- research-audience-score-segment-qagooseworks-ai/goose-skillsStep of the research-audience playbook: scores and tiers list rows, groups them into segments with an angle each, runs the pre-handover checks and writes the list files. Run research-audience instead; not for direct use.TestingNo warnings★ 1.3K↓ —
- verify-cli-runreticlehq/reticleProve that a command-line tool actually did what it said, instead of trusting its exit code and its output. Snapshots the filesystem before and after, names the expected consequence in advance, and returns one of four verdicts with what could not be seen. Use after running a build, a migration, a scaffolder, a formatter, a codegen step, or an AI coding CLI; when a command printed success and you are about to report "done"; when you are about to write "exit code 0, so it worked"; or when a tool claims it edited files. Needs nothing installed.EngineeringNo warnings★ 1.3K↓ —
- oma-pdfNewfirst-fluke/oh-my-agentExtract PDF text, headings, tables, and images into Markdown using opendataloader-pdf. Use for PDF parsing, not PDF layout creation.DocumentsNo warnings★ 1.4K↓ —
- shiphashgraph-online/awesome-codex-pluginsShip phase. Runs isolated integration test in a fresh worktree, creates a PR with full spec + audit report in the body, watches CI, and auto-fixes failures.TestingNo warnings★ 1.5K↓ —
- testing-livekit-agentsfcakyon/claude-codex-settingsWrites turn-level tests for a LiveKit agent in the user's normal test suite: pytest (Python) or Vitest (Node.js). Use when the user asks to "write tests for my agent", "add a test for this tool", "test the handoff", "pin this bug", "why does my agent test fail", or after building or changing agent behavior that needs regression coverage. Covers the SDK's test session harness, assertions on messages, tool calls and handoffs, LLM judging of a reply against an intent, mocking tools, multi-turn tests, and judging whole conversations with the built-in judges. For interactive poking use debugging-livekit-agents. For grading whole conversations at scale use running-livekit-simulations.TestingNo warnings★ 1.2K↓ —Also in 1 other repo
- improve-search-visibility-store-listing-auditgooseworks-ai/goose-skillsAudits an app's App Store and Google Play listing against three competitors (title, subtitle, description opening, first screenshots and captions, rating, review themes) and writes a field-by-field rewrite with character counts, or a launch-day listing before release. Use alone when you already have the app's store links and signed-off product facts; otherwise run improve-search-visibility.WritingNo warnings★ 1.3K↓ —
- oma-securityfirst-fluke/oh-my-agentScan application source, agent skills, and MCP components; run penetration tests against scoped web test deployments, validate findings, and configure scan gates. Use oma-qa for broad quality reviews and domain skills for remediation.SecurityNo warnings★ 1.4K↓ —
- sponsor-researchhashgraph-online/awesome-codex-pluginsSponsor and ad-read research on podcasts and YouTube: who sponsors a show, or which shows a brand sponsors, how often, since when. Uses arcmira.ScienceNo warnings★ 1.5K↓ —
- oma-scholarfirst-fluke/oh-my-agentSearch academic literature and generate, validate, or compare Knows paper sidecars. Use for claim/evidence analysis and literature synthesis.ScienceNo warnings★ 1.4K↓ —
- session-searchhoangsonww/Claude-Code-Agent-MonitorFind Claude Code sessions tracked by the Agent Monitor by project (cwd), model, status, or date, then rank the matches by cost or recency. Pulls the session list and the distinct cwd / facet values so filters use real values rather than guesses. Use when locating a session — "find my EstateWise sessions", "which Opus runs errored this week", "most expensive sessions in /repo".EngineeringNo warnings★ 1.1K↓ —
- jlcpcbhashgraph-online/awesome-codex-pluginsJLCPCB PCB fabrication and assembly — BOM/CPL generation, basic vs extended parts, assembly constraints, design rules, ordering workflow. Use with KiCad for JLCPCB manufacturing. Use this skill when the user mentions JLCPCB, wants to order PCBs or assembled boards, needs prototype bare PCBs and stencils, wants to know JLCPCB design rules and capabilities, or is asking about PCB manufacturing costs or turnaround times. For gerber/CPL export, stencil ordering, and BOM management, see the `bom` skill.DesignNo warnings★ 1.5K↓ —
- oma-skill-creationfirst-fluke/oh-my-agentCreate or revise OMA skills and their references. Use for skill routing, execution contracts, conditional loading, and authoring validation.OtherNo warnings★ 1.4K↓ —
- servershashgraph-online/awesome-codex-pluginsGive a Homie studio game lasting servers - named communities with their own rooms and rules - humans-only, hybrid (seats reserved for AI companions), beginner (new players, AI guides, kids-safe) - plus agent passes, the AI skill dial, the party's level vote, and AI guides that talk (a game vocabulary; Cloudflare's Clef decision model on the studio's Workers AI by default, Llama or the owner's key instead, Clef on the person's own computer under dev, or the owner's own Claude in a seat). Use when someone asks for servers, realms or shards, human-only play, AI party members or companions, guides or helpers for new players or kids, guides that answer "help me with this quest", "fill empty spots with AI", letting Claude play as a guide, which model the guides think with, testing an agents.json, free local AI guides, or how strong the bots should be.TestingNo warnings★ 1.5K↓ —

