flows-code-review

flows-code-review is a skill for Claude Code from cognitedata/builder-skills. It costs 97 tokens per session (1,190 once invoked), scanned A, original, Apache-2.0.

A technical review process for Cognite Flows apps that checks source files, packages, correctness, security, dependencies, and tests, then records a scored report.

In plain words
What is it for?
Use it to perform the code-review stage of Flows app certification and produce review files and a report.
Why use it?
It gives a repeatable way to find implementation problems before an app moves through certification. The findings are grouped by how urgently they need attention.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • high Memory Poisoning · line 333
    Skill manipulates agent memory, state, or stored context. Memory corruption can alter personality, override safety rules, or cause unpredictable behavior.
    Fix: Protect agent memory and state from modification by untrusted content. Use read-only memory for critical instructions and validate all state changes.

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-code-review 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 2mo 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 — 112 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Flows Code Review

This skill is the local runner for the technical review step:

flows-app-brief  →  build  →  flows-code-review (this skill, repeat until clean)  →  flows-design-review  →  flows-external-app-submit

Checks and scoring live in flows-review-checks. Do not copy them here. Do not score from memory. Do not substitute test-coverage or other fix skills for the review bar.

This file only decides: git/app-brief pre-checks, feedback-round folder, that the working directory is the app root, where to write files, and the submitter Summary block.

Pre-checks

  • package.json exists
  • We are inside a git repository (git rev-parse --git-dir)
  • If App-Brief.md is missing at repo root, warn that flows-app-brief should be run first, but continue

Feedback round: look at reviews/code-review/. If it doesn't exist, use feedback-round-1/. Otherwise the next missing round number.

Working directory for all review commands: repo root (the app).

Step 1 — Pull latest checks from cognitedata/builder-skills, then run them

Every review run must start by taking flows-review-checks and code-quality from cognitedata/builder-skills. Do not score from whatever is already in the app’s skills/ folder.

If this workspace already is builder-skills (git remote contains cognitedata/builder-skills): you are in that repo — Read local skills/flows-review-checks/SKILL.md (it loads local code-quality).

Otherwise (reviewing an app): pull those two skills from this repo, then read them:

npx @cognite/cli@latest apps skills pull --skill flows-review-checks
npx @cognite/cli@latest apps skills pull --skill code-quality

If the CLI pull fails, get the same two files from main:

curl -fsSL https://raw.githubusercontent.com/cognitedata/builder-skills/main/skills/flows-review-checks/SKILL.md
curl -fsSL https://raw.githubusercontent.com/cognitedata/builder-skills/main/skills/code-quality/SKILL.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.
