Rate limit the export API
Burst traffic from a single tenant can starve the queue. Add per-tenant limits and return 429 with a retry hint.
Ticket to PR
Every ticket in your backlog is a pull request waiting to happen.
Coding agents are fast. Someone still has to drive them.
Cosmos picks up tickets from Jira, Linear, or Slack, plans the change with full codebase context, implements it, and opens a PR that has already been through review. You read the plan and merge the result.

Meet Cosmos
A teammate for every ticket.
Assign an issue to Cosmos the way you would assign it to an engineer. It scopes the work, asks when the ticket is ambiguous, and shows up with a reviewed PR instead of a draft.

Minutes
From ticket assignment to a draft PR
A fleet of experts takes ownership from intake to merge.
Cosmos orchestrates the whole path. Task Intake turns the ticket into a scoped spec, the Planner maps the change against your live codebase, the PR Author implements it, and the review fleet checks the work before a human sees it. Every loop shares memory.
Delegation lifecycleone ticket, end to end
Intake
Task Intake
Picks the ticket up from Jira, Linear, or Slack and gathers linked issues, comments, designs, and prior art.
Plan · Approval
Planner
Scopes the change against the live codebase with the Context Engine and posts a plan back on the ticket.
Human
Reads the plan on the ticket and approves or redirects it in one comment.
Implementation
PR Author
Implements the change, runs the tests, fixes CI and conflicts, and answers review comments until merge.
Review
Review Fleet
Risk, correctness, and judgment passes from the code review experts before a human opens the PR.

Built for delegation
Delegation, not supervision.
Coding assistants make one engineer faster and keep them in the driver’s seat for every step. Cosmos takes the whole ticket, works it in the background, and comes back when something is worth your attention.
Supervision
Built around an open editor
- One task at a time, with you driving
- Context lives in your head and your prompts
- Progress stops when you switch tabs
Delegation
Built around the ticket
- Assign from Jira, Linear, or Slack and move on
- Context comes from the Context Engine
- Tickets run in parallel, in the background
- Returns a reviewed PR, not a diff to babysit
What changes when teams delegate.
Customers that route their ticket queues through Cosmos report the same shape of results: more tickets closed each week, hours from assignment to PR becoming minutes, and engineer time shifting to the calls that need a human. The charts show a representative deployment.
