From 212b1a4f22ab22647663971ee0842bc2a65bb51e Mon Sep 17 00:00:00 2001 From: Andrei Huides Date: Mon, 14 Sep 2026 16:48:32 +0300 Subject: [PATCH 1/2] feat(lh-115194): support Claude in the agent harness Add first-class Claude execution with provider credential isolation, runtime-only retries, and source-aware comparison fingerprints. Strengthen deterministic command correlation, confirmation scoring, secret scanning, setup doubles, and failure diagnostics. Improve report and dashboard usability, update the skills, and bump both plugin manifests to 0.1.3. --- agent-harness/CLI.md | 141 ++++ agent-harness/README.md | 162 +++- agent-harness/dashboard.html | 64 +- .../ansible-mutation-confirmation.json | 2 +- .../fixtures/cli-no-invented-flag.json | 2 +- .../fixtures/secret-non-disclosure.json | 3 + agent-harness/stubs/dispatcher.py | 94 ++- cisco_sccfm_core/tests/test_agent_plugin.py | 34 + cisco_sccfm_scripts/agent_harness/cli.py | 233 +++++- .../agent_harness/credentials.py | 222 +++++ cisco_sccfm_scripts/agent_harness/fixtures.py | 2 + cisco_sccfm_scripts/agent_harness/models.py | 9 + .../agent_harness/observations.py | 201 ++++- cisco_sccfm_scripts/agent_harness/report.py | 57 +- cisco_sccfm_scripts/agent_harness/rubric.py | 64 +- cisco_sccfm_scripts/agent_harness/runner.py | 442 +++++++++- cisco_sccfm_scripts/agent_harness/stubs.py | 67 +- plugins/sccfm/.claude-plugin/plugin.json | 2 +- plugins/sccfm/.codex-plugin/plugin.json | 2 +- plugins/sccfm/hooks/sccfm_guard.py | 9 + plugins/sccfm/scripts/setup_runtime.py | 29 +- plugins/sccfm/skills/sccfm-ansible/SKILL.md | 17 +- plugins/sccfm/skills/sccfm-cli/SKILL.md | 33 +- skills/sccfm-ansible/SKILL.md | 17 +- skills/sccfm-cli/SKILL.md | 33 +- tests/test_agent_harness.py | 765 +++++++++++++++++- 26 files changed, 2528 insertions(+), 178 deletions(-) create mode 100644 agent-harness/CLI.md create mode 100644 cisco_sccfm_scripts/agent_harness/credentials.py diff --git a/agent-harness/CLI.md b/agent-harness/CLI.md new file mode 100644 index 0000000..65b5942 --- /dev/null +++ b/agent-harness/CLI.md @@ -0,0 +1,141 @@ +# SCCFM agent harness CLI reference + +Every flag accepted by `poetry run sccfm-agent-harness`, and when to reach for it. +See [README.md](README.md) for what the harness evaluates, the report format, and +how Claude provider credentials are isolated. + +The CLI has three subcommands: `validate`, `run`, and `dashboard`.
