Greptile Overview

Greptile Summary

• Aggregates recent changes across Slack trigger, Linear tools/pagination, executor edge scheduling, and resolver metrics formatting into a single release PR.
• Adds Slack webhook trigger support for file attachments and related webhook execution/utilities wiring.
• Refactors/aligns Linear tool schemas and pagination behavior to match the upstream API and updates docs accordingly.
• Fixes executor edge-manager logic around sentinel-end handling, with associated unit test updates.

Confidence Score: 3/5

• This PR is mergeable after fixing a few workflow-breaking behavioral changes in schema generation and Slack webhook normalization.
• Most changes are straightforward refactors or well-scoped fixes (executor sentinel-end gating, Linear pagination alignment) with added test coverage. However, there are a couple of definite regressions: responseFormat schema currently drops base outputs (breaking downstream references) and Slack webhook formatting now normalizes non-event_callback payloads (can trigger workflows on url_verification/other types). There is also a credential visibility mismatch for user-supplied Slack bot tokens.
• apps/sim/executor/utils/block-data.ts; apps/sim/lib/webhooks/utils.server.ts; apps/sim/triggers/slack/webhook.ts

Important Files Changed

Filename	Overview
apps/docs/content/docs/en/tools/linear.mdx	Updates Linear tool documentation, likely covering new pagination behavior and output fields; no code execution impact observed.
apps/sim/background/webhook-execution.ts	Extends webhook attachment processing for nested object schemas and adds trigger inference fallback; needs attention due to broadened trigger resolution paths.
apps/sim/blocks/blocks/linear.ts	Expands and consolidates pagination parameter exposure across many Linear operations; large conditional logic change but appears consistent.
apps/sim/executor/execution/edge-manager.ts	Fixes sentinel-end queuing by gating readiness checks on activatedTargets; addresses deactivated-branch execution bug.
apps/sim/executor/utils/block-data.ts	Adds evaluator/responseFormat-derived output schemas; responseFormat path currently drops base outputs from schema (breaks downstream references).
apps/sim/lib/webhooks/utils.server.ts	Adds Slack file download support and changes Slack payload normalization; now formats non-event_callback Slack payloads (may trigger workflows on url_verification).
apps/sim/tools/linear/types.ts	Introduces shared Linear output property constants and pageInfo schema used across tools; large refactor but type-only changes.
apps/sim/triggers/slack/webhook.ts	Adds bot token + includeFiles options and exposes files/hasFiles outputs; botToken is marked hidden (credential visibility inconsistency).

apps/sim/lib/webhooks/utils.server.ts
Slack events now always formatted

This removes the body.type === 'event_callback' gate and will return a normalized event object even for non-event_callback Slack payloads (e.g. url_verification). In those cases rawEvent is typically missing and this code logs a warning but still returns an event with mostly empty fields and event_type derived from body.type. That’s a behavior change that can cause workflows to run on Slack verification requests with empty text/channel/user.

If only event_callback should trigger workflows, the early return should remain (or explicitly return undefined/error for other Slack types).
