# Available Capabilities

This project uses specialized capabilities. Always check for existing capabilities before implementing similar functionality.

## Issue Tracking: issue-core

**Location:** `capabilities/issue-core/`
**Documentation:** `.claude/capabilities/issue-core.md`
**Priority:** CRITICAL (always use for issue operations)

**MUST USE FOR:**
- Creating, reading, updating, searching issues
- Multi-agent coordination via issue tracking
- Querying issue state or assigning issues

**NEVER USE:**
- Direct API calls to Gitea/GitHub/GitLab (`requests.post("/api/v1/repos/...")`)
- Platform CLIs (`gh issue`, `glab issue`)
- Platform libraries (`from github import Github`)

**Quick Start:**
```python
from issue_core.backends.gitea import GiteaBackend
backend = GiteaBackend()
backend.connect(config)
issues = backend.list_issues()
```

**Full Documentation:** See `.claude/capabilities/issue-core.md`

You are working with issue tracking. Use the **issue-core capability**:

## Available API

**Python (Recommended):**
```python
from issue_core.backends.gitea import GiteaBackend
from issue_core.core.models import Issue, Label, IssueState
from issue_core.core.interfaces import IssueFilter

backend = GiteaBackend()
backend.connect(config)

# Query issues
issues = backend.list_issues(IssueFilter(state='open', labels=['bug']))

# Create issue
issue = Issue(...)
backend.create_issue(issue)

# Update
issue.state = IssueState.CLOSED
backend.update_issue(issue)
```

**CLI:**
```bash
issue list --state=open --label=bug --format=json
issue create "Title" --label=bug --description="Details"
issue edit 42 --state=in_progress
issue close 42 --comment="Fixed"
```

## Critical Reminders

**DO NOT:**
- ❌ Make direct API calls to Gitea/GitHub/GitLab
- ❌ Use `gh` or `glab` CLI tools
- ❌ Import PyGithub, python-gitlab, or similar libraries
- ❌ Parse HTML or scrape web UIs

**WHY:** Bypassing the capability causes credential sprawl, token waste, and race conditions.
