[External Plugin]: oddyssey

Review using-system/oddyssey at marketplace/oddyssey, ref v1.12.1 and commit 407c8e2248c12e112098861a9c577027708ba031. Start with eng/external-plugin-quality-gates.mjs and scripts/build-marketplace.sh, then inspect the root plugin.json and Copilot extension layout. Done means the quality gates and install smoke test pass and the submitted plugin structure matches the stated marketplace requirements.

Plugin name

oddyssey

Short description

Observability-Driven Development for coding agents: an OpenTelemetry instrumentation expert, a run-observation agent that measures a service through its telemetry on a local Grafana stack or a remote backend (Grafana, Datadog, Dynatrace, Azure Monitor, CloudWatch), a verification pass that replays a stored run, k6 benchmark authoring, and a committed .odd/ memory that carries the loop across runs.

Additional notes for reviewers

Resubmission of #3089 (closed by the submitter after requires-submitter-fixes): the install smoke test and version match failed there because the manifest only existed under .claude-plugin/plugin.json. Since v1.12.0 the build also emits plugin.json at the plugin root in the Agent Plugins v1.0.0 shape ($schema, name, version, description, author, homepage, repository, license, keywords), next to the Claude Code one.

v1.12.1 addresses the review on this issue: the Copilot components now ship under the com.github.copilot/ extension namespace (agents/, commands/, hooks/hooks.json with ${PLUGIN_ROOT} paths and the hook scripts) and the MCP server in a root mcp.json in the spec's shape, beside the Claude Code layout. Verified with Copilot CLI 1.0.83 (--plugin-dir, debug log): 4 agents, the 7 commands translated into skills, the 9 skills, the hooks and the MCP server all load with no warning.

All gates were replayed on this tag/SHA with eng/external-plugin-quality-gates.mjs before the previous edit; on v1.12.1, vally lint (runLint({rootPath})) passes with 9 skills and the install smoke test (ephemeral marketplace, fresh HOME, Copilot CLI 1.0.83) installs the plugin with plugin.json at the installed root at version 1.12.1. The plugin tree is generated from an APM package on every release (scripts/build-marketplace.sh) and is also installable today through copilot plugin marketplace add using-system/oddyssey.
