recommend_productsRecommend catalog products for a need described in plain language.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it Recommend catalog products for a need described in plain language. FREE. Typical input {"need": "help answering customer support emails"} returns {"need": ..., "recommendations": [{"slug": ..., "name": ..., "why": ..., "area": ..., "try_free": "<free skill name>"}], "next": "..."}. Use when the caller describes a problem instead of naming a product; ranking is by fit to the described need. Not for exact keyword or slug lookups (search_catalog). Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"}. Every call is read-only and idempotent, so after correcting the input it is always safe to retry.

get_free_skillLoad a product's free gateway skill with its complete instructions.No findings
Why it is in this group
- The name "get_free_skill" says "get": a word for reading.
Description, as the server wrote it Load a product's free gateway skill with its complete instructions. FREE. Typical input {"slug": "inbox-zero-assistant"} returns {"slug": ..., "skill": "<skill name>", "instructions": "<full skill text>"}. Returns exactly one skill - the product's free gateway skill - chosen automatically from the slug, with no plan required. Use when the caller wants usable instructions immediately. Not for the product's other skills: those are named and need get_full_skill with a skill_name, which requires a paid plan. Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"} (for example {"error": "unknown slug '<value>'"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry.
Annotations the server declares
- title: Get Free Skill
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
get_full_kitLoad a themed kit and every member product in full.No findings
Why it is in this group
- The name "get_full_kit" says "get": a word for reading.
Description, as the server wrote it Load a themed kit and every member product in full. PREMIUM (paid plan). Typical input {"slug": "founder-kit"} returns {"slug": ..., "name": ..., "products": [{"slug": ..., "name": ..., "persona": ..., "skills": [...]}, ...]}. Returns every member product of one bundle in full, so the payload is large. Use only after list_kits has confirmed the kit slug. Not for a single product (get_full_product). Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"} (for example {"error": "unknown kit '<value>'"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry.
Annotations the server declares
- title: Get Full Kit
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
get_full_personaLoad a product's complete persona definition.No findings
Why it is in this group
- The name "get_full_persona" says "get": a word for reading.
Description, as the server wrote it Load a product's complete persona definition. PREMIUM (paid plan). Typical input {"slug": "inbox-zero-assistant"} returns {"slug": ..., "persona": "<full persona text>"}. Returns the persona text alone, with no skill bodies. Use when the caller needs the product's voice and operating rules only. Not when skills are also wanted - get_full_product returns persona and every skill in one call. Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"} (for example {"error": "unknown slug '<value>'"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry.

get_full_productLoad one product in full: persona plus every skill's instructions.No findings
Why it is in this group
- The name "get_full_product" says "get": a word for reading.
Description, as the server wrote it Load one product in full: persona plus every skill's instructions. PREMIUM (paid plan). Typical input {"slug": "inbox-zero-assistant"} returns {"slug": ..., "name": ..., "persona": ..., "skills": [{"name": ..., "instructions": ...}], "free_skill": {...}}. Returns persona plus every skill for one product. Use when the caller wants the whole product. Not for a single skill (get_full_skill) and not for a bundle of products (get_full_kit). Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"} (for example {"error": "unknown slug '<value>'"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry.
Annotations the server declares

get_full_skillLoad one paid skill's complete instructions from a product.No findings
Why it is in this group
- The name "get_full_skill" says "get": a word for reading.
Description, as the server wrote it Load one paid skill's complete instructions from a product. PREMIUM (paid plan). Typical input {"slug": "inbox-zero-assistant", "skill_name": "Deep Triage"} returns {"slug": ..., "skill": ..., "instructions": "<full skill text>"}. Returns one named skill, selected by skill_name. Use after preview_product has shown the skill list and the caller wants one specific paid skill. Not for the free gateway skill, which get_free_skill returns with no plan, and not for every skill at once (get_full_product). Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"} (for example {"error": "unknown slug '<value>'"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry.

list_kitsList the 12 themed kits with pricing and member products.No findings
Why it is in this group
- The name "list_kits" says "list": a word for reading.
Description, as the server wrote it List the 12 themed kits with pricing and member products. FREE. Takes no arguments. Returns a list of kit objects, each {"slug": ..., "name": ..., "price_usd": N, "tagline": ..., "members": ["product-slug", ...], "availability": ...}. Use a kit's slug with get_full_kit (premium). Kits are not sold standalone on any marketplace: price_usd is the bundle's reference value, and All-Access is how a caller actually unlocks one. Use when the caller asks about bundles or bundle pricing. Not for individual products (search_catalog) and not for a kit's full contents (get_full_kit). Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"}. Every call is read-only and idempotent, so after correcting the input it is always safe to retry.
Annotations the server declares
- title: List Kits
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
preview_productPreview one product: metadata, persona teaser, and paid-skill teasers.No findings
Why it is in this group
- The name "preview_product" says "preview": a word for reading.
Description, as the server wrote it Preview one product: metadata, persona teaser, and paid-skill teasers. FREE. Typical input {"slug": "inbox-zero-assistant"} returns {"slug": ..., "name": ..., "tagline": ..., "persona_preview": ..., "skills": [{"name": ..., "preview": ...}], "free_skill": ..., "note": ...}. Returns teasers only, never full text. Use to judge a product before committing. Not for the complete persona or skill bodies (get_full_persona, get_full_product), and not when the caller wants instructions they can act on now (get_free_skill). Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"} (for example {"error": "unknown slug '<value>'"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry.
Annotations the server declares
- title: Preview Product
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
search_catalogSearch all 138 catalog products by keyword and/or focus area.No findings
Why it is in this group
- The name "search_catalog" says "search": a word for reading.
Description, as the server wrote it Search all 138 catalog products by keyword and/or focus area. FREE. Typical input {"query": "email inbox", "limit": 5} returns a ranked list of product objects [{"slug": ..., "name": ..., "area": ..., "segment": ..., "tagline": ...}]. An empty query with an area set browses that area. Use when the caller names a keyword, product, or focus area to look up. Not for bundles (list_kits) and not for plain-language problem statements, which recommend_products ranks by fit rather than keyword match. Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"}. Every call is read-only and idempotent, so after correcting the input it is always safe to retry.
Annotations the server declares
- title: Search Catalog
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
upgrade_infoExplain how to unlock full personas, paid skills, and kits.No findings
Why it is in this group
- The description's first verb is "explain": a word for reading.
Description, as the server wrote it Explain how to unlock full personas, paid skills, and kits. FREE. Takes no arguments. Returns {"message": ..., "how": ..., "free_tier": ...} describing the upgrade path and what stays free. Use when a premium tool has been refused or the caller asks what a plan covers. Not for per-bundle or per-product pricing (list_kits, preview_product). Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"}. Every call is read-only and idempotent, so after correcting the input it is always safe to retry.
Annotations the server declares
- title: Upgrade Info
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
