Audit Skill Lifecycle

Deep semantic validation of how skills interconnect, what they load, what they produce, and whether the resulting call graph forms a coherent, non-contradictory workflow.

Purpose

This audit traces every outbound reference from skills, agents, commands, and data files within a plugin to evaluate whether the resulting graph is coherent, complete, and non-redundant. It performs semantic validation beyond structural checks, answering whether the wiring makes sense given what each component claims to do.

This is NOT structural validation (that's what NamespaceReferenceValidator and /plugin-creator:assessor do). This is semantic validation of the skill lifecycle itself.

When to Use

Invoke this skill when:

• Preparing plugin for marketplace submission (semantic quality gate)
• Debugging why skill workflows fail to achieve stated goals
• Identifying instruction contradictions across related skills
• Finding duplicated content that should be extracted to shared references
• Detecting circular skill loading that could cause infinite recursion
• Analyzing whether skills in a domain form a complete lifecycle
• Discovering manual command sequences that should be scripted

Workflow

Step 1: Discovery

Scan plugin structure to identify all skills, agents, commands, and reference files. Build initial inventory:

• Skill directories containing SKILL.md files
• Agent .md files in agents/ directory
• Command .md files in commands/ directory
• Reference files loaded by skills
• Data files (JSON, YAML, markdown tables) consumed by skills

Extract portable /plugin:skill activations and plugin:agent dispatches to build the outbound dependency graph.

Step 2: Analysis — Run Audit Dimensions

Execute 7 audit dimensions as defined in references/skill-lifecycle-audit.md. Each dimension analyzes a different aspect of semantic coherence:

Dimension	Checks	Output Type
Call Chain Completeness	For each skill: does it load components that actually provide the capabilities it needs?	Call graph with annotations: SUPPORTED / PARTIAL / UNSUPPORTED / MISSING
Bidirectional Lifecycle Coherence	For skills in same domain: are references bidirectional where expected? Do producers know about consumers?	Bidirectional reference matrix per domain with one-directional reference flags
Circular Loading Detection	Trace all Skill() references to find direct/indirect cycles and self-references	List of cycles with full chain (A→B→C→A)
Duplicated Datasets	Scan for identical/near-identical content blocks appearing in multiple skills (>10 lines, >80% similarity)	List of duplicated blocks with source locations and extraction recommendations
Instruction Contradictions	Compare instructions across skills in same domain, detect opposing guidance, distinguish guarded vs unguarded contradictions	Contradiction pairs with file:line references and guard status
Scriptable Command Sequences	Identify multi-step shell command patterns that parse output and make decisions	List of scriptable sequences with complexity reduction estimates
Self-Referential Pattern Learning	Classify discovered issues by detection pattern, re-scan using new patterns until no new patterns emerge	patterns.md catalog with pattern definitions and all instances

Step 3: Report Generation

Write audit artifacts to .plugin-creator/audits/ directory:

• audit-report-{slug}.md — Full findings organized by dimension with severity (error/warning/info)
• call-graph-{slug}.md — Visual call graph (mermaid format) with annotations
• patterns.md — Self-referential pattern catalog updated with newly discovered patterns from this audit
• recommendations.md — Prioritized actionable fixes

Each finding includes:

• File path and line number
• The specific text that triggered the finding
• The audit dimension that detected it
• Severity: error (broken workflow), warning (incomplete workflow), info (optimization opportunity)
• Whether the finding was confirmed by a specialist delegation

Audit Dimensions

1. Call Chain Completeness

For each skill, verify:

• What does this skill claim to do? (from description and body)
• What other skills/agents/commands does it invoke?
• For each invoked component: does that component's description and capability actually support what the caller needs from it?
• Are there steps in the workflow that require capabilities not provided by any loaded component?

Returns call graph per skill with capability match annotations.

2. Bidirectional Lifecycle Coherence

For each skill in a domain (e.g., "Python code quality"):

• Which other skills in same domain reference it?
• Which other skills SHOULD reference it but don't?
• Is there a producer-consumer relationship where the producer doesn't know about the consumer?

Example: If stinkysnake identifies code smells and delegates remediation, does the remediation agent know to invoke stinkysnake when doing code quality review? If not, lifecycle has a gap.

