A multi-agent coding setup should not force a person to act as the status dashboard for a collection of separate chats, terminal sessions and IDE windows. The proposed fix is to give the lead agent responsibility for coordinating the overall goal, keep execution safeguards in software, and make the human decision point persistent and easy to return to.
This is a proposed architecture, not a claim that these connections are already implemented.
Four roles, with distinct responsibilities
- Opus, the lead agent: Understands the approved plan, chooses priorities, spots drift and coordinates research or coding work. It is an active coordinator, not just a task recipient.
- Astra, the research agent: Investigates specific questions and returns evidence, including relevant counterarguments, to the lead agent.
- Pi with Sonnet, the coding agent: Works on a bounded task in a fresh context, then submits a candidate change for review.
- GPT-6-Sol, the independent reviewer: Checks both whether the code meets its acceptance criteria and whether the process’s gates are proportionate to the risk. Those judgments should be recorded separately: a failed test is not the same thing as a conclusion that a rule should change.
A programmatic execution layer sits beneath those roles. It checks whether a proposed action falls within the current authorization, manages execution and verification, and preserves evidence. It should not decide which product goal matters most. Jev may assist with bounded judgments about scope, risk or failure categories, but it does not create permission to act. When a choice cannot be settled within the approved scope, the ana-architect analysis process can prepare options and a decision brief for a person; it need not be a fifth always-on agent.
Make approval apply to a version and scope—not forever
Routine prioritization, ordinary fixes and the next task can proceed automatically when they remain within an approved scope. A new decision is needed when the proposal materially changes: for example, when requirements evolve, a major redesign is proposed, a key ADR decision would be replaced, or acceptance criteria or important gates would change.
A progress update, better issue locator or saved execution receipt does not by itself amount to a plan change. That distinction avoids interrupting people for routine bookkeeping while preserving a clear checkpoint for consequential decisions.
A decision brief should say what is blocked, what the existing gate protects, what would happen if it were retained, relaxed or replaced, and which option is recommended and why. It should also state exactly what work approval would authorize. Comparative scoring should not be presented as objective if there are no measurements or explicit scoring rules behind it.
A person may approve a change to a gate or acceptance rule. But the record should preserve the original failure and identify the replacement rule; changing the contract is not evidence that the earlier check passed.
Treat the interface as part of the control system
A plan stored in a file is not enough if the user still has to piece together the overall status from Roo chats, Pi sessions and tmux output. A single reconnectable interface should provide three views:
- Overall progress: the approved goal, progress by Epic or Task, active roles, blockers and the latest checkpoint.
- Changes: the file tree, candidate diff, relevant verification results and independent review.
- Decisions: pending requests, with actions to approve, reject or ask for more analysis.
When a person’s input is needed, the system should save the decision request first and pause the affected work. If the IDE is closed, there is no window to receive a live response; on reconnect, the interface should restore the current project status and pending decision without requiring the person to reconstruct it from old conversations.
Reconnecting to the interface should not restart a task, and opening a decision request should not require restoring an old model chat. An approval must refer to a specific proposal version and scope, so an earlier approval cannot silently apply to a changed plan. People should remain free to use an IDE of their choice; if human edits conflict with agent work, the system should detect the conflict, preserve the human’s changes and pause affected execution rather than assume it can control the person’s workflow.
Put Cline back on the shortlist
Cline’s official documentation describes an interactive TUI for conversational work, plan review and action approval, as well as CLI support for headless workflows.10
7 It also documents Agent Teams and Subagents, but those features are not equivalent capabilities of the VS Code and JetBrains extensions.

That makes Cline CLI/TUI a reasonable priority candidate for the lead agent’s coordination and the human-facing control surface. Pi could remain the Sonnet execution endpoint, Jev could be connected through a verified interface, and Sol could remain an independent reviewer. Existing programmatic assets could become the execution layer rather than being discarded or treated as the overall coordinator.
This is a division of responsibilities—not a proposal to run two separate lead-agent loops. Nor does shared project lineage prove that a migration would be small. Methodology documents may be reusable, but custom Roo modes, tool permissions, execution receipts, Pi’s lifecycle and the pending-decision workflow each need to be mapped. Cline’s documentation also distinguishes CLI and desktop features from its IDE extensions, so a simple extension swap should not be assumed to deliver the same coordination capabilities.5

A small integration test is a better next step than either a full rewrite or ruling Cline out in advance.
Choose a TUI by how well it reconnects the whole workflow
Cline already offers a terminal interface, so a terminal-based workflow need not begin with an unofficial fork.10 OpenCode also documents a TUI and a programmatic CLI, but that does not establish that it is the particular Cline fork someone may have in mind.
2
The specific fork has not been identified here, and there is not enough information to conclude that its file tree, diff view or approval recovery meet the requirements. A useful evaluation should ask whether the interface can summarize the whole pipeline rather than just one agent’s conversation, preserve pending human decisions across reconnects, and show Pi’s work and the independent review against the same candidate version.
A polished TUI can reduce the effort of staying oriented. But if it only displays its own engine’s session, it will not solve the fragmentation problem.
Update the plan around the revised boundary
The plan and its ADR should make five changes explicit:
- Replace “the Python controller coordinates everything” with “the Opus agent coordinates goals; software enforces authorization and execution constraints.”
- Require a new human decision for each material plan evolution, while allowing automatic progress inside an approved scope.
- Add Sol’s review of gate proportionality and the path from ana-architect analysis to a human decision.
- Make the reconnectable TUI, persistent decision requests and recovery view core deliverables—not later dashboard polish.
- Reassess Cline as a control-surface candidate while preserving useful Pi, verification, budget, checkpoint and incident-response assets where they fit.
A strong acceptance test would close the local interface while work continues in the background; have Sol challenge a gate; save an analysis brief and wait for a person; then reconnect to find the overall status and pending decision in one place. After the person approves a specific change, the system should continue under that revised version of the plan.
The central design is Opus for goal coordination, Sol for independent checks, human decisions at material plan changes, and one reconnectable interface—not a program acting as the sole strategic coordinator, an IDE treated as read-only, or a single approval that authorizes an indefinite run.
