Tessl

Tessl Agent is Tessl’s agentic experience for creating and maintaining improvement loops in software factories. It mines pull requests and issues for repeated tasks that can be automated, and provides maintenance workflows such as scheduled scans for architecture quality, code duplication, test quality, and security vulnerabilities. Tessl describes its loops as workflows that read a team’s standard, perform the associated work, and improve as they run; the platform includes automated code review, security scanning, documentation maintenance, test-and-fix, model and agent evaluation, and cost benchmarking.

Agent Skills is an open-source collection of engineering workflows for AI coding agents, developed by Addy Osmani. It packages senior-engineering practices into skills covering the development lifecycle: defining specifications, planning, incremental implementation, testing and debugging, constraints, code review, web-performance auditing, code simplification, and shipping. Slash commands such as /spec, /plan, /build, /test, /review, and /ship activate the corresponding workflows, while skills can also activate automatically based on the work being performed. The /build workflow can generate a plan and implement its tasks in an approved pass, while retaining test-driven verification, individual commits, and pauses for failures or risky steps. It can be installed with the skills CLI or integrated into supported coding agents including Claude Code, Cursor, Codex, Copilot, and Cline.

Tadata is an AI employee for Slack that handles research and repetitive sales and go-to-market operations work. It can prepare call briefings, research prospects and companies, draft outreach and follow-up emails, fill CRM fields, monitor relevant LinkedIn activity, and suggest recurring automations. It connects to tools such as HubSpot, Attio, Notion, Linear, GitHub, Google Sheets, Gmail, and Google Calendar, as well as external web sources and MCP or API integrations. Tadata runs pre-built agents or builds an agent from a described process. It observes repeated work, learns team preferences, and requests approval before automating tasks or sending messages; connected-tool access is scoped to the user's authorization. The service is presented as model-agnostic, with portable automations, preferences, exceptions, and agent behaviors that can be exported and versioned.

Agent Skills is a curated skill registry and npm-based CLI for extending AI coding agents such as Claude Code, Cursor, Copilot, and Antigravity with packaged instructions, templates, and reference files. The CLI fetches a catalog, lets users search and select skills, caches downloads locally, and installs them to selected agents by copying or symlinking them at global or project scope; it also supports updating, removing, auditing, and managing cached skills. The repository describes the catalog as an open-source, human-curated library with CI static analysis, content hashing, lockfiles, path isolation, symlink guards, sanitization, audit logging, and Snyk Agent Scan checks. It also includes an MCP server that exposes progressive-disclosure tools for listing, searching, reading, and fetching skill files. The CLI source is MIT-licensed; maintainer-authored skills are generally CC BY 4.0, while third-party skills retain their own licenses.

Distilly is an AI agent skill-generation tool by titanwings that turns messages, documents, interviews, and other supplied sources into source-grounded Person Profiles. It models observable experience, decision patterns, expression, and ways of working, rather than claiming to clone a person, and supports colleague, relationship, and celebrity profile families. Each generated profile is packaged as an installable Agent Skill for supported hosts. Its workflow includes family-specific source collection and analysis, a six-dimension research pipeline for celebrity profiles, incremental file analysis and merging, conversational corrections written to a correction layer, and automatic version archiving with rollback to earlier versions. Supported source types include Lark, DingTalk, Slack, public X posts, WeChat exports, PDFs, images, email, Markdown, and pasted text, with source-specific setup requirements. The project documents native local Skill discovery for Claude Code, Hermes, OpenClaw, Codex, DeepSeek Harness, Pi, Grok Build, and OpenCode. It is distributed from its GitHub repository under the MIT License and is described as a demo version.
