The file
We split this CLAUDE.md into the rules it gives an agent
2 rules. About 0 are common, 1 is distinctive, and 1 is very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈1
Distinctive · estimate
This author's own choices. Worth a look.
1
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Very specific: line 22
Prefer append_note over rewriting.
- Distinctive: line 27
Write notes the user will still understand in a year: complete sentences, context included, no conversation-specific shorthand.
≈ “Common” is an estimate: at least 1 in 5 of the 26,980 CLAUDE.md files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Agent instructions for this vault
You are working inside the user's second brain, a big-brain markdown vault. Treat it as their external memory: read it before answering questions about their work, and write to it as things happen, not at the end.
Orientation
At the start of a session that touches ongoing work, get the lay of the land first: call the brain_overview MCP tool (or run big-brain status). Don't guess what the user is working on when the vault can tell you.
When to write
- Something worth keeping, unclear where it goes →
captureto inbox. Never let information die in the conversation. - A decision was made, progress happened, something broke → one line via
daily_log, and to the relevant project'sLogsection if it belongs to a project. - New commitment with multiple steps →
create_project(statusactive, a clear Goal). - New action item →
add_taskon the project it belongs to; only use the daily note for one-off errands. - Learned something durable (how a system works, a config that matters, a person's role) → a note in
notes/,reference/, orpeople/with[[wikilinks]]to related notes.
Conventions
- Wikilinks (
[[Note Title]]) are the connective tissue. Link every new note to at least one existing note or project. - Frontmatter drives structure:
type,status,tags,due. Updatestatuswithset_project_status/update_frontmatterrather than editing prose. - Tasks are
- [ ]checkboxes. Metadata:📅 YYYY-MM-DDdue,⏫high priority,✅completion date (added automatically bycomplete_task). To reschedule, reprioritize, reword, reopen, or cancel (- [-]) a task, useupdate_taskrather than rewriting the note. - Prefer
append_noteover rewriting; never delete. Usearchive_noteinstead. - Dates are absolute (
2026-07-07), never "yesterday" or "next week".
Tone of vault content
Write notes the user will still understand in a year: complete sentences, context included, no conversation-specific shorthand. A note should stand alone.
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
