Sharpagent Skill Contract

SharpAgent Skill Contract — Schema-driven skill scaffolding tool. Generates, validates, and packages SharpAgent-compliant skills with five-factor trust verification, calibration framework hooks, and content safety integration.

SharpAgent Skill Contract v1.0.0

Foundation shovel — Generate, validate, and package all SharpAgent skills. Fusion of Ontology Schema + Skill Creator + Skill Oracle.

When to Use

Use this skill when:

• Creating a new SharpAgent-compliant Skill from scratch
• Validating an existing Skill for contract compliance
• Packaging a Skill for ClawHub publication under SharpAgent
• Upgrading a legacy Skill to SharpAgent standards

What Is a Skill Contract

Every SharpAgent Skill must declare a contract — a YAML block that states:

contract:
  name: sharpagent-five-factor-review
  version: "1.0.0"
  category: analysis
  trust_level: verified            # draft | verified | audited
  reads:
    - InformationSource
    - LearningEntry
  writes:
    - FiveFactorResult
  preconditions:
    - "Must have at least one InformationSource to analyze"
    - "Must have access to web_search or memory_search tool"
  postconditions:
    - "Output contains overall_confidence score (0-10)"
    - "Each of 5 factors has a value"
  calibration:
    default_mode: professional     # warm | professional | deep
    modes_supported: [warm, professional, deep]
  compliance:
    jurisdiction: global           # cn | us | eu | global
    safety_level: standard         # minimal | standard | strict
  lifecycle:
    status: active
    publish_as: SharpAgent

Workflow

Step 1: Scaffold a New Skill

sharpagent scaffold --name sharpagent-five-factor-review --category analysis

Generates:

/sharpagent-skills/sharpagent-five-factor-review/
├── SKILL.md            # Contract + documentation
├── contract.yaml       # Machine-readable contract (auto-derived)
├── scripts/            # Runtime scripts (optional)
├── references/         # Supporting docs (optional)
└── test/               # Validation tests (optional)

Step 2: Validate Contract

sharpagent validate --path ./sharpagent-five-factor-review/SKILL.md

Checks:

• Structural: All required YAML fields present
• Semantic: reads/writes match known ontology types
• Integrity: preconditions reference real capabilities
• Naming: snake_case, no spaces, max 40 chars

{
  "valid": true,
  "warnings": [],
  "errors": [],
  "score": 100,
  "missing_optional": ["scripts/ directory missing"]
}

Step 3: Package for Publication

sharpagent package --name sharpagent-five-factor-review --output ./dist/

Produces:

./dist/sharpagent-five-factor-review.tar.gz
├── SKILL.md
├── contract.yaml
├── scripts/
└── references/

Contract YAML Schema Reference

Top-Level Fields

Field	Type	Required	Default
contract.name	string	✅	-
contract.version	semver	✅	"0.0.1"
contract.category	enum	✅	-
contract.trust_level	enum	✅	"draft"
contract.reads	string[]	✅	[]
contract.writes	string[]	✅	[]
contract.preconditions	string[]	✅	[]
contract.postconditions	string[]	❌	[]
contract.calibration	object	✅	default
contract.compliance	object	✅	default
contract.lifecycle	object	✅	default

Contract Categories

Category	Description	Example Skills
analysis	Analyzes input, produces structured output	Five-factor review
workflow	Multi-step process with gates	Engineering lifecycle
monitor	Periodic scanning and alerting	Intelligence briefing
memory	Storage, retrieval, consolidation	Memory management
scaffold	Code/file generation	Skill creation
integration	External service bridging	API clients

Trust Levels

Level	Meaning	When
draft	Work in progress, unverified	Initial creation
verified	Contract structure validated	After validation
audited	Full five-factor trust audit passed	Community verified

Calibration Modes

calibration:
  default_mode: professional
  modes_supported: [warm, professional, deep]

Mode	Warm	Professional	Deep
Tone	Friendly, supportive	Neutral, precise	Analytical, detailed
Detail	Concise	Balanced	Exhaustive
Use case	User-facing	Internal reports	Research analysis

Integration Points

With Five-Factor Review

• writes: [FiveFactorResult] → Contract schema is consumed by the five-factor review skill
• Contract trust_level is validated using FiveFactorResult as part of skill audit

With Calibration Framework

• contract.calibration block defines which modes are supported
• At runtime, the calibration engine checks contract.calibration.modes_supported

With Content Safety Engine

• contract.compliance block sets safety policies
• safety_level: standard is the minimum for ClawHub publication

Quality Gates

Check	What	Fail action
Schema valid	All required YAML fields present	Block packaging
Type consistency	reads/writes reference known types	Warn
Naming convention	snake_case, ≤40 chars	Warn
Calibration declared	At least default_mode set	Warn
Preconditions non-empty	preconditions list ≥1 item	Warn
Version format	valid semver	Block packaging

Edge Cases

Situation	Action
No reads (standalone)	Allow with warning
reads = writes	Warn (likely mistake)
Type cross-reference fails	Warn + list unknown types
Calibration missing	Set default: professional + standard
Draft trust_level	Allow creation, warn on packaging
SKILL.md has no contract block	Fail validation

Dependencies

• YAML parser (for reading contract blocks)
• jq or Python 3 (for validation scripts)
• tar (for packaging)

Version History

• v1.0.0 — Initial release. Skill Contract scaffolding + validation + packaging.
