functions consuming the most time)
  • Call counts (functions called most frequently)
  • Memory allocation (if relevant)

Step 4: Analyze & Recommend

For each hot spot:

  1. Is it doing unnecessary work? (redundant computation, fetching unused data)
  2. Is it doing work at the wrong time? (could be cached, deferred, or parallelized)
  3. Is it using an inefficient algorithm? (O(n²) when O(n) is possible)

Provide specific fix recommendations with expected improvement.

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.

profile is a command published in the GitHub repository juanmhidalgo/claude-plugins (8 stars, last pushed 10d ago), licensed MIT. It adds 40 tokens to every session and 516 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
