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 | $0.00777 | $0.00777 |
| Opus 5 | $0.00388 | $0.00388 |
| Sonnet 5 | $0.00155 | $0.00155 |
| Haiku 4.5 | $0.00078 | $0.00078 |
Grade A, and why
specmint-core CLAUDE.md 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 8d 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.
How it starts
The opening of the file, as written. The whole thing — 54 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md — Spec Mint Core
Project Overview
Spec Mint Core is a markdown-only universal skill (no build step, no dependencies) that replaces ephemeral AI coding plans with persistent, resumable specs. It ships as a universal skill (SKILL.md) that works with Claude Code, Codex, Cursor, Windsurf, Cline, and Gemini CLI via npx skills add.
Knowledge base
Architectural details and distribution context for the Mint family live in the ngvoicu-sme brain. Read and write through kluris (never edit brain files by hand — the skill enforces an approval protocol):
/kluris-ngvoicu-sme— Claude Code skill (search, learn, remember, create)kluris search "<query>" --brain ngvoicu-sme— direct search
Topics relevant to this repo: specmint-core overview, architecture, core-vs-tdd differences, distribution, evals.
Architecture
The skill has two conceptual layers:
Skill layer — SKILL.md (the universal skill that drives the full workflow) and references/researcher.md (deep-research subagent brief, spawned via the Task tool during forge). AI tools read these markdown files as behavioral instructions.
Data layer — .specs/ directory created in the consuming project root (not this repo). All tools share this directory. SPEC.md frontmatter is authoritative; registry.md is a denormalized index for quick lookups. See references/spec-format.md for the full format specification.
File Relationships
These files must stay in sync — changing one without the other will cause behavioral drift:
| Source of truth | Must match |
|---|---|
references/spec-format.md |
Spec format rules in SKILL.md |
SKILL.md |
Behavioral contracts in references/command-contracts.md |
skills/specmint-core/SKILL.md is a symlink to ../../SKILL.md — never replace it with a real file.
Key Conventions
CLAUDE.md,AGENTS.md, and.specs/are intentionally untracked in this repoAGENTS.mdprovides Codex-specific guidelines (seeSKILL.mdfor details)SKILL.mdmust work for all AI tools — keep its behavior tool-agnostic- Spec format details (IDs, task codes, phase markers, sections) are in

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.

specmint-core CLAUDE.md is an instructions file published in the GitHub repository ngvoicu/specmint-core (12 stars, last pushed 2mo ago), licensed MIT. It adds 777 tokens to every session, about $0.0039 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 2026-08-30.
