📝 Walkthrough

Summary by CodeRabbit

  • New Features

    • Unified the execute tool to support regular turn execution and durable workflow execution.
    • Durable executions now report queued status, run IDs, execution metadata, and clear failure outcomes.
    • Tool guidance and terminal summaries distinguish regular and durable execution modes.
  • Bug Fixes

    • Improved workflow tracking for successful durable executions, including cancellation, validation, and duplicate-event handling.
    • Improved tool-schema refresh behavior when durable execution becomes available.

Walkthrough

The execute tool now supports turn and durable profiles. Durable requests submit workflows with session ownership and return run IDs. Standalone workflow registration was removed. Schema caching and terminal tracking now use unified durable execution metadata.

Changes

Unified execute execution

Layer / File(s) Summary
Execute durable submission
internal/assistant/execute_tool.go, internal/assistant/tool_registry.go, internal/assistant/workflow_tool.go, internal/assistant/*workflow*_test.go, internal/assistant/execute_request_internal_test.go
The execute tool accepts durable requests, submits workflow runs, returns run IDs, and reports unavailable or failed submissions. Standalone workflow execution and registration were removed.
Provider-visible tool schema cache
internal/assistant/tool_schema_cache.go, internal/assistant/tool_schema_cache_internal_test.go
Cache keys now include complete tool definitions. Tests verify that durable execute availability changes the key.
Terminal durable-run tracking
internal/terminal/agent_tasks.go, internal/terminal/async_events.go, internal/terminal/workflow_submission.go, internal/terminal/tool_display.go, internal/terminal/*workflow*_test.go
Terminal tracking accepts validated durable MVM results from execute events, refreshes workflow state, deduplicates runs, and displays durable execution summaries.

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

Merge Risk: 🔵 Low · up to 5fa68

This PR unifies the programmable execution facade, but the benchmark baseline documentation does not define a comparable pre-unification contract, so performance comparisons may be misleading. The change is mergeable with explicit owner follow-up to correct the baseline.

Poem

I’m a rabbit with a durable queue,
Execute now knows what workflows do.
Run IDs hop from tool to screen,
Cache keys show the tools seen.
Turn and durable paths both grow—
Whiskers cheer the unified flow!

- Around line 31-33: Update docs/benchmarks/unified-mvm-phase-0-baseline.md
lines 31-33 to use the legacy model-facing workflow surface for durable baseline
runs. Update docs/benchmarks/unified-mvm-phase-0-tasks.json lines 17-45 so
durable task surfaces and prompts follow the legacy workflow contract, reserving
execute with durable profiling for post-unification comparisons.

In `@docs/release-notes.md`:
- Around line 11-15: Update the durable execute contract description to state
that name is optional, while retaining its role as a concise display name when
provided. Document the service’s fallback behavior for deriving a name when name
is omitted, using the existing execute-related naming behavior or symbol rather
than inventing a new rule.

- Around line 61-67: Update Execute’s prompt and profile schema generation to
use the same executor.submitter availability check: when it is nil, advertise
and permit only the turn profile; when present, include the durable description,
guidelines, and schema option. Keep durable execution validation consistent with
these exposed options.
