Install

Skills CLI

npx skills add SethGammon/Armory

Asks which skills and agents to install. Just one: npx skills add SethGammon/Armory --skill ascii-diagram — add -g for every project.

Claude Code

git clone https://github.com/SethGammon/Armorycp -r "Armory/ascii-diagram" ~/.claude/skills/

Copies the ascii-diagram skill into ~/.claude/skills/ for every project (use .claude/skills/ for one project). Repeat for the other skills listed below.

Plugin

/plugin marketplace add SethGammon/Armory

Run inside Claude Code if the repository ships a plugin marketplace, then pick plugins from /plugin.

Skills can run code on your machine — read the SKILL.md first.

What it does

In the author's own words, from each skill's SKILL.md.

  • ascii-diagram

    Generate perfectly aligned ASCII diagrams — architecture, flow, sequence, box-and-arrow. Uses a programmatic character-grid approach so alignment is guaranteed by math, not token prediction. Includes post-render verification.

    ascii-diagram/SKILL.md on GitHub (opens in a new tab)
  • doc-gen

    Documentation generator with three modes: function-level (JSDoc/docstrings), module-level (directory READMEs), and API reference (endpoints/exports). Reads existing project doc style and matches it. Never generates docs that just restate what the signature already says.

    doc-gen/SKILL.md on GitHub (opens in a new tab)
  • experiment

    Automated optimization loop with scalar fitness function. Proposes changes in isolated worktrees, measures with a metric command, keeps improvements, discards failures. Supports convergence detection and diminishing returns.

    experiment/SKILL.md on GitHub (opens in a new tab)
  • live-preview

    Mid-build visual verification loop. Takes screenshots of components during construction, not just after. Catches visual regressions and invisible features before they compound. Requires Playwright or similar screenshot tool.

    live-preview/SKILL.md on GitHub (opens in a new tab)
  • qa

    Browser-based QA verification. Launches a real browser, navigates the app, clicks buttons, fills forms, and tests user flows. Works as a standalone skill or as a phase end condition in campaigns. Requires Playwright (optional dependency, graceful skip if not installed).

    qa/SKILL.md on GitHub (opens in a new tab)
  • refactor

    Safe multi-file refactoring with automatic rollback. Establishes a type/test baseline, plans all changes, executes file-by-file, and verifies zero regressions. Reverts if verification fails after two fix attempts. Handles renames, extracts, moves, splits, merges, and inlines.

    refactor/SKILL.md on GitHub (opens in a new tab)
  • research-fleet

    Parallel research using Fleet wave mechanics. Spawns multiple scout agents, each investigating a different angle of the same question. Findings are compressed between waves. Produces a unified research brief from multiple independent perspectives.

    research-fleet/SKILL.md on GitHub (opens in a new tab)
  • research

    Focused research investigations. Converts questions into structured findings with confidence levels and source citations. Does not make decisions — produces information that informs the next step.

    research/SKILL.md on GitHub (opens in a new tab)
  • review

    5-pass structured code review — correctness, security, performance, readability, consistency

    review/SKILL.md on GitHub (opens in a new tab)
  • scaffold

    Project-aware file generation. Reads existing codebase conventions (naming, structure, imports, exports, test patterns) then generates new files that match exactly. Wires generated files into the project's registration points.

    scaffold/SKILL.md on GitHub (opens in a new tab)
  • session-handoff

    Synthesizes the current session into a structured HANDOFF block for context transfer between sessions. Captures what was built, decisions made, and unresolved items.

    session-handoff/SKILL.md on GitHub (opens in a new tab)
  • systematic-debugging

    4-phase root cause analysis: observe, hypothesize, verify, fix. Enforces investigation before any code changes. Emergency stop after 2 failed fixes. Prevents shotgun debugging and fix cascades.

    systematic-debugging/SKILL.md on GitHub (opens in a new tab)
  • test-gen

    Generate and verify tests — happy path, edge cases, error paths — using the project's own framework and patterns

    test-gen/SKILL.md on GitHub (opens in a new tab)
  • triage

    GitHub issue and PR investigator. Pulls open issues/PRs, classifies them, searches the codebase for root cause or reviews contributed code, proposes fixes with file:line references, and optionally implements fixes. Handles both issues and pull requests.

    triage/SKILL.md on GitHub (opens in a new tab)

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.
