Reliability & compatibility
Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

Sprint Kickoff
Purpose
Provides the user-facing "kick off the sprint" command. Performs a quick readiness check, creates the sprint branch, confirms with the user, then hands off to /sprint-deliver for autonomous delivery of all use cases.
Nexa Rules Gate
Read and follow ${CLAUDE_PLUGIN_ROOT}/shared/readiness/NEXA_RULES_GATE.md.
Flow
Step 1: Locate the Sprint
- Verify
docs/sprints/next-sprint/exists.
- If not, stop: "No active sprint found. Run
/sprint-prepareto start a sprint."
- Read
docs/sprints/next-sprint/readiness-report.md.
- If not found, stop: "Readiness report missing. Run
/sprint-preparefirst."
Step 2: Determine Sprint Number
- List existing sprint folders in
docs/sprints/:
- Pattern:
sprint-1/,sprint-2/, etc. - Find the highest number N
- New sprint number = N + 1
- If no numbered sprints exist, start with sprint-1
Step 3: Display Sprint Summary
Present a brief summary to the user:
- Sprint number (N)
- Sprint scope (which UCs, delivery order)
- Pre-delivery action status (done / pending)
- Any blockers or warnings
Step 4: Create the Sprint Branch
- Ensure the working tree is clean:
``bash git status --porcelain `` If there are uncommitted changes, ask the user to commit or stash them before proceeding.
- Verify local
mainis up-to-date with the remote:
``bash git fetch origin main git diff main..origin/main --stat ` If there are differences, stop: > **Local main is behind origin/main.** Sprint preparation artifacts may not be > on this branch. Run git pull origin main first, or verify that /sprint-prepare > was completed (Phase 9 commits and pushes all preparation artifacts to main`).
- Create and checkout the sprint branch from main:
``bash git checkout -b sprint- ``
- Push the branch to remote:
``bash git push -u origin sprint- ``
- Confirm the branch was created:
> Sprint branch sprint- created and pushed. > > All delivery work will happen on this branch. > At sprint completion, a PR will be created to merge into main.
Step 5: Confirm and Delegate
Ask user for confirmation to proceed with delivery:
> Ready to kick off Sprint N? > > - Branch: sprint- (checked out) > - Scope: [N use cases] > - Delivery order: [list UC IDs] > > Proceed with delivery?
If confirmed, invoke /sprint-deliver.
Relationship to /sprint-deliver
/sprint-kickoff is the interactive entry point — it summarizes, creates the branch, and confirms. /sprint-deliver is the autonomous engine — it executes the delivery pipeline.
Users can call either directly:
/sprint-kickoff— when starting a sprint (recommended)/sprint-deliver— when resuming or re-running without the branch creation / confirmation step
