spectra-ingest

Update an existing OpenSpec change — from a Claude Code plan file or conversation context.

Claude Code only. This skill can read plan files from ~/.claude/plans/ or use conversation context to update artifacts.

Prerequisites: This skill requires the spectra CLI. If any spectra command fails with "command not found" or similar, report the error and STOP.

Input: Optionally specify a plan file path or name.

• /spectra:ingest ~/.claude/plans/agile-discovering-rocket.md
• /spectra:ingest agile-discovering-rocket
• /spectra:ingest (use conversation context or auto-detect plan file)

Steps

1. Locate the requirement source

   a. Argument provided → treat as plan file reference (prepend ~/.claude/plans/ and append .md if needed)

   • If the file exists → use it as the plan file source, proceed to Step 2
   • If the file does NOT exist → report the error and stop

   b. No argument, plan file detectable:

   • Check conversation context for plan file path (plan mode system messages include the path like ~/.claude/plans/<name>.md)
   • If found and the file exists → use the AskUserQuestion tool to ask:
     • Option 1: Use the plan file
     • Option 2: Use conversation context
   • If the user picks plan file → proceed to Step 2
   • If the user picks conversation context → skip Step 2, go to Step 3

   c. No argument, no plan file detectable:

   • Check ~/.claude/plans/ for recent files
   • If recent files exist → list 5 most recent with the AskUserQuestion tool, include "Use conversation context" as an additional option
   • If the user picks a file → proceed to Step 2
   • If the user picks conversation context → skip Step 2, go to Step 3

   d. Conversation context fallback (no plan files found at all):

   • Use conversation context to update artifacts
   • If conversation context is insufficient, use the AskUserQuestion tool to get more details
   • Warn: "No plan file found. Using conversation context."

2. Parse the plan structure (skip if using conversation context)

   Claude Code plan files typically contain:

   • Title (# ...) — the high-level goal
   • Context section — background, motivation, current state
   • Stages/Steps — numbered implementation stages with goals and file lists
   • Files involved — list of files to modify/create
   • Verification section — how to test the changes

   Extract:

   • plan_title: from the H1 heading
   • plan_context: from the Context section
   • plan_stages: each numbered stage with its goal and file list
   • plan_files: all file paths mentioned
   • plan_verification: verification steps

3. Check for active changes (REQUIRED — ingest only updates existing changes)

   spectra list --json
   

   Parse the JSON output to get the list of active changes.

   • If one active change exists → use the AskUserQuestion tool to confirm updating it
   • If multiple active changes exist → use the AskUserQuestion tool to let user pick which one to update
   • If no active changes → tell the user: "No active change found. Use /spectra:propose first to create one." and stop

4. Select the change

   After selecting the change, check if it is parked:

   spectra list --parked --json
   

   If the selected change appears in the parked array:

   • Inform the user that this change is currently shelved (暫存)
   • Use AskUserQuestion tool to ask: continue (un-shelve) or cancel
   • If continue: run spectra unpark "<name>" then proceed
   • If cancel: stop the workflow

   Read existing artifacts for context before updating.

5. Update artifacts

   For each artifact, get instructions first:

   spectra instructions <artifact-id> --change "<name>" --json
   

   Use the template from instructions as the output structure. Apply context and rules as constraints but do NOT copy them into the file.

   The instructions JSON includes locale — the language to write artifacts in. If present, you MUST write the artifact content in that language. Exception: spec files (specs/*/*.md) MUST always be written in English regardless of locale, because they use normative language (SHALL/MUST).

   Plan-to-Artifact Mapping (when using a plan file):

   Plan Section	Artifact	How to Map
   Title	Change name	Convert to kebab-case
   Context	proposal: Why	Direct content transfer
   Stages overview	proposal: What	Summarize all stages
   Individual stages	tasks.md groups	One stage = one ## heading, sub-items = - [ ]
   File paths	proposal: Impact	Affected code list
   Verification steps	tasks.md	Final verification task group

   Context-to-Artifact Mapping (when using conversation context):

   Conversation Element	Artifact	How to Map
   Goal / requirement	proposal: Why	Extract motivation from discussion
   Discussed approach	proposal: What	Summarize agreed approach
   Mentioned files	proposal: Impact	Affected code list
   Discussion phases	tasks.md groups	One topic = one ## heading

   When updating an existing change:

   • Merge new context into existing proposal (don't replace)
   • Add new tasks from plan stages or conversation, preserve completed [x] items
   • Preserve existing [P] markers on tasks that still qualify
   • Do NOT remove existing content

   Parallel task markers ([P]): When creating or updating the tasks artifact, first read openspec/config.yaml. If parallel_tasks: true is set, add [P] markers to new tasks that can be executed in parallel. Format: - [ ] [P] Task description. A task qualifies for [P] if it targets different files from other pending tasks AND has no dependency on incomplete tasks in the same group. When parallel_tasks is not enabled, do NOT add [P] markers — but still preserve any existing [P] markers already in the file.

   After creating each artifact, re-check status:

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

   Continue until all applyRequires artifacts are complete. Show progress: "✓ Created "

6. Analyze-Fix Loop (max 2 iterations)

   spectra analyze <name> --json
   

   1. Filter findings to Critical and Warning only (ignore Suggestion)
   2. If no Critical/Warning findings → show "Artifacts look consistent ✓" and proceed
   3. If Critical/Warning findings exist: a. Show: "Found N issue(s), fixing... (attempt M/2)" b. Fix each finding in the affected artifact c. Re-run spectra analyze <name> --json d. Repeat up to 2 total iterations
   4. After 2 attempts, if findings remain:
      • Show remaining findings as a summary
      • Proceed normally (do NOT block)

7. Validation

   spectra validate "<name>"
   

   If validation fails, fix errors and re-validate.

8. Summary and next steps

   Show:

   • Source used: plan file (<path>) or conversation context
   • Change name and location
   • Artifacts created/updated
   • Validation result

   Use AskUserQuestion tool to confirm the workflow is complete. This ensures the workflow stops even when auto-accept is enabled. Provide exactly these options:

   • First option (will be auto-selected): "Done" — End the ingest workflow. Inform the user they can run /spectra:apply <change-name> when ready.
   • Second option: "Apply" — Invoke /spectra:apply <change-name> to start implementation.

   If AskUserQuestion tool is not available, display the summary and inform the user to run /spectra:apply <change-name> when ready. Then STOP — do not continue.

   After the user responds, if they chose "Done", the workflow is OVER. If they chose "Apply", invoke /spectra:apply <change-name> to begin implementation.

Guardrails

• NEVER modify the original plan file in ~/.claude/plans/
• NEVER write application code — this skill only creates/updates OpenSpec artifacts
• NEVER create new changes — ingest only updates existing changes. If no active change exists, direct user to /spectra:propose
• When updating existing changes, preserve all completed tasks ([x]) — never revert progress
• If the source content is too brief to fill all artifact sections, use the AskUserQuestion tool to get more details rather than inventing content
• If spectra CLI is not available, report the error and stop
• Verify each artifact file exists after writing before proceeding to next
• NEVER skip the artifact workflow to write code directly
• If AskUserQuestion tool is not available, ask the same questions as plain text and wait for the user's response
