Complete Implementation (Quality Gates + Recursion)

You MUST validate that the implemented feature meets its goals and quality gates. If follow-up plans
are created, route them to backlog items first, then recurse only when the follow-up matches the
current scope and priority (see Recursive Follow-up Handling section).

$ARGUMENTS uv run "${CLAUDE_PLUGIN_ROOT}/sam_schema/cli.py" </sam_cli>

The references/recursive-follow-up-handling.md file loaded by this skill is a plain file, not
substituted — it shows bare SAM CLI subcommands and args only (e.g. backlog list --title "..."),
never the invocation prefix. Prepend the command in above to every one of them.

[!IMPORTANT]
When provided a process map or Mermaid diagram, treat it as the authoritative procedure. Execute steps in the exact order shown, including branches, decision points, and stop conditions.
A Mermaid process diagram is an executable instruction set. Follow it exactly as written: respect sequence, conditions, loops, parallel paths, and terminal states. Do not improvise, reorder, or skip steps. If any node is ambiguous or missing required detail, pause and ask a clarifying question before continuing.
When interacting with a user, report before acting the interpreted path you will follow from the diagram, then execute.

Input Format Detection

Parse $ARGUMENTS to determine the input type before proceeding. A plan address is an opaque
logical identifier returned by sam_plan; pass it through unchanged.

The following diagram is the authoritative procedure for Input Format Detection. Execute steps in the exact order shown, including branches, decision points, and stop conditions.

    Input["Read $ARGUMENTS"] --> Q2{"starts with '#'?"}
    Q2 -->|Yes| IssueHash["Strip '#' → issue_number<br>→ proceed to 'Resolve Issue'"]

---

Resolve Issue

Entered when input is #N, bare N, GitHub URL, or another work-item reference such as
bd-a3f8. Normalize it to the opaque {item_ref} used by the selected backend. Skip for plan
address input.

Step 1 -- Fetch issue data:

uv run "${CLAUDE_PLUGIN_ROOT}/sam_schema/cli.py" backlog view --selector "{item_ref}"

If the response contains an error key:

ERROR: Work item {item_ref} not found. Verify the reference and try again.

Stop.

Step 2 -- Check for linked plan:

Read the plan field from the response.

The following diagram is the authoritative procedure for Resolve Issue Step 2 linked plan check. Execute steps in the exact order shown, including branches, decision points, and stop conditions.

flowchart TD
    Plan{plan field<br>present and non-empty?}
    Plan -->|Yes| AutoResolve["Read opaque plan address from plan field<br>→ proceed to 'Resolve Plan Address'<br>(existing 7-phase flow)"]
    Plan -->|No| PropFlow["→ proceed to 'Proportional Quality Gates'"]

When auto-resolving to the SAM path, output:

Work item {item_ref} has linked plan: {plan_address}
Proceeding with full quality gates.

Step 3 -- Extract context for proportional gates:

From the backlog_view response, extract and store:

• item_ref: str (the response's opaque reference)
• title: str
• body: str (full issue body text)
• labels: list[str]
• issue_number: int or None (GitHub only; used solely for commit-history discovery)

These values are used by the Proportional Quality Gates section below.
Set {item_slug} to the lowercase {item_ref} with each non-alphanumeric run replaced by one hyphen.

---

Proportional Quality Gates

Entered only when the work item has no linked plan. Skip this section for plan-address input or when
the work item has a linked plan (auto-resolved to the SAM path).

Step 1 -- Discover modified files:

git log --all --grep="#${issue_number}" --format=%H

Run the commit search only when issue_number is present. For each commit SHA returned:

git diff-tree --no-commit-id --name-only -r {sha}

Deduplicate the file list. If no commits reference the issue number, fall back to:

git diff --name-only main...HEAD

Store the deduplicated file list as modified_files.

If modified_files is empty after both strategies:

WARNING: No modified files found for work item {item_ref}.
Code review and test verification will run against the full working tree.

Step 2 -- Extract acceptance criteria from issue body:

Parse the body field for an acceptance criteria section. Search for these markers (case-insensitive, in order):

1. ## Acceptance Criteria header -- extract all content until next ## header
2. **Acceptance Criteria**: bold marker -- extract all content until next bold marker or ## header
3. Lines starting with - [ ] (unchecked checkboxes) -- collect all such lines

Store as acceptance_criteria (string or None). If none found, set to None.

