What it does

Reviewing Changes is an agent skill from bitwarden/ios, published by the product's own GitHub organization. Performs comprehensive code reviews for Bitwarden iOS projects, verifying architecture compliance, style guidelines, compilation safety, test coverage, and security requirements. Use when reviewing pull requests, checking commits, analyzing code changes, verifying Bitwarden coding standards, evaluating unidirectional data flow pattern, checking services container dependency injection usage, reviewing security implementations, or assessing test coverage. Automatically invoked by CI pipeline or manually for…

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 15 other files (for example `checklists/bug-fix.md`, `checklists/dependency-update.md` and `checklists/feature-addition.md`).

It sits in Development, covering Code review, Test coverage and Pull requests. It works with iOS and GitHub. The repository describes itself as: Bitwarden mobile apps (Password Manager and Authenticator) for iOS. The licence is GPL-3.0.

What it can do on your machine

Read from SKILL.md and the folder at commit 6399b1d. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Reviewing Changes loads about 1.1k tokens when it runs. Until then it costs about 139 tokens; SKILL.md has 388 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~139
When it runs · the whole SKILL.md, loaded when a task matches: ~1.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Reviewing Changes — Bitwarden iOS

Instructions

Work systematically through each step before providing feedback. Each checklist loads only the relevant review strategy for the change type detected.

Step 1: Retrieve Additional Details

Fetch any additional context using available tools (JIRA MCP, GitHub API). If the PR title and description don't provide enough context, request:

A link to the JIRA ticket
A GitHub issue reference
More detail in the PR description

iOS-specific metadata checks:

Screenshots required for any *View.swift changes that affect visible UI — flag as ❓ if absent
If new *Processor.swift or *Service.swift is added with no test file, flag as ❓

Step 2: Detect Change Type

iOS-specific patterns:

Feature Addition: New *Coordinator.swift, *Processor.swift, *View.swift (full file-set); new screen or flow
Bug Fix: Targeted changes to existing *Processor.swift, *Service.swift, or *Repository.swift files
UI Change: Changes only to *View.swift files; no business logic changes
Refactoring: Renamed/restructured files without new user-visible behavior
Dependency Update: Changes to Mintfile, project-*.yml version references, Package.swift
Infrastructure: Changes to Scripts/, Configs/, .github/, fastlane/

Step 3: Load Appropriate Checklist

Based on detected type, read the relevant checklist file:

Dependency Update → checklists/dependency-update.md (expedited review)
Bug Fix → checklists/bug-fix.md (focused: fix correctness + regression test)
Feature Addition → checklists/feature-addition.md (comprehensive: all areas)
UI Change → checklists/ui-change.md (UDF compliance + accessibility + snapshots)
Refactoring → Full architecture check: verify behavior-preserving via reference/ios-architecture-patterns.md
Infrastructure → Security review + deployment impact assessment

The checklist provides: multi-pass review strategy, type-specific focus areas, what to check and what to skip.

Show full SKILL.md (155 more words)Show less

Step 4: Execute Review Following Checklist

Follow the checklist's review strategy, thinking through each pass systematically before writing feedback.

Step 5: Consult Reference Materials As Needed

Load reference files only when needed for specific questions:

Re-reviews (incremental) → invoke reviewing-incremental-changes agent skill; scope to changed lines only, do not flag new issues in unchanged code
Issue prioritization → reference/priority-framework.md (Critical vs Important vs Suggested)
Phrasing feedback → reference/feedback-psychology.md (questions vs commands, I-statements)
Architecture questions → reference/ios-architecture-patterns.md + Docs/Architecture.md
Security questions → reference/ios-security-patterns.md
Testing questions → reference/ios-testing-patterns.md
Style questions → reference/ios-style-patterns.md
Output format → examples/annotated-example.md

Core Principles

Priority order: Security → Correctness → Breaking Changes → Performance → Maintainability
Appropriate depth: Match review rigor to change complexity and risk. A dependency update doesn't need architecture review.
Specific references: Always use file:line_number format for precise locations
Actionable feedback: Say what to change and why — not just what's wrong
Efficient reviews: Use the change-type checklist, skip what's not relevant
iOS patterns: Validate UDF, Has* DI, store.binding, Sourcery mock conventions, StateProcessor subclass
