Jira Skill

View Jira issues, generate branch names from tickets, transition issue status — all via Atlassian MCP.

Trigger

• Keywords: jira, ticket, issue key ([A-Z][A-Z0-9]+-\d+), branch from ticket, transition status, start work, pr opened, pr merged
• User says /jira

When NOT to Use

• GitHub Issues → use /issue-analyze
• Searching Jira issues → v1.1 (deferred)
• Generic project management

Input Parsing

Extract issueKey and optional host from user input:

Input Format	Example	Extraction
Bare key	OK-51513	key=OK-51513
Full URL	https://foo.atlassian.net/browse/OK-51513	key=OK-51513, host=foo.atlassian.net
Software URL	https://foo.atlassian.net/jira/software/.../OK-51513	key=OK-51513, host=foo.atlassian.net
Branch context	(auto from git branch --show-current)	key via {TICKET_PATTERN} regex

Regex:

• Issue key: ([A-Z][A-Z0-9]+-\d+)
• Host: https?://([^/]+\.atlassian\.net)

CloudId Resolution

1. Call getAccessibleAtlassianResources()
2. 0 results → error: "Atlassian MCP not configured or unauthorized"
3. 1 result  → use its cloudId automatically
4. N results →
     Host provided and matches?    → use matching cloudId
     Host provided but no match?   → warn: "Host '<host>' not found. Available: ..." → AskUserQuestion to select or abort
     No host?                      → AskUserQuestion to choose instance

Do NOT persist cloudId. Resolve at runtime each time; Claude context naturally caches within a session.

Subcommand: view

Step	Action
1	Parse input → issueKey (+ host if URL)
2	Resolve cloudId
3	getJiraIssue(cloudId, issueKey)
4	Format output

Output format:

## KEY: Summary

| Field | Value |
|-------|-------|
| Status | ... |
| Assignee | ... |
| Priority | ... |
| Type | ... |
| Created | ... |

### Description
(first 500 chars, truncated if longer)

Subcommand: branch

Step	Action
1	Parse input → issueKey
2	Resolve cloudId
3	getJiraIssue → get summary + issuetype
4	Map issue type → branch prefix (see references/branch-policy.md)
5	Apply --type override if provided
6	Generate slug from summary
7	Assemble branch name: ${prefix}/${issueKey}-${slug}
8	Check collision (local + remote)
9	Plan mode: output branch name + command. Execute mode: run git checkout -b

See references/branch-policy.md for full mapping table, slug algorithm, and collision detection.

Plan output (default):

Branch: feat/OK-51513-add-user-profile-page
From: OK-51513 "Add user profile page" (Story)

To create: git checkout -b feat/OK-51513-add-user-profile-page

Execute mode (--execute): run git checkout -b <branch> directly.

Subcommand: transition

Step	Action
1	Parse input → issueKey + --event value
2	Resolve cloudId
3	getJiraIssue → current status
4	getTransitionsForJiraIssue → available transitions
5	Match event → target transition (see references/transition-mapping.md)
6	Plan mode: show plan. Execute mode: AskUserQuestion → transitionJiraIssue

See references/transition-mapping.md for event vocabulary, regex patterns, and resolution algorithm.

Plan output (default):

## Transition Plan

- Issue: OK-51513 "Add user profile page"
- Current: To Do
- Event: start_work
- Target: In Progress (transition id: 21)

Execute? /jira transition OK-51513 --event start_work --execute

Subcommand: create

Step	Action
1	Extract project key from input (bare key like OK, or from issue key prefix)
2	Resolve cloudId
3	getJiraProjectIssueTypesMetadata(cloudId, projectKey) → list available types
4	Validate issue type against available types (case-insensitive match)
5	Format description as markdown (see references/create-policy.md)
6	Plan mode: display creation plan. Execute mode: AskUserQuestion → createJiraIssue

Input sources (both supported):

• --summary and --description flags: explicit values
• Context inference: extract summary and description from user's prompt (structured content like Background, Items, etc.)

MCP call (createJiraIssue):

Parameter	Source
cloudId	Resolved via step 2
projectKey	From input
issueTypeName	Validated against available types
summary	From --summary or context
description	Formatted markdown from --description or context
contentFormat	Always "markdown"

Plan output (default):

## Create Issue Plan

- Project: OK
- Type: Task
- Summary: P1 Hardening — Quote state machine + Recovery Worker
- Description: (preview first 200 chars...)

Execute? /jira create OK --summary "..." --type Task --execute

Execute output:

✅ Created: OK-51514
https://yourorg.atlassian.net/browse/OK-51514

See references/create-policy.md for description format guidelines, project key extraction, and issue type validation.
