From 6916aa4fa0067dcb5124ca297fa8648ec8b7e9fa Mon Sep 17 00:00:00 2001 From: Waleed Latif Date: Thu, 27 Aug 2026 11:45:39 -0700 Subject: [PATCH 1/5] improvement(tools): state every pinned param, not just the credential Two agent tools bound to the same Gmail account but different labels reached the model byte-identical: every param a user fills is stripped from the schema, and only the credential was ever named in the description. The model could not tell Inbox from Sent, and with a single tool it could promise a caller it would search a folder that tool can never reach. Each tool now states the values the workflow pinned on it, whether or not it has a duplicate sibling. Opaque resource ids still resolve to a display name; plain values like a label, a row limit or a toggle need no lookup and are stated directly. Secrets never are: a field marked `password`, a hidden field, a secret-named param, and every literal on a tool whose params resolved an environment variable are all withheld. --- .../executor/handlers/agent/agent-handler.ts | 8 +- .../executor/handlers/pi/local/sim-tools.ts | 10 +- .../utils/tool-binding-labels.test.ts | 256 ---------------- .../sim/executor/utils/tool-binding-labels.ts | 191 ------------ .../executor/utils/tool-pinned-params.test.ts | 225 ++++++++++++++ apps/sim/executor/utils/tool-pinned-params.ts | 155 ++++++++++ apps/sim/providers/tool-binding.test.ts | 289 ++++++++++++------ apps/sim/providers/tool-binding.ts | 206 ++++++++----- apps/sim/providers/utils.ts | 10 +- 9 files changed, 726 insertions(+), 624 deletions(-) delete mode 100644 apps/sim/executor/utils/tool-binding-labels.test.ts delete mode 100644 apps/sim/executor/utils/tool-binding-labels.ts create mode 100644 apps/sim/executor/utils/tool-pinned-params.test.ts create mode 100644 apps/sim/executor/utils/tool-pinned-params.ts diff --git a/apps/sim/executor/handlers/agent/agent-handler.ts b/apps/sim/executor/handlers/agent/agent-handler.ts index e6076426b24..c69889d083a 100644 --- a/apps/sim/executor/handlers/agent/agent-handler.ts +++ b/apps/sim/executor/handlers/agent/agent-handler.ts @@ -68,7 +68,7 @@ import type { ResolvedSecretInputPath, ResolvedSecretTraceRegistry, } from '@/executor/utils/resolved-secret-trace-registry' -import { annotateDuplicateToolBindings } from '@/executor/utils/tool-binding-labels' +import { annotateToolPinnedParams } from '@/executor/utils/tool-pinned-params' import { resolveVertexCredential } from '@/executor/utils/vertex-credential' import { executeProviderRequest } from '@/providers' import { @@ -808,7 +808,11 @@ export class AgentBlockHandler implements BlockHandler { const tools = allTools.filter( (tool): tool is ProviderToolConfig => tool !== null && tool !== undefined ) - await annotateDuplicateToolBindings(ctx, tools) + await annotateToolPinnedParams(ctx, tools, { + // A tool whose params resolved an environment secret must not have its literal values + // stated; the provenance map already identifies exactly those tools. + hasResolvedSecretInputs: (tool) => inputProvenance.has(tool), + }) return { tools, inputProvenance } } diff --git a/apps/sim/executor/handlers/pi/local/sim-tools.ts b/apps/sim/executor/handlers/pi/local/sim-tools.ts index fa55a7faa3f..056a2b94a06 100644 --- a/apps/sim/executor/handlers/pi/local/sim-tools.ts +++ b/apps/sim/executor/handlers/pi/local/sim-tools.ts @@ -16,7 +16,7 @@ import type { PiToolResult, PiToolSpec } from '@/executor/handlers/pi/core/backe import type { ExecutionContext } from '@/executor/types' import { projectResolvedSecretModelContent } from '@/executor/utils/resolved-secret-content-projection' import type { ResolvedSecretTraceRegistry } from '@/executor/utils/resolved-secret-trace-registry' -import { annotateDuplicateToolBindings } from '@/executor/utils/tool-binding-labels' +import { annotateToolPinnedParams } from '@/executor/utils/tool-pinned-params' import { assignProviderToolIdentities } from '@/providers/tool-identity' import type { ProviderToolConfig } from '@/providers/types' import { transformBlockTool } from '@/providers/utils' @@ -233,7 +233,13 @@ export async function buildSimToolSpecs( } const providers = configuredTools.map(({ provider }) => provider) - await annotateDuplicateToolBindings(ctx, providers) + // Pi resolves secret provenance per tool CALL rather than per format, so it cannot say which + // individual tool carries one.