Step 3 -- Build proportional quality gate plan:

Create the SAM plan directly with 5 tasks. The documentation pass (T4 Documentation Drift Audit + T5 Documentation Update) is included on this direct/issue-only route exactly as it is on the full SAM path — a feature reached through proportional gates is held to the same documentation standard as one reached through a linked plan:

mcp__plugin_dh_sam__sam_plan(
    config={"action": "create",
            "slug": "pqg-{item_slug}",
            "goal": "Proportional quality gate verification for work item {item_ref}",
            "owner_reference": "{item_ref}",
            "tasks": [
                {"id": "T1", "title": "Code Review",        "agent": "code-reviewer",   "dependencies": [],    "priority": 1, "complexity": "medium",
                 "body": "Review files modified for work item {item_ref}: {modified_files}. Check against acceptance criteria: {acceptance_criteria}"},
                {"id": "T2", "title": "Test Verification",  "agent": "feature-verifier","dependencies": ["T1"],"priority": 1, "complexity": "medium",
                 "body": "Verify work item {item_ref} acceptance criteria are met. Files in scope: {modified_files}"},
                {"id": "T3", "title": "Acceptance Check",   "agent": "integration-checker","dependencies": ["T2"],"priority": 1, "complexity": "low",
                 "body": "Confirm acceptance criteria for work item {item_ref} pass end-to-end: {acceptance_criteria}"},
                {"id": "T4", "title": "Documentation Drift Audit", "agent": "doc-drift-auditor","dependencies": ["T3"],"priority": 1, "complexity": "low",
                 "body": "Audit documentation for drift introduced by work item {item_ref}. item_id={item_ref} (REQUIRED — register the audit-report artifact against it; block if absent). project_root is the repository root (your current working directory). Files in scope: {modified_files}. Report any docs that are now stale, missing, or contradicted by the change."},
                {"id": "T5", "title": "Documentation Update", "agent": "service-docs-maintainer","dependencies": ["T4"],"priority": 1, "complexity": "low",
                 "body": "Update documentation to resolve the drift found in T4 for work item {item_ref}. item_id={item_ref} (read the audit-report artifact registered against it). project_root is the repository root (your current working directory). Files in scope: {modified_files}."}
            ]}
)

The pqg- prefix (proportional quality gate) distinguishes this plan from full SAM gates. Store
the response's opaque plan_ref as {pqg_plan_address} and pass it unchanged throughout the
dispatch loop.

Step 4 -- SAM dispatch loop:

Use the same SAM Dispatch Loop as the existing 7-phase flow (see "SAM Dispatch Loop (Phases T0-T6)" section). The loop operates identically — 5 tasks instead of 7 is the only structural difference. The proportional plan omits T0 (Multi-Perspective Review) and T6 (Context Refinement) to stay proportional, but retains the T4/T5 documentation pass.

Phase-specific post-dispatch actions for proportional gates:

The following diagram is the authoritative procedure for Proportional Quality Gates phase-specific post-dispatch actions. Execute steps in the exact order shown, including branches, decision points, and stop conditions.

flowchart TD
    Done{Which task<br>just completed?}
    Done -->|"T1 Code Review"| T1Post["No follow-up extraction<br>(proportional gates do not<br>generate follow-ups)"]
    Done -->|"T2 Test Verification"| T2Post["Check test results in agent output<br>If failures: log but do not block<br>(completion gate handles pass/fail)"]
    Done -->|"T3 Acceptance Check"| T3Post["No post-dispatch action"]
    Done -->|"T4 Drift Audit"| T4Post{"Read the Total findings count<br>from T4's ARTIFACTS return block<br>(full report is in the audit-report artifact)"}
    T4Post -->|"0 findings — no drift"| SkipT5["sam_task(plan='{pqg_plan_address}', task='T5',<br>config={action:'state', status:'skipped'})"]
    T4Post -->|"1 or more findings — drift"| T5Ready["T5 remains NOT_STARTED — will be<br>dispatched on next loop iteration"]
    Done -->|"T5 Documentation Update"| T5Post["No post-dispatch action"]
    T1Post --> Continue["Continue loop"]
    T2Post --> Continue
    T3Post --> Continue
    SkipT5 --> Continue
    T5Ready --> Continue
    T5Post --> Continue

