An agent's answer is readable in the chat and the property panel

[endrix]

A wfpy agent finishes a turn by writing its ports, and the runtime reports that as one JSON object whose port values are themselves JSON. The text reaching the UI is escaped twice, so a unified diff arrives as a single line of \n and \". In the chat it rendered as one unreadable paragraph. In the property panel it was worse: the value was truncated at 500 characters, and what did show went through the Markdown heuristic, whose list rule matches any line beginning with a dash and a space, which is every removed line of a patch. A diff therefore rendered as a bullet list with its minus signs eaten, which silently changes what the patch appears to say.

What changed

agent-outputs.ts is a new module with one job: turn an outputs object into Markdown the panel already parses and sanitizes. A heading per port, one line per scalar field, a fenced block for anything long, tagged diff when it is one. Scalars come before blocks so the options and the reason read before the patch. Prose keeps its punctuation while an option string gets backticks. A value carrying its own fence gets a longer one. Anything that is not an outputs object returns null and goes through untouched, so ordinary replies are unaffected.

The property panel shares that module's three predicates rather than copying them, so the two views cannot drift on what counts as a diff. Its string branch now unwraps an embedded JSON value and recurses into the tree, and sends a diff or any multi-line string to a scrolling monospace block styled from the editor's own tokens.

Before and after

A planner's round, as the chat showed it:

{"outputs":{"Next":"{\"front_options\":\"ftd=auto\",\"handshake_options\":\"target=asap7 ...

and as it shows it now:

### Next

- **front_options** `ftd=auto`
- **handshake_options** `target=asap7 decision-slots=4 ...`
- **stop** `false`

**model_patch**

Testing

Nine tests on the new module, including a real planner answer from a run, a bullet list that must not be taken for a diff, a broken JSON string that must be returned untouched, and a value containing its own fence. The package's 198 tests pass and all five packages type-check.
