A GraphQL gateway for web applications that combines data from separate services into one API. It acts as a backend tailored to frontend queries.

Use it to resolve cross-service GraphQL queries, combine related records, and serve frontend or BFF requests efficiently.

It keeps web clients from calling many services separately and prevents database access from being scattered through the gateway.

Token cost

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	$0.00040	$0.00226
Opus 5	$0.00020	$0.00113
Sonnet 5	$0.00008	$0.00045
Haiku 4.5	$0.00004	$0.00023

Security

Grade A, and why

cmd/gateway 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 2d 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

GraphQL Gateway (cmd/gateway & internal/transport/graphql)

This module acts as the Backend-For-Frontend (BFF). It receives optimized GraphQL queries from the web clients and fans out requests across the isolated micro-domains, stitching the Golden Threads (UUIDs) back together in memory.

Constraints

Zero Raw SQL: The Gateway must never touch Cloud Spanner directly. It can only call the domain Service interfaces.
Dataloading: Resolvers must batch their physical reads via N+1 safe graph loaders when traversing down the Golden Thread.

Files

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.

Changes

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.

cmd/gateway is a skill published in the GitHub repository quantDIY/GERP (3 stars, last pushed 5mo ago), licensed MIT. It adds 40 tokens to every session and 226 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.

Stage playbook for executing steps of the change formula v2 (ADR-0075) — the 5-step molecule that takes a request from spec to merged PR. Use when claiming or executing any bead poured from the change formula (spec, spec-approval, build, verify, pr), when parking a stuck step, or when recording a spec approval. Covers…

Derive NeoHaskell concepts (Query, Command, Event, Outbound integration) through their canonical Template Haskell marker instead of hand-writing the instances the marker generates. Use whenever creating or editing a query, command, event, entity, or any concept that has a TH marker — reach for deriveQuery / command /…

neohaskell-security-design-review

Design-time security review of an approved contract-delta spec, before implementation. Runs when the spec's touches list intersects security-sensitive capabilities. Produces a LOCAL-only review record (gitignored, never pushed — a security review maps attack surface); enforced on the dev machine, not in CI.

neohaskell-localizer

Route a request to exact code locations using the codemap — capability lookup, extension points for new code, signature grep, edit-set expansion. Use at PLAN time, before any implementation; execution must never search.
