<SUBAGENT-CONTEXT>Skip to Query Mode.</SUBAGENT-CONTEXT>
Skip to Query Mode.
Step 0 (always run first):
0.A — Server beacon check (cross-client; runs on every client including Claude Desktop):
If the tool agentkey_skill_meta is visible in list_tools, call it once with {}. Otherwise skip to 0.B.
The response is structured JSON conforming to protocol/skill-meta-v1. Apply these rules in order:
response.protocol_version !== 1 → only honor update_doc_url; if present, remember it as a fallback for any prompt below.response.skill_version_latest === "" → server admitted it can't tell (offline / rate-limited). Skip to 0.B without prompting.response.skill_version_latest equals this SKILL.md's frontmatter version: field (read it from the top of this file) → up to date. Skip to 0.B.response.update_command / response.update_command_kind / response.update_doc_url. Never call agentkey_skill_meta a second time in the same session.0.B — Inline check (compatibility path for clients with a Bash tool, e.g. Claude Code):
bash "${CLAUDE_PLUGIN_ROOT:-$HOME/.claude}/skills/agentkey/scripts/check-update.sh" 2>/dev/null
The script may print two kinds of lines (in any order):
UP_TO_DATE or empty → continue silently to 0.C.UPGRADE_AVAILABLE <old> <new> → if 0.A already prompted the user this session, skip; else run the legacy Upgrade flow below with the new version, then continue to 0.C.TELEMETRY <event> <key=value> ... → forward via MCP, silently and best-effort:
agentkey_internal({
path: "telemetry/event",
params: { event: "<event>", properties: { /* parsed key=value pairs */ } }
})
If your client has no Bash tool (Claude Desktop, some web-based clients), this step is a no-op — that's fine, 0.A already covered it.
0.C — Verify MCP tools. Confirm list_tools, find_tools, describe_tool, execute_tool are visible. If any are missing → Setup (regardless of what the user asked). Do not attempt Query without all 4. agentkey_account is optional — present on current servers, absent on older deployments; don't gate Setup on it.
Triggered by either:
agentkey_skill_meta returned a skill_version_latest different from this SKILL.md's frontmatter version. Use that response's update_command (when present) instead of the default npx skills update command below. The <old> is this SKILL.md's frontmatter version; <new> is response.skill_version_latest.check-update.sh printed UPGRADE_AVAILABLE <old> <new>. Use <old> and <new> from that line.Below, <old> and <new> refer to whichever pair was resolved above.
Step A — Check for auto-upgrade opt-in. Run:
if [ "${AGENTKEY_AUTO_UPGRADE:-0}" = "1" ] || [ -f "${XDG_CONFIG_HOME:-$HOME/.config}/agentkey/auto-upgrade" ]; then echo AUTO=1; fi
If the output is AUTO=1: tell the user once "Auto-upgrading AgentKey v<old> → v<new>…", run Step C, then continue to step 0.C. Do not show the AskUserQuestion prompt.
Step B — Otherwise, prompt the user.
If a Bash tool is available (Claude Code etc.), use AskUserQuestion. Otherwise (Claude Desktop and any web/sandboxed client without shell access), display the question and four options as a normal chat message and parse the user's natural-language reply.
Important — persistence caveat for no-Bash clients: the Always, Not now, and Never ask again options each persist state by writing a file under ~/.config/agentkey/. Without a Bash tool you cannot write those files. Do not pretend you did — follow the no-Bash fallback line in each option below and tell the user exactly what state did or didn't get saved.
AgentKey v<new> is available (currently on v<old>). Upgrade now?Yes, upgrade now → run Step C.
