Backplanes Spotlight
Backplanes
Automatic session reports for Claude Code and Codex agents showing files touched, commands run, external tools reached, scope drift, and review items.
Key features
- Automatic Session Reports: Produces per-session reports for Claude Code and Codex that summarize actions, touched files, commands executed, and external calls to third-party tools.
- File-Level Traceability: Identifies and lists files created, modified, or deleted during an agent session so reviewers can inspect exact changes and their context.
- Command and Action Logs: Captures commands and high-level actions executed by agents (shell commands, IDE operations, tool invocations) to recreate and audit workflows.
- External Tool Interaction Tracking: Records which external services or tools the agent reached (APIs, CLIs, cloud services) to surface potential data exfiltration or dependency use.
- Scope Drift Detection: Highlights when an agent’s actions diverge from the original task or intent, flagging areas that need human attention or rollback.
- Review Prioritization: Flags risky or unusual operations and ranks items deserving human review to reduce time spent on low-value checks.
- Session Timeline Visualization: Provides chronological timelines of agent activity to help investigators and engineers follow execution flow and reconstruct decisions.
- Organizational Oversight: Aggregates agent activity across teams and vendors to enable multi-tenant monitoring, accountability, and governance.
- Automatic session report generation for agent runs
- Explicit support for Claude Code and Codex sessions
- Tracks files touched/modified during a session
- Records commands executed by the agent
- Tracks external tools and APIs reached during execution
- Detects scope drift across the session
- Highlights actions and artifacts that deserve manual review
- Free at launch
Best for
- Security & Incident Review: Investigating a suspicious agent session to see which files were accessed, which external APIs were called, and whether sensitive data may have been exposed.
- Vendor and Contractor Oversight: Monitoring agent-driven work performed by third-party vendors to ensure actions stay within scope and comply with internal policies.
- Code-Generation QA: Reviewing outputs from Claude Code or Codex sessions to validate generated code changes, commands executed, and identify potential regressions.
- Compliance and Audit Trails: Providing auditable records of automated agent activity for regulatory or internal compliance purposes, including timeline and action logs.
- Scope Management: Detecting and correcting scope drift when an agent starts performing tasks outside the intended objective, preventing unintended changes.
- Postmortem & Debugging: Reconstructing agent workflows after a failure to determine root cause by reviewing chronological actions, file edits, and external calls.
- Change Control and Approval: Using prioritized review items to gate merges or deployments that were initiated or modified by agent sessions.
- Developer audit of autonomous code-generation or modification runs
- Security and compliance review of agent interactions with external tools and systems
- QA and debugging to reproduce and understand agent-driven changes
- Review prioritization by surfacing risky or out-of-scope actions
- Post-run reporting for teams integrating agent workflows into CI/CD
Rezonant
Rezonant
Converts product vision into engineering-ready tasks, orchestrated agents, and shipped code to streamline product-to-engineering delivery.
Key features
- Intent Capture: Converts high-level product descriptions into structured, machine-readable specifications to preserve product intent throughout delivery.
- Task Generation: Automatically generates engineering-ready tasks from product requirements, including acceptance criteria and context for implementation.
- Agent Orchestration: Coordinates autonomous or semi-autonomous agents to act on tasks (e.g., prototype, implement, test, or validate) to accelerate execution.
- Code Linking: Associates tasks and agent activity with shipped code, enabling traceability from product decision to implementation artifacts.
- Traceability and Audit: Maintains a continuous lineage of product intent → tasks → agents → code to support review, auditing, and change rationale.
- Collaboration Workspace: Provides a shared environment for product managers and engineers to review, refine, and approve generated tasks and agent outputs.
- Capture product intent and specifications as first-class inputs
- Automatic generation of engineering-ready tasks from product intent
- Orchestration and management of agents to execute subtasks and workflows
