[docs-agent] Weekly skills update 2026-05-06

[JackReacher0807]

Weekly sync from merged docs changes (2026-04-29 → 2026-05-06).

Docs PRs covered

• #1280 — Document supported account types for wallet_requestAccount
• #1234 — Add docs for Solana WebSocket subscriptions and methods
• #1108 — Updating Wallet APIs supported chains page

Skills files updated

• skills/alchemy-api/references/wallets-wallet-apis.md — added an "Account Types (wallet_requestAccount)" table covering all 8 accountType values (sma-b, 7702, la-v2, la-v2-multi-owner, ma-v1-multi-owner, la-v1.1.0, la-v1.0.2, la-v1.0.1) plus routing logic for non-MAv2 migrations. Reflects the docs change that legacy account types are now self-serve, no support ticket needed.
• skills/alchemy-api/references/wallets-supported-chains.md — rewritten from the previous 3-line stub. Now describes the four capability axes the docs table tracks (Bundler, Gas Sponsorship, ERC-20 Gas Payments, BSOs), notes that Solana is sponsorship-only, and notes that BSOs aren't on MegaETH yet. Also picks up the Smart Wallets → Wallet APIs rebrand.
• skills/alchemy-api/references/solana-websocket-subscriptions.md (new) — full reference for Solana PubSub: accountSubscribe, programSubscribe, logsSubscribe, signatureSubscribe, slotSubscribe, rootSubscribe (and matching *Unsubscribe). Covers when-to-use routing, request/notification format, the @solana/web3.js Connection helper mapping, bandwidth-based pricing, and filtering guidance for programSubscribe.
• skills/alchemy-api/references/node-websocket-subscriptions.md — scoped title to "WebSocket Subscriptions (EVM)" and cross-linked the new Solana file so eth_subscribe and Solana PubSub are discoverable from each other.
• skills/alchemy-api/references/solana-overview.md — added the new file to the recommended-reading list.
• skills/alchemy-api/references/skill-map.md — indexed the new file under Solana, refreshed the WebSocket / Wallet APIs / Wallet Supported Chains rows to match the new descriptions.
• skills/alchemy-api/SKILL.md — added an Endpoint Selector row routing "Solana realtime events" → the new file.

Material changes

• New endpoints — 6 Solana PubSub subscribe methods (plus their unsubscribe pairs) gain a dedicated skill reference. Agents can now answer "how do I stream Solana account updates?" without falling back to docs search.
• Corrected API behavior — Wallet APIs wallet_requestAccount now exposes 8 accountType values; the previous skills note implicitly assumed MAv2 only and didn't mention the parameter. Migration guidance updated.
• New supported-chains capability axis — the wallets supported-chains page now tracks Bundler / Gas Sponsorship / ERC-20 Gas Payments / BSOs as four separate columns. The skill now reflects that, including the MegaETH-no-BSO and Solana-sponsorship-only callouts.

Out of scope (non-material this week)

• #1279 (wallet/signer URL slug deduplication) — pure routing fix, no API behavior change.
• #1277 (weekly node upgrades changelog) — playbook excludes changelog-only PRs.
• #1276 (weekly style audit, off-chain → offchain on one Photon page) — single-word style fix.
• #1275 (Daikon Solana OpenRPC sync) — automated method-ref sync, no new methods exposed to skills.
