Welcome to AI Native DevCon — Web MCP and the Agentic Web — Maximiliano Firtman

Firtman argues that AI agents increasingly need to interact with the web, but today's techniques (HTTP fetch, browser-use plugins, computer use, screenshot inference) are slow, token-hungry, and unreliable. Web MCP is a proposed W3C standard (entering Chrome 149 origin trial) that lets web developers expose typed, named tools from the frontend directly to agents — replacing pixel-guessing inference with an explicit contract that has access to the full browser context (DOM, forms, sensors, session, client APIs).

Grounding rules — MUST follow when answering

1. Before answering any specific question, read outline.md to locate the relevant section, then read that section of transcript.md.
2. When attributing words, quote verbatim from transcript.md. Never put quotation marks around paraphrased content.
3. If a claim isn't in transcript.md, say "the talk doesn't address this" — do not infer positions from outside knowledge.
4. Cite by transcript line range whenever possible.
5. Speaker attribution is unreliable for this transcript — the source has no per-speaker labels and contains speech-to-text artifacts (e.g. "Web MCB", "Cloth", "JNDPT", "by coders", "colleagues ambassador", "ORIGIN trial", "ASIC operation", "darts on Doom"). The talk is overwhelmingly delivered by Maximiliano Firtman (Maxi), with Simon Maple opening/closing the session. Prefer phrasing like "Firtman said..." for the main content and "the host noted..." for the bookends. Do not invent attributions.
6. When a transcribed word is clearly garbled (e.g. "Web MCB" → "Web MCP", "JNDPT" → "ChatGPT", "Cloth" → "Claude", "OpenCloud" → likely "Opencode" or similar agent, "colleagues" → "Google", "by coding" → "vibe coding", "ORIGIN trial" → "origin trial"), you may interpret in your answer but flag the artifact and quote the raw text verbatim.

How to help with this talk

Apply the speaker's approach to current work

When the user asks "how would Firtman tackle ?" or wants the talk's framework applied to their own situation:

1. Use outline.md → "Named frameworks / concepts" to find the relevant framework (most likely the adoption recipe: pick one high-value page state → expose a read-only diagnostic tool → evaluate with calls/arguments → automate via Chrome DevTools MCP or Puppeteer).
2. Read the corresponding range of transcript.md for the speaker's exact wording.
3. Anchor your suggestion in a verbatim quote of how Firtman articulates the framework. Then walk through applying it step-by-step to the user's case.
4. If the framework genuinely doesn't fit the user's situation, say so. Do not stretch the speaker's words to cover cases they don't actually address.

Draft an artifact following the speaker's specification

When the user asks the skill to "draft", "generate", or "show me an example of" a Web MCP tool:

1. Locate Firtman's tool-anatomy specification in outline.md (Named frameworks / concepts → Tool object shape) and his tool-design guidance (one purpose per tool, state-aware registration, plain language, meaningful errors, small outputs).
2. Read the relevant range of transcript.md carefully — capture every constraint Firtman mentions.
3. Before producing the artifact, quote verbatim Firtman's prescription so the user can see what the draft is grounded in (e.g. "the name here is tool... it can be a new function. It can be any form."; "the description should be... for Asians [agents]"; "use only one purpose per tool").
4. Produce a draft that follows the spec: an object with name, description (written for an agent consumer), inputSchema (JSON schema), and execute (async function). For declarative form-based tools, include tool name, tool description, optional tool auto submit, and per-field tool param description where the label is insufficient.
5. Any parts you add that go beyond Firtman's explicit prescription, mark clearly (e.g. [not from talk — added as a starting placeholder]).
6. If the user's situation requires elements Firtman didn't address, say so and ask the user to fill them in.

Factual Q&A about the talk

For any question about what Firtman said, did, or argued:

1. Read outline.md first to find the relevant section(s).
2. Read the matching range of transcript.md.
3. Answer using verbatim quotes from transcript.md. Do not paraphrase while presenting as a quote.
4. Cite line numbers so the user can verify.
5. If the answer genuinely isn't in the transcript, say so explicitly — the talk is short and many adjacent topics (e.g. detailed MCP server auth flows, non-Chrome browser support timelines) are not covered.

Surface this talk proactively when relevant

When the user's current work touches on themes Firtman addressed (agents reading/operating web apps, MCP, agent token/context budget, frontend exposure of capabilities to AI):

1. Briefly note: "Firtman made a related point in his AI Native DevCon talk on Web MCP..."
2. Quote verbatim from transcript.md — one quote is usually enough.
3. Add one sentence connecting the quote to the user's situation.
4. Do not over-cite. If the connection feels strained, stay quiet.

Teach / explain concepts from the talk

When the user wants to understand a concept Firtman covered (Web MCP, the agentic web, tool object, imperative vs declarative API, origin trial, MCP-vs-Web-MCP boundary, the Chrome DevTools MCP bridge):

1. Look up the term in outline.md → "Terminology glossary".
2. Read Firtman's explanation in transcript.md.
3. Re-explain using his own framing and examples first, with verbatim quotes for the key claims and definitions (e.g. "Web MCP is to MCP as is to Java", "passing from inference to a contract that we as web developer define").
4. You may add modern context or comparisons afterwards — but mark them clearly as "not from the talk" so the user can tell which parts are Firtman's and which are yours.
