Getting it into your agent
There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

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 | $0.00210 | $0.01995 |
| Opus 5 | $0.00105 | $0.00997 |
| Sonnet 5 | $0.00042 | $0.00399 |
| Haiku 4.5 | $0.00021 | $0.00199 |
Grade C, and why
aspire-init scanned grade C with 2 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 6d 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.

Aspire Init
First-run only. This skill owns the skeleton drop and template choice for repositories that do not yet have an Aspire AppHost. Once the skeleton is in place, hand off to
aspireifyfor the actual resource wiring.
Prerequisites
| Requirement | Install |
|---|---|
| .NET 10.0 SDK | https://dotnet.microsoft.com/download |
| Aspire CLI (curl installer) | curl -sSL https://aspire.dev/install.sh | bash |
| Aspire CLI (NativeAOT global tool) | dotnet tool install -g Aspire.Cli (.NET 10 required) |
| Diagnose missing prerequisites | aspire doctor |
Aspire ships the CLI as a NativeAOT .NET global tool — instant startup, no JIT warmup. The curl/PowerShell installer remains supported for environments without .NET 10.
Detection
Activate only when adding Aspire to a workspace that does not yet have one. Confirm ALL
of the following before running aspire init:
| Signal | How to Detect | Meaning |
|---|---|---|
| No C# AppHost | No .csproj containing Aspire.AppHost.Sdk |
OK to init |
| No file-based AppHost | No apphost.cs with #:sdk Aspire.AppHost.Sdk |
OK to init |
| No TypeScript AppHost | No apphost.ts in repo root |
OK to init |
| No Aspire config | No aspire.config.json in repo root |
OK to init |
| User intent | Explicit "add Aspire", "scaffold Aspire", "aspire init" | OK to init |
If any AppHost signal is already present, do not run aspire init. Route to
aspireify (re-wire) or
aspire-orchestration (lifecycle).
Decision: aspire new vs aspire init
| Situation | Command | Why |
|---|---|---|
| Empty directory or brand-new project | aspire new <template> |
Generates a full starter solution |
| Existing repo with services to model | aspire init |
Drops minimal skeleton + aspire.config.json next to existing code |
| User wants a sample to learn from | aspire new aspire-starter |
Includes ApiService + Web + ServiceDefaults |
| User wants the smallest possible scaffold | aspire new aspire-empty (C#) or aspire new aspire-ts-empty (TS) |
No resources pre-wired |
| User wants Python services | aspire new aspire-py-starter (TypeScript AppHost drives Python) |
Not dotnet new — that template was removed in 13.3 |
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

aspire-init is a skill published in the GitHub repository thangchung/agent-engineering-experiment (24 stars, last pushed 1mo ago), licensed MIT. It adds 210 tokens to every session and 1,995 once invoked, about $0.0011 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
