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 | $0.01186 | $0.01186 |
| Opus 5.5 | $0.00474 | $0.00474 |
| Sonnet 5.5 | $0.00237 | $0.00237 |
| Haiku 4.5 | $0.00119 | $0.00119 |
Grade A, and why
ai-instructions spring-boot-container.instructions.md 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 1mo 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 — 113 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Spring Boot Container Contract
These rules govern container images and Compose-based orchestration for Spring Boot projects. They are generic container rules. Service-specific contracts own the configuration and behavior of databases, brokers, caches, secret stores, and proxies.
Ownership
- Defer application YAML, profiles, and secrets to
spring-boot-config.instructions.md. - Defer HTTPS and certificate handling to
spring-boot-tls.instructions.md. - Defer certificate and secret-file ignore patterns to
spring-boot-gitignore.instructions.md. - Defer health endpoint exposure and authorization to
spring-boot-actuator.instructions.mdandspring-boot-security.instructions.md. - Defer human-facing container commands and prerequisites to
spring-boot-readme.instructions.md. - Keep service-specific infrastructure settings in the contract for that service.
Image builds
- Use a multi-stage build for deployable application images.
- Keep compilation and dependency resolution in the builder stage; keep the runtime stage limited to the application artifact and runtime requirements.
- Copy a locally built JAR into a runtime image only as an explicitly development-only workflow.
- Use a base image whose Java runtime matches the project's configured Java version.
- Prefer maintained minimal runtime images. Custom base images are optional, but their Java version, user, filesystem layout, and update process must be documented.
- Pin image references to explicit versions. Use immutable digests for production deployments when the deployment platform supports them.
- Keep build context small with a focused
.dockerignore. - Do not copy source-controlled secrets, local environment files, build caches, or unrelated workspace files into an image.
Runtime identity and hardening
- Run application containers as a non-root user.
- Declare or verify the runtime user explicitly; do not rely on undocumented base-image behavior.
- Drop Linux capabilities with
cap_drop: ALLunless a documented runtime requirement needs a specific capability. - Set
no-new-privileges:truefor application and infrastructure services by default. - Use a read-only root filesystem with a narrowly scoped
tmpfsfor writable temporary paths when the process supports it. - Mount certificates, configuration, and persistent data read-only unless the process must write them.
- Do not grant privileged mode or host namespaces without an explicit operational need.
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.

ai-instructions spring-boot-container.instructions.md is an instructions file published in the GitHub repository lsampaioweb/ai-instructions (1 stars, last pushed 5d ago), licensed MIT. It adds 1,186 tokens to every session, about $0.0047 per session on Opus 5.5. 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 2026-09-03.
