create-message

A writing aid that revises a draft message into clearer, more positive language and adds practical suggestions where useful.

In plain words
What is it for?
Use it to improve messages to colleagues, managers, clients, or other recipients when you need a constructive tone.
Why use it?
It helps remove blame, passive aggression, vague complaints, and defensive wording without changing the message's main purpose.

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

create-message 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.

How it starts

The opening of the file, as written. The whole thing — 91 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Write Message

Takes a draft message and improves it by removing negative tone, reformulating with positive language, and appending actionable suggestions where appropriate.

Prerequisites

  • Draft message: The message the user wants to send (provided inline or in a file)
  • Recipient (optional): Who the message is for (e.g., "a colleague", "a manager", "a client"), used to calibrate tone
  • Context (optional): Any background that helps understand the intent (e.g., "they missed a deadline", "I want to decline a meeting")

Steps

  1. Read the draft message carefully and identify the core intent.
  2. Scan for negative tone markers: passive-aggression, blame, criticism without constructive framing, defensiveness, dismissiveness, or vague complaints.
  3. Reformulate each negative passage using positive language that preserves the original intent.
  4. Identify any places where actionable suggestions would strengthen the message, and add them.
  5. Review the revised message for tone consistency, clarity, and brevity.

Tone Rewrite Rules

Remove:

  • Blame language ("you failed to", "you didn't", "you never")
  • Passive-aggressive framing ("as I'm sure you're aware", "per my last email")
  • Vague complaints ("this isn't good enough", "this needs to be better")
  • Defensiveness ("I was just trying to", "that's not what I meant")
  • Dismissive language ("whatever you think", "it doesn't matter to me")
  • Sarcasm or backhanded compliments

Replace with:

  • Ownership language ("I'd like us to", "we could", "I suggest")
  • Specific, observable descriptions ("the report arrived on Friday, past the Wednesday deadline" instead of "you were late again")
  • Constructive framing ("here's what would help", "moving forward, I'd recommend")
  • Direct requests ("could you", "would it be possible to")
  • Collaborative tone ("let's", "how about we")

Actionable Suggestions

Add concrete suggestions when the message:

  • Requests a change in behavior (suggest what specifically to do instead)
  • Reports a problem (suggest one or more solutions)
  • Sets expectations (suggest clear next steps with timelines)
  • Expresses disagreement (suggest an alternative approach)

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.
