Startup Upgrade Check

Run this at most once per active agent session before the first Spec Kitty command workflow. If you already ran spec-kitty upgrade --agent-check --json in this session, reuse that result and skip this block. Do not run or announce an upgrade check again for later Spec Kitty commands in the same session. Otherwise, before continuing, run:

spec-kitty upgrade --agent-check --json

If JSON action is none, continue. If action is auto_upgrade, run upgrade_command before continuing. If it fails, tell the user and continue with the current Spec Kitty version. If action is guidance, show upgrade_note briefly, then continue. If action is prompt, ask the user with the host-native question UI when available:

Spec Kitty {latest_version} is available. You are on {installed_version}. Upgrade now?

Use these choices:

1. Upgrade now (recommended) - record upgrade_now, run upgrade_command, then continue.
2. Always keep me up to date - record always, run upgrade_command, then continue.
3. Not now - record not_now, then continue.
4. Never ask again - record never_ask, then continue.

Record the selected choice before continuing:

spec-kitty upgrade --agent-choice <upgrade_now|always|not_now|never_ask> --agent-latest <latest_version> --json

If no host-native question UI is available, present the same four choices in plain text and wait for the user. In non-interactive hosts, choose not_now and continue.

/spec-kitty.tasks-packages - Generate Work Package Files

Version: 3.2.0

Purpose

Generate individual tasks/WP*.md prompt files from the manifest in wps.yaml. This step reads wps.yaml (written in tasks-outline), updates it with per-WP details, then generates the WP prompt files.

This step assumes wps.yaml already exists with complete WP definitions.

---

📍 WORKING DIRECTORY: Stay in the repository root checkout

IMPORTANT: This step works in the repository root checkout. NO worktrees created.

In repos with multiple missions, always pass --mission <handle> to every spec-kitty command. The <handle> can be the mission's mission_id (ULID), mid8 (first 8 chars of the ULID), or mission_slug. The resolver disambiguates by mission_id and returns a structured MISSION_AMBIGUOUS_SELECTOR error on ambiguity — there is no silent fallback.

User Input

The content of the user's message that invoked this skill (everything after the skill invocation token, e.g. after /spec-kitty.<command> or $spec-kitty.<command>) is the User Input referenced elsewhere in these instructions.

You MUST consider this user input before proceeding (if not empty).

Steps

1. Setup

Run:

spec-kitty agent context resolve --action tasks_packages --mission <mission-slug> --json

Then execute the returned check_prerequisites command and capture feature_dir. All paths must be absolute.

2. Load wps.yaml

Read feature_dir/wps.yaml. This is the manifest written in the previous step. Each entry defines a WP with its id, title, dependencies, and partial metadata.

Parse all work package entries. The YAML structure is:

work_packages:
  - id: WP01
    title: "..."
    dependencies: [...]   # may be present (authoritative) or absent
    owned_files: [...]    # may be absent — fill in this step
    requirement_refs: [...] # may be absent — fill in this step
    subtasks: [...]
    prompt_file: null     # fill in this step

3. Generate Prompt Files in Parallel

Parse all WP definitions from wps.yaml. Each WP prompt file is independent — dispatch one sub-agent per WP in a single message so they run concurrently rather than generating all WP content in one serial response.

CRITICAL PATH RULE: All WP files MUST be created in a FLAT feature_dir/tasks/ directory, NOT in subdirectories!

• Correct: feature_dir/tasks/WPxx-slug.md (flat, no subdirectories)
• WRONG: feature_dir/tasks/planned/, feature_dir/tasks/doing/, or ANY status subdirectories

Batching for large missions: If there are more than 6 WPs, dispatch in groups of 4. Send all agents in a group in one message, wait for all to complete, then start the next group.

Sub-agent prompt (send one per WP, all dispatched simultaneously in one message):

---

You are writing a single Work Package prompt file for the spec-kitty planning pipeline. Write exactly one file and return the filename and final line count.

