What is keyboardia AGENTS.md?

A project instruction file for Keyboardia, a multiplayer step sequencer with a React client, a Cloudflare Worker, and an MCP server. It lists the commands and rules used to verify changes.

Use it when changing the Keyboardia project to find the relevant validation, unit-test, lint, and browser-test commands. CI, or continuous integration, automatically runs some of these checks for proposed changes.

It gives a coding agent the project's own checks instead of making it guess how to test a change. It distinguishes quick checks from targeted and full browser checks.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00870	$0.00870
Opus 5.5	$0.00348	$0.00348
Sonnet 5.5	$0.00174	$0.00174
Haiku 4.5	$0.00087	$0.00087

Security

Grade A, and why

keyboardia 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 27d 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.

Agent guide

Keyboardia is a multiplayer step sequencer: a React client, a Cloudflare Worker with Durable Objects, and an MCP server. Code and tests live in app/; run the commands below from app/. Testing policy is enforced by executable gates, so this file lists them rather than restating them. Details: specs/TESTING.md.

Verify a change

Tier	Command	When
T0	`npm run validate:manifests && npm run validate:e2e-inventories && npm run test:unit`	Before every push. The pre-push hook runs exactly this.
Heavy unit lanes	`npm run test:audio-render` and `npm run test:verification-tooling`	When you touch audio rendering or the verification tooling. CI runs both on every PR.
T1	`KEYBOARDIA_VERIFY_T1=1 git push`	Targeted browser lanes. CI picks T1 profiles from the changed paths (`scripts/select-verification-scope.mjs`, `e2e/verification-impact.json`); an unmatched path selects every profile.
T2	`KEYBOARDIA_VERIFY_T2=1 git push`	Full desktop browser matrix against a local Worker. CI runs it on push to `main`, weekly and on dispatch.

Also run what CI runs for the files you touched: npm run lint, npm run typecheck, npm run validate:test-quality, and npm run test:integration (Workers runtime; run npm ci in test/integration first).

Gates CI blocks on

validate:test-antipatterns: tests that cannot fail (swallowed assertions, runtime self-skips, tautologies, tests with no assertion).
validate:test-links: a test must import the module it is named after and must not reimplement it; a module imported only by its tests is dead.
validate:dead-exports: no runtime export that only tests reach.
validate:unrun-tests: every test file is collected by some lane.
Playwright lane contracts (scripts/assert-playwright-stats.mjs): exact passed and skipped counts, flaky: 0, unexpected: 0, and exact test identities from e2e/lane-contracts.json and e2e/lane-identities.json. Adding, renaming or skipping an E2E test means updating those files in the same change (npm run update:e2e-lane-identities), where a reviewer sees it.

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.
