A skill for managing installed skills and cloud tools through Sutando Cloud without opening its Marketplace interface. It can search, install, activate, update, and remove these tools, with a preview mode before changes are made.

Use it to find tools for a use case, install or activate them, check their status, update them, or remove them.

It lets an agent handle tool setup from the command line while showing planned changes first. It also checks which owned tools are missing or out of date.

marketplace — Skill for Claude Code and Codex by sonichi/sutando

Install

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.

Any agent

npx skills add sonichi/sutando --skill marketplace

Clone the repo

git clone --depth 1 https://github.com/sonichi/sutando

Made for: Claude Code, Codex.

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	$0.00075	$0.01276
Opus 5.5	$0.00030	$0.00510
Sonnet 5.5	$0.00015	$0.00255
Haiku 4.5	$0.00007	$0.00128

Security

Grade A, and why

marketplace 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 25d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/marketplace.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 101 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Marketplace

The owner is already signed in to Sutando Cloud (desktop onboarding), so everything the Marketplace UI does can be done from here: activate a cloud tool, install a local skill, update skills, remove them.

The script lives next to this file. Run it with python3:

M="<this skill's directory>/scripts/marketplace.py"
python3 "$M" find "lead enrichment"              # search (add --kind skill|cloud_tool|connector)
python3 "$M" status                              # owned vs on this machine
python3 "$M" install intent-leads campaign-runner   # PLAN only — writes nothing
python3 "$M" install intent-leads campaign-runner --yes
python3 "$M" update                              # list missing / outdated skills
python3 "$M" update --yes                        # re-fetch them (never charges)
python3 "$M" uninstall live-preview              # PLAN only
python3 "$M" uninstall live-preview --yes

Add --json for machine-readable output. One install call takes skills and cloud tools together; the script works out which is which.

How to run a setup

Collect the slugs. From the owner's request, or from a use-case doc (read it; docs list what they need under a Requires: heading). If a name isn't an exact slug, run find first.
Plan. Run install <all slugs> without --yes. Show the owner the plan in a sentence or two (what gets installed or activated, what's already set up, what's skipped and why).
Confirm when it costs something. Exit code 3 means the plan spends credits once, or activates a cloud tool that charges per use (the plan says "leads charges per use: 5 credits per result"): tell the owner the price and get their explicit OK first. Exit code 0 means it's free: go ahead. Never pass --yes to uninstall without the owner's OK.
Apply. Re-run the same command with --yes. One failed item doesn't stop the rest.
Use it now; restart only when told. A newly activated cloud tool is usable at once through station_find / station_call (the output says "usable now through station_call", usable_now in JSON): go on with the owner's request in the same turn. Only if the output says RESTART REQUIRED (restart_required: true) did the running engine start without the Station, or for another account; then tell the owner exactly once, after everything else:

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

marketplace is a skill published in the GitHub repository sonichi/sutando (397 stars, last pushed today), licensed MIT. It adds 75 tokens to every session and 1,276 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-09-15.
