Commercial Agent Tools: October 21, 2026

1. Seclai Bundles Agent Tracing, Plain-English Governance and Evals in One Runtime

Seclai. Seclai, posted to Show HN on October 20, is a hosted platform for running LLM agents in production that combines workflow orchestration, step-level traces with replay, evals and governance. Governance policies are written in plain English, and every input and output is graded against flag and block thresholds for areas such as content safety, PII and forbidden topics. Eval sets run with the same semantics locally, in CI and in production, and users can switch among more than 200 models. Pricing is credit-based: Personal at $15 per month, Starter at $25 (14-day trial), Team at $75 and Pro at $375, with top-ups at $10 per 100,000 credits. Source

2. Skillsync Searches Every Past Coding Agent Session on Each Prompt

Skillsync. Skillsync, a Y Combinator-backed Mac app shown on Show HN on October 20, installs plugins for coding agents including Claude Code, Codex, Cursor, OpenCode, Amp and Pi. On every prompt it runs decision models that decide whether past work is relevant, search all prior sessions without any pre-indexing, and attach a short recollection with sources to the prompt. A global hotkey also opens a search over all sessions. Pricing: an open-source CLI (txcript) for MCP session search and session transfer is free, Pro with instant recall, shared workspaces and a skill library costs $20 per seat per month with a 5-day trial, and Team pricing is custom.

3. Doozy Puts a Task-Running Agent Into Slack Threads

Doozy. Doozy, posted to Show HN on October 20, is an agent that teammates assign work to in Slack threads; it carries out the task in connected tools such as Stripe and Intercom and posts the result, such as a spreadsheet, back to the thread with a receipt of every step. The launch pitches it at support, operations and founders and says it works in production systems without users handing over their keys, and that it can be set up without an engineer. Pricing: a 14-day free trial with no card required; paid plan details are on the product site. Source

4. BonBook Launches an MCP Connector for Searching and Booking Flights in Claude

BonBook. Travel booking service BonBook, which began as flight booking by email, released an MCP connector on October 20 that lets Claude users search live flights and book them in about 35 seconds, according to the company, while keeping loyalty points and status. Setup is adding a custom connector URL in Claude’s settings with no BonBook account or password; the first booking opens a bonbook.co checkout page, and later bookings can be confirmed in chat. Custom connectors require a paid Claude plan; BonBook does not list its own fees on the setup page. Source
