Repository instructions for CDC Open Viz, a project for creating visualisations. They explain how to compare branches, find tests and Storybook stories, choose test scope, and maintain configuration documentation.

In plain words
What is it for?
Use them to select targeted tests, inspect component stories, compare feature branches with dev, and update package configuration docs.
Why use it?
They reduce unnecessary full test runs and provide the project’s expected process for checking changes.

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

This is CDCgov/cdc-open-viz's own configuration. It tells Codex and OpenCode how to work on cdc-open-viz 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 cdc-open-viz 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

cdc-open-viz 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 7d 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.

Super Intelligence (SI) Agent Instructions

This file helps Super Intelligence (SI) coding assistants understand how to work with this repository. Use it as an index to these sections:

Branch Comparison

Feature branches usually branch from dev; compare against dev by default when determining what a feature contains.

Testing Commands

Use repo-local script commands for consistency (yarn ...) and avoid relying on a globally installed lerna.

Required Test Strategy

  • Default to targeted tests for the files/components you changed.
  • If changes span many areas, run quick suites.
  • Do not run full suites unless the user explicitly asks for them.

Targeted Tests (Default)

For unit targeting, copy this root command shape exactly; both -- separators are required.

  • Unit tests for one package/file:
    • Use package-relative test file paths after --scope, not repository-root paths.
    • yarn test-unit:quick -- --scope @cdc/<package-name> -- src/.../<file>.test.<js|jsx|ts|tsx>
    • Example: yarn test-unit:quick -- --scope @cdc/dashboard -- src/test/CdcDashboardComponent.test.tsx
  • Storybook tests for one story file:
    • yarn test-storybook:quick packages/.../_stories/<file>.stories.<js|jsx|ts|tsx>
    • Example: yarn test-storybook:quick packages/chart/src/_stories/ChartEditor.stories.tsx

Quick Suites (For Broad Changes)

  • Unit quick mode (bypasses standalone build checks by setting COVE_QUICK_TESTS=1):
    • yarn test-unit:quick
  • Storybook quick mode (sets COVE_QUICK_TESTS=1 and excludes files matching *.smoke.stories.<js|jsx|ts|tsx>):
    • yarn test-storybook:quick

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.
