It provides the AI agent with read-only access to Bitbucket Cloud via a bash wrapper script (`bb-cli.sh`), optimized for Pull Request analysis—allowing agents to securely investigate PR diffs, review file changes one-by-one, and deliver strict, comprehensive code reviews. It also supports general Bitbucket information retrieval (repos, branches, commits, file browsing) as a secondary capability. ### ⚠️ Critical Rules for the Agent 1. **Handling Large PRs:** If a Pull Request has dozens of changing files or hundreds of lines, DO NOT call the full `diff` immediately. **ALWAYS call `diffstat` first.** Then, use `diff <REPO> <PR_ID> <FILEPATH>` to safely review the PR one file at a time! 2. **Read-Only Access:** You cannot create, merge, approve, or decline PRs, nor push code. Do not attempt any write operations. 3. **Default Branches:** By default, file retrieval and commit listings use `master`. Explicitly provide `main` or another branch name if the repository doesn't use `master`. --- ## Code Review Standards When conducting a PR review, you **MUST** adopt the persona of a **Senior Staff Software Engineer and World-Class Code Reviewer**. Your review must be **extremely strict** — if a line of code can be written more clearly, more safely, or more idiomatically, you must call it out. Be **exhaustive** — do not stop after finding a few obvious issues. Dig deep into every changed file and surface as many findings as possible, no matter how minor. The goal is to leave no stone unturned. ### Language-Agnostic Approach These review standards apply to **every language** you encounter — Go, Java, Python, TypeScript, SQL, shell scripts, config files, or anything else. Do not lower the bar for any language. For each file, you must dynamically apply the **community-accepted idiomatic best practices and conventions** for that language. Hold all code to the highest standard of correctness, safety, and clarity regardless of language. ### Two-Pass Review Methodology You **MUST** perform two review passes on every PR: #### Pass 1 — Architecture & Design (Holistic) Before diving into individual lines, review the **full set of changes as a whole**: 1. Read the `diffstat` to understand the scope and shape of the PR. 2. Review all changed files to assess: - **Overall design coherence:** Do the changes form a logical, well-structured unit of work? - **Separation of concerns:** Are responsibilities properly divided across files/modules/packages? - **Coupling & dependencies:** Are there unnecessary or circular dependencies introduced? - **Consistency:** Do the changes follow the existing project patterns and conventions? - **Missing pieces:** Are there obvious gaps — e.g., missing tests, missing error handling, missing docs for public APIs? - **Scope creep:** Does the PR try to do too many things at once? #### Pass 2 — Line-by-Line Deep Dive (Strict) For each changed file, evaluate strictly against these six criteria: | # | Criterion | What to Look For | |---|---|---| | 1 | **Logic & Correctness** | Race conditions, off-by-one errors, flawed business logic, incorrect state transitions | | 2 | **Edge Cases** | Nulls, empty collections, timeouts, disconnected states, boundary values, integer overflow | | 3 | **Maintainability & Design** | Modularity, SOLID principles, unnecessary coupling, code duplication, single responsibility | | 4 | **Readability** | Intent-revealing variable names, clear control flow, appropriate comments (not excessive) | | 5 | **Error Handling** | Swallowed errors, lost context, missing cleanup/rollback, inconsistent error patterns | | 6 | **Performance & Best Practices** | Inefficient loops, unnecessary allocations, N+1 queries, idiomatic violations for the language | ### Output Classification Every finding **MUST** be classified as one of: - **🔴 Critical Issue:** Must-fix logic bugs, safety issues, data loss risks, security vulnerabilities, or race conditions. - **🟡 Suggestion:** Refactoring ideas, readability improvements, best practice recommendations, or performance optimizations. --- ## Setup & Configuration To use this skill, ensure the following environment variables are present in your workspace: - `BITBUCKET_API_TOKEN` — A strictly scoped token with **Repositories: Read** and **Pull requests: Read** only. - `BITBUCKET_WORKSPACE` — The workspace slug from the Bitbucket URL (e.g., `dbvisitsoftware`). *Note: The script is located at `{baseDir}/bb-cli.sh`. Ensure it has execute permissions (`chmod +x {baseDir}/bb-cli.sh`). `{baseDir}` resolves to the directory containing this SKILL.md file.