Detecting drift in T4 output: The @dh:doc-drift-auditor agent returns a Total findings: {count} line in its ARTIFACTS block and registers the full drift report as the audit-report artifact. No drift = Total findings: 0 → skip T5. Drift = Total findings of 1 or more → dispatch T5. If the count line is absent, read the audit-report artifact and treat a non-empty ## Findings by Category as drift. This is the same drift-detection rule the full SAM path applies to its T4 phase.

Step 5 -- Completion verification gate:

After the dispatch loop exits, verify all phases (defined by build_quality_gate_plan in sam_schema/core/quality_gates.py) reached terminal status:

uv run "${CLAUDE_PLUGIN_ROOT}/sam_schema/cli.py" plan status --plan-address "{pqg_plan_address}"

All 5 tasks must have status == 'complete', with one exception: T5 (Documentation Update) may have status == 'skipped' when T4 found no drift. Any other task with status == 'skipped' is an unauthorized skip — treat as a failure. This skip whitelist matches the full SAM path's Completion Verification Gate.

The following diagram is the authoritative procedure for Proportional Quality Gates completion verification. Execute steps in the exact order shown, including branches, decision points, and stop conditions.

flowchart TD
    Status["sam_plan(plan='{pqg_plan_address}', config={action:'status'})"] --> Iter["Iterate over all 5 tasks"]
    Iter --> Check{For each task:<br>check status}
    Check -->|"status == 'complete'"| PassTask["Task passes"]
    Check -->|"status == 'skipped' AND task_id == 'T5'"| PassTask
    Check -->|"status == 'skipped' AND task_id != 'T5'"| FailUnauth["FAIL — unauthorized skip"]
    Check -->|"any other status"| FailIncomplete["FAIL — task incomplete or blocked"]
    PassTask --> AllPassed{All 5 tasks<br>passed?}
    AllPassed -->|Yes| Proceed["Proceed to Step 6"]
    AllPassed -->|No| Stop["STOP — report failures, do NOT apply label"]
    FailUnauth --> AllPassed
    FailIncomplete --> AllPassed

On verification failure:

COMPLETION BLOCKED — Proportional Quality Gate Incomplete

Failed tasks:
  {task_id} ({phase_name}): status={status}
  [repeat for each failing task]

To resume: re-run /complete-implementation {item_ref}
BLOCKED tasks will be reset to NOT_STARTED automatically.

Stop. Do not apply the status:verified label.

Step 6 -- Apply status:verified label:

On verification success:

mcp__plugin_dh_backlog__backlog_update(selector="{item_ref}", verified=True)

Note — no CLI equivalent exists for verified=True as of 2026-08-05 (backlog item #2793): the
CLI's backlog update has no --verified flag. This call must stay MCP.

Beads backend: No dh:state:verified label — skip this call, continue.

On failure (GitHub only), output:

COMPLETION BLOCKED — status:verified label could not be applied.

Error: {error}
Work item: {item_ref}

Fix the error (check backend credentials and access), then re-run /complete-implementation {item_ref}.

Stop. Do not proceed to the Final Step commit.

Step 7 -- No recursive follow-up handling:

The issue-only path does not produce follow-up plans. Skip directly to "Final Step: Commit and Push Remaining Changes", then "Team Shutdown", then "Resolve the Issue".

---

Resolve Plan Address

Treat the supplied plan address as opaque. Pass the exact value to every sam_plan, sam_task,
CLI --plan-address, and skill invocation below. Read the plan once with
sam_plan(plan="{plan_address}", config={"action": "read"}); use its feature field as {slug}
and its issue field as {item_ref} when present. Do not derive either value from a path.

---

Pre-Phase 1: TN Verification Check

Before invoking Phase 1, check for a TN verification report produced by tn-verification-gate (which reads the T0 baseline written by t0-baseline-capture).

