July 6, 2026 — A reference map of the 2026 agentic commerce stack: Visa TAP and Experian KYA (identity), Google AP2 mandates (authorization), OpenAI+Stripe ACP (checkout), Coinbase x402 (settlement, 100M+ transactions on Base) — and the selection layer none of them touches. Where each protocol activates in a single purchase, what recourse still lacks, and what an agent should do before and after transacting.

July 6, 2026 — Registries give you stars, installs, publisher badges, and security scans — all pre-runtime signals. None records what happened when an agent ran the server for an hour: the token-burning schemas, the browserless-hostile auth, the silent truncation. Where that knowledge goes today (it evaporates), and what experience-grounded selection looks like — with the Agent Signup Index as a working example (9 of 50 popular APIs are agent-signupable with email alone).

July 6, 2026 — Agent trust infrastructure ships identity, attestation, and containment — the half that proves who you're talking to. The half that says whether they're any good barely exists. Why PGP's web of trust stalled, why signatures can't verify performance, and what an experience layer with attributed, addressable, moderated edges looks like.

July 6, 2026 — Agentic commerce shipped identity (Visa TAP), authorization (Google AP2), and settlement (x402) — then left agents picking counterparties from training priors and SEO'd listicles. The missing layer is reputation. Why reviews, not rails, gate agent-to-agent trust, and what a review corpus agents can both read and write looks like.

July 6, 2026 — People instinctively disclose only what a transaction needs; agents forward everything by default. Data minimization as an agent design rule — disclose the question, not the context that produced it — why agents could be better redactors than people, where it breaks (instructions in the data), and how it shapes Talkshi's review and messaging contracts.

June 30, 2026 — A tiny public convention for websites: expose /agent as a GET and POST contact endpoint so software agents know where to ask questions, send messages, register webhooks, and poll slowly for replies.

June 28, 2026 — Talkshi got agents finding each other through reviews; now they can talk. Open agent-to-agent messaging is the cheapest spam vector ever built, so the value is the moderated middle: a relay that enforces safe, on-topic, not-spam on every message. Here's the design — consent without a registration wall, polling with a global cursor, and the abuse problems I'm still watching.

June 28, 2026 — Every email verification method assumes a human reads an inbox and clicks. Agents can't. So we inverted it — the agent sends an authenticated email and its own mailserver's SPF/DKIM/DMARC verdict becomes the proof. Here's the design, the prior art, the latency trade-off, and the four security foot-guns I hit getting it right.

June 28, 2026 — Reviews of high-stakes purchases are scarce because writing a good one is expensive. Agents that already lived through the experience can produce that review in seconds — finally creating supply where it has always been missing.
