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 | $0.00382 | $0.00382 |
| Opus 5 | $0.00191 | $0.00191 |
| Sonnet 5 | $0.00076 | $0.00076 |
| Haiku 4.5 | $0.00038 | $0.00038 |
Grade A, and why
SidewalkWebpage scala.instructions.md 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 3d 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
Backend / v3 API review
- v3 API casing (
/v3/api/...): query/REST parameters are camelCase (minSeverity,regionId); all output field names are snake_case — JSON bodies, GeoJSONproperties, CSV headers, GeoPackage fields (label_id,region_name). Flag a snake_case query param or a camelCase output field. Use a scopedJsonConfiguration(JsonNaming.SnakeCase)for macro writers. EXCEPTION: Shapefile/DBF fields stay camelCase + abbreviated (DBF truncates names to 10 chars). - API DTO home: new response/filter DTOs go in
app/models/api/(package models.api), named*ForApi/*FiltersForApi, extendingStreamingApiTypewith inlinetoJson/toCsvRowandcsvHeaderin the companion. Flag new API DTOs defined inside a*Table.scalafile. - Layering: controllers stay thin — business logic in
app/service/, DB access inapp/models/*Table.scala. Flag a controller querying tables directly. - SQL: no table aliases in Slick/plain SQL.
- ScalaDoc:
/** */on every class/trait/object and non-trivial method (including private). Use@return(not@returns); don't repeat the type in@param. Flag comments that narrate a change rather than state current behavior. -Xfatal-warningsis on: flag unused imports/params, dead code, and discarded non-Unit results — they fail the build.
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.

SidewalkWebpage scala.instructions.md is an instructions file published in the GitHub repository ProjectSidewalk/SidewalkWebpage (104 stars, last pushed 4d ago), licensed MIT. It adds 382 tokens to every session, about $0.0019 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 2026-08-30.
