    skills/golang-best-practices/SKILL.md on GitHub (opens in a new tab)
  • grill

    Adversarial questioning and collaborative shaping in one skill. Two modes: stress-test (challenge a plan/design until gaps surface) and shape (iterate on requirements and solution options until alignment). Use when user says 'grill me', 'stress-test this', 'challenge this plan', 'shape this', 'let's explore options', or wants to pressure-test any design before committing.

    skills/grill/SKILL.md on GitHub (opens in a new tab)
  • handoff

    Compact the current session into a handoff document for another agent or future session to pick up. Captures mission, repo state, role, scope, locked decisions, dispatch sequence, and a pickup checklist. Studio-aware. Use when pausing work, ending a session, switching contexts, or preparing for a fresh agent to continue.

    skills/handoff/SKILL.md on GitHub (opens in a new tab)
  • kickoff

    Initialize a new project with PROJECT.md + ROADMAP.md in .project/, set up jira and studio, and route to the first sprint. Use when starting a new project, onboarding a new codebase, or setting up workflow infrastructure for the first time.

    skills/kickoff/SKILL.md on GitHub (opens in a new tab)
  • localframe

    Record silent product demos on this machine: a paced Playwright browser walkthrough of a web app or docs site, or a scripted asciinema terminal session against an API, rendered to mp4 with numbered stills, a listing paragraph, and the shot list committed beside it. Gated so nothing is published until the demo key is revoked and the artefacts grep clean. Use when the user says 'record a demo of X'…

    skills/localframe/SKILL.md on GitHub (opens in a new tab)
  • nestjs-best-practices

    NestJS best practices and architecture patterns for building production-ready applications. This skill should be used when writing, reviewing, or refactoring NestJS code to ensure proper patterns for modules, dependency injection, security, and performance.

    skills/nestjs-best-practices/SKILL.md on GitHub (opens in a new tab)
  • orchestrator

    Turn the current session into a chief-of-staff thread that runs a war room of three role slots — surveyor, executor, auditor — and routes per-branch work to durable, reusable child agents. Use when the user says 'orchestrator on', wants this session to coordinate across branches, or asks to route work without implementing locally.

    skills/orchestrator/SKILL.md on GitHub (opens in a new tab)
  • pdf

    Use this skill whenever the user wants to do anything with PDF files. This includes reading or extracting text/tables from PDFs, combining or merging multiple PDFs into one, splitting PDFs apart, rotating pages, adding watermarks, creating new PDFs, filling PDF forms, encrypting/decrypting PDFs, extracting images, and OCR on scanned PDFs to make them searchable.

    skills/react-best-practices/SKILL.md on GitHub (opens in a new tab)
  • retro

    Use when a user completes a phase, sprint, milestone, or meaningful unit of work and needs a retrospective. Also triggers on `/retro` command. Generates honest, structured retrospectives from available project data (GSD planning files, git history, GitHub PRs/issues, user input). Adapts to any project — GSD-managed, plain git repos, GitHub-heavy workflows, or unstructured projects. Jira-aware: de…

  • rust-best-practices

    Guide for writing idiomatic Rust code based on Apollo GraphQL's best practices handbook. Use this skill when: (1) writing new Rust code or functions, (2) reviewing or refactoring existing Rust code, (3) deciding between borrowing vs cloning or ownership patterns, (4) implementing error handling with Result types, (5) optimizing Rust code for performance, (6) writing tests or documentation for Rus…

    skills/rust-best-practices/SKILL.md on GitHub (opens in a new tab)
  • skill-creator

    Guide for creating effective skills. Use when creating a new skill, updating an existing skill, or verifying skills work before deployment. Covers skill structure, creation process, testing methodology, and packaging.

    skills/skill-creator/SKILL.md on GitHub (opens in a new tab)
  • spawn

    Fan out work to parallel sub-agents with worktree isolation. Reads a plan, scope list, or inline description, breaks it into waves of independently-dispatchable units, and coordinates execution. The coordinator never implements — it dispatches. Use when user says 'spawn', 'fan out', 'parallelize', 'dispatch waves', or has multiple independent tasks to dispatch.

