¿Puedo vibecodear Debriefing?
PARCIAL · un fin de semanaDiffing a competitor's pricing page on a cron and asking a model what changed is genuinely an afternoon. changedetection.io will do the watching for you before you write a line. The gap is everything between a diff and a brief. Most page changes are noise: a rotated testimonial, a reordered nav, a CDN hash. Deciding which changes are real, tying them to hiring and funding signals, and turning that into three sentences a founder acts on is judgement encoded over many iterations. Build it and your first month is mostly you deleting alerts about nothing.
Build me a local competitor watch that emails me a weekly brief, to replace Debriefing. Requirements: - Node 22, TypeScript, SQLite via better-sqlite3, Playwright for fetching, node-cron for the schedule. CLI only. No accounts, no telemetry, keys in .env. - competitors.json lists each rival: name, and the URLs that matter (homepage, pricing, changelog, careers). Ship it seeded with 3 competitors and 4 URLs each. - `watch snapshot` fetches every URL with Playwright, strips scripts, styles, nav and footer, converts the main content to plain text, and stores it with a SHA-256 hash and a timestamp. Skip storage entirely when the hash is unchanged. - Diff each new snapshot against the previous one as unified text diff. Discard diffs under 40 changed characters, and drop lines matching an editable noise.json of regexes (dates, cache-busting hashes, view counts, testimonial rotations). - `watch brief` sends the surviving diffs for the period to Claude or GPT in one call and asks for, per competitor: what changed, why it matters, and one suggested response. Require a citation back to the exact URL for every claim, and drop any bullet without one. - Render the brief to Markdown in ~/CompetitorBriefs/YYYY-MM-DD.md and send it via SMTP from .env. The file is the source of truth, email is just delivery. - Keep every snapshot and every brief. `watch history <competitor>` prints that rival's changes over time, which is the only way a single diff becomes a trend. - Out of scope: hiring feeds, funding data, traffic estimates, dashboards and any login wall. Public pages only, respect robots.txt, one request per URL per run. - README: setup, a cron line for the weekly run, the per-brief token cost, and a warning that month one is mostly tuning noise.json.

Because a diff is not intelligence. The hard part is not fetching a pricing page every week, it is knowing that this particular change matters and the other eleven do not, then saying so in three sentences a founder can act on before a Monday call. That judgement lives in accumulated history and a lot of tuning against false positives. It also survives being ignored: a brief that arrives whether or not you remembered to look is worth more than a script you stop reading in week three.
