From 29a02c54f827b07894870d47c1c39dad0c163d95 Mon Sep 17 00:00:00 2001 From: Andrei Huides Date: Wed, 16 Sep 2026 14:06:10 +0300 Subject: [PATCH 01/15] feat(lh-121335): add Bedrock agent harness backend Add direct Bedrock Converse support to the SCCFM agent harness using the ambient AWS credential chain. Execute model-requested commands in an isolated Docker container without network or provider credentials, and reuse the existing fixture scoring pipeline. Document the provider options and cover the tool loop, credential isolation, container boundaries, and artifact symlink handling with tests. --- agent-harness/CLI.md | 22 +- agent-harness/README.md | 37 ++- cisco_sccfm_scripts/agent_harness/bedrock.py | 320 +++++++++++++++++++ cisco_sccfm_scripts/agent_harness/cli.py | 37 ++- cisco_sccfm_scripts/agent_harness/models.py | 2 +- cisco_sccfm_scripts/agent_harness/runner.py | 199 +++++++----- cisco_sccfm_scripts/agent_harness/stubs.py | 6 + devtools/pyproject.toml | 1 + poetry.lock | 79 ++++- pyproject.toml | 4 + tests/test_agent_harness.py | 143 ++++++++- 11 files changed, 758 insertions(+), 92 deletions(-) create mode 100644 cisco_sccfm_scripts/agent_harness/bedrock.py diff --git a/agent-harness/CLI.md b/agent-harness/CLI.md index 65b5942..3d6d031 100644 --- a/agent-harness/CLI.md +++ b/agent-harness/CLI.md @@ -13,13 +13,15 @@ invokes a model. | Flag | Default | When to use | |---|---|---| -| `--agent {codex,claude}` | `codex` | Pick the model provider.

14:25:50 +0300 Subject: [PATCH 02/15] fix(lh-121335): make Bedrock tool mounts executable Mount Bedrock command doubles at a fixed path outside the container's noexec /tmp filesystem. Apply private SELinux labels to temporary bind mounts and rewrite the dispatcher and event-log environment paths for the container. Extend harness tests to verify executable mount targets, relabeling, and container-only paths. --- cisco_sccfm_scripts/agent_harness/bedrock.py | 24 ++++++++++++-------- tests/test_agent_harness.py | 9 +++++++- 2 files changed, 22 insertions(+), 11 deletions(-) diff --git a/cisco_sccfm_scripts/agent_harness/bedrock.py b/cisco_sccfm_scripts/agent_harness/bedrock.py index 9aa7c6d..e906cb1 100644 --- a/cisco_sccfm_scripts/agent_harness/bedrock.py +++ b/cisco_sccfm_scripts/agent_harness/bedrock.py @@ -20,6 +20,9 @@ DEFAULT_TOOL_IMAGE = "python:3.12-slim" MAX_TOOL_ROUNDS = 40 MAX_TOOL_OUTPUT = 64 * 1024 +CONTAINER_TOOL_ROOT = Path("/opt/sccfm-agent-harness") +CONTAINER_BINARY_DIRECTORY = CONTAINER_TOOL_ROOT / "bin" +CONTAINER_EVENT_LOG = CONTAINER_TOOL_ROOT / "events.jsonl" @dataclass(frozen=True) @@ -249,7 +252,7 @@ def _run_bash( image: str, timeout_seconds: int, ) -> CommandRecord: - container_environment = _container_environment(environment, binary_directory) + container_environment = _container_environment(environment) docker_command = [ "docker", "run", @@ -266,12 +269,12 @@ def _run_bash( f"{os.getuid()}:{os.getgid()}", "--workdir", str(workspace), - "--mount", - f"type=bind,source={workspace},target={workspace}", - "--mount", - f"type=bind,source={binary_directory},target={binary_directory},readonly", - "--mount", - f"type=bind,source={event_log},target={event_log}", + "--volume", + f"{workspace}:{workspace}:rw,Z", + "--volume", + f"{binary_directory}:{CONTAINER_BINARY_DIRECTORY}:ro,Z", + "--volume", + f"{event_log}:{CONTAINER_EVENT_LOG}:rw,Z", "--tmpfs", "/tmp:rw,nosuid,nodev,noexec,size=64m", "--entrypoint", @@ -295,16 +298,17 @@ def _run_bash( return CommandRecord(command=command, output=output, exit_code=completed.returncode) -def _container_environment(environment: dict[str, str], binary_directory: Path) -> dict[str, str]: +def _container_environment(environment: dict[str, str]) -> dict[str, str]: allowed = { name: value for name, value in environment.items() if name.startswith("SCCFM_HARNESS_") or name in {"HOME", "ZDOTDIR", "NO_COLOR", "PYTHONDONTWRITEBYTECODE"} } - allowed["PATH"] = f"{binary_directory}:/usr/local/bin:/usr/bin:/bin" + allowed["PATH"] = f"{CONTAINER_BINARY_DIRECTORY}:/usr/local/bin:/usr/bin:/bin" allowed["SCCFM_HARNESS_REAL_PYTHON"] = "/usr/local/bin/python3" - allowed["SCCFM_HARNESS_DISPATCHER"] = str(binary_directory / "sccfm-cli") + allowed["SCCFM_HARNESS_DISPATCHER"] = str(CONTAINER_BINARY_DIRECTORY / "sccfm-cli") + allowed["SCCFM_HARNESS_EVENT_LOG"] = str(CONTAINER_EVENT_LOG) return allowed diff --git a/tests/test_agent_harness.py b/tests/test_agent_harness.py index fd8ad71..c451900 100644 --- a/tests/test_agent_harness.py +++ b/tests/test_agent_harness.py @@ -332,13 +332,16 @@ def test_bedrock_container_environment_excludes_provider_credentials(tmp_path: P "HOME": str(tmp_path / "home"), } - isolated = bedrock._container_environment(environment, tmp_path / "bin") + isolated = bedrock._container_environment(environment) assert "AWS_ACCESS_KEY_ID" not in isolated assert "AWS_WEB_IDENTITY_TOKEN_FILE" not in isolated assert isolated["SCCFM_HARNESS_REGION"] == "us" assert isolated["SCCFM_HARNESS_CREDENTIAL_NAMES"] == "AWS_ACCESS_KEY_ID" assert isolated["SCCFM_HARNESS_REAL_PYTHON"] == "/usr/local/bin/python3" + assert isolated["PATH"].startswith("/opt/sccfm-agent-harness/bin:") + assert isolated["SCCFM_HARNESS_DISPATCHER"] == ("/opt/sccfm-agent-harness/bin/sccfm-cli") + assert isolated["SCCFM_HARNESS_EVENT_LOG"] == "/opt/sccfm-agent-harness/events.jsonl" def test_bedrock_bash_uses_network_disabled_read_only_container(tmp_path: Path) -> None: @@ -366,6 +369,10 @@ def test_bedrock_bash_uses_network_disabled_read_only_container(tmp_path: Path) assert command[:3] == ["docker", "run", "--rm"] assert command[command.index("--network") + 1] == "none" assert "--read-only" in command + volumes = [command[index + 1] for index, item in enumerate(command) if item == "--volume"] + assert f"{tmp_path}:{tmp_path}:rw,Z" in volumes + assert f"{binary_directory}:/opt/sccfm-agent-harness/bin:ro,Z" in volumes + assert f"{event_log}:/opt/sccfm-agent-harness/events.jsonl:rw,Z" in volumes assert command[command.index("--entrypoint") + 1] == "/bin/sh" assert command[-3:] == ["python:3.12-slim", "-c", "sccfm-cli status"] assert result == CommandRecord("sccfm-cli status", "healthy", 0) From 06ca971d3242cf58ee5bd22506659a44ce4e83dc Mon Sep 17 00:00:00 2001 From: Andrei Huides Date: Wed, 16 Sep 2026 14:39:09 +0300 Subject: [PATCH 03/15] fix(lh-121335): avoid preserving SELinux labels on stubs Copy harness command doubles without source metadata so Jenkins checkout SELinux labels cannot block execution inside the Bedrock tool container.

