openspec-continue-change

A workflow helper for OpenSpec, a system for describing software changes through a series of written artifacts. It creates the next artifact in an existing change workflow.

In plain words
What is it for?
Use it to continue an OpenSpec change, check its current status, choose a change when several exist, and create the next required artifact.
Why use it?
It shows what remains in a change and keeps work moving in the required order instead of guessing which document or step comes next.

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-continue-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 yesterday.

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.

How it starts

The opening of the file, as written. The whole thing — 119 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Continue working on a change by creating the next artifact.

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. If no change name provided, prompt for selection

    Run openspec list --json to get available changes sorted by most recently modified. Then use the AskUserQuestion tool to let the user select which change to work on.

    Present the top 3-4 most recently modified changes as options, showing:

    • Change name
    • Schema (from schema field if present, otherwise "spec-driven")
    • Status (e.g., "0/5 tasks", "complete", "no tasks")
    • How recently it was modified (from lastModified field)

    Mark the most recently modified change as "(Recommended)" since it's likely what the user wants to continue.

    IMPORTANT: Do NOT guess or auto-select a change. Always let the user choose.

  2. Check current status

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

    Parse the JSON to understand current state. The response includes:

    • schemaName: The workflow schema being used (e.g., "spec-driven")
    • artifacts: Array of artifacts with their status ("done", "ready", "blocked")
    • isComplete: Boolean indicating if all artifacts are complete
  3. Act based on status:


    If all artifacts are complete (isComplete: true):

    • Congratulate the user
    • Show final status including the schema used
    • Suggest: "All artifacts created! You can now implement this change or archive it."
    • STOP

    If artifacts are ready to create (status shows artifacts with status: "ready"):

    • Pick the FIRST artifact with status: "ready" from the status output
    • Get its instructions:
      openspec instructions <artifact-id> --change "<name>" --json
      
    • Parse the JSON. The key fields are:
      • context: Project background (constraints for you - do NOT include in output)
      • rules: Artifact-specific rules (constraints for you - do NOT include in output)
      • template: The structure to use for your output file
      • instruction: Schema-specific guidance
      • outputPath: Where to write the artifact
      • dependencies: Completed artifacts to read for context
    • Create the artifact file:
      • Read any completed dependency files for context
      • Use template as the structure - fill in its sections
      • Apply context and rules as constraints when writing - but do NOT copy them into the file
      • Write to the output path specified in instructions
    • Show what was created and what's now unlocked
    • STOP after creating ONE artifact

    If no artifacts are ready (all blocked):

    • This shouldn't happen with a valid schema
    • Show status and suggest checking for issues
  4. After creating an artifact, show progress

    openspec status --change "<name>"
    

Output

After each invocation, show:

  • Which artifact was created
  • Schema workflow being used
  • Current progress (N/M complete)
  • What artifacts are now unlocked
  • Prompt: "Want to continue? Just ask me to continue or tell me what to do next."

Artifact Creation Guidelines

The artifact types and their purpose depend on the schema. Use the instruction field from the instructions output to understand what to create.

Common artifact patterns:

spec-driven schema (proposal → specs → design → tasks):

  • proposal.md: Ask user about the change if not clear. Fill in Why, What Changes, Capabilities, Impact.
    • The Capabilities section is critical - each capability listed will need a spec file.
  • specs//spec.md: Create one spec per capability listed in the proposal's Capabilities section (use the capability name, not the change name).
  • design.md: Document technical decisions, architecture, and implementation approach.
  • tasks.md: Break down implementation into checkboxed tasks.

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.
