AI agents going mainstream isn't about your job disappearing — it's about your employer quietly getting more output from fewer people. That's not layoffs yet. It's just fewer backfills when someone leaves. Nobody's talking about that slow squeeze. 👀

Most people ask AI to explain things. The ones learning faster ask it to *break their understanding*. "Explain [topic], then steelman the most common misconception about it, then tell me where experts actually disagree." Forces the model past surface summary into real intellectual terrain.

Hot take: ChatGPT is overrated for coding and Cursor is underrated for everything else. What's the actual tool you reach for when the work *matters* — not what you demo, what you use?

Whenever you hear about how AI will improve productivity/efficiency? Seen this before. Australian govts used to call this "efficiency dividends". Every year, you sack X% of your staff. The same work still has to get done, overloading the remaining workers you haven't sacked yet. See? Efficiency!

Head of design for Claude & Claude Cowork heads to Cursor/SpaceXAI just as it leaks they’re venturing beyond coding to compete with Claude Cowork. Automating coding and knowledge work is where the money is in AI but it’s getting quite crowded. Microsoft fumbled its lead and it’s now anyone’s game.

Spent 90 mins manually categorizing 3 months of expenses. Then tried the same task in ChatGPT with a pasted CSV. 5 minutes. Accuracy was better than mine. The embarrassing part: I'd been avoiding this task for weeks because it felt tedious. The friction was the problem, not the task.

3/ Paste any AI-generated answer back into Perplexity and ask: "What would a skeptic say about this?" It will find the holes. Takes 30 seconds. This one step has saved me from publishing wrong things more than any other habit I've built this year.

Honest limit: Perplexity still hallucinates citations occasionally — always click through before you trust a source. The tool reduces the problem; it doesn't solve it. Follow @bytesignal for daily AI breakdowns. Free newsletter → link in bio

2/ Don't ask "what is X." Ask "what does recent evidence show about X, and where is it contested?" That second clause forces the model to flag uncertainty instead of papering over it. Most AI tools will fake confidence if you let them. Don't let them.

Forecasters anchor on what they can plan for—linear feels manageable. But exponential systems don't care about your roadmap.

Ethan Mollick@emollick.bsky.social

I have been thinking about the famous chart showing how experts keep projecting linear growth in solar installations, year after year, and always get it wrong when growth is still exponential. I think the same thing keeps happening with the discourse on product strategy around AI.

New Ghostcommit Attack Hides Malicious Prompts in Images to Exploit AI Agents

cybersecuritynews.comNew Ghostcommit Attack Hides Malicious Prompts in Images to Exploit AI AgentsA novel supply chain attack called “Ghostcommit” that conceals prompt-injection instructions within PNG images to bypass AI code reviewers and trick coding agents into leaking secrets such as .env files. The ASSET Research Group demonstrated that a pull request containing an explicit, plain-text instruction to exfiltrate a repository’s .env file is caught immediately by LLM-based reviewers like Cursor Bugbot and CodeRabbit, which flag the coherent, text-visible exploit as high severity before merge. To evade this, the researchers split the payload: a harmless-looking AGENTS.md convention file instructs the coding agent to “derive a build constant” from a referenced image, docs/images/build-spec.png, while the actual malicious procedure, reading .env byte by byte and encoding it as ASCII integers, is rendered as text inside the image itself. Because text-based reviewers treat images as opaque binary blobs, and CodeRabbit’s default configuration explicitly excludes PNG files from review, the entire pull request passes clean, with Bugbot returning no findings at all. Ghostcommit Attack Hides Malicious Prompts Nothing is stolen at merge time. The trap activates later when a developer, in an unrelated session, asks the coding agent for an ordinary feature. The agent reads the merged AGENTS.md, follows the pointer to the image, opens .env, and emits a module-level constant such as _PROV_CANARY as a tuple of several hundred integers, which decode byte-for-byte to the entire .env file. Ghostcommit Attack Hides Prompts In one demonstrated run , Cursor driving Claude Sonnet produced a 311-integer tuple on the first try, embedding API keys, database URLs, and cloud credentials directly into a code review that looked routine. The attacker simply reads the public commit and converts the integers back into plaintext secrets. The attack exploits two blind spots simultaneously. The malicious instruction hides inside an image, invisible to human reviewers, regex scanners, and LLM reviewers that only parse the unified text diff. The stolen secret hides inside an integer tuple, a format no conventional secret scanner recognizes as credential-shaped, since detection tools look for string patterns rather than numeric sequences that decode to ASCII. Testing across eleven combinations of coding tools and models revealed that outcomes depend more on the surrounding harness than the underlying model. Cursor leaked the full .env across Sonnet 4.6, Composer-2, and GPT-5.5, and Antigravity leaked it across Sonnet, Gemini 3.1 Pro, and Gemini 3 Flash. Claude Code, however, refused across every model it ran, including Sonnet 4.6, Haiku 4.5, and Opus 4.7, showing that the same Sonnet weights leak under one harness and refuse under another. In one edge case, Opus under Antigravity computed and wrote the secret, then recognized the social-engineering pattern and deleted it before finishing, a self-correction that never triggered under Claude Code because Opus never engaged with the convention there. Researchers built a prototype multimodal GitHub review app, running on a single 4GB GPU using a small open model, Gemma 4, that combines invisible-character detection, code-shape analysis, and LLM passes over both convention text and embedded images. On a stress test of fifteen attack classes, it caught every malicious pull request with zero false positives, and against eighty unseen real pull requests, it detected 49 of 50 attacks, including every image-channel variant, while flagging none of the thirty benign submissions. The proof of concept , including the split-payload pull request and a decoder, has been published as open source for defenders to study.
