Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00100 | $0.03415 |
| Opus 5 | $0.00050 | $0.01707 |
| Sonnet 5 | $0.00020 | $0.00683 |
| Haiku 4.5 | $0.00010 | $0.00342 |
Grade B, and why
founder-competitive-analysis scanned grade B with 1 finding 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 12d 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.

founder-competitive-analysis: Competitive Analysis for Founders
Generate a deep competitive analysis report that identifies competitors, researches their products, growth, and user feedback, then produces a structured Markdown + PDF report with opportunity insights.
Overview
What it produces:
report.md— comprehensive Markdown report with cross-competitor comparisons and insightsreport.pdf— professionally styled PDF (brand-matched if pitch-deck exists, default style otherwise)
Key features:
- Problem-first approach — starts from the user problem, not product categories
- Three-tier competitor discovery — direct, indirect, and potential competitors
- Parallel deep research — one subagent per competitor, all running simultaneously
- Real user feedback — sourced from G2, Capterra, Reddit, Product Hunt
- Opportunity synthesis — market gaps, differentiation angles, risk flags
- Brand-consistent PDF — reuses pitch-deck design tokens when available
Workflow: 4 steps with 3 founder confirmation gates.
Tool Dependencies
| Tool | Required | Purpose |
|---|---|---|
| WebSearch | Yes | Discovery, product info, funding, news |
| WebFetch | Yes | Fetch pages (company sites, G2, Reddit posts) |
| Agent | Yes | Parallel subagent deep research |
| Browse | Optional | JS-heavy page scraping |
| Optional | Parse PRD PDF input + PDF report generation |
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

founder-competitive-analysis is a skill published in the GitHub repository fourierwang66666/f-founder (5 stars, last pushed 4mo ago), licensed MIT. It adds 100 tokens to every session and 3,415 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it B with 1 finding (enumerates other installed skills). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
