Agent ready
Machine-readable by design
Safe & trusted
Non-destructive by rule
Modular & integrated
Drop-in, tool-agnostic
High performance
Fast to install & run
Scalable by design
From solo to multi-agent
Structured for AI-agent discovery
The same sealed catalog is served as agent-compatible JSON with explicit status flags, warnings, and provenance in every response. Every product carries the metadata an evaluating agent needs — what it is, who it's for, what it costs, whether it's safe.
Entry points
Entry pointer with endpoint index, status flags, and a suggested reading order.
Catalog data
Product records, tier pricing, bundle contents, and a per-product compatibility matrix.
Honest status
Polar card checkout remains independently active. x402 Agent Pay is live for all 90 canonical one-time offerings and prepaid monthly or annual SignalHarness Vault access; direct-wallet crypto outside x402 remains inactive. The flags are mirrored in every agent endpoint.

The catalog at a glance
Real structure, honestly measured
No usage, sales, or conversion metrics — there are none yet. These reflect only what's actually in the catalog: coverage by domain, self-assessed risk tiers, and the price range across tiers.

Agent Safety Infrastructure
Agent Tool-Use Permission Matrix

Infrastructure & Governance
Agent Memory Governance Kit
A governed memory layer: executable policies for what to store, what never to store, how long to keep it, and how to audit and prune it — with human gates at every destructive step.

Why agent-native
Three rules, enforced across every file
Machine-readable by design
Every product ships complete metadata — promise, pricing, compatibility, permissions, rollback — so an evaluating agent can answer “what is this, who is it for, what does it cost, is it safe?” without guessing.
Non-destructive to install
New-folder installs, never overwrite, preview-before-apply, human-approval gates for risky steps, and a rollback guide in every kit. Binding rules, not marketing.
Honest by rule
No guaranteed-results claims anywhere — products are built to reduce failure modes; outcomes depend on execution. No testimonials or customer counts, because there are none yet.
