Closes #208

agentsVisible gated the composer's agent picker on hasCustomAgent (any native === false agent) or the showCustomAgents setting. A server shipping only native agents — Amicode's plan-first posture after retiring its custom pulse-designer agent (harmoniqs/amicode#389) — left the picker entirely hidden, so read-only plan sessions had no visible escalation affordance to build.

Fix: the picker shows when there is an actual choice — a custom agent (unchanged upstream behavior) or more than one selectable agent. plan + build counts. Single-agent setups keep today's hidden behavior.

hasAgentChoice is a pure helper in local-agent.ts, tested in local-agent.test.ts (bun:test); local.tsx swaps the predicate. Full bun typecheck clean; the 4 pre-existing src/context unhandled errors reproduce on the base (verified via stash).

Summary by CodeRabbit

  • New Features

    • Improved agent selection visibility when multiple agents or custom agents are available.
    • Added support for clearer agent-choice behavior across native and custom configurations.
  • Bug Fixes

    • Corrected cases where agent selection could be hidden despite multiple available choices.
  • Chores

    • Added automated upstream synchronization and reporting for repository maintenance.

…patch)

Adds .github/workflows/upstream-sync.yml — scheduled Mondays 09:00 UTC
+ workflow_dispatch, fetches anomalyco/opencode dev, opens
notturno/merge-upstream-YYYY-MM-DD against local/amicode.

- Zero-conflict merges: commit + push + open PR (hitl) ready for CI
- Conflicted merges: abort markers, commit .upstream-sync/report.md
  with file list + policy, push + open PR for hand-merge

Keeps the fork (never drops amicode surfaces) — just pulls
mothership improvements automatically. Handles sst → anomalyco
rename, sets git identity (fixes harmoniqs/amico#322).

…n for current view parity

Keeps PR current with latest viewed UI fixes (context ring, starter chips, etc. are already on local/amicode) plus thinker-line clean (5f8afb4). No rebase — preserves merge trace per fork policy.
agentsVisible gated on hasCustomAgent — a server shipping only native
plan/build (Amicode's plan-first posture, amicode#389) had its picker
vanish, leaving read-only sessions no visible escalation affordance.
Rule now: custom agent OR more than one selectable agent. Single-agent
setups keep today's hidden behavior.

Review Change Stack

📝 Walkthrough

Walkthrough

The PR adds a weekly or manual upstream synchronization workflow with merge reporting and pull request creation. It also updates agent picker visibility for multiple native agents, single custom agents, and single-agent setups.

Changes

Upstream synchronization workflow

Layer / File(s) Summary
Sync setup and upstream preparation
.github/workflows/upstream-sync.yml
The workflow defines triggers, permissions, concurrency, checkout settings, upstream metadata collection, and dated sync-branch creation.
Merge handling and pull request publication
.github/workflows/upstream-sync.yml
The workflow supports dry runs, clean merges, conflict reports, branch pushes, and clean or conflict-handling pull requests.

Agent picker visibility

Layer / File(s) Summary
Agent choice predicate and local integration
packages/app/src/context/local-agent.ts, packages/app/src/context/local-agent.test.ts, packages/app/src/context/local.tsx
hasAgentChoice shows the picker for custom agents or multiple agents. Local visibility uses this predicate, with tests for native, custom, empty, and single-agent lists.

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

Merge Risk: 🟠 High · up to 5a3e9

The PR adds an upstream-sync workflow that interpolates a manually supplied branch or ref into shell commands; a crafted value could execute commands with the workflow’s write-capable token, so the PR is not merge-ready until that input is safely passed and validated. Retry runs may also fail when they reuse an existing branch name.

🔒 Security & Privacy | 🟠 Major | ⚡ Quick win

Do not expand inputs.upstream_ref directly in shell source.

A manually dispatched value can terminate the surrounding quotes and execute commands. The commands run with a token that can push branches and create pull requests. Put the value in a workflow env variable, validate it as an allowed branch name, and reference "$UPSTREAM_REF" in every shell command and heredoc. This also applies to the later direct expansions of inputs.upstream_ref.

Proposed fix
       - name: Add upstream and fetch
         id: upstream
+        env:
+          UPSTREAM_REF: ${{ inputs.upstream_ref || 'dev' }}
         run: |
           set -euo pipefail
+          git check-ref-format --branch "$UPSTREAM_REF" >/dev/null
           if git remote get-url upstream >/dev/null 2>&1; then
             git remote set-url upstream https://github.com/anomalyco/opencode.git
           else
             git remote add upstream https://github.com/anomalyco/opencode.git
           fi
-          git fetch upstream "${{ inputs.upstream_ref || 'dev' }}" --prune
-          SHA=$(git rev-parse "upstream/${{ inputs.upstream_ref || 'dev' }}")
+          git fetch upstream "$UPSTREAM_REF" --prune
+          SHA=$(git rev-parse "upstream/$UPSTREAM_REF")

Make retry branch names unique.

If a run is retried after it creates notturno/merge-upstream-<date>-<short_sha>, Line 73 selects that same name. Line 76 then fails because git checkout -b cannot create an existing branch. Add a run-specific suffix, or reuse the existing branch and PR deliberately.

Merged with typecheck red — verified pre-existing: the default branch (local/amicode) fails the same src/mcp/browser.ts errors (TS18046/TS7006). This PR's diff touches only local-agent.ts/local-agent.test.ts/local.tsx; local bun typecheck on the branch is clean.
