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 B, and why

aget-create-skill scanned grade B with 1 finding 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 4d 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.

Skill Creation Process

Step 1: Name Validation

Validate the skill name follows S-V-O convention:

Pattern Valid Examples
/aget-<verb>-<object> ✓ Default /aget-create-skill, /aget-check-health
/aget-<verb> ✓ Intransitive /aget-learn, /aget-checkpoint (grammar examples only; /aget-checkpoint was renamed to /aget-save-state, /aget-learn was never built)
/aget-<phrasal-verb> ✓ Exception /aget-wake-up, /aget-wind-down
Other patterns ✗ Invalid /aget-skill-create (O-V not S-V-O)

Check for existing skill:

ls .claude/skills/ | grep -q "<name>"

If skill exists, STOP and report conflict.

Step 2: Determine Skill Number

Check specs/skills/INDEX.md for next available SKILL-XXX number.

Current registry:

  • SKILL-001 through SKILL-005: Existing
  • SKILL-006: Reserved for /aget-create-project
  • SKILL-007: This skill (/aget-create-skill)
  • SKILL-008+: Available

Step 3: Create Skill Specification

Create specs/skills/SKILL-XXX_<name>.md with:

  1. Purpose section
  2. Requirements (R-SKILL-XXX-001, etc.) in EARS format
  3. Test cases
  4. Traceability section

Step 4: Create SKILL.md

  1. Create directory: .claude/skills/<name>/
  2. Copy structure from templates/skill/SKILL.template.md
  3. Fill in required fields:

Required frontmatter:

---
name: <name>
description: <one-line description>
---

For skills with side effects (file writes, git operations):

disable-model-invocation: true

Instruction format (per L561 - Instruction Asymmetry):

  • Use PROHIBITIVE form: "NEVER", "SHALL NOT", "DO NOT"
  • Avoid affirmative form (~0% compliance)

What this file has done since we first saw it

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.
