Critic

critic

A Claude Code plugin for multi-reviewer fiction critique. The plugin runs parallel reviews from Claude (as a subagent inside cowork), Codex (via the OpenAI Codex CLI), and Pi (via the Pi harness). It cross-reviews, synthesises into ranked issues with stable IDs, and saves to your vault for future reviews to build on.

The vault has to be an obsidian-storyline project. Scenes live in Scenes/, characters and locations in Codex/, worldbuilding in Research/. The critic reads scenes in act → chapter → sequence order, exactly as storyline's own "Export project" command does, and uses the rich frontmatter to scope reviews and pre-filter context.

Quickstart

# Build the server
cd critic/server
go build -o ../bin/critic .

# Load the plugin
claude --plugin-dir /path/to/critic

# Point critic at your storyline project (the folder containing Scenes/, Codex/, Research/)
/critic:settings vault_path /path/to/vault/MyNovel

# Configure Pi (optional)
/critic:settings pi_provider google
/critic:settings pi_model gemini-2.5-pro

The first review:

/critic:manuscript

Interactive. Pick which reviewers run, which Pi model, which steps. Then it runs straight through.

Documentation

• Goals. What the critic is for and what it deliberately isn't.
• Architecture. How the pieces fit together.
• Vault layout. What files live where and what critic reads or writes.
• Skills. Every /critic:* command in detail.
• Server. The Go MCP server: tools, vault layer, agent wrappers.
• Prompts. Every prompt template, who uses it, override rules.
• Workflows. Example sessions from a fresh project through a revision cycle.

Prerequisites

• Claude Code 1.0.33+
• Go 1.21+ to build the server
• obsidian-storyline plugin set up on an active project
• Codex CLI authenticated (codex login). Optional, disable via /critic:settings codex_enabled false.
• Pi CLI installed and authenticated. Optional, disable via /critic:settings pi_enabled false.

Claude itself runs as a Task subagent inside cowork. No external process, nothing to configure.
