Janis Eccarius e13c9c2637 chore(claude): add YouTrack command suite
Port create-defect, create-story, estimate-issues, fix-defect,
implement-feature and split-story commands, adapted for GitOps
(kustomize build + kubectl dry-run gates, NCI routing).
implement-feature now walks subtasks, respects blocked-by, and reports
cross-project (NCS/NCWF) tasks. Ignore .claude/worktrees.

# Split Story into Subtasks in YouTrack
Split a user story into smaller, implementable subtasks. Story ID: `$ARGUMENTS`
This is the **GitOps** repo. Infrastructure subtasks route to `NCI`.
## Step 1 — Fetch Story
Call `mcp__youtrack__get_issue` with ID `$ARGUMENTS`.
Extract and display: summary, description, acceptance criteria, implementation notes.
## Step 2 — Research (if needed)
If the story involves unfamiliar manifests, charts, or constraints:
- Search repo for relevant paths (`Grep`/`Bash`); read `ARCHITECTURE.md` / `CONFIGURATION.md`.
- Render affected overlays: `kustomize build --enable-helm <path>`.
- Use `WebSearch` for Helm chart / Argo CD / Kargo / Kubernetes API references.
- Do NOT guess. Surface findings before proposing splits.
## Step 3 — Propose Split
Analyse the story and propose a set of subtasks. Rules:
- Each subtask = one unit of work, completable independently or in sequence.
- No subtask should exceed ~2 days of work.
- Name subtasks in imperative mood (e.g. "Add region kustomization", "Wire Argo CD app + sync wave", "Add cert-manager Certificate").
- Cover the full scope of the parent story — no gaps.
Show proposed subtask list to user (titles only) and ask:
**Use `AskUserQuestion` tool:**
- Does the split look right?
- Any subtasks to add, remove, or merge?
- Should any subtask be assigned to a specific person?
Incorporate feedback. Repeat until user approves the list.
## Step 4 — Draft Each Subtask
For each approved subtask, compose description using this template:
```
[Brief description of what needs to be done for this subtask.]
Steps / Tasks
- Task 1
- Task 2
- Task 3
Definition of Done
What must be true for this subtask to be considered complete:
- Manifests / overlays updated
- `kustomize build` renders clean and `kubectl apply --dry-run=client` passes
- Reviewed and merged (Argo CD syncs healthy if applicable)
```
Rules:
- Steps/Tasks: concrete, ordered where order matters.
- Definition of Done: adjust per subtask — not all subtasks need the same criteria (e.g. a research spike has different DoD than a manifest change).
- Keep description short — one paragraph max.
## Step 5 — Determine Project per Subtask
Assign each subtask's project based on its content — do **not** inherit blindly from parent:
- Infrastructure (Kubernetes, Argo CD, Kargo, pipelines, CI/CD, DB setup) → `NCI`
- Backend code (game engine, bots, API, services, coordinator) → `NCS`
- Frontend code (UI, UX, web app) → `NCWF`
If a subtask's project is ambiguous, ask the user before creating it.
## Step 6 — Create Subtasks
For each subtask call `mcp__youtrack__create_issue` with:
- `project`: from Step 5
- `summary`: subtask title (≤72 chars, sentence case)
- `description`: full formatted description from Step 4 (Markdown)
- `type`: `Task`
Then call `mcp__youtrack__link_issues` to link each created subtask to `$ARGUMENTS` with relation `subtask of`.
## Step 6b — Inter-Subtask Links
If subtasks must be done in sequence (one depends on output of another), add ordering links:
- For each dependency pair call `mcp__youtrack__link_issues` with relation `is blocked by` (subtask B is blocked by subtask A).
Ask the user to confirm sequencing before adding these links:
> Do any subtasks have ordering dependencies? (e.g. "Add region kustomization must come before Wire Argo CD app")
## Step 6c — External Links
Scan `$ARGUMENTS` description and implementation notes for any referenced issue IDs not already linked. For each:
| Situation | Relation |
|-----------|---------|
| Parent story blocks another epic/story | `blocks` |
| Story depends on another epic completing | `is blocked by` |
| Related story in same domain | `relates to` |
| This story duplicates or supersedes | `duplicates` |
Suggest links to the user and call `mcp__youtrack__link_issues` on confirmation.
## Step 7 — Report
List all created subtask IDs and summaries.
List all links created (subtask-of, blocking chains, external).
Display parent story link.
Ask if any subtask needs further splitting.
