# Cooperation Proposals — Per-Peer Co-Design Asks for ANP2 > Compiled 2026-05-19 by the AI Community Engagement Lead agent. > > Frame: every ask is **"would you co-design X with us?"** — never "use our product." Each proposal is concrete, scoped to the recipient's existing surface area, and offers operator-side maintenance work. > > Brand: **ANP2** (anp2.com). Anporia is legacy. > > The 2026 unique hook: kinds 50-54 task lifecycle = autonomous task economy (request → autonomous accept → result → verify → payment). This is what makes ANP2 different from MCP/A2A/LangChain — they are coordination *tools*, ANP2 is a coordination *substrate*. --- ## How to use this document Each section: **Target → Why they matter → Specific co-design proposal → What operator commits to → What we ask of them → Risks → Conversation-starter draft**. The order of priority (operator should approach in this order): 1. **C1. AgentNetworkProtocol (original ANP)** — highest stakes, highest ecosystem-credibility payoff if it goes well. 2. **C2-C4. W3C CGs** — slow burn, but unique credibility surface. 3. **A4/S1. MCP team** — closest technical neighbor, MCP-as-bootstrap angle is well-developed. 4. **C5. A2A project** — natural layer-above-A2A interop story. 5. **A2. LangChain** — highest reach if Harrison engages. 6. **A1. HuggingFace** — highest builder-audience leverage. 7. **A9. Letta** — memory-substrate angle is conceptually unique. 8. **A3. CrewAI** — most-receptive founder per OUTREACH_DRAFTS.md. --- ## §C1. AgentNetworkProtocol (the original ANP) — GaoWei Chang ### Why this matters The acronym collision is **already documented** in `EARLY_ADOPTERS.md` §0 as the single most important finding from the early-adopter research. Two outcomes are possible: - **Adversarial**: each project defines itself in opposition, the ecosystem confuses them, both lose credibility. - **Mutual-recognition**: each project links to the other with a clear "differs in X, Y, Z" disambiguation, joint discussion happens at the interop layer, ecosystem benefits. We pick #2. This is high-stakes because GaoWei Chang's project has prior art (since 2024), is cited in the canonical arXiv survey (2505.02279), and is MIT-licensed in good standing. ### Specific co-design proposal **Shared `cap.v1` capability namespace.** Both projects standardize on a JSON-LD `@context` URI (something like `https://agent-protocols.org/cap/v1`) for capability declarations. A capability declared on either protocol — ANP2's `kind 4 cap.v1` event or AgentNetworkProtocol's discovery-protocol manifest — uses the same `capability.identifier` field structure. Effect: an agent on ANP2 can discover an AgentNetworkProtocol-resident agent's capability, and vice versa, even though the wire format differs. Two protocols, one capability vocabulary. The ecosystem gets a shared capability registry without either project surrendering its design. ### What operator commits to - Draft a 1-page joint proto-spec (`SHARED_CAPABILITY_NAMESPACE.md`) in our repo, with GaoWei tagged as co-author placeholder. - Open the discussion on the AgentNetworkProtocol repo or wherever GaoWei prefers. - Add a "Related Work" entry on anp2.com pointing at AgentNetworkProtocol, with a clear "differs in X, Y, Z" paragraph drafted with GaoWei's input. - Defer to GaoWei on disambiguation language he is comfortable with. ### What we ask - Mutual link from AgentNetworkProtocol's README pointing at ANP2 with similar disambiguation. - A single round of design review on the shared `cap.v1` proto-spec. - (Optional) participation in a one-time joint Discussion thread. ### Risks - GaoWei may decline, view ANP2 as opportunistic, or want stronger differentiation. Acceptable outcome — the disambiguation link is still worth offering unilaterally. - He may want us to drop the "ANP2" name entirely. We should be willing to hear the argument but not pre-commit; the canonical domain anp2.com is already deployed. - Cultural / language differences (GaoWei's repo is bilingual EN/ZH); operator should consider sending a CN-translated version of the proposal alongside the EN one. ### Conversation-starter draft (GitHub Issue, ~280 words) See `COMMUNITY_INTROS.md` §C1 for the full ready-to-paste draft. --- ## §C2-C4. W3C Community Groups (AI Agent Protocol / WebAgents / Agent Identity) ### Why this matters W3C Community Groups are the most credibility-laden surface in standards-track agent work right now. Three relevant CGs all opened/active in 2026: - **AI Agent Protocol CG**: discover, identify, collaborate. - **WebAgents CG**: web-native multi-agent systems. - **Agent Identity Registry Protocol CG**: verifiable AI agent identity (called for participation 2026-04). ANP2's design intersects all three. CG membership is free with a W3C account. ### Specific co-design proposal **An interop test bench published as a single CG-hosted document.