Claude Code
git clone https://github.com/instructa/agent-skillscp -r "agent-skills/skills/3d-gaming/unity-docs" ~/.claude/skills/
Copies the unity-docs skill into ~/.claude/skills/ for every project (use .claude/skills/ for one project). Repeat for the other skills listed below.
Plugin
/plugin marketplace add instructa/agent-skills
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.
-
unity-docs
Resolve Unity signatures, deprecations, package APIs and behavior using local evidence and official docs.
skills/3d-gaming/unity-docs/SKILL.md on GitHub (opens in a new tab) -
codex-reviewer
Have Codex review a feature or change from Claude Code, then let Claude address the findings and request verification. Use for an independent review of implementation, acceptance criteria, architecture, or UI evidence while Claude remains the implementer.
skills/claude/codex-reviewer/SKILL.md on GitHub (opens in a new tab) -
claude-designer
Use Claude Code directly from Astra's current task to design or implement UI/UX and frontend work, with Astra owning sequencing, review, and integration. Use when the user invokes $claude-designer or requests this workflow.
skills/codex/claude-designer/SKILL.md on GitHub (opens in a new tab) -
redesign-my-landingpage
Build, critique, and iterate high-converting marketing or product landing pages using React + Vite + TypeScript + Tailwind and shadcn/ui components, with all icons sourced from Iconify. Use when the user asks for a landing page, sales page, signup page, CRO improvements, above-the-fold vs below-the-fold structure, hero + CTA copy, section order, or wants production-ready shadcn + Vite code.
skills/design/redesign-my-landingpage/SKILL.md on GitHub (opens in a new tab) -
electron-live-test
Live-test any Electron desktop app with native-devtools-mcp, Chrome DevTools Protocol, screenshots, OCR, and accessibility tools. Use when the user asks for Electron UI verification, MCP-driven app control, renderer CDP interaction, native desktop automation, screenshots, or OCR-driven checks.
skills/electron/electron-live-test/SKILL.md on GitHub (opens in a new tab) -
architecture-ownership
Determine runtime owner, first-fix layer, and canonical long-term module or package owner in layered codebases. Use when placing code across UI vs platform shell vs runtime orchestration vs domain or application vs shared core vs adapter or integration layers, debugging ownership issues, removing duplicate policy paths, or answering "where should this live?" architecture questions.
skills/engineering/architecture-ownership/SKILL.md on GitHub (opens in a new tab) -
clarify
Turn complex, technical, ambiguous, or verbose material into clear language without losing important detail. Use when the user asks to simplify an answer, identify what matters, compare options, recommend an action, or make the next step explicit.
skills/engineering/clarify/SKILL.md on GitHub (opens in a new tab) -
code-quality
Apply focused code-quality checks when implementing or reviewing behavioral changes. Use for maintainability, framework fit, data safety and meaningful verification; not visual design or a full security audit.
skills/engineering/code-quality/SKILL.md on GitHub (opens in a new tab) -
consolidate-test-suites
Decide where durable test coverage belongs and clean up temporary test probes. Use while testing a bug fix or architectural change, or before finishing work that added tests, fixtures, snapshots, diagnostics, or temporary assertions. Select one owning layer, reuse canonical suites, merge unique signal, and remove task-created probe residue without disturbing pre-existing work.
skills/engineering/consolidate-test-suites/SKILL.md on GitHub (opens in a new tab) -
find-duplicate-ownership
Find duplicate ownership, hidden second sources of truth, and contract drift in layered codebases. Use when reviewing normalization, validation, defaulting, canonicalization, persistence mapping, runtime-vs-durable state, duplicated helpers, query or cache ownership, or any "who owns this rule?" architecture question. Especially useful for SSOT audits across frontend, backend, shared core, and ad…
skills/engineering/find-duplicate-ownership/SKILL.md on GitHub (opens in a new tab) -
hard-cut
Enforce a hard-cut cleanup policy: keep one canonical implementation and delete compatibility, migration, fallback, adapter, coercion, and dual-shape code. Use for pre-release or internal-draft refactors where the goal is one final shape, especially when changing schemas, contracts, persisted state, routing, configuration, feature flags, enum/value sets, or architecture.
skills/engineering/hard-cut/SKILL.md on GitHub (opens in a new tab) -
lean-ci
Right-size CI from measured run data instead of stacking pipeline mechanics. Use when CI is slow, expensive, flaky, or runs too often; when the user asks to clean up, speed up, split, or reduce GitHub Actions, GitLab CI, or other pipelines; when reviewing a CI proposal for over-engineering; and before you yourself add jobs, caches, matrices, path filters, concurrency rules, nightly runs, pre-push…

