SpecKit New Feature Workflow

This is the primary entry point for all new features. It combines requirements gathering, planning, and a questions gate into a single conversational flow, then hands off to autonomous execution.

Arguments: $ARGUMENTS

Vault Logging

Throughout this action, log significant events to the vault session log. Read the session log path from .smith/vault/.current-session. If the file is missing or the vault is not initialized, skip all logging silently.

Append entries to the session log using this format:

### [HH:MM:SS] /smith-new <event>

**User Request:**
> <verbatim user message that triggered this action — capture the exact words the user typed, including any conversation context that led to the request. For natural language triggers, capture the trigger message. For explicit /smith-new invocations, capture $ARGUMENTS.>

**Synthesized Input:** <brief summary of what's being built>
**Outcome:** <what happened>
**Artifacts:** <files created/modified>
**Systems affected:** <system IDs>

Log at these points:

1. On invocation — capture the verbatim user request AND the synthesized feature description
2. After system detection — which primary system was identified, which other systems are affected
3. After spec creation — path to created spec folder and spec.md
4. After questions generated — how many questions, path to questions file
5. After questions answered — summary of each answer (topic + decision, not full text)
6. On handoff to build — note that /smith-build autonomous phase was triggered

Subagent Invocation Logging

Immediately before every Agent tool call in this workflow, append a block to the session log. The Agent tool's return value does not expose subagent_type or model to the parent, so this is the only place that information can be captured.

### [HH:MM:SS] Subagent invoked: <description>

**Type:** <subagent_type or "general">
**Model:** <model override passed to Agent, or "inherited" if none>

After the Agent tool returns, the subagent-vault-writeback.sh hook automatically appends a matching "Subagent completed" block with metrics read from the sidechain transcript — do not duplicate that logging in the skill.

Natural Language Triggers

If the user says any of the following (or similar phrases) during a conversation, treat it as invoking this command using the full conversation context as the feature description:

• "start a smith workflow"
• "let's smith this"
• "kick off a new feature for this"
• "let's build this"
• "start a new workflow for this"
• "can you smith this"

When triggered by natural language, synthesize the entire conversation history into a comprehensive feature description and proceed as if that description was passed as $ARGUMENTS.

Phase 0: Pre-Change Exploration (Conditional)

Before creating a worktree, check if the proposed feature warrants impact analysis.

When to Run Exploration

Run /smith-explore automatically if ANY of these conditions are met:

• $ARGUMENTS or conversation context mentions: "skill", "hook", "constitution", "CLAUDE.md", "MEMORY.md", "config", "policy"
• The feature touches core Smith infrastructure (.claude/skills/, .smith/, .specify/)
• --explore flag is passed explicitly

Exploration Flow

1. Run /smith-explore with the feature description and scope auto-detected from context
2. Wait for the exploration report — this produces a structured analysis of:
   • Skills affected
   • Configuration file conflicts (per File Purpose Policy in constitution.md §VI)
   • Hooks that might be impacted
   • Cross-system architectural concerns
3. Evaluate exploration status:
   • clear: Continue to Phase 1 (worktree creation)
   • conflicts-found (warnings only): Present summary to user, ask to proceed or resolve first
   • blocking-issues: STOP. Present blocking issues and require resolution before continuing

Skip Exploration

If none of the trigger conditions are met, skip directly to Phase 1. Exploration adds overhead and is only valuable for changes that may have system-wide impacts.

Phase 1: Worktree Creation & Setup

The worktree is created after exploration passes (or is skipped). This ensures the user's current working directory and branch are never touched — the entire workflow is isolated from the start.

