## Description
### Motivation
File-based stdio MCP servers spawned from a project's `.mcp.json` (e.g. `pnpm run mcp:foo`, or anything using `./tooling_scripts/...`) fail with:
```
Transport creation error: No such file or directory (os error 2)
```
Root cause: when the user's `.mcp.json` doesn't include a `working_directory`, Warp's spawner inherits whatever cwd Warp was launched from rather than the directory the config was discovered in. Two failure modes share this same root cause:
- **Repo-relative commands/args** (e.g. `./tooling_scripts/foo`, `node ./src/server.js`) can't be resolved from outside the repo, so `execvp` returns `ENOENT`.
- **Workspace-aware launchers** like `pnpm`/`npm`/`yarn` walk up from cwd looking for `package.json` (and workspace manifests). When cwd isn't inside the repo, they bail out before launching the requested script — surfacing as `ENOENT` from the spawner's perspective.
`working_directory` is a Warp/VS-Code-style extension; the canonical Anthropic/Cursor MCP schemas don't include it, so most `.mcp.json` files in the wild don't set it.
### Implementation
- New helper `FileBasedMCPManager::spawn_root_for_installation(uuid)` returning the discovery root for any file-based install: the repo root for project-scoped configs, the home directory for global configs (Warp and third-party). Returns `None` for non-file-based installs (e.g. cloud-templated ones), leaving them unaffected. Global Warp installs are remapped from `~/.warp/` (Warp internal state) to `~` so all global installs share a consistent cwd.
- In `TemplatableMCPServerManager::spawn_server_impl`, default `cli_server.cwd_parameter` from this helper when unset. Single funnel — covers both auto-spawn and the manual UI opt-in path. User-supplied `working_directory` always wins.
- ENOENT-aware logging at the spawn site: when `TokioChildProcess::spawn()` fails with `NotFound`, the MCP log file now spells out the server name, the missing executable, the cwd we used, and a hint pointing the user at `working_directory`. The user-surfaced error string is unchanged.
- Documented the new defaulting behavior and `working_directory` override in `resources/bundled/skills/add-mcp-server/SKILL.md`.
## Testing
Verified spawn-site behavior manually. Demo [here](https://www.loom.com/share/ec01d98ae9114433b8ae87f5f17adfd4)!
- Added `test_parse_cli_server_preserves_explicit_working_directory` in `mod_test.rs` to lock in that an explicitly-set `working_directory` round-trips through parsing and won't be clobbered by the new defaulting logic.
- Skipped a unit test for the new helper itself — it's a thin lookup over `file_based_servers_by_root` and the sorted-pick policy is straightforward enough to validate manually.
- Spawn-site behavior (cwd actually applied, ENOENT log emission) verified manually against a `pnpm`\-based repro.

## Changelog Entries for Stable
CHANGELOG-BUG-FIX: Project-scoped file-based MCP servers now spawn from the repo root by default (and global ones from `~`), so configs with relative commands/args (and workspace launchers like `pnpm`/`npm`) work without an explicit `working_directory`.
## Description
Moves the "Discard all" menu item to the last position in
`header_menu_items_new`, so it appears after the AI context and comment
items. This matches the intended UX ordering from
[WAR-7381](https://linear.app/warpdotdev/issue/WAR-7381/discard-all-should-be-the-last-item-in-the-list).
## Testing
Manually verified the ordering logic. No new tests needed — this is a
pure reordering of existing menu items with no behavioral changes.

## Description
Adds contextual tooltips to disabled git operation buttons so users
understand why they can't click them. Tooltips are intentionally limited
to **disabled states only** — enabled buttons don't get tooltips since
their labels are self-explanatory.
**Changes:**
- Code review header: "No changes to commit" on the disabled Commit
button; "No git actions available" on the disabled chevron
- Commit dialog: "Enter a commit message" on the disabled Confirm button
(only shown once file changes have loaded — silent during the async load
window)
- Bug fix: the PR #N button in the header was staying greyed out after
transitioning from a disabled Commit mode, because `ViewPr` mode never
called `set_disabled(false)`

## Testing
Manually verified:
- Commit button with no changes shows "No changes to commit" on hover
- Chevron with no changes shows "No git actions available" on hover
- Commit dialog Confirm button shows "Enter a commit message" once files
load but message is empty; no tooltip shown during async load
- PR #N button is no longer greyed out after committing all changes
No new automated tests added — these are tooltip strings on existing
button state logic that is already exercised by existing tests.