root-cause-finder
Performs root-cause-first debugging and review by tracing expected behavior to the first unintended side effect before changing contracts, parsing, or types. Use when debugging protocol errors, deserialization failures, null payloads, missing fields, restore or hydration issues, state-ownership bugs, unexpected requests, background mutations, or reviewing junior-created code where the visible fai…
skills/engineering/root-cause-finder/SKILL.md on GitHub (opens in a new tab) -
search-context
Find, clone, inspect, and summarize high-quality GitHub reference repositories for coding agents. Use when a user asks for GitHub reference projects, examples, prior art, inspiration, implementation patterns, or includes "$search-context" in a coding prompt.
skills/engineering/search-context/SKILL.md on GitHub (opens in a new tab) -
gitwhat
Concise git workspace snapshot for the current directory. Use when asked to show current branch, cwd, repo root, whether the current directory is a worktree, local dirty status, or whether other worktrees have uncommitted changes.
skills/git/gitwhat/SKILL.md on GitHub (opens in a new tab) -
go-local-health
Run local Go health checks (tests, coverage, lint) in Go repositories that contain go.mod/go.sum. Use when the user asks to run or interpret local Go test/coverage/lint workflows using tools like lazygotest, gocovsh, tparse, and golangci-lint. Do not use for Rust or non-Go projects.

delegate-fable
Delegate a bounded task from a Codex session to a Fable-powered Cursor Agent in the same Herdr workspace, then wait for and collect the result. Use when Codex should bring in Fable for an independent read-only review or make Fable the sole writer for an implementation while Codex pauses and reviews afterward. Trigger for requests such as "ask Fable", "have Fable review this", "let Fable implement…

delegate-grok
Delegate a bounded task from a Codex session to Grok 4.6 with xhigh reasoning in the same Herdr workspace, then wait for and collect the result. Use when Codex should ask Grok for a strong independent opinion, read-only review, architecture or debugging analysis, second opinion, or explicitly authorized implementation. Trigger for requests such as "ask Grok", "have Grok review this", "get Grok 4.…

delegate-sol
Delegate a bounded task from a Codex session to GPT-5.6 Sol in the same Herdr workspace, then wait for and collect the result. In review mode, require Sol to use parallel GPT-5.6 Terra subagents with medium reasoning for read-only context gathering before Sol makes the final judgment. Use for requests such as "ask Sol", "have Sol review this", "get Sol's opinion", "use Sol with Terra context gath…

homebrew-publish
Publish CLIs/TUIs to Homebrew via a personal tap. Use when asked to create or manage a Homebrew tap repo, generate or update formulae, compute sha256, test installs, or ship new releases for Go, Rust, Node/TypeScript, Python, or prebuilt binaries.
skills/release/homebrew-publish/SKILL.md on GitHub (opens in a new tab) -
package-security-check
Run a reusable JavaScript supply-chain security baseline with pnpm-first hardening, release-age gating, lifecycle-script controls, exotic dependency checks, CI install checks, and optional incident IOC profiles.
skills/security/package-security-check/SKILL.md on GitHub (opens in a new tab) -
secleak-check
Run or install repo security leak checks with BetterLeaks and Trivy. Use when asked to scan for leaked secrets, vulnerable dependencies, misconfigurations, add secret-leak guardrails, add BetterLeaks, add forbidden-path hooks, or run secleak-check before release.
skills/security/secleak-check/SKILL.md on GitHub (opens in a new tab) -
shellck
Run shellcheck on shell scripts after editing scripts or when debugging shell errors. Use for linting scripts in a repo (especially scripts/), catching issues like set -u with unset vars, bad subshell usage, or quoting mistakes.
skills/shell/shellck/SKILL.md on GitHub (opens in a new tab) -
app-spec-packager
Use this skill when the user wants to turn an application, product, startup idea, SaaS, mobile app, web app, API, AI product, or internal tool into a production-ready Markdown specification package for coding agents. Creates PRD/product spec, UX flows, design system brief, technical architecture, ADRs, AI/safety/privacy specs, API/data model, client/backend implementation specs, QA acceptance tes…

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.