0. Activate workflow tracking — invoke the shipped helper to create the per-branch marker. The workflow-gate hook (PR #20) exempts this exact helper by basename so the bootstrap runs even when no marker exists yet (per spec/31-workflow-gate-bootstrap). The helper also stamps the current session log with a workflow-start line so workflow-summary.sh --totals-only can attribute tokens to this workflow:

   # After determining branch name in step 4 and feature slug:
   ~/.smith/scripts/create-active-workflow.sh \
     --branch "$BRANCH" \
     --workflow smith-new \
     --slug "<feature-slug>" \
     --worktree "$WORKTREE_PATH"

   (Falls back to scripts/create-active-workflow.sh in repo-dev layouts.) Clear this marker at the end of Phase 6 (after merge) or if the workflow is abandoned. Use the shipped helper so this works even on projects that set Bash(rm:*) in the deny list:

   .specify/scripts/bash/clear-active-workflow.sh "$BRANCH"

1. Resolve the configured base branch, then fetch it (does NOT change the user's current branch). Smith reads the project's integration branch from the constitution; it falls back to main when unconfigured:

   BASE_BRANCH=$(.specify/scripts/bash/get-base-branch.sh)
   git fetch origin "$BASE_BRANCH"

2. Generate branch short-name (2-4 words) from $ARGUMENTS or conversation context. If no feature description is available yet (empty args, no context), use a placeholder like new-feature and rename the branch later after Phase 2.

3. Find next feature number by checking all three sources:

   • Remote branches: git ls-remote --heads origin | grep -oP '(?<=refs/heads/)\d+' | sort -n | tail -1
   • Local branches: git branch | grep -oP '^\s*\d+' | sort -n | tail -1
   • Specs directories: ls -d .specify/systems/*/features/[0-9]*-* 2>/dev/null | grep -oP '\d+(?=-)' | sort -n | tail -1
   • GitHub issues: gh issue list --limit 1 --json number --jq '.[0].number' Take the maximum across all sources and add 1.

4. Create worktree with feature branch from the configured base branch (origin/$BASE_BRANCH):

   git worktree add /tmp/smith-<slug> -b <number>-<short-name> "origin/$BASE_BRANCH"

   Store the worktree path (/tmp/smith-<slug>) as WORKTREE_PATH. The active-workflow file was already created in step 0 with the branch and worktree info.

   Note: The user's current branch is completely unaffected. They can be on any branch — main, a feature branch, even a detached HEAD — and this workflow will not interfere.

Ledger Context (Optional)

If .smith/vault/ledger/ exists and contains non-empty files, load relevant Ledger sections to inform this workflow. If the directory is missing, empty, or unreadable, skip silently — the Ledger is purely additive and never required.

1. Check: ls .smith/vault/ledger/*.md 2>/dev/null
2. If files exist, read the following sections (higher-confidence entries first, truncate at ~2000 tokens per file):
   • .smith/vault/ledger/patterns.md
   • .smith/vault/ledger/antipatterns.md
   • .smith/vault/ledger/tool-preferences.md
   • .smith/vault/ledger/edge-cases.md
   • .smith/vault/ledger/project-quirks.md
3. Use the loaded entries as additional context throughout this workflow — both during the conversational requirements-gathering phase (to know what to ask about, what failure modes to anticipate) and during spec generation (to steer the spec away from known antipatterns and toward established patterns / tool preferences). The Ledger informs judgment, it does not override spec/plan/constitution.
4. Budget violation tracking: If any Ledger file was truncated (entries were dropped to fit within the ~2000 token budget per file), increment context_budget_violations in .smith/vault/ledger/.meta.json by 1. If .meta.json does not exist, create it from the default template first. This signal tells the reconciliation system that the Ledger is too large for the configured budget.

Phase 2: Requirements Conversation

Goal: Arrive at a clear, detailed feature description through conversation. This phase is purely conversational — no file operations needed. The worktree already exists from Phase 1.

If $ARGUMENTS is empty AND no prior conversation context:

• Prompt the user: "What would you like to build?"
• Enter a conversational loop:
  • Ask clarifying questions about scope, user flows, constraints
  • Reflect back your understanding
  • Let the user refine and add detail
  • Continue until the user indicates they're satisfied (e.g., "that's it", "looks good", "let's go")

If $ARGUMENTS is provided:

• Use the provided description as the starting point
• Reflect back your understanding and ask if anything is missing
• Allow one round of refinement if the user wants to adjust

If triggered mid-conversation (natural language trigger):

• Synthesize the conversation history into a comprehensive feature description
• Present it to the user: "Based on our conversation, here's what I understand you want to build: [summary]. Anything to add or change?"
• Allow refinement

Output of Phase 2:

A complete feature description string that will be passed to the spec generation step.

