AGENTS.md

basilic AGENTS.md is an instructions file for Codex, OpenCode from blockmatic/basilic. It costs 1,137 tokens per session, scanned A, original, MIT.

Repository-specific instructions for working on the Basilic codebase with Cursor-based AI workflows.

In plain words
What is it for?
Use them as guidance when an agent edits or operates in the Basilic repository.
Why use it?
They tell an coding agent how this repository should be handled, including not running parallel processes.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md.

This is blockmatic/basilic's own configuration. It tells Codex and OpenCode how to work on basilic itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything basilic configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

basilic AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 102 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Repository agent instructions

This repository has one shared, Cursor-first AI development workflow. Other agents use the same checked-in rules, skills, and documentation; do not create a second workflow or a competing source of truth.

These instructions apply to the whole monorepo. A nested AGENTS.md adds or overrides guidance for its subtree and must be read before changing files there.

Start here

  1. Read every .cursor/rules/**/*.mdc file with alwaysApply: true.
  2. Read each additional rule whose globs match the files in scope. Repository rules are constraints and override optional skill guidance.
  3. Read the relevant .agents/skills/**/SKILL.md when the user invokes a skill or the task clearly matches one. Workflow and technology skills come from blockmatic/basilic-skills.
  4. Read the matching technical documentation under apps/docu/content/docs/ before changing an architecture, convention, command, or documented behavior.
  5. Read the target app or package README.md and package.json before choosing setup, generation, validation, or test commands.

Search first and keep reads targeted. Inspect the implementation, configuration, and tests instead of relying on memory or assuming that documentation is current.

FIRST decisions

Use FIRST when a task invokes /f-* or requires a durable product, journey, architecture, data, API, documentation, workflow, quality, security, or operations decision. Interface expression is Journeys. Automated delivery is Workflow.

Load FIRST in this order:

  1. _first/AGENTS.md
  2. _first/ABOUT.md
  3. _first/FIRST.md
  4. The primary /f-<station> skill
  5. The station artifact listed in _first/FIRST.md

FIRST station skills live under .agents/skills/f/f-<name>/ and come from blockmatic/first.

Choose one primary station. Load another only when the work crosses a boundary it owns. Do not load _first/maintainers/ for product work. Durable Basilic product intent, feature status, non-goals, and roadmap live in _first/basilic/PRODUCT.md; technical adopter documentation lives in apps/docu.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