A block's subblocks span every operation it supports, so a Gmail block switched from Send to Read still holds `to`, `subject` and `body` — and the tool stated them as constraints on a read tool, leaking stale draft content into the prompt. Literals are now filtered to the selected tool's declared params. Resources are exempt: an OAuth credential is a block input that never appears in a tool's param map. MCP tools carry configured params but have no subblocks, so they registered nothing and their pinned values went unstated. They now collect from their configured params directly. The duplicate hint claimed the copies differ whenever a tool had a sibling, even when both rendered identical text. It now compares the rendered statements, so the model is never told to pick between indistinguishable copies. Also: reuse `isPasswordParameter` instead of a second secret regex, applied only to literals since it matches `oauthCredential`; make the field type a real union so a field cannot be both a literal and a resource; and cut the stated-field cap from six to three, since every field costs tokens on every request in the loop. --- .../executor/handlers/agent/agent-handler.ts | 24 +- .../executor/handlers/pi/local/sim-tools.ts | 15 +- .../executor/utils/tool-pinned-params.test.ts | 145 ++++----- apps/sim/executor/utils/tool-pinned-params.ts | 144 +++++---- apps/sim/providers/tool-binding.test.ts | 296 +++++++++--------- apps/sim/providers/tool-binding.ts | 199 +++++++----- apps/sim/providers/utils.ts | 7 +- 7 files changed, 429 insertions(+), 401 deletions(-) diff --git a/apps/sim/executor/handlers/agent/agent-handler.ts b/apps/sim/executor/handlers/agent/agent-handler.ts index c69889d083a..f655b7f9a12 100644 --- a/apps/sim/executor/handlers/agent/agent-handler.ts +++ b/apps/sim/executor/handlers/agent/agent-handler.ts @@ -83,6 +83,7 @@ import { getInlineHydrationMaxBytes, } from '@/providers/file-attachments.server' import { isAutoModel, SIM_AUTO_MODEL_ID } from '@/providers/models' +import { collectPinnedFieldsFromParams, registerToolPinnedFields } from '@/providers/tool-binding' import { type ProviderToolInputProvenance, registerProviderToolInputProvenance, @@ -808,11 +809,9 @@ export class AgentBlockHandler implements BlockHandler { const tools = allTools.filter( (tool): tool is ProviderToolConfig => tool !== null && tool !== undefined ) - await annotateToolPinnedParams(ctx, tools, { - // A tool whose params resolved an environment secret must not have its literal values - // stated; the provenance map already identifies exactly those tools. - hasResolvedSecretInputs: (tool) => inputProvenance.has(tool), - }) + // A tool whose params resolved an environment secret must not have its literal values stated; + // the provenance map already identifies exactly those tools. + await annotateToolPinnedParams(ctx, tools, (tool) => inputProvenance.has(tool)) return { tools, inputProvenance } } @@ -1378,13 +1377,26 @@ export class AgentBlockHandler implements BlockHandler { const filteredSchema = filterSchemaForLLM(config.schema, config.userProvidedParams) const toolId = createMcpToolId(config.serverId, config.toolName) - return { + const mcpTool = { id: toolId, description: config.description, parameters: filteredSchema, params: config.userProvidedParams, usageControl: config.usageControl || 'auto', } + + // An MCP tool has no block subblocks to describe it, so its pinned params are read straight + // from the configured values, keyed by the remote schema's own names. + const { formatParameterLabel, isPasswordParameter } = await import('@/tools/params') + registerToolPinnedFields( + mcpTool, + collectPinnedFieldsFromParams(config.userProvidedParams, { + formatParamLabel: formatParameterLabel, + isPasswordParam: isPasswordParameter, + }) + ) + + return mcpTool } private async transformBlockTool( diff --git a/apps/sim/executor/handlers/pi/local/sim-tools.ts b/apps/sim/executor/handlers/pi/local/sim-tools.ts index 056a2b94a06..d7cf7fcb5ce 100644 --- a/apps/sim/executor/handlers/pi/local/sim-tools.ts +++ b/apps/sim/executor/handlers/pi/local/sim-tools.ts @@ -233,13 +233,16 @@ export async function buildSimToolSpecs( } const providers = configuredTools.map(({ provider }) => provider) - // Pi resolves secret provenance per tool CALL rather than per format, so it cannot say which - // individual tool carries one.