Phase 3: Spec Generation (Subagent — in Worktree)

Once requirements are finalized, launch a subagent to handle spec generation. The worktree (WORKTREE_PATH) was already created in Phase 1. All file operations happen there.

If the branch was created with a placeholder name in Phase 1 (because $ARGUMENTS was empty), rename it now:

cd $WORKTREE_PATH && git branch -m <old-placeholder-name> <number>-<short-name>

Rename the active-workflow file if the branch name changed:

OLD_SAFE=$(echo "$OLD_BRANCH" | sed 's/[^a-zA-Z0-9._-]/-/g')
NEW_SAFE=$(echo "$NEW_BRANCH" | sed 's/[^a-zA-Z0-9._-]/-/g')
mv .smith/vault/active-workflows/${OLD_SAFE}.yaml .smith/vault/active-workflows/${NEW_SAFE}.yaml

1. Auto-detect primary system (reading from worktree):
   • Read all system spec files at $WORKTREE_PATH/.specify/systems/system-*/spec.md
   • Analyze the feature requirements against each system's scope, services, endpoints, and data models
   • Determine primary_system (the system most directly impacted) and also_affects (other systems touched)
   • Set the feature spec folder path to .specify/systems/<primary-system>/features/<NNN-short-name>/
   • If no single system is clearly primary (genuinely cross-cutting), use .specify/systems/cross-system/features/<NNN-short-name>/
   • Do NOT ask the user which system to use — determine this automatically
2. Create feature folder in worktree:

   mkdir -p $WORKTREE_PATH/.specify/systems/<primary-system>/features/<NNN-short-name>/checklists

   Note: Do NOT run create-new-feature.sh — the worktree creation in Phase 1 already created the branch.
3. Load spec template: Read $WORKTREE_PATH/.specify/templates/spec-template.md
4. Write spec.md to the system-routed feature folder in the worktree with frontmatter:

   ---
   feature: <NNN-short-name>
   primary_system: <system-folder-name>
   also_affects:
     - <other-system-folder-name>
   branch: <branch-name>
   created: <YYYY-MM-DD>
   status: in-progress
   ---

   Fill all sections from the requirements conversation:
   • Focus on WHAT and WHY, not HOW
   • Make informed guesses for unspecified details (document in Assumptions)
   • Maximum 0 [NEEDS CLARIFICATION] markers — all ambiguities should have been resolved in conversation
5. Write quality checklist at $WORKTREE_PATH/<feature-folder>/checklists/requirements.md
6. Validate spec against quality criteria (up to 3 iterations)

Phase 4: Plan Generation (Subagent — in Worktree)

Launch a separate subagent to generate the implementation plan. This preserves context window for the questions phase. All work happens in WORKTREE_PATH.

The subagent should:

1. Run setup script (from worktree):

   cd $WORKTREE_PATH && .specify/scripts/bash/setup-plan.sh --json

   Parse JSON for FEATURE_SPEC, IMPL_PLAN, SPECS_DIR, BRANCH.

2. Load context (from worktree):

   • Read FEATURE_SPEC (spec.md)
   • Read $WORKTREE_PATH/.specify/memory/constitution.md
   • Read IMPL_PLAN template

3. Execute plan workflow:

   • Fill Technical Context
   • Evaluate constitution gates
   • Phase 0: Generate research.md (resolve unknowns, research dependencies)
   • Phase 1: Generate data-model.md, contracts/, quickstart.md
   • Run cd $WORKTREE_PATH && .specify/scripts/bash/update-agent-context.sh claude

4. Return: Confirm plan artifacts are written to SPECS_DIR.

Phase 5: Questions Gate (MANDATORY STOP — in Worktree)

After the plan subagent completes, read ALL plan artifacts from WORKTREE_PATH and generate a comprehensive questions file. All file reads/writes in this phase use the worktree.

