Powerful Detection, Zero Overhead
A six-stage detection pipeline that identifies skill usage in milliseconds. No agent instrumentation. No prompt modification.
Detection Pipeline
Six strategies ordered by confidence. The pipeline short-circuits on the first match for maximum speed.
Watermark Scan
Regex scan for <!-- skill:name/version --> comments
Frontmatter Hash
SHA-256 of YAML frontmatter block
Content Hash
SHA-256 of normalized full content
Tool Schema
JSON schema fingerprinting of tool definitions
Prefix Hash
SHA-256 of first 500 tokens
Function Signature
Regex pattern matching on function signatures
Telemetry Emitters
Send detection events wherever your infrastructure needs them. Async, fire-and-forget delivery.
JSONL
File-based, zero dependencies. Append-only log format.
SQLite
Embedded database with WAL mode for concurrent reads.
HTTP
Batched delivery with exponential backoff retry.
PostgreSQL
Production-grade storage with TimescaleDB support.
OpenTelemetry
OTLP spans for distributed tracing integration.
Prometheus
Metrics endpoint for monitoring and alerting.
Enterprise Features
Built for production workloads at scale. Security, performance, and multi-tenancy out of the box.
Multi-Registry
Merge multiple fingerprint sources into a unified index.
Multi-Tenant
Per-tenant routing with isolated registries and emitters.
Sampling
Random or deterministic sampling for high-throughput environments.
Signature Verification
Ed25519 signatures to verify registry authenticity.
Hot-Reload
fs.watch + polling for live registry updates without restart.
Registry Caching
LRU cache with SHA-256 keys for fast repeated lookups.
Performance That Disappears
Designed to add negligible latency to your gateway. Detection happens in microseconds to milliseconds.
