Create or update a reusable Agent Skill in the open SKILL.md format. Use for project, team, domain, or tool workflows that need a precise trigger and repeatable procedure. Add references, scripts, assets, client metadata, or routing only when the skill needs them; do not create a new skill for a one-off instruction or…
Skill Claude CodeCodex
Check project dependencies, base images, operating-system packages, infrastructure providers, plugins, and agent tools against current vulnerability and active-exploitation sources. Use before release, after dependency changes, during incident review, and on a schedule for long-lived services. Record source…
Skill Claude CodeCodex
Design or review data, analytics, ML, embedding, vector-search, RAG, and model-lifecycle pipelines. Use when the product depends on sourced data, schemas, transformation, training, evaluation, deployment, lineage, drift detection, or retraining. Produce data contracts, reproducibility requirements, evaluation…
Skill Claude CodeCodex
Break approved product scope and architecture artifacts into epics, user stories, implementation tasks, dependency graph, critical path, ownership map, validation packs, merge order, and parallelization plan. Use after requirements and architecture are approved and before assigning implementation agents, opening…
Skill Claude CodeCodex
Use for broad DevOps, infrastructure, deployment, automation, operations, security, incident, cloud, Kubernetes, CI/CD, container, IaC, scripting, observability, or network/VPN requests that need safe routing before implementation.
Skill Claude CodeCodex
Maintain project documentation and Obsidian-first knowledge graph using Markdown notes, wikilinks, ADRs, artifact indexes, Mermaid diagrams as visual layer, change logs, and graph hygiene. Use when syncing docs after code changes, creating a project vault skeleton, updating project memory, linking requirements to…
Skill Claude CodeCodex
Review the maintainability of production code and guide focused refactoring through clear names, cohesive modules, explicit dependencies, controlled side effects, actionable errors, readable tests, and small change sets. Use during implementation planning, code review, legacy cleanup, or a refactor where behavior must…
Skill Claude CodeCodex
Convert a design choice, architecture option, market assumption, or feature bet into a falsifiable hypothesis with a measurable kill criterion, the cheapest useful test to settle it, and a clear record of what was supported, disproved, or deferred. Use whenever the agent is tempted to commit to a stack, a pattern, a…
Skill Claude CodeCodex
Design or review localization for a product that supports more than one language or region. Use before visible strings and layouts become difficult to change and before release. Cover source strings, message formats, plural rules, RTL and CJK layouts, glossary, translation workflow, locale-specific QA, accessibility…
