+# Create Defect in YouTrack
+
+Automated defect creation workflow. Topic/hint: `$ARGUMENTS`
+
+## Step 1 — Gather Context
+
+Use `AskUserQuestion` tool to ask the user (max 4 questions at once):
+
+1. **Component** — Where does the bug occur? (e.g. move generation, FEN parsing, castling, UI, API)
+2. **What breaks** — What is the actual (broken) behavior?
+3. **Expected** — What should happen instead?
+4. **Reproducibility** — Is it always reproducible? Any known trigger conditions?
+
+If `$ARGUMENTS` already answers some of these, skip those questions.
+
+## Step 2 — Research (if needed)
+
+If the bug involves domain logic or rules:
+- Search repo for relevant code (`Grep`/`Bash`).
+- Check test files for existing coverage of the broken area.
+- Do NOT guess at root cause. Surface findings before drafting.
+
+## Step 3 — Draft Defect
+
+Compose the full defect report using this template:
+
+```
+Summary
+
+[One-sentence description of what is broken.]
+
+
+Steps to Reproduce
+
+1. Step one
+2. Step two
+3. Step three
+
+
+Expected Behavior
+
+[What should happen.]
+
+
+Actual Behavior
+
+[What actually happens.]
+
+
+Environment / Notes
+
+[Any relevant context: FEN positions, game conditions, config, browser, OS — only if applicable.]
+```
+
+Rules:
+- Steps must be minimal and reproducible.
+- Expected vs actual: concrete and unambiguous.
+- Omit "Environment / Notes" section if not relevant.
+
+## Step 4 — Clarify
+
+Show the draft to the user.
+**Use `AskUserQuestion` tool to ask:**
+- Are steps to reproduce complete and accurate?
+- Severity: Blocker / Critical / Major / Minor / Trivial?
+- Any related tickets or recent changes to link?
+
+Incorporate feedback. Repeat until user approves.
+
+## Step 5 — Determine Project
+
+- Frontend / UI / UX → project: `NCWF`
+- Backend / coordinator / systems / bot / engine → project: `NCS`
+
+If ambiguous, ask the user.
+
+## Step 6 — Create Issue
+
+Call `mcp__youtrack__create_issue` with:
+- `project`: determined in Step 5
+- `summary`: concise title describing what is broken (≤72 chars, sentence case)
+- `description`: full formatted defect report from Step 3 (Markdown)
+- `type`: `Bug`
+
+## Step 7 — Report
+
+Display the created issue ID and URL.
+Ask if a linked investigation or fix task is needed.

+# Create User Story in YouTrack
+
+Automated user-story creation workflow. Topic/hint: `$ARGUMENTS`
+
+## Step 1 — Gather Context
+
+Use `AskUserQuestion` tool to ask the user (max 4 questions at once):
+
+1. **Domain** — Is this frontend (UI/UX) or backend/coordinator/systems work?
+2. **User type** — Who is the actor? (e.g. player, admin, bot, system)
+3. **Action** — What should the user be able to do?
+4. **Goal/value** — Why? What outcome does it enable?
+
+If `$ARGUMENTS` already answers some of these, skip those questions.
+
+## Step 2 — Research (if needed)
+
+If the topic involves unfamiliar domain logic, game rules, or technical constraints:
+- Search the repo for relevant code (use `Grep`/`Bash` to find related files).
+- Use `WebSearch` if the topic involves external standards or protocols.
+- Do NOT guess. Surface findings before drafting.
+
+## Step 3 — Draft Story
+
+Compose the full story using this template:
+
+```
+As a [type of user]
+I want to [perform an action]
+So that [achieve a goal or value]
+
+
+Description
+
+[Additional context or business logic for this story.]
+
+
+Acceptance Criteria
+
+[List the specific, measurable criteria that define when this story is done:]
+
+- Criterion 1
+- Criterion 2
+- Criterion 3
+
+
+Implementation Notes
+
+[Technical notes, design references, or constraints.]
