Skill Suite

The universal installer ships a small skill suite next to the MCP configuration for every host with a skill/command surface: Claude Code (~/.claude/skills/), Codex CLI and Codex Desktop (~/.codex/skills/, the open agent-skills standard), and OpenCode (~/.config/opencode/commands/). Hosts without a surface are skipped automatically. Opt out with --no-skills (PowerShell: -NoSkills).

Skill	What it does
`crystal-brief`	Session bootstrap: verifies the MCP server responds, loads context, then applies the mandatory memory discipline (identical, by lockstep test, to the homepage agent prompt).
`crystal-kb`	Knowledge-base workflows: import with mandatory `dedupeKey` (one key = one chunk), enumerate, edit, empty-in-place, agent access, and reading per-agent priorities.
`crystal-architect`	Documents a codebase into a re-runnable `Architecture: <repo>` knowledge base with deterministic `arch:*` dedupeKeys — refreshes in place, never duplicates.
`crystal-hygiene`	Conversational-memory cleanup under the freshness policy: every fact is timeless, dated, or a pointer; contradictions resolve via `crystal_supersede`, never silent deletion.
`crystal-checkpoint`	Milestone ritual: checkpoint + a durable summary memory, verified.

Skills only ever call Memory Crystal’s MCP tools — they never edit agent config files. If the tools are missing, every skill stops and points you at the installer.

Current endpoints

The canonical API base is https://convex.memorycrystal.ai (MCP: https://api.memorycrystal.ai/mcp). Legacy Convex-generated hosts — rightful-mockingbird-389.convex.cloud/.convex.site and earlier — were decommissioned on 2026-07-14 and return errors for every request. The installer migrates configs it manages automatically; if an agent reports 500s from a legacy host, re-run the installer.
