Coding Agent Control Plane

Standardize how agents work. See what works. Review what they build.

The control plane for coding agents across your engineering team.

Manage and synchronize your agent harness, see which configurations produce better outcomes, and make every agent-built pull request understandable.

One immutable Harness Pack version across the whole system
  1. 01

    Define the agent harness

  2. 02

    Synchronize it across the team

  3. 03

    Agents work with that configuration

  4. 04

    Collect runtime telemetry

  5. 05

    Connect runs to commits and pull requests

  6. 06

    Make the pull request understandable

  7. 07

    Observe review and delivery outcomes

  8. 08

    Improve the harness

The evidence chain

  1. Harness Pack v17
  2. Billing team
  3. Claude Code session 811
  4. Commits a81f2c and b72de1
  5. Pull request #842
  6. One decision changed after review
  7. Harness Pack v18

Focused v1 connects GitHub, Claude Code, and Codex. Runtime comparisons show observed associations with visible sample sizes and coverage; they do not claim causation or score engineer productivity.

One closed loop

The harness, the runtime, and the pull request should not be separate systems.

The same configuration version flows from approval and team assignment into the agent session, the exact commits Fullbeam observes during that session, the resulting pull request, and the review outcome. That evidence feeds the next Harness Pack instead of disappearing into disconnected tools.

Three pillars. One control loop.

  1. 01

    Harness Registry and Distribution

    Version, approve, publish, assign, synchronize, detect drift, roll out, and roll back one canonical Harness Pack compiled for Claude Code and Codex.

  2. 02

    Runtime Intelligence

    Connect the available configuration to actual capability use, failures, verification, commits, and pull requests. Compare observed outcomes with the denominator, sample size, and coverage visible.

  3. 03

    Agent-Aware PR Review

    Combine the goal, plan, material decisions, failed approaches, verification, commits, and final diff into a clear PR Story — then reopen only changed or uncertain work after a revision.

Focused v1: GitHub, Claude Code, and Codex

  • GitHub App
  • Claude CodeRequires agent connection
  • CodexRequires agent connection

GitHub remains the source of truth for repositories, commits, pull requests, and review outcomes. Fullbeam compiles the canonical harness for Claude Code and Codex, then keeps missing or partial runtime evidence explicit.

Outcome comparisons are observational. Every comparison should expose the sample size, denominator, and telemetry coverage; none should be read as causal proof or an engineer productivity score.

Synthetic walkthrough, two revisions

See what a second push actually costs you.

This is a deterministic synthetic sample of an agent pushing after review started. It demonstrates the shipping interaction and continuity rules; it is not evidence from a live customer repository or a live model call.
