done

A session-logging tool for Obsidian, a note-taking application. It turns a finished coding-agent session into a dated Markdown note and links that note from the day's daily note.

In plain words
What is it for?
Use it to document completed work, decisions, code snippets, and file changes from an agent session.
Why use it?
It records what happened during a session without requiring you to write the summary and links by hand.

Made for: Claude Code, Codex.

Per session 44 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.

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

done 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 3d 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 — 89 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Summarize this Claude Code session, create a dedicated session note in Obsidian, and link it from today's daily note.

Instructions

  1. Review the full conversation history for this session.
  2. Come up with a short summary title (2-6 words, no date) describing the overall theme.
  3. Write a detailed session note in markdown. The note MUST begin with YAML frontmatter and then use the sections described below. Skip any sections that don't make sense. The only non-negotiable is the frontmatter, which must always be present. Use this template:
---
created: YYYY-MM-DD
project: <working directory name or repo name>
harness: <who you are ('claude-code', or 'codex', or 'pi', etc)>
tags:
  - note/agent-session
---

# <summary title>

## Summary

<1-3 sentence overview of the session>

## What was done

- <bullet list of key actions, changes, and outcomes>

## Decisions made

- <bullet list of decisions and the reasoning behind them>
- <include trade-offs considered, alternatives rejected, and why>

## Relevant code snippets

<relevant new commands that were created, code snippets that were mentioned, etc>

## File changes

- `path/to/file` -- <what changed and why>
- <list every file that was created, modified, or deleted>

## Deferred / Postponed

- <anything discussed but intentionally left for later>
- <known issues discovered but not addressed>
- <if nothing was deferred, write "None">

## Notes

- <any additional context, gotchas, or follow-up items>
- <if $ARGUMENTS was provided, incorporate that context here or in the relevant section above>

Be thorough -- err on the side of detail. The goal is a complete record of the session. 4. Get today's date in YYYY-MM-DD format and construct the note path: Reference/Agent Sessions/YYYY-MM-DD <summary title> 5. Find the full path to the Obsidian vault by running obsidian vault - the path will be listed. 5. Create the session note file at /Reference/Agent Sessions/YYYY-MM-DD .md 6. Append a link to the session note in today's daily note by running:

obsidian daily:append content="- [[YYYY-MM-DD <summary title>]]" silent

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.

done is a skill published in the GitHub repository fredoliveira/agents (24 stars, last pushed 2mo ago), licensed MIT. It adds 44 tokens to every session and 788 once invoked, about $0.0002 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 2026-08-30.
