ln-11-plan-reviewer

Reviews implementation plans against repository evidence and current authoritative guidance. Use before execution to expose gaps and risks; not for completed delivery review.

ln-23-test-suite-auditor

Audits whether an existing test suite proves important behavior as a sustainable portfolio. Use when test confidence or lifecycle control is uncertain; not to implement tests or review one delivery.

ln-61-skill-reviewer

Reviews standalone skills and their configured distribution surfaces before publication. Use for skill release readiness; not for product code or implementation-plan review.

ln-31-performance-optimizer

Optimizes a measured latency, throughput, memory, CPU, or I/O problem through profiling and keep-or-discard experiments. Use for a known bottleneck; not unbiased A/B comparison.

ln-33-code-modernizer

Modernizes a bounded capability by removing obsolete custom mechanisms or reducing bundle and maintenance cost. Use for proven modernization value; not routine upgrades or tuning.

ln-34-benchmark-comparator

Compares tools or implementations through reproducible A/B workloads, correctness oracles, and controlled measurements. Use to choose alternatives; not to optimize a known bottleneck.

ln-35-surgical-change-implementer

Implements a bounded product-code change through the smallest complete root-cause solution. Use for scoped delivery; not for planning, review, audit, upgrades, modernization, or tuning.

ln-12-delivery-reviewer

Reviews a completed scoped change and its affected runtime and contract paths. Use to find change-caused defects and verify readiness; not for codebase audit, implementation, or repair.

ln-41-test-strategy-planner

Designs risk-based test portfolio decisions and prioritized scenarios without changing code. Use when requirements need a test strategy; not for auditing or implementing tests.

ln-42-acceptance-test-builder

Creates, updates, consolidates, retires, and runs scoped acceptance tests using project-native tooling. Use when executable acceptance evidence must change; not for audits or product fixes.

ln-21-documentation-auditor

Audits documentation and code comments for structure, coverage, factual accuracy, and maintainability. Use for documentation trust reviews; not code, test, or architecture audits.

ln-22-codebase-auditor

Audits cross-cutting code health across security, delivery, maintainability, dependencies, diagnosability, concurrency, and lifecycle. Use when no specialist audit is primary.

ln-24-architecture-auditor

Audits implemented architecture fitness, boundaries, contracts, dependencies, and configuration ownership. Use for system structure; not for current-state documentation, diagrams, or plan review.

ln-25-persistence-auditor

Audits queries, transactions, data-path performance, and persistence resource lifecycle. Use when data correctness or scalability is at risk; not for general performance tuning.

ln-62-repository-publisher

Validates, commits, pushes, and remotely verifies approved repository changes. Use when publication is requested; not for releases, package publishing, or announcements.

ln-63-release-publisher

Prepares and publishes a tagged GitHub release from repository evidence. Use for an explicit release request; not for ordinary commits, packages, or community news.

ln-73-system-design-proposal-builder

Creates a decision-complete target system design from requirements and constraints. Use before implementation planning; not for requirements baselines, reviews, audits, or code changes.

ln-75-architecture-diagram-builder

Creates evidence-backed current or target architecture diagrams when the diagram is the primary deliverable. Not for UI design, architecture audit, or invented structure.

ln-51-opportunity-evaluator

Evaluates new product directions using current demand, acquisition, competition, economics, and validation evidence. Use before commitment; not for backlog or implementation planning.

ln-71-system-design-baseline-builder

Creates a project baseline of architecture drivers and constraints. Use before design or planning; not for target design, plan review, implementation, or architecture audit.

ln-72-current-architecture-documenter

Documents implemented current-state architecture from repository evidence. Use for onboarding or migration baselines; not for target design, audit verdicts, or code changes.

ln-74-architecture-decision-recorder

Records one architecture decision with context, alternatives, tradeoffs, and consequences. Use for a significant choice; not for broad design, audit, or implementation.

ln-76-architecture-migration-planner

Plans a reversible architecture migration with compatibility, data movement, rollout, and rollback. Use for current-to-target transitions; not execution, generic planning, or delivery review.

ln-64-community-announcer

Drafts and publishes fact-checked GitHub Discussions announcements. Use for releases, updates, or project news; not for release creation or issue responses.

ln-32-dependency-upgrader

Upgrades dependencies across package managers with breaking-change research and rollback-safe verification. Use for dependency maintenance; not general code modernization.
