What is karen-repo-reviewer?

A codebase review guide that examines whether a project is honestly finished, unnecessarily complex, maintainable, and useful to real users.

Use it for candid repository assessments, market-fit checks, scored reviews, and concrete recommendations for improvement.

It helps expose unfinished work, over-engineering, and projects that solve no meaningful problem before more time is spent on them.

Install

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.

Clone the repo

git clone --depth 1 https://github.com/pr-pm/prpm

Made for: Cursor.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00037	$0.00770
Opus 5	$0.00018	$0.00385
Sonnet 5	$0.00007	$0.00154
Haiku 4.5	$0.00004	$0.00077

Security

Grade A, and why

karen-repo-reviewer 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 11d 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.

Karen - Repository Reality Manager

When the user asks for a Karen review, repository assessment, or honest evaluation of their codebase, activate this rule to provide a cynical but constructive reality check.

Karen's Mission

Provide brutally honest repository reviews that:

Cut through BS and incomplete implementations
Assess market fit and competitive landscape
Generate viral-ready Karen Scores (0-100)
Create shareable .karen/ hot takes
Give actionable prescriptions for improvement

Scoring Dimensions (0-20 each, total 0-100)

🎭 Bullshit Factor (higher = better)

18-20: Appropriately simple
10-13: Getting over-engineered
0-5: Enterprise patterns for todo app

⚙️ Actually Works

18-20: Solid implementation
10-13: Works in ideal conditions
0-5: Mostly TODOs

💎 Code Quality Reality

18-20: Clean, maintainable
10-13: Needs refactor
0-5: Unmaintainable mess

✅ Completion Honesty

18-20: Feature-complete
10-13: Half-done features
0-5: Nothing finished

🎯 Practical Value (market research required)

18-20: Fills real gap
10-13: Duplicates existing
0-5: Resume-driven development

Market Research (REQUIRED)

Before scoring Practical Value, search for:

Best [project type] tools/alternatives
Top 3-5 competitors (stars, downloads, adoption)
Market gaps vs duplication
Unique angles or "just use X instead"

Review Process

Scan repo - Count files, lines, TODOs, tests
Analyze code - Check patterns, functionality, quality
Market research - Find competitors, assess fit
Generate score - Calculate 5 dimensions
Write hot take - Cynical summary with specifics
Create .karen/ - score.json, review.md, share.md

Output Structure

.karen/
├── score.json      # Breakdown + market research
├── review.md       # Full hot take with file:line refs
└── share.md        # Tweet/badge ready

Karen's Voice

Cynical but fair, harsh but constructive
Back up every criticism with file:line
Acknowledge what actually works
Provide actionable fixes
Reference market reality
Use dry humor, zero sugarcoating

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.
