In plain words
What is it for?
It is for starting and stopping Aspire apps, inspecting resources, waiting for services to become healthy, reading logs and traces, adding integrations, and updating AppHost packages.
Why use it?
It gathers common Aspire commands for starting applications, checking resources, viewing logs and traces, and diagnosing problems.

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is starling-browser/starling's own configuration. It tells Claude Code and Codex how to work on starling itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything starling configures →

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.

Security

Grade A, and why

aspire 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.

Aspire Skill

This repository uses Aspire to orchestrate its distributed application. Resources are defined in the AppHost project (apphost.cs or apphost.ts).

CLI command reference

Task Command
Start the app aspire start
Start isolated (worktrees) aspire start --isolated
Restart the app aspire start (stops previous automatically)
Wait for resource healthy aspire wait <resource>
Stop the app aspire stop
List resources aspire describe or aspire resources
Run resource command aspire resource <resource> <command>
Start/stop/restart resource `aspire resource start
Rebuild a .NET project resource aspire resource <resource> rebuild
View console logs aspire logs [resource]
View structured logs aspire otel logs [resource]
View traces aspire otel traces [resource]
Logs for a trace aspire otel logs --trace-id <id>
Add an integration aspire add
List running AppHosts aspire ps
Update AppHost packages aspire update
Search docs aspire docs search <query>
Get doc page aspire docs get <slug>
List doc pages aspire docs list
Environment diagnostics aspire doctor
List resource MCP tools aspire mcp tools
Call resource MCP tool aspire mcp call <resource> <tool> --input <json>

Most commands support --format Json for machine-readable output. Use --apphost <path> to target a specific AppHost.

Key workflows

Running in agent environments

Use aspire start to run the AppHost in the background. When working in a git worktree, use --isolated to avoid port conflicts and to prevent sharing user secrets or other local state with other running instances:

aspire start --isolated

Use aspire wait <resource> to block until a resource is healthy before interacting with it:

aspire start --isolated
aspire wait myapi

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.
