By name: use-youtrack description: > General-purpose YouTrack operations for the kotlinx-rpc project (KRPC). Use this skill whenever the user wants to search, read, update, comment on, link, tag, or otherwise interact with existing YouTrack issues — anything that isn't creating a brand new issue. Also use it when the user asks about issue status, sprint progress, who's working on what, backlog queries, or wants to browse/filter issues. Trigger this even if the user doesn't say "YouTrack" explicitly — if they mention a KRPC-### issue ID, ask about tickets, want to check on an issue, update a status, or log work, this is the right skill. Do NOT use this skill for creating new issues — use file-youtrack-issue instead.
YouTrack Operations for kotlinx-rpc (KRPC)
General-purpose skill for interacting with the KRPC YouTrack project.
Project key: KRPC | URL: https://youtrack.jetbrains.com/issue/KRPC-*
For creating new issues, use the file-youtrack-issue skill instead.
Agent workflow override
When this skill is invoked from the fix-issue skill (autonomous issue-fixing workflow),
all YouTrack operations must use the agent identity instead of the user's:
- MCP server:
youtrack-agent(notyoutrack) - REST API token:
$YOUTRACK_AGENT_TOKEN(not$YOUTRACK_TOKEN)
The fix-issue skill's Authentication section has full details. Outside of fix-issue,
the defaults below apply.
Tools Available
Use mcp__youtrack__* MCP tools for standard operations. When MCP tools lack a capability
(bulk updates, custom queries, attachment management, etc.), fall back to the YouTrack REST
API via YOUTRACK_TOKEN:
curl -s -H "Authorization: Bearer $YOUTRACK_TOKEN" \
"https://youtrack.jetbrains.com/api/<endpoint>?fields=<fields>"
REST API base: https://youtrack.jetbrains.com/api
Docs: YouTrack REST API
Searching Issues
Read references/query-syntax.md for the full query syntax reference and common search
patterns (sprint work, backlog, recently closed, etc.).
Key point: YouTrack has no semantic search — always run multiple queries with different keywords to get good coverage.
Reading Issues
Use mcp__youtrack__get_issue with the issue ID (e.g., KRPC-531). This returns:
- Summary, description, reporter, timestamps
- Custom fields (Type, State, Priority, Scope, Assignee, Target Release, Planning Period)
- Recent comments (configurable count via
recentCommentsCount) - Tags, votes, linked issue counts, attachments
For full comment history, use mcp__youtrack__get_issue_comments.
Updating Issues
Read references/update-operations.md for the full reference on changing fields, assignees,
tags, comments, links, and logging work.
Key rules:
Scopemust be a JSON array, even for a single value- Multiline text fields need actual newlines, not literal
\nescape sequences - Always add the
Vibe-reporttag alongside any other tags the user requests
KRPC Project Reference
For full field definitions (scopes with determination logic, types, priorities, tags,
optional fields, team members), read
file-youtrack-issue/references/krpc-fields.md (relative to .claude/skills/).

Knowledge Base Articles
YouTrack also hosts articles (wiki-like docs). Use:
mcp__youtrack__search_articles— find articles by keywordmcp__youtrack__get_article— read a specific articlemcp__youtrack__create_article/mcp__youtrack__update_article— manage articles
Important Terminology
kRPC and gRPC are protocols, not transports. This matters in issue descriptions, comments, and when choosing scopes. kRPC is the custom RPC protocol; gRPC is HTTP/2 + Protocol Buffers. Both support multiple serialization formats.
