capture

A tool for saving useful ideas from a coding session as individual notes in an Obsidian vault. Obsidian is a note-taking application that stores linked notes.

In plain words
What is it for?
Use it to record design ideas, future things to build, and other reusable insights in the configured devkb folder.
Why use it?
It keeps reusable ideas from being lost in a chat or buried in temporary work notes. It can save one specific idea or review the session for ideas worth keeping.

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

capture 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 yesterday.

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.

The opening of the file, as written. The whole thing — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/devkb:capture — save session ideas to your Obsidian knowledge base

Turn ideas that came up while working into durable, linkable notes in the user's Obsidian vault. Two modes:

  • A specific idea — the user points at one thing ("save that idea about caching the cost snapshot"). Capture just that.
  • Sweep the session — the user asks to capture everything worth keeping ("grab any ideas from this session"). Scan the conversation and pull out the genuinely new, reusable ideas.

Curate. An idea worth a note is a reusable insight, design direction, or thing-to-build — not a task you just finished, a bug you fixed, or routine status. When in doubt, prefer fewer, sharper notes over many thin ones.

Where the vault is

Read the vault path from ~/.config/mesh44/config.json:

{
  "obsidian": {
    "vault": "/Users/<you>/Documents/Obsidian Vault",
    "folder": "devkb"
  }
}
  • Notes go in a devkb folder inside the vault. If obsidian.folder is unset, default to devkb; if the obsidian key is missing entirely, default to ~/Documents/Obsidian Vault and devkb — and tell the user you're using the default and they can set obsidian.vault / obsidian.folder to change it.
  • If the vault directory doesn't exist, ask the user for the vault path rather than guessing. Never write outside the vault.
  • Create <vault>/<folder>/ if it doesn't exist yet.

Where in the folder — general vs project

The <folder>/ is organised into two kinds of subfolder:

  • <folder>/general_learnings/ — cross-project, reusable insights: a pattern, a gotcha, a principle, a technique that would apply on any project.
  • <folder>/<project>/ — anything specific to the project this session is about (an idea for this app, a decision, a thing to build here).

For each idea, decide which it is. Derive <project> as a clean slug from the repo/cwd — e.g. a session in www.mesh44.com is project mesh44 (drop a leading www. and a trailing TLD-like suffix). If a matching project folder already exists, reuse it exactly rather than making a near-duplicate. When genuinely unsure, prefer the project folder — it's easy to promote to general_learnings/ later.

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.

capture is a skill published in the GitHub repository jpd44/mesh44-plugins (2 stars, last pushed 1mo ago), licensed MIT. It adds 58 tokens to every session and 1,087 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
