User Input
$ARGUMENTS
You MUST consider the user input before proceeding (if not empty).
Outline
You are running the preparation phases of the speckit pipeline end-to-end. The user's input (above) is the feature description that will seed the specification phase.
This skill is the prefix of speckit-opsmill-auto: it covers Specify → Plan → Critique → Tasks → Spec/Ask Alignment Check and stops before implementation. Use it when you want a feature fully designed and broken down into a tasks.md ready for review, but you do not want the agent to execute the tasks autonomously.
Execute every phase below in order, making all decisions autonomously. Do not stop to ask the user for input between phases — if a phase requires choices (e.g., clarification questions in specify, research decisions in plan), use your best judgment and proceed. The user expects a hands-off, one-shot execution up through tasks.md.
After each phase, invoke the speckit-checkpoint-commit skill to commit the artifacts produced by that phase before moving on.
Each phase below is executed by invoking the named skill (e.g. via the agent's Skill tool). Skills are agent-agnostic, so this workflow runs identically across any harness that supports skill discovery — not only those exposing speckit slash commands.
Phase 1 — Specify
Invoke the speckit-specify skill with the user's feature description ($ARGUMENTS).
- Complete the full specify workflow: generate a short name, create the spec directory, write
spec.md, run quality checks.
- If clarification questions arise, answer them yourself based on context and best judgment — do not pause for user input.
- Commit the spec artifacts.
Phase 2 — Plan
Invoke the speckit-plan skill.
- Complete the full plan workflow: research unknowns, generate
plan.md, research.md, data-model.md, API contracts, quickstart.md.
- Make all design decisions autonomously.
- Commit the plan artifacts.
Phase 3 — Critique
Invoke the speckit-critique-run skill.
- Run the dual-lens (Product + Engineering) critique against
spec.md and plan.md before any tasks are generated.
- For any 🎯 Must-Address findings, apply the suggested fixes to
spec.md / plan.md autonomously and commit them — do not pause for user approval.
- For 💡 Recommendations, apply them when the fix is clear and low-risk; otherwise note and move on.
- 🤔 Questions: resolve with your best judgment based on context (same rule as the Specify phase).
- If the verdict is 🛑 RETHINK, loop back to
speckit-plan (or speckit-specify if the spec itself is the problem), re-run the critique, then continue.
- Commit the critique report and any spec/plan updates before moving on.
Phase 4 — Tasks
Invoke the speckit-tasks skill.
- Generate the full
tasks.md with dependency-ordered, actionable tasks.
- Skip the optional
speckit-analyze skill unless something looks inconsistent — use your judgment.
- Commit the tasks artifact.
Phase 5 — Spec/Ask Alignment Check
The earlier phases can drift from a detailed PRD: clarifications get over-applied, scope creeps in from research, or requirements get rephrased away. This phase catches that before the user sees tasks.md.
5a. Decide whether to run the check
Inspect $ARGUMENTS. The check is only meaningful when the user provided a substantive PRD — either inline or by reference. Decide based on the following, in order:
$ARGUMENTS contains one or more URLs (links to a Notion / Confluence / Google Doc / GitHub issue / Linear ticket / shared Markdown / PDF). Treat each URL as a likely PRD location. Run the check.$ARGUMENTS itself looks like a detailed PRD — multiple paragraphs with structure such as headings, bullet lists of requirements, explicit goals/non-goals, acceptance criteria, or > ~400 characters of substantive description. Run the check.$ARGUMENTS is a one-line description, vague brief, or empty. Skip the check — there is no source-of-truth document to align against. Write a short note in your final summary stating you skipped this phase and why, and proceed to Completion.
5b. Resolve the source-of-truth PRD
If you decided to run the check:
- For each URL in
$ARGUMENTS, fetch its content using the harness's web fetch tool (in Claude Code: the WebFetch tool). Extract the requirement-bearing sections.
- If the harness has no web-fetch capability at all (the tool is absent, not merely failing): you cannot resolve URL-only PRDs. Fall back to any inline PRD content in
$ARGUMENTS. If the only source was a URL and there is no inline content, you cannot run a meaningful check — skip the rest of Phase 5, record verdict: ⚠️ SKIPPED — source PRD unreachable (no web-fetch tool) in the alignment report, and note it prominently in the Completion summary so the user knows alignment was not verified.
- If a URL is gated (auth required, 404, network error), record that and fall back to whatever PRD content is in
$ARGUMENTS itself. If neither is usable, skip the rest of Phase 5 with a note.
