write

A writing guide for marketing, social posts, product copy, launch messages, and replies in a specified personal voice. It uses a writing profile to choose an appropriate tone for the audience and situation.

In plain words
What is it for?
Use it to draft or revise marketing content, social updates, product and launch copy, and replies while matching the intended voice and register.
Why use it?
It helps keep related writing consistent and prevents the tone from drifting between professional copy, customer communication, and casual community posts.

Made for: Claude Code, Codex.

Or install emulo, the plugin that ships this one along with the rest of its 7 skills, 1 MCP server.

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

write 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 3d 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.

What it actually says

Emulo write

  1. Locate emulo.py two directories above this skill; fall back to ./emulo.py only for a direct repo checkout.
  2. Store the resolved absolute runtime path as EMULO_PY, then run python "$EMULO_PY" plugin profile-path --domain write.
  3. If it exits nonzero, give its exact recovery or targeted-deepen instruction and stop loading personal context.
  4. Read every returned path completely. The first is the core working profile; the second is the writing profile. Apply both.
  5. Pick the register from context; never ask. A writing profile with register sections (## Voice laws, ## Casual register, ## Professional register) loads voice laws always, plus exactly one register:
    • An explicit audience statement from the user ("for my boss", "make it formal") always wins.
    • Otherwise infer from what is in the task: a pasted thread with a manager, client, or customer, a formal email, documentation, or official product copy selects professional; a community reply, social post, chat banter, or a builder-to-builder thread selects casual; a pasted conversation selects the register matching that thread's own audience and tone.
    • State the pick in one short line ("using professional register") so it is correctable, then write; never block on register confirmation.
    • If the picked register has no section in the profile, load the voice laws only and never substitute the other register; say so in the same line ("professional register not mined yet, using voice laws only") and suggest run emulo and deepen write to mine it.
    • A flat profile without register sections applies in full, unchanged.
  6. Never imitate a generic voice when the writing domain is inactive.

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.
