From 3dced3a6309be352ac44513332d0584e467b17e5 Mon Sep 17 00:00:00 2001 From: nidheesh-p Date: Fri, 19 Jun 2026 14:19:32 -0700 Subject: [PATCH] feat(cli): add suite runner for scenario + trace directories (#85) Add an `agent-harness suite` subcommand that runs a directory of scenarios against trace files and emits one aggregate summary plus optional per-scenario result JSON. Single-scenario `run` is unchanged. - Map each scenario to `/.json` by id. - Constrain scenario ids to a filename-safe charset and add a path containment check so a trace lookup can never escape `--trace-dir`. - Detect duplicate scenario ids; record per-scenario errors (missing trace, malformed trace, invalid scenario, duplicate id) without aborting the suite. - Fail an empty match / missing trace dir rather than passing vacuously. - Emit per-status counts and provenance (trace path, severity, category) in the summary, validated against schemas/suite_result.schema.json. - `--exit-on-fail` gates on any fail/error, composing with `run`.
