Scribe plugin for Claude Code

Turns a self-hosted Scribe instance into a first-class Claude Code extension:

• MCP tools over your notes, tasks, projects, milestones, systems, and rulebook (the scribe server).
• Session-start push channel — a SessionStart hook injects your always-on rules + active-project context so Scribe surfaces without being asked.
• Prior-art recall on writes — a PreToolUse hook on Write/Edit checks the file about to be written against your recorded snippets (what's kept at that path, and what resembles the code) and offers them before the helper is rewritten. Titles only, never blocks the edit.
• Universal process-skills — using-scribe, writing-plans, systematic-debugging, verification, brainstorming, reusing-code (record and recall reusable code as snippets). Replaces superpowers.
• Your Scribe Processes as skills — saved Processes are synced into local ~/.claude/skills/scribe-proc-* stubs that auto-surface by relevance; the stub fetches the live procedure via get_process. Refreshed each session and on demand with /scribe:sync.

It is designed so you can uninstall superpowers and disable auto-memory and depend on neither.

Install

The plugin ships inside the Scribe app repo, so the marketplace is that repo — you always get the plugin version that matches your Scribe instance.

/plugin marketplace add https://git.fabledsword.com/bvandeusen/FabledScribe.git
/plugin install scribe@scribe-plugin

On install you'll be asked for:

Setting	What
Scribe base URL	e.g. https://scribe.example.com (no trailing slash)
Scribe API key	an fmcp_ key from Settings → API Keys (stored in your OS keychain)
Active project id	optional — numeric project id to scope the session-start context

What gets wired

• plugin.json mcpServers → the scribe MCP server at <base URL>/mcp (Bearer auth).
• hooks/hooks.json → SessionStart hook (hooks/scribe_session_context.sh), fail-open: if Scribe is unreachable it injects nothing and never blocks the session.
• hooks/hooks.json → PreToolUse hook on Write|Edit (hooks/scribe_prior_art.sh) → GET /api/plugin/prior-art. Returns additionalContext with no permission decision, so it can inform the write but never stop it; silent when nothing is recorded, which is most of the time. Two framings: a REUSE menu (similar/nearby records), and a SYNC nudge when a snippet records the exact file being edited — "updating the record is part of the edit" — each with its own once-per-session dedup. A third, ledger-fed line names a duplicate family (no canon) or a canon recorded elsewhere for the names being written (its own dedup channel, exclude_derive). Toggle in Settings → Knowledge auto-inject.
• hooks/hooks.json → PostToolUse hook on Bash (hooks/scribe_after_write.sh): code written through sed/heredocs/scripts never reaches the PreToolUse hook, so this one diffs the working tree after every Bash call (per-session path+blob snapshot; one git status when nothing changed) and runs the same arms on the definitions just written, through the same endpoint and the same dedup channels. additionalContext only; silent on any failure. The extractor, the prose/data skip list and the local by-name duplicate arm are shared in hooks/scribe_defs.sh.
• skills/ → the universal process-skills, surfaced by description match.
• hooks/scribe_sync_processes.sh (a 2nd SessionStart hook) + the /scribe:sync command → generate ~/.claude/skills/scribe-proc-* stubs from your Scribe Processes (via GET /api/plugin/processes); also fail-open, and pruned to match what exists in Scribe.

Notes

• Set a version bump in .claude-plugin/plugin.json per release so clients pick up changes.
• The session-start, auto-inject and prior-art hooks need only a read-scoped key; the MCP tools need write scope to create/update. Every hook is a GET for that reason — a read key cannot POST.
