[Extension]: Update of Spec Kit Schedule

[jfranc38]

Extension ID

schedule

Extension Name

Spec Kit Schedule — parallel subagent rounds

Version

0.7.4

Description

This is an update to an existing entry (schedule, currently listed at 0.6.2).

Zero-config planner that turns tasks.md into optimal parallel rounds for subagents (CP-SAT, critical-path aware, file-conflict safe) and runs them round by round.

Changed since 0.6.2: no configuration file is required any more (three identical subagent lanes by default); the plan is executed by a new speckit.schedule.implement command with the assistant's own subagents; commands reduced from 5 to 3 (portfolio, visualize, calibrate retired); parser aligned with the tasks.md that Spec Kit 0.16+ generates. See the changelog for 0.7.0–0.7.4.

This issue follows the release workflow in the publishing guide.

Key Features

• Zero configuration: /speckit.schedule.run plans the feature's tasks.md into parallel rounds for N identical subagents (default 3); optional two-knob config (workers, max_tasks_per_worker)
• Optimal assignment with CP-SAT: precedence from phases, [P] markers, same-file conflicts, tests-before-implementation and (depends on T###) notes; critical path and honest speedup reported
• Execution rounds: barrier batches sized for a subagent orchestrator, with a self-contained brief per lane (ordered tasks, files, forbidden files, DONE/FAILED/TOUCHED report format)
• /speckit.schedule.implement runs the rounds with the assistant's own subagents; progress lives only in the [x] checkboxes of tasks.md, so it is resumable at any point
• /speckit.schedule.status self-diagnoses the installation; hooks after tasks and converge offer to (re)plan
• Advanced portfolio (heterogeneous agents, skills, context budgets, cost-aware objective) still available through an agents: block

Testing Checklist

• Extension installs successfully via download URL
• All commands execute without errors
• Documentation is complete and accurate
• No security vulnerabilities identified
• Tested on at least one real project

Submission Requirements

• Valid extension.yml manifest included
• README.md with installation and usage instructions
• LICENSE file included
• GitHub release created with version tag
• All command files exist and are properly formatted
• Extension ID follows naming conventions (lowercase-with-hyphens)

Testing Details

Tested on:

• macOS 15 (arm64) with Spec Kit v0.16.4 and v1.0.4
• CI: Ubuntu with Python 3.10, 3.11 and 3.12 (729 tests, 93% coverage, smoke and packaging checks)

Test project: fresh specify init --here --integration claude, then specify extension add schedule --from <download URL>; also a spec-kit 0.16 feature with a 25-task tasks.md.

Test scenarios:

1. Install from the download URL: 5 skills registered (speckit-schedule-run, -implement, -status plus the plan/solve aliases), 2 hooks written to .specify/extensions.yml, schedule-config.yml scaffolded.
2. /speckit-schedule-run: first run bootstraps the private Python environment (~40 s), then plans 25 tasks into 6 rounds × 3 workers with a 2.2× speedup; schedule.md and schedule.json written.
3. /speckit-schedule-implement loop driven by the CLI (next → subagents → mark) to DONE; stale plans rejected; blocked lanes reported.
4. /speckit-schedule-status reports healthy after the first run.
5. Re-install with --force preserves an edited schedule-config.yml.

Example Usage

# Install extension
specify extension add schedule --from https://github.com/jfranc38/spec-kit-schedule/archive/refs/tags/v0.7.4.zip

# After /speckit-tasks has produced tasks.md for the feature:
/speckit-schedule-run          # rounds × workers, speedup, critical path → schedule.md + schedule.json
/speckit-schedule-implement    # one subagent per lane per round; progress in tasks.md checkboxes
/speckit-schedule-status       # self-diagnosis

Additional Context

Update of the existing schedule entry. Kept from the current entry: created_at, downloads, stars, category, effect, verified. Changed: name, description, version, download URL, documentation link (the repository's default branch is master), command/hook counts and tags.

Release notes: https://github.com/jfranc38/spec-kit-schedule/blob/master/CHANGELOG.md (0.7.0 zero-config + implement command; 0.7.1–0.7.4 fixes found by a refinement pass, including the zip install losing the executable bit on the wrapper).
