Why it helps

Knotr gives software teams one context layer for how you review code, document systems, and enforce writing standards. Connect your IDE once over MCP and reuse the same profile, knowledge, and skills across tools, without re-uploading docs or rewriting prompts.

Review Rails code, optimize Postgres queries, and catch security issues from your IDE
Keep coding standards, architecture notes, and performance context searchable in one place
Enforce clear PR descriptions, API docs, and runbook prose from any connected tool

Context your AI can search

Editable starter notes in "Engineering Context" so answers reflect how your team works:

Coding Standards & Review Expectations
Architecture & System Overview
Database & Performance Notes

Ideas to supplement later

Architecture Decision Records (ADRs) for recent major choices
API contracts / OpenAPI specs for services you integrate with
On-call runbook links and escalation contacts
Security/compliance requirements specific to your org
CI/CD pipeline overview and deploy windows

Writing that stays on-brand

"Engineering Writing Standards". PR descriptions, API docs, and runbook prose for engineering teams.

On eligible accounts, lint drafts from any connected AI tool with MCP check_style so PR descriptions, docs, and updates match your standards. Free accounts include one bootstrap style guide.

Prefer concrete metrics over vague quantifiers like "many" or "significantly"
Use active voice for procedural steps in runbooks and incident notes
State assumptions explicitly; avoid hedging with "we believe" or "it appears"

Grow your library when you are ready

After signup you can connect these skill-only plugin repos (no MCP or OAuth required). Knotr syncs the marketplace so you can browse and import individual skills later. Imports are not automatic, so you stay within your plan's skill limit.
