Do Issue Skill for Claude

When NOT To Use

• A single-file fix obvious enough to make directly
• Preparing the PR once the work is done (use sanctum:pr-prep)

Fix Issue(s)

Retrieves issue content from the detected git platform (GitHub, GitLab, or Bitbucket) and uses subagent-driven-development to systematically address requirements, executing tasks in parallel where dependencies allow.

Platform detection is automatic via the leyline:git-platform SessionStart hook. Check session context for git_platform: to determine which CLI to use.

Key Features

• Cross-Platform: Automatically detects GitHub/GitLab/Bitbucket and uses appropriate CLI
• Flexible Input: Single issue number, platform URL, or space-delimited list
• Parallel Execution: Independent tasks run concurrently via subagents
• One PR: All issues produce one consolidated PR (never per-issue PRs)
• Quality Gates: Code review between task groups
• Fresh Context: Each subagent starts with clean context for focused work

Workflow Overview

| Phase | Description | Module |

|-------|-------------|--------|

| 1. Discovery | Parse input, fetch issues, extract requirements | issue-discovery |

| 2. Planning | Analyze dependencies, create task breakdown | task-planning |

| 3. Execution | Dispatch parallel subagents for independent tasks | parallel-execution |

| 4. Quality | Code review gates between task batches | quality-gates |

| 5-6. Completion | Sequential tasks, final review, issue updates | completion |

Required TodoWrite Items

• do-issue:discovery-complete
• do-issue:tasks-planned
• do-issue:parallel-batch-complete
• do-issue:review-passed
• do-issue:sequential-complete
• do-issue:issues-updated

Forge CLI Commands

Use the platform detected in session context (git_platform:). See Skill(leyline:git-platform) for full mapping.

| Operation | GitHub (gh) | GitLab (glab) |

|-----------|---------------|-----------------|

| Fetch issue | gh issue view <N> --json title,body,labels,comments | glab issue view <N> |

| Comment | gh issue comment <N> --body "msg" | glab issue note <N> --message "msg" |

| Close | gh issue close <N> --comment "reason" | glab issue close <N> |

| Search | gh issue list --search "query" | glab issue list --search "query" |

Verification: Run the command with --help flag to verify availability.

Agent Teams (Default Execution Mode)

Agent teams is the default parallel execution backend for do-issue. Teammates coordinate via filesystem-based messaging, enabling real-time communication when shared files or dependencies are discovered mid-implementation.

Automatic downgrade: For single issues with --scope minor, agent teams is skipped (Task tool or inline execution is used instead). Use --no-agent-teams to force Task tool dispatch for any invocation.

Requires: Claude Code 2.1.32+, tmux, CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1. If prerequisites are missing, silently falls back to Task tool dispatch.

# Agent teams configuration
fix_issue:
  agent_teams:
    enabled: true           # on by default; --no-agent-teams to disable
    max_teammates: 4        # limit concurrent workers
    model: sonnet           # teammate model (lead uses current model)
    auto_downgrade: true    # skip agent teams for --scope minor

See modules/parallel-execution.md for detailed agent teams patterns.

Configuration

fix_issue:
  parallel_execution: true
  max_parallel_subagents: 3
  review_between_batches: true
  auto_close_issues: false
  commit_per_task: true

Verification: Run the command with --help flag to verify availability.

Exit Criteria

• [ ] All 6 required TodoWrite items (do-issue:discovery-complete

through do-issue:issues-updated) are created before execution

starts and each marked complete when its phase finishes

• [ ] Issue requirements fetched using the correct forge CLI (gh for

GitHub, glab for GitLab) as detected in session context

• [ ] Exactly one consolidated PR is opened covering all issues; no

per-issue PRs are created

• [ ] Code review gate runs between parallel task batches and must

pass before the next batch is dispatched

• [ ] All specified issues are commented on or closed with a reference

to the PR after it is ready for review
