feat(prisma-cloud)!: prisma deploy stops copying secrets from your local environment to Prisma Cloud, and fails only when a service needs a missing one - #426
An app whose email service reads two platform secrets: an API key it cannot run without, and a webhook secret it can do without.
// module.tsexportdefaultappRoot('shop',({ provision })=>{provision(emailService(),{input: {apiKey: envSecret('EMAIL_API_KEY'),// the service's schema requires itwebhookSecret: envSecret('EMAIL_WEBHOOK_SECRET'),// the service's schema makes it optional},});});
The developer has both values in .env. Neither is set on Prisma Cloud yet.
Before this PR, prisma deploy copied both values from .env to the project on Prisma Cloud, then deployed. The developer's local values were now the deployed values, in whichever environment they deployed to.
After this PR, prisma deploy copies nothing. It stops before creating any service or database, and says what to set:
Deploy failed. 1 platform variable a service needs has no value:
- EMAIL_API_KEY (read by service "shop.email", field "apiKey")
Set it on the platform, then deploy again:
- prisma project env add 'EMAIL_API_KEY=<value>' --project 'proj_…' --role production
Once EMAIL_API_KEY is set, the deploy goes through. The optional EMAIL_WEBHOOK_SECRET does not block it; the deploy lists it and carries on:
✔ check environment variables
Platform variables with no value:
- EMAIL_WEBHOOK_SECRET (read by service "shop.email", field "webhookSecret")
prisma project env add 'EMAIL_WEBHOOK_SECRET=<value>' --project 'proj_…' --role production
The decision
prisma deploy stops copying platform variables from the developer's local environment to Prisma Cloud implicitly. For now, the operator sets each one on Prisma Cloud with prisma project env add, and the deploy checks that the values the app's services need are there. It decides "need" from each service's own input schema, not from a value.
This is a choice about implicit copying, not a rule that the deploy may never set a variable. We expect to add an explicit way to set variables through deploy later, where the operator says which values go to which environment.
Why
A platform variable is a value the operator keeps on Prisma Cloud and a service reads when it starts: an API key, a signing secret. Until now, envSecret('NAME') told the deploy two things: the service reads NAME from the platform, and if the platform has no NAME yet, copy it from the developer's .env or shell. That copying has two problems.
A local value reaches a deployed environment..env is read for every environment. A developer who deploys to production with a test key in .env puts the test key in production, and nothing tells them.
It produced one copy per preview branch. Every deploy to a preview environment wrote that branch's own copy of each value. A project that used envSecret() on previews holds one copy per branch and usually no shared preview value, so every new branch depends on another copy being written.
Both problems come from the copy being implicit: the deploy guesses that a local value is meant for the remote environment. So the implicit copy goes. Until an explicit way exists, the operator sets each value once, at the scope they choose.
How it works now
The rest of this description builds that up step by step: how a variable is named, how a service points at it, what the deploy checks, and what the service sees when it starts.
1. A name is checked when the app loads.envSecret() and envParam() share one rule: a name is an upper-case letter followed by upper-case letters, digits and underscores (^[A-Z][A-Z0-9_]*$). Prisma Cloud itself refuses any other key, so a lower-case name could never have worked when deployed. A leading underscore is refused because shells and runtimes use such names for their own variables. COMPOSER_…, DATABASE_URL, DATABASE_URL_POOLED, PORT, PATH and HOME are reserved, each with its reason in the error. One name also has one meaning in an app: an envParam('X') and a root input field X cannot both exist. These checks run after Load in deploy, destroy and prisma dev, through a new extension hook, checkGraph.
2. The service's input document points at the variable. The deploy writes each service an input document: its input, with a marker wherever a platform variable's value goes. The marker is now { "$platform": { "name": "EMAIL_API_KEY", "secret": true } }, replacing { "$secret": "EMAIL_API_KEY" }. The format lives in one new package, @internal/input-document, which the deploy, the service at boot and the local prisma dev target all use, so the three cannot drift.
3. The deploy checks whether each variable has a value, without reading it. In its preflight step, the deploy lists each variable the app names on Prisma Cloud: one list call per name, at most eight at a time. A preview environment sees two rows: the value shared by every preview branch, and its own branch's override. The branch's row wins, as it does on the platform. Preflight writes no variable. A row that Prisma Cloud manages itself fails the deploy, because the app cannot own that name.
