Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

deepspace 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 8d 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.

How it starts

The opening of the file, as written. The whole thing — 296 lines — stays where its author put it; the contents beside it link to each section on GitHub.

DeepSpace

DeepSpace is one package for real-time collaborative apps on Cloudflare Workers. It provides auth, RBAC, synchronized records, messaging, integrations, payments, and deploys to <name>.app.space.

This skill is the bootstrap: how to start, how to operate, and how to consult the documentation. The documentation at https://docs.deep.space is the authority for everything else — it is written to be opinionated, so when it recommends an approach, take that as the default rather than one option among many.

One source authority

Every app has exactly one Git authority — DeepSpace source (packaged, commit-first) or GitHub source (manual; deploys ship the local working tree, dirty bytes included). A new app starts unclaimed, then its first source-producing action latches one authority once, permanently: a deploy from a checkout with a selected GitHub remote claims that repository, while the first deepspace push or a deploy without a GitHub remote claims DeepSpace. There is no manual declaration or later transfer. Never run deepspace push before the first GitHub deploy unless the user has chosen DeepSpace source; after a GitHub claim, all DeepSpace source verbs refuse with source_managed_by_github. deepspace app source is read-only (the old setter refuses source_inferred). Never maintain two sources of truth, and read the source-control and workspaces docs before any source, push, pull, or clone operation — the docs, not this skill, state what each verb does under each authority.

Sharing and handing over an app

Collaborators and ownership transfer (deepspace app collaborators …, deepspace app transfer …) change who can deploy, read secrets, and own the app. Read the app-identity guide before either — it states exactly what each grant confers and what a transfer takes away — and treat both as decisions to surface to the user, not steps to run in passing.

How to read the documentation

Consult the docs BEFORE building in an area, not after something breaks. The reading procedure:

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.

deepspace is a skill published in the GitHub repository deepdotspace/deepspace-skill (6 stars, last pushed 6d ago), licensed MIT. It adds 116 tokens to every session and 3,718 once invoked, about $0.0005 per session on Opus 5.5. 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.
