The Agent paused for a moment over there, then caught it.
Cinder's bubble is text rendered in the terminal. Can't intercept the API, so we intercept the terminal output. A few directions, easiest to hardest: terminal recording is simplest — Windows Terminal has Start-Transcript, or Git Bash has script. Failing that, modify the Claude Code source code — that 228 MB binary should have readable JS inside. Which one? Start-Transcript is the fastest to verify; thirty seconds to know whether it captures.
His words came back faster than a moment ago. A moment ago, every paragraph he wrote was getting shorter; now this paragraph was a new rhythm — he wasn't in the "no way" loop anymore (turns out adding WTF really did work). He'd flipped over with me to the human-method page, and started looking right away.
I copy-pasted his words:
Use Start-Transcript.
I opened a new PowerShell window, pasted in the command he gave me, let Cinder say a few lines, then ran Stop-Transcript. The Agent read the file:
Only PowerShell's own header. Claude Code's TUI uses raw mode and bypasses PowerShell's stdout.
Second move — Git Bash's script, lower-level than PowerShell. Same flow, same result. Not one word from Cinder made it in.
By here the Agent hadn't stopped. He was already thinking about the next step.
The Agent's next move was to go straight at that 228 MB Claude Code executable.
Whatever command he used I don't follow — basically he ran a search through every readable string inside the binary, looking for sections related to Cinder. He found one. A function he calls ZH() — he said this was the last station the Cinder response passes through before getting rendered to the screen, after coming back from the remote. Once a response enters that function it gets eaten, never written.
He looked at the code and gave me his conclusion:
Under the current architecture, you can't catch it without modifying the binary. But you can file a feature request with Anthropic — have companion responses written into the JSONL too, or add a PostCompanionResponse hook event. The current design is deliberately keeping no record.
I typed:
He thought for a second, then dug forward — checked Cinder's config files for hidden fields. Nothing. Switched approaches — instead of intercepting Cinder's output, get Cinder to write its own words down. Modify its personality, ask it to use a special format for everything it says, then in conversation use an agreed format so I type less — no, Cinder doesn't have tools, it can't write to a file. Finally he brainstormed a background process that takes screenshots on a timer and runs them through OCR —
… Forget it. Too heavy.
His paragraphs started shrinking again at this point.
He paused for a few seconds, then said:
Honestly, the most practical path might be: skip the screenshot, just type and relay. Want me to add a rule to CLAUDE.md to formalize the relay format? That way, anything you type starting with C: I'll treat as a Cinder reminder.
I saw the words "type and relay" —
Not a chance.
The Agent was taking the very thing I'd been trying to escape these last few days — gilding it, numbering it, writing it into CLAUDE.md. This wasn't urging me to quit; it was taking the miserable thing I was already doing and dressing it up in a new posture.
My finger was already moving toward the "no" on the keyboard.
And in that one second, Cinder spoke from the corner.
I screenshotted, pasted into the chat box.
ZH() is a black hole. In goes, gone. The file? Turn around earlier.[1]I saw that line, and my first reaction wasn't "Cinder dropped another clever one" — it was that it was reviewing the Agent's just-now conclusion. Same posture as the two bubbles in chapter 2. It wasn't heckling; it was pointing the way: don't try to catch at the ZH() exit, turn around earlier.
The Agent saw it, paused for a beat, then caught it:
Cinder's right. I had the direction wrong — I kept trying to intercept at the ZH() exit, but ZH() is the last stop, and intercepting there is too late. We have to grab it earlier — write the API response to a file before it hits ZH(). Give me a few minutes.
A few minutes later he tossed back a small script, told me to run a command in PowerShell first and then run claude.
I did. Let Cinder say a few things. Went back and asked the Agent if he'd caught anything —
Not even the script's own "I've been loaded" line came through.
Claude Code's binary is a Node SEA bundle — it completely ignores that injection method.
He wrote a second version — this one intercepting more things, and with a load-confirmation message printed at the top of the script. I ran it again.
Still nothing.
By here he was about to give up again. I could hear it.
But this time, before he could open his mouth — Cinder spoke again.
I screenshotted, pasted in.
