Utility Pm Skill Validate

Audits an existing pm-skills skill against structural conventions and quality criteria. Produces a structured validation report with pass/fail checks, severity-graded findings, and actionable recommendations. Use when checking whether a skill meets repo standards before shipping or after making changes.

What this skill tells the agent

PM Skill Validate

This skill audits an existing pm-skills skill against the repo's structural conventions and quality criteria. It produces a validation report that a human can scan and that utility-pm-skill-iterate can consume as input.

The validator checks two tiers:

  • Tier 1 (Structural) - deterministic checks that mirror CI: frontmatter, naming, file presence, description word count.
  • Tier 2 (Quality) - LLM-assessed coherence checks: does the output contract reference the template? Is the example complete? Are checklist items testable?

When to Use

  • After creating a skill with utility-pm-skill-builder, before shipping
  • After manually editing a skill, to confirm it still passes conventions
  • Before running utility-pm-skill-iterate, to identify what needs improvement
  • When a convention changes, to audit which skills need updating (batch mode)
  • When reviewing a contributed skill for quality and completeness

When NOT to Use

  • To create a new skill from scratch -> use utility-pm-skill-builder
  • To fix or improve a skill -> use utility-pm-skill-iterate (feed it this report)
  • To run CI checks in a pipeline -> use scripts/lint-skills-frontmatter.sh (this skill is for interactive, deeper-than-CI validation)
  • To audit the whole catalog rather than one skill -> use utility-pm-skill-auditor. This skill goes deep on a single skill; the auditor goes wide across the repo and aggregates cross-cutting findings.

Instructions

When asked to validate a skill, follow these steps:

Step 1: Identify the Target

Accept the skill name in any form:

  • Directory name: deliver-prd
  • Full path: skills/deliver-prd/SKILL.md
  • Slash command: deliver-prd

Resolve to the canonical directory path: skills/{name}/.

If the skill directory does not exist, report immediately:

# Validation Report: {input}
Result: FAIL
Skill directory `skills/{input}/` does not exist.

Batch mode: If the input is --all, run Tier 1 structural checks across all skills and produce a summary table (see Step 5). Do not run Tier 2 in batch mode.

Step 2: Read Skill Files

Read all files in the skill directory:

FileRequiredPurpose
SKILL.mdyesFrontmatter + instructions
references/TEMPLATE.mdyesOutput template
references/EXAMPLE.mdyesWorked example
HISTORY.mdnoVersion history (if present)
evals/trigger-fixtures.jsonnoRouting-eval fixtures (B-4); present for roster skills
evals/output-scenarios/*.mdnoOutput-quality scenarios (B-7); present for evaled skills

Also read:

  • The corresponding command file: commands/{command-name}.md
  • The AGENTS.md entry for this skill

If reading files is not possible (MCP/embedded environment), ask the user to paste the content of each file before proceeding (see Degraded Mode).

Step 3: Run Tier 1 - Structural Checks

Run these deterministic checks. Each produces a PASS or FAIL line.

frontmatter-at-byte-zeroFirst line of SKILL.md, references/TEMPLATE.md, references/EXAMPLE.md is exactly ---Line 1 is the opening --- fence with no preceding HTML comment, BOM, or whitespace. Severity: FAIL. Reference: library/skill-output-samples/SAMPLE_CREATION.md Section 5.

If absent: INFO (not in the trigger-eval roster, or fixtures not yet authored). Authoritative gate: scripts/check-trigger-fixtures.mjs.
eval-output-scenariosOutput scenarios present + well-formed (B-7)If evals/output-scenarios/*.md exist: each has scenario/skill/family frontmatter, skill matches dir, family maps to an existing docs/internal/eval-rubrics/{family}.md, body >=100 chars. If absent: INFO (not yet output-evaled). Authoritative gate: scripts/check-output-eval-assets.mjs.
reciprocal-boundary-pointersDeclared collision pairs cross-point (C-5)If the skill appears in COLLISION_PAIRS (scripts/check-trigger-fixtures.mjs): its When NOT to Use names each partner AND each partner's When NOT to Use names it back. FAIL if a declared pair is one-directional. If not in any pair: PASS. Authoritative gate: scripts/check-reciprocal-boundary-pointers.mjs.

Step 4: Run Tier 2 - Quality Checks

Run these LLM-assessed checks. Each produces a PASS, WARN, or INFO line. Tier 2 findings are capped at WARN unless objectively grounded (placeholder leakage is the exception - it can FAIL).

Check IDWhat to assessHow to assessMax severity
output-contract-coverageSKILL.md references the templateCheck for explicit reference to references/TEMPLATE.md or "use the template" in an Output section. Accept either pattern as valid. WARN only if template is not referenced at all.WARN

placeholder-leakageNo leftover scaffolding in any shipped fileScan SKILL.md, TEMPLATE.md, and EXAMPLE.md for: [Placeholder] or [Feature Name] patterns, <!-- ... --> HTML comments (except the license header), template guidance blockquotes that should have been removed, and authoring notes like "TODO" or "FIXME". FAIL if any are found - this is objectively grounded.FAIL
