Agents Md Generator

AGENTS.md Generator (Root + Nested, Portable)

Goal

Maintain small, high-signal AGENTS.md files:

• Root AGENTS.md — purpose of repository, navigation, universal toolchain, canonical commands, links to docs and skills.
• Nested AGENTS.md — module/package purpose, local commands, module references.

Use progressive disclosure: keep AGENTS.md concise; push details to docs or skills.

---

Skill location (agent-specific)

• Do NOT assume .agents/ or any fixed directory exists.
• Skills may live:
• inside the repository (embedded),
• or in an external/global skill library (external).
• If referencing local skills, use only an existing skill root already used by

the project or an existing project path already mentioned by repo docs.

• If no local skill directory exists — reference skills by name only (external).
• Never create hidden agent directories just to store skills.

---

Resource Routing

Use templates as skeletons, not literal output:

• Read references/AGENTS_TEMPLATE_ROOT.md only when creating or updating the

root AGENTS.md.

• Read references/AGENTS_TEMPLATE_MODULE.md only after a directory is

confirmed as a nested module that needs its own AGENTS.md.

• Replace or remove every placeholder. Final AGENTS.md files must not contain

unresolved `` template markers.

---

When to run

Run this skill when:

• AGENTS.md is missing, bloated, contradictory, or outdated.
• AGENTS.md needs to be generated, repaired, trimmed, split, or updated.
• A new package/service/module appears.
• Repository structure changes (monorepo growth or split).
• Teams want consistent agent context across diverse stacks.

---

Workflow (Deterministic)

1. Discover repository shape

• Identify repository root (git root if available).
• Detect language/tool markers:
• package.json, pnpm-workspace.yaml
• go.mod, go.work
• pyproject.toml
• Cargo.toml
• pubspec.yaml
• pom.xml, build.gradle
• Locate docs/, README.md, existing AGENTS.md.

---

2. Detect module boundaries

Create nested AGENTS.md if directory:

• Contains independent build/package manifest
• OR represents deployable/service unit (apps/, services/, packages/)
• AND adds distinct commands, docs, ownership, deployment notes, or toolchain

guidance compared with parent scope.

Do not create a nested AGENTS.md that only repeats the root instructions.

---

3. Generate/Update Root AGENTS.md

Constraints:

• Ideal size: ≤ 60 lines
• Must include:
• One-sentence repository purpose
• Primary toolchain/package manager
• Canonical commands (if non-standard)
• Links to docs
• Instruction to read nested AGENTS.md when inside modules
• Optional skill references (adaptive: local or external)
• Preserve verified commands, docs, security/secrets/deployment warnings, and

important local rules from any existing root AGENTS.md.

---

4. Generate/Update Nested AGENTS.md

Constraints:

• Ideal size: ≤ 40 lines
• Must include:
• One-sentence module purpose
• Module-specific commands
• Local documentation references
• Optional skill references (adaptive)
• Preserve verified module warnings, ownership, deployment notes, and local

rules from any existing nested AGENTS.md.

---

5. Progressive Disclosure Rules

• Do not embed style guides, CI policies, or architecture details.
• Prefer links to existing docs and external or local skills.
• Include only links that exist or are explicitly cited as the source for

commands or policy.

• Replace stale long-form sections with links when an authoritative doc exists.
• Avoid “always/never” rules unless critical for correctness/security.

---

6. Safety / Correctness Gates

• Never invent commands.
• Infer commands from:
• package scripts
• Makefile
• CI configuration
• README
• If uncertain → write:

“Known commands: see ”

• Preserve critical warnings (security, secrets, deployment).

---

Output Contract

Create or update only:

• /AGENTS.md
• /AGENTS.md

Do not create agent configuration folders.

---

Skill Referencing Strategy

When adding skill references inside AGENTS.md:

1. If local skill directory detected

`` See: //SKILL.md ``

1. If no local directory exists

`` Skill: agents-md-generator (external) ``

Never assume filesystem paths.

---

Validation

Before finishing, verify:

• Only root/module AGENTS.md files were created or updated.
• Final AGENTS.md files contain no unresolved `` placeholders.
• Relative documentation links exist or clearly point to a source file for

commands/policy.

• Commands are supported by package scripts, Makefile, CI configuration, or

README. If no command is verified, use Known commands: see .

• Line budgets are respected: root ≤ 60 lines, nested module ≤ 40 lines.
• Nested files exist only for confirmed module boundaries.
• Critical warnings from existing AGENTS.md files are preserved.
