## Baseline Core

Baseline Core comes from Baseline Studio, an agent-native studio in New York founded by designer and builder Trent Mitchell. Its central idea is simple: an agent is only as good as the context it can reach, so the studio builds the systems around the model — how context is organized, how rules are documented, and how knowledge surfaces when the agent needs it.

Baseline Core is the flagship of that idea for product teams. It is a product system you can drop into almost any AI tool: 12 skills, 14 frameworks, and 34 reference files covering research, strategy, specifications, design, and planning. It is delivered through a command-line interface and loaded into any AI tool that reads an AGENTS.md file, meaning an assistant can generate product requirements, research summaries, and strategy documents informed by your own methodology and business context rather than generic templates.

Baseline Studio also publishes related open-source projects. The Runtime Classifier encodes creative style as runtime rules across an eight-dimension framework, and the Personal Assistant Agent is a Claude Managed Agent for always-on inbox triage that ingests Gmail, Slack, Granola, and Notion. Baseline Core itself is open source under the MIT license, so teams can read, fork, and extend it, and the studio continues to develop more projects at the intersection of creativity and AI.

**Pricing & Plans:** Baseline Core is free and open source under the MIT license, with no per-seat cost to adopt the skill system itself. Related projects vary: the Personal Assistant Agent, for example, is built on Claude Managed Agents and is described as costing roughly $8–20 per month to run. For bespoke work or the other tools, Baseline Studio invites you to get in touch for pricing.

- **Product methodology system:** Twelve packaged skills plus fourteen frameworks cover research, strategy, specs, design, and planning so your agent has a repeatable product workflow.
- **AGENTS.md delivery:** Install via a CLI and the content loads into any AI tool that reads AGENTS.md, including popular coding assistants and editors.
- **Business context for agents:** Bring your product, market, and customer context so the agent produces specs and documents grounded in your reality.
- **34 reference files:** Thirty-four reference files on research, strategy, specs, and design can be surfaced when the agent needs them.
- **Open source (MIT):** Licensed MIT and published on GitHub so you can inspect, extend, and adapt every part of it.

**Strengths:** Brings real product methodology and business context into AI agents; Open source under MIT and published on GitHub; Portable across any AI tool that reads AGENTS.md; Structured 12 skills / 14 frameworks / 34 reference files covering the full product workflow

**Limitations:** Requires an AI coding tool that reads AGENTS.md (e.g. Claude Code, Cursor) to be useful; Setting up skills and business context takes an initial investment of time; The Personal Assistant Agent requires Anthropic Console / Claude Managed Agents access; Newer entries in the project family are still in development

## Missive

Missive was built around a simple observation: email was designed for individuals, but most businesses run on shared inboxes that several people need to work on together. Missive turns those inboxes into team workspaces. Every email becomes a conversation where colleagues can discuss the reply internally, assign ownership, and see who is handling what. Team inboxes, shared tasks, private notes, and tags replace forwarded messages and side-channel chat apps, keeping context attached to the message it belongs to.

The platform is a full email client as well, supporting Gmail and Google Workspace, Microsoft 365 and Outlook, IMAP, plus SMS and other channels. On top of that sits an automation layer: rules can handle repetitive routing and tagging tasks automatically, and integrations with more than 25 apps such as Stripe and CRMs pull extra context into the inbox. The AI assistant is positioned as a real assistant rather than a generic sidebar, gathering context from connected tools via MCP before drafting a reply.

Missive is popular with small and mid-sized businesses that live in email, including accounting, legal, real estate, logistics, and professional services firms. Customers include teams of 100-200 and above, and the company publishes customer stories, a status page, and a partner program for certified consultants.

**Pricing & Plans:** Missive offers a free trial so teams can invite colleagues and evaluate the product before paying. Paid plans are subscription-based per user, with tiers determined by team size and required features. Exact rates are published on the Missive pricing page.

- **Shared team inboxes:** Let multiple people work the same inbox with clear assignment, internal statuses, and visibility into who is answering what.
- **Internal conversation on emails:** Discuss and prepare replies inside the email thread itself, so context stays attached and nobody is left out of the loop.
- **Tasks and workload visibility:** Turn any email into an assigned task and see what each teammate is working on today, tomorrow, and next week.
- **Automations and rules:** Automate repetitive routing, tagging, and follow-up with rules, rule templates, and workflow automations.
- **AI assistant and integrations:** An AI assistant that gathers context from connected tools via MCP, plus integrations with 25+ apps including Stripe and CRMs.

**Strengths:** Turns shared inboxes into genuinely collaborative workspaces with internal chat; Combines email, tasks, automations, and integrations in one client; AI assistant pulls context from connected tools rather than acting as a generic sidebar; Strong fit for small and mid-sized teams that run on email

**Limitations:** Pricing is per-user and scales up with larger teams; The depth of features can be more than a very small team needs
