aget: Skill for Claude Code

.claude/skills/aget-expand-ontology/SKILL.md

aget-expand-ontology is a skill for Claude Code from aget-framework/aget. It costs 55 tokens per session (4,755 once invoked), scanned A, original, Apache-2.0.

A research workflow for expanding SKOS vocabularies, which are structured lists of related concepts and their links. It finds gaps, researches supporting evidence, and adds or improves formal entries.

In plain words
What is it for?
Use it to inspect thin topics, propose additions, research concepts on the web or from a knowledge-base document, and validate the resulting links.
Why use it?
It helps when a vocabulary has missing or weak coverage and new concepts need evidence and connections to existing ones.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

aget-expand-ontology scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

/aget-expand-ontology

Expand this agent's SKOS vocabularies with new web-researched, evidence-backed concepts targeting thin topics. Merged from professional-core v1.5.0 + framework-AGET v1.0.0 + supervisor additions (SKILL-019 spec).

Purpose

Automate the research-informed ontology expansion workflow:

  1. Diagnose: Identify thin topics and KB gaps
  2. Propose: Rank expansion areas by gap size and tier importance
  3. Research: Web-search for best-practice evidenced concepts
  4. Design: Write formal SKOS entries with interlinkage
  5. Enrich: Enhance matched existing concepts with new evidence
  6. Verify: Validate no orphans, topic density improved

Input

Optional parameters after skill name:

Parameter Default Description
--areas N 3 Number of expansion areas to propose
--concepts-per-area N 7 Domain concepts per area
--bridging-per-area N 3 Bridging/interlinkage concepts per area
--vocabulary V Auto (smallest) Target specific vocabulary file
--from-kb <path> None Extract concepts from KB document instead of web search
--dry-run false Output project plan without writing to vocabulary
--skip-web-search false Use KB-only gap analysis (no web research)
--skip-enhance false Skip enhancement of matched concepts during deduplication
--plan false Output structured expansion plan without executing
--summary false Output only summary metrics
--provenance "desc" None Strategic context that triggered this expansion (event, motivation, audience)

Examples:

  • /aget-expand-ontology — Auto-detect thinnest vocabulary, 3 areas, 7+3 concepts each
  • /aget-expand-ontology --vocabulary ontology/ONTOLOGY_personal_ai_systems_v1.0.yaml — Target specific vocabulary
  • /aget-expand-ontology --from-kb knowledge/REPORT.md — Document-driven expansion
  • /aget-expand-ontology --dry-run — Propose expansion without writing
  • /aget-expand-ontology --concepts-per-area 5 --bridging-per-area 2 — Smaller expansion
  • /aget-expand-ontology --provenance "Marcus 1:1 surfaced missing meta-concepts for team topology" — Expansion with strategic context

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
