Implements agent-readiness on public sites and docs from Mintlify Agent Score, AFDocs, Is Agentic, Is It Agent Ready, or url-discovery-bench reports, or from server logs of agents 404ing on guessed URLs. Use when asked to "make our site agent-ready", "improve Agent Score", "fix llms.txt coverage", "agents keep 404ing on our docs", or when a pasted scorecard is the brief.

Cuts the wait from push to green by measuring a pipeline's critical path from run timestamps, then splitting, sharding, trimming setup and sharing test module state, with a before/after ledger. Use when asked to "speed up CI", "CI is slow", "why does a PR take 15 minutes", "CI is the bottleneck", or when agents merge faster than checks finish.

Designs module interfaces, deepens shallow modules, and installs enforceable repository guardrails and agent wayfinding. Use when asked to "design the architecture", "simplify our modules", "find shallow modules", "harden the repo", or "gate an unattended agent fix job".

Audits libraries, CLIs, and SDKs using 38 rules for public contracts, package exports, piped output, errors, and configuration. Use when asked to "audit my CLI", "review my SDK", or diagnose package type resolution.

For general module structure use codebase-architecture; for SEO content use seo.

Monitors or repairs an open GitHub PR: CI failures, conflicts, review threads, and merge readiness, reporting state changes. Use when asked to "watch this PR", "fix CI", "resolve conflicts", or "address review comments".

Guidance for working on the language model prompts that power the Mossback support assistant and the document summariser. Covers system prompts, prompt templates, few-shot examples, model selection, model parameters, temperature, token limits, context windows, tool definitions, structured output, response parsing, and prompt versioning. Also covers how prompts are stored, how a prompt change is rolled out behind a flag, how to compare two prompt versions on the saved transcript set, and how to read the comparison report. Helps with improving answer quality, reducing hallucination, shortening responses, and switching to a different model. Use when the user mentions a prompt, the assistant, the summariser, an LLM, a language model, a model, tokens, temperature, or AI behaviour, or asks why the assistant said something or how to make it respond differently. Always follows the Mossback platform conventions, house style, and established best practices.

Explains and changes how Saltmarsh Booking computes refunds for cancelled stays. Use when asked to "change the refund window", "why was this guest refunded this amount", or "add a cancellation rule".

Saves a named source to Markdown with provenance and faithful extraction through direct export endpoints. Use when asked to "save this article", "get the markdown", "transcribe this", or "keep this source". A URL supplied as task context alone does not trigger conversion; a chat summary stays in chat.
