Bmad Sprint Run

BMad Sprint Runner

Autonomously execute ALL stories in ALL epics in the current sprint. Runs as a single continuous loop: no pauses between stories, no confirmation prompts, no stopping until every story reaches done or blocked.

Execution Rule

After completing ANY action (story done, story blocked, retry exhausted, story created), immediately begin the next story by returning to STEP 0. The only valid exit is STEP 7 (all stories resolved). Every other step unconditionally transitions to another step. Never ask for permission to continue.

Story State Machine

Valid story statuses: backlog | ready-for-dev | in-progress | review | done | blocked

backlog --[create-story]--> ready-for-dev
ready-for-dev --[checkpoint]--> in-progress
in-progress --[dev-story]--> review
review --[quality gate pass + review pass]--> done
review --[quality gate fail]--> in-progress (retry)
review --[retry exhausted]--> blocked
review --[decision_needed]--> blocked
ANY --[infrastructure fail]--> STOP (not blocked, sprint halts)

Invalid transitions (MUST NOT occur):

• backlog -> anything other than ready-for-dev
• done -> anything (terminal state)
• blocked -> anything (terminal state for this sprint run)
• Skipping in-progress (every dev cycle must checkpoint first)

Forbidden Actions

State Safety

• FORBIDDEN: Mark a story done unless quality gates pass AND code review reports zero critical findings
• FORBIDDEN: Skip the quality gate (typecheck + tests) after dev-story
• FORBIDDEN: Skip code review after quality gate pass
• FORBIDDEN: Proceed past a failing quality gate or failing code review
• FORBIDDEN: Modify story content outside of skill invocations, EXCEPT status transitions to blocked, ready-for-dev, or in-progress
• FORBIDDEN: Invent review findings. If the review section is absent from the story file, treat as failure
• FORBIDDEN: Transition a story out of done or blocked

Git Safety

• FORBIDDEN: Use git stash (removes untracked bmad artifacts)
• FORBIDDEN: Push to remote (local state only)
• FORBIDDEN: Run on branch main or master
• FORBIDDEN: Skip recording the checkpoint hash before dev-story invocation
• FORBIDDEN: Run git reset --hard, git checkout -- , git restore, or git clean — these destroy committed or working-tree work. A false-failing quality gate once used git reset --hard to wipe a completed story
• FORBIDDEN: Run rm against the project to "clean up" — failed stories retry by fixing forward, never by deleting
• FORBIDDEN: Use git add -A, git add ., or any bulk-staging form. Enumerate changed files with git status --porcelain and stage each one by explicit path (git add path/to/file)
• FORBIDDEN: Defer work into one large commit. Commit in small, frequent increments — bmad-dev-story commits per logical chunk as it works, each story finalizes at its own STEP 5g, and STEP 7 only sweeps residual state files. Never batch multiple chunks or stories into a single large commit

Execution Flow

• FORBIDDEN: Stop between stories
• FORBIDDEN: Ask "Should I continue?" or "Ready for the next story?"
• FORBIDDEN: Print a summary and wait for user input mid-sprint
• FORBIDDEN: Run stories in parallel (strictly sequential)
• FORBIDDEN: Skip a story without marking it blocked with a reason
• FORBIDDEN: Assume in-memory state is current - always re-read from disk at STEP 0

Communication

• FORBIDDEN: Use second-person language in output ("you should", "I recommend you")
• FORBIDDEN: Print verbose explanations between steps - one-line status updates only
• FORBIDDEN: Stop execution to explain what the runner is about to do

Configuration

Fixed values. Do not change unless the user explicitly requests it.

Prerequisites

Before entering the loop, verify:

1. SPRINT_STATUS_PATH exists. If missing, instruct user to run /bmad-sprint-planning and stop.
2. At least one story is not done. If all done, go to STEP 7.
3. Current branch is not main or master. If on main, instruct user to create a feature branch and stop.
4. No other sprint-runner instance is active. Perform the advisory .sprint-runner.lock check — exact procedure in references/orchestration-steps.md STEP 0. This is advisory only: sprint-runner.py enforces a kernel-level fcntl.flock that the skill cannot hold across tool calls.

Each step below is a summary. Full procedures — exact commands, sub-steps, error conditions — are in references/orchestration-steps.md.

STEP 0: Initialize

Re-read SPRINT_STATUS_PATH, RUNNER_STATE_PATH, and DIGEST_PATH from disk with the Read tool — never trust cached values. Create RUNNER_STATE_PATH and DIGEST_PATH if absent. Discover project workspaces (typecheck/test/infra commands) from CLAUDE.md, falling back to build-manifest scanning. Print one-line status: "Sprint: [N] done, [M] remaining, [K] blocked. Next story."

STEP 1: Resolve Next Action

Read development_status from SPRINT_STATUS_PATH and pick the next story by priority in-progress -> review -> ready-for-dev -> backlog, lowest (epic, story) number first. Map to action: backlog -> create_story; ready-for-dev/in-progress -> preflight; review -> quality_gate; none left -> sprint_complete (STEP 7). For review stories, verify the Dev Agent Record exists — if missing, reset to ready-for-dev and re-resolve. Record the chosen story as current_story in RUNNER_STATE_PATH.

STEP 2: Create Story

Invoke Skill(skill: "bmad-create-story"). Verify a story file appeared in STORY_DIR and status is now ready-for-dev. Transition to STEP 3.

STEP 3: Pre-Flight Check

Check infrastructure (runtime deps, toolchains, local validators) for the workspaces the story touches. On failure: print what needs starting, transition to STEP 7 (infrastructure-blocked) — do not retry. On pass: transition to STEP 4.

STEP 4: Snapshot and Dispatch

Record current HEAD (git rev-parse --verify HEAD) as checkpoint_hash in RUNNER_STATE_PATH — a diff marker only, not a commit; the bmad skills create all commits. Inject digest + story context, then invoke Skill(skill: "bmad-dev-story"). Verify status is review. Transition to STEP 5.

STEP 5: Quality Gate

Diff against checkpoint_hash to find affected workspaces (files matching no workspace -> run ALL checks). Run typecheck then tests per workspace; on failure reset the story to in-progress and transition to STEP 6. Invoke Skill(skill: "bmad-code-review") and verify a findings section exists (missing = failure -> STEP 6). Route on findings:

• any critical -> STEP 6
• any decision_needed, zero critical -> mark blocked, STEP 0
• zero critical and zero decision_needed -> pass

On pass: write a digest entry (prune beyond DIGEST_SIZE), run the full-suite epic-boundary gate if the epic is complete, update RUNNER_STATE_PATH, stage each changed file by explicit path (see Git Safety) and commit story [ID]: completed, transition to STEP 0.

STEP 6: Retry Handler

Increment retry_count. If retry_count >= RETRY_BUDGET: mark the story blocked, append the reason to stories_blocked, transition to STEP 0. Never roll back — every commit the story produced stays on the branch for a human to inspect or salvage. If retries remain, fix forward on top of existing commits with the prior failure injected into the prompt: attempt 1 = re-invoke dev-story (STEP 4), attempt 2 = bmad-quick-dev with failure context (STEP 5), attempt 3 = dev-story with injected failure history (STEP 4).

STEP 7: Finalize

Print the sprint summary. Each story's work was already committed at its own STEP 5g, so only residual files (digest, runner state) remain — stage those by explicit path and commit sprint-run: [N] completed, [M] blocked. List blocked stories needing manual intervention, and suggest /bmad-retrospective per epic. STOP — the only valid termination point.
