AGENTS.md

console-toolkit AGENTS.md is an instructions file for Codex, OpenCode from uhop/console-toolkit. It costs 1,144 tokens per session, scanned A, original, BSD-3-Clause.

A set of AGENTS.md instructions for the console-toolkit project, a zero-dependency JavaScript library for terminal and text-based interface output.

In plain words
What is it for?
Guiding changes to console-toolkit while preserving its ESM structure, hand-written type files, source layout, and testing expectations.
Why use it?
It tells coding agents the project's required module format, file conventions, dependency policy, style, and type-definition rules.

Instructions file for CodexOpenCode

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

This is uhop/console-toolkit's own configuration. It tells Codex and OpenCode how to work on console-toolkit 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 console-toolkit 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

console-toolkit 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 1mo ago.

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.

console-toolkit — AI Agent Rules

Project identity

console-toolkit is a zero-dependency ESM JavaScript library for rich CLI/TUI output: styled text, boxes, panels, tables, charts, plots, turtle graphics, spinners, and progress bars. Node.js 22+, Bun, Deno.

Critical rules

  • ESM-only. All imports must use .js extensions: import Box from './box.js'.
  • No runtime dependencies. Never add packages to dependencies. Only devDependencies are allowed.
  • No build step. Source JS in src/ is shipped directly. Do not create build scripts or compiled output.
  • Hand-written .d.ts files. They are NOT generated. When modifying a public API, update both the .js and .d.ts files.
  • No JSDoc in .js files. API contracts live in the sidecar .d.ts only. Don't add /** ... */ blocks to src/*.js; they duplicate the .d.ts and rot out of sync.
  • Do not modify or delete test expectations without understanding why they changed.

Code style

  • Prettier: 120 char width, single quotes, no bracket spacing, no trailing commas, arrow parens "avoid".
  • 2-space indentation (.editorconfig).
  • Imports at top of file. No dynamic imports unless necessary.
  • Comments are why-markers only — a non-trivial decision/constraint or an algorithm reference; never narration of what the code does. Type docs live in the .d.ts, not as JSDoc in .js.

Architecture quick reference

  • Box is immutable — methods return new Box instances.
  • Panel is mutable — methods mutate this and return this for chaining.
  • Method aliases use addAlias/addAliases from meta.js.
  • pad(t, r, b, l) follows CSS shorthand order.
  • Three text containers convert between each other: strings (string[]), Box, Panel.
  • SGR styling: Style class with fluent API; s/c tagged template literals.

Writing tests

Tests use tape-six. For the full testing API, patterns, and conventions see node_modules/tape-six/TESTING.md.

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.
