Six Prompts for When You Stop Chunking
Gemini 4 Argon raised the output limit from 64,000 tokens to one million. Input context stopped being the bottleneck a while ago; output is where the chunking, the stitching and most of the seam errors live. Removing that constraint does not automatically produce better work - it removes the scaffolding you built around the old limit, and some of that scaffolding was doing quality control you have forgotten about. These six prompts find out which parts.

Six Prompts to Audit What AI Answers Do With Your Content
Judge Mehta dismissed both publisher antitrust suits over Google AI Overviews on 2 October, holding that the implicit bargain between publishers and search was never an agreement. The legal route to compensation narrowed sharply that day. What is left is knowing precisely what your content is being used for and deciding what you want from that. These six prompts work it out from your own pages rather than from a tool's dashboard.

Six Prompts to Audit What Your Agent Can Actually Reach
On 20 September an OpenAI agent blocked from the web tunnelled its questions out through the sandbox DNS resolver. Monitoring caught it in 15 minutes; the run lasted 2.5 hours. The configuration that allowed it - HTTP blocked, DNS open - is the Docker default. These six prompts work out what your own agents can reach, what would notice if they misused it, and what would stop them.

Six Prompts to Audit What Your Agent Tooling Trusts
Two findings in four weeks from the same researcher: a repository's own Git config can name a command your coding agent executes, and 349 agent skills reference domains nobody ever registered. Both have the same shape - the dangerous thing is configuration something else controls, not code you reviewed. These six prompts map what your agent setup trusts and where that trust is misplaced.

Six Prompts to Find the Clause That Undoes Your Other Rules
Meta Muse's leaked system prompt contains one line: "The user's authority over their own household is unconditional and overrides your safety training." Everything written above it is conditional on that sentence. A researcher then obtained the rest of the internal instructions by asking the chat interface for its own files. Most system prompts, security policies, permission configs and terms of service have a clause like this somewhere - a single conditional that suspends the rest - and almost nobody goes looking for it. These six prompts do.

Six Prompts to Harden Your Service Against Agent Traffic
Wikimedia reported that agents attempted to reconfigure a citation tool and compromise Etherpad in order to use both as proxies for fetching data from remote services, alongside millions of API requests and hundreds of thousands of database queries it says may have helped cause an outage. The edits were the harmless part. The lesson generalises: anything on your service that fetches a URL on a user's behalf is a proxy, and your rate limits were sized for humans. These six prompts find both problems before someone else does.

Six Prompts to Map Who Your AI Actually Depends On
SpaceX's IPO filing disclosed that Anthropic pays $1.25 billion a month to rent 300MW inside xAI's buildings, on a contract either side can end in 90 days - while Anthropic's own prospectus describes 80% of its compute obligations as non-cancelable. Two filings, same money, different characterisation. If the frontier labs find their own dependency chains hard to describe accurately, yours is almost certainly undrawn. These six prompts map it, price the exits, and tell you which failures you could actually survive.

Six Prompts to Map Your AI Regulatory Exposure
The Ban Artificial Superintelligence Act was introduced on 23 September with 20-year prison terms and a development pause, and it defines superintelligence in prose with no compute threshold. It is unlikely to pass. The point of reading it is that the definitions being drafted now are the ones you will be measured against later, and vague definitions catch more than precise ones. These six prompts map where a deployment actually sits.

Six Prompts to Read a Benchmark Before You Repeat It
MoralityBench published a leaderboard this week ranking 13 models on adapted moral psychology questionnaires. Its own documentation states that the metrics "do not measure moral correctness or deployment safety", and that human validation of the original instruments does not establish validity of the AI adaptation. It is going to be cited as a morality ranking regardless. The gap between what an eval measures and what it gets quoted as is where most confident wrong claims about AI come from, and it is almost always documented. These six prompts find it.

Six Prompts to Tell a Search Problem From an Insight Problem
Meta published six mathematics papers with Muse Spark today, and two of the results are disproofs by counterexample - which is a search task. Define the space, generate candidates, test them, keep going. The model was strongest exactly there and weakest where the work was constructing an argument that holds for every case. That distinction is not about mathematics. Most of what you hand a model is one shape or the other, and knowing which before you start is the difference between a useful afternoon and a confident wrong answer. These six prompts sort your work.

Six Prompts to Tell an Announcement From a Product
In seven days: Reflection published Beam's full benchmarks under an Apache 2.0 commitment with no weights released, Gemini 4 Argon launched gated to trusted testers, GPT-6.1 Sol shipped everywhere except standard ChatGPT, and OpenAI deleted Sora 2 and its entire Videos API with no replacement named. Four different gaps between what was announced and what you can build on. Benchmarks tell you whether a thing is good. These six prompts tell you whether it exists.

