octo-html

octo-html is a skill for Claude Code, Codex from Mininglamp-OSS/octo-cli. It costs 67 tokens per session (2,436 once invoked), scanned A, original, Apache-2.0.

Instructions for creating and managing self-contained interactive HTML documents through the Octo HTML service. These documents are published as immutable versions, unlike Octo Docs documents, which use collaborative editing.

In plain words
What is it for?
It covers creating HTML documents, saving their returned identifiers, publishing new versions, and handling metadata and legacy document references.
Why use it?
It prevents mixing two different document systems and their commands. It also defines how to identify a document across later operations.

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

octo-html 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 9d 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.

The opening of the file, as written. The whole thing — 211 lines — stays where its author put it; the contents beside it link to each section on GitHub.

octo-html — interactive HTML documents

This is NOT the octo-docs body-editing domain. octo-cli html … talks to octo-doc, where a document is a self-contained HTML page published as immutable versions. octo-cli docs … talks to the separate CRDT/Yjs backend.

All commands call $OCTO_API_BASE_URL/docs-html/v1/* and return the standard {ok, identity, data, ...} success envelope.

Document-reference contract

  • Canonical create has no document reference. Omit slug and provide html. The CLI generates idempotency_key; an explicit key is optional. A display name belongs in meta.title; it is metadata, not identity.
  • Save data.slug from the response. New documents always return data.doc_id and data.slug, with data.slug == data.doc_id, whether mounted or unmounted. Use data.slug for every later operation.
  • Legacy documents keep their old reference. For an old document, use its legacy slug wherever this skill says <doc-ref>.
  • No alias identity and no same-name republish. Creating again with the same meta.title creates a different document. To publish another version, supply the saved data.slug in the server's legacy-named slug field.
  • Do not infer a mode from mount_type, registered, status, or whether data.doc_id is non-empty. registered and status report operational state, not identity.

Query and JSON-body fields remain named slug for wire compatibility. Put the saved document reference in them. Path help displays <doc-ref>, and old legacy slugs are accepted. The CLI does not persist the reference.

Minimum rollout dependency: this contract requires the canonical-create server changes in octo-docs-backend#166 and octo-docs-html#33 to be merged and deployed before this CLI is released.

Auth & space

  • Authenticate with a stored bot profile (--profile / --bot-id) or OCTO_BOT_TOKEN; confirm the selected identity with octo-cli config show.
  • Do not pass --space. octo-doc resolves identity and space server-side.
  • Write operations require author/write capability. Reads need at least reader capability; backend failures are normalized into the CLI's {ok:false,error:{type,code,message,hint,detail}} envelope.

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.
