What is convert-project-to-starter-kit?

A command that merges the Claude Code Starter Kit's commands, hooks, skills, rules, and project-document templates into an existing project.

It is for locating the starter kit and target project, then performing a non-destructive merge, with an optional force option.

It adds the starter kit's project setup while preserving the files already in the project.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00016	$0.04659
Opus 5.5	$0.00006	$0.01864
Sonnet 5.5	$0.00003	$0.00932
Haiku 4.5	$0.00002	$0.00466

Security

Grade B, and why

convert-project-to-starter-kit scanned grade B with 1 finding 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 2mo 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.

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

**If target has no `.claude/settings.json`:** Copy `$SOURCE/.claude/settings.json` directly.

Convert Existing Project to Starter Kit

Merge all Claude Code Starter Kit infrastructure (commands, hooks, skills, CLAUDE.md rules, project-docs templates) into an existing project. Non-destructive — preserves everything the user already has.

Arguments: $ARGUMENTS

Step 0 — Resolve Source and Target

Source (starter kit location)

Find the starter kit source directory:

If CWD has BOTH claude-mastery-project.conf AND .claude/commands/new-project.md → use CWD as source
Else read ~/.claude/starter-kit-source-path → verify it still has both files
Else ask via AskUserQuestion: "Where is the starter kit cloned?" with a text input

Store as $SOURCE.

Target (existing project)

Parse $ARGUMENTS for a path (everything that is not --force). Handle ~ expansion and ./ relative paths.

If a path argument is provided → resolve to absolute path, store as $TARGET
If no path AND CWD is NOT the starter kit (no claude-mastery-project.conf in CWD) → use CWD as $TARGET
If no path AND CWD IS the starter kit → ask via AskUserQuestion: "Which project do you want to convert? Provide the full path."

Check for --force flag in $ARGUMENTS. If present, set $FORCE=true (skips conflict prompts — uses "keep existing, add missing" for everything).

Validations (all must pass — stop with clear error if any fail)

$TARGET directory exists → if not: "Directory not found: $TARGET"
$TARGET is a git repo → run: git -C "$TARGET" rev-parse --is-inside-work-tree 2>/dev/null
- If not a git repo: "This project must be a git repo. Run git init && git commit --allow-empty -m 'init' first."
$TARGET is NOT the starter kit itself (compare resolved paths of $SOURCE and $TARGET)
- If same: "Cannot convert the starter kit itself. Provide the path to an existing project."
$SOURCE has expected starter kit files (claude-mastery-project.conf + .claude/commands/new-project.md)
- If not: "Starter kit source is incomplete. Expected claude-mastery-project.conf and .claude/commands/new-project.md"

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.
