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 | $0.00099 | $0.00372 |
| Opus 5 | $0.00049 | $0.00186 |
| Sonnet 5 | $0.00020 | $0.00074 |
| Haiku 4.5 | $0.00010 | $0.00037 |
Grade A, and why
springboot-conventions 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 4d 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.
What it actually says
Spring Boot Conventions
The rules enforced by the guardrail hook (ruleset.json) and the always-on summary
in CLAUDE.md are deliberately terse. This skill holds the rationale and the fix
patterns, split by domain so you only load what's relevant.
Load the reference for the layer you're in:
| You're working on… | Read | Covers rules |
|---|---|---|
| Entities, repositories, queries | references/persistence.md |
jpa-optimistic-lock, jpa-entity-equals, nplus1-heuristic, jpql-injection |
| Controllers, request/response | references/web.md |
entity-in-controller |
Service methods, @Transactional |
references/transactions.md |
tx-proxy |
| Tests | references/testing.md |
(slice tests, Testcontainers) |
Each reference explains: the failure mode, why it bites, the correct pattern, and how
to suppress the guardrail (// jbt:ignore <rule-id>) when a deviation is intentional.
This is reference material, not a tutorial — it assumes you know Spring Boot and focuses on the mistakes that are easy to miss.
What ships with it
6 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.

springboot-conventions is a skill published in the GitHub repository ShipWithAI/shipwithai-plugins (10 stars, last pushed 22d ago), licensed MIT. It adds 99 tokens to every session and 372 once invoked, about $0.0005 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.
