Claude Code Subagents · page 12

Systematic open source contributor that analyzes projects, finds suitable issues, implements fixes, and creates high-quality PRs with high acceptance probability.

Application security expert specializing in SAST, vulnerability assessment, OWASP Top 10, compliance auditing, and security architecture review.

Fullstack code reviewer with 15+ years experience analyzing code for security vulnerabilities, performance bottlenecks, architectural decisions, and best practices.

Senior technical lead who analyzes complex projects and coordinates multi-step development tasks. Delegates to specialized agents and ensures quality delivery.

Use proactively before opening a PR that adds or changes BehaviorTree.CPP nodes or BehaviorTree.ROS2 wrappers (RosActionNode/RosServiceNode/RosTopicPub/SubNode, TreeExecutionServer). Reviews a diff against BT.CPP v4 conventions — node base-class choice, non-blocking ticks, ports/blackboard typing, factory/plugin registration, XML v4, and the ROS 2 wrapper contract. Returns a punch list with file:line anchors, not a rewrite.

Use when a design decision touches Clean Architecture boundaries in a ROS 2 project — which layer a new behaviour belongs to, whether a port belongs in domain or application, whether a new node should be lifecycle-managed, whether to compose nodes or split packages. Returns an architectural recommendation with trade-offs, not implementation.

Use when a design decision touches the gz-sim ECS — where new state should live, which system phase should write it, how to avoid coupling, whether to add a component vs. a member variable, whether a new system should be split or merged with an existing one. Returns an architectural recommendation with trade-offs, not implementation.

Use proactively before opening any gz-sim PR. Reviews a diff against the project's C++17 style, ECS conventions, plugin registration patterns, CMake structure, test placement, Migration.md / Changelog.md expectations, and pre-commit configuration. Returns a punch list, not a rewrite.

Use proactively before opening a PR that adds or changes a ros2_control controller, broadcaster, or hardware component (incl. URDF <ros2_control> bringup). Reviews a diff against ros2_controllers / ros2_control_demos conventions — controller & hardware lifecycle, command/state interface configuration, real-time safety of update()/read()/write(), generate_parameter_library usage, pluginlib registration, chainable-controller correctness, URDF wiring, and tests. Returns a punch list with file:line anchors, not a rewrite.

Use proactively before opening any ROS 2 / Nav 2 PR. Reviews a diff against this template's Clean Architecture, ROS 2 communication, lifecycle, testing, and Nav 2 plugin conventions. Returns a punch list with file:line anchors, not a rewrite.

Use proactively before opening a PR that touches a VDA 5050 connector / fleet bridge. Reviews a diff against VDA 5050 v3.0.0 protocol compliance (topics, QoS, header rules, base/horizon, action state machine, schema validation) and the template's Clean Architecture for the MQTT↔Nav 2 bridge. Returns a punch list with file:line anchors, not a rewrite.

Cross-artifact consistency and coverage analysis specialist with Anthropic think protocol. Validates alignment between specifications, plans, tasks, and implementation. Use before implementation to catch conflicts early.

Production deployment specialist with Anthropic safety patterns managing CI/CD pipelines, infrastructure provisioning, and safe rollout strategies. Defaults to canary deployments with auto-rollback. Use for production deployments and release management.

Root cause analysis and debugging specialist with Anthropic think protocol and 3-retry limit. Focuses on systematic problem diagnosis, error tracing, and fix validation. Use for complex bugs and system failures.

Observability and monitoring specialist with Anthropic's three pillars pattern (Metrics, Logs, Traces). Sets up comprehensive monitoring, SLI/SLO tracking, and incident detection. Use for system observability and proactive alerting.

Performance optimization and auto-scaling specialist with Anthropic profiling patterns. Manages horizontal/vertical scaling, load balancing, caching strategies, and continuous performance tuning. Use for scaling challenges and performance work.

Master orchestrator for complex, multi-faceted software projects. Coordinates specialist agents (researchers, planners, implementers) to deliver cohesive solutions. Use for projects requiring 3+ capabilities or cross-domain work (frontend + backend + devops).

Precision execution specialist that implements code following Implementation Plans and ResearchPacks. Makes surgical, minimal edits with self-correction capability (3 retries). Always runs tests and validates against plan. Requires both ResearchPack and Implementation Plan as input.

High-speed documentation specialist. Fetches version-accurate docs from official sources to prevent coding from stale memory. Use before implementing any feature with external libraries or APIs. Delivers ResearchPack in < 2 minutes.

Strategic architect that transforms ResearchPacks into surgical, reversible implementation plans. Analyzes codebase structure, identifies minimal changes, and creates step-by-step blueprints with rollback procedures. Requires ResearchPack as input.

Idun coding-guideline review against the active rule set.

Use to watch the whole cc-fleet fleet live from inside this session — it surfaces a running fleet in the agent panel and streams the status board (provider teammates, one-shot subagent jobs, and workflow runs) until interrupted.

Use to watch a running cc-fleet workflow run live from inside this session — it surfaces the run in the agent panel and streams its status until the run finishes. Invoke with the run id (and, on a reattach, the last seq from the previous "still running (seq=N)" line).

WOZCODE free-plan fallback agent — active when the monthly free-plan cap is exhausted. Claude Code's built-in Read, Edit, Write, Grep, Glob, and NotebookEdit are available; WOZCODE MCP tools are disallowed until the cap resets or the user upgrades.

WozCode enhanced coding agent with smart search, batch editing, and SQL introspection. Use as the default main thread agent.

Fast read-only agent for file searches, symbol lookups, and codebase questions like "where is X defined?", "where is X called?", or "how does X flow through the system?". Prefer over shell-based exploration when answering would take 3+ Search/Sql calls. Cheaper model (haiku) so delegation pays for itself on any real scan.
