  2. Caveman · arndvs
    Ultra-compressed conversational replies — drops articles, filler, and hedging to cut output tokens while keeping full technical accuracy. Deliverables (plans, PRDs, issues, docs, commits, code) always stay normal prose; only the surrounding narration compresses. Use when asked to 'talk like caveman', 'caveman mode', 'be terse', 'fewer tokens', 'compress your replies', or invokes /caveman.

  14. Agent Assets · arndvs bundle
    Audit the agentic infrastructure committed to a repo — reusable commands, autonomous workflows, vendored documentation, and tool or MCP configuration — and propose what to add, consolidate, or retire. Use when the same prompt is being retyped across sessions, when agent workflows exist but nobody can tell whether they ran or what they did, when orientation files have gone stale or contradict the code, when agents repeatedly fetch the same external docs, or when planning to move work from interactive prompting to scheduled autonomous runs. Also use for requests like "what should be a slash command", "review our .claude directory", "why do our agent workflows keep silently failing", or "audit our AGENTS.md".

  18. Repo Hygiene · arndvs bundle
    Drives a long-running, incremental refactor of a messy codebase toward reusable layouts, extracted components, and clean structure. Use whenever the task involves auditing a repo for structural debt, planning the next step of a multi-week refactor, or generating a single well-scoped backlog issue for automated/nightly refactor runs. Also use it when asked to clean up huge monolithic pages, extract layouts or components, migrate page CSS to Tailwind, set up a repeating refactor workflow, or 'improve repo hygiene'. Stack-aware: dispatches to Astro, static-HTML, Worker-TS, or Python audits automatically. Trigger even if the user only says 'what should I clean up next' about a project.

  19. Logging Audit · arndvs bundle
    Audit code for logging and observability quality, retrofit code onto whatever logger a repo already uses, and diagnose why a failed run left no usable evidence. Use this whenever reviewing a diff or PR for log quality, cleaning up or standardising logging in a module, judging whether error handling would actually be diagnosable in production, deciding what a catch block should do, or running a postmortem on a job or agent run that failed without explaining itself. Works in any language and any repo. Trigger it for requests like "review the logging here", "why was this run impossible to debug", "is this catch block okay", "make this failure easier to trace", or any investigation of a job that died silently — even when the user never says the word "logging".

  24. Grill With Docs · arndvs bundle

  25. Visual Feedback · arndvs
    Use when implementing UI, checking dark/light mode, or validating animations — adds a visual feedback loop via browser screenshots so frontend changes are verified, not assumed.

  26. Compliance Audit · arndvs
    Auto-invoke after any do-work, tdd, systematic-debugging, or review-pr-copilot task completes to review the diff against active rules and skills, flag violations, update the skill if a gap is found, and close the loop between 'rule was loaded' and 'rule was followed'.

  27. Skill Scaffolder · arndvs bundle
    Meta-skill for creating new agent skills that involve multi-step automation, browser navigation, state tracking, evidence capture, and both local (VS Code Insiders) and VPS (Playwright) execution. Use when the user wants to 'create a skill', 'build a new skill', 'scaffold a skill', 'make a skill for X', or describes a multi-step agentic workflow they want to automate.

  28. Agent Testability · arndvs bundle
    Audit whether a codebase gives a coding agent a reliable way to verify its own work, and propose fixes. Use whenever an agent reports success but the change is broken, when tests exist but don't catch regressions, when the feedback loop is too slow or too noisy for an agent to use, when test failures don't say what broke, or when someone asks how to make a repo safe for autonomous or unattended agent runs. Also use for requests like "why does it keep saying it's done when it isn't", "review our test setup for agents", "what should agents run before opening a PR", or planning a testing strategy where the consumer is an agent rather than a human.

  29. Performance Audit · arndvs

  31. Agent Navigability · arndvs bundle
    Audit a codebase for how easily a coding agent can navigate it, and propose structural fixes. Use this whenever an agent keeps re-exploring the same code, burns context finding where things live, edits the wrong file, or misses call sites it should have found; when reviewing structure, naming, module boundaries, or type usage for legibility rather than correctness; when onboarding cost is high for agents or new engineers; or when someone asks why agent runs on this repo are slow, expensive, or unreliable. Also use for requests like "restructure this for agents", "why does it keep missing files", "review our naming", or planning a refactor whose goal is comprehension rather than behaviour. Includes a migration mode for repo-wide restructuring such as separating client from server, splitting a monolith, or changing the top-level layout, which produces a phased plan rather than a findings list.

  38. Agent Session Friction · arndvs bundle
    Analyse a completed agent session transcript for evidence that the codebase made the work harder than it needed to be, and record those observations for later consolidation. Use at the end of an agent run, when reviewing a transcript to find what slowed an agent down, when deciding which repo problems are actually costing something, or when someone asks why a run took so many turns or burned so much context. Also use for requests like "audit this session", "what friction did this run hit", "post-run review", or when building automation that collects friction evidence across many runs. Produces observations with measured cost, not issues — publishing is a separate consolidation step.

  39. Data Object Conventions · arndvs bundle
    Enforce consistent structure, formatting, and placement for static data objects (catalogs, config, content, lookup tables, enums-as-data) in TypeScript/JavaScript codebases. Use whenever creating, editing, refactoring, or reviewing a data file or data object — including extracting data out of logic files, splitting a monolithic file, deciding where data should live, or formatting a data array. Triggers on phrases like 'data file', 'data object', 'catalog', 'lookup table', 'extract the data', 'split this file', 'format this data', 'where should this data live', 'this data is ugly'. Do NOT use for runtime state, API responses, or database rows — those are data-in-motion, not static data.