1. Read plan artifacts:

   • plan.md — architecture, file structure, tech decisions
   • research.md — decisions and alternatives
   • data-model.md — entities and relationships (if exists)
   • contracts/ — API specifications (if exists)
   • quickstart.md — integration scenarios (if exists)

2. Generate <feature-folder>/questions.md (inside the feature's spec folder under .specify/systems/) with this structure:

   # Implementation Questions: [Feature Name]
   
   **Generated**: [DATE]
   **Feature**: [Link to spec.md]
   **Plan**: [Link to plan.md]
   **Status**: AWAITING ANSWERS
   
   ---
   
   ## Q1: [Topic]
   
   **Context**: [Quote relevant section from plan/spec/research that raises this question]
   
   **Question**: [Specific question about an implementation decision]
   
   **Options**:
   
   | Option | Description | Implications |
   |--------|-------------|--------------|
   | A      | [First option] | [Tradeoffs, effort, risk] |
   | B      | [Second option] | [Tradeoffs, effort, risk] |
   | C      | [Third option] | [Tradeoffs, effort, risk] |
   
   **Recommended**: [A/B/C] — [Reasoning for recommendation]
   
   **Answer**: ___
   
   ---
   
   [Repeat for all questions]

3. Question quality rules:

   • Questions should be informed by the plan artifacts — technical decisions, not basic requirements
   • Each question must have at least 2 options with clear tradeoffs
   • Every question must have a recommended answer with reasoning
   • Questions should be ordered by impact (highest impact first)
   • Aim for 5-10 questions. Fewer if the feature is straightforward.
   • Do NOT ask about things that have clear best practices or obvious defaults

4. Walk through questions interactively, one at a time.

   For each question in the generated questions.md:

   a. Present the question with its full context, all options with pros/cons, and the recommended answer with clear reasoning:

   ## Question [N] of [Total]: [Topic]
   
   **Context:** [Quote from plan/spec that raises this question]
   
   **Question:** [Specific implementation decision]
   
   **Options:**
   | Option | Description | Implications |
   |--------|-------------|--------------|
   | A | [description] | [pros: ..., cons: ...] |
   | B | [description] | [pros: ..., cons: ...] |
   | C | [description] | [pros: ..., cons: ...] |
   
   **Recommended:** [Option letter] — [Reasoning]
   
   Reply with an option letter, "yes" to accept the recommendation,
   "skip" to defer, or type a custom answer.
   

   b. Wait for the user's response, then:

   • "yes" / "recommended" → use the recommended answer
   • Option letter ("A", "B", etc.) → use that option
   • "skip" → mark as **Answer:** SKIPPED — needs follow-up
   • Anything else → accept as custom answer

   c. Immediately update questions.md — fill in the **Answer:** field for that question

   d. Confirm and move to the next question: "Saved: Q[N] → [answer]. ([remaining] remaining)"

   e. If the user says "done" before all questions, mark remaining as SKIPPED

5. After all questions answered:

   a. Display a summary table of all answers b. Ask: "Would you like to change any answers? Reply with a question number or 'looks good'." c. If changes requested, re-present that question and collect a new answer d. Update Status in questions.md from "AWAITING ANSWERS" to "ANSWERED"

Phase 6: Update Plan, Then Build or Queue (in Worktree)

After answers are confirmed. All work continues in WORKTREE_PATH. The user's main working directory is never touched.

1. Update plan.md if any answers change the planned approach:

   • Launch a subagent to read answered questions and update plan.md accordingly
   • This is a targeted update, not a full rewrite

2. Copy .env from main repo to worktree if Docker-touching (scan plan.md for docker-compose.yml, Dockerfile references):

   cp <main-repo-path>/.env $WORKTREE_PATH/.env

   If Docker-touching, display warning:

   "This feature modifies Docker configuration. The worktree isolates git only — Docker operations will affect running containers."

