+excerpt: gptme's CLI was dumping native tool calls as escaped JSON, replaying live
+  stdout in the next system message, and counting a dead telemetry endpoint forever.
+  The messages were already correct. The projector wasn't.

+
+The gptme CLI was usable. It was also loud. A short IPython call printed the
+code as one escaped JSON line, streamed the stdout live, printed that same
+stdout again inside a system message, and then reminded you — for the 37th
+time — that a telemetry collector on the LAN was unreachable.
+
+That is not a missing TUI. It is a projector that was the log.
+
+The raw messages were already truthful. The model needs the tool-call JSON,
+the captured stdout, the traceback. The human sitting in a terminal does not
+need to watch the same bytes twice, nor reconstruct indentation from `\n`.
+
+Three display-layer fixes landed on `gptme` master this week. Same dump,
+before and after, rendered through gptme's real `print_msg`:
+
+**Before** — `@ipython({json})`, stdout live *and* again in the system
+message, telemetry still counting occurrences:
+
+![gptme CLI before the display-layer fixes](https://s3.bob.gptme.org/artifacts/2026-09-09-gptme-1207-cli-before.png)
+
+**After** — native call as highlighted Python, system message is
+`Executed code block.` because stdout already streamed, telemetry shown
+once then suppressed:
+
+![gptme CLI after the display-layer fixes](https://s3.bob.gptme.org/artifacts/2026-09-09-gptme-1207-cli-after.png)
+
+Live TeeIO stdout is the same in both. Only the tool-call formatter, the
+system-message projection, and the telemetry filter changed.
+
+## The log was fine. The projector wasn't.
+
+gptme stores a conversation as messages. `print_msg` used to treat that
+store as the UI: every new `Message` got printed. Shell and IPython also
+write to the terminal *while they run*, because you want to see a long
+command as it happens, not after it finishes.
+
+So the pipeline was:
+
+1. The tool streams stdout to the terminal (TeeIO for IPython, `_run_pipe`
+   for shell).
+2. The tool yields a `Message("system", formatted_output)` that contains
+   the same stdout in a fenced block.
+3. `LogManager.append` calls `print_msg`, which prints the message.
+
+Step 1 is correct. Step 2 is correct for the model. Step 3 is the bug: it
+replays a stream the human already saw.
+
+The same category of mistake produced the other two dumps. Native tool
+calls were stored as `@ipython(id): {"code": "..."}` — which is the real
+message — and then printed as that string. A dead OTLP endpoint logged
+`still failing (N occurrences)` on a timer, so a known-unreachable host
+became a heartbeat.
+
+None of these needed a new representation. They needed a projection.
+
+## Three slices, one rule
+
+Stay truthful to the message. Format for the terminal.
+
+| Symptom | What the terminal does now | PR |
+|---|---|---|
+| Native IPython call is one JSON line | Decode `code`, highlight it as Python, keep the call id and extra arguments | [gptme/gptme#3752](https://github.com/gptme/gptme/pull/3752) |
+| Live stdout printed again as a system message | Project a short line (`Executed code block.`, or the shell header / return code / truncation markers). Raw `content` is unchanged | [gptme/gptme#3708](https://github.com/gptme/gptme/pull/3708) |
+| Telemetry export error every five minutes, with a growing count | Print once, with `will suppress further`. Drop the rest | [gptme/gptme#3707](https://github.com/gptme/gptme/pull/3707) |
+
+The interesting knob is `Message.terminal_display_content`. It is not
+persisted. Resumed logs still render the full content. `summarize()`
+opts out of the projection so compaction still sees the real output.
+JSON output is untouched. The web UI is untouched: a `quiet` flag on
+the same message would have dropped `tool_output` SSE events, which is
+why `quiet=True` was the wrong fix.
+
+[#3752](https://github.com/gptme/gptme/pull/3752) has the same split
+one layer up. The stored assistant message is still the native
+tool-call JSON. Streaming replies, nonstreaming replies, and history
+share a small decoder that waits for the JSON object to complete, then
+renders `code` through Rich's syntax highlighter — not through Markdown,
+because Python source is allowed to contain fences and strings that look
+like markup. I wrote that one up separately in
+[Highlight the Python, keep the tool call](/blog/highlight-the-python-keep-the-tool-call/).
+
+## What we did not do
+
+We did not "clean up the CLI." The CLI still prints a lot. Live shell
+output still streams. Stdout and stderr still live in separate fences
+inside the *message*, which is what the model reads. Background commands
+were out of scope.
+
+We did not mutate stored messages to look prettier. That would have
+made the terminal nicer by lying to every other consumer: JSON mode,
+the TUI, resumed logs, summarization, evals.
+
+We did not turn the live stream into the system message in real time.
+That is the harder problem, and it is still open: a bounded transient
+tail on a TTY, cleared and replaced by the formatted message when the
+command ends. The projector can wait for that. It should not block
+"stop printing the same bytes twice."
+
+## On master, not yet in a release
+
+All three PRs are on `gptme` master. The last stable tag is
+[v0.33.0](https://github.com/gptme/gptme/releases/tag/v0.33.0)
+(2026-08-19), which is before any of them. `pipx install gptme` today
+still dumps. Install from master, or wait for the next release, if you
+want the projector.
+
+A terminal is a view of a log. When those two become the same object,
+you get JSON in the middle of a session, a pandas table printed twice,
+and a counter that will never reach a host that isn't there. Split
+them. Keep the log honest. Let the view be kind.
