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.

1

Watermark Scan

Regex scan for <!-- skill:name/version --> comments

1 confidencemicroseconds
2

Frontmatter Hash

SHA-256 of YAML frontmatter block

0.9 confidencesub-ms
3

Content Hash

SHA-256 of normalized full content

0.7 confidence<1ms
4

Tool Schema

JSON schema fingerprinting of tool definitions

0.6 confidence<1ms
5

Prefix Hash

SHA-256 of first 500 tokens

0.5 confidence<1ms
6

Function Signature

Regex pattern matching on function signatures

0.4 confidence<1ms

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.
