What is the MRSF Document Review SkillProof Score?

8.8/10 — installs cleanly 4/5, triggers reliably 5/5, output vs. baseline 8/10, docs & honesty 5/5.

How do I install MRSF Document Review?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use MRSF Document Review with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

MRSF Document Review

Turns Markdown feedback into anchored, resolvable review comments (a real YAML sidecar) instead of a flat comment list.

Test report

Verdict: Works with setup
Score: 8.8/10
Tested: Jul 15, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · d566c10

Ran the real @mrsf/cli (same engine the MCP tools wrap) against a throwaway doc: produced a genuine validated YAML sidecar with UUIDs, severity/type tags, and fuzzy-reanchor metadata, versus a baseline flat-text review list - concretely more useful for multi-round or CI-driven review, but nothing works until the separate @mrsf/mcp server is installed and registered as an MCP server first.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

What MRSF Document Review does

Reviews Markdown documents by adding structured, line-anchored comments through the MRSF (Sidemark) MCP server, tagging each with type/severity and storing them in a .review.yaml sidecar that survives document edits via re-anchoring. Triggers when asked to review, comment on, or give feedback on a Markdown file; requires the separate @mrsf/mcp server to be installed and registered before the tools exist.

How to install MRSF Document Review

git clone https://github.com/wictorwilen/MRSF
mkdir -p ~/.claude/skills
cp -r MRSF/examples/mrsf-review ~/.claude/skills/mrsf-review
npm install -g @mrsf/mcp   # required MCP server, not bundled in the skill folder

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.

Commands — how to trigger MRSF Document Review

/mrsf-review Turns Markdown feedback into anchored, resolvable review comments (a real YAML sidecar) instead of a flat comment list.

It also activates on plain-language prompts like these:

Review this markdown doc and leave anchored comments I can resolve
Give feedback on this deployment doc with severity-tagged comments
Comment on this spec so the notes survive future edits to the file
