Audit Skill Completeness

Core Principle

The primary evaluation question is: "Does this skill have everything it needs to achieve its stated purpose reliably?"

Scripts, references, and assets are extension patterns — each is warranted when the skill's purpose calls for it and unnecessary when it does not. Their absence is only a gap when the purpose requires them. A small, complete, purpose-aligned skill scores as complete; a skill with unused scripts and padding scores lower than one with clear, sufficient instructions.

When to Use

• Pre-marketplace publication review — verify skill meets quality standards
• Post-creation quality check — evaluate newly created skills
• Skill improvement planning — identify specific quality gaps
• Marketplace readiness assessment — determine if skill is publication-ready

Workflow

Step 1: Discovery

Read the skill directory structure:

skill-path/
├── SKILL.md          # Required - main skill definition
├── scripts/          # Optional - executable automation (when warranted)
├── references/       # Optional - supporting documentation (when warranted)
└── assets/           # Optional - reusable output resources (when warranted)

Actions:

1. Verify SKILL.md exists; report error and exit if missing
2. Read SKILL.md frontmatter and body
3. Note any scripts/, references/, assets/ directories and their contents

Step 2: Classify purpose type

Classify the skill into one of these purpose types based on the frontmatter description and body:

Purpose Type	Characteristics	Scripts	References	Assets
Behavioral / enforcement	Teaches Claude how to approach a problem; enforces standards or constraints through instructions	Not warranted — behavior is internalized, not scripted	Only if domain-specific lookup needed	Not warranted
Tool / format wrapping	Wraps fragile operations on file formats (DOCX, PDF, XLSX, images)	Warranted — fragile transforms benefit from deterministic scripts	Warranted — format specs, schemas	Often warranted — templates
Workflow orchestration	Multi-step process coordination; skill-creation, plugin lifecycle	Often warranted — scaffolding scripts useful	Often warranted — process patterns	Sometimes
Reference / knowledge	IS the reference material; provides domain knowledge	Not warranted	The reference files ARE the product	Not warranted
Domain expertise	Encodes expert conventions (financial modeling, legal drafting)	Not warranted	Warranted — lookup tables, standards	Not warranted

If the skill spans multiple types, apply the union of warranted categories.

Step 3: Evaluate agentskills.io best practices (primary)

Apply the best-practice checks from ./references/skill-completeness-checklist.md — section "agentskills.io Best Practice Checks". Rate each PASS / PARTIAL / FAIL with evidence from SKILL.md.

Check	Question
1. Approach vs Output	Is the skill scoped to a class of problems or a narrow one-shot recipe?
2. Lean Instructions	Does the skill over-specify, adding rules that narrow behavior without improving outcomes?
3. Reasoning over Directives	Does the skill explain the why behind its rules, or rely on bare imperatives?
4. Description Trigger Accuracy	Does the description generate a clear should-trigger / should-not-trigger boundary?
5. Bundle Signal	Are repetitive operations bundled, or will the agent re-implement them each run?

For each check: state the verdict, cite specific evidence (file:line where possible), and note what an eval would test.

Step 4: Evaluate structural quality categories (secondary)

The categories below are universal (always scored) or conditional (scored only when warranted by purpose; marked N/A otherwise).

Universal categories:

Category	Evaluates
Preparation	Prerequisites met before work begins
Progression	Concrete steps with right level of control
Verification	Output correctness confirmed before declaring success
Examples	Teaching through demonstration
Anti-Patterns	Explicit "what NOT to do" documentation

Conditional categories — apply warranted test first:

Category	Warranted when...
Scripts	The skill involves operations that are fragile, error-prone, or would be rewritten by the agent each invocation; deterministic code improves reliability
References	The skill requires domain-specific knowledge (API formats, schemas, conventions, standards) that an AI cannot reliably generate from training data
Assets	The skill produces output that uses templates, fonts, images, or boilerplate that should be bundled for use (not read into context)

For each category:

1. Warrant check (conditional categories only — Scripts, References, Assets):
   • Ask: is this category warranted for this skill's purpose type (from Step 2)?
   • If NO → record N/A. STOP. Do not execute steps 2–5. Do not add to score denominator. Do not list absence as a gap. Do not recommend adding it.
   • If YES → continue to step 2.
   • Universal categories (Preparation, Progression, Verification, Examples, Anti-Patterns) always continue to step 2.
2. Read the category definition from ./references/skill-completeness-checklist.md
3. Review checklist items for that category
4. Search SKILL.md and supporting files for evidence
5. Score 0–3 based on rubric (below)
6. Document findings with file:line references

Step 5: Suggest eval scenarios

You do not have the domain context needed to author high-quality evals. Suggest scenarios that a domain expert can use as starting points.

