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 5.1 | $0.00223 | $0.04454 |
| Opus 5.5 | $0.00089 | $0.01782 |
| Sonnet 5.5 | $0.00045 | $0.00891 |
| Haiku 4.5 | $0.00022 | $0.00445 |
Grade A, and why
cloudflare-artifacts-interface 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 5d 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 — 286 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Cloudflare Artifacts Interface
Status: Draft (2026-10-25). Built from Cloudflare's Artifacts docs (pages last updated between 2026-04-25 and 2026-10-22). Artifacts is in open beta (since 2026-10-01). Tested live 2026-10-25: token verification; listing and getting namespaces; listing and creating repos; minting write tokens; header-auth push from a local clone; Worker-side clone, commit, and concurrent push with isomorphic-git; REST log reads; and the credential behavior in Gotchas. Not yet tested: fork, import, delete, and token revocation. Anything marked (verify) is a belief to confirm on first use. When a live call disagrees with this file, the live call wins. Fix the file.
Artifacts is Git hosting built for agents. Each repo is an isolated Git service with its own remote URL, its own tokens, and durable, replicated storage. You can make one repo per agent, session, task, or user, millions of them, and any git client can clone and push.
"Give this agent its own workspace", "fork the baseline for this session", "let the reviewer read it but not push", "what's in that repo's README?", "clean up last week's session repos".
0. Resolve the account first
Read config/private.json (gitignored; shape in config/private.example.json).
It says which Cloudflare account to use, which environment variables hold
the account ID and API token and where they're loaded from, which namespaces
exist and what each is for, and the repo naming pattern.
- If the file or the account entry is missing, say so and ask. Don't guess. Repos created in the wrong account are billed to it and visible to it.
- Never copy a value from that file into this one. This skill is public.
- Never print a token. To check one exists, print the variable's name.
The model
| Thing | What it is |
|---|---|
| Namespace | Top-level container. Groups repos by environment, tenant, or shard. Created implicitly by the first repo that names it, or explicitly (needed to set a jurisdiction). Name: 2–63 chars, starts with a letter or digit, then letters, digits, ., _, - |
| Repo | One isolated Git service. Address = namespace + name, unique within the namespace. APIs also return an opaque repo id |
| Remote | https://<ACCOUNT_ID>.artifacts.cloudflare.net/git/<namespace>/<repo>.git. Use the remote returned by the API, never a hand-built one |
| Repo token | art_v1_<40 hex>?expires=<unix seconds>. Scoped to one repo, read or write, TTL 60 s to 1 year |
| Fork | A new repo starting from another's history, then diverging, with its own tokens. read_only and default_branch_only options |
| Read-only repo | A repo flagged read_only at create, fork, or import: a fixed baseline nobody can push to |
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

cloudflare-artifacts-interface is a skill published in the GitHub repository lossless-group/lossless-agent-skills (4 stars, last pushed 2d ago), licensed MIT. It adds 223 tokens to every session and 4,454 once invoked, about $0.0009 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 2026-10-26.
