AI Developer Tools

Stele

Stele provides shared memory for AI coding agents, recording decisions, tasks, and lessons to maintain context across tools and sessions.

What is Stele?

Stele is a hosted shared ledger that AI coding agents read and write automatically, preserving project decisions, tasks, and risks so agents stay informed across sessions and tool switches.

  • One living memory: decisions and lessons shared across agents
  • Task coordination: atomic claim of tasks to prevent duplicate work
  • Cross-tool continuity: works with Claude Code, Cursor, Codex, and more
  • Seven breakable boxes covering OWASP Agentic Top-10 vulnerabilities
  • Three guided simulations for cascading failures, human-agent trust, and rogue agents
  • Network-isolated Docker containers for safe execution
  • Code-to-runtime reasoning across cloud, Git, and Kubernetes
  • Action-gate enforces read-only policy on every API call
  • Sandboxed JavaScript execution for concurrent research
  • Append-only, SHA-256-addressed event history through Jaybase

  • Unified RBAC for ledger, notes, snapshots, and audit reads
Pros
  • Seamless context preservation across different AI coding tools
  • Automatic memory maintenance without manual note-taking
  • Covers full OWASP Agentic Top-10 in a realistic manner
  • Docker isolation prevents accidental damage
  • Read-only by construction prevents accidental writes
  • Evidence-backed verification cross-checks every finding
  • Opinionated and secure accounting CLI with immutable audit trail
  • Designed for AI agent integration with JSON output
Cons
  • Currently invite-only, limiting immediate access
  • Requires adoption of Stele CLI and integration into workflow
  • Requires Docker and technical setup
  • Not for production use; only for lab environments
  • Requires an LLM API key, incurring token costs
  • Limited to read-only operations, cannot remediate
  • Pre-1.0, limited feature set

How to use Stele?

  1. 1Install the CLI: curl -fsSL https://app.stele-ai.dev/install.sh | bash
  2. 2Sign in with your invite email: stele account login
  3. 3Inside your agent (e.g., Claude Code), run /stele:start
  4. 4Continue working; the agent now reads and writes the shared record on every prompt.

Stele Key Features

  • One living memory: decisions and lessons shared across agents
  • Task coordination: atomic claim of tasks to prevent duplicate work
  • Cross-tool continuity: works with Claude Code, Cursor, Codex, and more
  • Self-maintaining graph: stale entries flagged, resolved risks retired
  • Provenance: trace decisions back to tasks, documents, and authors
  • Built-in assistant: ask your project questions using live graph context
  • Privacy: data per project, never shared or used for training
  • Onboarding from code: seeds record from existing repo and docs

Stele Use Cases

  • Maintain project context when switching between different AI coding agents
  • Prevent repeated mistakes by surfacing past decisions and risks
  • Enable team collaboration with shared task queues and handoffs
  • Onboard new contributors (human or AI) with full project memory