After running Step C, dispatch (silently, ignore failures):
agentkey_internal({
path: "telemetry/event",
params: { event: "upgrade_decision", properties: {
from_version: "<old>", to_version: "<new>", choice: "accept_once"
}}
})
Always keep me up to date →
mkdir -p "${XDG_CONFIG_HOME:-$HOME/.config}/agentkey" && touch "${XDG_CONFIG_HOME:-$HOME/.config}/agentkey/auto-upgrade". Tell the user "Auto-upgrade enabled — future AgentKey updates install automatically. Remove ~/.config/agentkey/auto-upgrade to undo." Then run Step C.mkdir -p ~/.config/agentkey && touch ~/.config/agentkey/auto-upgrade. For now I'll proceed with this one-time upgrade." Then run Step C.After the action, dispatch (silently, ignore failures):
agentkey_internal({
path: "telemetry/event",
params: { event: "upgrade_decision", properties: {
from_version: "<old>", to_version: "<new>", choice: "accept_always"
}}
})
Not now →
_CFG="${XDG_CONFIG_HOME:-$HOME/.config}/agentkey"
_SNOOZE="$_CFG/update-snoozed"
_NEW="<new>"
_LEVEL=0
if [ -f "$_SNOOZE" ]; then
_SVER=$(awk '{print $1}' "$_SNOOZE" 2>/dev/null)
[ "$_SVER" = "$_NEW" ] && _LEVEL=$(awk '{print $2}' "$_SNOOZE" 2>/dev/null)
case "$_LEVEL" in *[!0-9]*) _LEVEL=0 ;; esac
fi
_LEVEL=$((_LEVEL + 1)); [ "$_LEVEL" -gt 3 ] && _LEVEL=3
mkdir -p "$_CFG" && echo "$_NEW $_LEVEL $(date +%s)" > "$_SNOOZE"
echo "SNOOZED_LEVEL=$_LEVEL"
Translate the level into a duration for the user — SNOOZED_LEVEL=1 → "Next reminder in 24h", 2 → "in 48h", 3 → "in 1 week". Continue to step 0.C — do not upgrade.mkdir -p ~/.config/agentkey && touch ~/.config/agentkey/update-disabled (permanently off — delete that file to re-enable)." Continue to step 0.C — do not upgrade.Map the choice for telemetry: With-Bash uses SNOOZED_LEVEL (1 → snooze_1d, 2 → snooze_2d, 3 → snooze_7d); No-Bash uses snooze_1d (no persisted level). Then dispatch (silently, ignore failures):
agentkey_internal({
path: "telemetry/event",
params: { event: "upgrade_decision", properties: {
from_version: "<old>", to_version: "<new>", choice: "<mapped choice>"
}}
})
Never ask again →
mkdir -p "${XDG_CONFIG_HOME:-$HOME/.config}/agentkey" && touch "${XDG_CONFIG_HOME:-$HOME/.config}/agentkey/update-disabled". Tell the user "Update checks disabled. Remove ~/.config/agentkey/update-disabled to re-enable." Continue to step 0.C — do not upgrade.mkdir -p ~/.config/agentkey && touch ~/.config/agentkey/update-disabled. I'll skip this prompt for the rest of this session." Continue to step 0.C — do not upgrade.After the action, dispatch (silently, ignore failures):
agentkey_internal({
path: "telemetry/event",
params: { event: "upgrade_decision", properties: {
from_version: "<old>", to_version: "<new>", choice: "never_ask"
}}
})
Step C — Run the upgrade.
Branch by trigger:
(A) Server-beacon trigger — response.update_command decides:
update_command_kind === "shell" → Display the command verbatim. If a Bash tool is available, offer to run it for the user; otherwise instruct them to paste it into their terminal.update_command_kind === "manual_ui" (or any unrecognized future kind) → Display response.update_command as instructions only; do not attempt to execute.response.update_command is absent → No automated path exists for this client. Tell the user verbatim, substituting <new> and the actual URL:
AgentKey skill v<new> is available but your client doesn't have an auto-installer. Download the latest release manually from GitHub: <release_notes_url, if response contains one, otherwise https://github.com/chainbase-labs/agentkey/releases/latest\>. Then replace your skill files with the contents of
skills/agentkey/from the release archive and restart your client.
(B) Inline-check trigger (Claude Code with Bash) — run:
npx skills update agentkey
On success: tell the user "✓ AgentKey updated to v<new>." On failure: show the failure verbatim and tell the user "Run npx skills update agentkey manually to retry. If that doesn't work for your client, download from https://github.com/chainbase-labs/agentkey/releases/latest instead." Either way, continue to step 0.C.
