What is yc-jobs-scraper?

A job-listing scraper for Y Combinator's Work at a Startup platform, which lists jobs at startup companies. It collects listings, uses saved login state when needed, and stores identifiers so previously seen jobs are not repeated.

Use it to update a local database of YC startup jobs, retrieve new listings, and keep a deduplicated history of companies and job IDs.

It avoids manually checking many company pages and reduces duplicate results across daily runs. It can fall back to public job pages when its primary data source is unavailable.

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	$0.00090	$0.00723
Opus 5.5	$0.00036	$0.00289
Sonnet 5.5	$0.00018	$0.00145
Haiku 4.5	$0.00009	$0.00072

Security

Grade A, and why

yc-jobs-scraper 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 9d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (scripts/auth.js, scripts/db.js, scripts/export_radar_candidates.js, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

YC Jobs Scraper

This skill provides a robust architecture for scraping jobs from YCombinator and workatastartup.com. It is designed to run automatically, bypass login bottlenecks, and maintain state to never scrape duplicate jobs.

Architecture

The scraper uses a hybrid approach to maximize reliability and minimize bot detection:

Authentication: scripts/auth.js uses Playwright to let a human log in once and saves the session to scripts/state.json.
Database: scripts/db.js uses better-sqlite3 to manage scripts/jobs.db. It tracks every company_slug and job_id ever seen.
Primary Extraction: scripts/scraper.js loads state.json, visits YC query URLs, and extracts company slugs from the hidden Inertia.js data-page JSON payload.
Job Extraction (JSON): It then visits the authenticated company pages (/companies/[slug]) to extract jobs from the backend JSON payload to ensure we get the real job_id for accurate deduplication.
Job Extraction (Fallback): If the JSON extraction fails, it falls back to parsing public HTML job cards from ycombinator.com/companies/[slug]/jobs.

Workflows

1. First-Time Setup

If this is the first time running the scraper in an environment, or if node_modules is missing:

cd @path/scripts
npm install
npx playwright install

2. Authentication (Manual Step)

If scripts/state.json is missing or expired, the scraper will fail. You must instruct the human user to run the authentication script manually:

cd @path/scripts
node auth.js

Tell the user a browser will open, and they must log in. Playwright will automatically save the cookies/tokens to state.json.

3. Running the Daily Scraper

To scrape for new companies and jobs:

cd @path/scripts
node scraper.js

This script will output exactly how many new companies and new jobs were found. Because of jobs.db, running it multiple times consecutively will result in 0 new jobs found.

4. Querying the Database

If you need to analyze the scraped data or view the companies/jobs, you can query scripts/jobs.db directly using better-sqlite3.

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.
