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 | $0.00049 | $0.00422 |
| Opus 5 | $0.00024 | $0.00211 |
| Sonnet 5 | $0.00010 | $0.00084 |
| Haiku 4.5 | $0.00005 | $0.00042 |
Grade A, and why
paw-persistence-contracts-layer 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 11d 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
Paw Persistence Contracts Layer
Overview
Use this for persistence-contracts/, the module that lets services depend on DAO abstractions instead of JDBC implementations.
Read references/layer-rules.md before changing DAO contracts.
Workflow
- Inspect existing DAO interfaces in
persistence-contracts/src/main/java/ar/edu/itba/paw/persistence. - Resolve stage: TP1 contracts must be implementable with JDBC SQL; TP2 contracts may be implemented by JPA but still must not leak ORM details.
- Define the contract from the service use case, not from a planned SQL/JPA implementation.
- Keep signatures free of
java.sql,JdbcTemplate, row mappers,EntityManager, JPQL strings, servlet/web types, and implementation classes. - Prefer
PageRequest, sort/filter domain objects, and domain return types over loose offset/limit or raw maps. - Add batch contracts when a web/service flow would otherwise call a DAO once per row.
- Update persistence implementation and tests in the same feature slice unless the user explicitly asks for contracts only.
Contract Rules
- One table should have one owning DAO for writes.
- DAO contracts can expose query intent but not SQL plumbing.
- Return empty lists/pages instead of
null. - Use
Optionalonly if the existing DAO style supports it for that absence case. - Keep names behavior-oriented:
findByRestaurantId,countFeedReviews,findReassignableForReservations.
Verification
- Contract-only compile:
mvn -pl persistence-contracts -am test. - Contract plus JDBC implementation:
mvn -pl persistence -am test. - Contract used by services/webapp:
mvn -pl webapp -am testor broader.
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.

paw-persistence-contracts-layer is a skill published in the GitHub repository keodubo/PAW-Wiki (10 stars, last pushed 1mo ago), licensed MIT. It adds 49 tokens to every session and 422 once invoked, about $0.0002 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.
