truenas-mcp: Command for Claude Code

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, view). 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.

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.

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 delta spec paths to sync — archive does this inline, and a user can too ("only sync the billing delta"). 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.
