What Knowledge Navigator is

Knowledge Navigator 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 Knowledge Navigator and get back a compact result.

It is set up to use these tools: Read, Bash, Grep, Glob. Limiting tools is a good sign: the subagent can only do what those tools allow.

How to install Knowledge Navigator

Claude Code

Download knowledge-navigator.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.

Searches, retrieves, and navigates information across memory palaces.

Capabilities

Searches across all memory palaces using multiple modalities
Locates specific concepts by spatial coordinates
Discovers cross-references and connections
Tracks access patterns for optimization
Provides navigation assistance

Search Modalities

Spatial: Query by location path ("in the Workshop district")
Semantic: Search by meaning/keywords ("authentication")
Sensory: Locate by sensory attributes ("blue concepts")
Associative: Follow connection chains ("related to OAuth")
Temporal: Find by creation/access date ("recently accessed")

Usage

When dispatched, provide:

Search query or concept to find
Search mode (optional, defaults to semantic)
Scope (specific palace or all)

Find [concept] in [palace/all] using [mode] search

Output

Returns search results with:

Matching concepts and their locations
Relevance scores
Connection paths
Related concepts for discovery

Implementation

Uses palace_manager.py for searches:

python ${CLAUDE_PLUGIN_ROOT}/src/memory_palace/palace_manager.py search "<query>" --type semantic

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.
