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 | $0.00131 | $0.03642 |
| Opus 5 | $0.00066 | $0.01821 |
| Sonnet 5 | $0.00026 | $0.00728 |
| Haiku 4.5 | $0.00013 | $0.00364 |
Grade A, and why
bureau scanned grade A with 1 finding 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 3d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 280 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Bureau — the installable browser capability server
Quick start: bureau start
bureau start orchestrates headless Camofox + bureau serve in a single
command.
bureau start # Camofox :9377 + serve :8830, foreground
bureau start --detach # everything in the background, exit 0 if healthy
bureau start bureau-only # Camofox assumed up, starts just serve
bureau start --port 9000 # bureau serve on :9000
bureau start --camofox-port 9400 --detach
bureau start --camofox-cmd "camoufox serve --port 9377" --detach
bureau start --timeout 90 # max delay 90 s (default 60)
Camofox command resolution (in order): --camofox-cmd →
$CAMOFOX_SERVE_CMD → launchctl start com.agentik.camofox (macOS). If
nothing resolves, explicit error with instructions. Idempotent: if Camofox is
already up, it is not respawned.
Bureau is the standalone, shipped product of the browser stack: one daemon
co-located with a stealth Firefox (Camofox), exposing browser capabilities as
MCP-over-HTTP plus a CLI. Same daemon runs three ways behind one
BureauEndpoint contract — bureau serve on the user's machine (this skill),
agentproto-daemon-managed, or as a cloud RuntimeSpec on a Guilde
browser-workstation. Zero @guilde deps; it's its own appliance.
Layout
- App:
projects/browser/apps/bureau— the CLI + serve entrypoint (@agstudio/bureau,bin: bureau). - Invoke:
node projects/browser/apps/bureau/dist/index.js <cmd>(built output), orpnpm --filter=@agstudio/bureau dev <cmd>(tsx watch), or the globalbureaubin if linked. - State:
~/.agentproto/bureau/—sessions/(saved identities, the cookie store),guilde.json(connection),runtime.json(descriptor when hosted). Secrets (platform passwords, gld_ tokens) live in the OS Keychain, never on disk or argv. - Ports: daemon
:8830(MCP/mcp+/watch/<tab>screencast +/health); Camofox REST:9377.
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.

bureau is a skill published in the GitHub repository agentproto/ts (5 stars, last pushed 3d ago), licensed Apache-2.0. It adds 131 tokens to every session and 3,642 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
