The handoff that survives the trip to an AI coding agent
Capture the screen, talk through the issue, publish a URL. The URL is the artifact you hand to a teammate AND to the agent, same content, same format, no translation step.
You spotted a problem. An AI coding agent is going to fix it. Between those two events sits the handoff, and the handoff is where most feedback loses its information. This page is the playbook for closing that gap. It belongs to the feedback for AI coding agents hub.
The handoff problem
Someone spots an issue. A PM walks the staging build before a release. A QA engineer hits a regression on a flow that worked yesterday. A designer notices the spacing on the dev implementation has drifted from the Figma. The next step, increasingly, isn't "file a ticket and wait." It's "ask the agent to fix it."
Between those two events sits the handoff. And most feedback dies there.
It dies because the reviewer reaches for the wrong format. A Slack screenshot strips out the source URL and the dictated nuance. A Jira ticket forces the reviewer to type a paragraph they would have said in ten seconds. A Loom captures everything the reviewer noticed and is unreadable by the agent that has to act on it. Every option is a translation step, and translation steps lose information.
A handoff that doesn't lose information
The CobaltCapture pattern collapses the translation step. You capture the screen while you are looking at the issue. You drag a box around the part that matters. You hit dictate and talk through the problem out loud, the same way you would explain it to a colleague standing next to you. You repeat that for each finding. You hit publish.
What you get is a public URL like cobaltcapture.com/r/abc12345. That URL is the handoff artifact.
The same URL goes to two audiences. You paste it in Slack to your engineering teammate, who reads the findings as a clean markdown document with cropped screenshots inline. You paste it into your AI coding agent's prompt, and the agent follows the URL, ingests the same markdown, and starts work on the same findings the human just read.
One artifact. Two readers. No retranslation between them. The reviewer captured context once, and both downstream audiences got the full record. The artifact is the message, not a derivative of it.
Example: PM-to-Cursor handoff
A PM walks the staging build. They find three issues. They capture, dictate, publish. They drop the URL in the engineering channel:
Staging review for the new checkout flow:
https://cobaltcapture.com/r/k9m2x4pq
Three findings. Submit button overflow on mobile is the blocker
the other two can wait.
The on-call engineer opens the URL, sees the screenshots and the dictated context, and pastes it into Cursor:
The PM walked the checkout staging build and flagged three issues here:
https://cobaltcapture.com/r/k9m2x4pq
Address item 1 first (the submit button overflow). Show me the diff
before moving to items 2 and 3.
Cursor follows the URL, pulls the screenshots into context, reads the dictated commentary, and starts work on the first finding. Same artifact, two readers, zero loss between them.
Why this format survives
Markdown is plain text. Every AI agent on the market reads it natively, with no plugin, no integration, no proprietary viewer. The embedded screenshots have stable public URLs that the agent can fetch on demand. The source URL is stamped on every item, so the agent knows which page each finding refers to without guessing. The dictated commentary captures the "why" and the "where" that a one-line written description always skips. "Only on iOS Safari after the keyboard dismisses" is the kind of detail you say out loud but rarely type.
And because the document is also legible to humans, it survives the chain of forwarding that real handoffs go through. A PM sends it to engineering. Engineering forwards it to the agent. A QA engineer references it in the PR comment. The artifact does not degrade at any step.
Compared to other handoff artifacts
A Loom walkthrough captures everything the reviewer noticed. The agent cannot watch it. The receiving human has to scrub through a video to find the bit that matters. Both audiences are worse off than they would be reading a structured document.
A Linear or Jira ticket is heavy. It forces the reviewer to choose a project, an assignee, and a priority before they can describe the issue, and the on-page context gets lost the moment the ticket lives in a separate tool.
A Slack screenshot is fast but ephemeral. There is no record. Anyone who joins after the message scrolls past is missing the context.
The pattern for a handoff that survives is: (a) readable by both humans and AI agents, with no translation step between them, and (b) accessible at a public URL without authentication, so the artifact can be forwarded freely. CobaltCapture is built around those two constraints. The same constraints show up in the product review use case, where the reviewer and the implementer may be the same person hours apart, or a chain of three people, or a person and an agent.
