Design Direction

Verified Command Mesh

CodexTerminal 2031 assumes terminals become orchestration surfaces for humans and agents. The aesthetic is high-density and keyboard-first: low-latency legibility, explicit provenance, and safety states that are always visible before execution.

Intent First Every command shows purpose, scope, and expected side effects.

Proof Over Flair Confidence includes evidence and calibration, not opaque scoring.

Safe Delegation Agent work is sandboxed by default with visible permission boundaries.

01 Required

Color Palette

Colors are stateful. Accent hues map directly to execution intent, risk, and trust boundaries.

--void-0#060A12 · Base canvas

--plate#18263A · Elevated surfaces

--signal#39FFB6 · Safe execution + success

--focus#56A7FF · Human selection + links

--warn#FFB24F · Review required

--alert#FF5F78 · Blocked/error states

02 Required

Typography

Display stays technical, body stays readable, and mono owns all command-bearing UI.

Display / Chakra Petch

Orchestrate, Verify, Execute

Used for section headlines and shell identity where high recognition matters.

Body / IBM Plex Sans

Explain model behavior, summarize outputs, and document rationale in plain language without losing density.

Mono / JetBrains Mono

$ codex run --goal "patch login retry"
agent.planner -> tasks:3
agent.reviewer -> risk:medium

03 Required

Spacing Scale

Compact rhythm optimized for dense telemetry while keeping read paths clear.

--space-1 / 6px

--space-2 / 10px

--space-3 / 14px

--space-4 / 20px

--space-5 / 28px

--space-6 / 40px

04 Required

Buttons

Actions encode safety level: execute, request review, or stop before side effects.

05 Required

Forms

Every prompt defines scope and permission policy before dispatching work to agents.

Goal Prompt

Execution Scope

Constraints

Approval Policy Auto-run low risk actions Require approval before write commands

Safety Flags Snapshot before modification Enable rollback checkpoints

06 Required

Cards and Panels

Panel system is purpose-specific: intent, provenance, and post-run proof are separated.

Intent Panel

Clarifies objective and expected user-facing outcome before any tooling runs.

intent://refactor/auth/session-timeout

Provenance Panel

Shows source links, docs age, and command lineage for reproducibility.

proof://source-graph/7-edges

Rollback Panel

Captures snapshots and exact reversal commands when changes are deployed.

rollback://checkpoint/2026-02-23T19:24Z

Terminal Components

Command stream blends human and agent events with explicit state and confidence context.

Agent Panels

Agents expose role, utilization, and trust scope so operators can route work intentionally.

Confidence and Calibration

Confidence is paired with evidence and recency; this avoids false certainty and improves operator trust.

Patch Recommendation

Confidence: 0.82 calibrated Evidence: 7 corroborating refs Staleness: docs <= 21 days

Infra Migration Plan

Confidence: 0.64 exploratory Evidence: 3 partial refs Staleness: mixed recency

Release Rollback Path

Confidence: 0.93 verified Evidence: runbook + dry-run pass Staleness: validated today

11 Optional

Alerts and Notifications

Alerts are concise and actionable, always tied to a command or policy event.

Source Updated New security advisory indexed. Recommendation confidence increased from 0.76 to 0.82.

Checkpoint Saved Rollback checkpoint ckpt-17f2 created before migration edits.

Approval Needed Agent requested elevated network permissions for dependency audit.

Policy Block Destructive command rejected outside approved sandbox scope.
