v0.5.1 — hooks-approval unmounted from default bundle

Repository: microsoft/amplifier-agent

Tag: v0.5.1

Prerelease: no

Release notes:

Highlights

`hooks-approval` is no longer mounted by default. Per the upstream USAGE_GUIDE — *"Backward compatible — Tools work without approval hook."* — the module is opt-in. The engine's default bundle had been mounting it unconditionally, which caused sub-session delegation to auto-deny any command that fell outside the bundled DEFAULT_RULES auto-approve list (e.g. cat, env, curl).

What changed

• Removed hooks-approval from the default bundle composition (src/amplifier_agent_lib/bundle/bundle.md)
• Updated admin/doctor.py to drop the hooks-approval presence check (it would have permanently failed post-unmount)
• Updated tests/test_admin_doctor_phase2.py to match the new doctor expectations
• Added ISSUES.md tracking the deferred work needed to re-wire hooks-approval end-to-end in the future (5 concrete pieces — see ISSUE-001)
• Bumped pyproject.toml: 0.5.0 → 0.5.1

The LICENSE is unchanged. Pre-PR 0.5.0-era sessions remain resumable but delegation flows will still hit the old auto-deny behavior on those sessions; start a fresh session to get the new behavior.

How to install

uv tool install --reinstall --force git+https://github.com/microsoft/amplifier-agent@v0.5.1

Compatibility

• Wire protocol: 0.3.0 (unchanged from 0.5.0)
• amplifier-agent-ts wrapper: >= 0.6.1
• Hosts: any caller using host_config.approval.mode = "yes" or passing -y works unchanged

Why this matters

For hosts running headless (paperclip, CI/CD), the engine no longer requires a separate hooks-approval registration step. For interactive CLI use, add hooks-approval to your profile per the USAGE_GUIDE.
