What it does

Git Worktree Precommit Hook Flutter Failure is an agent skill from divinevideo/divine-mobile. Fix git pre-commit hook failures in Flutter projects when using git worktrees. Use when: (1) Pre-commit hook with flutter analyze fails during git commit but passes when run manually, (2) Hook output shows "Resolving dependencies..." then immediately fails with no actual analysis errors, (3) Working in a git worktree (created via git worktree add). Root cause: git sets GITDIR to a worktree-style path during hook execution, which breaks flutter pub get (called internally by flutter analyze). Fix: unset GITDIR…

Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Git worktrees and Cross-platform mobile apps. It works with Git and Flutter. The licence is MPL-2.0.

When your agent uses it

  • Pre-commit hook with flutter analyze fails during git commit but passes when run manually
  • Hook output shows Resolving dependencies... then immediately fails with no actual analysis errors
  • Working in a git worktree (created via git worktree add)

Example prompts

  • “Resolving dependencies...”
  • “/git-worktree-precommit-hook-flutter-failure”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Make a change in a git worktree
  2. Stage the file: git add
  3. Commit: git commit -m "test" — hook should pass
  4. Verify the same hook still works in the main repo checkout

What it can do on your machine

Read from SKILL.md and the folder at commit 8d5fbf2. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • flutter
    • git
    • dart

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Git Worktree Precommit Hook Flutter Failure loads about 1k tokens when it runs. Until then it costs about 162 tokens; SKILL.md has 328 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~162
When it runs · the whole SKILL.md, loaded when a task matches
~1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Git Worktree Pre-Commit Hook Flutter Failure

Problem

When using git worktree for parallel development, pre-commit hooks that run flutter analyze fail during git commit even though:

  • Running flutter analyze directly in the worktree passes with no issues
  • Running the pre-commit hook script manually passes
  • The hook passes in the main repo checkout

Root Cause

Git sets GIT_DIR, GIT_INDEX_FILE, and GIT_WORK_TREE environment variables during hook execution. In a worktree, GIT_DIR points to .git/worktrees/<name>/ instead of .git/. When flutter analyze internally runs flutter pub get, pub chokes on this worktree-style GIT_DIR path and fails to resolve dependencies.

The failure is invisible when the hook uses 2>/dev/null on stderr — you only see "Resolving dependencies..." then the failure message, with the actual error suppressed.

Context / Trigger Conditions

  • Using git worktree add for parallel branch development
  • Pre-commit hook runs flutter analyze or dart analyze
  • Hook output shows "Resolving dependencies..." then immediately fails
  • No actual analysis errors are reported
  • The hook uses set -e (exit on error)
  • 2>/dev/null may hide the actual failure cause

Diagnosis

Reproduce the exact failure by simulating git's hook environment:

bash
# This will FAIL (simulates hook execution in worktree)
GIT_DIR=/path/to/main/.git/worktrees/<name> \
  flutter analyze --no-fatal-infos 2>/dev/null

# This will PASS (without git env vars)
flutter analyze --no-fatal-infos

Solution

Add unset GIT_DIR GIT_INDEX_FILE GIT_WORK_TREE to the pre-commit hook after all git commands but before any flutter/dart commands.

bash
#!/bin/bash
set -e

cd "$(git rev-parse --show-toplevel)/mobile"

# Git operations (these NEED the git env vars)
STAGED_DART_FILES=$(git diff --cached --name-only --diff-filter=ACM | grep '\.dart$' || true)

if [ -z "$STAGED_DART_FILES" ]; then
    echo "No Dart files staged, skipping checks"
    exit 0
fi

# Unset git env vars BEFORE running flutter/dart commands.
# Git sets these during hook execution, and flutter pub get
# (called internally by flutter analyze) chokes on worktree-style
# GIT_DIR paths.
unset GIT_DIR GIT_INDEX_FILE GIT_WORK_TREE

# Now flutter/dart commands work in both main repo and worktrees
dart format --output=none --set-exit-if-changed lib test
flutter analyze --no-fatal-infos

Key points:

  • The unset MUST come after git diff --cached (which needs GIT_INDEX_FILE)
  • The unset MUST come before flutter analyze and dart format
  • Remove 2>/dev/null from flutter analyze so errors are visible

Verification

  1. Make a change in a git worktree
  2. Stage the file: git add <file>
  3. Commit: git commit -m "test" — hook should pass
  4. Verify the same hook still works in the main repo checkout

Notes

  • This affects any tool that internally runs pub get or interacts with git during hook execution (not just flutter analyze)
  • dart format may also be affected in some configurations
  • The git rev-parse --show-toplevel call at the top of the hook works correctly with GIT_DIR set — it resolves to the worktree root
  • Only unset the vars when you're done with git operations
