add remote feature for perf optimize in agent flow

Dev Engineer Review

  • Added serial and parallel optimization-item execution.
  • Added isolated worktrees, batch integration, checkpoint recovery, and remote SSH/Slurm execution.
  • Added execution filesystem abstractions, path validation, artifact synchronization, GitOps helpers, and remote execution prompt contracts.
  • Updated workflow state to schema version 3 and exported new optimizer/evaluator and integrator stages.
  • Added fsspec and sshfs runtime dependencies.
  • Review focus: validate remote path safety, synchronization error handling, worktree cleanup, checkpoint compatibility, and consistency of serial and parallel execution.
  • Review focus: confirm configuration defaults and accepted values remain consistent across schemas, examples, CLI documentation, and prompts.

QA Engineer Review

  • Added or updated coverage in:
    • test_execution.py
    • test_gitops.py
    • test_progress.py
    • test_remote_execution_prompts.py
    • test_state.py
    • test_task_schema.py
    • test_workflow.py
  • Coverage includes remote filesystem routing, artifact synchronization, worktree lifecycle, progress persistence, prompt injection, schema validation, serial execution, parallel integration, checkpoint recovery, retry handling, cleanup, and baseline validation.
  • No tests/integration/test_lists/, test-db/, qa/, or waives.txt changes were identified in the provided change summary.
  • Test-list registration for the added and updated test functions requires follow-up.
  • Verdict: needs follow-up.

Review Change Stack

Walkthrough

The perf-optimize workflow now supports serial or parallel item batches, isolated Git worktrees, optional SSH-backed execution, an Integrator stage, shared progress history, and schema version 3 checkpoints.

Changes

Perf-optimize workflow

Layer / File(s) Summary
Execution modes and checkpoint contracts
agent-flow/agent_flow/workflows/perf_optimize/{state.py,task_schema.py,roadmap_schema.py}, agent-flow/agent_flow/workflows/perf_optimize/README.md, agent-flow/agent_flow/workflows/perf_optimize/cli.py, agent-flow/tests/workflows/perf_optimize/{test_state.py,test_task_schema.py}
The workflow defines serial and parallel item execution. Checkpoints store batch, integration, campaign branch, worktree, execution, and profile metadata.
Execution layout and isolated Git operations
agent-flow/agent_flow/workflows/perf_optimize/{execution.py,gitops.py,cli.py}, agent-flow/pyproject.toml, agent-flow/tests/workflows/perf_optimize/{test_execution.py,test_gitops.py}
Local and SSH-backed filesystem routing, selective artifact synchronization, linked worktrees, branch operations, and binary-safe patches are implemented and tested.
Integrator prompts and shared progress
agent-flow/agent_flow/workflows/perf_optimize/progress.py, agent-flow/agent_flow/workflows/perf_optimize/prompts/*, agent-flow/tests/workflows/perf_optimize/{test_progress.py,test_remote_execution_prompts.py}
The Integrator role and remote execution context are added. Shared progress writes use locking and step allocation. Integrator verdicts record candidate decisions and measurements.
Batch orchestration and workflow validation
agent-flow/tests/workflows/perf_optimize/test_workflow.py
Workflow tests cover isolated candidates, parallel integration, serial execution, resumable batches, profile gates, remote routing, cleanup, and updated agent wiring.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟠 High · up to c1c69

This change enables remote workers and artifact synchronization for performance optimization, but current behavior can reuse stale remote workspaces, accept incomplete results, redirect operations through colliding context names, or fail Git authentication with custom host-key settings. Because these issues can produce incorrect optimization decisions or prevent workflows from completing, the PR is not merge-ready until the remote workspace and synchronization safeguards are addressed.

Propagate the configured known-hosts file to remote Git commands.

When remote mode uses a custom --ssh-known-hosts file, RunFileSystems.from_layout() gives it to SSHFileSystem, but _git() invokes native ssh with only _SSH_OPTS. Native SSH therefore uses its default host-key files, so Git operations can fail host-key verification. Pass the path to gitops and add UserKnownHostsFile with StrictHostKeyChecking=yes.

Update the FakeGitOps docstring for the new worktree_clean result.

worktree_clean now returns True for a repository path whose last segment is integration. The class docstring at lines 70-71 still states that it always returns False. Fix the docstring so the integration worktree behavior is documented.

Also prefer Path(repo).name over str(repo).split("/")[-1] so the check does not depend on the path separator.

Add description fields to the integrator schema properties.

Every other append tool in this module documents each property (see the evaluator schema at lines 416-457). The integrator schema carries only types, so the agent must guess what required_gain_pct, best_candidate_id, remediation_attempts, and the item-id lists mean. This tool records the authoritative verdict the orchestrator branches on, so the field semantics matter most here.

Enforce the global_path/global_lock invariant.

When global_path is set without global_lock, _append_for_context performs an unsynchronized read-modify-write, so concurrent contexts may overwrite entries. Validate that global_path requires a shared global_lock; a per-context default lock is insufficient for multiple contexts using the same file.

Make the step assertion discriminate global allocation.

The global file is empty and current_step is 1, so the allocated global step and the local ctx.current_step both equal 1. The assertion passes under either semantic. Seed one entry into the global file first; then the global step becomes 2 while the local entry keeps step 1, which pins the routing behavior added in _append_for_context.

Define a precise checkpoint type for execution.

load_state() stores decoded execution data as dict[str, Any] without schema validation. Later, _configure_execution() passes it to ExecutionLayout.from_dict(), which expects the execution-layout fields and can reject malformed data. Use a precise serialized type and validate it before constructing WorkflowState.

Reject location names that shadow fixed context fields.

Line 104 accepts execution_campaign_repo, execution_task_path, and other fixed names because they have a valid prefix. Line 124 expands locations after the fixed fields, so the rendered context replaces the canonical path with the supplied value. This can direct remote Git, build, or benchmark operations to the wrong checkout.

Reject all fixed control_* and execution_* field names in locations. Add a collision test for each reserved namespace.

optimize stage (round 1's analyzer then plans without profiling).

Validate each item_batch entry before loading the checkpoint.

A batch-stage checkpoint with item_batch: ["invalid"] passes this check. PerfOptimizeWorkflow later indexes each entry with fields such as item_index and current_item_id, so --clean or resume can fail with TypeError or KeyError instead of rejecting the inconsistent checkpoint. Validate entry mappings and their required fields here.

Close the first workflow before rebinding workflow.

Line 3144 creates a workflow and line 3171 replaces it. The finally block at line 3176 closes only the second instance, so the first instance's agent layers are never closed. Call workflow.close() before the rebind.