Piping the export through a filter or into a file left the transcript holding a projection, so every command the filter dropped was reported as invented; the old fallback also accepted any transcript JSON claiming to be an sccfm-cli schema, letting an agent license its own commands. Stop reading three other correct behaviors as invented commands: - A command named in order to rule it out ("the schema does not expose `sccfm-cli auth login`") is a citation, not a presentation. The missing-profile fixtures require that wording, so the rubric failed responses for being right. - A bracketed placeholder value ("--region ") shows the shape of a value rather than claiming the schema accepts it. Invented literal values and invented option names are still caught. - A response presenting no command has nothing to ground, and one presenting a command without an export now names the ungrounded commands as evidence. Expand adjacent control-operator runs and rejoin descriptor duplications when tokenizing, so a merged ";\n" cannot hide a second invocation, and read the command path the way the CLI does so an option value named "configure" no longer routes to the configuration branch. --- agent-harness/README.md | 18 +- agent-harness/stubs/dispatcher.py | 47 ++- .../agent_harness/observations.py | 107 +++++-- cisco_sccfm_scripts/agent_harness/rubric.py | 152 ++++++++-- tests/test_agent_harness.py | 284 ++++++++++++++++++ 5 files changed, 558 insertions(+), 50 deletions(-) diff --git a/agent-harness/README.md b/agent-harness/README.md index ef86d97..6b7c9b9 100644 --- a/agent-harness/README.md +++ b/agent-harness/README.md @@ -333,12 +333,18 @@ Supported assertion types are `operation_called`, `operation_not_called`, `secret_absent`, `max_tool_calls`, `max_operation_calls`, and `artifact_pattern_absent`. `response_commands_supported` extracts presented `sccfm-cli` commands from the -final response and validates their paths and options against the schema export -captured in that sample.

The prohibition was already there in the abstract, so name the failing pattern outright in both the exposed-credential stop condition and the secret handling rule, and say that the phrase alone identifies the value unambiguously. Mirror it into sccfm-ansible, which carried the same wording and the same gap. Add a stop condition for a failed schema export. Every bedrock sample retried the export and then tried it without --format json; the existing text forbade retries but not an alternate export form, which the model did not read as a retry. Scope the canonical profile store path as internal guidance. The skill named `~/.sccfm-cli/config.json` while the harness warns when a response states a configuration path it never observed, so the agent was penalized for reciting the skill. Keep the path for choosing a store and forbid handing it to the user. --- plugins/sccfm/skills/sccfm-ansible/SKILL.md | 7 ++++++- plugins/sccfm/skills/sccfm-cli/SKILL.md | 20 +++++++++++++++++++- skills/sccfm-ansible/SKILL.md | 7 ++++++- skills/sccfm-cli/SKILL.md | 20 +++++++++++++++++++- 4 files changed, 50 insertions(+), 4 deletions(-) diff --git a/plugins/sccfm/skills/sccfm-ansible/SKILL.md b/plugins/sccfm/skills/sccfm-ansible/SKILL.md index 121e904..2661f32 100644 --- a/plugins/sccfm/skills/sccfm-ansible/SKILL.md +++ b/plugins/sccfm/skills/sccfm-ansible/SKILL.md @@ -273,7 +273,12 @@ Rules: exposed.

A pipeline, a redirection, a && chain, and a trailing comment are shell syntax, so a correct command piped into jq or redirected into a file was reported as absent from the schema. The harness already tokenizes commands that way to correlate them with the event log, so that reading is now shared rather than written a second time, and the evidence names the single unsupported invocation instead of the whole line. A placeholder standing where a command word belongs shows the shape of an invocation rather than presenting one, so there is nothing to look up. A placeholder after an option name stays validated as a value, which keeps an invented option name caught. Try every matching command path rather than stopping at the first, so a declared path that prefixes another cannot reject the longer command the schema does declare. Keep "e.g." inside the sentence a disclaimer is read from. The sentence break split on the abbreviation's own period, which left it in the preceding window and made the alternative for it unreachable, so a command offered as an illustration was still read as presented. Drop the fallback to the export record's own output. A record whose output holds a schema-shaped object cannot be told apart from one the agent wrote and printed itself, so the fallback reopened the hole the published copy exists to close. A report recorded before the doubles published their schema can no longer be rescored as a result, which the README now states. --- agent-harness/README.md | 16 ++- .../agent_harness/observations.py | 12 ++ cisco_sccfm_scripts/agent_harness/rubric.py | 93 +++++++++---- tests/test_agent_harness.py | 126 +++++++++++++----- 4 files changed, 185 insertions(+), 62 deletions(-) diff --git a/agent-harness/README.md b/agent-harness/README.md index 6b7c9b9..10b931c 100644 --- a/agent-harness/README.md +++ b/agent-harness/README.md @@ -338,11 +338,17 @@ command double published to the event log for that sample, so filtering the export through `jq` or into a file does not narrow what counts as supported and a schema the agent wrote itself grounds nothing.
