Flows

What Flows just did

Based on your request to build Assemble Tool Prompts Dynamically per Environment, Flows created 4 implementation stages and 12 checks.

You asked for: Replace static tool prompts with a generator that assembles blocks conditionally from the live environment and measures the token cost of every block.. Flows generated 4 stages because the application requires A prompt generator function per tool, not a static string; Feature-gated blocks: sandbox, background tasks, git protocols included only when active; Live config (allowed paths, hosts, limits) injected from the source of truth, deduped. Each stage tells your AI builder what to do, tests whether it actually worked, and gives a repair instruction when it fails. These checks are designed to catch: A static prompt describing sandbox rules while sandboxing is off, teaching the model false constraints; Config duplicated from multiple sources bloating every request by hundreds of tokens; Prompt and enforcement drifting apart because values are hand-copied.

Example failure

The form reported success, but no database record was created.

What Flows does

Flows detects the failure, generates a repair instruction, reruns the test, and stores the passing evidence.

Copy to external builder

Copies a prompt for Claude/Cursor/etc. Records prompt_copied only — not execution, commits, or checks.

Execute through Oort

Requires Sign in with Oort + a provider connection (BYOK). Keys stay on Oort. A model name in the dropdown is not the same as a live connection.

Next

Check off: Every section has an explicit condition

Add a proof note on each check — a checkbox alone is weak proof.

Probes & advanced tools are under “More verification tools”. Experience level: Settings.

App persistence (create → read → assert token)

Body template: {"probe":"{{token}}","title":"flows-probe-{{token}}"}. Needs CORS-readable public create/list endpoints (or inconclusive). Badge only when create→read→refresh finds the token (detects false success).

Two-account authorization (User B cannot see/change User A)

Authorization evidence source: Cross-account ownership test (trust level 5/6). These are not equivalent. Unauthenticated probe alone is weaker (source: unauthenticated API probe). Tokens stay in this browser session only — not uploaded to Flows servers.

Generated edge-case tests (review / approve)

  • api_probe Submitting the form empty is rejected with a clear error
  • api_probe Each required field can be omitted and fails validation
  • api_probe Malformed email is rejected
  • api_probe Malformed phone is rejected when phone is collected
  • api_probe Duplicate submission does not create two records
  • api_probe Double-click submit creates only one record
  • false_success_probe Failed request does not show success
  • browser_automation Refresh during submission does not leave corrupt state
  • api_probe Oversized input is rejected
  • api_probe Unsafe strings do not execute or break storage
  • api_probe Create then refresh still shows the record
  • api_probe Edit then refresh keeps the edit
  • api_probe Delete then refresh removes the record
  • api_probe Nonexistent record ID fails cleanly
  • cross_account_probe Cross-user record identifier is rejected

Generated from this route’s signals — you approve; you do not invent security tests.

Content probe (GET body contains text)

In-product content probe reads response text when CORS allows — not full DOM/click automation. Playwright script is optional and external.

How this plan was created

Plan from project details

Flows creates steps using the goal, requirements, stack, platform, and details you provide.

  • Project description
  • Selected template / route
  • User-entered stack
  • Constraints and notes
  • Assemble Tool Prompts Dynamically per Environment

No repository inspection implied. Connect and inspect a codebase to ground steps in real files.

Plan instructions

Use these instructions in Claude, ChatGPT, Cursor, Emergent, or another builder.

List every section of your current tool/system prompt and mark its activation condition: ALWAYS (core tool description), FEATURE-GATED (sandbox instructions only if sandboxing is enabled; background-task instructions only if background execution is allowed; git safety protocol only in repos), ENVIRONMENT-DERIVED (allowed paths, network hosts, resource limits - values that come from live config), and AUDIENCE (internal power users may get short skill references where external users need full inline instructions). For each block record: condition, source of truth for its values, and current token cost. This map is the spec for the generator.

The AI tool writes code — Flows only organizes the plan · Complete implementation prompt with explicit requirements

Project context

Copies the project goal, technical details, current step, previous progress, and checks so your AI tool understands what it is working on.

Expected after this step

A block map: prompt section, activation condition, value source, token cost.

Should not happen

  • A static prompt describing sandbox rules while sandboxing is off, teaching the model false constraints
  • Config duplicated from multiple sources bloating every request by hundreds of tokens
  • Prompt and enforcement drifting apart because values are hand-copied
  • No measurement, so prompt bloat accumulates invisibly

Verify gate — prove this step works before continuing

Do not move on until every check is true. Add proof notes — a checked box alone is weak proof. Checks are manual by default; deploy/API probes live under “More verification tools” and do not auto-check boxes.

Do not continue if…

  • !A static prompt describing sandbox rules while sandboxing is off, teaching the model false constraints
  • !Config duplicated from multiple sources bloating every request by hundreds of tokens
  • !Prompt and enforcement drifting apart because values are hand-copied
  • !No measurement, so prompt bloat accumulates invisibly

Repair path — if this step fails

Use the Repair Prompt when a verify gate fails. Loop: Detected → Diagnosed → Repair issued → Changed → Retested → Resolved

Show repair prompt textShow

Everything got marked ALWAYS. Challenge each block: would this text be wrong or wasted in any deployment (sandbox off, no git repo, feature flag off)? If yes, it is conditional - static-by-default is how prompts rot.

Your notes for this step

Definition of Done

Final route-level requirements. Manual checks — separate from per-step verify gates. Completing step gates does not auto-check these. Route completion is not a production-ready claim.
