File Youtrack Issue Agent Skill

Filing YouTrack Issues for kotlinx-rpc (KRPC)

This skill guides you through creating well-formed issues in the KRPC YouTrack project.

The project key is KRPC and issues are tracked at https://youtrack.jetbrains.com/issue/KRPC-*.

Important Terminology

kRPC and gRPC are protocols, not transports. This distinction matters throughout the

project. kRPC is the custom RPC protocol; gRPC is the HTTP/2 + Protocol Buffers RPC protocol.

Always refer to them as protocols in issue descriptions and summaries.

Before You Start

Use the mcp__youtrack__* MCP tools for standard operations (create, search, update, tag).

Before creating an issue, always confirm the summary, type, scope, and description with

the user — issues are visible to the team immediately.

When MCP tools aren't enough

If MCP tools lack a capability you need (e.g., bulk operations, complex queries, attachment

uploads, or reading fields not exposed by the MCP tools), fall back to the YouTrack REST API

directly. The YOUTRACK_TOKEN environment variable contains a permanent Bearer token:

curl -s -H "Authorization: Bearer $YOUTRACK_TOKEN" \
  "https://youtrack.jetbrains.com/api/issues?query=project:KRPC&fields=id,summary"

The REST API base URL is https://youtrack.jetbrains.com/api. See the

YouTrack REST API docs

for available endpoints.

Required and Recommended Fields

Read references/krpc-fields.md for the full field reference (scopes, types, priority, tags,

optional fields). The key points:

• Every issue must have at least one Scope — determine it from the annotation/API used,

not the serialization format.

• Default Priority to Normal.
• Always add the Vibe-report tag after creation (mandatory for AI-created issues).
• Scope must be a JSON array, even for a single value.

Writing the Description

Read references/description-templates.md for per-type templates (Bug, Feature/Task,

Meta Issue, Usability/Performance).

The critical rule: Do NOT include proposed solutions or implementation approaches.

The agent's job is to analyze and report the problem clearly, not to solve it. Only include

an approach if the user explicitly dictates one.

Searching Before Filing

YouTrack does not have semantic search — it only matches exact keywords. A single broad

query will miss duplicates. Run at least 3-5 targeted queries using different keyword

combinations and synonyms:

mcp__youtrack__search_issues(query="project: KRPC <exact keyword 1>")
mcp__youtrack__search_issues(query="project: KRPC <exact keyword 2>")
mcp__youtrack__search_issues(query="project: KRPC <synonym or related term>")
mcp__youtrack__search_issues(query="project: KRPC Scope: {<relevant scope>}")

For example, for a streaming flow completion bug, search for:

• project: KRPC callServerStreaming
• project: KRPC streaming flow completes
• project: KRPC flow hang
• project: KRPC Scope: {kRPC. Client}

Also use scope-filtered searches to browse related issues. If a potential duplicate exists,

mention it to the user and let them decide.

Creating the Issue

Use mcp__youtrack__create_issue with these parameters:

project: "KRPC"
summary: "<concise title — imperative or noun phrase>"
description: "<markdown description following templates from references/description-templates.md>"
customFields: {
  "Type": "<one of the types from references/krpc-fields.md>",
  "Priority": "<priority>",
  "Scope": ["<scope1>", "<scope2>"]   # MUST be a JSON array, not a comma-separated string, even if there's only one
}

Multiline text fields (description, summary): The parameter value must contain

actual newlines, not literal \n escape sequences. YouTrack stores the string as-is —

literal \n will render as visible \n characters instead of line breaks.

Then immediately add the Vibe-report tag (mandatory for AI-created issues) plus any other

relevant tags with mcp__youtrack__manage_issue_tags.

Summary Guidelines

• Keep summaries concise but specific (under ~80 characters)
• For GitHub-sourced issues, prefix with [GitHub]
• Use noun phrases or imperative form: "KLIB unique_name collision" or "Add context7.json"
• Include the affected component when it aids clarity

After Creation

After creating the issue, report back:

• The issue ID and URL (e.g., KRPC-540 https://youtrack.jetbrains.com/issue/KRPC-540)
• A brief summary of what was filed
• Which tags were added

If the user wants to link it to a parent issue, use the parentIssue parameter. If they want

to add comments or other modifications after creation, use mcp__youtrack__update_issue.

Quick Reference: Common Workflows

User reports a bug while coding:

• Ask what happened (or infer from context)
• Identify scope from the annotations/APIs used (not serialization format)
• Search for duplicates with multiple keyword queries
• Draft the issue and confirm with user
• Create it and add Vibe-report tag + any other relevant tags

User wants to track a task:

• Clarify what needs to be done
• Pick Type=Task and appropriate scope
• Create with brief description (no approach/solution)
• Add Vibe-report tag + any other relevant tags

User mentions a GitHub issue to track:

• Get the GitHub URL
• Create with [GitHub] prefix and link in description
• Type is usually Bug unless stated otherwise
• Do NOT add github-issue tag — it's auto-imported
• Add Vibe-report tag
