Forge usage was spread across AGENTS.md, docs/agents/issue-tracker.md, and whatever the agent remembered about `gh`. Move the how-to-run-`tea` half into a model-invoked skill so it loads on any issue/PR task, and leave AGENTS.md a single line of identity plus pointers. The skill carries only what `tea --help` cannot answer: `gh` is absent so the harness's `issue://`/`pr://` URIs error out, issues and PRs share one index space, rendered-box output needs `-o json`, `close` takes no `--comment`, labels never auto-create, bodies need a heredoc, and a read without `--comments` silently drops every comment (issue #123: 40 lines bare, 132 with the flag). Tracker conventions and triage label strings stay in docs/agents/, cited rather than copied.
