What is Critical Compass?
Critical Compass is a critical-thinking toolbox for people who need written work to hold up under scrutiny. Paste in a grant narrative, advocacy draft, public statement, report, or article, and it helps spot weak evidence, hidden assumptions, framing gaps, missing voices, and claims to verify before you publish or submit. It can be used through the plugin, MCP/extension, or skill files below.

What Is Critical Compass?
Critical Compass is a local critical-thinking assistant for pressure-testing written work before it is published, submitted, shared, or used to make a decision. It is designed for drafts that need to hold up under scrutiny: grant narratives, advocacy writing, public statements, reports, articles, policy arguments, and other high-stakes text.
It does not just proofread. Critical Compass looks for the reasoning underneath the writing: the central claims, evidence gaps, assumptions, possible bias patterns, missing stakeholder perspectives, framing risks, audience fit, and claims that need verification. It helps answer a practical question: if someone smart and skeptical read this, where would it hold up and where would it break?
For non-technical users, it works like a structured review partner. For technical users, it exposes a local audit workflow with tools for quick scans, full audits, claim stress tests, reasoning-framework lookup, saved audit results, report validation, report generation, and advanced multi-perspective review.
How It's Built
Critical Compass is distributed as a local MCP/extension, a Claude Cowork or Claude Code plugin, and a prompt-only skill. The MCP exposes tools for onboarding, routing, quick scans, full audits, advanced audits, claim stress tests, fact-check planning, knowledge-base lookup, saved results, pattern tracking, report validation, and report generation.
Under the hood, it combines structured audit workflows with a critical-thinking knowledge base. That knowledge base includes biases, fallacies, reasoning frameworks, thinking lenses, methodology checks, reasoning flows, and reusable audit scaffolds. The workflow layer turns those resources into repeatable review steps instead of asking the model to invent an audit process from scratch.
The system is local-first and scaffold-first by default. It can help identify what should be verified, but it does not require Google, Brave, provider keys, or live retrieval for its core audit workflows. Advanced audit paths add role and persona scaffolds for multi-perspective review while keeping the user in control of the final judgment.
What's Inside
A compact map of the major MCP surfaces — what they do and how to ask for them.
get_started-
First-session onboarding: clarifies goal, intended audience, and audit depth, then routes to the right tool.
Say: “I'm new - help me get started with Critical Compass.”
critical_compass_overview-
Friendly map of workflows, routing rules, case examples, and starter prompts.
Say: “Give me an overview of Critical Compass.”
quick_scan-
Lightweight gut-check with a Critical Integrity Snapshot, top risks, key tension, and one next action.
Say: “Quick-scan this text before I decide whether it needs a full audit.”
audit_text-
Full audit for assumptions, bias patterns, evidence gaps, argument structure, check-worthy claims, alternative frames, and audience fit.
Say: “Run a full Critical Compass audit on this text.”
advanced_audit-
High-stakes multi-perspective review with analyst roles, tension mapping, debate, dissent, and synthesis.
Say: “Run an advanced audit on this draft.”
lookup_bias / get_framework / search_knowledge_base-
Knowledge-base lookup tools for verified bias definitions, thinking lenses, frameworks, and reasoning flows.
Say: “Search Critical Compass for this concept before citing it.”
save_audit_result / compare_audit_results-
Saved-result tools for longitudinal review, score comparison, bias changes, and framing-drift scaffolding.
Say: “Save this audit result, then compare it to the revised version.”
validate_report_payload-
Read-only dry run for report schema, field constraints, renderer diagnostics, and preflight blockers before rendering.
Say: “Validate this report payload before generating the PDF.”
generate_audit_report-
Turns completed audit data into a stakeholder-ready PDF, Markdown file, manifest, and local viewer.
Say: “Generate a PDF report from this completed audit.”
How I Use It
I use Critical Compass when I want to slow down before trusting, publishing, citing, sharing, or acting on a piece of writing. It is especially useful for articles, research papers, drafts, or other writing someone sends me when I need to know whether the evidence, assumptions, framing, and audience fit are actually strong enough.
For quick reads, I use a quick scan for the plain-language read, the Before Using This Text caution, and the one action worth taking next. For important drafts, I use a full audit so the tool can map claims, surface evidence gaps, flag reasoning traps, and suggest what would make the argument more credible. For high-stakes or politically sensitive work, I use advanced audit mode because multiple perspectives are better than one confident pass.
I use it as a decision-support tool, not as an automatic judge. Claude is strong at conversational synthesis and stakeholder-sensitive framing; Codex is useful when I want the audit turned into structured artifacts, reports, or implementation-ready follow-up work. In both cases, Critical Compass gives the model a disciplined review path instead of leaving the critique up to vibes.

The example shows how Critical Compass turns a draft into a reader-ready pressure test: plain-language risk summary, evidence gaps, missing voices, assumptions, reasoning traps, and concrete next steps.
- Flags claims that need stronger evidence before publication.
- Names missing stakeholder perspectives and framing limits.
- Separates check-worthy claims from claims that are actually false.
- Gives revision prompts that help strengthen the text without flattening its purpose.

Frequently Asked Questions
Quick answers about what Critical Compass does, how the files differ, and what to expect during install.
What does Critical Compass actually do?
Critical Compass is a reasoning layer, not a spell-checker. It asks the hard questions your reader may ask about evidence quality, claim strength, hidden assumptions, framing bias, missing voices, and language that could overstate your case.
Who is it for?
It is for nonprofits, grant writers, advocacy communicators, policy teams, public affairs staff, and anyone who submits, publishes, or presents written work that needs to hold up under scrutiny.
What is an MCP connector or extension?
MCP means Model Context Protocol. In this context, Claude may call the local tool connection an MCP, connector, or extension. Critical Compass's extension is the MCP connector: it gives Claude tools plus bundled indexes and resources for pressure-testing text. Learn more about MCPs.
What is the difference between the plugin, extension, and skill?
Plugin zip: the Claude Cowork or Claude Code bundle. It includes the MCP/extension, skill, and predefined agents. Extension file: the Claude Desktop MCP connector, which gives Claude tools and bundled resources so it can do more with fewer tokens. Skill: the prompt-only alternative Claude can read without the MCP, though it may use more context. You can install more than one.
Does this work with Codex?
Yes. Critical Compass can work with Codex because Codex can use local MCPs, skills, and plugins. This page does not yet provide a one-click Codex install path; technical Codex users can use the source zip or the AI-assisted install prompt in Advanced.
Is Critical Compass safe to install?
Downloading anything from the internet carries real risk: malicious code, data collection, hidden scripts. Critical Compass is designed to reduce that surface area: it runs locally on your machine, requires no API key, bundles its own files, and does no background scanning. That said, no third-party tool is zero risk. Before installing, you're encouraged to review the source files or have a trusted technical contact look them over. Claude's warning is the standard prompt it shows for all locally shared third-party plugins, not a flag specific to this tool. Learn more about MCP risks.
Do I need a GitHub account to download?
No. The download buttons go directly to the files. GitHub is only where the files are hosted.