That is the exact assertion the comparison exists to prevent. The duplicate check now compares the un-withheld render, so disclosure differences no longer read as configuration differences. Also drops a redundant copy of the resolved-name cache, returns undefined rather than an empty-string sentinel for an unresolved resource, unexports two internal-only interfaces, and corrects six comments: five overstated or referenced the module this branch renamed, and one described the wrong failure mode for a credential entered in advanced mode. Adds the uncovered branches the review named: canonical-id grouping (the shape production actually sees once wire ids are aliased), a sibling that states nothing, negative-cache reuse, both resource kinds in one pass, an omitted tool param map, empty and oversized titles, and a non-finite number. --- .../executor/handlers/agent/agent-handler.ts | 2 - .../executor/utils/tool-pinned-params.test.ts | 73 +++++++++++++++++++ apps/sim/executor/utils/tool-pinned-params.ts | 73 +++++++++++-------- apps/sim/providers/tool-binding.test.ts | 46 ++++++++++++ apps/sim/providers/tool-binding.ts | 17 +++-- apps/sim/providers/utils.ts | 2 +- 6 files changed, 171 insertions(+), 42 deletions(-) diff --git a/apps/sim/executor/handlers/agent/agent-handler.ts b/apps/sim/executor/handlers/agent/agent-handler.ts index f655b7f9a12..39adfadf84d 100644 --- a/apps/sim/executor/handlers/agent/agent-handler.ts +++ b/apps/sim/executor/handlers/agent/agent-handler.ts @@ -1385,8 +1385,6 @@ export class AgentBlockHandler implements BlockHandler { usageControl: config.usageControl || 'auto', } - // An MCP tool has no block subblocks to describe it, so its pinned params are read straight - // from the configured values, keyed by the remote schema's own names. const { formatParameterLabel, isPasswordParameter } = await import('@/tools/params') registerToolPinnedFields( mcpTool, diff --git a/apps/sim/executor/utils/tool-pinned-params.test.ts b/apps/sim/executor/utils/tool-pinned-params.test.ts index 827d03b1529..672acc67930 100644 --- a/apps/sim/executor/utils/tool-pinned-params.test.ts +++ b/apps/sim/executor/utils/tool-pinned-params.test.ts @@ -190,6 +190,79 @@ describe('annotateToolPinnedParams', () => { expect(appended(second[0])).toContain('Gmail Account "Support Inbox"') }) + it('does not claim copies differ when only their secret disclosure does', async () => { + const open = providerTool('gmail_read_email', [account('cred-a'), label('INBOX')]) + const secret = providerTool('gmail_read_email', [account('cred-a'), label('INBOX')]) + + // Identical pins;

The cached path already stripped all three; the split now lives in one helper so the two cannot drift again. Pi withheld literal values for every tool whenever ANY input in the whole run resolved a secret, which is true of almost any real workflow — the feature was effectively off there. It now asks the registry the same per-input-path question the Agent block asks, so only the tool that actually carries a secret is withheld.

Datadog's `listMonitorName` feeds the tool param `name`; it is now stated as Filter by Name "CPU" instead of dropped. `evaluateSubBlockCondition` answers the real question directly and survives a rename, because it never looks at tool param names. It also still excludes the stale-field case the name match was introduced for: Gmail's to/subject/body are gated to the send operations, so a block switched to Read drops them. The operation selector and trigger-mode subblocks are excluded explicitly — they carry values but do not constrain the call. Trigger mode is skipped per subblock rather than blocking its canonical group. Gmail puts `triggerCredentials` in the same group as `credential`, and blocking the group dropped the account from every Gmail tool. Only value-level disqualifiers — password, hidden, unstateable type — block a whole group, since a canonical group shares one value. --- apps/sim/providers/tool-binding.test.ts | 97 +++++++++++++++++++++++-- apps/sim/providers/tool-binding.ts | 43 ++++++++--- apps/sim/providers/utils.ts | 6 ++ 3 files changed, 131 insertions(+), 15 deletions(-) diff --git a/apps/sim/providers/tool-binding.test.ts b/apps/sim/providers/tool-binding.test.ts index 483f70da71e..aaa8d806b96 100644 --- a/apps/sim/providers/tool-binding.test.ts +++ b/apps/sim/providers/tool-binding.test.ts @@ -29,6 +29,7 @@ const collect = (over: Partial) => subBlocks: [], userProvidedParams: {}, resolvedResourceParams: {}, + conditionValues: {}, ...sourceOptions, ...over, } as CollectInput) @@ -127,18 +128,101 @@ describe('collectToolPinnedFields', () => { it('omits a field left over from a different operation on the same block', () => { const fields = collect({ subBlocks: [ - sub({ id: 'folder', title: 'Label', type: 'folder-selector' }), - sub({ id: 'to', title: 'To', type: 'short-input' }), - sub({ id: 'body', title: 'Body', type: 'long-input' }), + sub({ + id: 'folder', + title: 'Label', + type: 'folder-selector', + condition: { field: 'operation', value: 'read_gmail' }, + }), + sub({ + id: 'to', + title: 'To', + type: 'short-input', + condition: { field: 'operation', value: ['send_gmail', 'draft_gmail'] }, + }), + sub({ + id: 'body', + title: 'Body', + type: 'long-input', + condition: { field: 'operation', value: ['send_gmail', 'draft_gmail'] }, + }), ], // A block switched from Send to Read keeps the send fields in its params. userProvidedParams: { folder: 'INBOX', to: 'someone@example.com', body: 'stale draft' }, - toolParams: toolParams('folder', 'unreadOnly', 'maxResults'), + toolParams: toolParams('folder'), + conditionValues: { operation: 'read_gmail', folder: 'INBOX' }, }) expect(fields).toEqual([{ title: 'Label', value: 'INBOX' }]) }) + it('states a field the block renames on its way to the tool', () => { + // Datadog's `listMonitorName` subblock feeds the tool param `name`.
