README install: step 1 registers 'computer-use-behavior' but step 2 runs '--bundle computer-use' (not found)

[colombod]

Summary

The Install block in README.md is internally inconsistent. Step 1 registers the behavior sub-bundle (name computer-use-behavior), but step 2 — and the verification/troubleshooting lines — reference the root bundle name computer-use, which that step never registers. Following the README verbatim ends in Error: Bundle 'computer-use' not found.

Repo: microsoft/amplifier-bundle-computer-use @ eb26715 (main)
amplifier: 2026.08.05-5462f1e (core 1.6.1), Linux

Symptom (verbatim)

✓ Added app bundle 'computer-use-behavior'
  URI: git+https://github.com/microsoft/amplifier-bundle-computer-use@main#subdirectory=behaviors/computer-use.yaml

$ amplifier run --bundle computer-use "What's on my screen right now?"
Error: Bundle 'computer-use' not found. Available bundles: ... computer-use-behavior ...

Step 1 confirms the registered name is computer-use-behavior; the error's own "Available bundles" list contains computer-use-behavior but not computer-use.

Root cause

The repo ships two manifests with two names:

File	Line	Declared name
bundle.md (root)	bundle.md:3	computer-use
behaviors/computer-use.yaml	behaviors/computer-use.yaml:2	computer-use-behavior

README.md:43-51:

43  # 1. Register it (the name "computer-use" comes from this repo's own bundle.md)
44  amplifier bundle add git+.../amplifier-bundle-computer-use@main#subdirectory=behaviors/computer-use.yaml --app
47  amplifier run --bundle computer-use "What's on my screen right now?"
51  Confirm ... `amplifier bundle show computer-use` ...

The line-43 comment says the name comes from bundle.md, but the line-44 command adds behaviors/computer-use.yaml — whose name is computer-use-behavior. --bundle resolves by registered name, so lines 47/51 (and the trace example at README.md:289) reference a name step 1 never registers.

Fix (maintainer picks — depends on intended --app UX)

Option A — register the root bundle, keep --bundle computer-use (matches the line-43 comment):

- amplifier bundle add git+https://github.com/microsoft/amplifier-bundle-computer-use@main#subdirectory=behaviors/computer-use.yaml --app
+ amplifier bundle add git+https://github.com/microsoft/amplifier-bundle-computer-use@main --app

The root URI resolves bundle.md (name: computer-use), which includes the behavior, so steps 2 and the confirm line then work unchanged.

Option B — keep the behavior subpath, correct the name in run/confirm/trace lines:

- amplifier run --bundle computer-use "What's on my screen right now?"
+ amplifier run --bundle computer-use-behavior "What's on my screen right now?"

Note: an --app bundle is auto-composed into every session, so --bundle may be unnecessary in step 2 under this model. The local-clone variant at README.md:53 points at the repo root and likely already avoids this bug — a hint the GitHub line was meant to point at the root too.

Verification note (honest)

Directly verified: the two manifests declare the two different names; the user paste shows step 1 registering computer-use-behavior; --bundle matches by registered name. Not verified: a from-clean end-to-end re-run of Option A (on the investigation machine the root computer-use bundle was already registered by other means, so the pristine "not found" state could not be reproduced without disturbing the environment). Recommend a clean re-run of the chosen fix before merging.