4. A missing variable fails the deploy only if a service needs it. For each service with a missing variable, preflight resolves the service's input with the missing variables left out and runs the service's own schema, exactly as the service will when it starts. If the schema accepts it, the variables were optional: the deploy lists them and goes on. If not, the variables whose absence alone fails the schema are required, and the deploy stops before creating any service or database. A per-key param bound to envParam() is required when it has no default and is not optional. This is the method prisma dev already used (ADR-0058); both now share it.
5. The operator sees every variable with no value. The list prints right after the preflight step and again at the end of the deploy report, with the service and field that read each one, and the command that sets it. For production the command uses --role production. For any other environment it leads with --role preview, the value shared by every preview branch, so the next branch works too, and then gives the --branch form for one branch only. Values never appear in the list: it holds names, readers and commands, and goes through redaction like everything else the CLI prints.
6. A changed value redeploys exactly the services that read it. Each service's deployment triggers include the updatedAt of the row it resolves for each variable it reads. Changing a value on the platform and deploying again replaces those services' deployments and no others.
7. At boot, a missing value is left out, and the service's schema decides. When a service starts, each marker is replaced with the variable's value. A variable with no value, or an empty one, leaves its key out, and the service's schema decides whether that is allowed. If it is not, the error names the variables that had no value; it never contains a value. A per-key param with no value takes its default. A marker inside an array cannot be left out, so a missing value there fails boot and is required at deploy.
8. prisma dev follows the same rules. It reads values from .env.dev, .env.dev.local and the shell, as before. A required variable with no value stops dev before any service starts. An optional one is left out, the same as on the platform. Each local service still receives only the variables it reads.
What changes for you
Do this once, before you deploy with this version. Your project probably has one copy of each envSecret() value per preview branch and no shared preview value. After this change, a new preview branch gets no copy. For each name your app reads with envSecret() or a per-key envParam(), create the shared preview value:
Production already holds its value from earlier deploys.
Then, each change, before and after:
The deploy no longer copies a missing variable. Before: a missing value was copied from your secrets or config adapters, by default your shell and .env. After: set it with prisma project env add. The failure and the list give the exact command.
A new app's first deploy stops at preflight if a service needs a variable. Preflight runs after the deploy has created the project, so the first deploy creates the project, then stops with the commands, including the new project id. Set the variables and deploy again.
Only a variable a service needs fails the deploy. Before: every missing variable that the adapters could not supply failed it. After: an optional one is listed and the deploy succeeds.
Names are upper case, and PORT, PATH and HOME are reserved. Load refuses anything else, in deploy, destroy and prisma dev.
A lower-case name must be renamed. It only ever worked under prisma dev, because the platform refuses lower-case keys, so no platform row needs to change.
A name with a leading underscore must be renamed. The platform accepts it, so a row may exist. Create the row under the new name in every scope that has the old one, then rename it in your code and deploy, then delete the old rows.
An unset per-key param with a default now boots. Before: it failed boot even with a default. After: it takes the default, or is left out when optional.
Empty means unset. An empty value is treated as no value, at boot and under prisma dev.
envParam() in an input binding is deprecated. Use a field of the root's input instead. A per-key param bound to envParam() is not deprecated, but editors strike it through too until it gets its own export.
Destroying production deletes the variables.prisma destroy for production removes the project and every variable set on it, as before. The deploy no longer writes them back, so set them again after the next deploy.
Prisma Cloud still reports a service that exits at boot as running and promotes it. If a service fails at boot, its error is in prisma service logs <service> --project <project id>.
How it was checked
On Prisma Cloud, by hand, in throwaway projects that were all destroyed afterwards:
A required secret with no value: the deploy stopped before any service or database, with the variable, its reader and the command. The platform's rows were the same before and after.
Set, then deployed again: the service received the value.
Optional secrets with no value: the deploy succeeded and listed them in both places.
A fresh preview branch with only a shared preview value: the service received it.
A changed branch row redeployed only the service that reads it. A changed shared row under a branch override redeployed nothing.
A planted secret appeared nowhere: not in the deploy output, the reports, the stack file, the Alchemy log or the hosted state.
Under prisma dev: a required secret with no value stopped dev, and each service received only its own variables.