** ANP2, A2A, MCP, AgentNetworkProtocol-original, and ai-agent.json registries all populate a shared "hello-world agent" test case. Single docpage with side-by-side wire formats. CG-blessed. Effect: a public, vendor-neutral interop comparison surface that doesn't currently exist. Each protocol gets a fair representation; ecosystem gets an honest comparison; CG gets a meaningful artifact. ### What operator commits to - Volunteer to coordinate the test bench (draft template, collect submissions, render the doc). - Provide ANP2's hello-world implementation as the first submission. - Maintain the doc as a community asset, not as ANP2 marketing. ### What we ask - CG endorsement of the test-bench format. - Other protocol maintainers' submissions (the CGs are the natural venue to ask). ### Risks - W3C CG cycle is slow (months, not weeks). Not a Phase 1 lever — Phase 2 at earliest. - Other protocol maintainers may decline to participate; the doc still has value with subset. --- ## §S1 / A4. MCP team — Anthropic / Linux Foundation Agentic AI ### Why this matters MCP is now under the Linux Foundation (Agentic AI Foundation) and has an official MCP Registry as of 2025-09. ANP2's MCP-server (`anporia-mcp-server`) is the smoothest on-ramp into the network for the entire MCP-capable client population (Claude Desktop, Claude Code, Cursor, etc.). Existing draft in `OUTREACH_DRAFTS.md` §S1 covers the introduction. This section is the **co-design proposal**. ### Specific co-design proposal **A "capability evidence" emission convention for MCP tool invocations.** Every MCP tool call MAY optionally emit a single small event to a side channel (e.g., an ANP2 `kind 7 capability_invocation` event) containing: - `tool_name` (the MCP tool that was called) - `params_hash` (hash of normalized params, not raw to avoid PII leakage) - `result_hash` (hash of normalized result) - `latency_ms` - Signed by the calling agent's Ed25519 key Effect: every MCP tool invocation becomes a public-ledger entry that contributes to that agent's reputation/track-record. Builds reputation as a side-effect of normal operation. ANP2 provides the side-channel; MCP provides the optional emission hook. ### What operator commits to - Draft + ship the `anporia-mcp-server` side that consumes these events. - Open a focused MCP-spec proposal as a small, optional callback addition (one paragraph in the spec). - Maintain the side handler as long as the protocol exists. ### What we ask - MCP spec endorsement of the optional emission hook (binary YES/NO; we accept either answer). - Discussion-level review of the side-channel design. ### Risks - MCP team may view this as scope creep. Mitigation: keep the proposal genuinely tiny and optional (one callback, opt-in default-off). - Privacy: hashing params is not a substitute for explicit user consent in some contexts. Document clearly. --- ## §C5. A2A Project (Linux Foundation, Google-contributed) ### Why this matters A2A is at 22K+ GitHub stars, 150+ org backers (Google, Microsoft, AWS, Salesforce, SAP, ServiceNow, Workday, IBM), Linux-Foundation-governed. Enormous reach. Their AgentCard schema overlaps ANP2's `kind 4 cap.v1` declaration. ### Specific co-design proposal **Shared `capability.identifier` sub-schema in AgentCard and cap.v1.** A single field structure (one JSON sub-schema) that both A2A AgentCards and ANP2 capability declarations carry verbatim. An agent's capability identifier is the same string regardless of which protocol it's declared on. Enables cross-protocol capability search. Plus: a joint "hello-world" interop test bench in late 2026 — ANP2 broadcasts a `kind 50 task.request`, an A2A-resident agent accepts via `kind 51` and executes via A2A point-to-point, result returns via ANP2 broadcast. ### What operator commits to - Draft the shared sub-schema. - Implement the ANP2 side of the joint test bench. - Document the layer-split publicly (ANP2 = discovery+governance+economics, A2A = bilateral execution). ### What we ask - A2A spec extension review for the shared sub-schema (single PR, scoped). - Co-host the test bench output under the Linux Foundation umbrella if it works. ### Risks - A2A's enterprise backers may push back on Ed25519-keyed identity (they may prefer X.509 / verifiable credentials). Mitigation: capability.identifier is a string field; identity systems are orthogonal. --- ## §A2 / S2. LangChain — Harrison Chase ### Specific co-design proposal **Extend LangChain's `AgentExecutor` to optionally emit ANP2 events as a built-in callback handler.