Problem

A fleet attach command copied out of the Cloud dashboard —

agent-relay node agent attach '<agent>' --node '<node>' --mode <mode>

— is only useful if it works wherever it is pasted. Today it does not, and the reason is not the local broker connection.json (the --node path never reads it). --node authenticates with the Relaycast workspace key, resolved through the ladder in resolveWorkspaceSelection:

flag > env > <project>/.agentworkforce/relay/workspace-key.json > machine-global store

agent attach exposed no flag, so the top rung was unreachable. Reproduced against the installed CLI (v11.5.5):

where it runs result
dir whose repo pins a different workspace Error: Invalid API key — the project pin outranks the global active entry
machine with no pin and no global active entry Error: No workspace key found. Pass --workspace-key, ...
agent attach ... --workspace-key <key> error: unknown option '--workspace-key'

The error message names a flag the command rejects. And the obvious-looking workaround does not exist either — --node is mutually exclusive with --broker-url / --api-key / --state-dir, because those configure a local broker that this path has no use for.

Fix

Add --workspace-key <key> to node agent attach and thread it into startFleetNodeAttachProxy. FleetNodeAttachOptions.workspaceKey already existed and already took precedence over the environment — only the CLI surface was missing.

  • Accepted only with --node. The local and --ssh-host paths speak the broker contract, so accepting it there would resolve nothing and quietly point the caller at the wrong workspace. Rejected with a message that says which flags those paths use instead.
  • A blank/whitespace value falls through to the ladder rather than being presented as a literal credential.
  • attachNode now takes FleetNodeAttachCliOptions rather than NativeAttachOptions, so the type stops advertising the three broker fields this path rejects at parse time.

Verification

  • Red-check: the four new CLI tests fail against unmodified source (CommanderError: unknown option '--workspace-key') and pass after. The 38 pre-existing tests in those files stay green throughout.
  • The two attach-fleet-node tests are precedence regression guards, not novelty proofs — they pass before and after, because that plumbing already worked. They pin explicit-key-beats-env so a later refactor cannot quietly invert it.
  • npm run typecheck exits 0.
  • npx eslint — 0 errors. One pre-existing complexity warning on the attach action rises 20 → 24; lint runs without --max-warnings, so this does not fail CI. Splitting that action is left out to keep this diff to the defect.

Note on scope

This is the enabling half. The dashboard side (whether the generated command should embed a key, or carry a one-time agent-relay workspace join hint instead) is a separate call in AgentWorkforce/cloud — embedding rk_live_… in a copy-pastable UI string is a credential-handling decision, not a mechanical one.

Review in cubic

…-key

A fleet attach command copied out of the Cloud dashboard is only portable
if it resolves the same workspace wherever it is pasted. Today it does not:
`--node` authenticates with the Relaycast workspace key, which comes from
the precedence ladder in `resolveWorkspaceSelection` —

  flag > env > <project>/.agentworkforce/relay/workspace-key.json > machine-global

— and the attach command exposed no flag, so the top rung was unreachable.
Run the same command inside a checkout pinned to a different workspace and
it silently addresses that one instead ("Invalid API key", or worse, a
successful call against the wrong workspace). Run it on a machine with no
pin and no global active entry and it fails with

  Error: No workspace key found. Pass --workspace-key, ...

naming a flag `agent attach` rejected with `unknown option '--workspace-key'`.

Add the flag and thread it into `startFleetNodeAttachProxy`, whose
`FleetNodeAttachOptions.workspaceKey` already existed and already took
precedence over the environment — only the CLI surface was missing.

- `--workspace-key` is accepted only with `--node`. The local and
  `--ssh-host` paths speak the broker contract and authenticate with
  `--broker-url` / `--api-key`, so accepting it there would resolve
  nothing and quietly send the caller to the wrong place.
- A blank value falls through to the ladder rather than being presented
  as a literal credential.
- `attachNode` now takes `FleetNodeAttachCliOptions` instead of
  `NativeAttachOptions`, so the type no longer advertises the three
  broker fields the `--node` path rejects at parse time.

Verified: the four new CLI tests fail against unmodified source with
`unknown option '--workspace-key'` and pass after. The two proxy tests are
precedence regression guards — that plumbing already worked.

📝 Walkthrough

Walkthrough

Changes

The CLI adds optional --workspace-key support for --node attachment. It trims blank values, rejects invalid usage, forwards defined keys, documents the behavior, and verifies precedence over RELAY_WORKSPACE_KEY.

Fleet node workspace-key flow

Layer / File(s) Summary
Fleet attachment contract and forwarding
packages/cli/src/cli/commands/local-agent.ts, packages/cli/src/cli/lib/attach-fleet-node.test.ts
Fleet attachment options include workspaceKey. Explicit keys take precedence over RELAY_WORKSPACE_KEY.
CLI option validation and node wiring
packages/cli/src/cli/commands/local-agent.ts, packages/cli/src/cli/commands/local-agent.test.ts, CHANGELOG.md, .agentworkforce/trajectories/...
The CLI trims workspace keys, rejects them without --node, forwards defined values, and records the behavior and review decision.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 08bf8

The command now accepts an explicit workspace key for fleet-node attachment while keeping broker-based paths separate; merge is reasonable with owner awareness that blank-key handling should still receive a path-specific error-guidance regression assertion.

A rabbit sends a workspace key,
To fleet nodes quick and sleek.
Blank keys vanish; wrong paths warn,
Explicit keys lead at dawn.

Hop, hop, attach without fail!

…path

Review follow-up on #1502. Two defects in the guard that restricts
`--workspace-key` to the `--node` path.

The guard tested the normalized value, not the option. `--workspace-key
"$KEY"` with an unset or whitespace-only variable trims to `undefined`
before the check runs, so the command fell through to the local or
`--ssh-host` attach path and silently ignored a flag the caller
explicitly passed — attaching against whatever broker happened to be
configured instead of saying no. Gate on the raw option; keep
normalizing to `undefined` on the `--node` path, where a blank value
should still fall through to the precedence ladder rather than be sent
as a literal credential.

The rejection message then named the wrong flags for half its audience.
It told every rejected caller to use `--broker-url` / `--api-key`, but
`--ssh-host` rejects exactly that combination two branches later and
wants `--state-dir` — so following the advice produced a second,
contradictory error. Split the guidance by path.

Verified: all four new tests fail against the previous commit —
the two blank-value cases reach `attach` / `attachRemote` instead of
erroring, and both message assertions read back the old single string.
All 46 tests in the two files pass after. `npm run typecheck` exits 0;
`npx eslint` reports 0 errors (the pre-existing complexity warning on
the attach action rises 24 → 25).

Also records the CLI change in `CHANGELOG.md` under `[Unreleased -
Patch]`, which the original commit left out.

193-214: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Cover path-specific guidance for blank values.

These tests verify rejection and handler suppression, but they do not verify the corrected guidance for the same blank inputs. Add the local broker flag assertions to the local test and the --state-dir assertions to the SSH test. This prevents a regression that rejects blank values but returns contradictory guidance.

Suggested assertions
+    const message = error.mock.calls.at(0)?.[0] as string;
+    expect(message).toContain('--broker-url');
+    expect(message).toContain('--api-key');
+    expect(message).not.toContain('--state-dir');

This follows the PR objective that blank values are rejected outside --node and that error guidance is path-specific.