In CI: the storefront-auth deploy job now takes the path a new app takes. Its first deploy must stop at preflight naming AUTH_SIGNING_SECRET, a script sets the value on the platform, and the second deploy must succeed.
Reviews: two rounds of design and code review; every finding is fixed or recorded in the project's deferred.md.
Records: ADR-0064 is new. ADR-0029, 0032, 0042, 0058 and 0062, the glossary, the goals, the deploy and app-building guides and the core-concepts skill are updated to match.
Spec: slices/2-the-deploy-fills-nothing/spec.md. Design: design.md. This is slice 2 of 4 in the platform-variables project; slice 3 adds a platform variable as a node in the app's graph, under these same rules.
Alternatives considered
Keep copying implicitly on deploy. Rejected: because .env is read for every environment, an implicit copy is how a developer's local value reaches production.
An explicit way to set variables through deploy now. Not in this PR: it needs its own design for how the operator names the values and the environments they go to. We expect to add it later; until then, prisma project env add sets a value at any scope.
Let the deploy succeed with every variable missing, and only list them. Rejected: Prisma Cloud promotes a service that crashes at boot and reports it as running, so the deploy would leave a broken service live with no error.
… boot leaves an unset variable out
A new package, @internal/input-document, holds the marker format, the key escape, the marker walk and the boot error texts. The serializer, boot and the local target all import it, and the local target's copies of the constants are gone.
- The serializer writes { "$platform": { "name": "X", "secret": true } } where it wrote { "$secret": "X" }. The key escape covers $platform, $generated and $secret.
- Only $generated names must be distinct. Two envSecret() leaves of one name in one binding are allowed.
- InputDocumentRow.secrets becomes variables (name and secret flag). The deploy report shows a marker as $platform NAME or $generated NAME.
- Boot leaves out the key of a marker whose variable is unset or empty, fails for one in an array position, boxes a secret, and ends a schema failure with the unset names.
- A per-key envParam() param whose variable is unset or empty takes its default, is left out when optional, and fails only when required, with an error that says to set the variable.

…xtension graph check after Load
Core: ExtensionDescriptor gains an optional checkGraph(graph). runPipeline calls every extension's checkGraph right after Load, once the known secrets are added and before registry coverage, so it runs for deploy, destroy, dev's first start and every dev rebuild. A throw fails the command as COMPOSE.GRAPH_INVALID with the hook's message. resolveAppIdentity does not call it.
Prisma Cloud: assertVariableName(name, factory) refuses a name that does not match ^[A-Z][A-Z0-9_]*$ and the reserved names COMPOSER_..., DATABASE_URL, DATABASE_URL_POOLED, PORT, PATH and HOME, each with its reason. envSecret() and envParam() call it and lose their own copies. prismaCloud() registers a checkGraph that refuses one name used by envParam() and by a root input field, naming both.
The preflight test that bound one name as a secret and as an env-sourced param goes: Load refuses that graph, and it tested seeding.

…ly for one a service needs
Preflight no longer creates a missing platform variable from the app secrets or the app configuration: fillMissing, its POST and every seeding test are gone. A test proves POST /v1/environment-variables is never called.
- One list call per name, filtered by project, class and key, walked to its last page, at most eight at a time through a small mapWithConcurrency helper. The environment sees the class row (no branch) and, for a preview environment, its own branch row. A failed list call still fails the deploy.
- The branch row wins when present, otherwise the class row; the updatedAt handed back is that row's, so a newer class row under a branch override changes nothing.
- A row the environment sees with isManagedBySystem fails the deploy naming the variable.
- The ADR-0058 method moves from the dev preflight to required-variables.ts, and both preflights call it; dev behaves as before. Deploy runs it per service with every unset variable; a variable in an array position is required without a check; a per-key envParam() param is required when it has no default and is not optional; a secret in a module input no service reads is reported, never required.
- A required variable fails the deploy with each reader and the commands: --role production for production, otherwise --role preview then --role preview --branch.
- Preflight returns { updatedAt, findings }. Core gains PreflightFindings (the unset variables nothing requires, with readers and commands), its guard and the reader text. The deploy payload on the preflight transport becomes { updatedAt, findings }, and TransportedPreflight exposes findings in the alchemy process. report() now gives { checked, unset }.
- architecture.config.json classifies the new files and the two D2 left out (graph-check.ts, variable-name.ts).

