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 31,700 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.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈4
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 31
Do not store todos on disk: Do not create TODO.md, todos.json, or any other todo-tracking file.
- Distinctive: line 40
If the todo API is unavailable, state that in the response and list todos inline as a fallback - still do not write a file.
- Distinctive: line 48
No git commands without explicit permission: Never run git add, git commit, git push, git restore, git clean, git reset, or git stash …
- Distinctive: line 52
Use plain hyphens or restructure.
- Distinctive: line 68
Run targeted checks during a session.
≈ “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.

Project
[Placeholder - add a short description of what this repo owns, who it is for, and what it is not.]
- Module:
[Placeholder - e.g. github.com/org/repo] - GitHub repo:
[Placeholder - https://github.com/org/repo] - Default branch:
[Placeholder - e.g. main / master] - Binaries / libraries / apps:
[Placeholder - what gets built and shipped] - Pipeline / architecture overview:
[Placeholder - stages, owners, data flow]
Todo protocol - response-only (mandatory)
[Placeholder - keep, adapt, or remove per project. Default below is generic.]
- Create todos in the response via API before any work. On receiving any
task (feature, fix, docs, question with multi-step work), immediately call
the todo API (
todowriteor equivalent) to publish the plan as todos. Do not start work until the todo list is visible in the API response. - Show current todos in every response. Each assistant turn must render
the current todo list with status markers (
pending,in_progress,completed,cancelled) and clearly highlight which item isin_progress. - Do not store todos on disk. Do not create
TODO.md,todos.json, or any other todo-tracking file. Todos live only in the API response state. - Keep response todos updated as you go. Mark items
in_progresswhen started andcompletedwhen finished. If scope changes, update the list immediately. - Completion requires todos to show done. A task is done only when all
todos show
completedand you have sent a final summary stating what shipped.
If the todo API is unavailable, state that in the response and list todos inline as a fallback - still do not write a file.
Golden rules
[Placeholder - replace with project-specific working agreements. Keep only what applies.]
- No git commands without explicit permission. Never run
git add,git commit,git push,git restore,git clean,git reset, orgit stashunless the user asks. - No em dashes ("--") in any written output, docs, or commit messages. Use plain hyphens or restructure.
- [Placeholder - branch naming convention]
- [Placeholder - PR / issue template and process]
- [Placeholder - checklist / ledger update rule]
- [Placeholder - writing / docs quality bar]
Verification gates
[Placeholder - list the real gates that prove a change is safe. Replace the example rows below.]
| Gate | Command | What it proves |
| [Placeholder] | [Placeholder - e.g. make test] | [Placeholder] |
| [Placeholder] | [Placeholder - e.g. make lint] | [Placeholder] |
Run targeted checks during a session; run the full gate set once at session end before claiming done.
Things to AVOID
[Placeholder - add paid-for lessons specific to this repo. Remove generic examples below if they do not apply.]
- [Placeholder - e.g. guessing APIs without grepping]
- [Placeholder - e.g. claiming completion without gate output]
- [Placeholder - e.g. scope creep]
Code structure
[Placeholder - describe layout, file size limits, module split strategy, and verification after moves.]

FAQ - does the root AGENTS.md get read automatically?
Yes. Creating AGENTS.md at the repo root is the standard, and it is read
automatically by every major tool: opencode, codex, gemini CLI,
antigravity/agy, grok, claude code, cursor. You do not need anything under
.agents/. Keep this one file at the root and keep it current.
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.

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.
