What is content-blog?

A writing guide for producing long blog posts, such as tutorials, opinion pieces, case studies, list articles, and detailed analyses.

It helps plan and write articles using a brand voice, a chosen format, supplied facts, links, key points, and a target length.

It removes the need to invent a structure and tone from scratch while helping avoid vague, generic writing.

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	$0.00045	$0.01449
Opus 5	$0.00023	$0.00724
Sonnet 5	$0.00009	$0.00290
Haiku 4.5	$0.00005	$0.00145

Security

Grade A, and why

content-blog 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 12d 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.

How it starts

The opening of the file, as written. The whole thing — 157 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Blog Post Generation

Before You Start

Check for brand voice: Read brand/VOICE.md if it exists. This file defines the brand's tone, vocabulary, formality level, and signature patterns. If it does not exist, use sensible defaults (clear, direct, conversational-professional) and suggest the user run the content-setup skill to configure their voice.
Determine the post type: Ask the user (or infer from their prompt) which format fits best:
- Tutorial -- step-by-step how-to content (templates/tutorial.md.template)
- Opinion -- thought-leadership or contrarian takes (templates/opinion.md.template)
- Case Study -- results-driven narrative (templates/case-study.md.template)
- Listicle -- list-format posts with substance (templates/listicle.md.template)
- Deep Dive -- long-form technical analysis (templates/deep-dive.md.template)
Gather inputs: Title or topic, target audience, key points the user wants covered, desired word count range, any links or data to reference.

Generation Flow

Follow these five stages. Do not skip any.

Stage 1: Brief

Confirm the following with the user (or extract from their prompt):

Topic and angle
Target audience and their existing knowledge level
Post type (tutorial, opinion, case-study, listicle, deep-dive)
Key points or arguments to include
Desired length (short: 800-1200 words, medium: 1200-2000 words, long: 2000-3500 words)
CTA or desired reader action

Stage 2: Outline

Produce a structured outline with:

Working title (can be refined later)
Hook concept (one sentence describing how the post opens)
Section headings with 2-3 bullet points each describing what goes in that section
Closing approach (CTA, insight, question, callback to opening)

Present the outline to the user for approval before drafting.

Stage 3: Draft

Write the full post following the approved outline. Apply:

The appropriate template from templates/
Brand voice from brand/VOICE.md (see voice-integration.md)
Anti-slop rules from anti-slop.md
Concrete examples, data, and specifics over abstract claims

What ships with it

7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