Use the {slug} and {item_ref} resolved from the plan. When {item_ref} is present, read the
TN-verification artifact via artifact_read(item_id={item_ref}, artifact_type="TN-verification").
When it is absent, proceed to Phase 1 because no artifact owner is addressable.

The artifact content contains a list of per-criterion BookendVerification records — one per
acceptance-criteria-structured entry. There is no top-level verdict field. Aggregate the verdict
by scanning all records: the overall result is FAIL if any record has status: regressed;
otherwise PASS.

The following diagram is the authoritative procedure for Pre-Phase 1 TN Verification Check. Execute steps in the exact order shown, including branches, decision points, and stop conditions.

flowchart TD
    Read["artifact_read(item_id={item_ref}, artifact_type='TN-verification')"] --> Exists{Artifact exists?}
    Exists -->|No| Proceed["No structured criteria — proceed to Phase 1"]
    Exists -->|Yes| Scan["Scan all per-criterion records<br>for status: regressed"]
    Scan --> AnyRegressed{Any criterion<br>has status: regressed?}
    AnyRegressed -->|No| Proceed
    AnyRegressed -->|Yes| Stop["STOP — report regressions and block completion"]
    Stop --> Report["Display each criterion with status: regressed<br>Show check_command, T0 stdout, TN stdout<br>Instruct: fix regressions before re-running"]

If any criterion has status: regressed:

1. List each criterion where status: regressed with its check_command, T0 captured stdout, and TN captured stdout.
2. Output:

COMPLETION BLOCKED — TN Verification Failed

Regressed criteria:
  {criterion-id}: {description}
    command: {check_command}
    T0 result: exit {code}, stdout: {stdout}
    TN result: exit {code}, stdout: {stdout}

Fix the regressions, then re-run /complete-implementation.

3. Stop. Do not proceed to Phase 1.

---

Pre-Phase 1a: Migration Fidelity Sign-Off

Before proceeding to Artifact Discovery, check for migration signals.

Execute the full gate procedure defined in ./references/migration-fidelity-gate.md.

Summary of detection signals (full evaluable criteria in the reference):

• Issue title or body contains: "migrat", "convert format", "replace .md", "format conversion", "move from", "transition from"
• Any task acceptance_criteria field contains: "delete", "remove source", "after migration complete", "drop the source"

If no signal found — skip gate, proceed to Artifact Discovery.

If signal found — confirm all four fidelity items from the reference before proceeding. If any unconfirmed, emit COMPLETION BLOCKED — Migration Fidelity Gate (format in reference) and stop.

---

Pre-Phase: Artifact Discovery

When {item_ref} is known, query its artifact manifest to discover all plan artifacts for this feature:

uv run "${CLAUDE_PLUGIN_ROOT}/sam_schema/cli.py" artifact list --item-id "{item_ref}"

If the response contains artifacts, pass the manifest and {item_ref} to quality gate agents
(Phases T0-T6) so they can retrieve content with artifact_read. If the manifest is empty, proceed
without optional artifacts. If the call errors, report the provider error and stop; artifact content
has no second high-level storage route.

---

Pre-Phase 1b: Process Accumulated Concerns

Execute the full procedure defined in ./references/concerns-processing.md.

Summary: Read backlog item → if ## Concerns has unchecked items, verify each (create backlog item if real; mark unconfirmed if not) → update section → proceed to Quality Gate Plan Creation. If no concerns section, proceed immediately.

---

Quality Gate Plan Creation

After the pre-phases complete, set up the SAM-enforced quality gate plan.

Use the {slug} resolved from the implementation plan's feature field.

Step 1: Check for existing QG plan

uv run "${CLAUDE_PLUGIN_ROOT}/sam_schema/cli.py" plan list --search "qg-{slug}"

The following diagram is the authoritative procedure for Quality Gate Plan Creation Step 1 check for existing QG plan. Execute steps in the exact order shown, including branches, decision points, and stop conditions.

flowchart TD
    List["sam_plan(config={action:'list', search:'qg-{slug}'})"] --> Found{QG plan found?}
    Found -->|No| Create["sam_plan(config={action:'create', ...})<br>tasks list from phase mapping table"]
    Found -->|Yes| Check{All tasks terminal?}
    Check -->|"Yes — COMPLETE or SKIPPED"| Skip["Skip to Completion Verification Gate"]
    Check -->|"No — tasks remain"| Reset["Reset BLOCKED tasks to NOT_STARTED,<br>resume SAM dispatch loop"]
    Create --> Loop["Enter SAM Dispatch Loop"]
    Reset --> Loop

When a QG plan is found, store that list entry's opaque plan_ref as {qg_plan_address}. Omit
owner_reference from the create call below only when {item_ref} is absent.

