Where files are headingNew AGENTS.md files have more rules about keeping secrets out of the code, and fewer about code style.
Of the AGENTS.md files we read, the 31,843 first seen in the last six months, against the older ones: the kind of rule that gained most share, and the kind that lost most. About files like this in general, not this one, and an estimate, since a kind is a pattern in the words.

The file
We split this agents.md into the rules it gives an agent
5 rules. About 0 are common, 4 are distinctive, and 1 is very specific to this project.

Many files like this have a rule of this kind.

This author's own choices. Worth a look.

Tied to their project's names, files or tools. Probably skip.

Before making protocol-level changes (transports, JSON-RPC handling, capability negotiation), check the latest spec to ensure compliance.

≈ “Common” is an estimate: at least 1 in 5 of the 40,246 AGENTS.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.

Umami MCP Server — Agent Guidelines
Go Style
- Follow Google's Go style guide.
- Prefer the standard library. Only reach for third-party packages when the stdlib genuinely cannot do the job.
- No comments unless an LLM cannot understand what the code is doing from the code alone. If you need a comment, the code is probably too clever.
MCP Protocol
- This server implements the Model Context Protocol.
- Current spec version: 2025-11-25 — reference: https://modelcontextprotocol.io/specification/2025-11-25
- Before making protocol-level changes (transports, JSON-RPC handling, capability negotiation), check the latest spec to ensure compliance.
Before Committing
- Run tests:
go test ./... - Run the linter matching CI (v1 config):
go run github.com/golangci/golangci-lint/cmd/golangci-lint@v1.64.8 run ./... - Fix any lint or test failures before pushing. Do not skip or suppress linter rules without justification.

Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

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.
