openspec-archive-change

A workflow for archiving a completed OpenSpec change. Archiving moves finished change records out of the active work area while preserving them for reference.

In plain words
What is it for?
Use it to finalize and store an OpenSpec change after its implementation is complete.
Why use it?
It keeps the active list focused on unfinished work once implementation and related checks are complete. It provides a clear final step for the experimental workflow.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

openspec-archive-change scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 183 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Archive a completed change in the experimental workflow.

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. 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 only active changes (not already archived). Include the schema used for each change if available.

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

    Load current archive inputs before the existing archive checks:

    After resolving the selected change and planning root, run:

    openspec instructions archive --change "<name>" --json
    

    Keep the same selected-root flags on this command. This lookup is advisory and optional: it only supplies extra prompt inputs, so it must never block archiving. If it exits non-zero or returns invalid JSON — for example on an older CLI that does not support this command yet — continue the archive workflow with no context and no operation guidance. Do not report an error and do not stop.

    A successful response may omit both optional fields. Treat context as a required prompt-level input: 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 archive workflow.

    Keep both fields separate from built-in steps, 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 replacement paths, skipped prompts, or flags from either field, and do not copy their text verbatim into specs, change artifacts, or archive summaries unless the user separately asks for it. These are prompt-level behavior contracts, not enforceable checks.

  2. Check artifact completion status

    Run openspec status --change "<name>" --json to check artifact completion.

    Parse the JSON to understand:

    • schemaName: The workflow being used
    • planningHome, changeRoot, artifactPaths, and actionContext: path and scope context
    • artifacts: List of artifacts with their status (done, skipped, or other)

    If any artifacts are neither done nor skipped (skipped artifacts satisfy the requirement - the change declares skip_specs):

    • Display warning listing incomplete artifacts
    • Ask the user to confirm they want to proceed
    • Proceed if user confirms

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