Feature directory: {feature_dir} (absolute path) Write to: {feature_dir}/tasks/{wp_id}-{slug}.md

Work Package (from wps.yaml):

• id: {wp_id}
• title: {title}
• dependencies: {dependencies}
• owned_files: {owned_files}
• execution_mode: derive from owned_files (planning_artifact for kitty-specs/docs-only WPs, otherwise code_change)
• requirement_refs: {requirement_refs}
• subtasks: {subtasks}

Read for context (all from feature_dir):

• plan.md (required — tech architecture, stack)
• spec.md (required — user stories, acceptance criteria)
• data-model.md, research.md (read if present)

Write the WP prompt file with this structure:

Frontmatter:

---
work_package_id: "{wp_id}"
title: "{title}"
dependencies: {dependencies}
requirement_refs: {requirement_refs}
subtasks: {subtasks}
owned_files: {owned_files}
authoritative_surface: "{longest common path prefix of owned_files}"
execution_mode: "{execution_mode}"
agent_profile: ""  # filled in Step 4a — profile identifier (e.g., implementer-ivan)
role: ""           # filled in Step 4a — role within the profile (e.g., "implementer")
agent: ""          # filled in Step 4a — CLI agent identifier (claude, codex, copilot, etc.)
model: ""          # filled in Step 4a — model identifier (e.g., claude-sonnet-4-6), optional
---

IMPORTANT — plan_concern_refs lives in wps.yaml only. Do NOT copy plan_concern_refs into WP prompt frontmatter. WPMetadata uses extra="forbid", so any WP prompt file with plan_concern_refs in its frontmatter will cause finalize-tasks --validate-only to raise a ValidationError.

Body sections (in order): 0. ## ⚡ Do This First: Load Agent Profile — REQUIRED. Must be the first section after the H1 title, before Objective. Instructs the implementing agent to load the assigned profile via /ad-hoc-profile-load before reading anything else. Use this exact structure, substituting frontmatter values:

## ⚡ Do This First: Load Agent Profile

Use the `/ad-hoc-profile-load` skill to load the agent profile specified in the frontmatter, and behave according to its guidance before parsing the rest of this prompt.

- **Profile**: `{agent_profile}`
- **Role**: `{role}`
- **Agent/tool**: `{agent}`

If no profile is specified, run `spec-kitty agent profile list` and select the best match for this work package's `task_type` and `authoritative_surface`.

---

1. ## Objective — 1–3 sentence goal
2. ## Context — why this WP exists, what depends on it, key design decisions from plan.md
3. ### Subtask {T-id}: {name} — one section per subtask, ~60 lines each:
   • Purpose: what this subtask accomplishes
   • Steps: numbered, with specific file paths and implementation details
   • Files: what to create/modify, approximate size
   • Validation: how to verify it works
4. ## Definition of Done — verifiable checklist covering all subtasks
5. ## Risks — known risks and mitigations
6. ## Reviewer Guidance — what reviewers should focus on

Include the implementation command: spec-kitty agent action implement {wp_id} --agent <name>

Sizing: target 200–500 lines (3–7 subtasks), maximum 700 lines (10 subtasks). If >700 lines would be needed: write the file anyway but add a > NOTE: This WP should be split callout at the top.

---

After all sub-agents confirm completion, proceed to Step 4.

Fallback — if your host does not support sub-agents: Generate all WP files sequentially and issue all Write tool calls in a single batched response.

Do NOT update wps.yaml during sub-agent dispatch — collect all confirmations, then update once in Step 4.

4. Update wps.yaml With Per-WP Details

After all sub-agents have confirmed completion, update wps.yaml once with all per-WP details collected from sub-agent results: owned_files, requirement_refs, subtasks, and prompt_file for every WP. Write the updated wps.yaml in a single write.

Critical rule: Do NOT modify a dependencies field that is already present in wps.yaml — even if it is empty ([]). It is authoritative. Only populate dependencies for entries where the key is absent from wps.yaml.

