feat(plugin): a directory says which project it belongs to, git repo or not (#4085)
All six hooks scoped their requests one way: `git remote get-url origin`,
resolved server-side through the repo bindings. That key does not exist
outside a git repo, so a session in a plain directory was unscoped in every
hook at once — no project context, no prior-art scoping, no project rules —
and silently, because a missing remote is indistinguishable from a remote
nobody bound.

A `.scribe` file is the second key, read by the shared scribe_scope_query so a
directory scopes the same way everywhere:

    {"instance": "https://scribe.example.com", "project_id": 2, "project": "…"}

`instance` is why the file is not just a number: an id is a different project
on every Scribe, so a marker that travels — a copied directory, a shared
machine, a repo someone else clones — would otherwise scope the session to the
wrong project without a word. Compared host-only, and a mismatch drops the id:
no project beats the wrong project. A bare integer is accepted too, since it
is what a person writes by hand. The marker beats a git remote — someone put
the file there on purpose — which is also how a directory overrides its
binding.

Two things it found on the way:

  * An explicit project_id that did not resolve rendered NO message at all —
    the branch hung off `if project_id` as an `elif`, so a caller holding a
    pointer it believed in got a context that silently omitted the project it
    had asked for. Now reported.
  * The refusal reason was a global set inside a function every caller reads
    through `$( )`. The assignment died with the subshell, leaving the caller
    to read an unset variable under `set -u` — which aborts the hook and costs
    the whole session's SessionStart context, to fetch a warning about a file.
    It comes back through stdout with the id instead, and a test pins it.

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 the active project's live state (from the server) and this adapter's short Claude Code guidance, so Scribe surfaces without being asked. Rules are never preloaded; they arrive by retrieval when your work matches one.
  • 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.
  • The shared Scribe skills — client-neutral Agent Skills, the same files any client's package would ship: using-scribe, writing-plans, reporting-back (reply to the operator in a shape that says where the work stands), 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 depend on Scribe instead of auto-memory — leave auto-memory at its default; Scribe replaces its job by holding the one copy, not by switching it off.

How the pieces divide the work (decision #4027): the Scribe server orients every MCP client and serves live state; the skills in skills/ state every reflex in full and name no client; this plugin is the Claude Code adapter — hooks that deliver at the right moment, /scribe:sync, and the few things only Claude Code needs said (hooks/scribe_static_context.md). Packaging Scribe for another client: see PACKAGING.md.

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). Fail-open but not fail-silent: a configured instance that does not answer in time is said, once per outage ("Scribe did not answer … this write went UNCHECKED"), so a session can tell "checked, nothing there" from "never checked"; an answer clears the marker. The local by-name arm needs no server and always runs. 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; never blocks, and shares the pre-write hook's once-per-outage "did not answer" line (8 s budget here — it runs after the tool, so it gates nothing). The extractor, the prose/data skip list, the local by-name duplicate arm and the outage line are shared in hooks/scribe_defs.sh.
  • hooks/hooks.json → Stop hook (hooks/scribe_report_check.sh): when the turn closed a Scribe task (update_task/create_task with status done), checks the reply that ends it for the completion sections — where the work sits, what needs you, what comes next — and reports the outcome to GET /api/plugin/report-check. If sections are missing it blocks once with the reason the server returns, and records how the rewrite came out; it never blocks twice, and never blocks when the instance did not record the check (unconfigured or unreachable). Outcomes land in the admin logs under category plugin, action report_check.
  • 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

  • Do not hand-edit version in .claude-plugin/plugin.json. It is minted from the clock — run python3 scripts/mint_plugin_version.py (or make mint-plugin, where make is installed) after changing anything under plugin/, and commit the result. The installer decides whether to refresh the cache it executes from by comparing that string, so content that ships without a new version reaches the repo and stops there (#2209). CI fails the lane if you forget.
  • 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.
