verify-changes

verify-changes is a skill for Claude Code, Codex from foru17/neko-master. It costs 47 tokens per session (563 once invoked), scanned A, original, MIT.

A repository-specific guide for checking code changes before committing or opening a pull request. It selects checks based on which part of the project was edited.

In plain words
What is it for?
Running the relevant type checks, tests, linting, and production build for the backend, frontend, shared package, or Go agent.
Why use it?
It helps avoid choosing incomplete or unnecessarily large checks after a change.

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

verify-changes 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 4d 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.

What it actually says

Verify Changes

Run the smallest check set that covers what you touched. All commands run from the repo root unless noted.

By touched area

apps/collector (backend)

pnpm --filter @neko-master/collector exec tsc --noEmit
pnpm --filter @neko-master/collector test

Single test file / case (much faster while iterating):

pnpm --filter @neko-master/collector test -- src/modules/auth/auth.service.test.ts
pnpm --filter @neko-master/collector test -- -t "should validate token format"

Lint (CI-relevant; console.log is forbidden in collector source — use console.info/warn/error):

pnpm --filter @neko-master/collector lint

apps/web (frontend)

pnpm --filter @neko-master/web exec tsc --noEmit
pnpm --filter @neko-master/web lint

For production-impacting changes (new routes, error boundaries, next.config, i18n files) also run the full build — it catches what tsc alone misses:

pnpm --filter @neko-master/web exec next build

packages/shared

Shared types are consumed by both apps — verify both compile:

pnpm --filter @neko-master/shared build
pnpm --filter @neko-master/collector exec tsc --noEmit
pnpm --filter @neko-master/web exec tsc --noEmit

apps/agent (Go probe)

cd apps/agent
go vet ./... && go build ./... && go test ./...
sh -n nekoagent && sh -n install.sh

Checklist before commit

  • Checks above pass for every touched area
  • New behavior has a test (collector uses Vitest; see src/__tests__/helpers.ts for createTestDatabase() / createTestBackend())
  • UI changes: both locales translated and dark mode checked (see the ui-conventions skill)
  • DB writes/schema touched: run the add-stats-dimension / db-conventions checklists

Note: .husky/pre-push runs collector tsc --noEmit + web build when pushing to main — running them yourself first avoids a slow failed push.

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.
