aget: Skill for Claude Code

.claude/skills/aget-validate-spec/SKILL.md

aget-validate-spec is a skill for Claude Code from aget-framework/aget. It costs 11 tokens per session (732 once invoked), scanned A, original, Apache-2.0.

A specification-checking guide for finding missing, conflicting, or unclear requirements. It uses EARS, a format that writes requirements in clear, testable patterns such as actions triggered by events or conditions.

In plain words
What is it for?
Use it to review software specifications for completeness, consistency, structure, traceability, and testability.
Why use it?
It helps teams detect gaps, inconsistent terms, duplicate IDs, vague requirements, and acceptance criteria that cannot be verified.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter.

This is aget-framework/aget's own configuration. It tells Claude Code how to work on aget itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything aget configures →

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-validate-spec 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 3d 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.

    • Traceability links exist
  2. Check Consistency

    • No contradictions
    • Terminology consistent
    • IDs unique
  3. Check Testability

    • Requirements are verifiable
    • Acceptance criteria clear
    • No vague language
  4. Check Format

    • EARS templates applied
    • Correct SHALL/SHOULD usage
    • Proper structure

Required Sections

  • Scope
  • Requirements (functional)
  • Constraints (non-functional)
  • Traceability

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.
