Get Homer installed
The guided setup is the quickest route. Open it on the same Windows or macOS machine where Cursor, Claude Code, or Codex runs. Setup ends with a controlled 60-second guided activation review, not an ordinary first check.
- Create your account and verify your email.
- Copy and run the install command for your computer.
- Close and restart your coding agent after the command finishes, then start a new agent task.
- Copy the guided activation prompt from setup into that new task. The first Homer result is expected to pause and name one checklist improvement.
- Let the agent make that edit, then retry Homer in the same agent task with the
retry_scope_idfrom the first result. A different task cannot complete the review. - Wait for setup to show Homer as activated.
Timing and usage: the guided review expires 24 hours after its install command is created. If it expires, return to setup and create a new install command. Guided-review calls are activation checks, so they do not appear as ordinary usage on the Account page.
Review the hook for your agent
Codex
After restarting Codex, open /hooks. Find the Homer PreToolUse hook, inspect its current command and definition, and approve that exact definition if Codex prompts you. Codex records trust for the definition's current hash; if the definition changes, Codex can require another review.
hook context not observed means only that Homer's Codex PreToolUse hook did not run for that check. It does not prove the hook is unapproved. The hook may be disabled, its definition may have changed, or the task may predate the current install. Review /hooks, then start a new task and retry. If the Homer hook is absent, rerun the installer first.
Cursor
Restart or reload Cursor. If Cursor asks to review Homer hooks, inspect and trust the Homer PreToolUse hook; it attaches the current Cursor transcript path to Homer checks. If Homer still cannot see the full Cursor session, confirm Cursor transcripts are enabled, restart or reload, and retry in the same workspace.
Claude Code
Restart Claude Code. If it asks to review Homer hooks, inspect and trust the Homer PreToolUse hook; it attaches the current Claude transcript path, session ID, and working directory to Homer checks. Start the guided review in the restarted session.
