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

flows-review-checks scanned grade A with 1 finding 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 3d 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.

How it starts

The opening of the file, as written. The whole thing — 475 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Flows review checks (shared)

This file is the public definition of what a Flows technical review must search for in this repo, how strict each bar is, and how to score 1.1, 1.3–1.6, 2.1–2.6, 3.1.

It does not decide:

  • whether you build the app
  • Codespace vs local
  • Jira / Zendesk / git round folders
  • output paths (reviews/code-review/… vs reviews/external-submissions/…)

The caller sets those. Then it reads this file and runs every check.

Do not edit the app. Do not “fix it now.”

Load code-quality from the same cognitedata/builder-skills repo (see hunt 1.5). Run its searches. Ignore every “fix / replace / write the file / pnpm add” instruction in that skill. Other skills (test-coverage, …) stay fixers and are not the review bar.

Caller contract

Before any command in this file:

  1. cd to the app root (the directory with package.json and src/).
  2. All greps and test/coverage commands run from that directory.
  3. The caller names where to write artifacts. This file only defines content.

If a search was not run, that check is not a pass.

What the caller must produce

Whatever the filenames, the review must include:

  1. File inventory — every .ts/.tsx except node_modules, dist, .cognite-bundles. Include vitest.config.* / vite.config.* / jest.config.*. Columns: Structure, Quality, Patterns, Tests, Notes. Then read every non-trivial production file (skip barrels, generated types, tests).
  2. Findings — every hunt below, with hits or none. Then must / should / nice with file:line.
  3. Package audit — Step 2 in this file.
  4. Scored report — criteria 1.1, 1.3–1.6, 2.1–2.6, 3.1, must/should/nice lists, _Impact:_ on every Must Fix.

A 1–2 on any criterion is Must Fix. 3 is Should Fix. Gaps at 4 are Nice Fix.


Step 1 — Hunt

Run every command. Do not sample src/ and stop.

1.1 Coverage and test config (criterion 1.4) — before you believe any %

Read vitest.config.*, vite.config.* (test / coverage blocks), and jest.config.*. Then:

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.