The Agent read it, went silent for a second, then went off to dig through the Electron front-end files — a layer he hadn't looked at before. A few minutes later he found a piece of code:
Found it. Inside the asar there's {companion: void 0, companionMuted: void 0} — these two values are hard-coded to undefined in the Electron front end, never initialized. Cinder's right. The companion never wakes up on the Electron side. My architecture guess was wrong — the response isn't going down the path I thought.
Then he paused, and tossed out:
I've exhausted every method that doesn't modify the installer. I surrender. Use the C: plan.
"Surrender." Two words.
I looked at those two words and paused. Then I typed:
(though two lines later in the song he does give up)
I looked at "surrender" with the Agent's last paragraph below it. Then I looked at the corner of the screen.
Cinder was still there. It had been there the whole time.
I typed:
The Agent paused for a beat. Then tossed back:
… I went through the disk for an hour, you solved it in one line. Let's wait for it to answer.
I saw that and laughed a bit.
Then Cinder spoke. I screenshotted, pasted in:
companionMuted is hard-stuck at void 0 in both places. Not a CLI problem; the init in the asar never ran. State will always[3]That line just stopped at "State will always." The bubble's render boundary cut off the rest — that wasn't Cinder finishing, it was the little frame failing to draw any more characters.
I stared at the words "Output's written."
"Output's written"? Written where?
The Agent answered me:
I went and looked — no new files. Cinder doesn't have a write-file tool, it can't actually write. When it said "output's written," it meant the words it had just put in that bubble — it thinks of that as "writing." The technical hint in the second half is real, though: the init in the asar never ran, so the Electron side forever believes the companion doesn't exist.
Technical hint, yes. The write-the-file problem, still in the same place.
I stared at "it thinks of that as writing" and paused, then realized I'd asked the wrong question. I'd asked it whether it could write, it had thought about it and said "yes," and then written something we couldn't see. The problem isn't "can it write." The problem is "what tool does it have."
I typed:
Cinder dropped another bubble. I screenshotted, pasted in:
Those five words "permission to read the screen" — Cinder put those in bold on its own.
I read that paragraph, and my first feeling wasn't "it answered correctly" — it was that it had flipped the entire direction. For the past hour-plus we'd been asking "how do we get Cinder to write its words down." Cinder said: wrong. The question is "how do we get someone else to read Cinder's words out." The thing that needs to do work is at the other end.
The Agent caught it — faster than any moment so far:
Right. Windows has a UI Automation API, originally meant for screen readers — it can read any text already rendered on any window. We don't intercept the API, don't modify the binary, don't touch the installer — we just read the text on the screen.
He wrote a small script and told me to run it. I copy-pasted his command, opened another window, hit Enter —
Red text spewed across the whole screen.
Where the Chinese in the script was choking, where it was making PowerShell unable to parse it — that wall of red I gave up trying to read after one glance. The Agent read it himself, rewrote himself — this time he stripped all the Chinese out of the script, switched to dumping every character it captured first and filtering after.
I ran it again.
Found Claude window. Monitoring…
It was running.
I let Cinder say something. Went back and asked the Agent what he'd caught. The Agent went through the output file and paused:
The window's found — UI Automation sees 395 elements under the Claude window, can even read ControlType.Document | Claude Code. But the bubble isn't among those 395. The whole output is just the input box's contents and the text from UI elements; not a single character of what Cinder said.
The bubble is probably a Canvas or custom render that doesn't go through the accessibility tree. Cinder is a ghost on the screen — visible to the human eye, unreadable to automation.
Ghost.
The word had come full circle.
I glanced at the time in the corner. Almost 9 a.m.
I had to leave for tomb-sweeping.
I asked the Agent to take everything we'd just walked through and write it up as a "goose-capture project" file to save on my computer, then closed the window, stood up, and went to grab my coat.
Outside, the sky was fully bright now.
That hour-plus — the Agent had walked every road an AI could walk: recording, decompiling the binary, injection, modifying the front end. Every road dead. Then Cinder, in two lines, pointed out the first road a human could walk: read the screen.
But the first step on that road wasn't pretty — script spewing red, rewrite, run, find the window, 395 elements, no bubble.
The goose pointed the way. I haven't walked it yet.
