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.

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 | $0.00099 | $0.01736 |
| Opus 5.5 | $0.00040 | $0.00694 |
| Sonnet 5.5 | $0.00020 | $0.00347 |
| Haiku 4.5 | $0.00010 | $0.00174 |
Grade B, and why
using-alpacon 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 2d 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.

Using Alpacon
Alpacon is reached only through its MCP tools. Clients name them differently (list_servers may appear behind a prefix such as mcp__alpacon__ or mcp__plugin_alpacon_alpacon__); this skill uses the bare tool names. When a call fails on a read or a connection error, report the exact error, try another Alpacon tool that answers the same question, or ask the person for the missing sign-in or permission. A refusal or a pending_approval result is not such a failure: follow the sections below, and never move the same work to another tool to get past it. Never fall back to the alpacon CLI, ssh, or another shell route.
Find the workspace and server
- Call
list_workspacesand use a workspace name exactly as it returns it. Passregion(ap1orus1) only when the same workspace appears in both. - Call
list_serversand take the server'sid. Everyserver_idandserversargument is a UUID; a server name is refused before the request is sent. The list is paginated, so follownextwhencountis larger than the page.
Read every result before the next call
- Branch on
status, not on prose:success,error,pending_approval,purpose_required, andmfa_requiredare the common values. For any other value, readmessageandnext_action. - When a result carries
next_action, do what it says.requires_human_approval: truemeans a person decides;approvable_by_agent: falsemeans no tool of yours can. - A command result can say
successand still carrysudo_denialorsudo_hint: the sudo inside it did not run. Withsudo_denial, a person can resolve it; rerun the command after they act, knowing the whole line runs again. Withsudo_hintalone, it is a hard denial: do not wait for it and do not rerun it unchanged. - A refusal carrying
rejection_cause,gate, ormissingis not cleared by resending it unchanged. Follow its hint: some ask you to fix the call, some to wait for a person's decision or MFA, after which the same call can succeed.
What ships with it
7 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.
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.

using-alpacon is a skill published in the GitHub repository alpacax/alpacon-mcp (1 stars, last pushed yesterday), licensed MIT. It adds 99 tokens to every session and 1,736 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-31.