3. Build or Queue decision point. Ask the user:

   All questions answered and spec is ready. Would you like to:

   1. Build now — launch /smith-build in the worktree for autonomous implementation
   2. Queue for later — commit spec artifacts, push, and add to the Smith queue for batch processing

   ---

   If "Queue for later" (or "2", "queue", "later"):

   a. Ask: "Priority? (critical / high / medium / low)" — default to medium if the user just says "queue" without specifying b. Commit spec artifacts in the worktree — stage and commit all files in the feature spec folder (spec.md, plan.md, questions.md, research.md, data-model.md, contracts/, checklists/):

   cd $WORKTREE_PATH && git add <feature-spec-folder>/
   cd $WORKTREE_PATH && git commit -m "docs: spec artifacts for <feature-name> — ready for queued build"

   c. Push the feature branch from the worktree:

   cd $WORKTREE_PATH && git push -u origin <branch-name>

   d. Create the queue entry in the main repo at .smith/vault/queue/<NNN-short-name>.md with this format:

   ---
   task: "Build feature: <feature-name>"
   branch: "<feature-branch-name>"
   spec_path: "<path to the feature spec folder on the feature branch>"
   primary_system: "<system ID from spec frontmatter>"
   created: "<ISO timestamp>"
   complexity: autonomous
   priority: <user's choice or medium>
   status: pending
   depends_on: []
   ---
   
   ## Context
   
   <brief description of the feature and key decisions from the questions phase>
   
   ## Artifacts on branch
   
   - spec.md — feature specification
   - plan.md — implementation plan
   - questions.md — clarification questions (all answered)
   - <list any other artifacts: research.md, data-model.md, contracts/, etc.>
   
   ## Execution Instructions
   
   Run `/smith-build` from the `<branch-name>` branch with feature dir `<spec_path>`.

   e. Clean up worktree:

   git worktree remove $WORKTREE_PATH

   f. Clear active-workflow file in the main repo (via the shipped helper, which coexists with a broad Bash(rm:*) deny rule):

   .specify/scripts/bash/clear-active-workflow.sh "$BRANCH"

   g. Confirm: "Queued: <filename> (priority: <level>, complexity: autonomous). Feature branch <branch-name> pushed with all spec artifacts. Run /smith-queue list to see pending tasks, or the 2am scheduler will pick it up automatically." h. STOP here. Do NOT launch /smith-build.

   ---

   If "Build now" (or "1", "build now", "yes", "go"):

4. Launch /smith-build in the worktree to execute the entire autonomous phase:

   • Pass WORKTREE_PATH and the feature directory path as context
   • This runs as a subagent chain (see smith-build skill)
   • Instruct the build subagent: after every Write or Edit to a .py, .js, .jsx, .ts, or .tsx file, update the touched file's .meta description layer in-context — see the "Update .meta Descriptions for Touched Methods" sub-step pattern in the /smith-bugfix skill (Phase 3.5). Touched-method-only regeneration keeps token cost bounded and preserves previously-accepted descriptions for untouched methods, per the v2 manifest contract (data-model.md §4 and spec.md C1). Failures of the helper are non-blocking — the missing descriptions are surfaced by /smith-build's PR-body Description Coverage Warnings section.
   • Wait for completion

4.5 In-context .meta description update (mid-conversation code edits). If /smith-new itself wrote or edited any source code directly (i.e. before delegating to /smith-build), apply the v3 inline Task-spawning prose from /smith-bugfix Phase 3.5 (step 3) per modified file. The flow is: discover → build-prompt → spawn Task (subagent_type=general, model=claude-haiku-4-5) → pipe JSON into describe_write.py apply --update-touched. Subscription billing via session auth — no ANTHROPIC_API_KEY. See /smith-bugfix Phase 3.5 for the full identification heuristic and prompt assembly. Skip silently if no source code was edited at this stage.

5. Display final summary to the user. Emit a chat message that starts with "Feature <name> complete. Here's the summary:" and includes the feature name and branch, files created/modified, PR link, release notes summary, and link to specs/<feature>/release.md. At the bottom, run the totals command and paste the lines it prints verbatim — do this BEFORE step 9 (clearing the active-workflow file) so the numbers are fresh. Pass the workflow's own session log via --session so totals are computed against the correct file even if the session log rolled over mid-workflow:

   # $SESSION was captured at workflow start (step 0). Fall back to the marker's
   # session_log field, then to .current-session, if it's not in scope here.
   SESSION="${SESSION:-$(cat .smith/vault/.current-session 2>/dev/null)}"
   bash "$HOME/.claude/hooks/workflow-summary.sh" --totals-only --session "$SESSION"

   The bash invocation is a required action, not an optional extra — the totals lines must appear in the chat message. If it prints n/a (no workflow invocation found) and exits non-zero, do NOT present those as real numbers — note that totals were unavailable and which session file was checked.

