verify

A verification command that chooses focused checks based on the files changed since the last commit. A commit is a saved checkpoint in version control.

In plain words
What is it for?
Use it after edits to run relevant syntax checks, type checks, tests, and related checks for the changed code.
Why use it?
It makes checking changes quicker than a full validation run while still testing the affected parts, such as Ruby, TypeScript, migrations, or seed data.

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 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 yesterday.

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.

The opening of the file, as written. The whole thing — 97 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/verify — Targeted Change Verification

Run focused quality checks based on what actually changed. Faster than validate.sh, more thorough than hooks.

Step 1: Detect Changes

If scope is auto or no argument provided, detect what changed:

# Changed Ruby files (unstaged + staged + untracked)
git diff --name-only HEAD -- '*.rb' 2>/dev/null
git diff --cached --name-only -- '*.rb' 2>/dev/null
git ls-files --others --exclude-standard -- '*.rb' 2>/dev/null

# Changed TypeScript files
git diff --name-only HEAD -- '*.ts' '*.tsx' 2>/dev/null
git diff --cached --name-only -- '*.ts' '*.tsx' 2>/dev/null
git ls-files --others --exclude-standard -- '*.ts' '*.tsx' 2>/dev/null

# Changed migrations and seeds
git diff --name-only HEAD -- 'server/db/migrate/' 2>/dev/null
git diff --name-only HEAD -- 'server/db/seeds/' 2>/dev/null

If a specific scope is given (ruby, typescript, migration, seed), only run that category.

Step 2: Ruby Verification (if .rb files changed)

  1. Syntax check all changed .rb files:
    ruby -c <file>  # for each changed file
    
  2. Find related specs: Map each changed source file to its spec:
    • app/models/foo.rbspec/models/foo_spec.rb
    • app/services/foo.rbspec/services/foo_spec.rb
    • app/controllers/api/v1/foo_controller.rbspec/requests/api/v1/foo_spec.rb or foo_controller_spec.rb
  3. Run related specs (only those that exist):
    cd server && bundle exec rspec <spec-files> --format progress
    

Step 3: TypeScript Verification (if .ts/.tsx files changed)

  1. Type check the full frontend project:
    cd frontend && npx tsc --noEmit
    
  2. Find related tests: Look for *.test.ts or *.test.tsx alongside changed files
  3. Run related tests (if they exist):
    cd frontend && CI=true npx react-scripts test --testPathPattern="<pattern>" --watchAll=false
    

Step 4: Migration Verification (if migration files changed)

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.

verify is a skill published in the GitHub repository nodealchemy/powernode-platform (2 stars, last pushed 3d ago), licensed MIT. It adds 12 tokens to every session and 848 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
