Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00213 | $0.02604 |
| Opus 5 | $0.00106 | $0.01302 |
| Sonnet 5 | $0.00043 | $0.00521 |
| Haiku 4.5 | $0.00021 | $0.00260 |
Grade A, and why
add-voice 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 6d 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 — 113 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Add voice
Runs on: local-exec - the happy path runs a local Python setup that writes a gitignored voice/ runtime and serves a local page. On a read-only or cloud surface, explain the steps and the tiers but do NOT claim the install ran or the loop works - it has not until the user runs it locally.
This turns the documented "voice is a DIY mouth and ears" direction (docs/voice-extension.md) into a wired capability the user installs by asking. The OS ships as a complete text brain; this adds a sensory layer on top of the same brain. Nothing here is required.
Check you are in the right skill (say this first if the ask was ambiguous)
"Voice" means two different things in this OS, and "set up my voice" can mean either:
- This skill (add-voice) - SPEAKING and LISTENING. You talk to the OS out loud and hear it answer.
voice-interview- your WRITING voice. It captures how you write so every email, post, and draft sounds like you. Nothing is spoken or heard.
If the user asked with a phrase that could be either ("set up my voice", "voice setup"), say one line before installing anything: "Quick check - do you mean talking to your OS out loud (this), or how your writing sounds (that is voice-interview)?" Do not install a runtime the user did not ask for.
The accessibility floor (the rule that governs the default)
The default install - Tier 0 - must work end-to-end on the one subscription the user already runs the OS in, with no extra API key and no paid service. That is non-negotiable. The brain answers through the reasoning CLI the OS already uses (claude -p by default - no API key, it uses the existing subscription); the browser hears and speaks. Everything past Tier 0 is opt-in and disclosed.
The tiers
| Tier | What it adds | Needs | Default? |
|---|---|---|---|
| 0 | Browser speech-in + speech-out + brain on your one subscription | nothing extra | YES |
| 0-local | Swap browser STT for faster-whisper so speech never leaves your machine | one pip install + a model download | no - opt-in |
| 1 | Realtime, sub-second spoken conversation (Gemini Live front) | a FREE Google AI Studio key | no - opt-in |
| 2 | A premium, higher-quality mouth (ElevenLabs) | a paid key | no - opt-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.
- 6d ago First seen · 113 lines · 213 tokens per session scan A 3677a93ff440
add-voice is a skill published in the GitHub repository ARCASSystems/FounderOS (5 stars, last pushed 23d ago), licensed MIT. It adds 213 tokens to every session and 2,604 once invoked, about $0.0011 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.

alive:system-cleanup
The world feels messy. Stale tasks, orphan folders, v2 remnants, unsaved sessions — entropy is accumulating and needs to be addressed before it compounds. Scans across all walnuts, then surfaces issues one at a time.
alive:world
The human doesn't know what to work on, or wants to see everything at once. They need the big picture — what's active, what's stale, what needs attention. Renders a live world view grouped by ALIVE domain, then routes to open, tidy, find, history, or map.
alive:bundle
Create, share, and graduate bundles — the unit of focused work within a walnut. Manages the full bundle lifecycle from creation through sharing to graduation.
