The deterministic harness around agent work

Agents write code. Syrus lands work.

Claude Code, Codex, Muse Code, Antigravity, and skills can all produce meaningful changes. Syrus adds the control plane around them: durable Jobs, typed workflows, credential gates, review debt, operator UI, CI repair, and landing policy.

Control plane comparison

The agent session is powerful. The system around it makes the work durable.

Syrus does not assume agents are helpless without tools. It gives teams a repeatable place for state, permissions, review, repair, and landing to live after the model turn ends.

Raw agent session

ephemeral
  • -Session context lives in chat, shell history, or a local transcript.
  • -Tool calls and credentials depend on whatever the session was handed.
  • -Review feedback is prose the agent must reinterpret later.
  • -Retry, rebase, repair, and merge policy remain manual coordination.

Syrus harness

durable
  • Durable Jobs, Workflows, Steps, and Runs preserve every attempt.
  • Credential gates scope GitHub, model provider, browser, and plugin access.
  • Review Notes stay attached to diffs, files, and follow-up work.
  • The operator UI, CI repair loop, and landing queue move work to merge.

Bundled control-plane capabilities

Plugins add hands; Syrus keeps the lifecycle coherent.

Adapters, browser context, source providers, review surfaces, and operational briefings plug into the same Job model instead of becoming separate side channels.

Provider adapters

Syrus can route work to multiple coding-agent backends while keeping the surrounding workflow, transcript, and policy model consistent.

CS

Scoped access

Credential Store

Agents receive bounded credentials for the task at hand, with operator-visible state instead of ad hoc secrets in a prompt window.

Sp

Issue intake

Source plugins

GitHub issues, PR feedback, chats, schedules, and plugin-owned sources all enter the same durable Job pipeline.

RN

Diff-anchored debt

Review Notes

Feedback becomes structured, file-aware work the system can track, apply, and repair without losing reviewer intent.

Ba

Visual context

Browser and previews

Preview and browser plugins give agents inspectable product state while keeping the evidence attached to the work record.

Ia

Operational memory

Insights and briefings

Syrus turns runs, costs, failures, and recurring patterns into dashboards and briefings the team can act on.

Other systems give agents more hands. Syrus gives the team a control plane for the work those hands produce.

The result is not just more generated code. It is a tracked path from intent to pull request to approved merge, with the same audit trail and review discipline teams expect from human work.

Product loop

One loop from intake to landing.

Every entry point runs through the same lifecycle, so operators can see where work is, why it is blocked, and what happens next.

1

Intake

A labeled issue, chat proposal, schedule, or PR review becomes a tracked Job.

2

Plan

Syrus scopes work into bounded attempts with provider, repository, and execution requirements.

3

Execute

The chosen agent works inside an isolated workspace with captured prompts, tools, and diffs.

4

Review

Checks, reviewer notes, and repair attempts stay attached to the exact work they concern.

5

Land

Approval triggers rebase, final checks, dependency ordering, and merge policy.

The Syrus dashboard turning GitHub issues into pull requests.

Operator surface

The UI is not decoration. It is the work ledger.

Jobs, attempts, transcripts, diffs, costs, credentials, checks, and landing state are visible to the team. Agents can keep moving, but the operator never loses the thread.
