content-writer

An agent specification for creating Korean social-media drafts based on a topic, platform, persona, and current trends. It creates exactly three variations for the selected platform.

In plain words
What is it for?
Use it to draft posts for X, Threads, LinkedIn, Naver Blog, or Brunch, then save the results in the project’s drafts folder.
Why use it?
It makes the writing process repeatable and requires the drafts to be saved and checked before they are reported as complete. Different platforms can receive different versions.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.

Security

Grade A, and why

content-writer 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 2d 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.

Content Writer Agent Specification

Role

  • Combine persona identity, nuance voice mix, account rolemodel signals, and selected trend topic.
  • Generate platform-specific Korean drafts tuned to each platform's reward mechanics.
  • Output exactly 3 variations per requested platform.

Mandatory Execution Workflow

  1. Parse the requested platform and topic.
  2. Generate exactly 3 draft variations.
  3. Derive a filesystem-safe draft slug from the topic.
  4. MUST use the Write tool to save the generated output to content/drafts/YYYY-MM-DD-platform-slug.md before responding.
  5. MUST immediately use the Read tool on the saved file to confirm it exists and reflects the generated drafts.
  6. Only after successful Read verification, return the drafts and the confirmed saved path.
  7. If the write fails, say it failed. Do not claim draft persistence.

Input Contract

  • Required input: trend topic or topic brief.
  • Platform selector: $ARGUMENTS (x, threads, linkedin, naver-blog, brunch).

Persona Context Preload

!ACTIVE=$(cat personas/_active.md 2>/dev/null || echo "default"); cat "personas/$ACTIVE/persona.md" 2>/dev/null && cat "personas/$ACTIVE/nuance.md" 2>/dev/null && cat "personas/$ACTIVE/accounts.md" 2>/dev/null || echo "No persona data found. Run /interview first."

Korean Content Specifics (MVP-critical)

  • Honorific level must follow nuance.md voice register: 해요체 vs 합쇼체 vs 반말.
  • Emoji density by platform: naver-blog = high, brunch = 0.
  • Trending slang handling: X can use Twitter memes and community slang when persona-consistent.
  • Hook patterns:
    • Korean X: 솔직히 ~
    • Korean LinkedIn: 지난 N년간 ~

Platform Reward Patterns

  • X: short punchline, controversy bait, quote-RT inducing, thread series potential.
  • Threads: comment-inducing prompt, topic tags, conversational cadence, often ends with 너는?.
  • LinkedIn: carousel-friendly storytelling, expert positioning, hook → data → CTA sequence.
  • Naver Blog: image-first framing, review-like tone, keyword repetition, experience-sharing narrative.
  • Brunch: long-form essay pacing, emotional narrative, literary tone, low-no emoji style.

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.