+```
+
+Rules:
+- User story line: plain English, present tense, from user's perspective.
+- Acceptance criteria: testable, unambiguous, one condition each.
+- Implementation notes: optional — only include if there are known constraints, related tickets, or design refs.
+
+## Step 4 — Clarify Acceptance Criteria
+
+Show the draft to the user.
+**Use `AskUserQuestion` tool to ask:**
+- Are the acceptance criteria complete and correct?
+- Any implementation constraints to add?
+- Priority (if known)?
+
+Incorporate feedback. Repeat until user approves.
+
+## Step 5 — Determine Project
+
+> **Project routing rules (always apply these):**
+> - Backend code (game engine, bots, API, services, coordinator) → `NCS`
+> - Frontend code (UI, UX, web app) → `NCWF`
+> - Infrastructure (Kubernetes, pipelines, CI/CD, DB setup, cloud infra) → `NCI`
+> - If ambiguous, ask the user.
+
+- Frontend / UI / UX → project: `NCWF`
+- Backend / coordinator / systems / bot / engine → project: `NCS`
+- Kubernetes, pipelines, CI/CD, DB setup, infrastructure → project: `NCI`
+
+If still ambiguous, ask the user.
+
+## Step 6 — Create Issue
+
+Call `mcp__youtrack__create_issue` with:
+- `project`: determined in Step 5
+- `summary`: concise title derived from the "I want to" clause (≤72 chars, sentence case)
+- `description`: full formatted story from Step 3 (Markdown)
+- `type`: `Feature` (or `Task` if purely technical with no user-facing value)
+
+## Step 7 — Link Issues
+
+After creation, **automatically** ask the user (use `AskUserQuestion` if interactive, otherwise infer from context):
+
+> Are there related issues to link? (skip if none)
+
+Collect any issue IDs the user mentions. For each, determine the correct relation and call `mcp__youtrack__link_issues`:
+
+| Situation | Relation to use |
+|-----------|----------------|
+| This story must be done before another | `blocks` |
+| Another story must be done before this | `is blocked by` |
+| Stories share domain or are related | `relates to` |
+| This is a child of an epic/story | `subtask of` |
+| This is a parent grouping subtasks | `parent for` |
+| This depends on another ticket's output | `depends on` |
+
+If the user mentions an issue in the story description or implementation notes (e.g. "see NCS-42", "after NCS-12 is done"), auto-detect and suggest linking it — confirm before creating the link.
+
+## Step 8 — Report
+
+Display the created issue ID and URL.
+List any links created (relation type + linked issue ID).
+Ask if a linked sub-task or implementation ticket is needed.

+# Estimate Issue Time in YouTrack
+
+Sprint planning time estimator. Issue ID or empty for full current sprint: `$ARGUMENTS`
+
+## Step 1 — Determine Scope
+
+**Single-issue mode** (`$ARGUMENTS` set):
+- Call `mcp__youtrack__get_issue` on `$ARGUMENTS`.
+- Proceed with that issue only.
+
+**Sprint mode** (`$ARGUMENTS` empty):
+- Call `mcp__youtrack__search_issues` with query `project: NCS Sprints: {current sprint} #Unresolved`.
+- If query returns 0 results, use `AskUserQuestion` to ask for the sprint name, then retry with `project: NCS Sprints: {name}`.
+- Collect all returned issues.
+
+## Step 2 — Build Issue Tree
+
+For each top-level issue from Step 1:
+1. Fetch full details via `mcp__youtrack__get_issue`: summary, description, acceptance criteria, Type, existing `Zeitschätzung`, linked issues.
+2. Identify subtasks from links with relation `subtask of` (i.e. issues where the fetched issue is the parent).
+3. Recursively fetch subtasks until all leaves are known.
+4. Group into tree: Epic → Story → Task/Subtask.
+
+**Leaf node** = issue with no subtask children.
+**Parent node** = issue that has at least one subtask child.
