What it can do on your machine

Read from SKILL.md and the folder at commit ff30cb3. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown and bash).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Cashclaw Content Writer loads about 1.9k tokens when it runs. Until then it costs about 50 tokens; SKILL.md has 659 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~50
When it runs · the whole SKILL.md, loaded when a task matches
~1.9k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Blog Post Workflow

Step 1: Brief Analysis

When you receive a content request, extract or ask for:

  1. Topic / Title idea - What should the post be about?
  2. Target keyword(s) - Primary and secondary keywords.
  3. Audience - Who is reading this? (e.g., SMB owners, developers, marketers)
  4. Tone - Professional, casual, technical, friendly, authoritative.
  5. CTA - What should the reader do after reading? (sign up, buy, contact, share)
  6. Word count - 500 or 1500 (or custom).
  7. References - Any sources, competitors, or inspiration links.

If any of these are missing, ask the client before writing.

Step 2: Keyword Research Outline

Before writing, create a structured outline:

markdown
## Content Outline

**Title:** {SEO-optimized title with primary keyword}
**Primary Keyword:** {keyword} (target density: 1-2%)
**Secondary Keywords:** {kw1}, {kw2}
**Search Intent:** {informational | transactional | navigational}
**Target Word Count:** {count}

### Structure
1. Introduction (hook + problem statement + what they will learn)
2. {H2 Section 1} - {keyword angle}
3. {H2 Section 2} - {keyword angle}
4. {H2 Section 3} - {keyword angle}
5. {H2 Section 4 - optional} - {keyword angle}
6. Conclusion (summary + CTA)

Share this outline with the client for approval before writing the full post.

Step 3: Writing

Follow these rules for every blog post:

SEO Rules:

  • Primary keyword in: title, H1, first 100 words, one H2, meta description, URL slug.
  • Secondary keywords distributed naturally through body text.
  • Keyword density: 1-2% for primary, 0.5-1% for secondary.
  • Internal links: Suggest 2-3 relevant internal link placements.
  • External links: Include 1-2 authoritative external sources.
  • Meta description: 150-160 characters, includes primary keyword, compelling CTA.

Readability Rules:

  • Sentences: Max 20 words average. Mix short and long.
  • Paragraphs: Max 3-4 sentences. Use whitespace generously.
  • Use bullet points and numbered lists for scanability.
  • Include at least one image suggestion per 500 words (describe what to use).
  • Use transition words: "However," "Additionally," "For example," "Here is why."
  • Target Flesch Reading Ease score: 60+ (8th-grade level).

Structure Rules:

  • Hook in the first sentence. No throat-clearing introductions.
  • Every H2 section should be self-contained and valuable on its own.
  • End every section with a bridge to the next.
  • Conclusion must restate the key takeaway and include a clear CTA.
Step 4: SEO Metadata

Provide these with every blog post:

markdown
---
title: "{SEO title, 50-60 chars}"
description: "{Meta description, 150-160 chars}"
slug: "{url-friendly-slug-with-keyword}"
keywords: ["{primary}", "{secondary1}", "{secondary2}"]
author: "{client name or brand}"
date: "{ISO8601}"
---
Step 5: Quality Checklist
