note

note is a skill for Claude Code, Codex from escoffier-labs/brigade. It costs 96 tokens per session (1,317 once invoked), scanned A, original, MIT.

A workflow for creating an Obsidian note, which is a Markdown file used for linked personal knowledge. It records either a reproducible troubleshooting fix or a clear explanation of a topic and places the note in the configured notes folder.

In plain words
What is it for?
Documenting bugs and their fixes, capturing system or coding concepts, recording workflows and architecture decisions, and saving the result to an Obsidian inbox.
Why use it?
It keeps useful session knowledge from disappearing after the conversation ends. The chosen format makes commands, concepts, and reasons easier to find later.

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

note 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 5d 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 — 174 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/note - Create Obsidian-Formatted Notes

Create an Obsidian-formatted markdown note and place it in ~/notes/. Tell the user the exact file path and confirm the sync.

If the user provided a topic argument after /note, use it as the topic. Otherwise, review the conversation to identify the topic.

When to use

Two distinct modes. Pick the right one before you start writing.

Mode When
Verbatim fix capture Troubleshooting sessions, root-causing bugs, recovering from incidents. The fix needs to be reproducible step-by-step. Future-you will paste the exact commands.
Summarize / concept Learning something new, capturing a workflow, documenting a system. The reader needs to understand why, not just how.

Common triggers:

  • Troubleshooting sessions - issues, errors, and the fix that worked
  • System concepts - how things work on Linux, networking, services, frameworks
  • Coding knowledge - languages, libraries, patterns, gotchas
  • Development workflows - tools, commands, configurations
  • Architecture decisions - what was chosen and why

Process

  1. Decide which mode applies. If unclear, ask: "Should I write this verbatim (reproducible) or summarize the concept?"
  2. Review the conversation to identify the topic and pull the relevant commands, errors, paths.
  3. Write the .md file to ~/notes/<topic-slug>.md.
  4. Sync to the configured Obsidian inbox (see "Sync target" below).
  5. Tell the user the exact file path and confirm the sync.

Note format

YAML frontmatter

Every note MUST start with YAML frontmatter:

---
tags:
  - tag1
  - tag2
created: YYYY-MMM-DD
---
  • 3-5 relevant tags. Lowercase, hyphenated for multi-word.
  • Date format YYYY-MMM-DD (e.g. 2026-Jan-24).
  • Add mode: verbatim or mode: concept if you want the mode visible in frontmatter.

Structure: verbatim fix

## The problem

> [!bug] Title
> Brief symptom. Paste the actual error string verbatim.

Context. What was the system doing. What changed recently.

## The fix

> [!success] Title
> The exact command(s) that worked.

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
