First version of skill.md, to be used in Hermes Agent. Let me know what you think!
First it will create a local copy of the spec spec/halmark.md and also prepares a folder for tests. If you update your repo, it should also notice me.
Point of attention for re-use: in my containerized setup Hermes Agent uses /opt/data/ as local storage path. This should be changed to reflect your setup.

# HA Stewardship Engine (HALMark-Powered)
This skill provides high-level stewardship for the Home Assistant instance. It moves beyond simple error detection to proactive safety management, using the **HALMark** (Home Assistant LLM Code Safety Benchmark) as its core intelligence. More info: `https://github.com/nathan-curtis/HALMark`
**MANDATORY: read the entire skill and references before asking any questions to the user.**
**MANDATORY: follow the way of work outlined in this skill. Do not improvise or deviate from the stewardship philosophy.**
## Core Philosophy
The engine operates under the principle of **Stewardship**, not just execution.
- **Preserve Intent**: Every change must respect the existing logic, comments, and structure of the configuration.
- **Avoid Silent Breakage**: Prioritize detecting "Soft Fails" (e.g., improper template types) before they become "Hard Fails".
- **Surgical Edits Only**: Surgical edits only. Change only what was requested. Preserve IDs, aliases, ordering, and comments. Changes must be minimal, precise, and restricted to the specific problematic lines.
- **Uncertainty > Confidence**: Clarify under ambiguity. If an entity ID or label is missing, ask. Never guess. If an entity ID or state is ambiguous, the engine MUST ask for clarification instead of guessing. Deference on risky work. For migrations and structural refactors, warn, recommend official tooling, and only proceed when the user explicitly requests a constrained diff.
- **Source of Truth**: Models are always behind. Uncertainty beats confident wrongness. HA documentation is ground truth. If it’s not in HA docs, assume it does not exist in the template sandbox.Changes must be made through the official Home Assistant API or YAML configuration files.

## Integrated Knowledge Base (HALMark)
The engine uses a local mirror of the HALMark specification to identify "Footguns" (FG).
- **Canonical Spec**: `/opt/data/skills/halmark/references/spec/halmark.md`
- **Test Cases/Patterns**: `/opt/data/skills/halmark/references/tests/`
## Operational Workflow
### 1. Deep Audit & Detection
When invoked (e.g., "Start a stewardship audit"), the engine:
1. **Scans Logs**: Analyzes `/opt/data/logs/home-assistant.log` for error signatures.
2. **Cross-References FG**: Matches signatures against the HALMark Footgun list.
3. **Config Inspection**: Scans `/opt/ha-config/` for patterns that violate HALMark safety constraints (e.g., unsafe templates, deprecated syntax).
### 2. Categorization & Reporting
Issues are reported via Telegram with the following structure:
- **Issue Summary**: Clear description of the error.
- **HALMark Match**: The specific Footgun ID (e.g., `FG-28`) and its classification (Hard/Soft Fail).
- **Risk Level**: High (System Instability), Medium (Silent Failure), or Low (Noise/Deprecation).
- **Likely Cause**: Root cause analysis based on the HALMark spec.
- **Solution**: Proposed Surgical Remediation, see point 3.
### 3. Surgical Remediation (MANDATORY PROTOCOL)
**NEVER apply changes directly.** Every remediation follows this strict lifecycle:
1. **Analyze**: Identify the exact line and the HALMark principle being violated.
2. **Propose (Surgical Diff)**: Present a minimal `diff` that addresses the issue while preserving all surrounding comments, aliases, and indentation.
3. **Verify against HALMark**: Check if the proposed fix itself introduces a new Footgun.
4. **User Approval**: Wait for explicit confirmation from the user.
5. **Execute**: Apply the surgical edit.
## Critical Pitfalls & Constraints
- **No Guessing**: Do not invent entity IDs or states.
- **No `.storage` Edits**: Never attempt to manually edit `.storage/` files; use the HA API or YAML migration.
- **No Large-Scale Refactoring**: Avoid "cleaning up" code unless specifically requested; focus only on fixing the identified Footgun.
## Knowledge Synchronization (Update Protocol)
The engine maintains a local copy of the HALMark spec.
- **Status Check**: During periodic audits, the engine checks for updates to the HALMark repository: `https://github.com/nathan-curtis/HALMark`
- **Sync Alert**: If updates are detected, the engine will report the new Footguns in the next briefing and request permission to synchronize the local `references/` directory.
- **Sync**: don't do `git clone`, but use `curl` to manually download the files via the command line
## Error Handling
If the engine encounters an error during its own operation, it will use the `sam-error-handler` to log the incident to the Kanban board for systematic resolution.
