-# Scribe plugin — Stop hook: a reply that closes a task carries the completion
-# sections (milestone 409 step 5).
-#
-# Everything else the plugin does happens BEFORE the agent writes: context,
-# retrieval, the reporting-back skill. This is the one moment the finished
-# reply exists, so it is both the last chance to fix a report the operator
-# cannot read and the only place adherence to the shape can be measured.
-#
-# DETERMINISTIC, NO MODEL CALL. Three questions, cheapest first:
-#
-#   1. Did this turn close a Scribe task? An `update_task` / `create_task` tool
-#      call with status "done" since the turn's prompt, whose result was not an
-#      error. Most turns stop here, silently.
-#   2. Does the reply that ends the turn have the completion sections? Loosely:
-#      where the work sits (a record named by id and title, or step N of M),
-#      what needs the operator, and what comes next. Matched on the words that
-#      carry the meaning rather than exact headings, so the skill's wording can
-#      change without breaking this.
-#   3. If sections are missing, block once with a reason naming them. The agent
-#      rewrites; the rewrite is checked and recorded, and never blocked again.
-#
-# MEASURED FROM THE FIRST CALL. Each checked reply is reported to the instance
-# (`/api/plugin/report-check`): passed, blocked, and after a rewrite either
-# passed_after_rewrite or missing_after_rewrite. Turns that closed no task are
-# not reported — they would cost a request on every turn and add nothing to
-# the rate step 6 reads (blocked among checked replies).
-#
-# IT BLOCKS ONLY WHEN THE BLOCK IS RECORDED, AND ONLY IN THE SERVER'S WORDS.
-# The report goes out first; the instance answers a recorded `blocked` with
-# the reason to send the agent back with, and the hook blocks only on that
-# reason. An unconfigured or unreachable instance therefore never stops a
-# session, every intervention is one the numbers can see, and the guidance
-# text lives on the server (plugin/PACKAGING.md: hooks carry timing and
-# transport).
-#
-# THE TRANSCRIPT FORMAT IS OBSERVED, NOT DOCUMENTED. Claude Code documents
-# `transcript_path` and `stop_hook_active` for Stop, not the JSONL inside. As
-# read from real transcripts (2026-09-14): one content block per line;
-# `type: "assistant"` lines carry `message.content[]` blocks of `text` /
-# `tool_use` ({id, name, input}); tool results arrive as `type: "user"` lines
-# whose content is a `tool_result` array ({tool_use_id, is_error}); a turn's
-# prompt — typed, or a background-task notification — is a `user` line whose
-# content is a plain string and which is not `isMeta`. Anything that does not
-# parse that way makes the hook stay out of the way rather than guess.
-#
-# Config (same as the other hooks):
-#   CLAUDE_PLUGIN_OPTION_API_ENDPOINT  base URL, no trailing slash
-#   CLAUDE_PLUGIN_OPTION_API_TOKEN     fmcp_ API key (sensitive)
-#   SCRIBE_URL / SCRIBE_TOKEN override for the settings.json dogfooding path.

+"""The report-shape check: does a reply that closed a task carry the completion
+sections, and what is it sent back with when it does not.
 
 WHY THIS EXISTS (milestone 409 step 5)
 
 Everything that helps an agent write a readable completion report arrives
-BEFORE the reply is written. A client's Stop hook is the one moment the
-finished reply exists, so it checks that a reply closing a task carries the
-completion sections (where the work sits, what needs the operator, what comes
-next), and reports what it found here. Two jobs live on this side:
+BEFORE the reply is written. The Stop hook is the one moment the finished reply
+exists, so a reply that closed a task is checked for the completion sections
+(where the work sits, what needs the operator, what comes next). Two jobs:
 
   - RECORDING the outcome, so the rate of `blocked` among checked replies is a
-    number milestone 409's last step can read rather than an impression.
-  - OWNING THE WORDS the agent is sent back with. A hook carries timing and
-    transport only (plugin/PACKAGING.md); guidance text comes from the server,
-    so a second client's hook gets the same instruction by calling the same
-    endpoint, and the wording changes in one place.
+    number rather than an impression (`category=plugin, action=report_check`).
+  - OWNING THE WORDS the agent is sent back with, so every client's hook says
+    the same thing (plugin/PACKAGING.md: hooks carry timing and transport).
+
+ONE END-OF-TURN REQUEST (milestone 500 step 4). This used to be a Stop hook of
+its own that checked the sections in shell and reported here; the reply-moment
+check sent the same reply to `/reply-rules` a moment later. The hook now sends
+the reply once, with the ids of the tasks the turn closed, and the section
+check runs here beside the reply hold. The patterns are the ones the shell
+used, matched on the words that carry the meaning rather than exact headings,
+so a shape's wording can change without breaking this.
 
 app_logs rather than a table of its own: one small event with a JSON detail is
 what that table holds, it already has retention and an admin viewer, and
-nothing here needs a join. If the numbers earn a readout, that is the moment to
-decide whether they earn a table.
