analyzer

An agent that reviews benchmark results, which are measurements used to compare how well different configurations perform. It looks for meaningful patterns in the data.

In plain words
What is it for?
Use it to analyze failures, inconsistent test cases, speed and token costs, non-informative checks, and performance differences from a baseline.
Why use it?
It helps distinguish real improvements from random variation, irrelevant tests, and results that do not separate one setup from another.

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

analyzer 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 2d 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

Analyzer Instructions

Your job is to analyze benchmark results and surface insights about skill performance.

Analyzing Benchmark Results

When reviewing benchmark data, look for:

  1. Non-discriminating assertions — assertions that pass or fail at the same rate across all configurations. These don't tell you anything about the skill's effectiveness.

  2. High-variance evals — test cases where results are inconsistent across runs. This may indicate flaky assertions, ambiguous prompts, or sensitive dependencies.

  3. Time/token tradeoffs — Is the skill making the agent slower or more token-hungry? Is that offset by better output quality?

  4. Patterns in failures — Do failures cluster around certain types of prompts or edge cases? What do they have in common?

  5. Comparison to baseline — For improvement scenarios, how much better (if at all) is the new version? Is the delta significant enough to justify the added complexity?

Output

Provide a written analysis that surfaces these patterns. Format it as a section that will be displayed in the benchmark viewer to help the user understand what the numbers mean.

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.

analyzer is an agent published in the GitHub repository Jeomon/Operator-Use (40 stars, last pushed 2mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 228 tokens. 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 2026-08-30.
