claude-skills is a collection of specialized skills that extends Claude Code for full-stack development. Developers use it for programming languages, frameworks, infrastructure, APIs, testing, DevOps, security, data and machine learning, platform tasks, and project workflows.
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.

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 5.1 | $0.00038 | $0.01144 |
| Opus 5 | $0.00019 | $0.00572 |
| Sonnet 5 | $0.00008 | $0.00229 |
| Haiku 4.5 | $0.00004 | $0.00114 |
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 10d 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.

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 Jeffallan/claude-skills (11,401 stars, last pushed 1mo ago), licensed MIT. It adds 38 tokens to every session and 1,144 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 2026-08-30.
