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 | $0.06020 | $0.06020 |
| Opus 5.5 | $0.02408 | $0.02408 |
| Sonnet 5.5 | $0.01204 | $0.01204 |
| Haiku 4.5 | $0.00602 | $0.00602 |
Grade A, and why
wingthing 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 12d 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 — 410 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Wingthing
What This Is
wt puts AI agent runtimes behind one local control plane. A person uses that
runtime through the CLI or browser. An LLM uses it through MCP. The primary use
case is all of a person's agents in one inventory, for that person and their
agents to operate together. Skills are a secondary feature.

Current Push: One Portal for People and LLMs
An AI must be able to orchestrate wingthing as easily as a human can. This is the primary focus of the current work. Anything a human can do from the terminal or the browser, a model must be able to do through a typed interface with the same authority model and the same audit trail.
The rule: if you ship a capability only a human can drive, it is unfinished.
"One portal" means one resource inventory, authority model, and lifecycle contract. It does not mean every process or file moves to one machine.
- A portal is the client-facing inventory and control surface.
- A wing is the execution runtime and source of truth for local state.
- A session is a persistent interactive terminal.
- A run is a supervised headless task with semantic state.
- An egg is the per-session process, PTY, and sandbox boundary.
- A roost is the self-hosted bundle from
wt roost start: portal/gateway plus an embedded wing.
Browser and MCP adapters must address the same qualified resources. Cross-wing resources need stable portal, wing, kind, and object IDs. Do not add mutable "current wing" state to a server-side MCP session.
Every remote workflow must place execution, workspace, display, credentials,
and durable memory explicitly. Current cwd values refer to existing paths on
the selected wing. Wingthing does not yet synchronize code or memory between
wings, and docs must not imply that it does.
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.

wingthing CLAUDE.md is an instructions file published in the GitHub repository ehrlich-b/wingthing (53 stars, last pushed 12d ago), licensed MIT. It adds 6,020 tokens to every session, about $0.0241 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.