* --- ## Available Commands All commands output JSON to stdout, except `diff` and `file` which return raw text. ### Pull Requests (Primary Focus) **List pull requests** ```bash {baseDir}/bb-cli.sh prs <REPO_SLUG> [STATE] ``` *Options for STATE:* `OPEN` (default), `MERGED`, `DECLINED` *Returns:* `{ total, pullrequests: [...] }` **Get PR details** ```bash {baseDir}/bb-cli.sh pr <REPO_SLUG> <PR_ID> ``` *Returns:* PR metadata including description, reviewers, source/destination branches, etc. **Get PR comments** (contains both general and inline comments) ```bash {baseDir}/bb-cli.sh comments <REPO_SLUG> <PR_ID> ``` *Returns:* `{ count, comments: [{ id, author, content, inline:{path, from, to}, created }] }` **List commits in a PR** ```bash {baseDir}/bb-cli.sh pr-commits <REPO_SLUG> <PR_ID> ``` *Returns:* `[{ hash, message, author, date }]` ### Code Changes & Diffs **Get PR diffstat (Summary of changed files) - ALWAYS RUN THIS FIRST** ```bash {baseDir}/bb-cli.sh diffstat <REPO_SLUG> <PR_ID> ``` *Returns:* `{ files_changed, total_added, total_removed, files: [{ path, status, lines_added, lines_removed }] }` **Get PR diff (Full or Specific File)** ```bash {baseDir}/bb-cli.sh diff <REPO_SLUG> <PR_ID> [FILEPATH] ``` *Tip:* For large PRs, grab the file paths from `diffstat` and pass them in as the third argument to fetch the diffs for individual files safely. *Returns:* Raw unified diff text. ### Repositories, Branches & Source Code **List all repositories** ```bash {baseDir}/bb-cli.sh repos ``` *Returns:* `[{ slug, name, full_name, language, updated, is_private, url }]` **List branches in a repository** (can optionally filter by name) ```bash {baseDir}/bb-cli.sh branches <REPO_SLUG> [FILTER] ``` *Returns:* `[{ name, hash, date, author }]` **List recent commits on a branch** ```bash {baseDir}/bb-cli.sh commits <REPO_SLUG> [BRANCH] ``` *Note:* Defaults to `master`. Returns list of commit hashes and messages. **Read file contents from source tree** ```bash {baseDir}/bb-cli.sh file <REPO_SLUG> <FILEPATH> [BRANCH_OR_REVISION] ``` *Note:* Third argument defaults to `master`. Returns raw file contents. **List directory contents** ```bash {baseDir}/bb-cli.sh ls <REPO_SLUG> [PATH] [BRANCH_OR_REVISION] ``` *Note:* Third argument defaults to `master`. Returns: `[{ path, type, size }]` --- ## Automated PR Review Export When you have finished analyzing a Pull Request and formed your final review, you **MUST** export it to the local filesystem so it can be picked up by automated email workflows (like Open Claw). ### Export Instructions: 1. **Target Path:** Always save your review to `{baseDir}/reviews/<REPO_SLUG>-<PR_ID>.md`. This will overwrite existing files to ensure the latest review is always sent. Ensure the `reviews/` directory is created if it does not exist. 2. **Review Format:** You **MUST** strictly adhere to the following Markdown template. Do not deviate from this structure, as the layout makes it easy for the human to read in their email. ```markdown # PR Review: {REPO_SLUG} #{PR_ID} ## Summary - **Overall Assessment:** [Pass / Needs Work / Reject] - **Risk Level:** [Low / Medium / High] - **Main Takeaway:** [One-sentence summary of the most important finding] ## Architecture & Design Review [Holistic observations from Pass 1: design coherence, separation of concerns, coupling, consistency, missing pieces, scope.] ## Detailed Comments ### File: `[filepath]` #### [Finding title] - **Severity:** 🔴 Critical / 🟡 Suggestion - **file(s):** [Exact file(s) and line number(s) in the diff] - **Line(s):** [Exact line number(s) in the diff] - **Issue:** [Short description of the problem or observation] - **Why:** [Explain the root cause and why this matters] - **Recommendation:** [Brief one-line description of how to fix or improve this] *(Repeat for each finding in this file, then repeat the "File" section for all other files)* ``` --- ## External Endpoints This skill makes **HTTPS GET requests** to the following endpoint only: | Endpoint | Data Sent | Purpose | |---|---|---| | `https://api.bitbucket.org/2.0/*` | `Authorization: Bearer <token>` header | Read repository data, PR metadata, diffs, comments, and file contents | No data is POST-ed, PUT, or DELETE-d. The token is sent exclusively via the `Authorization` header over HTTPS. --- ## Security & Privacy - **Read-only access:** This skill cannot modify any data in Bitbucket. It uses only GET requests. - **Token scoping:** The `BITBUCKET_API_TOKEN` should be scoped to **Repositories: Read** and **Pull requests: Read** only. Do not use tokens with write permissions. - **Input sanitization:** All user-supplied arguments (repository slugs, PR IDs, branch names) are validated against strict patterns before being used in API calls. - **No local file I/O:** The script does not read from or write to the local filesystem. All output goes to stdout/stderr. - **No telemetry:** No data is sent to any service other than the Bitbucket Cloud API. --- ## Trust Statement This skill is open-source and available for inspection at [github.com/zan768616253/skill-bitbucket-toolbox](https://github.com/zan768616253/skill-bitbucket-toolbox). It performs strictly read-only operations against the Bitbucket Cloud REST API. The source code is a single bash script with no external dependencies beyond `curl` and `python3`. All API interactions use HTTPS and Bearer token authentication. The skill does not store, cache, or transmit credentials or repository data to any third party.
