What is Knock?

Knock is building an agent-and-environments layer on top of its notifications infrastructure

Knock is shipping fast on two fronts: an agent surface (trigger Knock from Slack, package reusable agent skills, build audiences via agent) and developer-workflow primitives (reusable input schemas, dynamic audiences that version and promote between environments, new partial input types). The throughline is making notification engineering programmable and agent-operable.

What is Semgrep?

Semgrep grinds forward on language coverage and Pro taint-engine performance

Semgrep's recent releases are a steady stream of language-parser improvements (Dart typed metavariables, PHP 8.5, Scala 3.4 traits, Kotlin grammar) paired with sustained performance work on the Pro interfile taint engine and rule parsing, including 5x faster JSON rule loading in 1.162.0. Output and infra controls also got attention, like a configurable match-context cap for minified files.

Knock is building an agent-and-environments layer on top of its notifications infrastructure

◆ Current state

Knock is shipping fast on two fronts: an agent surface (trigger Knock from Slack, package reusable agent skills, build audiences via agent) and developer-workflow primitives (reusable input schemas, dynamic audiences that version and promote between environments, new partial input types). The throughline is making notification engineering programmable and agent-operable.

◆ Where it's heading

Knock is moving from a notifications API toward an agent-operable platform with environment-promotion workflows — audiences, layouts, and inputs all becoming versioned, previewable artifacts drivable from dashboard, CLI, or agent. Expect more agent-triggerable surface area.

◆ Prediction

Likely more agent-driven authoring (additional data sources, agent skills) and continued environment/versioning tooling; the Slack agent and CLI/agent build paths point to deeper automation of notification ops.

Semgrep grinds forward on language coverage and Pro taint-engine performance

◆ Current state

Semgrep's recent releases are a steady stream of language-parser improvements (Dart typed metavariables, PHP 8.5, Scala 3.4 traits, Kotlin grammar) paired with sustained performance work on the Pro interfile taint engine and rule parsing, including 5x faster JSON rule loading in 1.162.0. Output and infra controls also got attention, like a configurable match-context cap for minified files.

◆ Where it's heading

The direction is breadth (more languages parsed accurately) and depth (faster, more precise cross-file taint analysis in the Pro engine). The recent interfile taint redesign and parallelized taint-config computation point to scaling Pro scans on large codebases as the priority.

◆ Prediction

Expect continued per-language parser upgrades and further Pro taint-engine performance and precision work.
