Milestone 419 step 4. Five of the milestone's seven misses were the same move: acting on the thing in hand without reading the contract around it. Lesson #4207 says so in words, and was written by its author hours before a structurally identical mistake, having been surfaced twice in the turns between. Text delivered at the moment of acting is too weak a carrier for a reflex that has to change what the act IS. This looks it up instead. Rule 33 one scope down: its checks are between layers, and the same question exists between a definition and its callers. THREE KINDS OF EXPOSED NAME, because a contract breaks three ways that look nothing alike in source — the defined symbol (a rename or removal), its parameter names (arity), and the quoted keys of its dict literals (the shape of what it returns). THE THIRD IS THE ONE A SIGNATURE-WATCHER MISSES, and it is in because of the miss that produced this step. Two commits ago `get_writepath_config` gained one dict key; three arms read that dict inside a fail-open `except`, every one silently became a no-op, and ten tests went red with nothing pointing at the cause. No signature changed. Run against that exact edit, the check now names tests/helpers.py — the actual root cause — among six files, before the write. TWO GATES, AND THE SECOND IS WHAT MAKES IT USABLE. A change to the exposed set is necessary but not sufficient: a definition nothing else references has no contract to break, so the readers lookup runs second and an empty result ends it silently. Body-only edits say nothing, a subject is named once per session, and the ledger lives in the swept directory under the `.ids` convention, so the existing compaction-clear guards cover it — checked against test_session_ledger_clear's own parsers rather than assumed. LOCAL AND SERVERLESS, like the duplicate-name arm beside it. It needs the working tree and nothing else; the server has no checkout, so this is the only place the question can be asked. It is a NUDGE: scribe_prior_art.sh still returns no permissionDecision, which is the operator's recorded decision that a recall aid may not stand in the way of a write. A test asserts that here as well as in test_write_path_trigger.py, because this is the arm most likely to tempt someone into making it a gate — it reports something that may already be broken. The `sym` half delegates to `scribe_defs` rather than repeating its patterns: those cover nine languages and have been corrected several times, and a second copy would inherit today's version and quietly stop agreeing with it (#3497). Verified by lifting the test file's own helpers and driving all 19 cases against the real shell over a fixture git repo. Two of my own errors were caught that way and are fixed: the fixtures were arriving as single lines because Python `repr` inside bash single quotes leaves `\n` as two characters (the extractor is line-oriented, so the tests would have gone green against input no editor can produce), and the no-readers case put its subject in a file that was not the excluded one, so it had a reader and tested the opposite of its name.

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
scribeserver). - Session-start push channel — a
SessionStarthook 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
PreToolUsehook 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 viaget_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.jsonmcpServers→ thescribeMCP 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 onWrite|Edit(hooks/scribe_prior_art.sh) →GET /api/plugin/prior-art. ReturnsadditionalContextwith 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 onBash(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; onegit statuswhen nothing changed) and runs the same arms on the definitions just written, through the same endpoint and the same dedup channels.additionalContextonly; 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 inhooks/scribe_defs.sh.hooks/hooks.json→ Stop hook (hooks/scribe_report_check.sh): when the turn closed a Scribe task (update_task/create_taskwith 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 toGET /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 categoryplugin, actionreport_check.skills/→ the universal process-skills, surfaced by description match.hooks/scribe_sync_processes.sh(a 2nd SessionStart hook) + the/scribe:synccommand → generate~/.claude/skills/scribe-proc-*stubs from your Scribe Processes (viaGET /api/plugin/processes); also fail-open, and pruned to match what exists in Scribe.
Notes
- Do not hand-edit
versionin.claude-plugin/plugin.json. It is minted from the clock — runpython3 scripts/mint_plugin_version.py(ormake mint-plugin, wheremakeis installed) after changing anything underplugin/, 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.