- inithashgraph-online/awesome-codex-pluginsFirst-time Archcore setup. Wires the host (MCP config, hooks, CLAUDE.md/AGENTS.md managed block), measures the authored context the repo already holds, then composes a first-day seed — stack rule, run guide, data-model, integrations, config, entry points, public surface, a linked architecture overview, and specs for the top hotspot modules — shown in ONE preview and created on a single confirm. Modes, named as the first word: init import converts the repo's authored context — CLAUDE.md, AGENTS.md, .cursor/rules and other agent instructions, ADR and RFC folders, contributor docs, internal pages of a published docs site, recoverable git history — into native typed documents with no import marks, staged by a plan when the volume is large; init refresh adds facts that appeared since, or drills into one domain with init refresh <domain>. Use on a fresh clone, empty `.archcore/`, 'set up archcore', 'migrate our CLAUDE.md to archcore', 'import our docs and ADRs', or to wire host configs.

- company-watchhashgraph-online/awesome-codex-pluginsWatches a company or topic on podcasts and YouTube: what was said lately (shows, counts, momentum, quotes), then an Arcmira monitor to keep following it.OtherNo warnings★ 1.5K↓ —

- dreamhashgraph-online/awesome-codex-pluginsDeep creative exploration engine. Competing perspectives, stress-tested by a 4-persona council, scored by integrity. The approach that survives attack wins — not the one that sounds best.OtherNo warnings★ 1.5K↓ —
- create-prhashgraph-online/awesome-codex-pluginsCreate a GitHub pull request from the current branch. Use when the user says 'create a pr', 'open pr', 'push and open a pr', 'create pull request', or wants to open a PR from their branch.EngineeringNo warnings★ 1.5K↓ —
- email-lifecycle-send-checkgooseworks-ai/goose-skillsChecks a drafted email flow or broadcast before it is loaded: flow logic and exits, overlaps, offer depth and codes, stock, claims, consent and legal footer, SMS rules, rendering, voice and AI-copy tells, and the goal metric. Returns a pass / fixed / open-question table. Use alone when you already have the finished draft and the brand's product and policy facts; otherwise run email-lifecycle.ProductivityNo warnings★ 1.3K↓ —

- simplifyfcakyon/claude-codex-settingsThis skill should be used when the user asks to "simplify", "clean up the diff", "run simplify", "simplify the changes", "review changed code for cleanup", explicitly invokes "/simplify", or asks to "commit without simplify", "skip simplify for this commit", or "commit this but skip simplify". Reviews changed code across reuse, simplification, efficiency, and altitude, or grants an explicit one-commit bypass. Not for correctness bugs.EngineeringNo warnings★ 1.2K↓ —
