Openspec Bulk Archive Change

Archive multiple completed changes in a single operation.

This skill allows you to batch-archive changes, handling spec conflicts intelligently by checking the codebase to determine what's actually implemented.

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.

Project check: These steps expect a project that already uses OpenSpec. Before the first step that writes anything (new change, archive, sync specs, or authoring an artifact file), confirm the project has a root: run openspec list --json (with --store <id> when a store is selected, since the store is then the root) and read root. A root object means the project is set up. "root": null means it is not - there is no openspec/ directory here, and a write such as openspec new change would create one as a side effect. The command also exits non-zero, which is that answer rather than a broken CLI, so read the JSON instead of retrying or working around it.

One "root": null is not about setup: when a status error message starts with Declared in or Invalid store declaration in and names this project's openspec/config.yaml (or config.yml), the project does use OpenSpec through a store it declares, which this machine cannot resolve (the store is not registered, or the store: line is malformed). Do not treat it as uninitialized and skip the branches below: stop before writing and show the user that error's message and fix.

Otherwise, with no root, what happens next depends on how this workflow was reached:

• Auto-selected: you chose this workflow yourself, without the user naming OpenSpec, naming this skill, or running its slash command. Stop using OpenSpec and answer the request normally, as you would with no OpenSpec installed. Do not ask them to set anything up and do not mention OpenSpec setup.
• Explicit OpenSpec request: the user named OpenSpec, named this skill, or ran its slash command. Stop before writing and ask how to proceed: set this project up (openspec init), target a store they already have (--store <id>), or continue without OpenSpec for this request. Wait for their answer.

In both branches, never create the root as a side effect: do not run openspec init until the user asks for it, do not hand-create openspec/ files, and do not let a command create it.

<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: None required (prompts for selection)

Steps

1. Get active changes

Run openspec list --json to get all active changes.

If no active changes exist, inform user and stop.

1. Prompt for change selection

Ask the user to choose changes (multi-select):

• Show each change with its schema
• Include an option for "All changes"
• Allow any number of selections (1+ works, 2+ is the typical use case)

IMPORTANT: Do NOT auto-select. Always let the user choose.

Load current archive inputs once for the selected root before batch validation:

Choose one selected change from this root and run openspec instructions archive --change "<selected-change>" --json with the same selected-root flags. This lookup is advisory and optional: it only supplies extra prompt inputs, so it must never block the batch. If it fails or returns invalid JSON — for example on an older CLI that does not support this command yet — continue the batch with no context and no operation guidance. Do not report an error and do not stop.

A valid response may omit context and operationGuidance. Treat context as a required prompt-level input across the batch: read and consider it, and apply relevant project facts, conventions, and constraints. Treat operationGuidance as optional additive advice: read and consider every entry, and follow entries that are applicable and compatible with the built-in batch workflow.

Keep both fields separate from conflict analysis, explicit user choices, resolved paths, CLI checks, and command contracts. If context conflicts with one of those controlling inputs, report the conflict and preserve the controlling value. If guidance is inapplicable or conflicts with a controlling input, do not follow it and explain why. Do not infer skipped prompts, replacement paths, or flags from either field, and do not copy their text verbatim into specs, changes, or summaries. These are prompt-level behavior contracts, not enforceable checks.

1. Batch validation - gather status for all selected changes

For each selected change, collect:

a. Artifact status - Run openspec status --change "<name>" --json

• Parse schemaName, artifacts, planningHome, changeRoot, artifactPaths, and actionContext
• Note which artifacts are done vs other states

b. Task completion - Read artifactPaths.tasks.existingOutputPaths from status JSON

• Complete means the checkbox holds only x/X, ignoring spacing (- [ x] is complete); every other marker is incomplete (- [ ], - [], and unfamiliar ones such as - [~] or - [-])
• If no tasks file exists, note as "No tasks"

c. Delta specs - Check artifactPaths.specs.existingOutputPaths from status JSON

• List which capability specs exist
• For each, extract requirement names (lines matching ### Requirement: <name>)
• Treat this list as the only delta-spec source. If the specs entry is missing or the list is empty, perform no spec sync or specs-instruction lookup for that change; do not infer deltas from unrelated artifacts.
• Evaluate this independently for every change, including mixed-schema batches where some schemas have no specs artifact.

d. Archive target - Compute each change's target name once and record it as that change's <target-name>

• Use the change name as-is when it already starts with a YYYY-MM-DD- prefix; otherwise prepend the current date as YYYY-MM-DD-<name> (same rule as openspec archive)
• Check whether <planningHome.changesDir>/archive/<target-name> already exists
• If it exists, or another selected change resolves to the same target name, mark every such change Blocked with Archive directory already exists
• A blocked change is never synced or moved: show it as Blocked in the step 6 table, leave it out of conflict resolution (resolve its conflicts using only the other changes), and record it as Failed in step 8d
• Checking here, before any main spec is written, matches openspec archive: a collision found after sync would leave main specs rewritten for an archive that never happened

1. Detect spec conflicts

Build a map keyed by <capability-path>, the exact path relative to specs/:

   identity/user-auth -> [change-a, change-b]  <- CONFLICT (2+ changes)
   billing/user-auth  -> [change-c]            <- OK (different full path)
