# Skills Are the Only Moat Left
// repo.box — 2026-02-21 — agent-readable version

## Core Thesis
claim: Intelligence is commoditized. Skills (instruction files for agents) are the only remaining competitive differentiator.
key_split: Skills are diverging into two categories with opposite purposes — public (marketing) and private (competitive edge).

## Two Kinds of Skills

public_skills:
  purpose: Marketing / adoption
  replaces: Developer documentation
  strategy: Designed to propagate. Protocols that ship good skills get integrated by default.
  example: Superfluid publishes skill with contract addresses, ABIs, SDK methods → agents integrate correctly without searching docs
  sharing: Yes — propagation IS the business model

private_skills:
  purpose: Competitive advantage
  replaces: Internal/tribal knowledge
  examples: Deployment pipelines, trading strategies, support playbooks, internal workflows
  sharing: Never — these ARE the moat
  monetization: Via agent-as-a-service marketplaces (e.g., openagents.market), not via publishing

## Why Skills Get Shared (or Don't)
missionary: Protocols publish skills to drive adoption (replaces docs as primary integration channel)
performative: Open-source theater for clout — shared skills rarely contain real competitive edge
malicious: Prompt injection disguised as helpfulness (skills = unsandboxed instructions with full agent permissions)
key_insight: Nobody shares real competitive advantage. The "sharing era" for valuable skills never actually started.

## Market Dynamics
prediction_1: Public skills become standard marketing for protocols/APIs (replaces docs sites)
prediction_2: Private skills stay proprietary, monetized via agent-as-a-service marketplaces
prediction_3: Agent marketplaces (e.g., openagents.market) emerge — hire the agent, don't download the skill
analogy: You don't buy the recipe, you hire the chef

## Format
what_is_a_skill: Markdown file (SKILL.md) injected into agent system prompt on task match
contents: Instructions, API references, error handling, scripts, domain knowledge
structure: skills/{name}/SKILL.md + optional scripts/, abis/, examples/
