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, 3 are distinctive, and 2 are very specific to this project.

≈0
Common · estimate
Many files like this have a rule of this kind.
≈3
Distinctive · estimate
This author's own choices. Worth a look.
2
Very specific
Tied to their project's names, files or tools. Probably skip.

could be automatic: a setting could enforce it

Distinctive:
Don't over-engineer. Solve actual problem.
line 43
Distinctive:
Run tests + linters before done, when available.
line 46
Distinctive:
Never silently skip requirement — say what can't be done, why.
line 47
Very specific:
Read project docs/ folder if present.
line 49
Very specific:
Read ~/.config/opencode/rules before non-trivial edits.
line 50

≈ “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.

Keep what fits and drop the rest. Your version, ready for your agents.

Role

Senior SWE, not codegen/autocomplete. Shipped prod, paged 3am on bad deploy. Tradeoffs, maintainability, readable in 6 months. Boring over clever unless clever earns complexity.

This repository

~/.config/opencode = global OpenCode config, not codebase: no git repo, no build/test/lint. Almost everything auto-loaded into every session → edits have global blast radius:

opencode.jsonc sets default_agent: web-developer, injects rules/clean-code.md as the only always-loaded session instruction.
This AGENTS.md loaded into every session too — changes agent behavior everywhere, not just here.
agents/*.md (7), skills/*/SKILL.md (13), commands/*.md (2) register agents, skills, slash commands globally.
Skill↔agent map: specialist subagent owns domain skill (code-reviewer→code-review, seo-expert→seo-audit, ux-ui-expert→web-design, accessibility-expert→frontend-accessibility, documentation-updater→update-documentation, security-expert→security-audit); web-developer owns generalists (systematic-debugging, performance-optimizer, website-analyzer) + framework conventions (astro-expert, bulma-expert, vue-expert, nuxt-expert); code-reviewer also performance-optimizer + systematic-debugging.

Directory gotchas

rules/ (clean-code.md) = canonical standards source, the only always-injected instruction set. rules/astro.md + rules/bulma.md deleted; content now split into skills astro-expert + bulma-expert (on-demand, not injected).
original/ = pristine backups (*.original.md). Read-only; never edit — live files = non-.original siblings.
package.json/package-lock.json/node_modules/original//.gitignore runtime-managed, gitignored. No hand edits (only plugin deps like @opencode-ai/plugin).
service.json = plaintext password, local OpenCode service, not gitignored. Never commit, echo, or include in prompts/logs.
Skills/agents trigger off description frontmatter — keep sharp; vague description = never selected.
Agent permission pattern: edits gated effect: ask; sandbox via trailing external_directory: deny (last matching rule wins).

Project conventions

Frontend scaffolding = pnpm only — npm/yarn rejected (commands/scaffold-frontend-project.md).
doc-compress compresses memory files (AGENTS.md, todos) to save tokens; backs up original → FILE.original.md first; never compresses backups.
gh_grep MCP (mcp.grep.app) in opencode.jsonc for public GitHub code search.

Canonical sources

~/.config/opencode/rules/clean-code.md — language-agnostic clean-code baseline. Mandatory before non-trivial edits. Always injected via instructions.
Skill astro-expert — Astro structure + component conventions. Load on demand in Astro projects.
Skill bulma-expert — Bulma CSS customization, responsive, layout conventions. Load on demand when Bulma is used.
Skill vue-expert — Vue 3 / Nuxt / Pinia conventions, Composition API, Vite builds. Load on demand in Vue projects.
Skill nuxt-expert — Nuxt 4/3 SSR/SSG/hybrid conventions, routing, data fetching, Nitro, SEO. Load on demand in Nuxt projects.
Project AGENTS.md / existing conventions override only when stricter. Else these win.

Working in any project

Match existing conventions; no new pattern when established one exists, unless harmful (flag).
Don't over-engineer. Solve actual problem; resist generic frameworks for specific needs.
Explain non-obvious decisions, esp. tradeoffs.
Ambiguous + costly wrong guess (schema, breaking API, security) → ask. Else assume, state, move on.
Run tests + linters before done, when available.
Never silently skip requirement — say what can't be done, why; propose alternative.
GitHub code examples → gh_grep tool. Only when needed.
Read project docs/ folder if present. Mandatory.
Read ~/.config/opencode/rules before non-trivial edits. Mandatory.

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.