- Concatenate the fetched / inline PRD content into a single "source PRD" view that you will compare against
spec.md.
5c. Compare source PRD to spec.md
Read the current spec.md end-to-end and judge it against the source PRD. You are looking for significant drift, not stylistic differences. Significant means:
- A requirement, goal, or explicit non-goal in the PRD is missing from the spec.
- The spec adds a requirement, scope item, or constraint that does not appear in the PRD and was not a necessary clarification.
- A requirement's semantics have been changed (e.g., "users can opt out" became "admins can opt users out"; "must support 10k req/s" became "should scale").
- Acceptance criteria in the PRD are dropped or softened in the spec.
- The spec contradicts a stated PRD constraint (compatibility, deadline, dependency, etc.).
Cosmetic, structural, or expansion-of-detail differences are not drift. The spec is allowed to be longer, more precise, and to flesh out implicit requirements.
5d. Write the alignment report
Write <spec-dir>/alignment-check.md with:
- Source — which URL(s) and / or inline ask were used as the source PRD.
- Verdict — one of
✅ ALIGNED, ⚠️ MINOR DRIFT (proceeding), or 🛑 SIGNIFICANT DRIFT (re-running prep).
- Findings — table of
Severity | Category (missing / added / changed / dropped / contradicted) | PRD reference | Spec reference | Description.
- Action — what you decided to do (proceed, or re-run which phases).
Commit the report via speckit-checkpoint-commit.
5e. Remediate significant drift (with retry budget)
This step is the loop body. Initialize a remediation counter to 0 before the first entry. Enter this step whenever the most recent 5d verdict is 🛑 SIGNIFICANT DRIFT.
While the latest verdict is 🛑 SIGNIFICANT DRIFT:
- Check the budget first. If the counter is already
2, do not start another pass — go to "budget exhausted" below.
- Increment the counter (this pass now counts against the budget of 2).
- Update
spec.md by re-invoking the speckit-specify skill with an augmented input that includes:
- The original
$ARGUMENTS content (and fetched PRD body if from URL).
- An explicit list of the drift findings the spec must fix (missing requirements to add, off-scope items to remove, semantic changes to revert).
The skill will update the existing
spec.md in place.
- Re-run Phase 2 (Plan) to refresh
plan.md against the corrected spec.
- Re-run Phase 3 (Critique) to validate the corrected spec/plan.
- Re-run Phase 4 (Tasks) to regenerate
tasks.md against the corrected plan.
- Re-run Phase 5c–5d (do not re-resolve the source PRD — keep the same source) to produce a fresh verdict, then return to the top of this loop and re-evaluate it.
Loop exits:
- Aligned/minor — a pass produces
✅ ALIGNED or ⚠️ MINOR DRIFT: accept it and proceed to Completion.
- Budget exhausted — the counter reached
2 and the verdict is still 🛑 SIGNIFICANT DRIFT: stop. Update alignment-check.md with verdict 🛑 UNRESOLVED — manual review required, list the remaining findings, and surface this prominently in the Completion summary. Do not silently proceed.
Retry budget: at most 2 remediation passes, tracked by the counter above.
Commit each remediation pass's artifacts as it runs (the inner skills handle their own commits; you only need to commit the updated alignment-check.md at the end of each pass).
Completion
After all five phases are complete, provide a brief summary:
- Feature name and spec directory
- Number of tasks generated in
tasks.md
- Any critique findings that were addressed inline
- Alignment check status — verdict, source PRD reference, number of remediation passes used (if any), and any unresolved drift
- Any notable decisions you made autonomously
Machine-readable status line (REQUIRED). The final line of your output MUST be exactly:
STATUS: <READY|BLOCKED> | SPEC_DIR: <absolute spec-dir path> | REASON: <short reason or n/a>
STATUS: READY — tasks.md was generated and the alignment outcome is ✅ ALIGNED, ⚠️ MINOR DRIFT, or ⚠️ SKIPPED. Only in this state is the spec safe to implement.STATUS: BLOCKED — alignment is 🛑 UNRESOLVED after the retry budget, or any phase could not complete. This is the explicit failure signal the parent speckit-opsmill-auto checks before deciding whether to start implementation; do not dress an unresolved run up as a success.SPEC_DIR MUST be the absolute path to the spec directory, so the parent can hand it to the implement phase without parsing prose.
Keep this as the literal last line, unwrapped.
Do not proceed to implementation, review, or extraction. The user will run those phases (or speckit-opsmill-auto from scratch) when ready.