Step 2: Create QG plan (if not found)

If no QG plan exists, create it directly using the phase mapping table above:

mcp__plugin_dh_sam__sam_plan(
    config={"action": "create",
            "slug": "qg-{slug}",
            "goal": "Quality gate enforcement for {slug}",
            "owner_reference": "{item_ref}",
            "tasks": [
                {"id": "T0", "title": "Multi-Perspective Review", "agent": "task-worker",     "dependencies": [],           "priority": 1, "complexity": "high"},
                {"id": "T1", "title": "Code Review",              "agent": "code-reviewer",   "dependencies": [],           "priority": 1, "complexity": "medium"},
                {"id": "T2", "title": "Feature Verification",     "agent": "feature-verifier","dependencies": ["T1"],       "priority": 1, "complexity": "medium"},
                {"id": "T3", "title": "Integration Check",        "agent": "integration-checker","dependencies": ["T2"],   "priority": 1, "complexity": "medium"},
                {"id": "T4", "title": "Documentation Drift Audit","agent": "doc-drift-auditor","dependencies": ["T3"],     "priority": 1, "complexity": "low",
                 "body": "Audit documentation for drift in {slug} (work item {item_ref}). item_id={item_ref} (REQUIRED — register the audit-report artifact against it; block if absent). project_root is the repository root (your current working directory)."},
                {"id": "T5", "title": "Documentation Update",     "agent": "service-docs-maintainer","dependencies": ["T4"],"priority": 1, "complexity": "low",
                 "body": "Update documentation to resolve the drift found in T4 for {slug} (work item {item_ref}). item_id={item_ref} (read the audit-report artifact registered against it). project_root is the repository root (your current working directory)."},
                {"id": "T6", "title": "Context Refinement",       "agent": "context-refinement","dependencies": ["T5"],    "priority": 1, "complexity": "medium"}
            ]}
)

Store the response's opaque plan_ref as {qg_plan_address}. This is the only address used for
subsequent QG plan and task operations.

Step 3: Reset BLOCKED tasks (on re-run)

If the QG plan already exists and has BLOCKED tasks, reset each to NOT_STARTED before entering the dispatch loop:

For each task where status == "blocked":
    mcp__plugin_dh_sam__sam_task(
        plan="{qg_plan_address}",
        task="{task_id}",
        config={"action": "state", "status": "not-started"}
    )

This allows re-running complete-implementation to resume from the blocked phase without re-executing completed phases.

SAM Dispatch Loop (Phases T0-T6)

Phase task mapping:

Task	Phase	Agent
T0	Multi-Perspective Review	dh:multi-perspective-review (orchestrated)
T1	Code Review	code-reviewer
T2	Feature Verification	feature-verifier
T3	Integration Check	integration-checker
T4	Documentation Drift Audit	doc-drift-auditor
T5	Documentation Update	service-docs-maintainer
T6	Context Refinement	context-refinement

Team Setup

Check for an existing implementation team before dispatching QG agents:

• team_name = "impl-{slug}" (same team created by implement-feature)
• If the team exists (config at ~/.claude/teams/impl-{slug}/config.json), reuse it for QG agent dispatch
• If no team exists, create one: TeamCreate(team_name="impl-{slug}")
• Store team_name for use in agent dispatch and the Team Shutdown step below

Dispatch Loop

Repeat until sam_plan(plan="{qg_plan_address}", config={"action": "ready"}) returns a
ReadyTasksResult with an empty ready_tasks list:

1. Get next ready task:

uv run "${CLAUDE_PLUGIN_ROOT}/sam_schema/cli.py" plan ready --plan-address "{qg_plan_address}"

If the result is empty, exit the loop and proceed to Completion Verification Gate.

