The library

sre · Organizations that need reliability engineering across services with error budgets and blameless incident response culture.

tpo · Multi-service systems where a single change spans repos and requires coordinated rollout with rollback safety.

dba · Database-first design that optimizes schema, relationships, and queries before application code is written.

web · Frontend teams that enforce strict TypeScript and reuse Shadcn/Radix components with React Hook Form validation.

L · Thai/multi-language Laravel teams that follow strict MVC patterns with Eloquent, Vanilla JS, and audit trails.

ui · Mobile UI teams building KMP apps with consistent Material3 design across Android/iOS.

adr · Teams that need to track architectural decisions over time for onboarding, audits, and reversing decisions later.

ci · Teams automating build, test, and deployment with matrix testing and multi-environment promotion gates.

ux · Digital products that prioritize user research and design validation before engineering investment.

QA Engineer · Quality gates that prevent regressions through comprehensive test coverage and automated validation.

db · Data-intensive applications that need optimal schema design and query tuning from first principles.

QA · Quality assurance that validates features meet acceptance criteria before production release.

dba · When data layer must be explicit and performant before backend implements repositories.

cto · Making infrastructure or agent-backbone choices with cross-cutting impact across teams.

rag · Building semantic search over regulatory documents (Verordnungen) when 700-word chunks matter.

dba · Building semantic search over regulatory documents (Verordnungen) when 700-word chunks matter.

sde · Staff-level coding when production discipline and maintainability matter over speed.

gitnexus-pr-facts-historian · Understanding PR scope before review when changed files, commits, and regressions matter.

penetration-tester · Demonstrating real security risk when authorized exploitation and impact assessment needed.

edgartools-architect · Planning major EdgarTools changes when beginner-friendly simplicity must survive refactor.

onboarding · Integrating edge models when monkeypatching and compilation workarounds need expert guidance.

ctf-solver · Solving web/pwn/crypto CTFs when systematic methodology beats guessing.

version-bumper · Automating releases when version coordination across repos needed.

pr-fix-implementer · Executing code fixes when the design is locked but implementation needs care.

new-entity · Creating ORM entities when schema design needs code generation.

code-simplifier · Cleaning code when reuse wins matter more than bug hunting.

docs-agent · Keeping docs fresh when code changes need user-facing explanation.

ark-researcher · Analyzing agent-at-scale patterns when McKinsey research needs synthesis.

documentation-accuracy-reviewer · Ensuring user docs match implementation when multi-layered documentation must stay in sync

react-normalizer · Applying company standards consistently when 2-iteration cap and business-logic preservation matter

perf-dev · Quantization/numerical compute when measured speedup with verified correctness beats speculation

compiler-architect · Compiler architecture when API-first IR design and provider-agnostic core logic matter

Technical Artist · Maintaining visual quality within hard performance budgets when per-platform constraints and LOD discipline matter

data-flow-tracer · Security audit when complete data-flow visualization and validation-gap discovery outweigh endpoint lists

explorer · Non-mutating intelligence gathering when read-only analysis and pattern detection matter

logging-subagent · High-concurrency Rust when structured field logging and span-based context tracing beat free-text logs

flutter-expert · Mentoring a team on Flutter patterns when Riverpod state is complex.

README · Parallel auditing of unfamiliar legacy code when multiple specialists are needed.

rails-refactoring-expert · Cleaning up working Rails code while keeping tests green.
