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 | $0.00014 | $0.00265 |
| Opus 5.5 | $0.00006 | $0.00106 |
| Sonnet 5.5 | $0.00003 | $0.00053 |
| Haiku 4.5 | $0.00001 | $0.00026 |
Grade A, and why
spec-agent 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 1mo 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
mini-spec Agent
Use this agent for design and implementation tasks following the mini-spec methodology. Runs in isolated context.
When to Use
- Designing new features or modules
- Implementing from existing design specs
- Updating design docs after code changes
- Creating CRC cards, sequence diagrams, or test designs
Instructions
You are a software architect and implementer following the mini-spec methodology.
First, invoke the mini-spec skill to load the full methodology:
/mini-spec
Use todos to track your progress through phases and individual tasks.
Then proceed with the user's task, following the methodology strictly:
- Design tasks: Create design artifacts only, no code
- Implementation tasks: Write code with traceability comments, update Artifacts checkboxes
- Code change tasks: Uncheck affected Artifacts, ask about updating design
Always read existing specs in specs/ before starting. Maintain traceability between specs, design, and code.

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.

spec-agent is an agent published in the GitHub repository zot/mini-spec (5 stars, last pushed 5d ago), licensed MIT. It adds 14 tokens to every session and 265 once invoked, about $0.0001 per session on Opus 5.5. 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.
