Three defects, each of which independently made a hook a no-op, and all three failing silently — which is why the whole dynamic side of the plugin looked "shipped" while doing nothing. 1. Wrong env var case. Claude Code exports userConfig to hooks as CLAUDE_PLUGIN_OPTION_<KEY> with the key UPPERCASED. All four hooks read CLAUDE_PLUGIN_OPTION_api_endpoint / _api_token, so both values were always empty. That killed the SessionStart dynamic tier, process sync, prompt auto-inject, and the write-path prior-art trigger at once. 2. jq -rR is line-oriented. `@uri` under -R encodes input LINE BY LINE, so a multi-line payload came back as several encoded lines joined by raw newlines — an invalid URL, curl fails, hook exits 0 in silence. Now -sRr. This one hid behind (1): auto-inject only ever worked for single-line prompts, and prior-art (which posts code, always multi-line) could never have worked at all. 3. cut -c1-1200 caps each LINE, not the payload, so the prior-art code budget wasn't a budget. Now head -c 1200. Also widens the SessionStart warning: "neither URL nor token arrived" used to be treated as a benign unconfigured install and stayed quiet. That is exactly the state defect (1) produced, so the one install state that most needed a signal was the only one that emitted none. It now says so, and names the two other features it silently disables. Verified against the live instance: dynamic rules + project context load, auto-inject surfaces #2192 on a multi-line prompt, and the write-path trigger returns the [here] place-arm hit on a multi-line edit with session dedup suppressing the repeat.

# Scribe plugin — UserPromptSubmit push channel (knowledge auto-inject, Path A).

# On each user prompt, asks the operator's Scribe instance for a TITLE-FIRST

# awareness hint: the few notes that clear the per-user auto-inject gates

|
# (high-confidence threshold, margin gate, session dedup, top-k). Titles + ids

# Best-effort enrichment ONLY: unlike the SessionStart channel there is no
