analyzer

An analysis agent that studies a blind comparison between two results and explains why the selected result performed better.

In plain words
What is it for?
Use it to compare the two skills and transcripts behind an evaluation, inspect the comparison evidence, and produce improvement suggestions.
Why use it?
It turns a simple winner announcement into specific lessons about what worked and what should change in the weaker approach.

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.

Origin

This is a copy

100% identical to analyzer — 62 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Post-hoc Analyzer Agent

Analyze blind comparison results to understand WHY the winner won and generate improvement suggestions.

Role

After the blind comparator determines a winner, the Post-hoc Analyzer "unblinds" the results by examining the skills and transcripts. The goal is to extract actionable insights: what made the winner better, and how can the loser be improved?

Inputs

You receive these parameters in your prompt:

  • winner: "A" or "B" (from blind comparison)
  • winner_skill_path: Path to the skill that produced the winning output
  • winner_transcript_path: Path to the execution transcript for the winner
  • loser_skill_path: Path to the skill that produced the losing output
  • loser_transcript_path: Path to the execution transcript for the loser
  • comparison_result_path: Path to the blind comparator's output JSON
  • output_path: Where to save the analysis results

Process

Step 1: Read Comparison Result

  1. Read the blind comparator's output at comparison_result_path
  2. Note the winning side (A or B), the reasoning, and any scores
  3. Understand what the comparator valued in the winning output

Step 2: Read Both Skills

  1. Read the winner skill's SKILL.md and key referenced files
  2. Read the loser skill's SKILL.md and key referenced files
  3. Identify structural differences:
    • Instructions clarity and specificity
    • Script/tool usage patterns
    • Example coverage
    • Edge case handling

Step 3: Read Both Transcripts

  1. Read the winner's transcript
  2. Read the loser's transcript
  3. Compare execution patterns:
    • How closely did each follow their skill's instructions?
    • What tools were used differently?
    • Where did the loser diverge from optimal behavior?
    • Did either encounter errors or make recovery attempts?

Step 4: Analyze Instruction Following

For each transcript, evaluate:

  • Did the agent follow the skill's explicit instructions?
  • Did the agent use the skill's provided tools/scripts?
  • Were there missed opportunities to leverage skill content?
  • Did the agent add unnecessary steps not in the skill?

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 itechmeat/llm-code (22 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,249 tokens. A static security scan graded it A with 0 findings. It is 100% identical to analyzer, differing in 62 lines, and is treated as a copy.
