Brand Voice & Quality
Keep generated and rewritten content on-brand and readable — list saved voice profiles, apply one to a generation or rewrite, and run a de-slop pass that strips LLM clichés and filler before it ships.
Voice-profile creation is web-only. Building a new voice profile (from a writing sample, imported social posts, or a deep voice for a key author) happens in the PostKing dashboard's voice-profiles page — there is no MCP tool to create, extract, or import a voice. This skill covers what comes after: listing an existing profile and applying it.
When to Use
Use this skill when a user wants existing content rewritten in a specific saved brand voice, wants a voiceId to pass into another skill's generation call, or wants a de-slop pass to strip LLM clichés and filler before it ships.
When NOT to Use
Not for creating a new voice profile — that's web-only, done in the PostKing dashboard. Not for generating original content from scratch — that's postking-social/postking, postking-seo, postking-storylines, or postking-reddit, each of which accepts a voiceId from this skill as a parameter. Not for presenting AI-generated content as human-written where a platform, client, publisher, or law expects disclosure.
Minimal tool subset
This skill needs only these 5 tools out of PostKing's 200+:
list_voices— list saved voice profiles with their IDs.rewrite_with_voice— rewrite arbitrary text in a specific saved voice.rewrite_text— general rewrite, optionally applying a voice profile.humanize_text— de-slop pass: replaces stock LLM phrasing (filler, hedges, canned transitions) with plainer, more specific prose.check_ai_content— diagnostic: flags passages that read as generic or templated, so a human can revise them.
Prerequisites
- Authenticated with credits — see the
postking-getting-startedskill. - A brand already onboarded — see the
postking-getting-startedskill.
Voices get applied downstream in the postking skill (posts, blogs, landing pages, repurposing), the postking-seo skill (article writing), and the postking-storylines skill (campaign drafts).
Procedure
"Rewrite this in our brand voice and cut the AI clichés."
- Build a voice (dashboard only, one-time). If no voice profile exists yet, tell the user to build one in the PostKing dashboard's voice-profiles page (from a writing sample, imported social posts, or a deep author voice) — there is no MCP tool for this step.
- List voices.
list_voices({})— get theprofileIdfor the voice to use. - Apply at generation time (preferred). Pass that voice id as the
voice/voiceProfileIdparam directly ongenerate_post,generate_blog_post,generate_landing_page,repurpose_content, orreddit_rewrite— no separate rewrite pass needed. These tools live in thepostking,postking-seo,postking-storylines, andpostking-redditskills. - Apply to existing text.
rewrite_with_voice({ profileId, text, platform })— orrewrite_text({ text, voice: profileId, platform })for a lighter-touch pass. - De-slop.
humanize_text({ text, platform })— replaces stock LLM phrasing and clichés with plainer, more specific prose. Run this after voice rewriting, right before the text ships. - Spot-check (optional).
check_ai_content({ text })— flags passages that still read as generic or templated. Treat it as a diagnostic pointing at weak writing for a human to revise, not a number to optimise: do not loophumanize_textagainst the score.
CLI fast path
pking voice list lists saved voices (equivalent to list_voices). Beyond that, the MCP path above is primary — do not assume additional pking flags exist for rewrite/humanize without checking pking --help first.
Expected Output
Content rewritten in a chosen brand voice, with stock LLM phrasing and filler replaced by plainer, more specific prose.
Disclosure
These tools improve writing quality. They do not change the fact that the content was AI-generated, and must not be used to conceal AI authorship where a platform, client, publisher, or law requires it to be disclosed.
Pitfalls
list_voicesreturns empty — no voice profile exists yet; build one in the PostKing dashboard (creation is web-only, not available via MCP).INSUFFICIENT_CREDITS— surface thecheckoutUrlfrom the error envelope and stop, or hand off to thepostking-getting-startedskill's billing section (billing_list_packs→billing_topup).RATE_LIMITED— back off using theretryAftervalue from the error envelope before retrying.UNAUTHORIZED— re-run the login flow described in thepostking-getting-startedskill.
Verification
list_voices({})should return successfully; a non-empty result confirms at least one profile exists to reference.- After
humanize_text, the result should come back successfully and read as plainer and more specific than the original — judge the copy itself, not a detector score.
