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 | $0.00047 | $0.01418 |
| Opus 5 | $0.00023 | $0.00709 |
| Sonnet 5 | $0.00009 | $0.00284 |
| Haiku 4.5 | $0.00005 | $0.00142 |
Grade A, and why
angular-19 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.
The source is not reproduced here
No licence file
A repository with no LICENSE is all rights reserved by default, so the body is not copied here. The metadata, the measurements and the link are.
What ships with it
3 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.

angular-19 is a skill published in the GitHub repository robiparvez/claude-code-guidelines (2 stars, last pushed 25d ago), with no licence file. It adds 47 tokens to every session and 1,418 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.
Other skills, from other repositories
spring-boot-4-conventions
Spring Framework 7 / Spring Boot 4 idioms and defaults. Use when writing or reviewing controllers, services, configuration, HTTP clients, async/virtual-thread code, or anything touching Spring's programming model.
performance-optimization
Spring Boot 4 / JVM performance work — measure first, then fix. Profiling (async-profiler, JFR, JMH), Micrometer, common Spring antipatterns (N+1, unbounded lists, HikariCP sizing, virtual-thread pinning), caching, GC, and SLO-driven work. Used by /plan for risk callouts and by /review to flag perf regressions.
maven-harness-pom
Reference Maven POM fragments for the full harness — Spotless, Checkstyle, SpotBugs, Error Prone, JaCoCo, PIT, OpenAPI generator + diff, OWASP dependency check, Surefire/Failsafe. Use when wiring the harness into a new project or upgrading a brownfield POM.
shipping-and-launch
Pre-deploy hygiene for a Spring Boot 4 feature — verify gates, capture rollback plan, sign off observability, generate release notes, and stage the rollout. Used by /ship after /review approves the diff. The agent never deploys; it produces the plan a human executes.
clarity-over-cleverness
Apply clarity-over-cleverness rewrites — prefer code a junior engineer can read at a glance over compact-but-clever code. Use during /build's simplify step and during /code-simplify (alias "simplify the code"). Never weakens behavior; suite must remain green.
junit5-testcontainers-patterns
JUnit 5 + Spring Boot 4 test slice patterns and Testcontainers integration test patterns with @ServiceConnection. Use when writing or reviewing any test, especially when choosing between unit / slice / integration scope.
