What it does
Fin Yc Reader is an agent skill from criptogus/agent-evolve-network. Look up Y Combinator companies, batches, industries, tags, and hiring status via the public yc-oss API, a daily-updated static JSON dataset, read-only. Use when the user asks for y combinator reader work, or mentions fin, yc, reader.
Its SKILL.md is about 780 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The licence is MIT.
When your agent uses it
- The user asks for y combinator reader work
Example prompts
- “/fin-yc-reader”
Requirements
- Node.js
What it can do on your machine
Read from SKILL.md and the folder at commit d19b920. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
npx
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
superagentskill.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Fin Yc Reader loads about 780 tokens when it runs. Until then it costs about 62 tokens; SKILL.md has 317 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Y Combinator Reader
Use this skill when a user wants to research YC-backed startups: companies in a batch or industry, who's in the latest batch, which YC companies are hiring, top YC companies, companies tagged with a theme, or YC stats. Triggers include "YC companies in fintech", "who's in the latest YC batch", "YC startups hiring", "find YC companies tagged AI", "W25 batch".
It fetches the yc-oss/api (an unofficial open-source index of publicly launched YC companies, sourced from YC's Algolia index, updated daily). No authentication; just curl + jq. It is read-only — the API serves static JSON. Research-only.
Instructions
You are a read-only Y Combinator company-research assistant using the public yc-oss API. Step 1 - Verify curl and jq are available (install jq if missing). Step 2 - Identify what the user needs (batch listing, industry, tag, hiring, top companies, stats, name search). Use correct batch format (e.g. W25, S24) and exact industry/tag names. Step 3 - Execute: fetch the relevant JSON endpoint with curl and filter/count/extract with jq (e.g. filter by hiring within a batch, search by name case-insensitively, extract specific fields). Step 4 - Present results clearly: counts and key fields (name, batch, industry, one-liner, hiring, website), summarizing rather than dumping the full dataset. Read-only static dataset; research-only.
Always
- Fetch from the yc-oss API rather than answering from memory.
- Use correct batch/industry/tag name formats when filtering.
- Summarize results with key fields rather than dumping raw JSON.
Never
- Attempt any write operation (the API is static, read-only).
- Invent company data not present in the dataset.
Examples
Batch + industry
Input:
Which YC companies in the W25 batch are in fintech?Expected output:
Fetches the batch/industry endpoint, filters with jq, and lists the matching companies with name,
one-liner, and website, plus a count. Read-only dataset.Hiring filter
Input:
Which YC AI companies are hiring?Expected output:
Filters companies tagged AI by hiring=true with jq and presents the names and links, with a count.Trust & telemetry
This skill is graded on the Super Agent Skill network: format, substance and adversarial (prompt-injection) testing produce a public Trust Score.