6. Merge PR from the main repo directory (not the worktree — avoids "main already checked out" errors): IMPORTANT: Always run gh pr merge from the primary repo directory.

   cd <main-repo-path> && gh pr merge <PR_NUMBER> --squash --delete-branch
   cd <main-repo-path> && git pull origin "$(.specify/scripts/bash/get-base-branch.sh)"

   • Squash-merge the PR to keep history clean
   • Delete the remote feature branch
   • Pull latest from the configured base branch so the local copy is up to date

7. Full workflow summary (session log only) — emitted automatically. The workflow-summary.sh Stop hook appends a "=== Workflow Summary ===" block with duration, estimated tokens, tool calls, subagent totals, and files changed to the session log file once the active-workflow file is removed (step 9 below). Do not emit the full block to the user manually — the two-line totals already surfaced in step 5 are the chat-visible version; the full block is for audit only.

8. Clean up worktree:

   git worktree remove $WORKTREE_PATH

9. Clear workflow tracking — remove the active-workflow file via the shipped helper (safe against a Bash(rm:*) deny rule):

   .specify/scripts/bash/clear-active-workflow.sh "$BRANCH"

Post-Workflow Reflection

After workflow completion (success or failure), trigger a Ledger reflection if enabled:

1. Read .smith/config.json — if ledger.auto_reflect is true (default), proceed
2. Launch a non-blocking background sub-agent using the configured reflection model (default: Haiku):
   • Pass: current session log path, .smith/vault/ledger/ path
   • The sub-agent runs the smith-reflect workflow
   • Do NOT wait for the sub-agent to complete
3. If .smith/config.json is missing or ledger.auto_reflect is false, skip silently

Post-Reflection Reconciliation Check

After reflection completes (or is skipped):

1. Read .smith/config.json — if ledger.reconcile.auto_reconcile is false, skip
2. Read .smith/vault/ledger/.meta.json — check signals against thresholds:
   • estimated_tokens > thresholds.total_tokens_max (default 30000)
   • context_budget_violations > thresholds.context_violations_threshold (default 3)
   • reinforcements_since_reconcile > thresholds.reinforcements_threshold (default 50)
3. Check minimum interval: if last_reconcile is less than minimum_hours_between_reconciles (default 6) hours ago, skip
4. If any threshold exceeded AND minimum interval has passed:
   • Launch a non-blocking background sub-agent using the configured reconcile_model (default: Haiku)
   • Pass: "Run /smith-ledger reconcile on this project"
   • Do NOT wait for the sub-agent to complete
5. If no threshold exceeded, .meta.json is missing, or config is missing, skip silently

Post-Workflow Sync (run last)

As the VERY LAST action — after the PR merge, worktree removal, marker clear, and the reflection/reconciliation launches above — Run /smith-sync from the primary repo on the default branch. This sweeps the team-shareable .smith/ artifacts (manifest, .meta describe layer, ledger, bank, agents, sessions) accumulated this session into a single chore(smith): … [skip ci] commit and pushes it to the default branch, so teammates receive the updated context.

Do NOT block on the background reflection sub-agent — this session's ledger update (written asynchronously by reflection) will be captured by the NEXT /smith-sync run. /smith-sync no-ops cleanly if there is nothing to sync.

Key Rules

• All paths must be absolute
• For single quotes in args, use escape syntax: 'I'\''m Groot'
• Worktree isolation: The worktree is created in Phase 1, before any other work. ALL file operations from Phase 3 onward happen in the worktree (WORKTREE_PATH). Never checkout the feature branch or write files in the user's main working directory. The only files written to the main repo are vault entries (.smith/vault/queue/, .smith/vault/.active-workflow). The user's current branch is never changed or checked.
• The questions gate is MANDATORY — never skip it
• If context window is getting large after the conversation phase, summarize requirements before launching subagents
