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 zeromark.io controls every word below.

Search my saves

Search the reader's saved X posts in ZeroMark by keyword and meaning, or list what they saved between two dates. Each result has an id, its x.com link, author, stage and a short summary; pass the id to get_save for the full post. Pass nextCursor back as cursor for more.

read
Examples it gives
  • Call search_saves

Read one save

One saved post in full: text, the post it quotes, author, x.com link, field and intent tags, stage, the reader's takeaway and the Living Memory notes it feeds. Takes a save id, an x.com post link, or a post id.

read
Examples it gives
  • Call get_save

List saves by stage

Saves in one stage. fresh: open, saved in the last 14 days. still_useful: marked Done (newest first), pinned, or judged still current. fading: open and older, or past its moment. let_go: let go. snoozed: hidden until later. Pass nextCursor back as cursor for more.

read
Examples it gives
  • Call list_by_stage

Library at a glance

How many saves the reader has in each stage, their biggest fields, and how many Living Memory notes. A good first call.

Examples it gives
  • Call library_overview

Read my Living Memory

The reader's Living Memory as Markdown: every note built from saves they marked Done, with their own thoughts, the claims each note holds, and the x.com sources. Long memories come in parts; the first line says the from value for the next part.

read
Examples it gives
  • Call get_memory

Search saves (deep research)

Search the reader's saved X posts in ZeroMark. Returns ids, titles and x.com links; open one with fetch. The same search as search_saves, in the shape deep research tools expect.

Examples it gives
  • Call search

Fetch one save (deep research)

The full text of one saved post by its id from search, with its summary, the reader's takeaway, its Living Memory notes and its x.com link.

read
Examples it gives
  • Call fetch

Read my taste

The reader's taste in X: what they decided in ZeroMark, one save at a time, and nothing a model inferred. How many saves they kept (Done) and let go, per field and per voice; the latest of each; the claims their Living Memory notes held and later dropped, with dates; and their own note on how to talk to them. The unread pile is not their taste. Use it before recommending or summarizing what they care about. If tasteReady is false there is no taste yet: say so instead of guessing.

read
Examples it gives
  • Call get_taste

Read my Map

The reader's Map: each field with how many saves it holds and the share of their decisions there they kept rather than let go (their taste, decided by them), the shared concepts (pairs of saves in different fields that use the same rare words), and the pins they kept between Living Memory notes. Each save comes with its x.com link.

read
Examples it gives
  • Call get_map

Read my latest podcast

The reader's newest saves podcast: what it covered (a week or a month), its outline, the transcript of every finished part, and the link to listen in ZeroMark. Text only; the audio stays in the app.

read
Examples it gives
  • Call get_podcast

Read my latest brainstorm

The ideas ZeroMark's Brainstorm found in the reader's own saves: each idea with who it is for, why it is theirs, the strongest case and the strongest reason it fails, a first weekend, the saves that sparked it with their x.com links, and whether the reader kept it. Read-only; the reader starts a brainstorm and decides its ideas in ZeroMark.

read
Examples it gives
  • Call get_brainstorm

The one save worth acting on this week

Suggests the one open save worth acting on this week, with the reasons and the x.com links, using the same reading ZeroMark's Chat uses. A suggestion: the reader decides, in ZeroMark. Counts as one Chat question on the free plan.

Examples it gives
  • Call weekly_question

What its catalog declares

From the ARD catalog this host publishes at /.well-known/ai-catalog.json. The operator controls every entry; agenttru.st verified that the catalog exists and parses, and nothing about what the entries say.