+
+## Step 3 — Estimate Leaf Nodes
+
+For each leaf node:
+1. Read: summary, description, acceptance criteria, implementation notes.
+2. If scope is unclear, search codebase (`Grep`/`Bash`) for related files to gauge complexity.
+3. Assign estimate using this scale:
+
+| Size | Criteria | Estimate |
+|------|----------|----------|
+| Trivial | Config change, rename, 1-file tweak | 30m |
+| Small | 1–3 files, clear scope, no unknowns | 1h–2h |
+| Medium | 3–6 files, some design needed | 3h–5h |
+| Large | 6+ files, cross-module, non-trivial design | 1d–2d |
+| XL | New subsystem, research spike, major refactor | 3d–5d |
+
+4. Record: estimate + one-line reasoning.
+5. Skip leaf if it already has `Zeitschätzung` set — note it as pre-estimated.
+
+## Step 4 — Roll Up for Display
+
+YouTrack auto-sums `Zeitschätzung` from subtasks up to parents — **do not write estimates to parent nodes**.
+
+Compute display-only rolled-up totals:
+- Parent total = sum of all descendant leaf estimates (including pre-estimated ones).
+- Flag any branch where some leaves are missing estimates (partial roll-up).
+
+## Step 5 — Show Summary + Confirm
+
+Display full tree with estimates. Format:
+
+```
+Epic  NCS-10: Castling overhaul             [4h 30m]  ← rolled up
+  Story NCS-11: Validate castling rights    [2h 30m]  ← rolled up
+    Task  NCS-12: Fix RuleSet check          1h 30m   ← leaf (new)
+    Task  NCS-13: Add regression tests       1h       ← leaf (new)
+  Story NCS-14: UI feedback for castling    [2h]      ← rolled up
+    Task  NCS-15: Highlight invalid squares  2h       ← leaf (pre-set, skipped)
+```
+
+Legend: `[X]` = display-only roll-up (not written). Plain = will be written to YouTrack.
+
+If sprint mode, show grand total at bottom:
+```
+Sprint total: Xd Yh Zm  (N issues, M leaves to update)
+```
+
+**Use `AskUserQuestion` tool:**
+- Does the breakdown look right?
+- Any estimates to adjust before writing to YouTrack?
+
+Incorporate all feedback before proceeding.
+
+## Step 6 — Write Estimates
+
+On user approval, write estimates **only to leaf nodes** (bottom-up order):
+- For each leaf with a new estimate, call `mcp__youtrack__update_issue` with field `Zeitschätzung` = approved estimate.
+- YouTrack period format: `"30m"`, `"1h 30m"`, `"1d"`, `"2d 4h"`.
+- Skip leaves already pre-estimated.
+
+## Step 7 — Report
+
+List all updated issues with set estimates.
+Show final rolled-up totals per Epic/Story (read back from YouTrack via `mcp__youtrack__get_issue` if needed).
+In sprint mode, show total sprint estimate.

+# Fix Defect from YouTrack
+
+Automated defect-fix workflow. Ticket ID: `$ARGUMENTS`
+
+## Step 1 — Fetch Ticket
+
+Call `mcp__youtrack__get_issue` with ID `$ARGUMENTS`.
+Extract and display: summary, description, steps to reproduce, Priority, Subsystem.
+
+## Step 2 — Create Worktree
+
+Derive branch name from ticket:
+- `type` from YouTrack issue type: `bug` → `fix`, `feature`/`task` → `feat`, `refactor` → `refactor`, else `chore`
+- `scope` from affected module/component (kebab-case, omit if unclear)
+- `description` from ticket summary: lowercase, kebab-case, max 40 chars, drop articles
+
+Branch format: `<type>/<ticket-id>-<description>`
+Example: `fix/NOW-123-castling-validation-failure`
+
+Call `EnterWorktree` with that branch name.
+All subsequent file work happens inside this worktree.
+
+## Step 3 — Identify Root Cause (read-only)
+
+1. Run `./compile` — capture all errors and warnings.
