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 | $0.00028 | $0.00404 |
| Opus 5 | $0.00014 | $0.00202 |
| Sonnet 5 | $0.00006 | $0.00081 |
| Haiku 4.5 | $0.00003 | $0.00040 |
Grade A, and why
skill-creator 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 7d 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.
What it actually says
Skill: skill-creator
Create a new SuperSpecs skill.
A skill is
A markdown file in .skills/<skill-name>/SKILL.md that an AI agent reads when triggered. Skills are instruction sets, not code.

Brief intro: what you're doing in this phase.
## Inputs
What files or context the agent needs to read first.
## Steps
Numbered, concrete steps. Include:
- What to read
- What to write
- What to verify
- What to report to the user
## Output
What files are created/updated.
## What NOT to do
Explicit prohibitions.
Good skill design
- Concrete steps, not vague instructions. "Read
tasks.mdcompletely" not "understand the plan". - Explicit output. List every file created or modified.
- Stopping conditions. When should the skill ask for input before proceeding?
- Verification steps. What does "done" look like?
- Non-negotiables. What must never be skipped?
After creating
- Place file in
.skills/<skill-name>/SKILL.md - Run
setup.shto symlink into agent directories - Test: open your agent and say "tell me about "
Integration with SuperSpecs lifecycle

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.

skill-creator is a skill published in the GitHub repository fokkerone/superspecs (4 stars, last pushed 2mo ago), licensed MIT. It adds 28 tokens to every session and 404 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
