What it does

Post Writing is an agent skill from benjamincrozat/blog-v5. Draft and revise publication-ready Markdown blog posts with reader-first writing, current primary sources, tested examples, reproducible benchmarks for quantitative claims, visually inspected screenshots, evidence-led SEO experiments, and clear editorial judgment. Use for new posts, search-focused refreshes, tutorials, troubleshooting guides, comparisons, reviews, performance claims, new libraries, major framework features, version-sensitive pages, and timely news in resources/markdown/posts.

Its SKILL.md is about 2.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files (for example `agents/openai.yaml`, `references/evidence-standard.md` and `references/ranking-reality.md`).

It sits in Writing & Content, covering Blog and article writing and Markdown. It works with Laravel and Tailwind CSS. The repository describes itself as: Source code for Benjamin Crozat's blog.

Workflow steps

10 steps, taken from the first numbered list in SKILL.md.

  1. Decide whether the task is a new post, a refresh, or a small copy edit. Define the reader outcome, search intent, decision, business role…
  2. For ranking work, read the ranking reality and refresh standards. Inspect current demand and live search results, read the whole article…
  3. Read the evidence standard and map every important claim to a source, test, measurement, inspected visual, or explicit judgment.
  4. Gather current primary sources and build the runnable fixture, reproduction, benchmark, comparison, or visual proof before drafting around…
  5. Choose the simplest accurate title and outline. Make the main query and promise clear early. Keep the existing slug and winning angle…
  6. Draft for clarity and usefulness. Put each source or observed result next to the claim it supports.
  7. Add or replace visuals only after inspecting the actual assets. Make the final image readable in the rendered article, not only at full…
  8. Strengthen useful incoming and outgoing internal links, then add direct links to external primary evidence. Remove repeated FAQs, filler…
  9. Rerun the exact published examples, verify factual links, review benchmark limits, inspect every final image, and check the rendered…
  10. Hand the stable article to file-first-posts for image upload, timestamps, sync, publishing checks, and final repository validation.

What it can do on your machine

Read from SKILL.md and the folder at commit 68aaa9c. 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.

    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

Post Writing loads about 2.3k tokens when it runs, and up to ~9.3k if it reads all its reference files. Until then it costs about 128 tokens; SKILL.md has 1,257 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~128
When it runs · the whole SKILL.md, loaded when a task matches
~2.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~9.3k

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 1,257 words (~2,311 tokens).

“Final gate: prove the central promise, add a clear original contribution, state important limits, preserve valid front matter and stable IDs, and leave no untested claim disguised as first-hand experience.”
