Code Example

I queried Codex’s hooks/list RPC directly:

  - For one cwd, Codex returns 5 preToolUse hooks from ~/.codex/hooks.json.
  - For two cwds, Codex returns two entries, each with the same 5 global user hooks.
  - If the UI flattens those per-cwd results, it shows 10 rows: 1-5 repeated as 6-10.

  So the duplicate list is effectively:

  cwd A: ~/.codex/hooks.json preToolUse 0..4
  cwd B: ~/.codex/hooks.json preToolUse 0..4

  The source path and keys are identical in both copies, for example:

  ~/.codex/hooks.json:pre_tool_use:0:0
  ~/.codex/hooks.json:pre_tool_use:1:0
  ~/.codex/hooks.json:pre_tool_use:2:0
  ...

  So expected runtime config is still 5 PreToolUse hooks per cwd, not 10. The 10-row view looks like a Codex TUI/app listing bug or UX issue: it is showing global user hooks once per cwd instead of grouping or deduping them

What issue are you seeing?

I can see duplicate hooks, like i have 5 hooks, but it shows 10 in codex cli settings. e.g. PreToolUse with 5 hooks, then 6-10 are simply duplicating 1-5.

What steps can reproduce the bug?

codex --cd "$PWD"

What is the expected behavior?

only show expected global hooks without duplication