    skills/spawn/SKILL.md on GitHub (opens in a new tab)
  • tower

    Run the orchestrator's war room on visible Herdr panes so the user can watch every child agent work. Use when the user says 'tower on', 'orchestrate this in herdr', wants routed agents they can see, or when the orchestrator is on inside a Herdr-managed pane.

    skills/tower/SKILL.md on GitHub (opens in a new tab)
  • wildcard-proxy

    Set up Caddy on a server so any local port is reachable at https://<port>.<domain>/, and two-letter or named labels like https://ui.<domain>/ map to ports too, with certificates issued on demand and gated so only routed hostnames get one. Use when the user says 'set up the wildcard proxy', 'port routing on this server', 'configure caddy so ports get subdomains', 'add a short name for port N', 'wh…

    skills/wildcard-proxy/SKILL.md on GitHub (opens in a new tab)
  • xlsx

    Use this skill any time a spreadsheet file is the primary input or output. This means any task where the user wants to: open, read, edit, or fix an existing .xlsx, .xlsm, .csv, or .tsv file (e.g., adding columns, computing formulas, formatting, charting, cleaning messy data); create a new spreadsheet from scratch or from other data sources; or convert between tabular file formats. Trigger especia…

    skills/xlsx/SKILL.md on GitHub (opens in a new tab)
  • architect

    Sketch types, signatures, and module structure before code, then stay in the loop while implementation fills in. Use for /architect, 'architect this', 'design this', or non-trivial work where jumping to code would lock in the wrong shape.

    plugins/pstack/skills/architect/SKILL.md on GitHub (opens in a new tab)
  • arena

    Spawn N parallel candidates at the same task, pick a base, graft the strongest parts of the losers into it. Use for /arena, 'arena this', 'throw it in the arena', or when one attempt at a non-trivial artifact would lock in the wrong shape.

    plugins/pstack/skills/arena/SKILL.md on GitHub (opens in a new tab)
  • automate-me

    Use for "automate me", "create/update/refresh my -mode skill", "turn/capture my preferences or working style into a skill", or wanting agents to follow how the user works. Drafts or revises a personal -mode skill via skill-creator + unslop, optionally pulling fresh evidence from recent transcripts.

    plugins/pstack/skills/automate-me/SKILL.md on GitHub (opens in a new tab)
  • benchmark-checklist

    Vet a perf measurement (limiter, tuning, limits, errors, repeatability, relevance, and whether the work happened) before you report or act on it. Use when you run a benchmark or report a speedup or regression you measured.

    plugins/pstack/skills/benchmark-checklist/SKILL.md on GitHub (opens in a new tab)
  • blast-radius

    Find what a change could break somewhere else before it ships, beyond the diff, and prove the one fact it's safe because of by running real code instead of writing it up. Use for 'blast radius of X', 'what could this break', or reviewing a small diff you don't trust.

    plugins/pstack/skills/blast-radius/SKILL.md on GitHub (opens in a new tab)
  • bro

    Restate the last message in plain human language, with no jargon.

    plugins/pstack/skills/bro/SKILL.md on GitHub (opens in a new tab)
  • correct

    Find the mistakes agents keep repeating in this repo and make each one impossible. Try architecture first, then types, then a lint whose error names the fix, then a test, and write docs last. Prove each check fails on a real past mistake. Repeat this each time the operator corrects you. Use for /correct.

    plugins/pstack/skills/correct/SKILL.md on GitHub (opens in a new tab)
  • create-verification-skill

    Generate a project-local verification skill that drives your app the way a user does — any language, framework, or platform. Use for /create-verification-skill, "make a control skill for this repo", or when a project has no scripted way to prove UI/CLI/service behavior.

    plugins/pstack/skills/create-verification-skill/SKILL.md on GitHub (opens in a new tab)
  • figure-it-out

    Design an auditable playbook when no narrower one fits: a large migration, an ambitious multi-part change, or work a human reviews after stepping away. Scales rigor to the task, runs a hypothesis loop, and logs decisions. Use for /figure-it-out or 'figure it out'.

Review before you install

A skill is a set of instructions and scripts your agent will follow, and it can run code on your machine. Read the SKILL.md and any scripts first — this listing is not a security review.
