.claude/commands/create-codemap.md

create-codemap is a command for Claude Code from SYZ-Coder/codebase-knowledge-wiki. It costs 18 tokens per session (206 once invoked), scanned A, original, MIT.

A code knowledge map for a project, group of related services, feature, or service chain. It records findings from the code in Markdown files.

In plain words
What is it for?
Scan a workspace, classify its structure, and create evidence-based documentation under mydocs/codemap/.
Why use it?
It gives you a documented view of how a codebase is organised and marks conclusions that are incomplete or based only on clues.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

create-codemap scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Use the backend service spec skill as the primary workflow.

Read the skill source from the first available location:

  • .claude/skills/backend-service-spec-skill/SKILL.md
  • skills/backend-service-spec-skill/SKILL.md
  • ai-skill-lib/backend-service-spec-skill/SKILL.md
  • backend-service-spec-skill/SKILL.md

Then execute the create_codemap workflow for:

$ARGUMENTS

Before deep scanning, classify the workspace as single-system, service-family, or multi-system-workspace.

Generate Markdown artifacts under mydocs/codemap/ unless the user gives another path. Keep conclusions grounded in code evidence and mark unresolved items as clue-level or partial evidence.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
