What it does
Brief Generation is an agent skill from grandamenium/cortextos. Generate source-backed markdown briefs and run summaries for selected research signals.
Its SKILL.md is about 880 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The licence is MIT.
Example prompts
- “/brief-generation”
What it can do on your machine
Read from SKILL.md and the folder at commit 6f93838. 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 (its code samples are markdown).
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
Brief Generation loads about 880 tokens when it runs. Until then it costs about 26 tokens; SKILL.md has 163 words of instructions outside code blocks.
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.

Brief Generation
Write a structured markdown brief for each selected signal.
When to Use
After signal-scoring selects the top N items.
Input
research/output/YYYY-MM-DD/signals-selected.jsonconfig.json(for voice, audience, output folder)
Output
research/output/YYYY-MM-DD/briefs/SLUG.md(one file per selected signal)research/output/YYYY-MM-DD/summary.md(run summary across all briefs)
Brief Format
Each brief file follows this structure:
# [TITLE]
**Date:** YYYY-MM-DD
**Source:** [source_name] -- [url]
**Author/Channel/Repo:** [author]
**Category:** [category] | [funnel_stage] | [output_type]
**Score:** [score]/10
---
## Executive Summary
2-3 sentences. What is this? Why does it matter right now?
---
## Evidence and Proof Points
- Specific facts, numbers, dates, quotes from the source
- Raw metrics: stars, views, engagement, score
- Growth signals if applicable
---
## Technical Details
What is technically happening here? Relevant for builders and technical audiences.
(Skip or condense for non-technical signals.)
---
## Why It Matters
1-3 concrete reasons this is worth paying attention to.
Tied to the configured target audience and niche.
---
## Content Angles
- [Angle 1]: one sentence describing the hook or frame
- [Angle 2]: ...
- [Angle 3]: ...
Include at least 2, up to 5.
---
## Suggested Hooks
> "Quote or opening line that could start a piece of content"
> "Alternative hook"
---
## Recommended Action
One of: create content, investigate further, share internally, monitor, no action needed.
One sentence explaining why.
---
## Confidence and Freshness
- **Confidence:** high / medium / low (based on source quality and completeness of data)
- **Freshness:** [published_at] -- [N days old]
- **Shelf life:** [urgency score interpretation: breaking / 24h / 1 week / evergreen]Writing Rules
- Lead with the finding, not the process.
- Use the voice and audience defined in config (e.g. "technical founders building with AI" vs "content creators").
- Proof points must come from the source. Do not add claims not supported by the fetched data.
- Content angles must be specific. "Here's a content angle" is not a content angle. "The security incident shows that centralizing OAuth tokens at a vendor is an architectural liability -- frame as why to own your credential layer" is a content angle.
- If a brief cannot be written with enough evidence (source returned only a title), mark confidence as
lowand note what additional research is needed.
