AI summary
Auto-generated overview of what this skill does and when to reach for it.
Cryptographic, task-scoped authorization for AI agents using short-lived, holder-bound capability tokens called warrants that expire automatically and can't be expanded once issued.
Use this when
- Your agent calls external tools and needs to limit which ones it can use per task
- You want to stop prompt-injected agents from exceeding their intended scope
- You need verifiable, offline authorization checks under 50 microseconds
- You want to delegate authority that only narrows, never expands
- You need signed, auditable proof for every tool call decision
Don't use when
- You only need static role-based access control (RBAC)
- Your security model relies on prompt engineering alone
- You can't bind tokens to cryptographic keys in your runtime
Capabilities
- Issues task-scoped, expiring warrants called 'capability tokens'
- Holder-bound proofs prevent stolen tokens from being reused
- Offline verification in under 50 microseconds with no network calls
- Monotonically attenuating authority—delegated tokens can only shrink scope
- Semantic constraints (e.g., Subpath, UrlSafe, Pattern) that match target system parsing
- Integrates with OpenAI, LangChain, FastAPI, MCP, and other agent frameworks
