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 | $0.00582 | $0.00582 |
| Opus 5.5 | $0.00233 | $0.00233 |
| Sonnet 5.5 | $0.00116 | $0.00116 |
| Haiku 4.5 | $0.00058 | $0.00058 |
Grade A, and why
hades-gate 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 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.
How it starts
The opening of the file, as written. The whole thing — 47 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
What This Is
Hades Gate is a meta-framework for turning ideas into code. It provides the Architect role: analyzing intent, understanding project context, and proposing six distinct implementation paths (The Hexalogy) plus a synthesis.
The primary delivery mechanism is a Claude Code skill (/hades). The legacy path uses a Python CLI + Gemini API - documented in GEMINI.md.

History Logging
After each /hades run, the skill automatically saves a session record to .hades/YYYY-MM-DD-HHMM-slug.md in the current working directory, where slug is a 3-word-max summary of the intent. The file captures the user's inputs (intent, scope, constraints) and the full Hexalogy output.
The skill also ensures .hades/ is added to .gitignore on first use - history files are local and should never be committed.
The Skill
The /hades skill is installed to ~/.claude/plugins/cache/local/hades/1.0.0/ and reads its user-tweakable config from:
~/.claude/hades/papyrus.md- proposal output structure~/.claude/hades/manifesto.md- quality standards
When modifying the skill, update claude-skill/skills/hades/SKILL.md in this repo. Commit and push, then re-run install-skill.sh to pick up changes (the installer pulls from GitHub).
The Proposal Format (Papyrus)
Every ignition produces 6 core paths (The Hexalogy) plus one synthesis:
- Option A - The Spark: minimal friction, immediate result
- Option B - The Weave: leveraging existing infrastructure
- Option C - The Apex: high quality, clean architecture
- Option D - The Echo: proven standard patterns
- Option E - The Rift: experimental, outside-the-box
- Option F - The Chimera: flashy results, pragmatic interior
- The Synthesis: curated convergence of the strongest elements
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.

hades-gate CLAUDE.md is an instructions file published in the GitHub repository IGPenguin/hades-gate (1 stars, last pushed 1mo ago), licensed MIT. It adds 582 tokens to every session, about $0.0023 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.