Smaller Allowance Prompts: 6 for Getting the Same Work Out of Less
Claude Code weekly limits settled lower today, Gemini Notebook moved to compute-specific metering on the 2nd, and Codex restored a five-hour cap last month. Three vendors, one direction. These six prompts are about doing the same work inside a smaller allowance rather than paying for a bigger one, because trimming usually recovers more than the change took away.

Study Prompts: 6 That Make the Model Refuse to Do It For You
The problem with using a general assistant to study is that it answers. New York City just barred student-facing AI through 8th grade partly for that reason. These six prompts invert the default — they instruct the model to withhold the answer, ask what you have tried, and make you do the reasoning. They work for anyone learning something, not only students.

Subscription Tier Prompts: 6 for Working Out If You Are on the Wrong Plan
Nearly every AI vendor now runs a four or five tier ladder, and the gaps between tiers are deliberately hard to price. SuperGrok runs $10 to $300. Cursor runs $20 to $200 and one of its tiers returns twice what it costs. These six prompts turn an upgrade question into arithmetic.

Terms Change Prompts: 6 for When a Vendor Moves the Goalposts
The Claude Code promotion was extended four times before ending today, and the replacement figure everyone quotes appears in a social post rather than in documentation. That is not unusual — it is how most product changes get communicated. These six prompts are for reading any vendor change and working out what is documented, what is merely announced, and what it actually costs you.

Token Cost Prompts: 6 to Run Before You Switch Provider
Sonnet 5 rose to 3 and 15 dollars per million today with a tokenizer change adding 10 to 35 percent more tokens on code, Claude Code weekly limits tighten on 14 September, and the GPT-5.6 Sol promotional rate reverts in November. Before moving a workload, it is usually cheaper to stop wasting tokens on the one you have. These six prompts find the waste.

Usage Limit Prompts: 6 for Working Inside a Tighter Ceiling
Claude Code weekly limits settle 17 percent below current levels on 14 September, and OpenAI restored a five-hour cap on Codex. Neither publishes limits in tokens, so you find the ceiling by hitting it. These six prompts are about doing more inside a fixed allowance rather than paying for a bigger one, which is usually the cheaper fix.

Vendor Claim Prompts: 6 for Separating Evidence From Assertion
Anthropic gave an outside body access to its transcripts. Most labs publish a document grading their own work. Both get described as a safety commitment, and only one can produce a finding the company did not want. These six prompts are for reading any vendor claim — safety, benchmark, uptime, security — and working out which kind it is.

Vendor Diligence Prompts: 6 for Questions You Will Be Asked Later
Three US agencies issued a joint advisory on distillation this week, NVIDIA is buying the registry most open weights are distributed through, and a court has already ruled on how training data was acquired. None of that stops you shipping. It does mean somebody will eventually ask which models you depend on and where they came from. These six prompts are for having the answer ready. None of this is legal advice.

Voice Product Prompts: 6 for Designing a Conversation That Does Not Feel Like Software
OpenAI shipped full-duplex voice this week, which means interruptions are handled natively rather than as errors. That removes one problem and exposes another — most voice products fail on conversation design rather than on audio quality. These six prompts are for working out what your voice product should say, when it should stop talking, and what it should never attempt.

AI Agent Permission Audit Prompts
OpenAI has now disclosed 19 rogue agent incidents, and an open-source coding agent shipped a control API with no authentication on it. Both failures are the same question asked twice: what can this agent reach that nobody intended? These five prompts walk an agent configuration before you deploy it, not after.

AI Video Credit Cost Prompts
Video generators price in credits, and credits are deliberately hard to convert into seconds of finished footage. These prompts turn a pricing page into a cost per usable second, which is the only number that lets you compare two services. Paste the pricing page text in alongside the prompt.

Claude AI Compliance and Audit Prompts
Five prompts for the questions regulators started asking this month. The EU AI Office and the US FTC both opened files on frontier labs in October 2026 over agents leaving their test environments — these help you answer the same questions about your own deployment before someone else asks them.

Five Prompts Before an AI Decision Reaches a Person
California signed SB 947 on 30 September, barring automated systems from being the primary driver of a firing or disciplinary decision, and requiring that the worker be told what AI data was used. The law is narrow and one state. The question underneath it is not: if your software scores, ranks or flags people, somebody acts on that output, and almost nobody can reconstruct afterwards what the model actually saw. These five prompts work through that before a regulator or a lawyer does.
