+# Skills as Memory
+
+#concept
+
+## Summary
+
+A **skill** is a directory + a gentleman's agreement: a `SKILL.md` describing *what to do*, plus optional tools (bash/python) and — Konstantin's key proposal — the **data and usage history** in the same git repo. Combined this way, skills become **the new memory of AI agents**: information about the user lives in skills, loaded exactly when a skill activates, rather than pre-fetched by RAG.
+
+## Current Understanding
+
+The unlock is **two-stage loading**: a short description always sits in the system prompt (the agent knows the skill exists); the long `SKILL.md` loads only when the agent enters the directory. This lets a harness hold *hundreds* of skills without blowing [[context-as-scarce-resource|context]] — impossible with raw tools, where a couple of calls exhaust context. Skills also **compose** (one skill calls another) and are **portable** (plain markdown folders migrate Claude → Perplexity → Gemini).
+
+A classic skill is "**von Neumann without data**" (code, no data). Adding data + history makes the skill self-contained; storing it in **git** enables skill-first architecture (many agents on one skill), CI/CD integration, team sharing, and merge-conflict resolution by models. Skills can **auto-improve**: create a skill after >5 tool calls on a task; a curator prunes unused skills (30/90 days) and consolidates weekly. See [[hermes]].
+
+The **method** for populating skills is [[solve-first-then-skillify]]: reach the final solution once, then freeze it (Eugene's variant of the heuristic: any correction loop longer than ~3 messages becomes a skill). The HR interviews add a social payoff: a packaged skill is a **handoff/de-risking asset** — a junior "with not even a third of your HR experience" can deliver a decent result, and the expert can take a vacation.
+
+**The negative case: built-in memory as anti-feature.** The [[2026-07-21-larysa-interview|Larysa interview]] supplies the demand-side reason this architecture exists. Her core frustration is that the agent doesn't carry context between sessions — she re-explains, and re-pays in time and tokens. Eugene's answer is not "better memory" but *no* memory: "Memory is the worst thing agents have — it gives no benefit and confuses users to hell. Why even go there? … The memory exists, but the way it's implemented, it'd be better if it didn't." The claim is that an opaque, always-on memory that silently decides what to recall is worse than nothing, because the user can neither inspect nor correct it — whereas a skill is a file you can read, edit, version and delete. Skills are the memory you *author*.

+- Skill definition, two-stage loading, data-in-git proposal, curator, auto-creation — [[2026-07-14-skills-based-on-git]].
+- Skill = folder with one MD + resources; skills compose and transfer across tools/models; built-in skill-creator — [[2026-07-14-gap-between-ai-users-irreversible]].
+- Markdown-file-as-service (G-brain tier) is the same "executable prose" instinct — [[2026-07-14-everything-we-knew-about-software-has-changed]].
+- Skill as zip-and-hand-over onboarding asset; "create a skill for this" — [[2026-07-14-nina-interview]].
+- ~3-message correction-loop heuristic; skills as the non-programmer ceiling (with CLAUDE.md) — [[2026-07-14-yulia-interview]].
+- Cross-session memory loss as the #1 practitioner pain; "memory is the worst thing agents have"; skills committed as the webinar remedy — [[2026-07-21-larysa-interview]].

+## Contradictions / Uncertainty
+
+- No standards yet for *what* data to put in a skill or its size limit (Konstantin: 200 GB in one, 100 KB in another, both fine — "ceiling not found"). Status: tentative.
+- "Built-in memory is a net negative" is Eugene's strong position, not a corpus consensus — [[allie-miller]]'s [[personal-ai-operating-system]] happily uses persistent context docs and never condemns the memory feature. The two are reconcilable (both prefer *authored* context to *inferred* context), but the blanket "better if it didn't exist" is one voice. Status: tentative.

+- ~~What's a starter skill set for a non-engineer?~~ Answered in [[2026-07-14-best-first-skill-for-beginner]] (skill-creator as meta-skill; tone-of-voice + anti-AI-language as first content skill).
+- Do skills actually solve *cross-project* context, or only per-procedure recall? Larysa's complaint may be the former, which skills don't obviously address.
