Close instance ports from the CLI

[callen-bot]

Summary

• add brev ports close <instance-or-node> with a remove alias
• present an interactive picker for human use and support exact --id <port_id> --approve targeting for automation
• add --all to close every current mapping, with confirmation unless --approve is supplied
• support managed instances and registered nodes, including partial-failure reporting
• direct automation to brev ports ls <instance-or-node> --json for stable IDs
• mark brev ports close as beta and hide it from help and completion

Why

PR #441 adds the read layer and PR #442 adds the create layer. This stacked follow-up completes the delete layer for port mappings.

Impact

Users can remove one selected mapping, deterministically remove one mapping by its unique API ID, or remove all mappings in a single command.

Visibility

The brev ports command family is intentionally hidden from help and completion while its final naming and nesting are being discussed, including whether it should use a different name or live under a network-oriented parent. Exact commands remain callable so the implementation can be tested. This PR hides close and inherits the hidden group, list, and create commands from #442.

Stack

• Base: Create instance ports from the CLI #442
• This PR: delete/close operations
• Follow-up: Update instance ports from the CLI #447 adds true in-place update/edit operations

Validation

• go test ./pkg/cmd ./pkg/cmd/ports
• go test -race ./pkg/cmd/ports ./pkg/cmd
• go build -o /tmp/brev-port-restack-close-brev .
• help smoke tests confirm the ports group and all commands through close remain hidden but callable explicitly

Summary by CodeRabbit

• New Features

  • Added brev ports close for closing ports interactively, by exact port ID, or in bulk.
  • Added confirmation prompts and support for closing ports on instances and external nodes.
  • Added the remove alias for the close command.
  • Added clear success and failure reporting, including partial-failure handling.

• Documentation

  • Added command usage, options, constraints, and examples for closing ports.

• Bug Fixes

  • Improved port resolution and filtering to prevent non-removable ports from being selected.

Walkthrough

The ports CLI adds a hidden close command with interactive, exact-ID, and bulk modes. It resolves workspace and node targets, filters removable ports, requests approval, closes ports through the matching service, reports results, and documents the command.

Changes

Port closing workflow

Layer / File(s)	Summary
Command registration and target resolution pkg/cmd/ports/ports.go, pkg/cmd/ports/ports_test.go, pkg/cmd/ports/close.go	The ports command registers hidden close support. Target and port retrieval now use resolveTargetPorts, which returns the resolved target and port list.
Port selection, approval, and closure pkg/cmd/ports/close.go, pkg/cmd/ports/close_test.go	The command supports interactive, exact-ID, and --all selection. It filters invalid entries, handles approval and cancellation, dispatches to environment or node services, and aggregates failures. Tests cover these flows and validation cases.
CLI documentation .agents/skills/brev-cli/SKILL.md, .agents/skills/brev-cli/reference/commands.md	The documentation describes the command, alias, flags, constraints, lookup method, and examples.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: ⚪ Minimal · up to 915b4

The port-closing CLI changes are merge-ready after normal checks; no actionable merge-blocking risk remains. A localized documentation formatting cleanup is still advisable.

Poem

I’m a rabbit with ports to close,
I pick the ones the prompt shows.
IDs hop neatly, approvals shine,
Nodes and workspaces fall in line.
Failures report; successes cheer—
The CLI burrows cleanly here!
