A command that merges Claude instruction files from a local path or remote Git repository into the current project, while asking the user to decide how each change should be handled.

Use it to sync instruction files from a repository or folder and focus the merge on specific guidance, such as Git rules.

It helps bring shared project rules into a repository without silently overwriting existing instructions or making every merge decision automatically.

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	$0.00019	$0.11898
Opus 5	$0.00010	$0.05949
Sonnet 5	$0.00004	$0.02380
Haiku 4.5	$0.00002	$0.01190

Security

Grade D, and why

sync scanned grade D with 2 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 10d 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.

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

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Claude-Dogma: Intelligent Sync of Claude Instructions

You are executing the /claude-dogma command. Your task is to intelligently merge Claude instruction files from a source into the current project with user interaction for every decision.

Configuration

DEFAULT_SOURCE="https://github.com/Marcel-Bich/marcel-bich-claude-dogma"

Step 1: Parse Arguments

The user provided: $ARGUMENTS

Parse into SOURCE and INSTRUCTIONS (order does not matter, quotes optional):

Source detection (recognizable patterns):

Starts with http:// or https:// = Remote Git repo
Starts with ~/, ./, ../, / = Local path

Instructions detection:

Everything else that is NOT a recognizable source pattern
Quotes "..." are optional but recommended for clarity

Valid combinations:

/dogma:sync                                         -> DEFAULT_SOURCE, no instructions
/dogma:sync ~/source                                -> ~/source, no instructions
/dogma:sync focus on git rules                      -> DEFAULT_SOURCE, instructions
/dogma:sync "focus on git rules"                    -> DEFAULT_SOURCE, instructions
/dogma:sync ~/source focus on git rules             -> ~/source, instructions
/dogma:sync ~/source "focus on git rules"           -> ~/source, instructions
/dogma:sync "focus on git rules" ~/source           -> ~/source, instructions
/dogma:sync focus on git rules ~/source             -> ~/source, instructions

If user provided instructions, display them and follow throughout:

User instructions: "<instructions>"
Will follow these throughout the sync process.

If DEFAULT_SOURCE is "TODO_CONFIGURE_DEFAULT_SOURCE" and no source provided: Stop and tell the user: "Default source not configured. Please provide a source URL or path."

Step 2: Fetch Source to Temporary Directory

For Remote Repos

TEMP_DIR=$(mktemp -d)
git clone --depth 1 --branch main <REPO_URL> "$TEMP_DIR" 2>&1
if [ $? -ne 0 ]; then
    rm -rf "$TEMP_DIR"
    # Report error and stop
fi
SOURCE_DIR="$TEMP_DIR"

sync is a command published in the GitHub repository Marcel-Bich/marcel-bich-claude-marketplace (13 stars, last pushed today), licensed MIT. It adds 19 tokens to every session and 11,898 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it D with 2 findings (reads agent configuration directories, recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
