Groove Admin Cursor Hooks

<!-- groove:managed — do not edit; changes will be overwritten by groove update -->

groove-admin-cursor-hooks

Install groove's Cursor native hooks. These run outside the model — deterministic, unconditional — and complement groove's advisory markdown hooks (.groove/hooks/start.md, end.md).

Use --disable <hook> to remove a specific hook. Use --list to show current status.

Outcome

Selected hooks are registered in .cursor/hooks.json and shell scripts are written to .groove/hooks/cursor/. Hooks fire automatically on Cursor lifecycle events without any model involvement.

Available hooks

Steps

--list

Read .cursor/hooks.json if it exists. Report which groove hooks are registered and which scripts exist in .groove/hooks/cursor/. Exit.

--disable <hook>

Remove the named hook's entry from .cursor/hooks.json (leave the script in place). Report removed / not found. Exit.

Default (install)

1. Ask which hooks to enable (default: all six): `` Which hooks to install? (all / comma-separated: context-reprime, daily-end-reminder, git-activity-buffer, block-managed-paths, version-check, session-capture) Press enter for all. ``

1. Read .cursor/hooks.json if it exists; parse as JSON (default {"version": 1, "hooks": {}}). Never discard existing non-groove entries.

1. Create .groove/hooks/cursor/ directory if absent. Make each script executable (chmod +x).

1. For each selected hook: write the shell script and merge the hook entry into .cursor/hooks.json.

1. Write .cursor/hooks.json with the merged result.

1. Report summary: `` ✓ context-reprime — sessionStart hook → groove-utilities-prime.sh --json ✓ daily-end-reminder — stop hook → .groove/hooks/cursor/daily-end-reminder.sh ✓ git-activity-buffer — postToolUse/Shell hook → .groove/hooks/cursor/git-activity-buffer.sh ✓ block-managed-paths — preToolUse/Write hook → .groove/hooks/cursor/block-managed-paths.sh ✓ version-check — postToolUse hook → .groove/hooks/cursor/version-check.sh ✓ session-capture — stop hook → .groove/hooks/cursor/session-capture.sh ✓ .cursor/hooks.json updated ``

Shell script templates

Write these verbatim to .groove/hooks/cursor/. Never overwrite an existing script without showing a diff and confirming.

daily-end-reminder.sh

#!/usr/bin/env bash
# groove: stop hook — remind about /groove-daily-end during work hours
hour=$(date +%H)
if [ -f "$CLAUDE_PROJECT_DIR/.groove/index.md" ] && [ "$hour" -ge 16 ] && [ "$hour" -le 21 ]; then

git-activity-buffer.sh

input=$(cat)
command=$(echo "$input" | python3 -c "import sys,json; d=json.load(sys.stdin); print(d.get('tool_input',{}).get('command',''))" 2>/dev/null)

  msg=$(echo "$command" | grep -oP '(?<=-m ")[^"]+' | head -1)
  mkdir -p "$CLAUDE_PROJECT_DIR/.groove/.cache"

session-capture.sh

#!/usr/bin/env bash

# No activity → clear any stale draft and stay silent.
if [ -z "$commits" ] && [ -z "$changes" ] && [ -z "$buffered" ]; then
  rm -f "$PENDING"
  exit 0
fi

mkdir -p "$CACHE"
{

.cursor/hooks.json template

Merge these into the hooks key. Preserve all other keys.

{
  "version": 1,
  "hooks": {
    "sessionStart": [
      {
        "command": "bash $CLAUDE_PROJECT_DIR/.agents/skills/groove-utilities-prime/scripts/groove-utilities-prime.sh --json"
      }
    ],
    "stop": [
      {
        "command": "bash $CLAUDE_PROJECT_DIR/.groove/hooks/cursor/daily-end-reminder.sh"
      },
      {
        "command": "bash $CLAUDE_PROJECT_DIR/.groove/hooks/cursor/session-capture.sh"
      }
    ],
    "postToolUse": [
      {
        "matcher": "Shell",
        "command": "bash $CLAUDE_PROJECT_DIR/.groove/hooks/cursor/git-activity-buffer.sh"
      },
      {
        "command": "bash $CLAUDE_PROJECT_DIR/.groove/hooks/cursor/version-check.sh"
      }
    ],
    "preToolUse": [
      {
        "matcher": "Write",
        "command": "bash $CLAUDE_PROJECT_DIR/.groove/hooks/cursor/block-managed-paths.sh"
      }
    ]
  }
}

When merging: if a hooks key already exists, append groove entries to the relevant event arrays. Do not create duplicates — check if a groove command entry already exists before appending.

Constraints

• Never overwrite non-groove entries in .cursor/hooks.json
• Never overwrite an existing script without diff + confirmation
• Scripts use python3 to parse JSON stdin — if python3 is absent, skip that hook and warn
• block-managed-paths uses exit code 2 (Cursor's convention to block the tool use)
• After install: remind the user that hooks take effect on the next Cursor session restart
