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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00145 | $0.00728 |
| Opus 5.5 | $0.00058 | $0.00291 |
| Sonnet 5.5 | $0.00029 | $0.00146 |
| Haiku 4.5 | $0.00015 | $0.00073 |
Grade A, and why
512-frameworks-micronaut-data 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 27d 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 — 67 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Micronaut Data Guidelines
Apply Micronaut Data patterns for relational repositories and safe SQL.
What is covered in this Skill?
- @MappedEntity, @Id, @GeneratedValue, @MappedProperty for column mapping
- @Repository interfaces extending CrudRepository / PageableRepository
- Derived finder methods and @Query with named parameters
- @Transactional on @Singleton services (readOnly where appropriate)
- Page and Pageable for list endpoints
- DTO/interface projections for read-heavy queries
- @Version for optimistic locking
- Integration tests: @MicronautTest + TestPropertyProvider + Testcontainers
Scope: Apply recommendations based on the reference rules and good/bad code examples.
Constraints
Compile before persistence changes; verify the full build after.
- MANDATORY: Run
./mvnw compileormvn compilebefore applying any change - SAFETY: If compilation fails, stop immediately
- VERIFY: Run
./mvnw clean verifyormvn clean verifyafter applying improvements - BEFORE APPLYING: Read the reference for detailed rules and examples
- EDGE CASE: If the user goal is ambiguous, stop and ask a clarifying question before editing files or running project-wide commands
- EDGE CASE: If required context, files, credentials, or tools are missing, report the blocker explicitly and ask whether to proceed with setup or fallback guidance
- EDGE CASE: If requested changes conflict with project constraints or safety boundaries, explain the conflict and ask for user confirmation on the preferred trade-off
When to use this skill
- Review or implement Micronaut Data repositories and entities
- Add transactions, pagination, or projections in Micronaut persistence layer
- Model Micronaut Data entities and repositories
- Review Micronaut Data transactions and pageable queries
- Improve projections or optimistic locking with Micronaut Data
Workflow
- Read reference and assess project context
Read references/512-frameworks-micronaut-data.md and inspect the current project setup before proposing changes.
What ships with it
1 file 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.

512-frameworks-micronaut-data is a skill published in the GitHub repository jabrena/plinth (455 stars, last pushed 3d ago), licensed Apache-2.0. It adds 145 tokens to every session and 728 once invoked, about $0.0006 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.
