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 | $0.00008 | $0.02329 |
| Sonnet 5 | $0.00003 | $0.00932 |
| Haiku 4.5 | $0.00002 | $0.00466 |
Grade B, and why
convert-project-to-starter-kit scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.
**If target has no `.claude/settings.json`:** Copy `$SOURCE/.claude/settings.json` directly. How it starts

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.confAND.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
$TARGET - If no path AND CWD is NOT the starter kit (no
claude-mastery-project.confin CWD) → use CWD as$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)
$TARGETdirectory exists → if not: "Directory not found: $TARGET"$TARGETis 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."
- If not a git repo: "This project must be a git repo. Run
$TARGETis NOT the starter kit itself (compare resolved paths of$SOURCEand$TARGET)- If same: "Cannot convert the starter kit itself. Provide the path to an existing project."
$SOURCEhas 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"
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.

convert-project-to-starter-kit is a command published in the GitHub repository TheDecipherist/claude-code-mastery-project-starter-kit (338 stars, last pushed 2mo ago), licensed MIT. It adds 16 tokens to every session and 4,659 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

checklist
Generate a custom checklist for the current feature based on user requirements.
clarify
Identify underspecified areas in the current feature spec by asking up to 5 highly targeted clarification questions and encoding answers back into the spec.
specify
Create or update the feature specification from a natural language feature description.
converge
Assess the current codebase against the feature's spec, plan, and tasks, then append any remaining unbuilt work as new tasks to tasks.md so implement can complete it.
implement
Execute the implementation plan by processing and executing all tasks defined in tasks.md.
analyze
Perform a non-destructive cross-artifact consistency and quality analysis across spec.md, plan.md, and tasks.md after task generation.
