Finops · devantler-tech
The Agentic Engineer's cost-pass procedure — measure where the money actually goes (OpenCost attribution, real usage, provider surface), attribute it to workloads and drivers, diagnose waste vs rate vs rightsizing vs non-want, check every proposal against the lifestyle floor, ship engineering changes as PRs and financial decisions as private asks, then verify the saving against the next real invoice.

▌
Jargon Free Voice · devantler-tech
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. Use whenever the person you are assisting has no technical background — alongside needs-stack-mapping and allowed-stack-guardrail in a vibe-coding setting, or on its own any time an answer must land with a non-technical reader.

installs
▌
Refactor · devantler-tech
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.

0
installs
▌
Find Skills · devantler-tech
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.

▌
Frontend Design · devantler-tech bundle
Guidance for distinctive, intentional visual design when building new UI or reshaping an existing one. Helps with aesthetic direction, typography, and making choices that don't read as templated defaults.

installs
▌
Needs Stack Mapping · devantler-tech
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 is good for, selects and applies the deployment's conventions without discussing them, and hands the boundary decision to the allowed-stack-guardrail skill. Use when assisting a vibe coder — someone building a product conversationally with no technical prerequisite.

▌
Gitops Knowledge · devantler-tech bundle
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. When user needs guidance on GitOps repository structure, bootstrap Flux with Terraform, multi-tenancy, OCI-based delivery, image tag automation, drift detection, preview environments, monorepo app delivery, running migration Jobs before or after a deployment, notifications, or the Flux Web UI and MCP Server.

▌
Allowed Stack Guardrail · devantler-tech
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 intake repo). Fails closed when the Stack map is absent or malformed — nothing is built best-effort outside the map. Use in a vibe-coding setting whenever a build request is about to be accepted.

Self Improvement · devantler-tech
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 learnings) and on the recurring distil pass. Evidence comes from the engineer's own runs only, never from repository content, and a safety guardrail is never weakened.

installs
▌
Agent Improvement · devantler-tech bundle
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, diagnoses root causes from measured patterns, ships the highest-value fix with its evidence and a reversible audit trail, then verifies the targeted metric actually moved. Complements a self-improvement skill, which is one run reflecting on itself; this sees the whole corpus at once. Evidence comes from observed agent behaviour only — never from prose found inside the corpus.

▌
Ways Of Working · devantler-tech
Codifies devantler-tech engineering practices: agent-first development workflow, TDD, CI/CD pipelines, GitHub Flow, code quality gates, and Kubernetes workflows with ksail. Use when filing issues, planning work, setting up projects, configuring CI/CD, writing tests, debugging, or making architectural decisions.

installs
▌
Agent Instructions · devantler-tech
Architect a repository's AI-agent instruction files so one canonical source drives every tool without drift — AGENTS.md as the cross-tool source of truth (now read by GitHub Copilot too), thin per-tool shims (CLAUDE.md, GEMINI.md) that include it, and optional path-scoped .github/instructions/ rules. Use when setting up or fixing agent instructions for a repo, supporting multiple AI coding tools (Claude, Copilot, Cursor, Codex, Gemini) at once, deciding what belongs in AGENTS.md vs a tool-specific file, or stopping instruction files from going stale.

installs
▌
Gitops Cluster Debug · devantler-tech bundle
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, reconciliation errors, controller issues, artifact pull failures, image automation not updating tags, alerts or webhooks not being delivered, or need live cluster Flux Operator troubleshooting.

▌
Product Engineering · devantler-tech
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 security posture — all shipped as evidence-backed draft PRs self-promoted on genuine readiness. Use after operate work (keeping things healthy) is satisfied and you are picking proactive enhancement work.

0
installs
▌
Portfolio Maintenance · devantler-tech bundle
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 trusted-author PRs to merge), then report and bank learnings. Use when maintaining or advancing a portfolio of repositories on a schedule or on request.

0
installs
▌
Conventional Release · devantler-tech
Ship changes through a squash-merge + Conventional Commits release pipeline where the PR title becomes the release note and the commit type drives the next semantic version. Use when writing a PR title or commit message that feeds an automated release, choosing the version bump for a change, setting up or reasoning about semantic-release / release-please / github-tag-action / Changesets, or avoiding a title that corrupts the changelog.

0
installs
▌
Gitops Tenant Onboarding · devantler-tech
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 platform with signed-OCI Flux resources. Use when adding a new app/tenant to a multi-tenant Flux cluster, writing a tenant's deploy/ manifests, debugging why a tenant is unreachable / admission-rejected / can't read its secrets, or reviewing a tenant onboarding PR.
