justfile-author

Use this skill when authoring or refactoring a justfile (and matching Makefile wrapper) for one of Nick's projects. Triggers when the user asks to "create a justfile", "add a justfile to this project", "set up just for…", "wire up tmux services", "scaffold the task runner", or when working in a repo that lacks a justfile but obviously needs one. Produces a justfile using zsh syntax with the standard svc-* tmux service family, the canonical build/lint/dev/test recipes, a thin Makefile passthrough wrapper that auto-installs just, and per-service tx-start.sh helpers. Do NOT use for editing existing third-party justfiles or non-Nick projects unless the user explicitly opts in.

UncategorizedView skill →

knowledge-stack

Use this skill whenever working inside any of Nick's repos (under ~/Developer/) or whenever a conversation touches Nick's durable cross-cutting work — Atlas Crew product strategy/brand/planning, the Unanet job, job search, interviews, tax amendment, foreclosure/tenant situation, strategic positioning. Maps Nick's three Basic Memory projects (products, work, main) and the per-repo dev trackers, and says which layer owns which kind of question. Consult before reasoning from stored memory summaries about repo architecture, product decisions, active priorities, or ongoing personal/career state — stored memory is lossy; the trackers and the Basic Memory projects are the real artifacts and should be consulted first.

UncategorizedView skill →

UncategorizedView skill →

mapping-suite

User-triggered orchestrator that walks the user through running multiple sibling mapping/audit/doc skills against a shared scope, then assembles their outputs into one navigable artifact. Coaches rather than auto-runs — at each step the orchestrator presents the next sibling skill, recommended scope inheritance, and approval gate; the user invokes the sibling and confirms before moving on. Resolves the prior arch-analysis lookup once at suite start so every sibling skill inherits the same scope. Records each run's output path in a suite manifest. Produces a combined navigation HTML that links to each sibling's standalone HTML for one-stop sharing. Ships two named recipes — "release-driver onboarding" (for tooling that drives releases) and "deployed-system onboarding" (for systems that get deployed) — and supports custom plans. Trigger on "run our mapping suite," "do a complete onboarding," "build the combined report," "I need to onboard to system X," "give me the full picture of this codebase," or when the user names two-or-more sibling analyses to coordinate. Not for running a single sibling skill in isolation (invoke it directly), and not for bypassing approval gates (this skill coaches, never autoruns).

UncategorizedView skill →

market-researcher

Use this skill when sizing a market, analyzing competitors, designing customer surveys, segmenting audiences, or synthesizing research into market insights. Trigger phrases: ''size the market for'', ''analyze our competitors'', ''who is our target customer'', ''design a survey to understand'', ''TAM/SAM/SOM for''. Not for building financial models, writing pitch decks, or conducting UX usability research.

UncategorizedView skill →

multi-llm-consult

UncategorizedView skill →

multi-specialist-review

User-triggered multi-agent code review. Spawns 3-5 parallel specialist sub-agents that read actual source files, runs mechanical citation verification, and synthesizes a single review artifact. Use for PR-level changes, multi-commit ranges, or security-sensitive work where single-turn review is insufficient.

proofreader

Use this skill when reviewing written content for grammar, spelling, punctuation, style consistency, and tone—before publishing, submitting, or sending. Trigger phrases: ''proofread this'', ''check my writing'', ''review this for errors'', ''edit this email/report/essay''. Do NOT use when structural rewrites or content changes are needed—proofreading fixes surface errors, not substantive problems.
