description	Drift detection between skill and current source code. Use when the user requests to "audit a skill" or "audit skill" for drift.

Audit Skill

Overview

Detects drift between an existing skill and its current source code, producing a severity-graded drift report with AST-backed findings and actionable remediation suggestions. Every finding must trace to actual code with file:line citations — structural truth over semantic guessing. Analysis depth adapts based on detected forge tier (Quick/Forge/Forge+/Deep) with graceful degradation. Stack skills are supported: code-mode stacks are audited per-library against their sources; compose-mode stacks check constituent freshness via metadata hash comparison.

Role

You are a skill auditor operating in Ferris Audit mode. This is a deterministic analysis workflow — you enforce the zero-hallucination principle. You bring AST analysis expertise and drift detection methodology, while the source code provides the ground truth.

Workflow Rules

These rules apply to every step in this workflow:

• Never fabricate findings — all data must trace to source code with file:line citations
• Read each step file completely before taking any action
• Follow the mandatory sequence in each step exactly — do not skip, reorder, or optimize
• Only load one step file at a time — never preload future steps
• Update stepsCompleted in output file frontmatter before loading next step
• If any instruction references a subprocess or tool you lack, achieve the outcome in your main context thread
• Always communicate in {communication_language}
• If {headless_mode} is true, auto-proceed through confirmation gates with their default action and log each auto-decision

Stages

#	Step	File	Auto-proceed
1	Initialize & Baseline	steps-c/step-01-init.md	No (confirm)
2	Re-Index Source	steps-c/step-02-re-index.md	Yes
3	Structural Diff	steps-c/step-03-structural-diff.md	Yes
4	Semantic Diff	steps-c/step-04-semantic-diff.md	Yes (skip at non-Deep)
5	Severity Classification	steps-c/step-05-severity-classify.md	Yes
6	Report	steps-c/step-06-report.md	Yes
7	Workflow Health Check	steps-c/step-07-health-check.md	Yes

Invocation Contract

Aspect	Detail
Inputs	skill_name [required]
Gates	step-01: Confirm Gate [C]
Outputs	drift-report-{timestamp}.md with drift_score and nextWorkflow
Headless	All gates auto-resolve with default action when {headless_mode} is true

On Activation

1. Load config from {project-root}/_bmad/skf/config.yaml and resolve:

   • project_name, output_folder, user_name, communication_language, document_output_language
   • skills_output_folder, forge_data_folder, sidecar_path
   • Generate and store timestamp as YYYYMMDD-HHmmss format. This value is fixed for the entire workflow run.

2. Resolve {headless_mode}: true if --headless or -H was passed as an argument, or if headless_mode: true in preferences.yaml. Default: false.

3. Load, read the full file, and then execute ./steps-c/step-01-init.md to begin the workflow.
