Eidentic vs Skill Federation

Eidentic and Skill Federation are both agent frameworks tracked by AIDiveForge. Below is a side-by-side comparison of pricing, capabilities, platforms, and ownership — sourced from each tool's live website and verified before publishing.

Eidentic

The SDK centers on a temporal knowledge graph that tracks when facts were true, resolves contradictions, and consolidates between sessions — so the agent sharpens over time rather than accumulating noise. Durable runs, enforced cost ceilings, and CI-gated evals ship as part of the core, not as paid add-ons. The vendor benchmarks report 55.2% on LongMemEval versus 41.0% for full-context stuffing, and claims up to 39× fewer tokens per query. The gap shows up in support and long-running assistant workflows where session history compounds. At v0.1, the ecosystem is early — teams building anything outside the TypeScript path face a hard stop.

Skill Federation

Skill Federation runs locally on your machine and connects to a catalog of over 100,000 vetted skills. When an agent hits a gap, it surfaces matches in milliseconds — each one license-checked, security-scanned, and provenance-tracked — then waits for your approval before installing into .claude/skills/. The benchmark evidence from the vendor is specific: a bare Claude Code agent solves 17.5% of SkillsBench tasks; with Skill Federation retrieving the top match, that climbs to 22.8%, roughly closing 27% of the gap to a hand-crafted ideal skill. The privacy boundary is narrow by design — only an abstract wish crosses the wire, never your code, plan, or outputs. The hard ceiling is integration breadth: Claude Code is supported, with Codex, Cursor, and Gemini listed as coming.

Pros	Temporal knowledge graph tracks fact validity over time and resolves contradictions automatically, which means agents reasoning over months of sessions return accurate historical context instead of hallucinating stale or overwritten facts. Sleep-time consolidation reorganizes memory between sessions without prompt growth, so token costs stay flat as conversation history accumulates — the vendor cites up to 39× fewer tokens per query versus full-context retrieval. Enforced cost ceilings and CI-gated evals ship as core runtime features, which means you catch regressions and runaway spend in the build pipeline instead of discovering them in production billing. Provider-agnostic model and store configuration — OpenAI, Anthropic, Google, Mistral on the model side; SQLite, libSQL, Turso, Postgres, pgvector, Qdrant, LanceDB, Pinecone on the store side — so swapping backends is a constructor argument, not an architectural rewrite. Apache-2.0 license with no paid tier and a self-hosted path, which means the full feature set is available without a commercial dependency or a pricing conversation when you scale.	Two-scanner security vetting at catalog ingestion rather than at install time, so you are never pulling live from an unreviewed repo and your team avoids the malware-by-star-count gamble. License class and provenance shown before every install, which means teams with compliance requirements can audit what skills entered the codebase without reconstructing that history after the fact. Retrieval triggered automatically when the agent hits a gap, so the agent does not require manual skill reminders at the start of every session — a friction point the vendor explicitly benchmarks against. All execution happens on your machine with only an abstract wish transmitted, so codebases, plans, and outputs stay local even when skill search is delegated to an external catalog. Open-source and self-hostable, which means teams that need an air-gapped or fully controlled registry can run their own instance rather than depending on a hosted endpoint.
Cons	The SDK is TypeScript-only. A Python, Go, or Java team hits a dead end at the npm install step — there is no polyglot client, no REST-only path that abstracts the language requirement, and no migration story. Those teams look at LangChain, LlamaIndex, or a framework with a language-agnostic API. At v0.1 with a thin community footprint and docs that the vendor describes as early, debugging non-obvious memory consolidation behavior — why a fact was superseded, why recall missed a session — produces limited guidance. Teams operating at scale with on-call SLA expectations will find the lack of managed support or a commercial support tier a blocking constraint. There is no visual workflow editor or low-code interface. Teams whose agent logic is owned by non-engineers, or whose approval process requires non-technical stakeholders to inspect and modify agent behavior, have no path forward without writing TypeScript — at which point they evaluate tools like Dify or Flowise instead.	Claude Code is the only documented supported integration; teams running Cursor, Codex, or Gemini as their primary agent tool cannot use Skill Federation in its current state — those integrations are listed as forthcoming with no committed timeline on the vendor page. The benchmark ceiling exposes the retrieval model's limit: even the top retrieved skill closes only 27% of the gap to a hand-crafted ideal skill, meaning tasks that require precise, purpose-built skills will still be partially solved at best — teams with narrow, specialized workflows will hit this ceiling faster than teams with general-purpose tasks. No API is available, so teams that want to integrate skill retrieval into a custom agent pipeline or CI workflow cannot call Skill Federation programmatically — teams needing that surface will need to build their own retrieval layer, at which point Skill Federation's catalog is no longer in the loop.

Bottom line

Only Eidentic exposes a public API. Choose based on which difference matters most for your workflow.
