improvement(blocks): extract model config subBlocks into shared utils

* feat(models): updated model configs, updated anthropic provider to propagate errors back to user if any

* moved max tokens to advanced

* updated model configs and testesd

* removed default in max config for output tokens

* moved more stuff to advanced mode in the agent block

* stronger typing

* move api key under model, update mistral and groq

* update openrouter, fixed serializer to allow ollama/vllm models without api key

* removed ollama handling

 This works across all supported LLM providers — the `load_skill` tool uses standard tool-calling, so no provider-specific configuration is needed.
 
-## Tips
+## Common Use Cases
 
-- **Keep descriptions actionable** — Instead of "Helps with SQL", write "Write optimized SQL queries for PostgreSQL, MySQL, and SQLite, including index recommendations and query plan analysis"
+Skills are most valuable when agents need specialized knowledge or multi-step workflows:
+
+**Domain Expertise**
+- `api-integration-expert` — Best practices for calling specific APIs (authentication, rate limiting, error handling)
+- `data-transformation` — ETL patterns, data cleaning, and validation rules
+- `code-reviewer` — Code review guidelines specific to your team's standards
+
+**Workflow Templates**
+- `bug-investigation` — Step-by-step debugging methodology (reproduce → isolate → test → fix)
+- `feature-implementation` — Development workflow from requirements to deployment
+- `document-generator` — Templates and formatting rules for technical documentation
+
+**Company-Specific Knowledge**
+- `our-architecture` — System architecture diagrams, service dependencies, and deployment processes
+- `style-guide` — Brand guidelines, writing tone, UI/UX patterns
+- `customer-onboarding` — Standard procedures and common customer questions
+
+**When to use skills vs. agent instructions:**
+- Use **skills** for knowledge that applies across multiple workflows or changes frequently
+- Use **agent instructions** for task-specific context that's unique to a single agent
+
+## Best Practices
+
+**Writing Effective Descriptions**
+- **Be specific and keyword-rich** — Instead of "Helps with SQL", write "Write optimized SQL queries for PostgreSQL, MySQL, and SQLite, including index recommendations and query plan analysis"
+- **Include activation triggers** — Mention specific words or phrases that should prompt the skill (e.g., "Use when the user mentions PDFs, forms, or document extraction")
+- **Keep it under 200 words** — Agents scan descriptions quickly; make every word count
+
+**Skill Scope and Organization**
 - **One skill per domain** — A focused `sql-expert` skill works better than a broad `database-everything` skill
-- **Use markdown structure** — Headers, lists, and code blocks help the agent parse and follow instructions
-- **Test iteratively** — Run your workflow and check if the agent activates the skill when expected
+- **Limit to 5-10 skills per agent** — More skills = more decision overhead; start small and add as needed
+- **Split large skills** — If a skill exceeds 500 lines, break it into focused sub-skills
+
+**Content Structure**
+- **Use markdown formatting** — Headers, lists, and code blocks help agents parse and follow instructions
+- **Provide examples** — Show input/output pairs so agents understand expected behavior
+- **Be explicit about edge cases** — Don't assume agents will infer special handling
+
+**Testing and Iteration**
+- **Test activation** — Run your workflow and verify the agent loads the skill when expected
+- **Check for false positives** — Make sure skills aren't activating when they shouldn't
+- **Refine descriptions** — If a skill isn't loading when needed, add more keywords to the description