For each best-practice check rated FAIL or PARTIAL, describe 1–2 prompts that would expose the gap (use the eval-type mapping in ./references/skill-completeness-checklist.md).

Additionally suggest:

• 3–5 behavioral scenarios — prompts where the skill would be active; note what the assertion should check (the agent's approach, not exact output)
• 2–3 should-trigger queries — non-obvious prompts where the skill SHOULD activate (tests description trigger accuracy)
• 2–3 should-not-trigger queries — prompts at the edge of scope where the skill SHOULD NOT activate

Format each as a short paragraph: the prompt idea, what makes it a good test, what a passing response demonstrates. Do NOT write JSON — the skill author needs domain knowledge to fill in the assertions.

Step 6: Score and report

Calculate overall structural score. Denominator = 15 (universal) + 3 × (number of applicable conditional categories).

Write report to .tmp/scratch/reports/skill-sync-{slug}-completeness-YYYYMMDD.md. Create .tmp/scratch/reports/ if it does not exist.

Scoring Rubric

Each applicable category is scored 0–3:

Score	Label	Meaning
0	None	Category not addressed — no evidence found
1	Minimal	Basic attempt, significant gaps
2	Adequate	Meets expectations, minor gaps
3	Exemplary	Fully addressed, matches Anthropic quality patterns

Universal category guidelines:

• Preparation (0-3):

  • 0: No environment checks, no input validation
  • 1: Environment checks OR input validation present
  • 2: Both environment checks AND input validation present
  • 3: Full prerequisite verification, input inspection, structured pre-flight

• Progression (0-3):

  • 0: No clear workflow defined
  • 1: Workflow mentioned but steps are vague or incomplete
  • 2: Clear step sequence with decision points
  • 3: Clear steps, decision trees, degree-of-freedom calibration appropriate to task fragility

• Verification (0-3):

  • 0: No verification steps mentioned
  • 1: Manual verification suggested but not specified
  • 2: Verification steps defined with acceptance criteria
  • 3: Explicit error-correction loop (verify → fix → re-verify), expressed either as behavioral instructions Claude follows or as automated scripts — either form satisfies this level

• Examples (0-3):

  • 0: No examples provided
  • 1: Abstract descriptions or pseudocode only
  • 2: Concrete examples covering common cases
  • 3: Examples covering common AND edge cases, with exact input→output pairs

• Anti-Patterns (0-3):

  • 0: No anti-patterns documented
  • 1: Anti-patterns mentioned but not demonstrated
  • 2: Anti-patterns shown with corrections
  • 3: Anti-patterns shown with corrections AND reasoning for why the wrong form fails

Conditional category guidelines (only when warranted):

• Scripts (0-3, or N/A):

  • N/A: Skill's purpose does not involve deterministic or repetitive operations that benefit from scripting
  • 0: Operations clearly need scripting (agent would regenerate the same logic each invocation) but no scripts provided
  • 1: Scripts exist but the operations most likely to be regenerated wastefully remain unscripted
  • 2: Scripts cover the operations the agent would otherwise rewrite each run; eliminates the primary sources of wasted agent turns
  • 3: All deterministic operations that the agent would otherwise regenerate are scripted; scripts are self-documenting (--help) and handle edge cases — the agent never writes boilerplate

• References (0-3, or N/A):

  • N/A: Skill's purpose does not require domain knowledge beyond training data
  • 0: Warranted but no reference material bundled
  • 1: External links only — not bundled for offline use
  • 2: Reference files bundled, organized by topic
  • 3: Reference files linked from the specific workflow steps where they're needed

• Assets (0-3, or N/A):

  • N/A: Skill's output does not depend on templates, fonts, images, or boilerplate resources
  • 0: Output clearly requires bundled resources but none provided — agent generates required materials ad-hoc each invocation
  • 1: Some assets bundled but key output resources the agent needs are still generated ad-hoc
  • 2: Main output resources bundled; agent can produce its primary output without generating supporting materials
  • 3: All output resources the agent needs are bundled; agent never generates supporting materials ad-hoc; asset usage is clearly specified
