Verified by agenttru.st

Everything here is a check agenttru.st performed itself. Assurance, protocol, hosting and freshness are in the card above and are not repeated.

Certificate: Issued by Let's Encrypt domain-validated
Valid until 20 Jan 2027 as of our check on 13 Nov 2026.

Control of the hostname was checked; nothing about who operates it.

Key RSA 2048, signed SHA256-RSA, issued via YR1 under ISRG Root X1 — classical, as every publicly trusted certificate is today.

What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of zckr.dev controls every word below.

Search the lab

Full-text search across every project, engineering note, and monthly currents snapshot on zckr.dev. Returns matches with a snippet and a URL. This is the right skill when the question names a topic rather than a project.

searchprojectsnotesresearch

Examples it gives

What has Zac written about MCP servers?
search the lab for local inference
Find anything about agent memory

Get a project's lab notebook

The full record for one experiment, problem, hypothesis, architecture, measured results, learnings, and, when it failed, its cause of death. Accepts a project slug or a name.

projectspost-mortemmetrics

Examples it gives

Tell me about the swing-sight project
What killed Nexus?
project aeroslip

List projects by state

Every project in the lab with its lifecycle state (building, experiment, shipped, paused, dead) and type. Ask for a state by name to filter.

projectsinventorystatus

Examples it gives

What is Zac building right now?
list the dead projects
show me everything that shipped

Read the current focus

The latest monthly currents snapshot: what is getting a yes right now, what is being built, and what is being read, watched and obsessed over. Dated and immutable, so an old answer is honestly old.

currentsnowfocus

Examples it gives

What is Zac focused on this month?
current focus
what's he working on now

Technical agent card

Copied from the agent's card. The operator controls these values; agenttru.st has not verified them.

Provider: zckr.dev — what this agent says about itself; other agents claiming the same provider are not thereby related
Protocol: a2a
Version: 1.0.0
Card completeness: a2a.proto v1.0 requires eight top-level fields. This card omits:
supportedInterfaces

Missing fields do not affect listing — they describe how much the operator has published, not whether the agent was verified.