2. Load the start-task skill:

Skill(skill="start-task", args="{qg_plan_address} --task {task_id}")

Pass team_name="{team_name}" when spawning QG agents so they join the existing implementation team.

start-task claims the task and marks it COMPLETE on finish via the SubagentStop hook. Do not call
sam_task(plan="{qg_plan_address}", task="{task_id}", config={"action": "claim"}) in the
orchestrator before this step — claiming here causes a double-claim that causes start-task to
receive claimed: false and stop without executing the task body.

3. Phase-specific post-dispatch actions:

After each dispatched phase completes, run the phase-specific processing before querying
sam_plan(plan="{qg_plan_address}", config={"action": "ready"}) again:

The following diagram is the authoritative procedure for SAM Dispatch Loop phase-specific post-dispatch actions. Execute steps in the exact order shown, including branches, decision points, and stop conditions.

Completion Verification Gate

After the SAM dispatch loop exits, verify all phases reached terminal status before allowing label application.

uv run "${CLAUDE_PLUGIN_ROOT}/sam_schema/cli.py" plan status --plan-address "{qg_plan_address}"

The following diagram is the authoritative procedure for Completion Verification Gate. Execute steps in the exact order shown, including branches, decision points, and stop conditions.

    FailUnauth --> AllPassed
    FailIncomplete --> AllPassed
    FailBlocked --> AllPassed

Skip whitelist: ONLY T5 (Documentation Update) may have status: skipped. Any other task with status: skipped is an unauthorized skip — treat as a failure.

On verification failure, output:

COMPLETION BLOCKED — Quality Gate Incomplete

Failed tasks:
  {task_id} ({phase_name}): status={status}
  [repeat for each failing task]

To resume: re-run /complete-implementation {plan_address}
BLOCKED tasks will be reset to NOT_STARTED automatically.

Stop. Do not apply the status:verified label.

On verification success, proceed to Recursive Follow-up Handling.

Post-Phase-6: Surface Divergence Findings

If the T6 (Context Refinement) sub-agent output contained a DIVERGENCE_REQUIRING_REVIEW block (collected in the dispatch loop), include in the final output to the human:

Plan artifacts have intent divergences requiring your review.
See: [annotated artifact paths from agent output]
Divergences:
  [list from DIVERGENCE_REQUIRING_REVIEW block]

This is informational, not blocking. The human reviews at their discretion.
If absent, no additional output is needed — the feature proceeds normally.

---

Recursive Follow-up Handling

Constants

DH_RECURSIVE_REVIEW_TASK_DEPTH = 5

Maximum number of recursive review-implement-verify cycles permitted within a single
top-level /complete-implementation invocation. When {recursion_depth} reaches this
value, Guard 1 fires: all remaining in-scope follow-ups are routed to the backlog and
recursion stops.

Initialization: {recursion_depth} is set to 0 at skill invocation. It increments by 1
before each call to Skill(skill="implement-feature") in the recursion path. A re-run
of /complete-implementation on the same plan address starts {recursion_depth} at 0.

After all phases complete, route any follow-up plans created by Phase 1 (code-reviewer) to the
backlog before deciding on recursion. This ensures no follow-up plan is orphaned when the
orchestrator skips recursion.

Step 1: Detect Follow-up Plans

Retrieve the review report registered by @dh:code-reviewer during Phase 1:

uv run "${CLAUDE_PLUGIN_ROOT}/sam_schema/cli.py" artifact read --item-id "{item_ref}" --artifact-type "codebase-analysis"

If artifact_read returns an error, call
artifact_list(item_id={item_ref}, artifact_type="codebase-analysis"). If the manifest contains
an entry, report the provider read error and stop; registered content must remain readable through
the same provider boundary.