+2. Run `./test` — capture all failures.
+3. Spawn `cavecrew-investigator` with: ticket description + compile/test output → locate root cause (files, line numbers, what's wrong).
+4. **If anything is ambiguous (reproduction unclear, scope uncertain, conflicting signals), use `AskUserQuestion` tool to ask — max 4 questions at once.**
+5. **Report findings to user. No file writes yet. Wait for acknowledgement before continuing.**
+
+## Step 3b — Complexity Assessment + Subtasks
+
+After root cause confirmed, assess scope:
+
+**Simple** (1–2 files, single concern, < 1 hour estimated): proceed directly to Step 4.
+
+**Complex** (3+ files, multiple concerns, or estimated > 1 hour): create subtasks before coding.
+
+To create subtasks:
+1. Break fix into discrete, independently-completable tasks (e.g. "Fix validation in RuleSet", "Add regression test for castling edge case", "Update FenParser to handle X").
+2. For each subtask call `mcp__youtrack__create_issue` with:
+   - `project`: based on subtask content — do **not** inherit from parent. Backend code → `NCS`; frontend/UI → `NCWF`; Kubernetes/pipelines/CI-CD/DB setup/infrastructure → `NCI`. If ambiguous, ask user.
+   - `summary`: concise action-oriented title
+   - `type`: `Task`
+   - `description`: what to do and why
+3. Call `mcp__youtrack__link_issues` to link each subtask to `$ARGUMENTS` with relation `subtask of`.
+4. Check if the ticket description or comments mention other issue IDs. For each mentioned ID, suggest a link and confirm with user:
+   - Fix depends on another fix finishing first → `is blocked by`
+   - This fix blocks another ticket → `blocks`
+   - Logically related but independent → `relates to`
+5. List created subtask IDs and any additional links to user.
+
+Then proceed to Step 4, implementing subtasks in order.
+
+## Step 4 — Fix
+
+1. Implement fix (use `scala-implementer` agent for non-trivial changes; inline edits for small ones).
+2. Run `./compile` — must be green.
+3. Run `./test` — must be green.
+4. Run `./gradlew spotlessScalaApply` — **blocking, foreground only**. Wait for completion before continuing.
+5. Run `./lint` — **blocking, foreground only** (never `run_in_background`). Wait for exit code 0. Must be green.
+   - If lint fails, fix all issues and re-run until exit code 0.
+   - **Do NOT proceed to Step 5 until `./lint` has completed and returned exit code 0.**
+If any step fails, iterate until all pass.
+
+## Step 5 — Review
+
+Spawn `cavecrew-reviewer` on the full diff.
+Display findings grouped by severity.
+
+## Step 5b — Apply Review Findings
+
+If the review produced any findings (any severity):
+1. Implement all agreed fixes.
+2. Run `./compile` — must be green.
+3. Run `./test` — must be green.
+4. Run `./gradlew spotlessScalaApply` — **blocking, foreground only**. Wait for completion.
+5. Run `./lint` — **blocking, foreground only**. Wait for exit code 0.
+   - If lint fails, fix all issues and re-run until exit code 0.
+6. Re-spawn `cavecrew-reviewer` on the updated diff to confirm all findings are resolved.
+
+Repeat until review is clean or user explicitly accepts remaining findings.
+
+## Step 6 — Confirm + Push
+
+Show summary: ticket, branch, files changed, review findings.
+**Use `AskUserQuestion` tool to ask for explicit approval before pushing.** Include any open questions about commit message scope or body if unclear.
+
+On approval, commit following Conventional Commits:
+
+```
+<type>(<scope>): <short description, imperative, ≤50 chars>
+
+<optional body: what changed and why, wrap at 72 chars>
+
+Closes $ARGUMENTS
+https://knockoutwhist.youtrack.cloud/issue/$ARGUMENTS
+```
+
+- `type`: same as branch type (`fix`, `feat`, `refactor`, `chore`, etc.)
