compare

A command for comparing two software projects. It examines their structure, code quality, tests, documentation, unfinished work, and practical value.

In plain words
What is it for?
Reviewing two codebases side by side, scoring their strengths and weaknesses, and deciding which approach to use.
Why use it?
It gives a structured comparison when it is difficult to judge which project is better or what each project should improve.

Getting it into your agent

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.

Made for: Claude Code.

Per session 5 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 360 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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 yesterday.

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

Karen Comparative Analysis

Compare $1 vs $2 with brutal honesty.

Scan Both Projects

For each project:

  • File count and structure
  • Code quality patterns
  • Test coverage
  • Documentation
  • TODO count

Scoring Comparison

Score each dimension (0-20) for both projects:

Project 1: $1

🎭 Bullshit Factor: X/20 ⚙️ Actually Works: X/20 💎 Code Quality: X/20 ✅ Completion: X/20 🎯 Practical Value: X/20 Total: X/100

Head-to-Head Analysis

Winner: [Project name] by X points

Why:

  • [Key differentiator 1 with file:line refs]
  • [Key differentiator 2 with file:line refs]
  • [Key differentiator 3 with file:line refs]

What the loser should steal:

  • [Feature/pattern from winner]
  • [Approach from winner]

What both should fix:

  • [Common issue]
  • [Common anti-pattern]

Recommendation

  • Use $1 if: [Specific scenario]
  • Use $2 if: [Specific scenario]
  • Use neither if: Better alternatives exist (list them)
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 pr-pm/prpm (120 stars, last pushed 2mo ago), licensed MIT. It adds 5 tokens to every session and 360 once invoked, about $0.0000 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 2026-08-30.
