Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.
npx agentmods add commands/leoyang183/sync-agents-settings/sync-diffgit clone --depth 1 https://github.com/Leoyang183/sync-agents-settingsWhat 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 | $0.00015 | $0.00296 |
| Opus 5 | $0.00008 | $0.00148 |
| Sonnet 5 | $0.00003 | $0.00059 |
| Haiku 4.5 | $0.00002 | $0.00030 |
Grade A, and why
sync-diff 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 yesterday.
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
Compare which MCP servers exist in Claude Code vs other AI agents.
Arguments
The user may pass target names: /sync-diff gemini
If no targets specified, compare all targets (gemini, codex, opencode, kiro, cursor, kimi, vibe, qwen, amp, cline, windsurf).
Optional flags:
--report json— output machine-readable JSON summary (CI-friendly)
Execution Flow
-
Parse targets from user arguments. Run:
npx sync-agents-settings diff --target <targets> -
Present the comparison for each target:
- Shared — servers that exist in both Claude and the target
- Only in Claude — servers that could be synced to the target
- Only in target — servers that exist in the target but not in Claude
-
If there are servers "Only in Claude", suggest: "Run
/syncto sync these servers to the target agents."- If
--report jsonis used, return raw JSON output and avoid text post-processing.
- If
Error Handling
- If
npxfails: suggestnpm install -g sync-agents-settingsas fallback. - Note: Codex and Vibe diff show a note instead of actual comparison (TOML format limitation).
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.

sync-diff is a command published in the GitHub repository Leoyang183/sync-agents-settings (8 stars, last pushed 5mo ago), licensed MIT. It adds 15 tokens to every session and 296 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
