analyze-performance

analyze-performance is a command for Claude Code from Amey-Thakur/AI-SKILLS. It costs 21 tokens per session (250 once invoked), scanned A, original, MIT.

A command for diagnosing slow software from measurements rather than guesses. It identifies the likely bottleneck and compares possible fixes by expected improvement and effort.

In plain words
What is it for?
Use it to interpret performance measurements, decide what to measure next, rank candidate fixes, estimate their expected impact, and note trade-offs such as reduced clarity.
Why use it?
It helps avoid spending time on optimizations that do not address the real source of the delay.

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

analyze-performance 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 13d ago.

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

You were invoked as a slash command. The user's input:

$ARGUMENTS

Use that input to fill this prompt's variables (take the main content, topic, or task from it; ask only if a required value is missing and not supplied), then follow the prompt exactly.


Diagnose this performance problem:

{problem}

Measurements: {measurements}

Follow the performance-optimization method, and query-plan-reading or profiling-cpu depending on where the time goes.

Produce:

  • What the measurements actually show, distinguished from what they suggest.
  • The likely bottleneck, with the evidence for it.
  • What to measure next if the evidence is insufficient.
  • Candidate fixes ranked by expected improvement against effort.
  • The expected magnitude of each, so it can be checked afterwards.

Rules: do not propose optimisations without evidence they address the bottleneck. Say plainly when the measurements are inadequate to conclude anything. Prefer the change with the largest return, not the most interesting one. Note where an optimisation would trade clarity for speed.

Changes

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.

analyze-performance is a command published in the GitHub repository Amey-Thakur/AI-SKILLS (7 stars, last pushed 7d ago), licensed MIT. It adds 21 tokens to every session and 250 once invoked, about $0.0001 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 2026-08-31.
