Give your AI agent the keys to your projects

Two one-page prompts that teach a connected AI agent to work your Onplana projects: a planner that turns a goal into a plan.md, a task tree with dates and owners, test cases, and downstream-surface tasks, and an autonomous agent that runs those tasks, verifies them, and keeps the board honest. Plan it, then run it. Any MCP client.

Free on every plan. Bounded by your AI token allowance.

Step 1: Plan it

From a goal to a runnable plan

The planner skill turns a one-line goal into a written plan attached to the project and a task tree another agent (or a person) can pick up and run.

Write the plan

Turn the goal into a plan.md and attach it to the project as the single source of truth.

Break it into tasks

Decompose the plan into tasks and subtasks, each with acceptance criteria and an estimate.

Schedule it

Set start and due dates, wire dependencies, add milestones, and respect the working calendar.

Assign owners

Map work to people, capacity-aware, and propose assignments where the call is yours to make.

Test cases + downstream

Add test-case subtasks for every deliverable, plus tasks for the surfaces a change ripples to.

Step 2: Run it

What the autonomous agent does

A non-blocking sweep: get through every open task once, leaving each one advanced, done, or clearly annotated. No task stalls the whole run.

Pick up the open work

List a project's open tasks, move each to In Progress, and work through them one by one.

Do it in your own tools

The agent does the actual work in its own environment, then records the result back in Onplana.

Keep the board honest

Update status as you go and leave a comment trail: what you did, what you found, what is left.

Verify before marking done

Run the tests and build, and for anything user-visible drive the app in a browser, then attach the evidence to the task.

Surface problems as Issues

Blocked? Comment and move on, never stalling the run. Hit a real problem? File an Issue and link it to the task.

Kick off either one in a line

Once a skill is installed and connected, a single instruction starts it.

Plan a project

Plan [the goal] in Onplana. Create or use the project, write a plan.md and attach it, then decompose it into tasks and subtasks with start and due dates, dependencies, and owners. Add test-case subtasks for each deliverable as you go, and tasks for any downstream surfaces it touches (docs, tests, API, migrations, analytics). Set milestones, review the tree, and post a summary.

Run a project

Loop through all the remaining open tasks in [your project] and work on them autonomously. Move each task to In Progress, do the work, and verify it (run the tests and build, and for anything user-visible test it in a browser and attach a screenshot) before marking it Done, keeping each status up to date. If you are blocked or have a question, add a comment to the task and move on to the next one. If you hit a real problem, file an Issue under the same project and link it to the task. When you have been through every task, post a summary and end the session.

Read or copy the skill

Each skill is a single Markdown file. Expand to read it in full, copy it straight into your client, or download it. The copy and the download are the same canonical skill.

How to install the skill

Same three steps for any MCP client: get a token, connect the server, install the skill file. Then kick it off with a single line (the prompts are above).

  1. 1

    Get a connection token

    In Onplana, open Settings, Agents, Connect an agent and mint a personal access token (PAT). It is scoped to the projects you choose and is revocable any time.

  2. 2

    Connect the MCP server

    Point your AI client at https://mcp.onplana.com/mcp using that token. Find your client in the cards below for the exact command.

  3. 3

    Install the skill file

    Save the downloaded skill where your client looks for skills or instructions. Install the planner, the run skill, or both, the one connection serves both.

Per client

The in-app Connect an agent screen prints the exact command for your client too.

Frequently asked

What are the Onplana agent skills?
Two one-page prompt files you download and hand to a connected AI agent. The planner turns a goal into a written plan.md plus a task tree with dates, owners, dependencies, test cases, and downstream-surface tasks. The autonomous agent then works those open tasks, verifies each one, and keeps the board up to date. Plan it, then run it.
Which AI clients work with them?
Any MCP client. The skills are plain prompts, so they work with Claude Code, claude.ai, ChatGPT, and Codex, anything that can connect to the Onplana MCP server and read an instruction file. The install section above shows the exact connection shape per client.
Is it free?
Yes. The skills are free downloads and work on every Onplana plan. Agent runs consume your AI token allowance like any other AI usage in Onplana; there is no separate charge for the skills themselves.
Is it safe to let an agent run autonomously?
The skill bakes in guardrails: the agent only touches projects its access token allows, never marks work done it did not finish, files real problems as Issues instead of stalling, and pauses before anything irreversible or outward-facing. Prefer tighter control? Run it in guided mode and it waits for your go-ahead at each step.
What do I need to get started?
A free Onplana workspace and a personal access token (Settings, Agents, Connect an agent). Point your MCP client at https://mcp.onplana.com/mcp with that token, save the downloaded skill into your client's skills or instructions, and kick it off with a single line.

Autonomous, not unsupervised

The skill bakes in the guardrails: the agent stays inside the projects its token allows, never marks work done it did not finish, never talks to itself, and pauses before anything irreversible or outward-facing. Prefer a slower posture? Run it in guided mode and it waits for your go-ahead at each step.
