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 | $0.00203 | $0.00684 |
| Opus 5.5 | $0.00081 | $0.00274 |
| Sonnet 5.5 | $0.00041 | $0.00137 |
| Haiku 4.5 | $0.00020 | $0.00068 |
Grade A, and why
jpa-persistence 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 today.
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
JPA Persistence
Instructions
Build the persistence layer of the use case $ARGUMENTS with Spring Data JPA: @Entity classes named after the
entity model, Spring Data repositories, and projections the service maps into records inside its transaction.
Scope
- Consumes the Handover of the migration layer, or the existing migrations when run directly.
- Produces the entities, repositories, and query methods the service layer calls.
- Never touches migrations, services, controllers, views, tests, or anything under
docs/other than the Markers table ofdocs/architecture/stack.md.
Run Directly or from /use-case-implement
Run from /use-case-implement, this skill inherits the inputs that skill read, the gaps the user answered, and its
rules for reconciling an existing implementation; it does not repeat the status check or ask the same questions
again. Run directly, read the use case, the requirements it links, docs/entity_model.md, and
docs/architecture/stack.md yourself, and stop on a Draft or Reviewed use case.
Business Rule Markers
Put // UC-XXX BR-YYY: <rule> directly above the repository query method, exists…/count… check, or @Version
field that enforces the rule.
Markers
Keep this skill's rows in the Markers table of docs/architecture/stack.md exactly as
references/markers.md lists them: add them when they are missing, correct them when they
differ. Touch no other row.
Handover
Handover from jpa-persistence (UC-XXX)

- <return type> <method>(<parameters>)
Nothing to do: <reason>
What ships with it
2 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.

jpa-persistence is a skill published in the GitHub repository AI-Unified-Process/marketplace (150 stars, last pushed yesterday), licensed Apache-2.0. It adds 203 tokens to every session and 684 once invoked, about $0.0008 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 2026-10-25.
