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 | $0.07455 | $0.07455 |
| Opus 5.5 | $0.02982 | $0.02982 |
| Sonnet 5.5 | $0.01491 | $0.01491 |
| Haiku 4.5 | $0.00745 | $0.00745 |
Grade A, and why
vox 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 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 — 274 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Vox
Part of Punt Labs. This repo must be checked out inside the punt-labs/ workspace meta-repo so that org-wide configuration loads via Claude Code's ancestor directory walk:
punt-labs/CLAUDE.md— org workflow, delegation model, beads issue tracking, tool configurationpunt-labs/.claude/rules/python-*.md— 19 Python OO coding rules, scoped viapaths:frontmatter (load on-demand when.pyfiles are touched)punt-labs/.envrc— git identity, beads DB connection, API keys from platform keychainpunt-kit/standards/— canonical reference docs
If cloned outside the workspace, these rules and configuration will not be present.
OO Python standards adopted 2026-05-13. The codebase does not yet fully comply. Every commit must improve OO scores (make check-oo), never regress. Do not match existing code patterns that violate the rules — write new code to the standard and improve touched files incrementally.
Text-to-speech CLI, MCP server, and Claude Code plugin. Supports ElevenLabs (premium), AWS Polly, and OpenAI TTS.

Mandatory Reading
Source-of-truth documents, @-imported so they load into context at session
start. Read them before writing code.
@docs/WORKFLOW.md @../punt-kit/standards/architecture.md @../punt-kit/standards/oo.md @../punt-kit/standards/python.md
WORKFLOW.md is the three-loop development process (backlog → PR → mission),
with pseudocode and an entry/exit Z schema at each level. The
punt-kit/standards imports are the org's canonical engine-and-clients
architecture, object-oriented stance, and Python standard (including the OO
ratchet vox already runs) — cross-repo (external) imports, so the first load
may ask for approval.
Architecture
How synthesis works
An agent (or human) calls an MCP tool or CLI command requesting speech. The request flows through the thin client layer (client.py → WebSocket → voxd). The daemon selects a provider (ElevenLabs > OpenAI > Polly > platform fallback), synthesizes audio, optionally caches the result (content-addressed by text+voice+provider via MD5), and plays it through the system audio stack (afplay on macOS, ffplay on Linux). Long texts are split by core.py into sentence-boundary chunks and synthesized in parallel.
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.

vox CLAUDE.md is an instructions file published in the GitHub repository punt-labs/vox (3 stars, last pushed yesterday), licensed MIT. It adds 7,455 tokens to every session, about $0.0298 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.
