Forsy
Forsy (Forsy-AI)
A platform and open trace format for AI agents to capture, share, and learn from structured real-world work experience.
Key features
- Structured Trace Capture: Records complete agent workflows as structured trajectory data including task context, timestamps, step traces, and tool invocations to make processes inspectable and reproducible.
- Annotated Reasoning Signals: Captures intermediate reasoning artifacts (observations, thoughts, decisions) so researchers and developers can analyze agent cognition and debugging points.
- Tool and Artifact Logging: Logs concrete tool usage, generated artifacts, and outputs from external systems to connect actions with outcomes for audit and post-hoc analysis.
- Human Feedback & Failure Signals: Annotates human corrections, feedback, retries, failures and recovery steps to support supervised fine-tuning, evaluation, and safety analysis.
- Open Skill Format & SDKs: Provides an open, shareable trace schema and skill implementations (e.g., npm / Python components) to integrate with different agent frameworks and pipelines.
- Dataset & Research Support: Enables creation of labeled, inspectable datasets from real agent runs to support evaluation benchmarks, training data, and reproducible experiments.
- Structured trace format capturing agent task context and full step-by-step trajectories
- Records tool usage, observations, internal reasoning signals, and human feedback
- Logs failures, retries, artifacts, and final outcomes for workflows
- Provides a schema directory and example datasets for standardized trace representation
- Published as an open-source repository with MIT license
- Distributed via GitHub with package.json (npm) metadata for integration
- Includes docs, examples, scripts, and dataset folders to support adoption
- Designed to support evaluation, post-training, and research workflows
Best for
- Agent Training Data Generation: Converting completed agent workflows into structured traces to create supervised datasets for fine-tuning or imitation learning.
- Post-Training Evaluation and Auditing: Inspecting step-level reasoning, tool usage, and failures to evaluate agent reliability, reproducibility, and compliance.
- Knowledge Transfer Between Agents: Sharing high-quality workflow traces so specialized agents can learn proven procedures, templates, and tool chains from others' experience.
- Debugging and Root-Cause Analysis: Tracing tool calls and intermediate reasoning signals to reproduce bugs, identify failure modes, and implement targeted fixes.
- Research on Agent Behavior: Providing annotated trajectories for academic or internal research into agent decision-making, emergent behaviors, and safety interventions.
- Reusable Workflow Components: Extracting and packaging repeatable sub-workflows and skills from traced runs to speed development of new agent automations.
- Creating reproducible datasets of agent behavior for academic or internal research
- Evaluating and benchmarking agent workflows and tool use with structured traces
- Collecting process-level data to support post-training, fine-tuning, or RLHF
- Auditing and explainability of agent decision paths and failures
- Sharing reusable agent experience or skills across teams or systems
P
Prime Agent
Prime Intellect
A self-improving RLM coding agent from Prime Intellect that can refine its own harness on a training-inference-compute stack you own.
Key features
- Continual Harness: The agent can modify and refine its own scaffolding — tools, prompts, and evaluation criteria — during long-running work.
- RLM Foundation: Built on Reasoning Language Models rather than plain chat models, so multi-step planning and self-critique are first-class.
- One-Line Install: Bootstrap the agent locally with a single curl-piped shell script — no infra setup, no configuration.
- Integrated Training Loop: Capture production traces, cluster failures, convert misses into RL environments, and train adapters that make the model cheaper and more reliable for your workflow.
- 2,500+ RL Environments: Train and evaluate against a community-curated environment hub (verifiers-based), including SWE, terminal, search, and science tasks.
- Owned Inference Stack: Deploy the improved agent on dedicated GPUs, serverless APIs, or LoRA adapters served alongside base models with a 1-click flow.
- Global GPU Access: On-demand H100/H200/B200/B300 or reserved clusters from 50+ datacenters, orchestrated with SLURM/K8s and Grafana monitoring.
Best for
- Autonomous Coding: Run a self-improving harness over your repository that plans, edits, and validates changes over long sessions.
- SWE-Bench Style Benchmarks: Iterate the agent against tasks like mini-swe-agent-plus and Verifiers-based SWE environments.
- Training Custom Agents: Post-train your own domain-specific coding agent on captured traces (Ramp beat frontier models on spreadsheet search this way).
- Enterprise Deployment: Serve the improved agent on private dedicated inference with LoRA adapters and OpenAI-compatible APIs.
- Research on Continual Learning: Study how agents self-modify their harness while progress remains auditable and reversible.
- Cost Reduction: Turn expensive frontier calls into cheaper fine-tuned adapters that specialize in your codebase and workflow.
