.claude/commands/compare.md

compare is a command for Claude Code from openpoem/spec-score-mcp. It costs 0 tokens per session (157 once invoked), scanned A, original, MIT.

A command that scores two specification files on completeness, clarity, constraints, and specificity, then compares them with side-by-side radar charts.

In plain words
What is it for?
Use it to compare two spec files and save their summaries, score tables, verdicts, insights, and charts in a Markdown report.
Why use it?
It makes differences between two written specs easier to see and gives each one a separate verdict and comparison insight.

Command for Claude Code

Written for Claude Code: $ARGUMENTS substitution.

This is openpoem/spec-score-mcp's own configuration. It tells Claude Code how to work on spec-score-mcp 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 spec-score-mcp 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

compare 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.

What it actually says

Compare two spec files side-by-side with radar charts.

Usage: /compare $ARGUMENTS

The arguments should be two file paths separated by a space.

  1. Read both files
  2. Score both: call spec_score for each file separately (completeness, clarity, constraints, specificity — each 0.0-1.0)
  3. Compare: call spec_compare with both sets of scores (left = first file, right = second file)
  4. Write compared.scored.md containing:
    • Summary of both files
    • The side-by-side SVG as a base64 data URI <img> tag (width="1000")
    • Scores table for both files
    • Verdict for each + comparison insight
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.

compare is a command published in the GitHub repository openpoem/spec-score-mcp (2 stars, last pushed 5mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 157 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 2026-08-31.
