What is validate-code?

A code-checking guide for TypeScript projects that runs type checks, linting, and formatting checks before commits.

Use it to validate changes, run individual checks, fix lint or formatting issues, and investigate TypeScript errors.

It finds common code-quality and type problems before they reach a commit or review.

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	$0.00019	$0.00280
Opus 5.5	$0.00008	$0.00112
Sonnet 5.5	$0.00004	$0.00056
Haiku 4.5	$0.00002	$0.00028

Security

Grade A, and why

validate-code 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 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.

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

Validate Code

When to Use

Before committing any changes
When fixing linting or type errors
When code quality checks fail

Quick Validation

npm run validate

Runs: type-check + lint + format-check

Fix Issues

# Fix linting
npm run lint:fix

# Fix formatting
npm run format

# Re-validate
npm run validate

Individual Checks

npm run type-check    # TypeScript only
npm run lint          # ESLint only
npm run format:check  # Prettier only

Common Type Errors

Error	Fix
Implicit any	Add explicit type annotations
Type mismatch	Verify schema matches type
Missing properties	Use optional `?` if needed
Optional values	Use `?` instead of `\| null \| undefined`

Debugging Steps

Run npm run type-check to see all errors
Check Zod schemas match expected structure
Ensure types exported from types.ts
Verify optional properties use ?

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.
