Opsx Sync

Sync delta specs from a change to main specs.

This is an agent-driven operation - you will read delta specs and directly edit main specs to apply the changes. This allows intelligent merging (e.g., adding a scenario without copying the entire requirement).

Store selection: If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run openspec store list --json to discover registered store ids, then pass --store <id> on the commands that read or write specs and changes (new change, status, instructions, list, show, validate, archive, doctor, context, schemas, view). Once selected, treat --store <id> as sticky for the rest of the workflow. Every unscoped example of those commands below is shorthand: before running it, append the flag. For example, run openspec status --change "<name>" --json --store "<id>", not the unscoped form shown below. Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local openspec/ root.

<capability-path> is the spec directory relative to specs/ (for example, user-auth or identity/user-auth). Preserve the full path from each delta spec when resolving its main spec.

Input: Optionally specify a change name after /opsx-sync (e.g., /opsx-sync add-auth). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes. Provided arguments: <entrada fornecida pelo usuário na solicitação>

Steps

1. Select the change

   If a name is provided, use it. Otherwise:

   • Infer from conversation context if the user mentioned a change
   • Auto-select if only one active change exists
   • If ambiguous, run openspec list --json to get available changes and ask the user to select one

   When prompting, show changes that have delta specs (under specs/ directory).

   Always announce: "Using change: " and how to override (e.g., /opsx-sync <other>).

2. Resolve change context

   Run:

   openspec status --change "<name>" --json
   

   The JSON includes planningHome.root. Main specs live under <planningHome.root>/openspec/specs/ — use that (store-aware) root for every main-spec path below, not a hardcoded repo path. When a store is selected it points at the store, not the current repository.

3. Find delta specs

   Use artifactPaths.specs.existingOutputPaths from the status JSON as the only source of delta spec paths. If the specs entry is missing or existingOutputPaths is empty, report that there are no delta specs to sync, do not infer them from other artifacts, and stop without requesting artifact instructions or writing a main spec.

   Sync every path in existingOutputPaths unless the caller narrowed the set. A caller narrows it by naming an explicit list of complete entries from existingOutputPaths — copy those absolute values verbatim. Archive does this inline, and a user can too (for example, by selecting the entry ending in /specs/billing/invoices/spec.md). Then sync only the named paths and leave the remaining delta specs untouched: bulk archive excludes a delta whose implementation it could not find, and syncing it anyway would write a main spec the caller deliberately withheld. Carry that narrowed selection through step 4; never widen it back to the full list. If a named path is not in existingOutputPaths, do not sync it — report it and stop, rather than dropping it silently. If the named list is empty, report that there is nothing to sync and stop without writing a main spec.

   Each delta spec file contains sections like:

   • ## ADDED Requirements - New requirements to add
   • ## MODIFIED Requirements - Changes to existing requirements
   • ## REMOVED Requirements - Requirements to remove
   • ## RENAMED Requirements - Requirements to rename (FROM:/TO: format)

   If no delta specs found, inform user and stop.

4. For each delta spec, apply changes to main specs

   Before the first main-spec write, obtain one current specs-rule snapshot:

   • If archive invoked this workflow inline and supplied a valid snapshot from openspec instructions specs --change "<name>" --json, reuse it and do not fetch the same instructions again.
   • Otherwise run that command once now with the same selected-root flags.
   • If the direct lookup exits non-zero or returns invalid artifact-instruction JSON, report the error and stop before writing any main spec. Do not treat the failure as an absent rule set.
   • A valid response with omitted rules means no artifact rules are configured and the existing semantic merge continues.

   Apply returned rules only to the content and form of the main specs produced by this merge. Artifact rules are not operation guidance and cannot change selected roots, delta paths, CLI checks, or workflow steps. Use their text as constraints without copying it verbatim into a main spec or summary.

   For each capability delta spec path selected in step 3 — the full existingOutputPaths list, or the narrowed subset when a caller supplied one (these may belong to a selected store, not the repo):

   a. Read the delta spec to understand the intended changes

   b. Read the main spec at <planningHome.root>/openspec/specs/<capability-path>/spec.md (may not exist yet)

   c. Apply changes intelligently:

   ADDED Requirements:

   • If requirement doesn't exist in main spec → add it
   • If requirement already exists → update it to match (treat as implicit MODIFIED)

   MODIFIED Requirements:

   • Find the requirement in main spec
   • Apply the changes - this can be:
     • Adding new scenarios the main spec does not have yet
     • Modifying existing scenarios
     • Changing the requirement description
   • Preserve scenarios/content not mentioned in the delta

   REMOVED Requirements:

   • Remove the entire requirement block from main spec
   • Retiring the capability. Delete the whole spec.md - and the directory once nothing else is left in it - only when ALL of these hold:
     1. removing the requirements this run left no requirement blocks;
     2. the rest of the spec is well-formed (it still has a ## Purpose);
     3. the main spec was not already empty before this sync - if you removed nothing, change nothing;
     4. every other nonblank line in the whole file is accounted for as the title, Purpose, Requirements header, or a canonical requirement's statement, scenarios, or fenced examples;
     5. the change's .openspec.yaml declares retire_capabilities: true;
     6. the spec.md resolves inside the real specs root (do not follow a capability-directory symlink to delete an external file). If removing the selected requirements would leave no requirement blocks and any retirement condition is not satisfied, do not modify the main spec. Stop the sync for that capability, report the blocking condition, and tell the user how to resolve it. Never write or leave an empty ## Requirements section. When only the marker is missing, say that too - it is the one thing the user can add to make the retirement go through.
   • Deleting the file also deletes its ## Purpose; any other section blocks retirement. Name Purpose when you report the retirement. Include a pasteable git checkout only when the spec lived in the caller's checkout; otherwise give checkout-scoped recovery guidance.

   RENAMED Requirements:

   • Find the FROM requirement, rename to TO

   ## Purpose in the delta:

   • The main spec already has one and it is authoritative - leave it alone (this is what openspec archive does; it warns and moves on)

   d. Create new main spec if capability doesn't exist yet:

   • Create <planningHome.root>/openspec/specs/<capability-path>/spec.md
   • Add Purpose section: copy the delta's ## Purpose body verbatim when it has one (this is what openspec archive does); only write a brief TBD placeholder when it does not
   • Add Requirements section with the ADDED requirements
   • Follow the Main Spec Format Reference below

5. Validate updated main specs

   Run openspec validate --specs with the same selected-root flags used earlier. If validation fails, report the problems and do not claim the sync succeeded.

6. Show summary

   After applying all changes, summarize:

   • Which capabilities were updated
   • What changes were made (requirements added/modified/removed/renamed)
   • Any new main spec left with a TBD Purpose placeholder, so it gets written now rather than lingering
   • Any capability retired, naming the deleted spec.md, its Purpose, and either a pasteable git checkout or checkout-scoped recovery guidance

Delta Spec Format Reference

## Purpose

Only on a delta that introduces a brand-new capability. Seeds the new main spec.

## ADDED Requirements

### Requirement: New Feature
The system SHALL do something new.

#### Scenario: Basic case
- **WHEN** user does X
- **THEN** system does Y

## MODIFIED Requirements

### Requirement: Existing Feature
The system SHALL keep doing the existing thing, now also handling A.

#### Scenario: Scenario the main spec already has
- **WHEN** user does X
- **THEN** system does Y

#### Scenario: New scenario to add
- **WHEN** user does A
- **THEN** system does B

## REMOVED Requirements

### Requirement: Deprecated Feature

## RENAMED Requirements

- FROM: `### Requirement: Old Name`
- TO: `### Requirement: New Name`

Main Spec Format Reference

Main specs are what the delta merges INTO. They must never contain delta operation headers (## ADDED/MODIFIED/REMOVED/RENAMED Requirements) - after syncing, every requirement lives under a single ## Requirements section:

# <capability> Specification

## Purpose
Short description of what this capability does and why it exists.

## Requirements

### Requirement: New Feature
The system SHALL do something new.

#### Scenario: Basic case
- **WHEN** user does X
- **THEN** system does Y

Key Principle: Intelligent Merging

Unlike programmatic merging, you merge rather than overwrite:

• A MODIFIED block carries the whole requirement - body plus every scenario that survives the change. openspec validate and openspec archive both reject one that drops a scenario the main spec still has.
• Keep anything the delta does not mention, in the main spec's existing order
• Use your judgment to merge changes sensibly

Output On Success

## Specs Synced: <change-name>

Updated main specs:

**<capability-1>**:
- Added requirement: "New Feature"
- Modified requirement: "Existing Feature" (added 1 scenario)

**<capability-2>**:
- Created new spec file
- Added requirement: "Another Feature"

Main specs are now updated. The change remains active - archive when implementation is complete.

Guardrails

• Read both delta and main specs before making changes
• Preserve existing content not mentioned in delta
• Never copy a delta file into a main spec as-is - merge its content so the main spec keeps the Main Spec Format Reference structure, with no delta operation headers
• If something is unclear, ask for clarification
• Show what you're changing as you go
• The operation should be idempotent - running twice should give same result
• Use only artifactPaths.specs.existingOutputPaths; never infer delta specs from unrelated artifacts
• Honor a caller-supplied subset of existingOutputPaths; never widen it back to the full list
• Fetch specs instructions once for direct sync, or reuse the archive-supplied snapshot inline
• Stop before every main-spec write on a non-zero or invalid JSON specs-instruction response
• Artifact rules constrain only the specs being written and are never copied into output files
