skills that compound
The skills write themselves.
Start with 13 open-source skills, then let your team’s library grow itself. ZeroShot watches how your team actually works, identifies the patterns you keep repeating, builds new skills tuned to you — and makes sure they actually get used.
every monday. skills are files in a PR — review them like anything else your team ships.
[1] · the loop
Find, build, and use skills — automatically.
No blank page, no prompt library in a Notion doc nobody opens. Install the CLI and the loop starts running — you start with ours, we learn yours, the library compounds.
Install the CLI and ship with 13 open-source skills — a full spec-to-verify workflow, day one.
ZeroShot watches every session and PR review, spotting the work your team keeps repeating.
Those patterns become new skills — and sharpen the ones you have. Your library compounds; tokens drop.
[2] · proprietary signal extraction
We audit every session.
50+ signals, automatically.
ZeroShot reads every Claude Code, Codex, and Cursor session — across you and your whole team, single-player or multiplayer — and runs the proprietary BuildBetter signal pipeline over it. 50+ signal types surface the issues, blockers, repeated patterns, and inefficiencies hiding in how your team actually codes.
Retry loops, tool failures, and missing context — the moments your agents get stuck.
The same steering and corrections, over and over, across the whole team.
Token-heavy flows and re-derived context that quietly burn your budget.
The “actually, we do it this way” your reviews keep repeating.
[3] · skills that learn
Your junior inherits
your senior’s wins.
Every PR review your team writes, every steering correction, every “actually, we do it this way” becomes a skill the next person uses. The agent shows up already knowing the conventions your seniors settled on — so nobody spends tokens learning them the hard way again.
- →Conventions encoded once, applied by every agent
- →Skills update from your real review patterns, not a template
- →Draft reviews with /bb-review — suggestions cite prior conventions, cutting PR review time by 67%
- →We open a weekly PR suggesting new skills from your sessions
[4] · highest-roi skills
We build the highest-ROI skills —
and prove it on your history.
ZeroShot ranks every skill opportunity by impact, builds it, and backtests it against your existing sessions — so you see exactly which skills speed up development the most, and save the most, before you ship them. Estimates, not vibes.
└ Your team re-flagged the same 3 conventions across 11 PRs.
└ 4 agents rebuilt the same dashboard 3× before settling on a layout.
└ Cross-machine context re-derivation showed up in 6 sessions. · applied
note ─ we open a PR every Monday with new skills from last week’s sessions. estimated savings — your mileage will vary.
+ Found for your team — skills ZeroShot wrote by watching how you work
└ every skill is a file — review it, edit it, delete it. nothing is a black box.
[5] · enforcement & adoption
A skill no one uses is worthless.
You can have a million skill files — if no one runs them, nothing changes. ZeroShot lets you dictate when each skill fires, and tracks coverage so adoption actually happens.
- →Run skills automatically on a flow, or leave them manual — you decide
- →Require a skill before a PR goes up for review
- →Coverage tracking shows who’s actually using each skill — and who isn’t
why this exists
"One of my engineers spent $40,000 on tokens last month, and I genuinely don’t know whether I should stop him."
— Vitaly Gordon, CEO, Faros AI · via TechCrunch →
ZeroShot flagged that my Playwright skill was burning about $4k a month. It rebuilt the skill around it — now it's about $200 a month and 10× faster.
— Spencer Shulem, CEO
