bb_get

Read any Bitbucket data. Returns TOON format by default (30-60% fewer tokens than JSON). **IMPORTANT - Cost Optimization:** - ALWAYS use `jq` param to filter response fields. Unfiltered responses are very expensive! - Use `pagelen` query param to restrict result count (e.g., `pagelen: "5"`) - If unsure about available fields, first fetch ONE item with `pagelen: "1"` and NO jq filter to explore the schema, then use jq in subsequent calls **Schema Discovery Pattern:** 1. First call: `path: "/workspaces", queryParams: {"pagelen": "1"}` (no jq) - explore available fields 2. Then use: `jq: "values[*].{slug: slug, name: name, uuid: uuid}"` - extract only what you need **Output format:** TOON (default, token-efficient) or JSON (`outputFormat: "json"`) **Common paths:** - `/workspaces` - list workspaces - `/repositories/{workspace}` - list repos in workspace - `/repositories/{workspace}/{repo}` - get repo details - `/repositories/{workspace}/{repo}/pullrequests` - list PRs - `/repositories/{workspace}/{repo}/pullrequests/{id}` - get PR details - `/repositories/{workspace}/{repo}/pullrequests/{id}/comments` - list PR comments - `/repositories/{workspace}/{repo}/pullrequests/{id}/diff` - get PR diff - `/repositories/{workspace}/{repo}/refs/branches` - list branches - `/repositories/{workspace}/{repo}/commits` - list commits - `/repositories/{workspace}/{repo}/src/{commit}/{filepath}` - get file content - `/repositories/{workspace}/{repo}/diff/{source}..{destination}` - compare branches/commits **Query params:** `pagelen` (page size), `page` (page number), `q` (filter), `sort` (order), `fields` (sparse response) **Example filters (q param):** `state="OPEN"`, `source.branch.name="feature"`, `title~"bug"` **JQ examples:** `values[*].slug`, `values[0]`, `values[*].{name: name, uuid: uuid}` The `/2.0` prefix is added automatically.
