What it does

Codebase Memory Exploring is an agent skill from DmNote-App/DmNote. This skill should be used when the user asks to "explore the codebase", "understand the architecture", "what functions exist", "show me the structure", "how is the code organized", "find functions matching", "search for classes", "list all routes", "show API endpoints", or needs codebase orientation.

Its SKILL.md is about 580 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Backend & APIs, covering REST APIs. The repository describes itself as: Make it yours. A customizable key viewer for DJMAX RESPECT V and any game. The licence is GPL-3.0.

When your agent uses it

  • Asks to explore the codebase
  • Understand the architecture
  • What functions exist
  • Show me the structure

Example prompts

  • “explore the codebase”
  • “understand the architecture”
  • “what functions exist”
  • “/codebase-memory-exploring”

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Check if project is indexed
  2. Get a structural overview
  3. Find specific code elements
  4. Read source code
  5. Understand structure

What it can do on your machine

Read from SKILL.md and the folder at commit baac1e8. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Codebase Memory Exploring loads about 576 tokens when it runs. Until then it costs about 82 tokens; SKILL.md has 205 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~82
When it runs · the whole SKILL.md, loaded when a task matches
~576

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
This skill should be used when the user asks to "explore the codebase", "understand the architecture", "what functions exist", "show me the structure", "how is the code organized", "find functions matching", "search for classes", "list all routes", "show API endpoints", or needs codebase orientation.

Codebase Exploration via Knowledge Graph

Use graph tools for structural code questions. They return precise results in ~500 tokens vs ~80K for grep-based exploration.

Workflow

Step 1: Check if project is indexed
list_projects

If the project is missing from the list:

index_repository(repo_path="/path/to/project")

If already indexed, skip — auto-sync keeps the graph fresh.

Step 2: Get a structural overview
get_graph_schema

This returns node label counts (functions, classes, routes, etc.), edge type counts, and relationship patterns. Use it to understand what's in the graph before querying.

Step 3: Find specific code elements

Find functions by name pattern:

search_graph(label="Function", name_pattern=".*Handler.*")

Find classes:

search_graph(label="Class", name_pattern=".*Service.*")

Find all REST routes:

search_graph(label="Route")

Find modules/packages:

search_graph(label="Module")

Scope to a specific directory:

search_graph(label="Function", qn_pattern=".*services\\.order\\..*")
Step 4: Read source code

After finding a function via search, read its source:

get_code_snippet(qualified_name="project.path.to.FunctionName")
Step 5: Understand structure

For file/directory exploration within the indexed project:

list_directory(path="src/services")

When to Use Grep Instead

  • Searching for string literals or error messages → search_code or Grep
  • Finding a file by exact name → Glob
  • The graph doesn't index text content, only structural elements

Key Tips

  • Results default to 10 per page. Check has_more and use offset to paginate.
  • Use project parameter when multiple repos are indexed.
  • Route nodes have a properties.handler field with the actual handler function name.
  • exclude_labels removes noise (e.g., exclude_labels=["Route"] when searching by name pattern).
