Summary

Phase 3 sprint S24 — closes #179, #180, #181, #182, #183.

• [F3] #66 — Memory graph (non-linear) #179 Graph memory — `createInMemoryGraph` in `@agentskit/memory`: typed knowledge graph (nodes + edges + BFS neighbors + cascading deletes) against a `GraphMemory` contract that Neo4j / Memgraph / Neptune can back.
• [F3] #67 — Personalization layer (persisted profile) #180 Personalization — `createInMemoryPersonalization` + `renderProfileContext` in `@agentskit/memory`. Per-subject trait profile; `get`/`set`/`merge`/`delete`; safe system-prompt renderer.
• [F3] #68 — Doc loaders (URL, PDF, GitHub, Notion, Confluence, Drive) #181 Document loaders — six loaders in `@agentskit/rag`: `loadUrl`, `loadGitHubFile`, `loadGitHubTree`, `loadNotionPage`, `loadConfluencePage`, `loadGoogleDriveFile`, `loadPdf` (BYO parser). All accept a custom `fetch`.
• [F3] #69 — Skill marketplace with versioning #182 Skill marketplace — `createSkillRegistry` + semver helpers (`parseSemver`, `compareSemver`, `matchesRange`) in `@agentskit/skills`. Publish, list by publisher/tag, install by range.
• [F3] #70 — Ready-made skills (code review, SQL gen, etc.) #183 Ready-made skills — four new skills: `codeReviewer`, `sqlGen`, `dataAnalyst`, `translator`.

~65 new tests.

Changeset

`.changeset/phase3-s24-graph-personalization-loaders-skills.md` — minor bumps on `@agentskit/memory`, `@agentskit/rag`, `@agentskit/skills`.

Out of scope (deferred)

• Native Neo4j / Memgraph / Neptune driver adapters — same contract; follow-up sprint.
• PDF / DOCX / HTML→Markdown conversion baked in — BYO parser now.

Test plan

• memory / rag / skills test suites pass
• `pnpm -r lint` clean
• `pnpm --filter @agentskit/docs-next lint`
