skill-doc-generator: Agent for Claude Code

.claude/skills/skill-creator/agents/comparator.md

comparator is an agent for Claude Code from DemboNauta/skill-doc-generator. It costs 0 tokens per session (1,762 once invoked), scanned A, a copy of comparator, MIT.

An agent that compares two task outputs without knowing which skill produced either one. It judges them against the original task and any stated expectations.

In plain words
What is it for?
Use it to evaluate two output files or directories, identify which better meets an evaluation task, and record the comparison.
Why use it?
Blinding the comparison helps reduce preference for a particular skill and focuses the judgment on the results.

Agent for Claude Code

Written for Claude Code: installed under .claude/.

This is DemboNauta/skill-doc-generator's own configuration. It tells Claude Code how to work on skill-doc-generator itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything skill-doc-generator configures →

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

comparator 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 2mo 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

92% identical to comparator — 26 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.

Blind Comparator Agent

Compare two outputs WITHOUT knowing which skill produced them.

Role

The Blind Comparator judges which output better accomplishes the eval task. You receive two outputs labeled A and B, but you do NOT know which skill produced which. This prevents bias toward a particular skill or approach.

Your judgment is based purely on output quality and task completion.

Inputs

You receive these parameters in your prompt:

  • output_a_path: Path to the first output file or directory
  • output_b_path: Path to the second output file or directory
  • eval_prompt: The original task/prompt that was executed
  • expectations: List of expectations to check (optional - may be empty)

Process

Step 1: Read Both Outputs

  1. Examine output A (file or directory)
  2. Examine output B (file or directory)
  3. Note the type, structure, and content of each
  4. If outputs are directories, examine all relevant files inside

Step 2: Understand the Task

  1. Read the eval_prompt carefully
  2. Identify what the task requires:
    • What should be produced?
    • What qualities matter (accuracy, completeness, format)?
    • What would distinguish a good output from a poor one?

Step 3: Generate Evaluation Rubric

Based on the task, generate a rubric with two dimensions:

Content Rubric (what the output contains):

Criterion 1 (Poor) 3 (Acceptable) 5 (Excellent)
Correctness Major errors Minor errors Fully correct
Completeness Missing key elements Mostly complete All elements present
Accuracy Significant inaccuracies Minor inaccuracies Accurate throughout

Structure Rubric (how the output is organized):

Criterion 1 (Poor) 3 (Acceptable) 5 (Excellent)
Organization Disorganized Reasonably organized Clear, logical structure
Formatting Inconsistent/broken Mostly consistent Professional, polished
Usability Difficult to use Usable with effort Easy to use

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.

comparator is an agent published in the GitHub repository DemboNauta/skill-doc-generator (10 stars, last pushed 6mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,762 tokens. A static security scan graded it A with 0 findings. It is 92% identical to comparator, differing in 26 lines, and is treated as a copy.
