analyze_writing
Analyze Writing
Analyze a draft for readability, passive voice, cliches, and hedging. FREE.
Also measures sentence variety and keyword density, and produces a
prioritized fix list. Typical input {"text": "<your draft>"} returns
{"readability_grade": 9.2, "passive_voice_count": N, "cliches_found":
[...], "hedging_words": [...], "sentence_count": N,
"avg_words_per_sentence": N, "top_repeated_words": [...],
"priority_fixes": ["..."]}.
Use on body prose to find readability and style problems. Not for ranking
titles (headline_analyzer) and not for platform limits
(social_length_check). 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": "empty text"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry.

get_free_skill
Get Free Skill
Load a product's free gateway skill with its complete instructions. FREE.
Typical input {"slug": "brand-voice"} returns {"slug": "brand-voice",
"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>'. Use list_products."}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry.

get_full_product
Get Full Product
Load one product in full: its persona plus every paid skill. PREMIUM (license).
Typical input {"slug": "brand-voice"} returns {"slug": ..., "name": ...,
"persona": "<persona text>", "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 free look, which list_products and get_free_skill provide with no
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.

get_full_skill
Get Full Skill
Load one paid skill's complete instructions from a product. PREMIUM (license).
Typical input {"slug": "brand-voice", "skill_name": "Voice Audit"}
returns {"slug": ..., "skill": ..., "instructions": "<full skill text>"}.
Returns one named skill, selected by skill_name. Use when 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>'"}).

headline_analyzer
Headline Analyzer
Score and rank up to 20 headlines, best first. FREE.
Scores 0-100 on length, power/emotion words, numbers, structure, and
clarity. Typical input {"headlines": ["7 Mistakes New Writers Make",
"On Writing"]} returns {"ranked": [{"headline": ..., "score": 85,
"notes": ["good length", "contains number"]}, ...]}.
Use when several title options need ranking. Not for email subject lines,
which the outbound server's subject_line_scorer judges against
deliverability signals, and not for body prose (analyze_writing). 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.

list_products
List Products
List every product in the Creator Studio line with its included skills. FREE.
Takes no arguments. Returns a list of 20 product objects, each
{"slug": "brand-voice", "name": ..., "tagline": ..., "skills": ["Skill
A", ...], "free_skill": "Gateway Skill Name"}. Use the returned slug
values with get_free_skill, get_full_product, or get_full_skill.
Returns metadata only - no persona text and no skill instructions. Use
when the caller wants to see what this server covers. Not for keyword
search across the whole 138-product catalog, which the catalog server's
search_catalog does, and not for instructions the caller can act on
(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>"}. Every call is read-only and idempotent, so after correcting the input it is always safe to retry.

reading_time
Reading Time
Estimate reading and speaking time plus basic content stats. FREE.
Typical input {"text": "<your article>"} returns {"words": 1200,
"reading_minutes": 5.2, "speaking_minutes": 8.6, "paragraphs": 14,
"fit": "newsletter/blog"}.
Use when length and pacing are the question. Not for writing quality or
grade level (analyze_writing). 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.

social_length_check
Social Length Check
Check a post against every major platform's length limit at once. FREE.
Covers X, LinkedIn posts and headlines, Instagram captions, Threads,
YouTube titles, and meta descriptions. Typical input {"text": "<post>"}
returns {"chars": N, "platforms": {"x_post": {"limit": 280, "fits":
true, "over_by": 0}, ...}}.
Use before posting, to catch truncation. Not for readability
(analyze_writing) and not for reading duration (reading_time). 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.
