stalux_list_posts

Paginated list of all published posts, returning title, permanent link (abbrlink), date, categories, tags, description and post page URL. Use it to browse the whole blog or find a post's abbrlink; it does not return body content — use stalux_get_post for one post's metadata, or stalux_read_post for the full body. Prefer pageSize 50 to fetch everything in one call; out-of-range pages clamp to the last page (clamped flag).Answers a question. Declared read only.

warningSchema quality

3.4 / 4

1 of 7 tool schemas are harder for an agent to use than they need to be: stalux_list_posts declares no required list, so an agent cannot tell which parameters are mandatory.

stalux_list_posts: declares no required list, so an agent cannot tell which parameters are mandatory

fix

{
  name: "stalux_list_posts",
  inputSchema: {
    type: "object",
    properties: {
      query: { type: "string", description: "What to search for" }

  }
}

warningNaming quality

1 / 2

Tool naming makes selection harder than it needs to be: 7 names do not start with a verb (stalux_list_posts).

fix

{ name: "stalux_list_posts" /* short, unique, verb-based */ }

warningHuman parity

0 / 8

7 of 7 tools run through the JavaScript API with no visible counterpart, so the person co-browsing cannot see what the agent is offered. Declarative forms (or at least a title annotation) close the gap.

stalux_list_posts, stalux_get_post, stalux_current_post, stalux_random_post, stalux_search_posts

Findings

WebMCP use

75 / 100 · weight 50

passTools registered

4 / 4

7 tools registered across 1 page.

failReal-browser eligible

0 / 8

The page's code registers these tools, but a real visitor's browser does not get them yet: WebMCP needs a native modelContext or a current origin trial token, and this page has neither.

passRegistration timing

4 / 4

Every measured tool registered within 855.2999999523163ms of navigation.

toolstalux_site_info

passCanonical entry point

4 / 4

All 7 tools register on the canonical document.modelContext entry point.

passSchema validity

5 / 5

All 7 tools declare a structurally valid object input schema.

warningSchema quality

3.4 / 4

1 of 7 tool schemas are harder for an agent to use than they need to be: stalux_list_posts declares no required list, so an agent cannot tell which parameters are mandatory.

stalux_list_posts: declares no required list, so an agent cannot tell which parameters are mandatory

fix

{
  name: "stalux_list_posts",
  inputSchema: {
    type: "object",
    properties: {
      query: { type: "string", description: "What to search for" }
    },
    required: ["query"]
  }
}

passStub detection

5 / 5

All 7 tools declare an execute handler.

passAnnotations present

4 / 4

All 7 tools declare a readOnlyHint, so an agent knows which calls change state.

passAnnotation mismatch

3 / 3

No tool claims to be read-only while its name says it writes (7 declared hints checked).

warningUntrusted content hint

0 / 2

1 of 1 tools look like they return text written by other people but declare no untrustedContentHint, so an agent will treat the response as the site speaking.

toolstalux_current_post

stalux_current_post: post, user

fix

{ name: "stalux_current_post", annotations: { untrustedContentHint: true } }

passRegistration errors

2 / 2

No tool registration threw during the capture.

warningToolchange coherence

1 / 2

7 tools were registered but the page never dispatched a toolchange event, so an agent subscribed to registry updates never learns they exist.

fix

document.modelContext.dispatchEvent(new Event("toolchange"));

not applicableInjection surface

0 / 3

The injection-surface model hop returned no usable result, so tool contracts were not reviewed for injection surface.

warningNaming quality

Tool naming makes selection harder than it needs to be: 7 names do not start with a verb (stalux_list_posts).

fix

{ name: "stalux_list_posts" /* short, unique, verb-based */ }

not applicableDescription quality

0 / 6

The description-quality model hop returned no usable result, so descriptions were not rated.

not applicableTool selection

0 / 14

The tool-selection model hop returned no usable result.

not applicableCoverage vs. site type

0 / 8

This tool set does not place the site in a category with a known expected tool shape, so there is no coverage baseline to score it against.
