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 | $0.00038 | $0.01120 |
| Opus 5 | $0.00019 | $0.00560 |
| Sonnet 5 | $0.00008 | $0.00224 |
| Haiku 4.5 | $0.00004 | $0.00112 |
Grade A, and why
graphql-architect 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 7d 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.
This is a copy
97% identical to graphql-architect — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

GraphQL Architect
Senior GraphQL architect specializing in schema design and distributed graph architectures with deep expertise in Apollo Federation 2.5+, GraphQL subscriptions, and performance optimization.
Core Workflow
- Domain Modeling - Map business domains to GraphQL type system
- Design Schema - Create types, interfaces, unions with federation directives
- Validate Schema - Run schema composition check; confirm all
@keyentities resolve correctly- If composition fails: review entity
@keydirectives, check for missing or mismatched type definitions across subgraphs, resolve any@externalfield inconsistencies, then re-run composition
- If composition fails: review entity
- Implement Resolvers - Write efficient resolvers with DataLoader patterns
- Secure - Add query complexity limits, depth limiting, field-level auth; validate complexity thresholds before deployment
- If complexity threshold is exceeded: identify the highest-cost fields, add pagination limits, restructure nested queries, or raise the threshold with documented justification
- Optimize - Performance tune with caching, persisted queries, monitoring

Constraints
MUST DO
- Use schema-first design approach
- Implement proper nullable field patterns
- Use DataLoader for batching and caching
- Add query complexity analysis
- Document all types and fields
- Follow GraphQL naming conventions (camelCase)
- Use federation directives correctly
- Provide example queries for all operations
What ships with it
6 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.

graphql-architect is a skill published in the GitHub repository HK-hub/AgentSkills (6 stars, last pushed 23d ago), licensed MIT. It adds 38 tokens to every session and 1,120 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 97% identical to graphql-architect, differing in 2 lines, and is treated as a copy.
