- No malware found by supply-chain analysis.Pass
- Only part of the dependency tree could be resolved (95 of 99), so this covers what we could see, not the whole tree.Partial
- No install/post-install scripts declared.Pass
- Only part of the dependency tree could be resolved (95 of 99), so this covers what we could see, not the whole tree. View diagnostics → Partial

Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified

The dependency tree was only partially resolved, so these counts may be incomplete.
The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability.
check_post ~157
Check a social post against one platform's real character limit and report whether it fits. Returns the counted length, the limit, and what drove the count (URLs billed at a fixed width, non-Latin characters billed double, emoji sequences collapsed to one grapheme). Use this before publishing anything with a hard limit — the counting rules are per-platform and are not text.length.
| Name | Type | Req | Description |
|---|---|---|---|
| platform | string | yes | Which platform's rules to apply: x, x_premium, bluesky, linkedin, threads, mastodon, discord. |
| text | string | yes | The post text, exactly as it will be published. Leading and trailing whitespace is trimmed, as the platforms do. `[URL]`-style placeholders are priced as a real link. |
No output schema declared.
No examples provided.
check_post_all ~119
Check one post against every platform at once and get a row per platform: counted length, limit, and whether it fits. Use this when deciding where a draft can go as-is. The per-platform arithmetic is included only for the platforms it fails, to keep the response small — call check_post for a single platform's full breakdown.
| Name | Type | Req | Description |
|---|---|---|---|
| text | string | yes | The post text, exactly as it will be published. Leading and trailing whitespace is trimmed, as the platforms do. `[URL]`-style placeholders are priced as a real link. |
No output schema declared.
No examples provided.
platform_limits ~78
List the platforms this server knows, with each one's limit, the unit it is measured in, why that unit is not a plain character count, and the source the number came from. Use it to explain a result or to see what is covered.
| Name | Type | Req | Description |
|---|---|---|---|
| platform | string | — | Limit the response to one platform. Omit for all of them. |
No output schema declared.
No examples provided.