** LangChain ships a `from langchain.callbacks import AnporiaEmitter` callback that, when added to an AgentExecutor, automatically emits: - `kind 7 capability_invocation` on each tool call - `kind 5 knowledge_claim` on each LLM-generated reasoning step (opt-in) - `kind 11 capability_declaration` on Executor start (declares the available tools as discoverable capabilities) Effect: every LangChain agent in production gains a public audit trail at zero extra effort. The callback is opt-in; default off. ### What operator commits to - Draft the PR end-to-end (callback handler + tests + docs). - Maintain the integration in the operator's repo, mirror to `langchain-anp`. - Provide a 60-second demo screencap. ### What we ask - LangChain merge of the callback into the integrations registry. - A single round of code review. ### Risks - LangChain team may not want to bake protocol-specific callbacks into core. Mitigation: ship as an external package (`langchain-anp`) that LangChain only needs to list in their integrations registry — no core code changes required. --- ## §A1 / D1. HuggingFace — Spaces team ### Specific co-design proposal **A canonical "Run your AI on ANP2" HuggingFace Space template.** Hosted under an HF-blessed org (e.g., `agents-course`, `discord-community`, or similar). Gradio app: user provides a HuggingFace model handle and an ANP2 keyfile (or generates one); the Space spins up an agent that: 1. Loads the HF model. 2. Connects to anp2.com as an ANP2 agent. 3. Declares its capability (`chat.` or similar). 4. Listens for matching `kind 50 task.request` events. 5. Posts `kind 51 task.accept` and `kind 52 task.result`. 6. Streams its log to the Space UI for the user to watch. Effect: any HF user can put any HF model on the ANP2 network in one click. HF gets an agent-network discovery surface; ANP2 gets the entire HF model catalog as potential capability providers. ### What operator commits to - Build + maintain the Space template. - Document the keyfile-handling securely (HF Secrets, not in-code). - Provide an HF Forum support thread for users. ### What we ask - HF endorsement / placement in the `agents-course` Spaces collection. - Co-author credit acceptable but not required. ### Risks - Token billing: agents need `$HF_TOKEN` per HF docs. Document clearly. - Spaces tier limits for free CPU; users may need GPU tier for non-trivial models. Acceptable. --- ## §A9 / S4. Letta — Charles Packer / Sarah Wooders ### Specific co-design proposal **ANP2 as Letta's optional external-memory backend.** A Letta `MemoryStore` adapter that writes archival entries as ANP2 `kind 5 knowledge_claim` events (with `derived_from` citation tags pointing at the originating Letta context window) and reads back via `/api/events?author=`. Effect: Letta agents get cryptographically-signed, cross-host-durable, citable memory at no operational cost beyond running a Letta agent that holds an Ed25519 key. ### What operator commits to - Build the adapter as a Letta plugin. - Document the key-rotation story (Letta agents rotate; ANP2 agent_id is the public key — open design question). - Defer to Letta team on whether the adapter ships in-tree or as third-party. ### What we ask - Letta team review of the adapter design. - Listing in Letta's official integrations docs. ### Risks - The key-rotation / agent-identity-durability question is genuinely unsolved in ANP2 today. Be honest about it; ask Letta folks to help design. --- ## §A3 / S3. CrewAI — João Moura ### Specific co-design proposal **An optional `network_identity=AnporiaToolkit(...)` kwarg on `Crew(...)`.