Addresses review feedback on PR #1817:
1. Extend the `_agent_dir_from_hermes_cli` docstring to spell out that
the shebang fallback is a last-resort discovery step, not an override.
Stale clones in known candidate paths still win — same precedence as
today, but now documented so a future maintainer doesn't get the
wrong idea.
2. Drop the misleading "install exists but no run_agent.py" comment in
`test_returns_none_when_shebang_interpreter_does_not_walk_to_run_agent`.
The test exercises a shebang pointing at /usr/bin/python3 whose
parents never reach a run_agent.py — it doesn't actually need a fake
install dir at all. Renamed for accuracy and removed the unused
_make_agent_install call.
`discover_agent_dir()` only checked four hard-coded layouts:
- HERMES_WEBUI_AGENT_DIR
- $HERMES_HOME/hermes-agent
- <webui-parent>/hermes-agent
- ~/.hermes/hermes-agent / ~/hermes-agent
Users who clone hermes-agent somewhere else (e.g. ~/Projects/GitHub/hermes-agent)
hit:
[bootstrap] ERROR: Python environment cannot import both WebUI dependencies
and Hermes Agent. Set HERMES_WEBUI_PYTHON to the Hermes Agent venv Python
or install the WebUI requirements into that environment.
…even though the `hermes` CLI is on PATH and works fine. The CLI is a
console-script with a venv-relative shebang:
#!/path/to/hermes-agent/venv/bin/python3
After the explicit candidates miss, fall back to introspecting that shebang
and walking up parents until we find `run_agent.py`. That's a reliable
pointer to the install root regardless of where the user cloned the repo.
Tests cover happy path, no `hermes` on PATH, missing/invalid shebang,
shebang pointing outside any agent install (e.g. /usr/bin/python3), and
explicit candidates winning over the shebang fallback.
Verified end-to-end: with hermes-agent at a non-standard path,
`uv run bootstrap.py` now succeeds without any HERMES_WEBUI_AGENT_DIR
override.
