}What issue are you seeing?
When Codex runs inside a git worktree (.git is a file, not a directory), project-level hooks defined in <worktree-root>/.codex/hooks.json are silently not loaded or executed. Only user-level hooks from ~/.codex/hooks.json fire.
I tested three projects on the same machine with identical user-level hooks config:
| Project | .git type | Project hooks.json SessionStart hooks | Actual SessionStart hooks fired |
|---------|------------|----------------------------------------|-------------------------------|
| test_case | directory (normal repo) | 1 | 3 (2 user + 1 project) |
| crm_space | file (worktree) | 2 | 2 (user only, 0 project) |
| infra_product | file (worktree) | 2 | 2 (user only, 0 project) |
Key observations:
--dangerously-bypass-hook-trustdoes not change the result — still only 2 hooks in worktree mode. This rules out a trust issue.codex doctorcorrectly identifies the worktree as a project (project source: git repo root, showing the worktree path).- The
.codex/hooks.jsonfile exists and is valid JSON at the worktree root. infra_producthas 13trusted_hashentries in~/.codex/config.tomlfor its project hooks — they still don't fire.
No error messages are shown. The project hooks are simply not discovered.
What steps can reproduce the bug?
# 1. Create a repo with a worktree
cd /tmp && mkdir hook-repro && cd hook-repro
git init main && cd main
git config user.email "test@test.com" && git config user.name "test"
echo "hello" > file.txt && git add . && git commit -m "init"
git worktree add ../wt -b feature
# 2. Add project-level hooks to the worktree
cd ../wt
mkdir -p .codex
cat > .codex/config.toml << 'EOF'
[features]
hooks = true
EOF
cat > .codex/hooks.json << 'EOF'
{
"hooks": {
"SessionStart": [
{
"matcher": "",
"hooks": [
{
"type": "command",
"command": "echo PROJECT_HOOK_FIRED >> /tmp/codex-hook-probe.log"
}
]
}
]
}
}
EOF
# 3. Run codex in the worktree
rm -f /tmp/codex-hook-probe.log
codex exec --dangerously-bypass-hook-trust "echo hello"
# 4. Check
cat /tmp/codex-hook-probe.log
# Expected: contains "PROJECT_HOOK_FIRED"
# Actual: file does not exist — project hook never fired
# 5. Compare: do the same in the main (non-worktree) repo
cd ../main
mkdir -p .codex
cp ../wt/.codex/config.toml .codex/
cp ../wt/.codex/hooks.json .codex/
rm -f /tmp/codex-hook-probe.log
codex exec --dangerously-bypass-hook-trust "echo hello"
cat /tmp/codex-hook-probe.log
# Result: contains "PROJECT_HOOK_FIRED" ✓What is the expected behavior?
Project-level .codex/hooks.json placed at the worktree working tree root (the path returned by git rev-parse --show-toplevel) should be discovered and loaded, the same way it works in a normal (non-worktree) repository.
Additional information
Root cause hypothesis: In a git worktree, .git is a file containing gitdir: /path/to/.git/worktrees/<name>. The hooks discovery code likely resolves the project root by looking for a .git directory, or by using git rev-parse --git-common-dir (which returns the main repo's .git path), instead of using git rev-parse --show-toplevel (which correctly returns the worktree working tree root). This causes the hooks scanner to look for .codex/hooks.json at the wrong location.
Evidence supporting this: I found a stale trusted_hash entry in ~/.codex/config.toml keyed to a .codex/hooks.json path at the bare repo cache parent directory (where --git-common-dir resolves), not at the worktree working tree — suggesting codex previously resolved the hooks config path to that location.
Workaround: Register hooks at the user level (~/.codex/hooks.json) instead of project level. User-level hooks fire correctly regardless of worktree status.
