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 | $0.00000 | $0.00646 |
| Opus 5.5 | $0.00000 | $0.00258 |
| Sonnet 5.5 | $0.00000 | $0.00129 |
| Haiku 4.5 | $0.00000 | $0.00065 |
Grade A, and why
spring-boot-cloud-config 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 14d 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.
How it starts
The opening of the file, as written. The whole thing — 61 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Spring Cloud Config Contract
Apply this contract when a module is a Spring Cloud Config Server or a Config client. Pom owns the Boot ↔ Cloud BOM train. Configuration owns profiles and secrets. TLS owns HTTPS keystores and trust. Security owns filter-chain style. Vault remains a separate secrets integration (Vault contract).
Shared dependency management
- Import
spring-cloud-dependenciesas a BOM; choose the train from the pom contract (Boot 4.1.x:2025.1.2or newer). Do not pin Config Server/client artifact versions outside the BOM.
Config Server
- Add
spring-cloud-config-serverand annotate the application with@EnableConfigServer. - Point
spring.cloud.config.server.git.uriat the configuration Git repo (local file URI or remote URL). Prefer an environment override for the path or URL, and setcloneOnStart: truewhen the server should clone before serving. - Use
search-paths: "{application}/{profile}"sospring.application.name+ active profile select the right folder under the Git backend. - Protect client-facing config HTTP paths with authentication; supply server and
client passwords from the environment (for example HTTP Basic with
CONFIG_SERVER_*/CLOUD_CONFIG_CLIENT_*). - Development may serve plain HTTP. When the server serves HTTPS, follow the TLS contract for keystore settings.
- Initialize the configuration Git backend before first run when using a fresh local repository (commit at least one application/profile tree).
Config client
- Add
spring-cloud-starter-config. - Set
spring.application.nameto the Git application folder name the server should serve. - Import Config Data with
spring.config.importpointing at the Config Server URL (for exampleoptional:configserver:http://localhost:8888in development and an HTTPS URL in production). - Supply
spring.cloud.config.username/passwordfrom the environment when the server requires auth; values must match the server. - Bind remote properties through
@ConfigurationPropertiesin the feature package. - Keep context tests independent of a live Config Server (for example
optional:configserver:import andspring.cloud.config.fail-fast=falsein tests).
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-cloud-config is a cursor rule published in the GitHub repository lsampaioweb/ai-instructions (1 stars, last pushed 14d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 646 tokens. 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 2026-10-04.
