Spectra Ingest

Update an existing Spectra change — from a plan file or conversation context.

Plan file support is available when the tool has a plan directory (~/.claude/plans/). Otherwise, 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:

   • Resolve the canonical plan root from ~/.claude/plans/ first.
   • If the input is a plain name (no / or \\, not absolute, and not prefixed with ~), resolve it under the canonical plan root and append .md only if that candidate exists.
   • If the input is an explicit path, accept only an absolute path or a path prefixed with ~; expand ~, reject .. path components, canonicalize the existing file, and require the canonical result to remain under the canonical plan root. Reject missing files and symlink targets that escape the plan root.
   • Use only the resolved canonical file as the plan source. Never prepend the plan root to an explicit path or read an uncanonicalized path.
   • If the resolved 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
   

   Also check for parked changes:

   spectra list --parked --json
   

   Parse both JSON outputs to get the full list of changes (active + parked). Parked changes should be annotated with "(parked)" in any selection list.

   • If one change exists (active or parked) → use the AskUserQuestion tool to confirm updating it
   • If multiple changes exist → use the AskUserQuestion tool to let user pick which one to update
   • If no changes at all (neither active nor parked) → 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 parked（暫存）
   • Use AskUserQuestion tool to ask: continue (unpark) or cancel
   • If continue: run spectra unpark "<name>" then proceed
   • If cancel: stop the workflow

   If there is no AskUserQuestion tool available (non-Claude-Code environment): Inform the user that this change is currently parked（暫存）and ask via plain text whether to unpark and continue, or cancel. Wait for the user's response. If the user confirms, run spectra unpark "<name>" then proceed.

   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).

   Read outputPath (or resolvedOutputPath) from the instructions and verify that it is inside the selected change directory. Generate the artifact in memory, then invoke the corresponding spectra new artifact ... --stdin command through a process API with the generated content passed via stdin. Use spectra new artifact spec <capability-name> --change "<name>" --stdin for specs and spectra new artifact <artifact-id> --change "<name>" --stdin for all other artifacts. Do not place plan, user, or conversation content in a shell heredoc, command substitution, or interpolated script. After every write, verify the output file exists at the instructed path and rerun spectra status --change "<name>" --json before continuing.

   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 .spectra.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 when it has no data dependency on another incomplete task and its modification region does not overlap another pending task, including when both tasks target different regions of the same file. 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. Inline Self-Review (before CLI analysis)

   After updating all artifacts, scan them manually. Fix issues inline, then proceed to the CLI analyzer.

   Check 1: No Placeholders

   These patterns are artifact failures — fix each one before proceeding:

   • "TBD", "TODO", "FIXME", "implement later", "details to follow"
   • Vague instructions: "Add appropriate error handling", "Handle edge cases", "Write tests for the above"
   • Delegation by reference: "Similar to Task N" without repeating specifics
   • Steps describing WHAT without HOW: "Implement the authentication flow" (what flow? what steps?)
   • Empty template sections left unfilled
   • Weasel quantities: "some", "various", "several" when a specific number or list is needed

   Check 2: Internal Consistency

   • Does every capability in the proposal have a corresponding spec?
   • Does the design reference only capabilities from the proposal?
   • Do tasks cover all design decisions, and nothing outside proposal scope?
   • Are file paths consistent across proposal Impact, design, and tasks?

   Check 3: Scope Check

   • More than 15 pending tasks → consider decomposing into multiple changes
   • Any single task would take more than 1 hour → split it
   • Touches more than 3 unrelated subsystems → consider splitting

   Check 4: Ambiguity Check

   • Are success/failure conditions testable and specific?
   • Are boundary conditions defined (empty input, max limits, error cases)?
   • Could "the system" refer to multiple components? Be explicit.

   Check 5: Preservation Check (ingest-specific)

   • Are all completed tasks [x] still present and unchanged?
   • Were existing [P] markers preserved on tasks that still qualify?
   • Was existing content merged (not replaced)?

   Check 6: Durable Handoff Review (run BEFORE the CLI analyzer)

   The updated change has to survive being parked or handed to another agent. Reject and fix any of the following on incomplete design and task content (do not rewrite completed [x] tasks):

   • File-path-only tasks: a pending task whose entire description is "edit file X" with no behavior, contract, or verification target. File paths are locator context — the task SHALL still describe what is observably true when complete.
   • Line-number-coupled instructions: design or task content that points to "line 42" / "the function on lines 80-95" as the only way to identify the work. Source line numbers drift; name the function, command, struct, or behavior instead.
   • Vague acceptance criteria: success conditions like "works correctly", "behaves as expected", "handles edge cases" without naming the observable behavior or the verification target (test name, CLI invocation, analyzer rule, manual assertion).
   • Missing scope boundaries on non-trivial work: design lacking explicit "in scope" / "out of scope" lines for any change that touches more than one subsystem or introduces new behavior. Trivial artifact-only edits MAY skip this; runtime, build, or tooling effects MUST NOT.

   Fix every failure inline using the existing context and the new plan/conversation source before running the CLI analyzer. Update incomplete design and task content so behavior contracts, verification criteria, and scope boundaries stay current with the new context. Preserve completed tasks unchanged.

Rationalization Table

7. 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
      • If any Critical finding remains, stop the workflow; do not continue to summary, apply, or downstream steps
      • If only Warning findings remain, continue the normal ingest flow after reporting them

8. Validation

   spectra validate "<name>"
   

   If validation fails, fix errors and re-validate.

9. 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 Spectra 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
