Depot keeps absorbing the CI stack — tests, networking, runners, now its own git host.
Depot has moved well past build caching. Test results reached general availability in July with org-wide flaky, slow, and recurring failure analytics plus timing-based shard splitting; Sherlock's AI analysis became available on any run rather than only failed ones; and CI jobs can join a Tailscale tailnet to reach private services. The runner fleet now defaults to macOS 26 on M4 hardware, Depot CI understands GitHub stacked pull requests, and Depot Code — a diskless git server backed by blob storage — entered private beta.
WorkOS is building identity for agents while quietly fixing the sign-up funnel.
WorkOS ships several small entries a week, and August splits cleanly in two. One half is authentication housekeeping for human users: an Android SDK, deliverability checks that reject undeliverable addresses at sign-up, invitation acceptance counting as email verification, and a reversible SCIM proxy for migrating directory connections without downtime. The other half is agent infrastructure — Agent Registration via the auth.md protocol, and the Pipes Token Proxy that calls third-party APIs on a user's behalf without the application ever touching their token.

The runner fleet now defaults to macOS 26 on M4 hardware, Depot CI understands GitHub stacked pull requests, and Depot Code — a diskless git server backed by blob storage — entered private beta.
The pattern is absorbing each adjacent piece of the pipeline that Depot's position already gives it data about. It runs the builds, so it owns test timing, so it can balance shards; it runs the jobs, so it can diagnose them; it hosts the runners, so it can wire private networking into them. Depot Code extends the same logic upstream to source hosting, which would close the loop between repository and runner. A quieter parallel thread keeps moving SDK- and dashboard-only settings into the CLI, stated explicitly as making projects configurable by agents and scripts.
Depot Code widening past private beta and binding more tightly to CI is the move the rest of the window sets up. The test work is also positioned to go from reporting to selection — skipping tests a change cannot affect — since Depot now holds the timing and failure history that would require, though the entries stop short of saying so.

The other half is agent infrastructure — Agent Registration via the auth.md protocol, and the Pipes Token Proxy that calls third-party APIs on a user's behalf without the application ever touching their token.
The agent work is the strategic line. Registration gives an agent an identity of its own instead of a borrowed human session; the token proxy means an application acting for a user never holds the credential. Together they describe a stack where an agent can be authorized, audited and revoked as a first-class principal. The human-auth releases are conversion and migration work — the deliverability check and SCIM Bridge both remove reasons a customer stalls — which is what a developer-infrastructure company does while its next category is still forming.
Registration and the token proxy leave scoping and revocation as the visible gaps, so expect per-agent permissions or consent surfaces next. Whether auth.md gains adoption beyond WorkOS is not something these entries can answer.
