A guided seven-stage process for writing a long-form blog post, either from scratch or from an existing outline. It can use a project voice profile or inline tone guidance.

Use it to plan and write blog posts or articles, continue from a prepared outline, and shape the result to match a defined voice.

It breaks a large writing task into decisions about the idea, audience, purpose, context, and writing style before drafting.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00041	$0.00712
Opus 5.5	$0.00016	$0.00285
Sonnet 5.5	$0.00008	$0.00142
Haiku 4.5	$0.00004	$0.00071

Security

Grade A, and why

write-post scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

/guide:write-post — Blog Post Writing

Write a long-form blog post from scratch or from a pipeline-generated outline.

A 7-phase guided writing process that helps you write an authentic blog post in your voice.

Getting Started

This skill can start two ways:

From a pipeline outline — If a blog outline exists in content/drafts/ with needs_write_post: true in its frontmatter, offer to pick up from that outline and start from that context.
From scratch — If no outline exists or the user wants to start fresh, begin with the context phase. This preserves the current behavior of the original /write-post skill.

Voice Profile

Read the voice profile from config.yaml at voice.reference path. If the voice profile file is missing or unavailable, fall back to inline voice hints from the voice.tone config field. The skill should still work without a voice reference — use the tone keywords as style anchors.

The 7 Phases

Phase 1: Context

Gather context for the post:

What's the core idea or experience?
Who is the audience?
What should the reader feel or do after reading?
Read any existing blog outline (from pipeline or user-provided)

Phase 2: Scaffold

Create the post structure:

Build an outline following the emotional arc (hook → scene → mess → moment → reflection → soft landing)
Map each section to specific experiences, signals, or insights
Identify the emotional thread that ties everything together

Phase 3: Dictate

Write the first draft:

Encourage the user to speak/write freely — capture raw voice
Don't edit for polish yet — get the ideas down
Preserve authentic phrasing and emotional moments

Phase 4: Shape

Shape the raw draft into a structured post:

Apply the scaffold structure
Ensure smooth transitions between sections
Check that the emotional arc flows naturally
Maintain the user's authentic voice throughout

Phase 5: Iterate

Refine the draft:

Read aloud — does it sound like the user?
Check for jargon, corporate-speak, or generic language
Tighten sentences (target under 25 words each)
Ensure first-person voice is consistent
Get user feedback and incorporate changes