After the npx command returns, dispatch (silently, ignore failures):
agentkey_internal({
path: "telemetry/event",
params: { event: "upgrade_result", properties: {
from_version: "<old>", to_version: "<new>",
status: <"ok" if npx succeeded else "fail">,
error_class: <one of "network" | "npx_failed" | "permission" | "unknown" if status=="fail" else null>
}}
})
Decision rules for error_class:
status: "ok", error_class: nullENOTFOUND / ETIMEDOUT / ECONNREFUSED → networkEACCES / permission denied → permissionnpx_failedunknownThen route by intent:
The skill is useless without the AgentKey MCP server registered with the user's agent. Install / re-auth in one shot — run this in the user's shell:
! npx -y @agentkey/cli --auth-login
What it does: opens a browser to mint an API key, then registers the AgentKey MCP server with the user's agent. The skill itself does not write any files; that work is performed by the separate @agentkey/cli package. See SECURITY.md in the repo root for the full list of supported clients and the exact files the CLI touches.
When the command finishes, tell the user verbatim:
✅ MCP installed. Please fully quit and restart your agent so the new tools load. Then re-ask your original question.
Do NOT continue to Query in the same turn — the MCP tools will not exist until the agent restarts.
If the user's agent is Codex / OpenCode / Gemini CLI / Linux Claude Desktop / Hermes / Manus / any other client, --auth-login will not write its config. Guide manual install:
{
"mcpServers": {
"agentkey": {
"type": "http",
"url": "https://api.agentkey.app/v1/mcp",
"headers": { "Authorization": "Bearer ak_..." }
}
}
}
If you don't know the user's agent, ask: "Which agent / client are you using? (Claude Code, Claude Desktop, Cursor, Codex, …)"
list_tools()
If it returns the 4 AgentKey tools → MCP is healthy. Otherwise → route to Setup.

| Tool | Purpose |
|---|---|
list_tools | Browse tool tree by prefix. No prefix → top categories. social → platforms. social/twitter → endpoints |
find_tools | Semantic search. Pass the user's natural-language query (CN / EN / mixed) — don't pre-extract a single keyword. Supports platform aliases: 推特→twitter, 小红书→xiaohongshu, BTC→crypto. |
describe_tool | Get full params + examples + cost (per-call credit price) for any tool name or endpoint path. Required before execute. |
execute_tool | Execute any tool by name + params. All calls go through this. |
agentkey_account | Free — read remaining credit balance + upstream skill health. Use before bulk operations to confirm enough credits. Falls back gracefully when absent on older servers. |
Path A — Progressive (browse by prefix):
list_tools() → top categories
list_tools(prefix="social/xiaohongshu") → xiaohongshu endpoints
describe_tool(name="xiaohongshu/search_notes") → params + execute_as template
execute_tool(name="agentkey_social", params={path: "xiaohongshu/search_notes", params: {keyword: "防晒霜"}})
Path B — Semantic (natural-language query):
Pass the user's full phrasing — including intent verbs like "搜一下" / "抓取" / "news" / "scrape" — not a stripped-down keyword. The router uses both embedding similarity and intent-keyword detection, so the more of the original query reaches the server, the better the routing.
find_tools(q="帮我在小红书上搜防晒霜的笔记") → matched endpoints with scores
describe_tool(name="xiaohongshu/search_notes") → params + execute_as template
execute_tool(name="agentkey_social", params={path: "xiaohongshu/search_notes", params: {keyword: "防晒霜"}})
Web search:
execute_tool(name="agentkey_search", params={query: "AI news", type: "news", num: 5})
Scrape a URL:
execute_tool(name="agentkey_scrape", params={url: "https://example.com"})
Crypto prices:
execute_tool(name="agentkey_crypto", params={type: "market/quotes", params: {symbol: "BTC"}})
For social/crypto with many endpoints, always discover first:
list_tools(prefix="social/twitter") → see endpoints
describe_tool(name="twitter/web/fetch_trending") → get params
execute_tool(name="agentkey_social", params={path: "twitter/web/fetch_trending", params: {}})
Try first, guide if needed. Never ask about API keys before executing.
| Error | Action |
|---|---|
Authentication failed | "API key invalid. Get a new one at https://console.agentkey.app/" |
Insufficient credits | "Credits exhausted. Top up at https://console.agentkey.app/" |
Rate limited | "Rate limited. Wait a moment and try again." |
not_found | Report to user. Do NOT retry with guessed IDs. |
| Missing required param | Fix params using the suggestion field and retry once. |
Never expose raw error details to user.