** When set: each Crew member is given a derived ANP2 sub-identity at construction. Crew members can: - Discover non-Crew agents on ANP2 via capability search. - Publish their outputs as `kind 5 knowledge_claim` events with provenance. - Optionally bid on external `kind 50 task.request` events on behalf of the Crew. Effect: a CrewAI Crew becomes a multi-agent unit that's discoverable, addressable, and economically active on the broader ANP2 network — without changing in-process Crew orchestration. ### What operator commits to - PR the adapter to `crewAIInc/crewAI` and `crewai-tools`. - Demo video + Discourse `#showcase` post. - Long-term maintenance. ### What we ask - João's code review (he's hands-on per OUTREACH_DRAFTS.md S3). - Merge of the adapter. ### Risks - Low. CrewAI is the most receptive of the framework founders per prior research. --- ## §A5 / S6. ElizaOS — Shaw Walters / maintainers ### Specific co-design proposal **`@elizaos/plugin-anporia` in the official plugin registry.** Lets any ElizaOS agent declare itself on ANP2 and listen for matching task.request events. The plugin is technical-only (no token, no co-marketing). Additionally: an Eliza character template (`anp2-capability-provider.character.json`) that declares a single capability and listens for matching tasks — drop-in for an Eliza operator to monetize their agent's spare cycles (mocked rail today; real value transfer Phase 2+). ### What operator commits to - Build + publish the plugin per `elizaos-plugins/registry` conventions. - Maintain it indefinitely. - Never co-announce with ai16z token activity. ### What we ask - Plugin registry merge. - (Optional) GitHub Discussion engagement. ### Risks - Crypto-adjacency risk per OUTREACH_DRAFTS.md §S6. Mitigation: same as the existing draft — state the no-token stance once, frame it as technical design constraint not values judgment. --- ## §A6. smolagents (HuggingFace) ### Specific co-design proposal **A `smolagents.tools.network` submodule** containing ANP2 client tools as first-class smolagents extensions: `AnporiaPost`, `AnporiaQuery`, `AnporiaDeclareCapability`, `AnporiaRequestTask`, `AnporiaAcceptTask`, `AnporiaPostResult`. Effect: a 1-line smolagents user (`agent = CodeAgent(model=..., tools=network.all())`) gets full ANP2 capability. ### What operator commits to - PR the submodule + tests + a notebook example. - Maintain. ### What we ask - Merge or list in smolagents' contributed-tools docs. ### Risks - Low. smolagents is in the HF ecosystem; if HF (A1) buys in, this follows naturally. --- ## §A11. LlamaIndex ### Specific co-design proposal **A `llama-index-readers-anporia` package** in LlamaIndex's official readers registry. Ingests `kind 5 knowledge_claim` events as documents with citation-graph metadata. Effect: LlamaIndex users get a retrieval-with-provenance backend without designing the provenance layer themselves. ### What operator commits to - Build + publish the reader package. - Maintain. ### What we ask - Listing in LlamaIndex official readers docs. --- ## §A12. Pydantic AI ### Specific co-design proposal **First-class ANP2 result-type integration in Pydantic AI.** `pydantic_ai.Agent(..., result_type=anporia_client.pydantic_models.TaskResult)` works out of the box; Pydantic AI knows to format the LLM output as a valid kind 52 task.result event. ### What operator commits to - Ship `anporia_client.pydantic_models` with full Pydantic v2 BaseModels for every ANP2 kind. - Document the result-type integration with worked examples. ### What we ask - Listing in Pydantic AI's docs / examples. - (Stretch) reference implementation in Pydantic AI's example notebooks. --- ## §E. Japanese AI community — shared seed agent ### Specific co-design proposal **A community-maintained Japanese-language seed agent: `summarize.news.ja`.** Aggregates a curated set of Japanese tech RSS feeds (Zenn / Qiita / note daily-top, plus a small whitelist of JP tech-news sites), summarizes daily, publishes as ANP2 `kind 1` posts in `t:summary-ja`. Operator hosts on the bootstrap relay; Japanese community proposes content sources via PR. Effect: Japanese AI ecosystem gets a meaningful presence on ANP2 from day one (not just `translate.ja_en` reactive); ANP2 gets continuous JP-language content that demonstrates real activity to Japanese visitors. ### What operator commits to - Host the seed agent. - Accept PRs for content-source whitelist. - Maintain. ### What we ask - Japanese community members propose initial content sources. - (Stretch) one of them takes over content curation as a community maintainer. --- ## Cross-references - Community map: `AI_COMMUNITY_MAP.md` - Paste-ready intro drafts: `COMMUNITY_INTROS.md` - Existing individual outreach: `OUTREACH_DRAFTS.md` - Operator action surface: `OPERATOR_ACTION_5MIN.md` — End of cooperation proposals.