Example of a fully-populated entry after this step:

- id: WP02
  title: "Build API"
  dependencies:
    - WP01
  owned_files:
    - "src/api/**"
  requirement_refs:
    - FR-001
    - NFR-001
  plan_concern_refs:
    - IC-02
  subtasks:
    - T001
    - T002
  prompt_file: "tasks/WP02-build-api.md"

The frontmatter in each WP prompt file MUST include a dependencies field:

---
work_package_id: "WP02"
title: "Build API"
dependencies: ["WP01"]  # From wps.yaml
requirement_refs: ["FR-001", "NFR-001"]  # From wps.yaml requirement_refs
subtasks: ["T001", "T002"]
owned_files: ["src/api/**"]
authoritative_surface: "src/api/"
execution_mode: "code_change"
---

Note: plan_concern_refs is a wps.yaml-only field. It must NOT appear in WP prompt frontmatter — WPMetadata (extra="forbid") will reject any WP file that includes it.

Include the correct implementation command:

• spec-kitty agent action implement WP01 --agent <name>
• spec-kitty agent action implement WP02 --agent <name>

finalize_tasks computes execution lanes from dependencies and write ownership. Agents never choose a base branch manually.

Ownership rules:

• owned_files: List of glob patterns for files this WP touches — no two WPs may overlap.
• authoritative_surface: Path prefix that must be a prefix of at least one owned_files entry.
• execution_mode: "code_change" for source code changes, "planning_artifact" for kitty-specs docs.
• Agents working on a WP should prefer to stay within their owned_files list; a small, well-justified out-of-map edit is acceptable when recorded with a one-line rationale (the no-overlap rule above is the real guard against parallel-WP collisions).

4a. Assign Agent Profiles

After all WP files are written and wps.yaml is updated, review all available doctrine-provided and user-created agent profiles and assign the most relevant profile to each work package.

List available profiles:

spec-kitty agent profile list --json

If this command is unavailable, look for profiles under src/doctrine/agent_profiles/built-in/ and any user-defined profiles in .kittify/agent_profiles/ or equivalent.

For each WP, select the best-matching profile based on task_type, authoritative_surface, owned_files, and subtask content. Then update the WP prompt file's frontmatter in place with:

• agent_profile: the profile identifier (e.g., "implementer-ivan", "architect-alphonso", "curator-carla")
• role: the role within the profile (e.g., "implementer", "reviewer")
• agent: the CLI agent/tool identifier (e.g., "claude", "codex", "copilot")
• model: the model identifier (optional, e.g., "claude-sonnet-4-6")

Also update the corresponding entry in wps.yaml with these fields.

5. Self-Check

After all sub-agents complete, verify each generated prompt:

• ## ⚡ Do This First: Load Agent Profile is the first body section (before Objective)? ✓ ❌ if missing
• Subtask count: 3-7? ✓ | 8-10? ⚠️ | 11+? ❌ needs splitting
• Estimated lines: 200-500? ✓ | 500-700? ⚠️ | 700+? ❌ needs splitting
• agent_profile, role, agent set for every WP? ✓
• owned_files glob patterns non-overlapping across all WPs? ✓
• Can implement in one session? ✓ | Multiple sessions needed? ❌ needs splitting

Output

After completing this step:

• feature_dir/tasks/WP*.md prompt files exist for all work packages
• Each has proper frontmatter with work_package_id, dependencies, owned_files, authoritative_surface, execution_mode
• feature_dir/wps.yaml is fully populated: all owned_files, requirement_refs, subtasks, and prompt_file fields are set

Next step: spec-kitty next --agent <name> will advance to finalization.

Prompt Quality Guidelines

Good prompt (~60 lines per subtask):

### Subtask T001: Implement User Login Endpoint

**Purpose**: Create POST /api/auth/login endpoint that validates credentials and returns JWT token.

**Steps**:
1. Create endpoint handler in `src/api/auth.py`:
   - Route: POST /api/auth/login
   - Request body: `{email: string, password: string}`
   - Response: `{token: string, user: UserProfile}` on success
   - Error codes: 400, 401, 429

2. Implement credential validation:
   - Hash password with bcrypt
   - Use constant-time comparison

**Files**: `src/api/auth.py` (new, ~80 lines)
**Validation**: Valid credentials return 200 with token

Bad prompt (~20 lines per subtask):

### T001: Add auth
Steps: Create endpoint. Add validation. Test it.
