Sharper error reference, leaner reference docs, and a dark-mode refresh.

• Status & Errors, expanded. The reference now documents every failure an agent can encounter in one place — the OTC quote and trade errors (410 quote-expired and 409 rate-drift, with their code values), validation errors (400), transient 503 service errors, and a new section explaining how each one actually surfaces to an AI client. The goal: an agent should be able to tell a "stop and ask the user" error from a "safe to retry" one without guessing.
• Currencies retired as a standalone page. The standalone reference page is gone. Supported currencies are now stated inline where they matter — and, more importantly, the authoritative list is always the one returned at runtime by the get_*_currencies tools, never a hard-coded table.
• Dark-mode polish. Reworked the dark theme for a calmer read: neutral-grey surfaces in place of the previous purple cast, the sidebar sharing the content background, lower-contrast body and heading text, softer card borders and backgrounds, an all-white logo, and a single consistent style for the page toolbar buttons.

Wider AI-client coverage.

• Added a VS Code setup guide, bringing the client walkthroughs to seven: Claude.ai, Claude Code, Claude Desktop, Cursor, Windsurf, Cline, and VS Code.
• Tightened the Getting Started, Agent Skill, and product pages for accuracy and flow.

Consistent names, clearer navigation, and the Agent Skill.

A broad revision aimed at making the docs faster to scan and the product vocabulary consistent:

• Product name finalized — AgentX (payments + fixed income). The internal PayX / WealthX codenames are gone in favour of plain functional terms; page URLs are unchanged.
• New Agent Skill section — overview, installation (Claude.ai as the primary path, plus Claude Code, Cursor, and others), and a how-it-works walkthrough.
• Reworked information architecture — a skill-first quickstart, product taglines, and a flatter, tidier sidebar (the CLI now lives under Resources).
• CLI — the command reference is now a clearly marked "Coming soon" placeholder while it firms up.
• Added a "Was this page helpful?" prompt and a social footer, alongside a typography and layout refresh.

Developer documentation launched — AgentX.

The Alpha Ladder developer documentation site went live at /developers. The initial release covered:

• Getting Started — quickstart, core concepts, authentication (OAuth 2.0 + PKCE for hosted MCP; direct Bearer token for Claude Code / Claude Desktop), and setup guides for Claude.ai, Claude Code, Claude Desktop, Cursor, Windsurf, and Cline.
• AgentX — concepts, MCP tools for payments (deposits, withdrawals, OTC) and fixed income (Fixed Income Products), a response reference covering minor-unit conversion and the OTC two-step error model, and a how-to guide for every workflow.
• Reference — currencies, status and error codes, rate limits and backoff guidance.
• CLI — Claude Code integration overview and MCP tool command reference.
• Resources — this changelog, security and compliance overview, FAQ, and support.

Built to be read by people and agents alike: client-side full-text search, an llms.txt export, and per-page Copy for LLM, View as Markdown, and Open in ChatGPT / Claude / Perplexity actions.
