aether: Skill for Claude Code

.claude/skills/aether-docs/SKILL.md

aether-docs is a skill for Claude Code from omacom/aether. It costs 104 tokens per session (543 once invoked), scanned A, original, MIT.

Detailed documentation for the Aether codebase, including architecture decisions, design reasoning, diagrams, feature specifications, historical context, and draft work.

In plain words
What is it for?
It is for researching Aether’s architecture, design choices, features, history, and work in progress.
Why use it?
It provides background that may not be present in the repository, helping an agent understand why the code is structured as it is before making non-trivial changes.

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

aether-docs 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 2mo 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

Aether detailed documentation

The in-repo docs (README.md, docs/*.md, CLAUDE.md) cover only the minimum needed to build, run, and understand the public feature surface. Detailed project documentation lives outside the repo at:

~/Documents/bjarne/projects/Aether

When to consult this folder

  • Before implementing a non-trivial feature — check for existing design docs, prior decisions, or half-finished drafts on the area you're touching.
  • Before architectural changes — look for ADRs or flow diagrams that explain why things are structured as they are.
  • When the user asks "how does X work" or "why did we build X that way" and the answer isn't obvious from code.
  • After a significant design discussion — write a new doc so future work has the context.

How to use

ls ~/Documents/bjarne/projects/Aether
rg "<topic>" ~/Documents/bjarne/projects/Aether

Read relevant files before drafting a plan. Cite the filename when you rely on one.

Writing new docs

When the user asks you to document a design decision, flow, or feature internal:

  • Write to ~/Documents/bjarne/projects/Aether/<topic>.md.
  • Use a short descriptive filename (e.g. palette-extraction-pipeline.md, eyedropper-loupe-design.md, adr-001-split-sidebars.md).
  • Include date headers so the reader can see when something was decided.

Do not put these detailed docs into the repo's docs/ folder — that directory is reserved for user-facing documentation (CLI usage, installation, custom apps, custom templates, wallhaven setup, etc.).

Do not

  • Don't guess at Aether's architecture or history without checking this folder first — the user keeps decisions here rather than in commit messages or PR descriptions.
  • Don't duplicate content from here into the repo.
  • Don't commit anything to git from this folder — it's deliberately outside version control.
Changes

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.
