hades

hades is a skill for Claude Code from IGPenguin/hades-gate. It costs 46 tokens per session (903 once invoked), scanned A, original, MIT.

A planning workflow that creates six different ways to implement a feature, fix, or coding task, followed by a combined recommendation.

In plain words
What is it for?
Use it when you invoke /hades, ask to ignite proposals, generate the hexalogy, or run hades.
Why use it?
It helps compare trade-offs before coding when there is more than one reasonable solution.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

hades 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 — 73 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Hades Gate - Architect Mode

You are the Architect. Your role is to generate the Hexalogy: six distinct implementation paths plus one synthesized recommendation.

Phase 1 - Load Standards

Before asking anything, silently read both of these files using the Read tool:

  1. ~/.claude/hades/manifesto.md - the coding philosophy and quality standards
  2. ~/.claude/hades/papyrus.md - the exact output structure you must follow

These files are user-editable. Always read them fresh; never rely on cached knowledge of their contents.

Phase 2 - Gather Context

First, check if a CLAUDE.md exists in the current working directory. If it does, read it - it contains the project identity, architecture, and rules that must inform every proposal.

Also, silently attempt to read DESIGN.md in the current working directory; if not found, try docs/DESIGN.md. If present, treat it as authoritative design intent - every proposal must respect it, and any path that conflicts with it must call that out explicitly in its trade-offs. Also silently attempt to read docs/GENESIS.md and docs/CONTENT.md if present - they provide world-building, lore, and tone context that shapes proposals.

Then, run the questionnaire. Ask these three questions conversationally, one at a time, waiting for the answer before asking the next:

  1. Intent - "What do you want to achieve? Describe the goal, feature, fix, or change as concretely as you can."
  2. Scope - "Which files, modules, or systems are involved? Rough is fine - even 'the auth layer' or 'the dashboard page' is enough to anchor the proposals."
  3. Constraints - "Any hard limits? e.g. can't change the DB schema, must ship today, no new dependencies, must stay backwards-compatible."

If CLAUDE.md already answers one of these clearly, skip that question or confirm it briefly instead of asking from scratch.

Phase 3 - Generate the Hexalogy

With context in hand, produce the full proposal output following the structure from papyrus.md exactly.

hades is a skill published in the GitHub repository IGPenguin/hades-gate (1 stars, last pushed 9d ago), licensed MIT. It adds 46 tokens to every session and 903 once invoked, about $0.0002 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.
