What it does

Codebase Memory Quality is an agent skill from DmNote-App/DmNote. This skill should be used when the user asks about "dead code", "find dead code", "detect dead code", "show dead code", "dead code analysis", "unused functions", "find unused functions", "unreachable code", "identify high fan-out functions", "find complex functions", "code quality audit", "find functions nobody calls", "reduce codebase size", "refactor candidates", "cleanup candidates", or needs code quality analysis.

Its SKILL.md is about 680 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 Development, covering Code quality and Refactoring. 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 about dead code
Detect dead code
Dead code analysis
Unused functions

Example prompts

“dead code”
“find dead code”
“detect dead code”
“/codebase-memory-quality”

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 Quality loads about 683 tokens when it runs. Until then it costs about 111 tokens; SKILL.md has 182 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~111
When it runs · the whole SKILL.md, loaded when a task matches: ~683

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.

Code Quality Analysis via Knowledge Graph

Use graph degree filtering to find dead code, high-complexity functions, and refactor candidates — all in single tool calls.

Workflow

Dead Code Detection

Find functions with zero inbound CALLS edges, excluding entry points:

search_graph(
  label="Function",
  relationship="CALLS",
  direction="inbound",
  max_degree=0,
  exclude_entry_points=true
)

exclude_entry_points=true removes route handlers, main(), and framework-registered functions that have zero callers by design.

Verify Dead Code Candidates

Before deleting, verify each candidate truly has no callers:

trace_call_path(function_name="SuspectFunction", direction="inbound", depth=1)

Also check for read references (callbacks, stored in variables):

query_graph(query="MATCH (a)-[r:USAGE]->(b) WHERE b.name = 'SuspectFunction' RETURN a.name, a.file_path LIMIT 10")

High Fan-Out Functions (calling 10+ others)

These are often doing too much and are refactor candidates:

search_graph(
  label="Function",
  relationship="CALLS",
  direction="outbound",
  min_degree=10
)

High Fan-In Functions (called by 10+ others)

These are critical functions — changes have wide impact:

search_graph(
  label="Function",
  relationship="CALLS",
  direction="inbound",
  min_degree=10
)

Files That Change Together (Hidden Coupling)

Find files with high git change coupling:

query_graph(query="MATCH (a)-[r:FILE_CHANGES_WITH]->(b) WHERE r.coupling_score >= 0.5 RETURN a.name, b.name, r.coupling_score, r.co_change_count ORDER BY r.coupling_score DESC LIMIT 20")

High coupling between unrelated files suggests hidden dependencies.

Unused Imports

search_graph(
  relationship="IMPORTS",
  direction="outbound",
  max_degree=0,
  label="Module"
)

Key Tips

search_graph with degree filters has no row cap (unlike query_graph which caps at 200).
Use file_pattern to scope analysis to specific directories: file_pattern="**/services/**".
Dead code detection works best after a full index — run index_repository if the project was recently set up.
Paginate results with limit and offset — check has_more in the response.
