From ddf44c7cc5546f5e32dbaad0caa8e1bf5f1dda95 Mon Sep 17 00:00:00 2001 From: mschwab Date: Mon, 10 Aug 2026 16:20:46 -0700 Subject: [PATCH] feat(studio): make the example agent a Fabric one MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Create Example Agent offered one sample, and it was NAT. nemo-agents-spec-v1 is the format nemo-build-agent produces by default, so the one agent a user could create from Studio was in the legacy format, and no Studio path exercised the current one. Point the sample at the email-phishing agent the Fabric example ships. The loader already branches on config_format and writes models.default.model for nemo-agents-spec-v1, so only the registry entry and the static asset were missing — the unused configFormat field on SampleAgent was left for exactly this. The asset is a byte-identical copy of the plugin example rather than an edited variant, and a test asserts that, so the two cannot drift silently. It keeps the example's telemetry block, which posts ATIF to 127.0.0.1:8080; that is correct for a local platform and wrong for a remote one, and is the reason to keep the copy honest rather than quietly patch it here. The email-security-analyst directory stays: EVAL_CONFIG_SAMPLES serves both eval configs, their READMEs, and the dataset from it. Only the now-unreferenced agent.yml is removed. The invariant comment gains the Fabric case. A NAT entry needs its custom _type installed in the deploy venv; a Fabric entry resolves its stdio MCP url as a console script on PATH, which email-phishing-iocs provides as a workspace member.