Returns bidirectional reference matrix per domain with one-directional reference flags.

3. Circular Loading Detection

Trace all /plugin:skill references to build the directed graph. Identify:

• Direct cycles: A loads B, B loads A
• Indirect cycles: A loads B, B loads C, C loads A
• Self-references that could cause infinite recursion during activation

Returns list of cycles with full chain notation.

4. Duplicated Datasets

Scan all skill bodies and reference files for:

• Identical or near-identical content blocks appearing in multiple skills
• Content that could be extracted into shared reference file loaded by multiple skills
• Copy-paste indicators: identical code fences, identical tables, identical instruction blocks

Threshold: Content blocks greater than 10 lines appearing in 2 or more skills with greater than 80% similarity.

Returns list of duplicated blocks with source locations and recommendation for extraction.

5. Instruction Contradictions

Compare instructions across skills operating in same domain:

• Identify pairs of instructions giving opposing guidance
• Check whether contradictions are guarded by conditions (e.g., "for Python 3.9" vs "for Python 3.11+")
• Flag unguarded contradictions as errors

Guarded contradictions (acceptable):

• Skill A: "Use List[str] type hints" (within Python 3.9 compatibility section)
• Skill B: "Use list[str] type hints" (within Python 3.11+ section)

Unguarded contradictions (errors):

• Skill A: "Always use Dict[str, Any] for type hints"
• Skill B: "Use dict[str, Any] for type hints"
• Neither specifies Python version condition

Returns contradiction pairs with file:line references and guard status.

6. Scriptable Command Sequences

Identify patterns where skill instructs AI to:

1. Run shell command
2. Parse the output
3. Make decision based on output
4. Run another command with arguments derived from step 3

These multi-step command sequences are candidates for wrapping in Python script that handles argument validation, environment checks (tool availability, correct versions), proper error handling, and structured output.

Returns list of scriptable sequences with steps involved, file:line location, and estimated complexity reduction.

7. Self-Referential Pattern Learning

As audit discovers issues:

1. Classify each issue by detection pattern that found it (e.g., "one-directional domain reference", "unguarded Python version contradiction")
2. Record pattern with description and example
3. Re-scan all already-audited skills using newly discovered pattern
4. Repeat until no new patterns emerge

Returns patterns.md file listing all discovered patterns with: pattern name, description, detection heuristic, and all instances found.

Tier Strategy

Not all issues require same depth of analysis. The audit uses 3-tier approach:

Tier 1: Structural Scan (fast, automated)

• Build call graph from regex extraction of Skill/Task/@ references
• Detect cycles, missing targets, one-directional references
• Identify duplicated content blocks via text similarity

Tier 2: Semantic Analysis (AI reasoning required)

• Read skill descriptions and bodies to understand intent
• Evaluate whether invoked components actually provide needed capabilities
• Detect instruction contradictions with context awareness

Tier 3: Specialist Delegation (for specific issue types)

When Tier 2 identifies potential problem requiring domain expertise:

• Contradictions in Python typing advice → delegate to agent that reads relevant PEPs and Python version docs
• Circular dependency that might be intentional → delegate to agent that evaluates whether cycle serves valid recursive workflow pattern
• Duplicated content that might be intentionally different → delegate to agent that does fine-grained diff analysis

Each specialist delegation returns verdict: CONFIRMED_ISSUE, FALSE_POSITIVE, or NEEDS_HUMAN_REVIEW.

What This Audit Does NOT Do

• Does NOT fix issues (that's separate workflow)
• Does NOT validate namespace references resolve to files (that's NamespaceReferenceValidator in pre-commit hook)
• Does NOT validate frontmatter schema (that's skilllint)
• Does NOT replace /plugin-creator:assessor (which does structural assessment for refactoring planning)
• Does NOT judge whether content inside one skill earns its place (that's /skill-lapidary:skill-lapidary, which prunes a single skill against its own goals). Dimension 4 finds the same block repeated across two or more skills — a shared-reference extraction handled by /plugin-creator:shared-content-references. Duplication within one skill, and prose serving no goal, are outside this audit's scope.

This audit answers: "Given that all files exist and all references resolve, does the resulting system actually work as a coherent whole?"
