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 | $0.00122 | $0.01319 |
| Opus 5.5 | $0.00049 | $0.00528 |
| Sonnet 5.5 | $0.00024 | $0.00264 |
| Haiku 4.5 | $0.00012 | $0.00132 |
Grade A, and why
aether-cli 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.
How it starts
The opening of the file, as written. The whole thing — 112 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Aether CLI
Aether's CLI has two operating modes. Knowing which you need is the entire mental model.
1. Standalone (works without GUI)
Flags start with --. Read/write files directly, no running process required.
aether --generate ~/wallpapers/forest.jpg # extract + apply theme
aether --extract-palette ~/wallpapers/forest.jpg # extract only, no apply
aether --list-blueprints
aether --apply-blueprint my-theme
aether --color-info '#8b3a62' # all reps of a color
aether --contrast '#8b3a62' '#ffffff' # WCAG ratio + grade
aether --palette-from-color '#8b3a62' # derive 16-color palette
aether --import-base16 ./catppuccin-mocha.yaml
Exits 0 on success, 1 on error. Errors go to stderr unless --json is set (then {"error": "..."} on stdout).
2. Remote control (requires running GUI)
Subcommands without leading --. Talk to the GUI over a Unix socket.
aether status # live editor state — palette, lightMode, mode, wallpaper
aether extract ~/w/forest.jpg # load wallpaper into the editor
aether set-color 4 '#89b4fa' # change palette slot 4
aether adjust --vibrance 0.3 --saturation -0.1
aether set-mode pastel
aether apply # write theme files and reload apps
aether toggle-light-mode
aether load-blueprint my-theme # load into editor (does NOT apply)
aether apply-blueprint my-theme # load AND apply in one step
aether set-wallpaper ~/w/forest.jpg
If the GUI isn't running, these fail with a socket error. Launch aether first or run the non-dash variants.
aether status returns what the editor currently shows (as of the state-sync feature) — edits in the GUI propagate to the Go state within ~300ms of the last change. Before that feature, status was stale after GUI edits; don't write scripts assuming the old behavior.
Extraction modes
The mode controls the palette-generation strategy in extraction/. Pass with --extract-mode to the standalone commands or set-mode via IPC:
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.

aether-cli is a skill published in the GitHub repository omacom/aether (776 stars, last pushed 5d ago), licensed MIT. It adds 122 tokens to every session and 1,319 once invoked, about $0.0005 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 2026-08-30.
