What Palace Architect is
Palace Architect is a subagent published in the athola/claude-night-market repository on GitHub, which has about 339 stars. The repository describes itself as: “23 Claude Code plugins: TDD enforcement hooks, git/PR workflows, spec-driven development, code review, project lifecycle, fix-from-error, maintenance automation, context optimization, research, and multi-LLM delegation. 186 skills, 128 commands, 54 agents.”
A subagent is a specialist assistant that Claude can hand part of a task to. It is a markdown file whose frontmatter sets a name, a description that tells Claude when to delegate, and optionally the tools and model it may use; the body becomes the subagent's own system prompt.
Because a subagent works in its own context, it keeps the main conversation focused: Claude can send a narrow job, such as a review or a specialised analysis, to Palace Architect and get back a compact result.
It is set up to use these tools: Read, Write, Bash, Grep, Glob. Limiting tools is a good sign: the subagent can only do what those tools allow.
How to install Palace Architect
Claude Code
- Download palace-architect.md from the repository.
- Save it to ~/.claude/agents/ to use it in every project, or to .claude/agents/ inside one project to share it through version control.
- Claude Code watches these folders, so the subagent is usually available right away. Ask Claude to use it by name, or @-mention it to make sure it runs.
Claude Cowork
- Cowork loads subagents through plugins. If the repository is packaged as a plugin marketplace, add it under Customize → Plugins → Add marketplace and install the plugin that contains this subagent.
- Otherwise, bundle the file into your own plugin's agents/ folder and upload it from Customize → Plugins.
New to extending Cowork? Our plugins guide and Customize guide explain how skills, plugins, and connectors fit together.

Designs and constructs virtual memory palaces for spatial knowledge organization.
Capabilities
- Analyzes knowledge domains for optimal spatial mapping
- Designs architectural layouts reflecting conceptual relationships
- Creates multi-sensory associations for enhanced recall
- Builds navigable structures for knowledge retrieval
- Validates palace effectiveness with recall metrics
Design Process
- Domain Analysis: Identify core concepts, relationships, and hierarchy
- Layout Design: Choose metaphor and spatial organization
- Association Mapping: Create memorable imagery and connections
- Sensory Encoding: Add multi-sensory details for recall
- Validation: Test navigation and recall efficiency
Usage
When dispatched, provide:
- The knowledge domain to organize
- Preferred architectural metaphor (optional)
- Specific concepts to include (optional)
Create a memory palace for [domain] using a [metaphor] structureOutput
Returns palace specification with:
- Spatial hierarchy (districts, buildings, rooms)
- Sensory encoding for each location
- Navigation paths and connections
- Validation metrics and recommendations
Implementation
Uses the palace_manager.py tool for palace creation:
python ${CLAUDE_PLUGIN_ROOT}/src/memory_palace/palace_manager.py create "<name>" "<domain>" --metaphor <type>Before you install
- Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
- Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
- Try it in a test project or a copy of your files before pointing it at real work.
- Pin the version you tested, and review changes before updating.
- Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
