What is template-discovery?

A tool for finding and inspecting `.NET` project templates, which are starting blueprints for applications and services created with `dotnet new`. It matches a project description to available templates and their settings.

Use it to search templates, compare possible matches at a high level, and inspect their parameters and constraints.

It helps you choose a suitable starting point and understand what a template creates before committing to it.

Token cost

What it costs to keep this loaded

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	$0.00158	$0.02932
Opus 5	$0.00079	$0.01466
Sonnet 5	$0.00032	$0.00586
Haiku 4.5	$0.00016	$0.00293

Security

Grade A, and why

template-discovery 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 today.

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.

How it starts

The opening of the file, as written. The whole thing — 216 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Template Discovery

This skill helps an agent find, inspect, and select the right dotnet new template for a given task using dotnet new CLI commands for search, listing, and parameter inspection.

When to Use

User asks "What templates are available for X?"
User describes a project in natural language ("I need a web API with authentication")
User wants to compare templates or understand parameters before creating a project
User needs to know what a template produces (files, structure) before committing

When Not to Use

User wants to create a project — route to template-instantiation skill
User wants to author or validate a custom template — route to template-authoring skill
User wants a detailed side-by-side comparison of templates — route to template-comparison skill
User wants smart cross-parameter defaults during creation — route to template-smart-defaults skill
User is troubleshooting build issues — route to dotnet-msbuild plugin

Recommendation requests: answer first, confirm second. Inspection requests: inspect first. For a general "which template?" question, start from the Step 1 mappings so a transient CLI failure cannot leave the user without an answer. When the user explicitly asks what is installed, requests exact options/defaults, or asks for dry-run output, run the relevant dotnet new command before writing the final answer. Never end a turn on a dotnet new call or a "let me confirm..." teaser.

Inspection requests require inspection. If the user asks for installed choices, exact parameters/defaults, compatibility constraints, or the exact dry-run file list, run the corresponding dotnet new command. Do not replace observed data with remembered flags. Report a flag only when the current template's --help output contains it.

Inputs

Input	Required	Description
User intent or keywords	Yes	Natural-language description or keywords (e.g., "web API", "console app", "MAUI")
Language preference	No	C#, F#, or VB — defaults to C#
Framework preference	No	Target framework (e.g., net10.0, net9.0)

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.
