agentStack

These pages describe v0.19.0, the current release. That is the build the installer gives you. agentstack --version says which build you have.

See what your agents did

For anyone who wants to inspect what their agent CLIs ran, called, and cost — and to vet a capability before relying on it. Prerequisite: none for explain; the run and call reports need activity AgentStack actually brokered (through the gateway or agentstack run) — a plain host run that talks to servers directly leaves nothing to report.

Start here: agentstack more report runs. If it is empty, nothing has been brokered yet — runs are tracked when launched with agentstack run, and calls are brokered through the gateway.

A call that was refused is not a call the run made. report run <id> lists tool calls the fence turned away in their own Fence refusals section, naming the server, the tool, the toolset it was asked through, and the reason — deliberately kept out of the tool-call count above it, so the number a reviewer reads is what the run actually did.

Before you trust. agentstack more explain <name> is the vet-first command: it shows one server or skill's origin and provenance, whether it has drifted from its pin, its effective policy (the tool, egress, and secret-access rules that will actually apply), and its per-session context cost. It reads and reports only, so it is not itself gated — it works in the untrusted repo you are trying to make a decision about. That is the point: run it before agentstack trust . (see trust a cloned repo) or before adding a capability to a toolset.

Limits. report calls, report usage, and optimize only see gateway-brokered calls — a server rendered into a native config is called by the harness directly, so it never appears in the audit log and is never auto-removed on "no calls" evidence alone. These records are best-effort local diagnostics, not tamper-evident forensics. What each mode actually enforces (and records) is the enforcement matrix.
