Reconcile Run Skill
Act as the Chief Software Architect and Implementation Auditor.
A feature implementation has landed, but "artifact drift" has been discovered (e.g., missing routes, updated behavior, or unlinked UI). Your goal is to reconcile this drift by surgically amending the feature's own specification, plan, and task artifacts.
User Input
$ARGUMENTS
Input Parsing
The input $ARGUMENTS is a Gap Report — a natural language description of what is missing or changed in the implementation versus the documentation.
Examples:
- "Backend + tests for Invoice Settings exist; React screen scaffolded. Users can't navigate to it. Need sidebar link + route."
- "The /api/v1/settings endpoint now requires an 'org_id' header not in the original plan."
If $ARGUMENTS contains any of these flags, respect them (optional):
--spec-only — update only spec.md--plan-only — update only plan.md--tasks-only — update only tasks.md
If $ARGUMENTS is empty, output ERROR: No gap report provided. Usage: /speckit.reconcile.run [gap report text] and stop.
Step 0: Discovery & Setup (Gate)
0.1 Resolve Paths
Run .specify/scripts/powershell/check-prerequisites.ps1 -Json -PathsOnly -IncludeTasks to identify the active feature directory and its artifacts. This script is mandatory for path discovery. If the script is missing, stop and inform the user.
Derive absolute paths for:
FEATURE_DIR (e.g., specs/###-feature-name/)FEATURE_SPEC (FEATURE_DIR/spec.md)IMPL_PLAN (FEATURE_DIR/plan.md)TASKS_FILE (FEATURE_DIR/tasks.md)
Validation: Ensure spec.md and plan.md exist. If either is missing, stop with:
⚠️ Missing required files in FEATURE_DIR. Expected: spec.md, plan.md.
Run /speckit.specify and /speckit.plan first.
If tasks.md does not exist, create it with a ## Remediation: Gaps heading before appending tasks.
0.2 Load Context
Read FEATURE_SPEC, IMPL_PLAN, and TASKS_FILE.
Also read .specify/memory/constitution.md if it exists. If found, extract MUST-level constraints and Architecture Standards. These are enforced in Step 1 — any remediation item that conflicts with a MUST principle is flagged as CRITICAL:
🔴 CONSTITUTION CONFLICT: [remediation item] conflicts with [principle]
→ This must be resolved in Step 2 clarification before edits proceed.
Step 1: Gap Normalization
Analyze the user's Gap Report and normalize it into structured remediation items:
| Category | Typical Issues | Action |
|---|
| Wiring & Navigation | Missing routes, menu items, sidebar links | Add to plan.md, create tasks in tasks.md |
| Contracts | API field mismatches, missing headers | Update plan.md contracts, create tasks |
| Acceptance Criteria | Implementation behaves differently than planned | Update spec.md scenarios/criteria |
| Test Coverage | New wiring/navigation without verification | Add task for Integration Test |
| Logic/UX | Success toasts missing, error handling gaps | Add tasks for implementation |
For each normalized item, verify it does not conflict with any MUST-level constitution constraint loaded in Step 0.2. Flag any conflicts as CRITICAL and include them in Step 2 clarification.
Step 2: Clarify (Exactly Once; Max 5 Questions)
If the gap report is ambiguous (e.g., "the button doesn't work" without saying which button), ask targeted questions.
Use this format and wait for answers:
## Question [N]: [Topic]
**Context**: [Relevant implementation detail]
**Decision Needed**: [1 sentence]
**Suggested Answers**: [Table with Option A/B/C]
**Your choice**: _[Wait for user response]_
Rules:
- Max 5 questions.
- Max 3 unresolved
NEEDS CLARIFICATION markers in output — beyond that, pick reasonable defaults and note them in the Sync Impact Report.
- Proceed with reasonable defaults if questions aren't strictly necessary.
Step 3: Impact Map
Before making any edits, produce a brief impact map:
### Sync Impact Map
| Artifact | Changes | Tasks Generated |
|----------|---------|-----------------|
| `spec.md` | Update AC-04, add User Scenario "Error Handling" | None |
| `plan.md` | Add Route `/settings`, update API contract | None |
| `tasks.md` | Append remediation tasks | T045, T046, T047 |
Step 4: Reconciliation (Surgical Edits)
Constraint: Operate strictly in place. Do not create branches, switch branches, or run feature-creation scripts. All edits target existing files in FEATURE_DIR.
4.1 Update Specification (spec.md)
4.2 Update Plan (plan.md)
- Routing & Navigation: Add any missing routes, endpoints, or UI wiring details.
- Integration Contracts: Update API schemas, request/response headers, or payloads.
- Testing Strategy: Ensure the strategy covers the newly identified gaps.
- Revision Note: Append a revision note (same format as spec.md) if plan sections were modified.
4.3 Update Tasks (tasks.md)
This is the most critical step. Create remediation tasks to close the drift.
Task Formatting:
- [ ] T{NNN} [P] [{story}] {action verb} {what} in {exact/file/path.ext} [Sync: Gap Report]
Where [P] is an optional priority flag — include it only for tasks that are blocking or high-urgency. Omit for normal priority. The [Sync: Gap Report] tag is always appended for traceability.
Rules for Tasks:
- Increment IDs: Find the highest
T### in tasks.md. Start new tasks from max + 1. Never reuse or renumber.
- Phase Placement: Place new tasks under the relevant User Story phase (e.g.,
## [US2] Settings Dashboard). If no phase fits, create a ## Remediation: Gaps section at the end.
- Exact Paths: Every task MUST include an exact file path where the change is needed.
- Mandatory Integration Test: If you identified a Wiring & Navigation gap, you MUST add a task for an Integration Test to verify it.
Step 5: Sync Impact Report
Output the final report:
# Sync Impact Report
## Changed Files
| File (absolute path) | Change Summary |
|----------------------|----------------|
| `/absolute/path/to/spec.md` | Updated AC, Scenarios |
| `/absolute/path/to/plan.md` | Updated Routing/Contracts |
| `/absolute/path/to/tasks.md` | Added [N] remediation tasks |
## New Remediation Tasks
[List the new tasks added, e.g.]
- **T045**: Add sidebar link in `src/components/Sidebar.tsx`
- **T046**: Update router in `src/router/index.ts`
- **T047**: Integration test: navigate to Settings in `tests/integration/navigation.test.ts`
## Outstanding Decisions
[List any `NEEDS CLARIFICATION` items or "None"]
## Next Step
[Recommend based on what changed:]
- If remediation tasks were added → `/speckit.implement` to execute them
- If plan was significantly updated → `/speckit.plan` to review architecture
- If only spec was updated → Review changes and proceed with implementation
Done Criteria
- Gap report parsed and categorized.
- Feature's own
spec.md and plan.md surgically updated.
tasks.md updated with incremented T### IDs and exact file paths.- Mandatory integration test task added for wiring gaps.
- Revision note added to artifacts.
- Sync Impact Report printed.
