Problem and resulting behavior

Background consumers such as ATC need worktree membership, then observe Git themselves. Existing recursive list/status perform branch and dirty-state probes that those consumers repeat. Also, running list inside .worktrees/NAME could return an empty listing instead of describing the current set.

Extend the existing list API: list [NAME] selects an explicit set, defaults to the enclosing set inside .worktrees/NAME or any descendant, and lists all configured sets outside a worktree. --metadata-only controls observation detail independently of selection and recursion. The earlier unreleased members command is removed in favor of this API.

Before and after usage

Before, topology-only callers used detailed Git status:

meta git worktree status example --recursive --json

Now they can select exactly one set without Git-state probes:

meta git worktree list example --recursive --metadata-only --json

From .worktrees/example/ or any descendant, including a nested repository:

meta git worktree list
meta git worktree list --recursive
meta git worktree list --recursive --metadata-only --json

The first two retain branch/dirty summaries; the last returns aliases and checkout/source paths. Explicit NAME overrides inferred selection. Without NAME outside a worktree, list still enumerates all sets. status NAME remains the detailed Git-state command, including modified files, untracked counts and ahead/behind information.

Output and error contract

The JSON envelope remains worktrees, even for one selected set. Illustrative metadata-only output:

{
  "worktrees": [{
    "name": "example",
    "root": "/work/harmony/.worktrees/example",
    "has_meta_root": true,
    "repos": [{
      "alias": ".",
      "path": "/work/harmony/.worktrees/example",
      "source_path": "/work/harmony"
    }]
  }]
}

Metadata-only omits branch/dirty/ahead-behind fields and launches no Git probes. Available set lifecycle metadata is retained. Without that flag, existing observed repository fields are preserved. --recursive includes nested realized repositories; omitting it retains legacy traversal boundaries.

Missing, empty or invalid selected sets fail instead of returning a misleading empty/partial success. Recursive all-set listing preserves healthy sets and reports failed sets in warnings. Consumers must check warnings before treating an aggregate inventory as complete. Inference uses a path-only location hint, so invalid enclosing metadata cannot silently select another root.

Dependencies and validation

Requires meta_cli #35. Consumer: ATC #554. Documentation: Meta #100.

• 71 plugin unit tests and four public protocol tests passed; Meta library suite passed 101 tests. Formatting, whitespace and strict all-target Clippy passed.
• Protocol coverage includes selected/inferred/all-set listing, explicit and forwarded recursion, existing observed output, metadata-only with zero Git calls, malformed selected roots, selected errors and aggregate warnings.
• Installed CLI verified on the real 14-repository Harmony set: explicit and inferred output match from root and deep descendants. Plain list also selects the current set.
• One wall-clock sample using /usr/bin/time -p, same set and 14 repositories: recursive observed list 1.17s; metadata-only list 0.35s. These are local samples, not benchmark averages or crash-prevention evidence.

Summary by CodeRabbit

• New Features
  • Worktree listings now default to the set containing your current directory; outside a worktree, they show all configured sets. You can also select a set by name.
  • Use --metadata-only to list repository membership paths without Git status details.
  • JSON listings include worktree results and, when applicable, warnings.
• Bug Fixes
  • Listings now report errors for missing or invalid selected worktrees, while aggregate listings can still show healthy sets when another set has a problem.

Review corrections

Commit 52e1322 threads protocol request.cwd through typed worktree dispatch into list selection/root resolution, without process-wide chdir. The executable fixture now starts the process in the source directory while requesting the worktree root/deep descendant. The zero-Git metadata-only fixture also includes a valid nested checkout and verifies aliases, paths and canonical source paths for both members. All 71 unit and four protocol tests and strict all-target Clippy passed; both review threads have responses with evidence.

Help follow-up 9a6bd02 separates LIST OPTIONS and REMOVE OPTIONS. Public executable help smoke and formatting passed; the follow-up thread is resolved.

Walkthrough

The worktree list command can select a named worktree or infer one from the request directory. It supports metadata-only membership listing, observed Git status output, and JSON or text results with warnings.

Changes

Worktree List

Layer / File(s)	Summary
List contract and dispatch src/commands/worktree/cli_types.rs, src/commands/worktree/mod.rs, src/lib.rs	The list command accepts an optional worktree name and a metadata-only option. Dispatch passes request options and cwd to the handler. Help describes selection defaults and metadata-only output.
Selection, discovery, and output src/commands/worktree/list.rs, tests/recursive_inventory.rs	The handler selects a worktree from its name or request directory. It emits metadata-only membership paths or observed Git status, and reports warnings for eligible all-worktree listing errors. Protocol tests cover selection, output, and malformed membership.

The command help may lead users to try --metadata-only with status, which does not accept it. This is a bounded documentation issue; the change is mergeable with a help-text correction.

Full details: Title check

Explanation

The title "feat(worktree): add contextual metadata-only listing" matches the main change. The PR adds contextual selection for meta git worktree list [NAME], which infers the enclosing set from the current worktree. It also adds --metadata-only output that skips Git probes. The title names both primary features. It omits the removal of the members command and the recursion and warning changes, which is acceptable for a title.