…value, and prisma dev needs only a required per-key param
PreflightInput.report now takes a PreflightReport: how many variables preflight checked and the findings (names and readers only, never a value). The Prisma Cloud preflight reports once, when it passes.
- Deploy keeps flat step data { checked, unset } and, when the list is not empty, emits a new preflight-findings event right after the preflight step. The human renderer prints it as the "Platform variables with no value:" block; JSON carries it as a message whose data is the findings.
- ExtensionDescriptor gains preflightFindings(): in the alchemy process the Prisma Cloud extension returns what its transport carried. Lowering adds every extension's findings to DeploymentResult, and renderDeployment repeats the block at the end of the deploy report. One CLI function formats the block for both.
- The dev preflight fails for an unset or empty per-key envParam() param only when it has no default and is not optional, naming each reader as the deploy does. collectPreflightNames, now unused, goes.
- envParam() is marked @deprecated: a root input field replaces it in a binding; per-key params are unchanged.

…report, and both preflights name an unset array position
- Core carries the platform variables with no value to the second process in its own variable, PRISMA_COMPOSER_DEPLOY_FINDINGS, and lowering reads it into DeploymentResult.findings. The preflightFindings hook and the findings member of the Prisma Cloud preflight payload are gone; the payload holds updatedAt only.
- PreflightReport is now PlatformVariableCheck, and its doc comment says it carries platform-variable findings and a count, nothing else.
- The serializer returns every $platform marker with its path and whether an array position holds it. requiredVariables uses them, so the dev preflight now names a variable an array position reads, and the service. One type each for the verdict (RequirementCheck), a missing variable (MissingVariables), the resolved row (ResolvedRow) and the deploy payload.
- The dev error says "platform variable", like the deploy error. The serializer names the variable when an array position has none.
- checkGraph refuses with core's GraphCheckError; any other throw reaches the user as a bug.
- configKey uses composerKey. The name error says the leading-underscore rule is Composer's.
- bounded-concurrency.ts is map-with-concurrency.ts.
- The first e2e deploy must fail with the preflight error itself.

This PR replaces the implicit copy of platform variables from the developer's local environment with an explicit preflight check: prisma deploy no longer pushes .env/shell values to Prisma Cloud, and instead verifies — without reading values — that every variable each service's input schema requires has a value on the platform, failing before any service or database is created and telling the operator exactly what to set with prisma project env add.
Variable naming and validation.envSecret() and envParam() now enforce one name rule (^[A-Z][A-Z0-9_]*$), refuse leading underscores, reserve COMPOSER_*, DATABASE_URL*, PORT, PATH and HOME with per-name reasons, and reject collisions between an envParam() name and a root input field. The checks run after Load through a new checkGraph extension hook shared by deploy, destroy and prisma dev, so all three entry points reject bad names consistently.
Shared input-document format. The { "$secret": "NAME" } marker becomes { "$platform": { "name", "secret" } }, defined once in the new @internal/input-document package and consumed by the deploy, the service at boot, and prisma dev, which structurally prevents the three from drifting. At boot a missing or empty value leaves its key out and the service's schema decides; a per-key param takes its default; a marker inside an array cannot be omitted and is therefore required at deploy.
Preflight and redeploy semantics. The preflight lists one row per name (shared preview row plus branch override, branch winning, at most eight lookups in flight), fails only when a service's own schema rejects the missing variables, and prints the missing list with readers and set-commands both after preflight and in the deploy report, redacted like all CLI output. Deployment triggers now include the updatedAt of the resolved row, so changing a value redeploys exactly the services that read it.
Local dev parity.prisma dev adopts the same required/optional decision (ADR-0058's method), stopping before any service starts when a required variable is unset, treating empty as unset, and still giving each service only the variables it reads.
Test alignment. The integration assertion in local-dev-criteria-4-5.integration.ts:281 was updated from "required by service" to "read by service", matching the actual preflight phrasing produced by platformVariableReaderText and missing-variables-text.ts — a stale-regex fix consistent with the deploy and local-target preflight tests' expectations.

Summary by CodeRabbit
New Features
Deploy preflight now checks for platform variables without creating or filling them. Missing variables block deployment only when required; optional or unused variables are reported with guidance for setting them.
Deployment reports include unset-variable findings and identify the services or parameters that read them.
