Acceptance Test Builder creates, updates, merges, retires, and runs scoped acceptance tests using project-native tooling. Use it when executable acceptance evidence must change, not for audits or product fixes.

Architecture Auditor reviews the architecture a system actually executes, checking boundaries, dependencies, contracts, and ownership. Use it when auditing implemented structure or drift, not when documenting plans or diagrams.

Architecture Decision Recorder records one architecture decision with context, alternatives, tradeoffs, and consequences. Use it for a significant choice, not for broad design, audits, or implementation work.

Architecture Diagram Builder creates small, evidence-backed architecture diagrams for current or target systems when the diagram is the main deliverable. It is used to document scope, relationships, and runtime structure without inventing details or doing UI design.

Architecture Migration Planner creates a reversible plan for moving from a current architecture to a target one. Use it for compatibility, data movement, rollout, cutover, rollback, and removal planning.

Benchmark Comparator compares alternatives with reproducible workloads, correctness oracles, and controlled measurements. Use it when choosing between tools or implementations, not when tuning one known bottleneck.

Code Modernizer modernizes a bounded capability when replacing obsolete mechanisms reduces maintenance, risk, duplication, or artifact cost. Use it for proven modernization work, not routine upgrades or cosmetic refactors.

Codebase Auditor performs broad, read-only audits of code health across security, delivery, maintainability, dependencies, diagnosability, concurrency, and lifecycle. Use it when no specialist review is the primary fit.

Community Announcer drafts fact-checked GitHub Discussions announcements for releases, updates, or project news. It gathers source evidence, prepares a reviewable draft, and publishes only after approval.

Current Architecture Documenter produces an evidence-based snapshot of the architecture implemented in a repository. Use it for onboarding or migration baselines when you need what exists now, not target design or code changes.

Delivery Reviewer reviews a completed scoped change and its affected runtime and contract paths. Use it to find change-caused defects and verify release readiness without widening scope or repairing code.

Dependency Upgrader updates packages in small batches with breaking-change research and verification. Use it for dependency maintenance across package managers when you need compatibility-checked upgrades and rollback-safe changes.

Documentation Auditor audits docs and code comments for structure, coverage, factual accuracy, and maintainability. Use it for documentation trust reviews, not for code, test, or architecture audits.

Opportunity Evaluator evaluates new product directions using demand, acquisition, competition, economics, and validation evidence. Use it before committing to a product idea, not for backlog or implementation planning.

Performance Optimizer improves a measured latency, throughput, memory, CPU, or I/O problem by profiling and testing keep-or-discard changes. Use it for a known bottleneck, not for unbiased A/B comparisons.

Persistence Auditor audits queries, transactions, caches, and persistence resource lifecycles in data-heavy code paths. Use it when data correctness or scalability is at risk, not for general performance tuning.

Plan Reviewer checks an implementation plan against repository evidence and current guidance before execution. It is used for a read-only second pass to expose gaps, risks, and unsupported assumptions.

Release Publisher prepares a tagged GitHub release from repository evidence and waits for approval before publishing. Use it when an explicit release is requested and you need version, notes, and validation checked first.

Repository Publisher validates approved repository changes, commits and pushes them, then verifies the result from the remote source. Use it when publication is requested, not for releases, package publishing, or announcements.

Skill Reviewer reviews standalone skills and their distribution surfaces before publication. Use it to check release readiness, contracts, and checklist compliance without changing the repository or external state.

Surgical Change Implementer delivers one approved product-code change through the smallest complete root-cause solution. Use it for scoped implementation work that needs focused editing and verification, not planning, review, or broad refactors.

System Design Baseline Builder creates or updates a durable source of truth for architecture drivers, constraints, and critical scenarios before design or planning. It is used to establish the baseline, not to review plans, implement solutions, or audit code.

System Design Proposal Builder turns requirements and constraints into a decision-complete target system design with boundaries, contracts, data flow, failure behavior, and tradeoffs. Use it before implementation planning, not for reviews, audits, or code changes.

Test Strategy Planner designs a read-only, risk-based test portfolio for a requested scope. Use it when you need prioritized scenarios and evidence decisions without changing code or implementing tests.

Test Suite Auditor reviews an existing test portfolio to judge what important behavior it proves, what coverage is missing, and what tests should be kept, merged, updated, or retired. Use it when test confidence or lifecycle control is uncertain.
