Think-Short

Install-only skill. It wires three self-contained hooks (SessionStart, UserPromptSubmit, PreToolUse:Task) that inject a terse-output prompt — or removes them. No on/off toggle, no profiles, no project-level config — only an ephemeral per-session counter in the OS temp dir (os.tmpdir()/brewtools-think-short/<session_id>.think-short-counter), auto-pruned. The hooks own all runtime behavior. This skill only decides install vs remove and project vs global, then delegates the file work to the brewcode:hook-creator agent following the runbook.

What the hooks do (informational — skill does NOT implement)

Hook	Behavior
SessionStart	inject the full terse prompt + reset the per-session counter
UserPromptSubmit	inject the full prompt every 10th user prompt (10/20/30…, not the 1st)
PreToolUse:Task|Agent	inject the full terse prompt into spawned subagents (coexistence-safe with other Task hooks)

BT_ROOT Resolver (use in EVERY bash block)

$CLAUDE_PLUGIN_ROOT is NOT inherited by the Bash tool in main-conversation slash invocations. Resolve dynamically:

BT_ROOT="${CLAUDE_PLUGIN_ROOT:-$(ls -d ~/.claude/plugins/cache/claude-brewcode/brewtools/*/ 2>/dev/null | sort -V | tail -1 | sed 's:/*$::')}"
test -d "$BT_ROOT/skills/think-short/assets" || { echo "❌ BT_ROOT invalid: $BT_ROOT"; exit 1; }

Asset paths (all under $BT_ROOT/skills/think-short/assets/):

• INSTALL.md — full install/remove runbook (project + global + remove)
• think-short-session.mjs, think-short-prompt-counter.mjs, think-short-task.mjs, think-short-prompt.md — the hook files that travel together

Never use Write/Edit on ~/.claude/* — protected path, blocked in ALL modes. Global install/remove runs through the Bash tool only (cp + node merge). The hook-creator agent handles this per the runbook.

---

Step 1 — Decide INTENT (install | remove)

Read $ARGUMENTS.

• Default = install.
• remove only if the prompt clearly says so: remove, uninstall, delete, убери, удали, выключи, сними, off, disable.
• Genuinely ambiguous → AskUserQuestion (options: Install / Remove).

Step 2 — Decide TARGET (project | global)

• Explicit global → global: global, глобально, for all projects, всех проектах.
• Explicit project → project: project, this repo, локально, здесь, этот проект.
• NOT specified → AskUserQuestion: "Install think-short for this Project or Globally?" (options: Project / Global). Do not auto-guess.

For remove with unspecified target, ask the same Project/Global question (or offer to clean both if the user says "everywhere").

Step 3 — State the plan, then delegate

Tell the user plainly what will happen, e.g.:

Installing think-short hooks (SessionStart + UserPromptSubmit + PreToolUse:Task) into <repo>/.claude/ and merging <repo>/.claude/settings.json.

Then verify assets and delegate to brewcode:hook-creator via the Task tool. Pass it: the chosen action (install|remove), the chosen target (project|global), the absolute runbook path, and the absolute assets source dir.

EXECUTE using Bash tool (resolve + print the absolute runbook and assets-dir paths to hand off):

BT_ROOT="${CLAUDE_PLUGIN_ROOT:-$(ls -d ~/.claude/plugins/cache/claude-brewcode/brewtools/*/ 2>/dev/null | sort -V | tail -1 | sed 's:/*$::')}"
test -d "$BT_ROOT/skills/think-short/assets" || { echo "❌ BT_ROOT invalid: $BT_ROOT"; exit 1; }
echo "ASSETS_DIR=$BT_ROOT/skills/think-short/assets"
echo "RUNBOOK=$BT_ROOT/skills/think-short/assets/INSTALL.md" && echo "✅ assets ok" || echo "❌ FAILED"

STOP if ❌ — plugin cache incomplete; reinstall/update brewtools first.

Spawn the agent (substitute ACTION, TARGET, RUNBOOK, ASSETS_DIR from above):

Task(subagent_type="brewcode:hook-creator", prompt="
Follow the runbook at RUNBOOK exactly — it self-locates its source via SRC=\$(dirname \"\$RUNBOOK\").
ACTION = ACTION (install|remove)
TARGET = TARGET (project|global)
RUNBOOK = RUNBOOK (absolute path to assets/INSTALL.md)
ASSETS_DIR = ASSETS_DIR (absolute path to the assets source dir — copy the 4 hook files FROM here)
Copy/merge or strip the 4 think-short hook assets per the runbook's marker convention, copying from ASSETS_DIR.
Project target: Write/Edit settings.json freely. Global target (~/.claude/*): BASH ONLY (cp + node merge), never Write/Edit — protected path.
Merge = append + dedupe by think-short-*.mjs script path. Remove = strip entries by those markers, drop empty event arrays, delete the 4 files.
Report which hooks were installed/removed and the exact settings.json path.
")

Step 4 — Report

After hook-creator returns, report:

• which hooks were installed/removed,
• the exact settings.json that changed (project or global path),
• reminder: a new session picks them up automatically — no /reload needed (plain settings.json hooks; SessionStart fires on next claude start / --resume).

Guards

Condition	Response
BT_ROOT resolves but $BT_ROOT/skills/think-short/assets missing	ERROR: think-short: assets not found under $BT_ROOT — plugin cache incomplete. STOP.
Neither $CLAUDE_PLUGIN_ROOT set nor any cached plugin dir found	ERROR: think-short: cannot locate plugin root — install/update brewtools first. STOP.
Intent ambiguous	AskUserQuestion: Install / Remove.
Target unspecified	AskUserQuestion: Project / Global.
Global target	Hook-creator MUST use Bash only (cp + node merge) — ~/.claude/* is protected.

Smoke Test

Verify the 4 assets exist and the scripts parse before delegating:

BT_ROOT="${CLAUDE_PLUGIN_ROOT:-$(ls -d ~/.claude/plugins/cache/claude-brewcode/brewtools/*/ 2>/dev/null | sort -V | tail -1 | sed 's:/*$::')}"
A="$BT_ROOT/skills/think-short/assets"
test -d "$A" || { echo "❌ assets dir missing"; exit 1; }
for f in think-short-session.mjs think-short-prompt-counter.mjs think-short-task.mjs think-short-prompt.md INSTALL.md; do
  test -f "$A/$f" || { echo "❌ missing $f"; exit 1; }
done
node --check "$A/think-short-session.mjs" && \
node --check "$A/think-short-prompt-counter.mjs" && \
node --check "$A/think-short-task.mjs" && \
echo "✅ smoke" || echo "❌ smoke FAILED"

Expected: ✅ smoke.
