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 | $0.00240 | $0.00905 |
| Opus 5 | $0.00120 | $0.00452 |
| Sonnet 5 | $0.00048 | $0.00181 |
| Haiku 4.5 | $0.00024 | $0.00090 |
Grade A, and why
api-platform-filters 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 5d 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 — 48 lines — stays where its author put it; the contents beside it link to each section on GitHub.
API Platform 4.3 — Filters (modern parameters pattern)
Use when
- Adding any query filter, sort, range, or full-text search to a
GetCollection. - Replacing existing
#[ApiFilter]annotations (legacy) with the 4.3 modern pattern. - Implementing a custom filter via
FilterInterface+ Json Schema + OpenAPI traits. - Wiring a Parameter Provider (IRI converter, read link, custom dynamic group).
- Enforcing multi-tenant row-level security via a Doctrine SQL Filter.
Default workflow
- Identify the columns that must be filterable, sortable, or full-text searchable.
- Declare
parameters: [...]on the operation with onenew QueryParameter(filter: new XxxFilter(), property: '...')per parameter. - Add
castToNativeType/castToArray/castFnwhere the value needs a type or transformation. - Index every filtered column (
#[ORM\Index]) and a functional index for case-insensitive partial searches. - Write tests that exercise each filter + boundary cases.
Guardrails
propertyis mandatory in 4.3 onExactFilter,IriFilter,PartialSearchFilter,UuidFilter— otherwiseInvalidArgumentExceptionat compile time. Use the literal property name or the:propertyplaceholder.- Never use
#[ApiFilter]orextends AbstractFilterin new code — both are deprecated since 4.2 and removed in 5.0. IriFilterfor FKs, never anExactFilteron a scalaruserId(IRI-only rule).- Indexing is non-optional — without an index, a filter becomes a full scan.
PartialSearchFiltersparingly — a case-insensitive partial search bypasses btree indexes; add a functional index onLOWER(col)when used.

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.

api-platform-filters is a skill published in the GitHub repository gerard-labs/superpowers-api-platform (2 stars, last pushed 3mo ago), licensed MIT. It adds 240 tokens to every session and 905 once invoked, about $0.0012 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.
