Why use it?
It helps keep technical documentation factual and aligned with how the software currently works.

Command for Claude Code

About the project

MockServer is a testing server and proxy that imitates APIs, records and changes network traffic, and deliberately introduces failures. It is for developers testing applications against unavailable dependencies, debugging requests, and checking how systems handle degraded services across several network protocols. The catalogue add-ons help operate, configure, and test MockServer.

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.

Security

Grade A, and why

update-architecture-docs 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 5d 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

Use the Agent tool to spawn a docs-writer subagent to review architecture documentation against the codebase and update docs for the following request:

$ARGUMENTS

The docs-writer agent will:

  1. Compare current docs with actual code behavior.
  2. Apply minimal, factual updates only where drift is found.
  3. Cite source paths that justify each documentation change.
  4. When restructuring or adding sections, follow the outcome-first skeleton in .opencode/rules/documentation-style.md (Pyramid Principle with progressive disclosure) — lead with the takeaway, then layer detail beneath it.

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.
