-name: tang
-description: |
-  Use this skill when the user asks about this repo on Tangled, Tangled issues,
-  Tangled pull requests, or Tangled operations. The current git remote is a
-  Tangled repo, so `tang` can usually infer the repository from the worktree.
----
-
-# tang — Tangled repo workflow
-
-This repo packages [`tang`](https://tangled.org/onev.cat/tang) in `devenv`.
-Use it for Tangled operations.
-
-## Repository selection
-
-Prefer the current git worktree. `tang` discovers the repo from `.git` remotes,
-so in this repo use commands without `--repo` / `-R` by default:
-
-```bash
-tang status
-tang repo view
-tang issue list
-tang pr list
-```
-
-Only add `-R <owner>/<repo>` when the user explicitly asks about a different
-Tangled repo.
-
-## Auth
-
-Reads often work without auth. Writes require login:
-
-```bash
-bash .agents/skills/tang/auth.sh
-```
-
-The bootstrap uses `ATPROTO_HANDLE` / `ATPROTO_APP_PASSWORD`, falling back to
-`BSKY_HANDLE` / `BSKY_APP_PASSWORD`. App passwords are created at
-<https://bsky.app/settings/app-passwords>. Never use the main account password.
-
-## Common commands for this repo
-
-```bash
-# Inspect
-tang status
-tang repo view
-tang issue list
-tang issue view <number-or-rkey>
-tang pr list
-tang pr view <number-or-rkey>
-tang pr diff <number-or-rkey>
-
-# Issues
-tang issue create "Title" --body "Body"
-tang issue comment <number-or-rkey> --body "Comment"
-tang issue close <number-or-rkey>
-tang issue reopen <number-or-rkey>
-
-# Pull requests
-tang pr create --base main --head <branch> --title "Title"
-tang pr comment <number-or-rkey> --body "Comment"
-tang pr checkout <number-or-rkey>
-tang pr merge <number-or-rkey> --subject "Merge pull request #N"
-```
-
-## Identifiers
-
-Numeric issue and PR IDs match Tangled web URLs. For raw protocol records, use
-`--atproto` with an AT URI, rkey, or unique rkey prefix.
-
-## Safety
-
-Ask before performing writes against a different repo than the current worktree,
-or when auth is unavailable.
