Agent authoring conventions including frontmatter fields, reload behavior, and validation
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 31,774 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.
In this repository52 other files it gives its agents.

The file
We split this agents.md into the rules it gives an agent
2 rules. About 0 are common, 0 are distinctive, and 2 are very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈0
Distinctive · estimate
This author's own choices. Worth a look.
2
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Very specific: line 30
Use the plugin-dev:plugin-validator agent to validate agent definitions before merging.
- Very specific: line 34
When adding or removing an agent, update the agents table in README.md so the documented agent list stays in sync with the actual contents …
≈ “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.
Files
Agent definitions live at agents/<name>.md as markdown files with YAML frontmatter.
Frontmatter fields
name: kebab-case identifierdescription: Delegation trigger: what the agent does and the situations that should route to it. Add urgency such as "Use PROACTIVELY" only for an agent that demonstrably under-delegates, scoped to that situation.tools: Allowed tools. Two accepted forms:- Comma-separated scalar string:
tools: "Bash, Read, Grep" - YAML list (required when entries contain colons or spaces):
tools:\n - Read\n - "Bash(jq:*)"Omit the field to inherit all tools from the parent session.
- Comma-separated scalar string:
model:inherit,haiku,sonnet, oropusskills: Skills to autoload (subagents don't inherit parent skills)permissionMode:default,acceptEdits,bypassPermissions,planmemory: Persistence scope.userstores memory per-user across sessions. Version-sensitive: verify against the installed Claude Code release.color: Label color shown in the Claude Code UI (e.g.cyan). Version-sensitive: verify against the installed Claude Code release.
Reload behavior
Agents require a Claude Code restart to pick up changes. Skills, by contrast, hot-reload.
Validation
Use the plugin-dev:plugin-validator agent to validate agent definitions before merging.
Documentation sync
When adding or removing an agent, update the agents table in README.md so the documented agent list stays in sync with the actual contents of agents/.
Does it work?

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.
