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 | $0.00082 | $0.00703 |
| Opus 5 | $0.00041 | $0.00351 |
| Sonnet 5 | $0.00016 | $0.00141 |
| Haiku 4.5 | $0.00008 | $0.00070 |
Grade A, and why
spring-boot-create 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 8d 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.

Create a New Spring Boot Project
Use arconia create to scaffold a new Spring Boot project from a template.
Templates are pre-configured project structures distributed as OCI artifacts.
Create a project
arconia create --name my-app --template server-http
Both --name and --template are required.
Common options
| Option | Default | Description |
|---|---|---|
--name |
(required) | Project name (used as directory name and artifact ID) |
--template |
(required) | Template alias or full OCI reference |
--group |
com.example |
Group ID (e.g., io.arconia) |
--description |
Project description | |
--package-name |
Java package name (defaults from group + name) | |
--path |
current directory | Where to create the project |
Example with all options
arconia create \
--name my-app \
--template server-http \
--group io.arconia \
--description "My web application" \
--package-name io.arconia.app
Discover available templates
List all templates from registered catalogs:
arconia template list
List templates from a specific catalog:
arconia template list --name arconia-project-templates
Template references
Templates can be specified as:
- Alias (short name):
server-http— resolved from a registered template catalog - Full OCI reference:
ghcr.io/arconia-io/arconia-templates/server-http— fetched directly
Use aliases when available (shorter, easier to remember). Use full OCI references when the template is not in a registered catalog.
Workflow
- Discover templates:
arconia template list - Pick a template that matches the project requirements
- Create the project:
arconia create --name my-app --template <template> - Navigate into the project:
cd my-app - Start developing:
arconia dev
Gotchas
- Template aliases only work if a catalog containing them is registered. If an alias is not found, use the full OCI reference instead.
- The
--groupdefaults tocom.example. Set it to the actual organization group ID (e.g.,io.arconia) for real projects. - The project is created in a subdirectory named after
--nameinside the--pathdirectory (defaults to the current directory).
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.

spring-boot-create is a skill published in the GitHub repository arconia-io/agent-skills (2 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 82 tokens to every session and 703 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 2026-08-31.
