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 | $0.00867 | $0.00867 |
| Opus 5.5 | $0.00347 | $0.00347 |
| Sonnet 5.5 | $0.00173 | $0.00173 |
| Haiku 4.5 | $0.00087 | $0.00087 |
Grade A, and why
safeclaw 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 1mo 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 — 99 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SafeClaw
Sandboxed Docker container running Claude Code, accessible via a web terminal.
See architecture.md for full design details.
Testing end to end
After making changes, rebuild and test:
./scripts/build.sh
./scripts/run.sh
This opens http://localhost:7681 in the browser. Verify:
- Claude Code launches automatically with bypass permissions
- Confirm it shows the correct model (Opus 5.5) and doesn't ask for login
- Send a message and confirm it gets a response
Multiple sessions
Run multiple isolated sessions with -s:
./scripts/run.sh -n # default on port 7681
./scripts/run.sh -s work -n # safeclaw-work on next available port
./scripts/run.sh -s research -n # safeclaw-research on next available port
Mounting local projects
Use -v to mount a local directory into the container. Keep the same folder name inside the container for clarity:
./scripts/run.sh -s myproject -n -v /path/to/myproject:/home/sclaw/myproject
This mounts the project at /home/sclaw/myproject inside the container. Use the same folder name (not a generic "project") so it's clear which project you're working with. If the container already exists, it will be recreated with the new mount.
Research sessions
For web research or any task requiring URL fetching, use a SafeClaw container instead of doing it directly on the host. The -q option sends a query directly to Claude Code inside the container:
./scripts/run.sh -s research -n -q "Research Inngest and explain how durable execution works"
This starts the container (or reuses an existing one) and sends the query to Claude Code running inside it.
Dashboard
Start the dashboard to manage all sessions:
npx nodemon dashboard/server.js
Always use nodemon during development for auto-restart on changes.
Opens at http://localhost:7680. Shows all sessions with:
- Start/stop/delete buttons
- Live iframes of active sessions
- Auto-refreshes via Docker events (SSE)
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.

safeclaw CLAUDE.md is an instructions file published in the GitHub repository ykdojo/safeclaw (186 stars, last pushed 1mo ago), licensed MIT. It adds 867 tokens to every session, about $0.0035 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.
