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 | $0.15201 | $0.15201 |
| Opus 5.5 | $0.06080 | $0.06080 |
| Sonnet 5.5 | $0.03040 | $0.03040 |
| Haiku 4.5 | $0.01520 | $0.01520 |
Grade C, and why
fluidbox CLAUDE.md scanned grade C with 2 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.
Cloud metadata endpointhighServer-side request forgery
One request to 169.254.169.254 can return temporary IAM credentials.
- **ALL control-plane egress rides ONE hardened boundary, and admission happens TWICE** (Phase E, Gap 7; `egress.rs`, `netpolicy.rs` in core). Two hardened clients: `state.egress_http` (broker MCP + discovery + delivery Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
- **Connector OAuth is now a ONE-TIME, browser-bound flow with REUSABLE client identities** (Phase D, invariant 20; `oauth.rs`, migrations 0015/0016). `POST /v1/connections/{id}/oauth/start` (and catalog Connect) returns How it starts

What this is
fluidbox is a control plane that runs AI coding agents in governed, disposable sandboxes. A user registers a versioned agent definition; each run freezes an immutable RunSpec, provisions a fresh sandbox, streams a live event timeline, pauses for human approval (or auto-decides in autonomous mode), and ends with a diff + cost report. PLAN.md is the authoritative design doc and roadmap — read it before making architectural changes. It defines convergence invariants (§2) that every change must preserve.
Hard constraints (from PLAN.md, non-negotiable): fluidbox-authored backend is 100% Rust; the Next.js dashboard is presentation-only (all logic in the Rust API); database is Neon Postgres; OSS/MIT.
Commands
just setup # fresh-clone bootstrap (idempotent): .env + secrets, apps/web/.env.local, pnpm install, runner image
just doctor # preflight — validates every env gotcha below and prints the exact fix
just demo # five-minute no-key first-run: deterministic replay through the real gate (isolated: ports 19790/19791/15434, own volume, .demo/); `just demo-down` removes everything
just replay-build # rebuild the replay runner image after editing images/replay-runner/
just dev # LiteLLM gateway + server + dashboard together
just server # Rust control plane only (migrations auto-run on boot)
just web # dashboard only (Next.js, port 3000)
just gateway-up # start the pinned LiteLLM container (reads .env)
just sandbox-build # rebuild the sandbox runner image after editing images/sandbox-runner/
just check # fmt + clippy -D warnings + test + web build (the full bar)
just e2e # full acceptance: live demo A + governance + git workspaces + api triggers + schedules + github fan-out + capability catalog + connector catalog/oauth + failure paths (owns the stack; stop `just dev` first)
cargo test -p fluidbox-core # fast, no DB needed
cargo test -p fluidbox-db # needs DATABASE_URL (local container Postgres)
cargo test -p fluidbox-core policy::tests:: # a single module's tests
cargo run -p fluidbox-cli -- run --task "…" --repo /path # drive a run from the CLI
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.

fluidbox CLAUDE.md is an instructions file published in the GitHub repository hrishikeshdkakkad/fluidbox (11 stars, last pushed 19d ago), licensed MIT. It adds 15,201 tokens to every session, about $0.0608 per session on Opus 5.5. A static security scan graded it C with 2 findings (cloud metadata endpoint, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