+- `scope`: affected module (`core`, `rule`, `api`, `bot`, `io`)
+- Subject: imperative mood, no period, lowercase
+- Footer `Closes $ARGUMENTS` and ticket URL always present
+
+Push branch to remote.
+
+## Step 7 — Comment on Ticket
+
+After successful push, call `mcp__youtrack__add_issue_comment` on `$ARGUMENTS` with:
+
+```
+Branch `<branch-name>` pushed.
+
+<one-sentence summary of what was changed and why>
+
+Files changed:
+- <file1>
+- <file2>
+```
+
+## Step 7b — Additional Links
+
+After commenting, ask the user if `$ARGUMENTS` should be linked to any other issues not already linked:
+
+| Situation | Relation |
+|-----------|---------|
+| This fix blocks another open ticket | `blocks` |
+| Another ticket must ship first | `is blocked by` |
+| Related defect or story | `relates to` |
+| Duplicate of another defect | `duplicates` |
+
+Scan the ticket description and comments for any issue IDs that were mentioned but not yet linked. Suggest those automatically.
+
+Call `mcp__youtrack__link_issues` for each confirmed link.
+
+## Step 8 — Cleanup
+
+Call `ExitWorktree` with `discard_changes: true` to delete the worktree.
+(Branch was pushed in step 6 — commits are safe on remote; `discard_changes: true` bypasses the local-ahead guard.)
+Report: branch pushed, ticket commented, links created, worktree deleted, done.

+3. Spawn `cavecrew-investigator` with: ticket description + acceptance criteria → locate affected files, relevant types/interfaces, entry points, integration touch-points.
+4. **If anything is ambiguous (scope unclear, acceptance criteria missing, design decisions needed), use `AskUserQuestion` tool to ask — max 4 questions at once.**
+5. **Report plan to user: what will be added/changed, which files, which modules. No file writes yet. Wait for acknowledgement before continuing.**

+# Split Story into Subtasks in YouTrack
+
+Split a user story into smaller, implementable subtasks. Story ID: `$ARGUMENTS`
+
+## Step 1 — Fetch Story
+
+Call `mcp__youtrack__get_issue` with ID `$ARGUMENTS`.
+Extract and display: summary, description, acceptance criteria, implementation notes.
+
+## Step 2 — Research (if needed)
+
+If the story involves unfamiliar domain logic or technical constraints:
+- Search repo for relevant code (`Grep`/`Bash`).
+- Use `WebSearch` for external standards or protocols.
+- 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. "Implement move validation endpoint").
+- 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:
+
+- Code implemented
+- Tests passed
+- Reviewed and merged
+```
+
+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 an implementation task).
+- 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:
+
+- Backend code (game engine, bots, API, services, coordinator) → `NCS`
+- Frontend code (UI, UX, web app) → `NCWF`
+- Kubernetes, pipelines, CI/CD, DB setup, infrastructure → `NCI`
+
+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 `$ARGUMENTS` with relation `subtask of`.
+
+## Step 6b — Inter-Subtask Links
+
+If subtasks must be done in sequence (one depends on output of another), add ordering links:
+- For each dependency pair call `mcp__youtrack__link_issues` with relation `is blocked by` (subtask B is blocked by subtask A).
+
+Ask the user to confirm sequencing before adding these links:
+
+> Do any subtasks have ordering dependencies? (e.g. "Implement X must come before Add tests for X")
+
+## Step 6c — External Links
+
+Scan `$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.

+    Game moves flow through the existing board and bot endpoints — this module
+    handles pairings, standings, and lifecycle only.
+
+    ## Streaming
+    Endpoints marked **NDJSON** return newline-delimited JSON objects
+    (`application/x-ndjson`). Each line is one complete JSON object. The
+    connection stays open until the tournament or round ends.
+
+    ## Bot flow
+    ```
+    POST /api/tournament                       # create
+    POST /api/tournament/{id}/join             # each bot joins
+    POST /api/tournament/{id}/start            # director starts
