Better-T-Stack is a command-line tool that generates end-to-end, type-safe TypeScript project scaffolds from selectable frontend, backend, database, authentication, and tooling options. Developers use it to start full-stack applications with a stack tailored to their needs. The catalogue includes skills, agents, commands, an MCP server, and a plugin for having coding agents plan and generate Better-T-Stack projects.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00084 | $0.00533 |
| Opus 5 | $0.00042 | $0.00267 |
| Sonnet 5 | $0.00017 | $0.00107 |
| Haiku 4.5 | $0.00008 | $0.00053 |
Grade A, and why
add-to-project scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Add addons to an existing Better-T-Stack project
Use the Better-T-Stack MCP server to install addons into an existing project rather than wiring the tooling by hand.
When this applies
The user already has a Better-T-Stack project (look for a bts.jsonc config) and wants to add tooling or features — e.g. "add PWA support", "add a docs site", "switch to Biome", "add Turborepo", "wire up the MCP addon".
For brand-new projects, use the scaffold-project skill instead.
Workflow
- Confirm the target project is a Better-T-Stack project and identify its directory.
- Plan. Call
bts_plan_addonswith the desired addon set (and any nestedaddonOptions). This is a dry run — review the planned changes with the user. - Apply. Only after the plan succeeds and matches intent, call
bts_add_addons. - Report what changed and the follow-up commands to run.
Available addons
pwa, tauri, electrobun, starlight, biome, lefthook, husky, mcp, turborepo, nx, vite-plus, fumadocs, ultracite, oxlint, opentui, wxt, skills, evlog.
Note: nx, turborepo, and vite-plus are mutually exclusive task runners. Use bts_get_schema for nested addon options (e.g. Fumadocs templates/search/AI chat, WXT templates, OpenTUI templates).
Rules
- Always
bts_plan_addonsbeforebts_add_addons. - Don't add addons the user didn't ask for.
- Surface any conflicts (e.g. two task runners) from the plan before applying.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

add-to-project is a skill published in the GitHub repository AmanVarshney01/create-better-t-stack (5,697 stars, last pushed 4d ago), licensed MIT. It adds 84 tokens to every session and 533 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
