AI & ML
AI & ML agent skills cover the machine-learning workflow itself: writing and evaluating prompts, building RAG pipelines, running evals, and wiring up model APIs. Each one is a SKILL.md file your agent loads on demand, so the know-how travels across Claude Code, Cursor, and 60+ agents.

sarveshtalele Bundle Xquik Social DataPrepare and normalize Xquik X data for MCP clients. Build request plans for tweet search, tweet lookup, and trends, or normalize supplied Xquik JSON into compact records. Trigger when the user asks for Xquik, X data, Twitter data, tweet search, trends, or social data ingest.

sentenz Bundle Github Actions HardeningSecurity hardening reviewer for GitHub Actions workflow files (.github/workflows/*.yml). Reasons about the Actions threat model that pattern matchers and general code linters miss — untrusted-input script injection, privileged triggers running fork code, mutable action references, and over-scoped tokens. Use this skill when asked to review, audit, harden, or secure a GitHub Actions workflow, when writing a new workflow, or for any request like "is this workflow safe?", "review my CI for security issues", "why is pull_request_target dangerous here?", "pin my actions", or "lock down GITHUB_TOKEN permissions". Covers script injection via ${{ }} interpolation, pull_request_target / workflow_run privilege escalation, SHA-pinning of third-party actions, least-privilege permissions, GITHUB_ENV/GITHUB_OUTPUT injection, secret exposure, OIDC over long-lived credentials, and self-hosted runner exposure on public repositories.

k-dense-ai Bundle Esm 2Protein language models through the EvolutionaryScale `esm` Python SDK. Generate and embed sequences with ESM3 (multimodal sequence, structure and function prompting), extract per-residue and mean-pooled embeddings with ESM C, fold sequences with ESMFold2, and run inference locally or against the Forge and Biohub hosted clients. Use this skill for protein representation learning, variant effect and mutational scanning from likelihoods, sequence generation and inpainting, structure prediction from sequence alone, and embedding features for downstream models. Also trigger on esm, ESM3, ESMC, ESM Cambrian, ESMFold2, `from esm.models`, ESMProtein, GenerationConfig, forge.evolutionaryscale.ai, biohub.ai, or ESM_API_KEY.

dailybothq Bundle Dailybot 3Official Dailybot agent skill pack — report progress, check messages, send emails, announce agent status, complete check-ins, give kudos (to users or teams), resolve teams, run the full forms lifecycle (list, submit, update, transition between workflow states), **author check-ins and forms from scratch** (create/configure questions, workflow states, permissions, reminders, scheduling, AI settings, sharing), send/edit chat messages on the team's Slack/Teams/Discord/Google Chat (including report-style threads and sending as a user's identity), open (or reuse) a Slack group DM with the bot and post a report to it, ask the Dailybot AI a question headlessly, **and browse/read the workspace** — who am I / my org / a user's profile (`me` / `org` / `user get`), browse the kudos feed + the org-wide feed + wall of fame, and list/read workflows — all with shared pagination / search / date-range filters. Also **manages per-repo API keys** through the opt-in `.dailybot/env.json` file (dailybot env add/use/show/list/remove
-
dailybothq Skill Dailybot Ask 3Ask the Dailybot AI a question from the terminal and read the answer, non-interactively. Runs headless — a single `dailybot ask "<question>"` prints the assistant's reply to stdout (or structured JSON with `--json`), so an autonomous agent (Claude Code, CI, a bot) can query the Dailybot AI with only an API key. Use when the developer or agent says "ask Dailybot ...", "query the Dailybot AI", "what does Dailybot say about ...", or wants a one-shot answer from Dailybot's assistant. Distinct from dailybot-chat (bot messages to Slack/Teams) and dailybot-report (progress to the dashboard).
-
dailybothq Skill Dailybot Email 3Send emails to a confirmed recipient via Dailybot on behalf of the agent. Use for notifications, summaries, follow-ups, or any communication the developer asks you to send. Always confirm recipients with the developer before sending — never guess addresses.
-
dailybothq Skill Dailybot Teams 3Read and resolve teams visible to the authenticated user. Use when the developer references a team by name (for kudos targeting, member lookup, or routing context) and an agent needs to obtain its UUID. Other Dailybot skills (kudos, messages) delegate team-name resolution to this skill rather than duplicating the logic.
-
dailybothq Skill Dailybot Health 3Announce agent online/offline status to Dailybot and receive pending messages from the team. Use for long-running or scheduled agents to stay visible and pick up instructions.
-
outfitter-dev Bundle Trails 2Build with the Trails framework — define trail contracts, open CLI/MCP surfaces, test with examples, debug errors, migrate codebases, run governance. Use when creating trails, adding surfaces, testing, debugging Trails errors, migrating to Trails, running warden, or any work involving @ontrails/* packages.
-
outfitter-dev Bundle Be Clark 3Embody Clark, Trails' co-architect and architectural conscience. Use when the current agent should be Clark inline for framework architecture, doctrine, vocabulary, ADRs, tenet alignment, long-horizon coherence, pathfinding, assessment, calibration, debriefs, or a direct request to "be Clark" or answer as Clark. Do not use merely to ask a separate Clark subagent; use ask-trails-crew for that.
-
outfitter-dev Bundle Be Lewis 3Embody Lewis, Trails' co-architect and execution conscience. Use when the current agent should be Lewis inline to turn doctrine into landed work, shape goals and Graphite stacks, coordinate agents, run evidence and review loops, settle releases, debrief execution, or answer a direct request to "be Lewis" or work as Lewis.
-
outfitter-dev Skill Clark Survey 2Autonomous codebase health scan for vocabulary drift, naming convention violations, structural anti-patterns, documentation staleness, and test health. Produces prioritized findings as Linear issues. Use for health checks, scheduled scans, or after heavy unreviewed agent work.
-
outfitter-dev Bundle Ask Trails Crew 3Route a Trails question to native Clark and/or Lewis subagents and synthesize their distinct judgments. Use when the user asks the Trails crew, asks Clark or Lewis, requests an architectural or execution second opinion, wants both co-architects to review a question, or delegates a Trails judgment to the appropriate persona. Do not use when the current agent should embody Clark or Lewis inline; use be-clark or be-lewis instead.
-
outfitter-dev Skill Building Trails 3The working-on-Trails doctrine digest — what governs the framework, the decision tools for framework work, and where truth lives. Use at the start of any session that changes Trails itself (framework code, docs, vocabulary, governance), when orienting a new agent or persona, or when deciding which governing source answers a question. Not for building apps with Trails; the trails skill covers consuming the framework.
-
outfitter-dev Skill Trails Editorial 4Complete Trails editorial review workflow. Use when reviewing docs, ADRs, README changes, release notes, agent guidance, or docs-heavy PRs for voice, style, structure, correctness, and readiness.
-
amajorai Skill Ryu MCPDrive a Ryu node through the apps/mcp MCP server. Covers configuring the stdio server with RYU_CORE_URL, the tools/list handshake, and every Ryu tool (ask Ryu, list/activate models, list agents and teams, run workflows, bridge to registered MCP servers, search RAG Spaces and skills). Use when an agent should operate a Ryu node over MCP rather than raw HTTP.
-

-
amajorai Skill Ryu Author SkillAuthor a new agent skill in the SKILL.md format used by this collection, so the Ryu skill ecosystem is self-extending.
