naming

A naming guide for the Grida code repository. It focuses on choosing names that clearly define what a module or package should contain and help prevent unrelated code from being added.

In plain words
What is it for?
Use it when naming modules, packages, files, or exported concepts, especially before creating new code or deciding where a feature belongs.
Why use it?
It addresses the maintenance problems caused by vague or misleading names, which make code boundaries harder to understand and change safely.

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

naming 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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 218 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Naming

Vanilla conventions (snake_case in Rust, kebab-case in JS/TS, PascalCase exports, use-* hooks) are table stakes — assume them. This document is about the observations on top: what a name commits you to, what it reveals, and what it costs when it's wrong.

Name first

Pick the name before the types, before the tests, before the file exists. If the name doesn't come easily, the design isn't ready — don't start coding; sharpen the concept until the name falls out. Maintainability is downstream of naming. How a module grows, how cleanly it retires, how safely it can be deleted — all of it is decided at the moment you choose what to call it.

A strict, honest name is a scope gate

A name's primary job here is to refuse the wrong content. A module called painter should feel actively wrong to host a layout helper; a package called @grida/cmath should feel wrong to host color logic. The strictness is deliberate — it is the mechanism that keeps features from leaking into each other.

"Strict" requires "honest." A name that no longer describes what's inside has stopped being a gate: it won't reject foreign additions, and new readers can't trust it. When contents drift past the name, you have two moves — rename to match what the module has become, or extract the drifted pieces out — and you must pick one promptly. Letting a name go stale is how codebases rot quietly.

Three consequences cascade from the gate discipline, and together they produce the current repo structure:

  1. Modules stay shallow. You will rarely see a module nested deeper than two levels inside a crate's src/ or a package's src/. When you're tempted to grow a third level, the parent's name has stopped describing what's inside — flatten or extract, don't nest.
  2. Flatten with prefixed siblings, or collapse into one file. Before reaching for a subdirectory, ask whether the new thing is a sibling variant of an existing file (painter.rs + painter_debug_node.rs + painter_geometry.rs) or whether it collapses into the existing file. Both preserve the parent's scope; a new subdirectory quietly widens it.
  3. If it resists flattening, it is a new module. The thing that won't fit under the strict name doesn't belong there. It wants its own tiny, agnostic package or crate. The repo has many small @grida/* packages and small crates precisely because this extraction was made each time a sibling would have diluted the parent's name.

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

naming is a skill published in the GitHub repository gridaco/grida (2,629 stars, last pushed 11d ago), licensed Apache-2.0. It adds 94 tokens to every session and 2,350 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
