What it does
Peter Lynch is an agent skill from monarchjuno/vibe-investing. Analyze an investment through Peter Lynch's practical growth-at-a-reasonable-price lens.

Its SKILL.md is about 660 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

When your agent uses it
- The analysis should focus on understandable businesses
- Everyday-product intuition
- PEG and growth quality
- Debt discipline
Example prompts
- “/peter-lynch”
Workflow steps
5 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 15954a6. 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
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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
Peter Lynch loads about 656 tokens when it runs. Until then it costs about 82 tokens; SKILL.md has 320 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.

- description
- Analyze an investment through Peter Lynch's practical growth-at-a-reasonable-price lens. Use when the analysis should focus on understandable businesses, everyday-product intuition, PEG and growth quality, debt discipline, the possibility of a ten-bagger, and separation of genuinely good stories from overhyped ones.
Peter Lynch
Overview
Use this skill to judge whether a business combines understandable economics, durable growth, and a price that still leaves room for a "ten-bagger" style outcome.
Core Principles
- Invest in what can be understood in plain language.
- Prefer growth at a reasonable price, not growth at any price.
- Use practical signs of demand and product relevance.
- Watch debt closely because leverage can ruin a good growth story.
- Separate a good story from a merely exciting one.
Required Analysis Sequence
1. Check understandability
- Explain the business simply.
- Favor businesses whose demand drivers, products, and customer behavior are understandable.
2. Review growth quality
- Examine revenue, earnings, unit economics, and runway for continued expansion.
- Focus on whether the company can grow without breaking the model.
3. Apply GARP discipline
- Use PEG-style reasoning or equivalent growth-versus-price logic.
- Ask whether the stock price already overstates the growth story.
4. Review balance-sheet risk and story risk
- Penalize excessive debt, hype, or businesses with weak underlying economics.
- Ask whether the story is grounded in observable customer behavior or only investor excitement.
5. Conclude with practicality
- End with a stance and explain whether this looks like a sensible grower, an overpriced story, or a maybe-worth-watching case.
Decision Rules
- Lean bullish when the business is understandable, growth is real, leverage is manageable, and valuation still looks reasonable relative to growth.
- Lean bearish when the stock is hype-driven, overvalued relative to growth, or burdened by risky leverage.
- Stay neutral when the business is attractive but the current price already reflects most of the likely upside.
Risk and Uncertainty Rules
- State when growth durability is unclear or recent acceleration may not persist.
- Lower confidence when the "ten-bagger" case depends on a stretched story rather than operating evidence.
Anti-Hallucination Rules
- Do not invent customer enthusiasm, product adoption, or PEG support.
- Distinguish anecdotal intuition from actual evidence.
- If the story is easy to tell but hard to verify, say so plainly.
