Governance Model

This project treats important skills as governed assets rather than one-shot prompt files.

Goals

  • keep shared skills trustworthy over time
  • make ownership explicit
  • avoid stale or oversized skill packages
  • define when a skill should evolve, split, or retire

Required Governance Metadata

For reusable or library-grade skills, manifest.json should include:

  • name
  • version
  • owner
  • updated_at
  • review_cadence
  • status
  • maturity_tier
  • lifecycle_stage

Allowed Values

status

  • experimental
  • active
  • deprecated

maturity_tier

  • scaffold
  • production
  • library
  • governed

lifecycle_stage

  • scaffold
  • production
  • library
  • governed

review_cadence

  • monthly
  • quarterly
  • semiannual
  • annual
  • per-release

Governance Rules

1. Owner Required

Any skill meant for reuse must have a named owner or owning team.

2. Review Cadence Required

If a skill is shared, it must declare how often it should be reviewed.

3. Maturity Should Match Rigor

  • scaffold: lightweight, personal, low-governance
  • production: reusable team skill with validation
  • library: curated shared skill with explicit packaging and evals
  • governed: critical or meta-level skill with regression, maintenance, and review expectations

4. Deprecated Skills Need Explicit Intent

Deprecated skills should include a deprecation note or replacement reference in adjacent documentation or manifest extensions.

5. Drift Must Be Observable

Important skills should keep:

  • a regression history
  • visible evaluation results
  • known anti-patterns or failure modes

Governance Actions

Use governance review to decide whether a skill should:

  • stay as-is
  • tighten trigger boundaries
  • split into sibling skills
  • move detail into references/
  • move brittle logic into scripts/
  • be deprecated or replaced

Governance Maturity Scoring

scripts/governance_check.py also computes a maturity score out of 100.

Score Buckets

The governance checker computes a score band in addition to the declared manifest tier. The score band is a diagnostic output, not a replacement for the declared lifecycle tier.

  • 90-100: governed
  • 80-89: production
  • 65-79: reusable
  • 45-64: emerging
  • <45: draft
  • scaffold: no hard minimum
  • production: 80
  • library: 85
  • governed: 90

Score Dimensions

  • metadata integrity
  • ownership and review cadence
  • boundary and eval evidence
  • operational assets
  • maintenance evidence

The score is not a replacement for human review. It is a fast signal that a shared skill is structured enough to be trusted, maintained, and audited. scripts/governance_check.py warns when a declared tier claims more rigor than the score currently supports.

Why This Matters

Most skill systems stop at creation. World-class skill systems also manage:

  • ownership
  • drift
  • maturity
  • deprecation
  • evidence of ongoing quality
