A generic product prompt may describe the desired application correctly while still being unsuitable for the environment that must build it. This method adds an adaptation stage between specification and implementation. Name the target platform, research how it currently works, and identify practical issues such as API-key setup, connector availability, social-platform access, hosting, file persistence, or deployment support. Ask the model to translate these findings into platform-specific instructions and strategies for overcoming known limitations. The resulting prompt should retain the product's intended user flow while changing implementation details to match the environment. This reduces avoidable failures, reveals where external integrations are required, and allows the builder to make an informed judgment about whether to proceed, simplify the MVP, or switch tools.
Origin
Kieran Flanagan articulated this correction after initially prompting without telling Claude that the application would be built in Perplexity Computer.
Core principles
- 01Name the target platform before implementation begins
- 02Research the platform's current capabilities and constraints
- 03Convert platform limitations into explicit prompt guidance
- 04Choose integrations according to actual platform access
- 05Treat a platform-agnostic specification as an intermediate artifact
How to run it
- 1
Choose the target environment
Specify the coding agent, application builder, or agent platform that will perform the implementation. Do this before requesting final build instructions.
Pro tip Include the expected deployment and runtime environment as well as the builder.
Watch out Two tools may support similar prompts while exposing very different capabilities.
- 2
Research current capabilities
Investigate the platform's files, connectors, APIs, deployment options, persistence, and known limitations. Prefer current information because AI products change rapidly.
Pro tip Ask the model to distinguish confirmed features from assumptions.
Watch out Do not rely on stale knowledge about fast-moving AI products.
- 3
Identify gotchas
List constraints that could break or weaken the specification, such as restricted LinkedIn access or missing API keys. Connect each constraint to the affected feature.
Pro tip Prioritize blockers that affect the core user journey.
Watch out Minor polish issues should not distract from fundamental data-access problems.
- 4
Design workarounds or scope changes
For each important limitation, select a connector, API, manual fallback, reduced scope, or alternative platform. Make the trade-off explicit.
Pro tip Prefer an honest MVP limitation over fabricated or unreliable data.
Watch out A workaround that violates platform terms or user privacy is not acceptable.
- 5
Rewrite and validate the prompt
Generate implementation instructions tailored to the platform and test whether the output behaves as expected. Revise using observed failures rather than generic prompting advice.
Pro tip Include the target platform's terminology and available primitives.
Watch out Do not assume a successful prototype proves every integration path.
In the wild
After receiving a generic specification, Kieran recognized that the prompt should first have asked Claude to research Perplexity Computer. The revised process sought platform-specific gotchas and ways to overcome them before sending the build prompt into Computer.
→ The team produced and deployed a working prototype despite earlier problems with Claude.
A builder researches whether the agent can host applications, retain files, call authenticated APIs, and continue tasks when the laptop closes. Unsupported features are moved behind external services before implementation begins.
→ The final prompt requests only capabilities the environment can reliably deliver.
Common mistakes
Hiding the target platform
Without the implementation environment, the model may propose architectures and integrations that cannot run there.
Researching after the build fails
Platform discovery is cheaper before implementation than after the application depends on unsupported capabilities.
Ignoring data-access constraints
Creator discovery can appear functional while returning weak results if the platform cannot access important networks or APIs.
Is it for you?
Best for
Builders moving an AI-generated specification into a particular coding agent, low-code environment, or hosted agent platform.
Not ideal for
Platform-independent conceptual work that will not yet be implemented.
From the transcript
“Obviously, you need to tell the platform you're building for. That was a bad prompt.”
“I could have just said to start with, go research perplexity computer and then craft a prompt for that tool.”
“And then you actually ask it to research the app you're going to build it in, which we said is perplexity computer, and then it…”
