Skills that compound

Find, build, and use
more skills — automatically.

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.

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
  • We open a weekly PR suggesting new skills from your sessions

Each correction your team makes once is in the skill the next person uses.
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.

Issues & blockers

Retry loops, tool failures, and missing context — the moments your agents get stuck.

Repeated patterns

The same steering and corrections, over and over, across the whole team.

Inefficiencies

Token-heavy flows and re-derived context that quietly burn your budget.

Conventions

The “actually, we do it this way” your reviews keep repeating.

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.

We open a PR every Monday with new skills based on last week’s sessions. Estimated savings — your mileage will vary.
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
