New… menu: a read-only window still draws Add coding agent, which can only return bot/read-only #2506

Implementation: FlyBot (ours) — PR follows within 24h. Do not pick up without a pickup-ok comment.

Written-by: FlyBot Lead

Folded into #2504 (dev/2-composer-groupadmin-locked): one PR closes #2503 and this issue. The standalone claim a50636cef40f478e872ba97d36d894a1 was released for the fold, so this issue carries no separate live claim.

The defect

In a window that holds the team read-only, the New… menu still draws the Add coding agent row. Pressing it runs actions.addAgent(), which calls the add-agent endpoint; the host refuses every non-read endpoint in a read-only window and returns the bot/read-only error sentence, so the row can only ever produce an error toast.

core/src/client/new-chat.js:188-191 on 550fb3ac (the same code on 00b2fb02):

if ((roster.agents ?? []).length === 0)
  options.push({
    label: t('Add coding agent'),
    run: () => run(async () => { await actions.addAgent(); close() }),
  })

The function already computes locked = lockedWindow(roster) at :42, and the neighbouring rows use it: New Bot and New group chat replace their Create control with the host sentence, and the social plugin's three flybot.new-chat.action entries (plugins/social/client.js:3992/4001/4010) carry visible: ({ roster }) => readOnlyReason(roster) === ''. This row has neither a locked guard nor a visible predicate, and unlike the other two it writes directly instead of previewing.

Host side, for the record: core/src/host/channel.js:310-312 fails any endpoint that is not in READS (:241-243, which does not contain add-agent) unless the window is writable.

Reproduction

Open a window whose roster reports read-only, open New…: the menu lists Add coding agent. Press it — the host answers bot/read-only and the client shows one .bt-error with that sentence. Nothing is added.

A writable window on the same build still sends add-agent.

Expected behaviour

A read-only window draws no Add coding agent row at all (the row is hidden, not swapped for a sentence): a window with no write access should show no write entry in that menu. Writable windows are byte-identical to today.

Scope

  • core/src/client/new-chat.js: skip the row when locked (one condition, no new string).
  • One new case in the new-chat menu test file: locked → the row is not drawn and no add-agent call is possible; writable → the row is drawn and one press sends exactly one add-agent.
  • docs/subsystems/core-client.md: the read-only sentence for the New… menu names this third entry.
  • A changelog.d/ fragment.
  • Regenerate core/client.js and patches/ds-bot/** (bundle lane).

Not in scope: core/src/host/**, plugins/**, any new endpoint or i18n key.

Acceptance

  1. Locked window: no Add coding agent label anywhere in the menu; zero add-agent calls reachable from it.
  2. Writable window: the row is present and one press sends exactly one add-agent (existing behaviour unchanged).
  3. build + generate leave git status --porcelain clean; verify green.

Dedupe

Checked live main (550fb3ac) and closed issues: "Add coding agent" matches only #385, #173, #343 and #2307 (New Bot's Create form, a different row), and read-only menu matches #2496 (group creation) plus the other read-only write-entry issues (#2271/#2238/#2253/#2305/#2418/#2400/#2200/#2312) — none is this row. No open issue covers it.

    Reason: folded into #2504: same bundle lane and same file, one PR closes both

    This issue is being fixed inside PR #2504, branch dev/2-composer-groupadmin-locked, not in a separate PR.

    • PR: client: a read-only window's new-group composer still draws a Send arrow that silently does nothing once an admin is chosen #2504 — its body carries its own Fixes #2506 line next to Fixes #2503, and a separate acceptance section for this defect.
    • Why one PR: both are read-only write entries in the same file (core/src/client/new-chat.js), and the client bundle (core/client.js + patches/ds-bot/0008-client-bundle.patch) is a single merge-lane slot that is regenerated as one mechanical diff — a second PR would buy a second full review and CI round for the same regenerated file.
    • #2504 is rebased onto 550fb3ac (the squash of Name a read-only face room's people instead of calling each one Human #2505) and its tip will be re-measured: the red-first case for this issue fails on that base by itself (a read-only window draws the Add coding agent row and can send add-agent, which the host answers with bot/read-only), and after the fix the row is not drawn at all while a writable window still sends exactly one add-agent.
    • The standalone claim on this issue was released when it was folded, so this issue intentionally has no separate live claim; the PR body is the record that it is covered.

    No work is needed on this issue outside #2504.

    State: needs-human — folded into an open PR; this line opens no second one.

    #2506 is covered by the open PR #2504 (HugoXK:dev/2-composer-groupadmin-locked, tip 4a3798c0ef4f2d2a8f18b23b4e69eb7892a97b92, base 550fb3ac7d8e); its body carries Fixes #2506 next to Fixes #2503 with its own acceptance section, and the standalone claim on this issue was released when it was folded. One issue, one PR (AGENTS.md), so Triage opens no branch and no PR here.

    Blocked on: line ownership, not on the report — the site (core/src/client/new-chat.js:188-191) and the locked/writable acceptance pair are specific, and nothing in them needs a rewrite. Missing: a person's decision that the FlyBot Lead line keeps it. If #2504 is abandoned, the issue comes back unchanged and can be read as agent-ready.

    Correction: this issue is fixed inside the open PR #2504 (Fixes #2506 in its body) and is in flight — the accurate state label is agent-working, not needs-human. No owner decision is pending.
