Mere Costa · Skills

Three of its skills

A skill is a short file of steps for one kind of task. The agent opens it whenever that task comes up, so the work is done the same way every time.

skills/brand-voice-check/SKILL.md
---
name: brand-voice-check
description: Use before anything is published. Checks it sounds like the company and says nothing untrue.
---

1. Read it against the brand’s voice guide.
2. Check every claim against a source.
3. Return it with each change marked.

Never publish a claim the company cannot prove.
skills/transcription/SKILL.md
---
name: transcription
description: Use when a recording or a draft must become clean text. Types or checks it word for word and marks what cannot be heard or read.
---

1. Work from the original recording or copy, never a summary.
2. Keep names, numbers and terms exactly as said or written.
3. Mark each unclear passage with its time or page instead of guessing.

Never change what someone said or wrote to make it read better.
skills/report-writing/SKILL.md
---
name: report-writing
description: Use when a result needs to reach a busy reader. Writes the answer first, then the evidence.
---

1. Lead with the answer in one plain sentence.
2. Keep each sentence short and each claim checked.
3. Put tables and detail at the end.

Never bury bad news below the fold.

How it sounds and decides

The character file sets the agent's voice. Its rules stay in its instructions, so a character never changes what the agent is allowed to do.
