Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00037 | $0.01158 |
| Opus 5.5 | $0.00015 | $0.00463 |
| Sonnet 5.5 | $0.00007 | $0.00232 |
| Haiku 4.5 | $0.00004 | $0.00116 |
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 15d 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.

How it starts
The opening of the file, as written. The whole thing — 149 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/aget-create-skill
Create a new AGET skill following the standard development process per SOP_SKILL_DEVELOPMENT.md.

| Input Pattern | Mode | Behavior |

| Empty or blank | Interactive | Prompt for skill name |
<skill-name> |
Explicit | Create skill with provided name |
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 |
/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:
- Purpose section
- Requirements (R-SKILL-XXX-001, etc.) in EARS format
- Test cases
- Traceability section
Step 4: Create SKILL.md
- Create directory:
.claude/skills/<name>/ - Copy structure from
templates/skill/SKILL.template.md - 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)
Step 5: Update Index
Add entry to specs/skills/INDEX.md:
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.
