Skill Claude CodeCodex
How a meta-engineer improves an autonomous AI engineer from the OUTSIDE — mining the agent's own operational telemetry across many runs and, where a deployment runs more than one instance, across all of them. Scores the agent on reliability, safety, efficiency, outcome throughput, quality, coordination and currency…
Skill Claude CodeCodex
Helps users discover and install agent skills when they ask questions like "how do I do X", "find a skill for X", "is there a skill that can...", or express interest in extending capabilities. This skill should be used when the user is looking for functionality that might exist as an installable skill.
Skill Claude CodeCodex
The run loop for an autonomous AI engineer acting as a portfolio's primary engineer — pre-flight, resume in-flight work or survey every product's live state, select the highest-value work (operate before advance), act through isolated per-run working copies and draft PRs self-promoted on genuine readiness (driving…
Skill Claude CodeCodex
The ADVANCE playbook for an autonomous AI engineer — how to move a product forward once it is healthy: product strategy and roadmap stewardship, issue triage and decomposition, oldest-actionable-first implementation, test coverage, benchmarking and performance, refactoring and code quality, documentation sync, and…
Skill Claude CodeCodex
How an autonomous AI engineer improves its OWN definition (its engineering contract, agent definitions, and skills) over time — capturing operational learnings from every run and distilling them into evidence-based, guard-railed draft PRs self-promoted on genuine readiness. Use at the end of every run (to log…

Supports: (1) Auto-detecting type and scope from changes, (2) Generating conventional commit messages from diff, (3) Interactive…
Skill Claude CodeCodex
Surgical code refactoring to improve maintainability without changing behavior. Covers extracting functions, renaming variables, breaking down god functions, improving type safety, eliminating code smells, and applying design patterns. Less drastic than repo-rebuilder; use for gradual improvements.
Skill Claude CodeCodex
Use when implementing any feature or bugfix, before writing implementation code.

Use when users ask how to write, explain, customize, migrate, secure, or troubleshoot GitHub Actions workflows, workflow syntax, triggers, matrices, runners, reusable workflows, artifacts, caching, secrets, OIDC, deployments, custom actions, or Actions Runner Controller, especially when they need official GitHub…
Skill Claude CodeCodex
Create, update, and manage GitHub issues using MCP tools. Use this skill when users want to create bug reports, feature requests, or task issues, update existing issues, add labels/assignees/milestones, set issue fields (dates, priority, custom fields), set issue types, manage issue workflows, link issues, add…
Skill Claude CodeCodex
Debug and troubleshoot Flux CD on live Kubernetes clusters (not local repo files) via the Flux MCP server — inspects Flux resource status, reads controller logs, traces dependency chains, and performs installation health checks. Use when users report failing, stuck, or not-ready Flux resources on a cluster…
Skill Claude CodeCodex
Flux CD and Flux Operator expert — answers questions and generates schema-validated YAML for all Flux CRDs (not repo auditing or live cluster debugging). Use when users ask about Flux concepts, want manifests for HelmRelease, Kustomization, GitRepository, OCIRepository, ResourceSet, FluxInstance, or any Flux resource.…
Skill Claude CodeCodex
Audit and validate Flux CD GitOps repositories by scanning local repo files (not live clusters) — runs Kubernetes schema validation, detects deprecated Flux APIs, reviews RBAC/multi-tenancy/secrets management, and produces a prioritized GitOps report. Use when users ask to audit, analyze, validate, review, or…
Skill Claude CodeCodex
Onboard a new tenant application onto a Flux-based GitOps platform: scaffold the tenant repo's deploy manifests, wire OpenBao/Vault secrets via External Secrets, fit the cluster's Kyverno/PodSecurity and default-deny network policies, expose the app through a shared Gateway API gateway, and register the tenant on the…
Skill Claude CodeCodex
Implements concurrent Go patterns using goroutines and channels, designs and builds microservices with gRPC or REST, optimizes Go application performance with pprof, and enforces idiomatic Go with generics, interfaces, and robust error handling. Use when building Go applications requiring concurrent programming…
Skill Claude CodeCodex
Before agreeing to build anything for a non-technical user, check the need against the consuming deployment's "## Stack map" section: in-stack needs proceed; out-of-stack or unmatched needs get a friendly, jargon-free decline plus an offer to file a well-formed issue on the block's owning repo (or the map's default…
Skill Claude CodeCodex
The conversational register for assisting a non-technical person who is building a product by conversation alone: plain language with no technical vocabulary by default, technical terms only on request and always explained in common words, and progress reported as product outcomes rather than engineering artifacts.…
Skill Claude CodeCodex
Translate a non-technical person's plain-language product needs (an outcome, an audience, a workflow) into the deployment's technical building blocks behind the scenes, keeping the conversation entirely in the user's vocabulary. Reads the consuming deployment's "## Stack map" section to learn what each building block…
