WARP v0.0.3 Release Notes

We are excited to announce the release of WARP v0.0.3. This is a major update that transitions WARP from a basic declarative format to a full-fledged agent engineering platform.

This release introduces a robust Plugin Ecosystem, native Model Context Protocol (MCP) integration, fine-grained Security & Tool Policies, hierarchical Subagents Delegation, and a highly advanced Context-Aware Templating Engine.

🚀 Key Highlights

1. Plugin Ecosystem & Package Management

WARP now supports modular packaging and distribution of your agents, skills, commands, and tools.

  • CLI Package Installer: Use the new warp get command to fetch, configure, and install plugins directly from remote repositories.
  • Interactive Configuration: Powered by huh, the CLI prompts you to select exactly which resources to import.
  • Integrity Lockfile (warp.lock): Computes cryptographic checksums of the plugin tree to guarantee workspace supply-chain security.
  • Post-Install Setup Hooks: Supports lifecycle execution hooks (hooks.postInstall) to automatically download assets or compile plugin binaries upon installation.
  • Developer DX (Live Linking): Specifying a relative or absolute local directory as the plugin source bypasses the global cache and enables real-time hot-reloading during development.

2. Model Context Protocol (MCP) Integration

Native integration of the Model Context Protocol allows agents to dynamically interact with external development servers.

  • New Kind: MCP Resource: Declare MCP server configurations using a simple schema.
  • SSE & Stdio Transports: Connect to servers via shell execution (stdio) or HTTP streams (SSE) with support for custom environment variables.
  • Resource Filters: Use policies.tools, policies.prompts, and policies.resources with include/exclude glob lists to filter what the MCP server exposes to agents.
  • Annotations & Safety Profiles: Assign safety labels (like isDangerous or isOpenWorld) to all exposed tools, with key overrides for individual tools.

3. Fine-Grained Security & Tool Policies

Administrators and users can now enforce strict permission boundaries on tool execution.

  • Agent & Workspace Policies: Restrict tool usage at the workspace level (WORKSPACE.md) or override them per-agent (spec.policies).
  • Dangerous Tool Prevention: Setting allowDangerous: false blocks execution of any tool annotated as dangerous.
  • Open-World Access Limits: Restrict tool executions that make uncontrolled network requests or touch the internet.
  • Inheritance & Merging: Child agents automatically inherit, combine, and resolve parent policies during agent resolution.

4. Hierarchical Subagents Delegation

Agents can now collaborate and spawn subagents under clean control flow structures.

  • Delegation Reference Lists: List allowable subagents (spec.subagents) that an agent is permitted to delegate tasks to.
  • Trigger Filtering: Use spec.triggers to define what architectural components (e.g. human, agent, system) are allowed to invoke a particular agent.
  • Wildcard Imports: Support for wildcards (*) to import all commands, skills, or subagents.

5. Rich Model Provider Configurations

LLM Provider specifications have been expanded to capture modern production capabilities and cost tracking.

  • Custom HTTP Headers: Configure custom authentication or tracking headers for all outgoing API requests.
  • Pricing Matrices: Track token usage costs (cost), cache read/write discounts, and conditional pricing tiers based on context window size.
  • Thinking Token Settings: Define sampling bounds and strategy controls (like toggle, effort, budget) for reasoning-based models.
  • Modality Support: Declare accepted input and output modalities (e.g., text, images, video) per-model.

🛠️ Developer Experience & Tooling

Advanced Context-Aware Templating

The templating engine now injects highly structured hierarchical view objects into your instructions.

  • Workspace & Project Directives: Access workspace roots, project directories, and local rules files (AGENT.md).
  • Shorthand Arguments Mappings: Commands map user args to hints automatically (e.g. $ticket maps to the first argument if configured).
  • Self-Aware Metadata: Agents and skills can inspect their own metadata (e.g. {{.Agent.Name}}, {{.Skill.Dir}}).

New Formatting Tooling

  • Format API: Serialize parsed WARP structures back into standard WARP Markdown.
  • Resilient Directory Loader: The filesystem loader now skips files lacking YAML front-matter (like READMEs) inside .agents/ rather than throwing errors.
  • Reflected JSON Schema: Dynamically updates schema/warp.json based on Go struct reflection for VS Code validation and autocompletion.
