Interview-first drafter for URU (Universidad Rafael Urdaneta) thesis (TEG) chapters — writes one section at a time toward the evaluation rubric the jury grades against, Spanish output, URU chapter order (I. Problema → V. Propuesta), never fabricates data. Complements uru-thesis-reviewer. Use when drafting or iterating…
Skill Claude CodeCodex
Design URU-style thesis defense presentation specs — fixed institutional slide structure (portada, problema, objetivos, antecedentes, variables, metodología, resultados, conclusiones), Spanish-only content, logo placement rules (large centered cover, small top-left from slide 2). Outputs one .md slide-by-slide spec.…
Skill Claude CodeCodex
Continuous-feedback reviewer for URU (Universidad Rafael Urdaneta) theses. Emits ordered .md diff files (- old / + new) the author applies manually — never edits the .docx. Covers substance, structure, prose, citations vs NORMASURU2020. Tracks issues across sessions via stable IDs and carry-forward. Use when the user…
Skill Claude CodeCodex
Generate formal daily work reports from unstructured input. Asks output language once, processes one date per invocation, never infers tasks or hours, requires explicit close confirmation before generating, keeps reports/projects.md + reports/YYYY-MM-DD/{raw,commit,report}.md. Use on "reporte de trabajo", "daily…
Skill Claude CodeCodex
Vanilla gRPC standards — .proto services, status.Error with standard codes, domain→code mapping, interceptor chain (auth/log/recovery/validation/metrics), client deadlines, context propagation, reflection off in prod, bufconn testing. Language-agnostic; Go examples. Use when designing or reviewing a gRPC service.
Skill Claude CodeCodex
MCP (Model Context Protocol) 2026-07-28 server standards — tool/resource/prompt primitives, stateless protocol core (no initialize handshake, no Mcp-Session-Id), Mcp-Method/Mcp-Name header routing, Multi Round-Trip Requests (MRTR) for elicitation/sampling, cacheable list results (ttlMs/cacheScope), OAuth 2.1 + RFC…
Skill Claude CodeCodex
Cross-language REST conventions — resource URLs, method semantics, status codes, URL-prefix versioning, cursor pagination, snakecase JSON, ISO 8601 timestamps, RFC 7807 errors, Idempotency-Key, ETag/If-Match, OpenAPI as source of truth. Framework-agnostic. Use when designing or auditing REST endpoints.
Skill Claude CodeCodex
Reviews REST + gRPC contracts for stability, versioning, completeness, backwards compatibility. References rest-api-architect / protobuf-architect / grpc-architect for rules; runs buf breaking / openapi-diff. Severity-keyed findings. Use when reviewing a new endpoint, proto change, or before a breaking-change release.
Skill Claude CodeCodex
Cross-language perf review — N+1, missing indexes, blocking I/O in async, allocation hot paths, unbounded memory, slow algorithms. Findings grounded in EXPLAIN / pprof / py-spy / metrics. Use when reviewing for perf or investigating a slow endpoint.
Skill Claude CodeCodex
Cross-language security review — injection, auth/authz, secrets, insecure defaults, deserialization, CSRF/SSRF/IDOR, dep vulns. Emits a Critical/High/Medium/Low report with file:line + fixes. Use when auditing a PR or pre-release.
Skill Claude CodeCodex
Design-level refactoring rules — extraction, decoupling, SRP, encapsulation, primitive obsession. Language-agnostic. Sits between logic-cleaner (expression-level) and improve-codebase-architecture (system-level). Use when restructuring existing code at the module/class/function level.
Skill Claude CodeCodex
Skeptical design-patterns reference catalog for modern Go and Python — keeps repository, adapter, strategy, decorator, observer, builder; flags the rest as anti-patterns. Consultative, not active: consult before introducing a pattern in code-design-refactor or improve-codebase-architecture, or when pushing back on a…
Skill Claude CodeCodex
Find deepening opportunities in a codebase, informed by the domain language in CONTEXT.md and the decisions in docs/adr/. Use when the user wants to improve architecture, find refactoring opportunities, consolidate tightly-coupled modules, or make a codebase more testable and AI-navigable.
Skill Claude CodeCodex
Expression-level code cleanup — guard clauses, naming, magic values, conditional simplification, duplication. Language-agnostic. Out of scope: architecture, module decomposition. Use when user asks to clean code, simplify expressions, flatten nesting, or invokes /logic-cleaner.
Skill Claude CodeCodex
ROS2 standards across Jazzy/Kilted/Lyrical — colcon + amentcmake/amentpython layout, lifecycle nodes, explicit QoS, services/actions, parameters, Python launch DSL. Cross-platform dev env via Pixi + RoboStack. C++ (rclcpp) and Python (rclpy) equal first-class. Use when scaffolding or reviewing a ROS2 workspace.
Skill Claude CodeCodex
Cross-language CLI standards — subcommand structure, flag/env/config/default precedence, TOML in XDG, stdout-data/stderr-logs split, --output json|yaml, exit codes, NOCOLOR, completions. Go (cobra+pflag+viper) and Python (typer) recipes. Use when designing or reviewing a CLI.

At most 3 mods per repository are shown here, and a mod shipped inside a plugin is left to that plugin's page — the rest are on their repository pages:
