What is weblog-from-webdav?

Instructions for building a live weblog from HTML or Markdown documents stored in a Virtuoso WebDAV collection. Virtuoso is a server platform, WebDAV is a way to manage remote files, and VSP pages are server-generated web pages.

Checking or bootstrapping the Virtuoso weblog engine, creating VSP templates and SQL deployment files, publishing WebDAV documents as posts, and verifying RSS or Atom feeds.

It provides a deployment path that keeps posts as ordinary files while making them available through a weblog, feeds, and search features.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00117	$0.02239
Opus 5	$0.00059	$0.01120

Security

Grade A, and why

weblog-from-webdav 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 10d ago.

The scan reads SKILL.md. This mod also ships 5 executable files (scripts/proppatch_categories.py, scripts/publish_with_metadata.py, scripts/set_pinned_post.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Weblog From WebDAV

Use this skill to turn a Virtuoso WebDAV folder into a live weblog whose posts remain ordinary files. The skill always starts by determining whether the Virtuoso-side weblog engine is already in place. If it is not, bootstrap it with isql; WebDAV is then used for the post-publication workflow.

Blocking Gate — WebDAV URL Means VSP/isql Weblog

When the user asks to generate a weblog from a WebDAV URL, a static HTML index is not a valid completion unless the user explicitly asks for a static-only page or preview. The default deliverable is either:

a live verified VSP weblog deployed on the target Virtuoso/WebDAV server, or
a complete deployable VSP/isql bundle: index.vsp, deploy-*.sql, optional route SQL, optional facet/category SQL when requested, README/run notes outside the skill package, and verification queries.

Before writing or claiming completion, read references/webdav-weblog-engine-gate.md and run scripts/validate_generated_weblog_bundle.py against the generated bundle. If deployment credentials are unavailable, stop at the deployable bundle and state that live deployment is blocked by missing authenticated isql/WebDAV access. Do not substitute a static HTML lens as the answer.

The skill supports two interaction modalities, each with plain credential and TLS/WebID variants:

isql engine mode: inspect or create the server-side weblog engine: VSP resource deployment, DAV path mapping assumptions, route/friendly URL setup, SQL helpers, full-text/search support, feed handling, metadata access, ACL/cache maintenance, and category staging. If the SQL listener is TLS-enabled, use isql with -X for the client PKCS#12 bundle, -T for the CA bundle, and -W for delegated WebID identity.
WebDAV post mode: publish posts and assets only, by copying HTML files, Markdown files, and associated asset folders into the configured DAV collection. WebDAV can also read or set custom resource properties when the engine already supports them. If acting as a software agent for a principal, pass the principal WebID via the On-Behalf-Of HTTP header.
OPAL tool mode: expose server-side weblog operations, such as post pinning, as Virtuoso stored procedures registered with OAI.DBA.REGISTER_CHAT_FUNCTION. Registered functions are available to OPAL/MCP-capable agents and are described through /chat/functions/openapi.yaml.

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.
