Problem Statement

๐— ๐—ถ๐˜…๐—ฒ๐—ฑ-๐—ฝ๐—ฟ๐—ถ๐—ผ๐—ฟ๐—ถ๐˜๐˜† ๐—ถ๐—ป๐—ฏ๐—ผ๐˜…: Job opportunities, interview confirmations, newsletters, and general messages all arrived in the same feed with no built-in way to tell urgent items from noise.

๐—œ๐—ป๐—ฐ๐—ผ๐—ป๐˜€๐—ถ๐˜€๐˜๐—ฒ๐—ป๐˜ ๐—บ๐—ฎ๐—ป๐˜‚๐—ฎ๐—น ๐˜๐—ฟ๐—ถ๐—ฎ๐—ด๐—ฒ: Deciding whether a job posting was actually a good match required reading full postings every time, a judgment call that is slow and inconsistent when done manually.

๐——๐—ฒ๐—น๐—ฎ๐˜†๐—ฒ๐—ฑ ๐—ฟ๐—ฒ๐˜€๐—ฝ๐—ผ๐—ป๐˜€๐—ฒ ๐˜๐—ผ ๐˜๐—ถ๐—บ๐—ฒ-๐˜€๐—ฒ๐—ป๐˜€๐—ถ๐˜๐—ถ๐˜ƒ๐—ฒ ๐—ถ๐˜๐—ฒ๐—บ๐˜€: Interview scheduling emails and strong job matches often need same-day attention, but manual inbox checking introduces unpredictable delays.

๐—ก๐—ฒ๐˜„๐˜€๐—น๐—ฒ๐˜๐˜๐—ฒ๐—ฟ ๐—ผ๐˜ƒ๐—ฒ๐—ฟ๐—น๐—ผ๐—ฎ๐—ฑ: Subscriptions and recurring senders clutter the inbox, and most contain nothing worth acting on, but skimming all of them still costs time daily.

๐—ก๐—ผ ๐˜€๐˜๐—ฟ๐˜‚๐—ฐ๐˜๐˜‚๐—ฟ๐—ฒ๐—ฑ ๐—ฟ๐—ฒ๐—ฐ๐—ผ๐—ฟ๐—ฑ-๐—ธ๐—ฒ๐—ฒ๐—ฝ๐—ถ๐—ป๐—ด: Job leads, matches, and newsletter content had no consistent home for tracking, meaning good opportunities could get lost after the first read.

Solution Design

The agent was built around a single Gmail trigger, with AI judgment layered in at every point where a real decision needed to be made rather than a fixed rule.

๐—ง๐—ฟ๐—ถ๐—ด๐—ด๐—ฒ๐—ฟ: A Gmail node fires on every new incoming email, starting the workflow in real time as messages arrive.

๐——๐—ฎ๐˜๐—ฎ ๐—ฒ๐˜…๐˜๐—ฟ๐—ฎ๐—ฐ๐˜๐—ถ๐—ผ๐—ป (๐—ณ๐—ถ๐˜…๐—ฒ๐—ฑ ๐—น๐—ผ๐—ด๐—ถ๐—ฐ): An Extract Email Data step parses the raw email into structured fields the rest of the workflow can use.

๐—”๐—œ ๐—ฐ๐—ฎ๐˜๐—ฒ๐—ด๐—ผ๐—ฟ๐˜† ๐—ฐ๐—น๐—ฎ๐˜€๐˜€๐—ถ๐—ณ๐—ถ๐—ฐ๐—ฎ๐˜๐—ถ๐—ผ๐—ป: A "DM: Category Allocator" AI node, equipped with its own tool access, reads the email content and classifies it into a category such as job posting, interview scheduling, generic message, or newsletter. This is a genuine AI judgment call, not a keyword match.

๐—™๐—ถ๐˜…๐—ฒ๐—ฑ ๐—ฟ๐˜‚๐—น๐—ฒ-๐—ฏ๐—ฎ๐˜€๐—ฒ๐—ฑ ๐—ฟ๐—ผ๐˜‚๐˜๐—ถ๐—ป๐—ด: A JSON formatting step feeds a Route By Category router running in strict rules mode, which sends the email down one of four paths purely based on the AI's classification output.

๐—๐—ผ๐—ฏ ๐—ฝ๐—ผ๐˜€๐˜๐—ถ๐—ป๐—ด ๐—ฝ๐—ฎ๐˜๐—ต (๐—”๐—œ ๐˜€๐—ฐ๐—ผ๐—ฟ๐—ถ๐—ป๐—ด): For job-related emails, the agent fetches the full job page, extracts the job description, and combines it with candidate context before a "DM: Job Matching" AI node, also with tool access, scores how well the role matches the user's profile.

๐—™๐—ถ๐˜…๐—ฒ๐—ฑ ๐˜๐—ต๐—ฟ๐—ฒ๐˜€๐—ต๐—ผ๐—น๐—ฑ ๐—ฑ๐—ฒ๐—ฐ๐—ถ๐˜€๐—ถ๐—ผ๐—ป: An Extract Score step pulls the numeric score, and a fixed rule checks whether it clears a match threshold, splitting into a high-match and low-match path.

๐—œ๐—ป๐˜๐—ฒ๐—ฟ๐˜ƒ๐—ถ๐—ฒ๐˜„ ๐˜€๐—ฐ๐—ต๐—ฒ๐—ฑ๐˜‚๐—น๐—ถ๐—ป๐—ด ๐—ฝ๐—ฎ๐˜๐—ต (๐—”๐—œ ๐—ถ๐—ป๐˜๐—ฒ๐—ฟ๐—ฝ๐—ฟ๐—ฒ๐˜๐—ฎ๐˜๐—ถ๐—ผ๐—ป): A "DM: Interview Scheduled" AI node reads interview-related emails and generates a real-time WhatsApp notification summarizing key details.

๐—š๐—ฒ๐—ป๐—ฒ๐—ฟ๐—ถ๐—ฐ ๐—ฎ๐—ป๐—ฑ ๐—ป๐—ฒ๐˜„๐˜€๐—น๐—ฒ๐˜๐˜๐—ฒ๐—ฟ ๐—ฝ๐—ฎ๐˜๐—ต๐˜€ (๐—”๐—œ ๐˜€๐˜‚๐—บ๐—บ๐—ฎ๐—ฟ๐—ถ๐˜‡๐—ฎ๐˜๐—ถ๐—ผ๐—ป ๐—ฎ๐—ป๐—ฑ ๐—ณ๐—ถ๐—น๐˜๐—ฒ๐—ฟ๐—ถ๐—ป๐—ด): A "DM: Generic" AI node handles miscellaneous messages, while a separate skip-list check and a "DM: Important News" AI node filter newsletters, deciding which ones are worth logging as a digest versus silently skipped.

๐—ฆ๐˜๐—ฟ๐˜‚๐—ฐ๐˜๐˜‚๐—ฟ๐—ฒ๐—ฑ ๐—น๐—ผ๐—ด๐—ด๐—ถ๐—ป๐—ด ๐—ฎ๐—ป๐—ฑ ๐—ฎ๐—น๐—ฒ๐—ฟ๐˜๐—ถ๐—ป๐—ด (๐—บ๐—ถ๐˜…๐—ฒ๐—ฑ ๐—”๐—œ ๐—ฎ๐—ป๐—ฑ ๐—ณ๐—ถ๐˜…๐—ฒ๐—ฑ ๐—น๐—ผ๐—ด๐—ถ๐—ฐ): Every branch ends in either a Supabase insert for structured record-keeping or a WhatsApp notification for anything requiring immediate human attention.
