Validate an SGLang configuration for NVIDIA DGX Spark (GB10/SM121A). Pure pattern-matching against known failure modes documented in the Sovereign AI Blog. No inference, no external calls. Returns critical issues, non-fatal warnings, and a recommended baseline config. All parameters are optional; supply only what you have. With no inputs you get the recommended config and a 'unknown' verdict.
Hardware description (e.g. 'GB10', 'DGX Spark', 'SM121A'). Empty = skip GB10-specific rules.
Docker image tag in use (e.g. 'lmsysorg/sglang:latest', 'lmsysorg/sglang:v0.4.0'). Empty = skip.
SGLang --mem-fraction-static value (e.g. 0.88). 0.0 = skip this check.
Paste error log output here for pattern matching against known failure modes.
SGLang --attention-backend value (e.g. 'flashinfer', 'triton'). Empty string = skip this check.
SGLang --cuda-graph-max-bs value. 0 = skip this check.

}Retrieve the full content of a blog article by its slug. Returns the article body (Markdown) plus metadata. If the slug does not match any article, returns an Article with `error='article_not_found'` and other fields at their defaults.
| Argument | Type | Description |
|---|---|---|
| slug* | string | Article slug as returned by search_blog (e.g. 'setup-llm-inference-setup'). Lower-case, hyphenated. |

}List all blog articles. No TF-IDF computation — pure database listing. Use to browse the full corpus, paginate through articles, or filter by tag. For full-text semantic search use search_blog instead.
| Argument | Type | Description |
|---|---|---|
| tag | any | Optional tag filter (e.g. 'setup', 'fixes', 'strategy'). Only articles with this tag are considered. Use list_tags to discover available tags. |
| sort | string | Result ordering. 'date_desc' newest first (default). 'date_asc' oldest first. 'title_asc' alphabetical. 'quality_desc' best quality first. |
| limit | integer | Number of results (1-50) |
| offset | integer | Pagination offset (0-based) |

}List all topic tags used across the Sovereign AI Blog corpus, with article counts. Use this to browse the topic space before calling search_blog with a tag filter.
| Argument | Type | Description |
|---|---|---|
| sort | string | Result ordering. 'count_desc' lists most-used tags first (default). 'alpha' sorts alphabetically. |

}Search the Sovereign AI Blog for articles matching a natural language query, optionally filtered by tag and sorted by relevance or date. Behaviour matrix: - query='', sort=* -> list newest-first, optionally tag-filtered - query!='', sort=relevance -> TF-IDF ranked, optionally tag-filtered - query!='', sort=date_desc -> TF-IDF filtered (score > 0.001), then sorted by date Pure read-only, deterministic for a given KB snapshot.
| Argument | Type | Description |
|---|---|---|
| n | integer | Maximum number of results to return |
| tag | any | Optional tag filter (e.g. 'setup', 'fixes', 'strategy'). Only articles with this tag are considered. Use list_tags to discover available tags. |
| sort | string | Result ordering. 'relevance' uses TF-IDF score (default for non-empty query). 'date_desc' sorts newest first (default behaviour when query is empty). When query is empty, 'relevance' is treated as 'date_desc'. |
| query | string | Natural language search query (e.g. 'flashinfer OOM on GB10'). Multi-word queries are tokenized and TF-IDF ranked. Pass empty string to list articles without ranking by relevance. |
