fix(hooks): the by-name duplicate arm confirms its grep hits against the real extractor (#4227)
#4222 fixed one end of this defect — the extractors that decide what a payload
DEFINES now blank comment and string spans before any line matcher runs. This
is the other end: `scribe_local_dups`, which decides which OTHER files already
define that name, and which was still a plain `git grep`.

A grep sees lines, not spans, so the sentence

    class with only modifier rules is a deletion that went half-way.

— real prose from a module docstring in this repo — matched the arm's pattern
for `name=with`. Writing a genuine `change`, `beside` or `wrapped` would be
told it already existed, and pointed at a docstring.

EVERY HIT IS NOW CONFIRMED by running `scribe_defs` over the candidate file and
keeping only names it actually reports. That is the only check that cannot
disagree with the other end of the pipe, which is the whole point.

MEASURED, NOT ASSUMED — both numbers the task reasoned from turned out wrong.

  - WHAT IT REMOVES, across 141 payload files of this repo: 15 of 210 report
    lines. Every one a string literal, a comment, a TypeScript `import { type
    Foo }`, or Vue's `const emit = defineEmits()` boilerplate. No real
    definition was lost. Where a name had both — `create_note` — the phantom
    in a test's `shape_form("async def create_note(...)")` argument dropped out
    and the definition in services/notes.py stayed. `with` went from four files
    to none, which is the correct answer: nothing here defines it, and it is a
    keyword in several of these languages.

  - WHAT IT COSTS: mean 193ms -> 222ms, worst 569ms -> 572ms. The task feared
    "over a second added to a PreToolUse hook" from 48 confirmations. It is
    about 15%, because the arm was already dominated by its twelve `git grep`
    calls, and because confirmation runs once per DISTINCT candidate file
    rather than once per (name, file) pair. A deliberately pathological payload
    — nine names that are ordinary English words — reaches 28 distinct files
    and 947KB; `scribe_defs` runs at ~33ms per 250KB.

THE CANDIDATE CAP IS RAISED FROM FOUR TO TWELVE, and that is load-bearing.
Confirmation REMOVES hits, so capping before it runs lets phantom matches crowd
a real definition out of the window — hits dropped before anyone looked at
them, which is #4042's bug in a new place. The display cap stays at four and
now applies to CONFIRMED hits, which is where a cap belongs. #4042's own `||
true` inside the substitution is untouched, and its regression case still
passes.

The task's own advice not to fix this by tightening the grep pattern is
followed and written down: requiring `(` or `{` or `:` after the name rejects
`class with only…` and also `class Foo extends Bar {`, `class Foo : Base()` and
`type Foo struct {`. This arm exists because it works with no server, no index
and no binding (#2280, #2682), which makes a miss here invisible — a visible
false positive is the better failure.

Guards: tests/test_hook_duplicate_confirmation.py, against real git repos
because what is pinned is the interaction between `git grep`, `head` and the
extractor. Seven of the eight fail against the previous implementation; the
eighth is #4042's regression case, whose job is to keep passing.

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.