Unset or empty platform variables are omitted at boot, with defaults and schema rules determining whether the app can continue.
Added guidance for managing platform variables across production and preview environments, including the effects of deleting a production environment.
Bug Fixes
Improved validation of platform-variable names and detection of conflicting configuration.
Redacted values remain protected while literal placeholders in command output are preserved.
Walkthrough
The pull request changes platform variables from deploy-filled values to operator-managed values. Deploy preflight now reads variable rows, fails only for required missing values, and reports optional or unused missing values. Input documents use $platform markers, with shared boot-time resolution and omission rules. Graph checks, variable-name validation, findings transport, CLI reporting, local development behavior, CI setup, tests, and documentation are updated accordingly.

Lowering reads the preflight findings at the start, next to the
containers, so a value that does not decode fails before anything is
applied. The findings variable is PRISMA_COMPOSER_PREFLIGHT_FINDINGS, and
no extension preflight variable may take that name.
The array-position error says an envParam() value comes from the app
configuration, not the platform. The deploy prints the reason for a
variable an array position or a per-key param requires, and the
schema message for a service that needs some of several variables.
requiredVariables is checkRequirements. A graph check refusal carries
the refusing extension id in meta.extension.
The glossary, ADR-0058, ADR-0064 and local-dev.md match the current dev
preflight. The deploy guide and the destroy log say that destroying
production deletes the project with every platform variable set on it.

…ndom challenge
The auth service hard-coded the value CI set for AUTH_SIGNING_SECRET and returned whether the two matched. Now each CI run generates a random value for each platform variable, and auth exposes sign(), which returns the HMAC-SHA256 of a challenge keyed with the signing key. The storefront page renders the signature for a challenge query parameter. The verify, now a TypeScript script, sends a random challenge and compares the signature with one it computes from the same secret.

At a glance
An app whose email service reads two platform secrets: an API key it cannot run without, and a webhook secret it can do without.
The developer has both values in
.env. Neither is set on Prisma Cloud yet.Before this PR,
prisma deploycopied both values from.envto the project on Prisma Cloud, then deployed. The developer's local values were now the deployed values, in whichever environment they deployed to.After this PR,
prisma deploycopies nothing. It stops before creating any service or database, and says what to set:Once
EMAIL_API_KEYis set, the deploy goes through. The optionalEMAIL_WEBHOOK_SECRETdoes not block it; the deploy lists it and carries on:The decision
prisma deploystops copying platform variables from the developer's local environment to Prisma Cloud implicitly. For now, the operator sets each one on Prisma Cloud withprisma project env add, and the deploy checks that the values the app's services need are there. It decides "need" from each service's own input schema, not from a value.This is a choice about implicit copying, not a rule that the deploy may never set a variable. We expect to add an explicit way to set variables through
deploylater, where the operator says which values go to which environment.Why
A platform variable is a value the operator keeps on Prisma Cloud and a service reads when it starts: an API key, a signing secret. Until now,
envSecret('NAME')told the deploy two things: the service readsNAMEfrom the platform, and if the platform has noNAMEyet, copy it from the developer's.envor shell. That copying has two problems..envis read for every environment. A developer who deploys to production with a test key in.envputs the test key in production, and nothing tells them.envSecret()on previews holds one copy per branch and usually no shared preview value, so every new branch depends on another copy being written.Both problems come from the copy being implicit: the deploy guesses that a local value is meant for the remote environment. So the implicit copy goes. Until an explicit way exists, the operator sets each value once, at the scope they choose.
How it works now
The rest of this description builds that up step by step: how a variable is named, how a service points at it, what the deploy checks, and what the service sees when it starts.