## Description
A couple issues that needed fixing:
* Using `--all-features` and `--all-targets` causes us to try to build
the first-party binaries with embedded configuration, which isn't
available from this repository. To unblock CI, we'll only run clippy on
the default feature set for right now.
* Similarly, testing compilation with release configuration was trying
to build the `dev` channel; this switches that over to the `oss`
channel.
## Description
The local `Review Pull Request` workflow in this repo has been failing
on every `pull_request_target` event with `startup_failure` (no jobs
created) for newly opened PRs. Recent runs that hit this:
- https://github.com/warpdotdev/warp/actions/runs/25059789050
- https://github.com/warpdotdev/warp/actions/runs/25059784082
- https://github.com/warpdotdev/warp/actions/runs/25059568488
### Root cause
`.github/workflows/review-pull-request.yml` declares a `focus` input on
its own `workflow_call` interface and forwards it to the upstream
reusable workflow at
`warpdotdev/oz-for-oss/.github/workflows/review-pull-request.yml@main`.
That upstream workflow's `workflow_call` interface no longer declares
`focus` — it was removed in oz-for-oss commit
[`757b052`](https://github.com/warpdotdev/oz-for-oss/commit/757b052) (PR
#393, "feat(review): allow non-collaborator /oz-review and cap at 3 per
PR"). When the local job tries to forward `focus:` in its `with:` block,
GitHub fails workflow validation before any job is created, which
surfaces as `startup_failure`.
### What this PR changes
Drops every reference to `focus` from the local caller so the contract
matches the upstream `workflow_call` again:
- Removes the `focus` input from `workflow_call.inputs`
- Removes `INPUT_FOCUS` from the `resolve` step's `env`
- Removes the `focus = os.environ.get("INPUT_FOCUS", "")` read and the
heredoc-style `focus<<__EOF__` write to `GITHUB_OUTPUT`
- Removes `focus` from the `resolve` job's `outputs:`
- Removes `focus: ${{ needs.resolve.outputs.focus }}` from the
`review_pr` reusable-workflow `with:`
The forwarded inputs are now `pr_number`, `trigger_source`, `requester`,
and `comment_id`, matching the upstream interface.
### Note on `enforce-pr-issue-state.yml`
While debugging, I confirmed `enforce-pr-issue-state.yml` is
`workflow_call`-only and is not invoked anywhere in this repo (it has
zero historical runs), unlike in `oz-for-oss` where `pr-hooks.yml`
orchestrates enforcement before reviews. That gap is independent of this
fix — `review-pull-request.yml` here listens directly to
`pull_request_target` and does not depend on enforcement output. If we
want enforcement to gate PR reviews on this repo too, that's a follow-up
(either add a `pr-hooks.yml` orchestrator or wire
`enforce-pr-issue-state.yml` to listen to `pull_request_target` directly
and have `review-pull-request.yml` `needs:` it).
## Testing
- `python3 -c "import yaml; yaml.safe_load(...)"` on the modified
workflow to confirm the YAML still parses.
- Diff-checked that the local `with:` block matches the inputs declared
by the upstream `workflow_call` at
`warpdotdev/oz-for-oss/.github/workflows/review-pull-request.yml@main`.
- After this merges, the next `pull_request_target` event on a non-draft
PR should produce a `Review Pull Request` run that actually creates the
`resolve` and `review_pr` jobs instead of failing at startup.

## Description
The reusable workflows under
[`warpdotdev/oz-for-oss`](https://github.com/warpdotdev/oz-for-oss/tree/main/.github/workflows)
declare their Warp API key secret as `OSS_WARP_API_KEY`, but the local
caller workflows in this repo were forwarding it as `WARP_API_KEY`.
Because the name being passed didn't match the name declared by
`workflow_call`, the required secret was effectively missing and an
undeclared secret was being passed instead, which caused
`startup_failure` on every invocation.
Example failure:
https://github.com/warpdotdev/warp/actions/runs/25058665906 (Triage New
Issues (Local), `startup_failure`).
This PR renames the forwarded secret to `OSS_WARP_API_KEY:` in all local
adapter workflows so the names match what the reusable workflows
declare. The underlying secret value is still pulled from
`secrets.OSS_WARP_API_KEY` in this repo, so no repo secret changes are
needed.
Affected workflows:
- `.github/workflows/create-implementation-from-issue-local.yml`
- `.github/workflows/create-spec-from-issue-local.yml`
- `.github/workflows/enforce-pr-issue-state.yml`
- `.github/workflows/respond-to-pr-comment-local.yml`
- `.github/workflows/respond-to-triaged-issue-comment-local.yml`
- `.github/workflows/review-pull-request.yml`
- `.github/workflows/triage-new-issues-local.yml`
- `.github/workflows/trigger-implementation-on-plan-approved-local.yml`
- `.github/workflows/update-dedupe-local.yml`
- `.github/workflows/update-pr-review-local.yml`
- `.github/workflows/update-triage-local.yml`
- `.github/workflows/verify-pr-comment-local.yml`
## Testing
Manual review of the rename. After merge, re-run the failing `Triage New
Issues (Local)` workflow to confirm it no longer hits `startup_failure`
due to a missing required secret.