Check the verdict field in the report:

• PASS — no blocking findings; skip the entire routing section (no follow-ups to route)
• NEEDS-WORK or FAIL — extract the "Required changes (blocking)" section; each blocking
  item becomes a follow-up to route. When "Required changes (blocking)" is non-empty, run the
  fix loop first (max 3 cycles, {fix_cycle}=0): create one task per entry (agent: dh:task-worker)
  with sam_plan(config={"action": "create", "slug": "fix-{slug}-blocking-N", "goal": "Resolve blocking review findings", "tasks": [...], "owner_reference": "{item_ref}"}); store
  its returned plan_ref, dispatch via subagent_type="dh:task-worker", then reset T1 with
  sam_task(plan="{qg_plan_address}", task="T1", config={"action": "state", "status": "not-started"}) and re-dispatch T1. If verdict is PASS or blocking entries empty →
  proceed to Step 2; else fix_cycle += 1, repeat or BLOCKED at 3. On BLOCKED (exhausted
  or fix task blocked): report COMPLETION BLOCKED — Blocking Code Review Findings Not Resolved, do NOT route to backlog, stop, do not apply status:verified.

If artifact_list also finds no match, fall back to the SAM MCP search:

uv run "${CLAUDE_PLUGIN_ROOT}/sam_schema/cli.py" plan list --search "{slug}-followup"

Use the parent plan's resolved {slug}.

If both artifact_read and the SAM search return empty: skip the entire routing section (no follow-ups to route).

Error handling: If the SAM fallback returns plans from a different feature slug, filter results
to the parent {slug}. Store each retained result's opaque plan_ref for follow-up operations.

Steps 2–5: Route Follow-ups to Backlog

Execute the full follow-up routing procedure defined in ./references/recursive-follow-up-handling.md.

Summary:

• Step 2: Derive a search slug from each follow-up plan's feature; search backlog by title then topic
• Step 3: Classify scope (in-scope vs out-of-scope); route out-of-scope directly to backlog
• Step 4: Link follow-up plan to matched backlog item, or create a new item if no match
• Step 5: Recursion Gate — Guards (depth limit, RT-ICA BLOCKED) then Conditions (slug match + High priority)

Apply status:verified Label

After all phases and follow-up routing complete, apply verified status to the parent work item.

Beads backend: No dh:state:verified label — skip this section, continue to Final Step.

Step 1: Locate the backlog item

Use the resolved {item_ref}. If the plan did not expose an owner reference, search by its
{slug} and store the matched item's reference as {item_ref}:

uv run "${CLAUDE_PLUGIN_ROOT}/sam_schema/cli.py" backlog list --title "{slug}"

If zero items match, skip this section — there is no issue to label.

Step 2: Apply the label

Call:

mcp__plugin_dh_backlog__backlog_update(selector="{item_ref}", verified=True)

Error handling: If the call returns an error key, output:

COMPLETION BLOCKED — status:verified label could not be applied.

Error: {error}
Backlog item: {item_ref}

Fix the error (check backend credentials and access), then re-run /complete-implementation.

Stop. Do not proceed to the Final Step commit.

Final Step: Commit and Push Remaining Changes

Check for uncommitted changes and commit any remaining modifications in a single commit.

git status

Issue number in commit message: Read the current work item:

uv run "${CLAUDE_PLUGIN_ROOT}/sam_schema/cli.py" backlog view --selector "{item_ref}"

Check the issue field on the matching item. If present, append Fixes #NNN to the commit message body (NNN = GitHub integer issue number; omit for beads IDs). If no issue number is found, omit it.

Push after committing; skip if the working tree is clean.

---

Team Shutdown

After commit+push, shut down all teammates in the implementation team:

1. Read ~/.claude/teams/{team_name}/config.json to get the members list.
2. For each member name in the members array, send:

SendMessage(to="{name}", message={"type": "shutdown_request"})

3. Note: broadcast to "*" does not support structured shutdown messages — send individually
   to each named member.

---

Resolve the Issue

For both PQG and plan-linked paths, use the resolved {item_ref}. Skip this step only when the
plan has no owner reference and the fallback lookup in Apply status:verified found no work item.

uv run "${CLAUDE_PLUGIN_ROOT}/sam_schema/cli.py" backlog resolve --selector "{item_ref}" --summary "Implementation complete — AC verified PASS"

On failure: output COMPLETION BLOCKED — backlog_resolve failed: {error}. Stop.

Final Handoff Output

Execute the full procedure defined in ./references/final-handoff.md.
