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 | $0.00053 | $0.01164 |
| Opus 5 | $0.00026 | $0.00582 |
| Sonnet 5 | $0.00011 | $0.00233 |
| Haiku 4.5 | $0.00005 | $0.00116 |
Grade A, and why
context-service-guide 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 8d 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.
How it starts
The opening of the file, as written. The whole thing — 111 lines — stays where its author put it; the contents beside it link to each section on GitHub.
⚠️ Legacy WildFly context services only. The patterns in this skill —
cpp-context-*Maven multi-modules,-command-api/-query-api/-domain-event, RAML, custom CQRS plumbing,subscriptions-descriptor.yaml— are WildFly-era patterns and must not be applied to new Spring Boot services. They exist here to help engineers onboard to existing services.For new Spring Boot services, use
skills/springboot-service-from-template/. For new HMCTS Marketplace API specs, useskills/springboot-api-from-template/. Cross-pollinating these patterns into a Spring Boot service is a design regression — the master source for Spring Boot is the HMCTS template (seecontext/tech-stack.md).
Context Service Guide
Provides a structured walkthrough of any CP context service repository to help developers quickly understand its purpose, structure, integrations, and development workflow.
When to Use
- User asks to "explain this context service", "walk me through this repo", "what does this service do"
- User is new to a
cpp-context-*repo and wants to understand it - User asks about a service's domain events, commands, queries, or integrations
Process
Step 1: Identify the Context Service
Determine which cpp-context-* repo the user is asking about. If they're in a subdirectory, resolve to the repo root.
Step 2: Read Key Files
Read these files in parallel to build a complete picture:
pom.xml(root) — parent POM, modules list, properties, dependency versionsREADME.md— if present, provides an overview*-domain/*-domain-event/src/main/resources/json/schema/— domain event schemas reveal what the service publishes*-command/*-command-api/src/raml/— command API RAML definitions reveal what operations the service accepts*-query/*-query-api/src/raml/— query API definitions reveal what data the service exposes*-viewstore-liquibase/— Liquibase changelogs reveal the read-model database schema*-event-sources/— event source configurations reveal what events from other contexts this service subscribes to
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.

context-service-guide is a skill published in the GitHub repository hmcts/agentic-plugins-marketplace (3 stars, last pushed yesterday), licensed MIT. It adds 53 tokens to every session and 1,164 once invoked, about $0.0003 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.