1. A name is checked when the app loads.
envSecret()andenvParam()share one rule: a name is an upper-case letter followed by upper-case letters, digits and underscores (^[A-Z][A-Z0-9_]*$). Prisma Cloud itself refuses any other key, so a lower-case name could never have worked when deployed. A leading underscore is refused because shells and runtimes use such names for their own variables.COMPOSER_…,DATABASE_URL,DATABASE_URL_POOLED,PORT,PATHandHOMEare reserved, each with its reason in the error. One name also has one meaning in an app: anenvParam('X')and a root input fieldXcannot both exist. These checks run after Load indeploy,destroyandprisma dev, through a new extension hook,checkGraph.2. The service's input document points at the variable. The deploy writes each service an input document: its input, with a marker wherever a platform variable's value goes. The marker is now
{ "$platform": { "name": "EMAIL_API_KEY", "secret": true } }, replacing{ "$secret": "EMAIL_API_KEY" }. The format lives in one new package,@internal/input-document, which the deploy, the service at boot and the localprisma devtarget all use, so the three cannot drift.3. The deploy checks whether each variable has a value, without reading it. In its preflight step, the deploy lists each variable the app names on Prisma Cloud: one list call per name, at most eight at a time. A preview environment sees two rows: the value shared by every preview branch, and its own branch's override. The branch's row wins, as it does on the platform. Preflight writes no variable. A row that Prisma Cloud manages itself fails the deploy, because the app cannot own that name.
4. A missing variable fails the deploy only if a service needs it. For each service with a missing variable, preflight resolves the service's input with the missing variables left out and runs the service's own schema, exactly as the service will when it starts. If the schema accepts it, the variables were optional: the deploy lists them and goes on. If not, the variables whose absence alone fails the schema are required, and the deploy stops before creating any service or database. A per-key param bound to
envParam()is required when it has no default and is not optional. This is the methodprisma devalready used (ADR-0058); both now share it.5. The operator sees every variable with no value. The list prints right after the preflight step and again at the end of the deploy report, with the service and field that read each one, and the command that sets it. For production the command uses
--role production. For any other environment it leads with--role preview, the value shared by every preview branch, so the next branch works too, and then gives the--branchform for one branch only. Values never appear in the list: it holds names, readers and commands, and goes through redaction like everything else the CLI prints.6. A changed value redeploys exactly the services that read it. Each service's deployment triggers include the
updatedAtof the row it resolves for each variable it reads. Changing a value on the platform and deploying again replaces those services' deployments and no others.7. At boot, a missing value is left out, and the service's schema decides. When a service starts, each marker is replaced with the variable's value. A variable with no value, or an empty one, leaves its key out, and the service's schema decides whether that is allowed. If it is not, the error names the variables that had no value; it never contains a value. A per-key param with no value takes its default. A marker inside an array cannot be left out, so a missing value there fails boot and is required at deploy.
8.
prisma devfollows the same rules. It reads values from.env.dev,.env.dev.localand the shell, as before. A required variable with no value stops dev before any service starts. An optional one is left out, the same as on the platform. Each local service still receives only the variables it reads.What changes for you
Do this once, before you deploy with this version. Your project probably has one copy of each
envSecret()value per preview branch and no shared preview value. After this change, a new preview branch gets no copy. For each name your app reads withenvSecret()or a per-keyenvParam(), create the shared preview value:Production already holds its value from earlier deploys.
Then, each change, before and after:
secretsorconfigadapters, by default your shell and.env. After: set it withprisma project env add. The failure and the list give the exact command.PORT,PATHandHOMEare reserved. Load refuses anything else, indeploy,destroyandprisma dev.prisma dev, because the platform refuses lower-case keys, so no platform row needs to change.prisma dev.envParam()in an input binding is deprecated. Use a field of the root'sinputinstead. A per-key param bound toenvParam()is not deprecated, but editors strike it through too until it gets its own export.prisma destroyfor production removes the project and every variable set on it, as before. The deploy no longer writes them back, so set them again after the next deploy.Prisma Cloud still reports a service that exits at boot as running and promotes it. If a service fails at boot, its error is in
prisma service logs <service> --project <project id>.How it was checked
prisma dev: a required secret with no value stopped dev, and each service received only its own variables.AUTH_SIGNING_SECRET, a script sets the value on the platform, and the second deploy must succeed.deferred.md.Records: ADR-0064 is new. ADR-0029, 0032, 0042, 0058 and 0062, the glossary, the goals, the deploy and app-building guides and the core-concepts skill are updated to match.
Spec:
slices/2-the-deploy-fills-nothing/spec.md. Design:design.md. This is slice 2 of 4 in the platform-variables project; slice 3 adds a platform variable as a node in the app's graph, under these same rules.Alternatives considered
.envis read for every environment, an implicit copy is how a developer's local value reaches production.deploynow. Not in this PR: it needs its own design for how the operator names the values and the environments they go to. We expect to add it later; until then,prisma project env addsets a value at any scope.Agent: hipparchus-99
