# Build Kit: Find What You Already Have Before You Build > The Build Kit is a software reuse analysis in the Ai1 platform by MyZone AI: it breaks a technical plan into its smallest pieces, checks each one against what is already on your Ai1 server and sorts it into have it, reuse after a refresh or build new, so your team only builds what is really new.

Reviewed by the MyZone AI team. Find what you already have before you build, so you only build what is new. ## At a glance - **Starts from:** A drafted technical plan, before the estimate is agreed - **Checks against:** The skills, scripts, agents, shared components and apps on your Ai1 server - **Sorts each piece:** Have it, reuse after a refresh or build new - **Every gap:** Lists where it searched, so a gap is a real gap - **Before the build uses it:** A person on your team reviews and accepts the report - **What it never does:** Build anything, set prices or hours, or send anything to your customers ## What the Build Kit does - **Breaks the plan into pieces:** It splits a technical plan into the smallest parts that could be reused or built, so nothing hides inside a big line item. - **Checks what is already there:** Each piece is matched against the skills, scripts, agents, shared components and apps on your Ai1 server. - **Writes the Build Kit report:** Piece by piece, the report shows what you have as it is, what can be reused after a refresh and what needs building, with the best starting point noted. - **Shows its search for every gap:** When something is missing, the report lists where it searched, so you can trust the answer. - **Checks claims in the plan:** If the plan says to reuse something, it confirms that thing really exists and flags it to the project lead when it does not. - **Flags pieces worth sharing:** Pieces other projects could use too are flagged and passed to the owners who decide on shared components. ## How the Build Kit differs from a quick code search A quick search tells you whether something with a similar name exists. The Build Kit will break your whole technical plan into its smallest pieces, check each one against your Ai1 server and sort it into have it, reuse after a refresh or build new. Every gap lists where it searched, and claims in the plan are checked too. Each report stays tied to its plan version, and a person accepts it before the build uses it. ## How it works 1. **Plan is drafted** (Before the estimate): Your project lead or development agent asks for a run once the technical plan exists and before the estimate is agreed. 2. **Break it down** (Right after the request): Build Kit splits the plan into its smallest pieces. 3. **Match against your server** (Piece by piece): Each piece is checked against what is already on your Ai1 server and sorted into have it, reuse it or build it. 4. **A person reviews the report** (you approve) (Before the build uses it): The report stays a draft until a person on your team reviews and accepts it. Only then does the build use it. 5. **Report and route** (Once accepted): The accepted report goes to your development team, and gaps and shareable pieces go to their owners. ## When to use it - **A new client portal has a technical plan but no estimate yet:** The report lists every piece and whether you have it, can reuse it or need to build it, before the estimate is agreed. - **The plan changed after the last run:** The old report is marked out of date and a fresh run matches the new version. - **You wonder whether something similar was built before:** It searches your server and says what it found and where it looked. - **A new agent is being planned:** It breaks the agent's plan into pieces and shows which ones can be reused. ## What you get - A Build Kit report sorting every piece into have it, reuse after a refresh or build new - The search behind every gap, listed in full - A check of what the plan claims already exists - A list of pieces worth sharing with other projects ## Example: Build Kit report Example with a fictional company. Names, people and figures are invented to show the agent's output. Any resemblance to a real company or person is unintended. What it was asked: Run the Build Kit on our approved client portal plan so we know what we already have, what needs a refresh and what really has to be built before we agree the estimate. Build Kit took the approved technical plan (version 1.2, tied to the report by its fingerprint), split it into 18 pieces and matched each one against a snapshot of the server's inventory; every missing piece lists what was searched. In a real run the report stays a draft until an independent inventory cross-check and the project lead's acceptance, and it only reads: it builds nothing, sets no prices or hours, and people decide what to build. This example uses an invented company, invented install names and invented counts, and is trimmed (per-row search logs and the machine-readable files are left out). Run date: 30 September 2026. ### What it found - 12 of the 18 pieces in the client portal plan already exist on the company's server: 7 can be used as they are and 5 need a stated refresh, such as a 30-day share link. - Three pieces are real gaps worth building once for every project (a service-area check, a report viewer and online signing), and three are this company's own rules, like its price-by-home-size formula. - The plan says to reuse an e-signing tool from the quoting app, but no such tool exists anywhere on the server; the report lists every place it searched and flags it to the project lead. ## Guardrails - A person reviews and accepts each report before the build uses it. - It only reads. It builds nothing and sets no prices or hours. People decide what to build. - It is an internal planning report for your development team and is never sent to your customers. - It names things by their installed name only and never shows passwords, keys or other customers' names. ## Frequently asked questions ### How do I find existing code I can reuse before a new build? Check each piece of the plan against what you already have before the estimate is agreed. The Build Kit in Ai1 by MyZone AI matches every piece against the skills, scripts, agents, shared components and apps on your Ai1 server, and says where it looked for anything missing. It does not run automatically when a plan is written. Your project lead or development agent asks for it once the plan is drafted and before the estimate is agreed. ### How do you decide whether to build or reuse a software piece? Start from evidence: does the piece exist as it is, can it be reused after a refresh, or is it really missing? The Build Kit report sorts every piece that way, with the best starting point noted. People on your team decide what to build. For every piece of your plan, the reuse analysis shows whether you already have it, can reuse it after a refresh or need to build it, with the search behind each gap. ### What is a software component inventory? It is a record of the pieces you already have, such as skills, scripts, agents, shared components and apps. The Build Kit will check a plan against what is on your Ai1 server, while keeping the inventory of registered pieces stays with your Ai1 team. The Build Kit report is an internal planning report for your development team. It never sends anything to a client. ### Is Build Kit available today, and does it build the missing pieces? Yes. Build Kit is ready to use in Ai1 by MyZone AI. It does not build anything. It writes the report, and your project lead and development agents decide what to build and build it. ## More on this topic - [Multi-Agent Development: Why the Future of Software Is Built by AI Teams](https://myzone.ai/pages/blog/multi-agent-development): Discover how multi-agent AI systems are transforming software development.
