va-session

va-session is a skill for Claude Code from jazzenchen/VibeAround. It costs 38 tokens per session (356 once invoked), scanned A, original, MIT.

A small session-identification tool for VibeAround, which coordinates coding-agent sessions. It finds the current session using available environment details and session information.

In plain words
What is it for?
Use it when another VibeAround tool needs the current session ID for session management, handoff, preview, or related coordination work.
Why use it?
Other VibeAround workflows may need the correct session identifier to manage handoffs or continue work. This tool resolves that identifier instead of making the agent guess it.

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.

Security

Grade A, and why

va-session 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 3d 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.

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

VibeAround Session ID

Resolve your current session ID. Other VibeAround skills reference this skill when they need session context for lifecycle management.

How to Resolve

Read these values if available:

  • Current working directory
  • $VIBEAROUND_LAUNCH_ID
  • $VIBEAROUND_PROFILE_ID
  • $VIBEAROUND_CHANNEL_KIND
  • $VIBEAROUND_CHAT_ID

For Claude Code and Claude Desktop, use this rendered value as the current session ID:

${CLAUDE_SESSION_ID}

Call the va_mcp_get_session_id MCP tool. Include only optional arguments whose values are present. If the rendered Claude value is empty or is still the literal placeholder text, omit session_id.

Tool: va_mcp_get_session_id
Server: vibearound
Arguments:
  agent_kind: "claude"
  session_id: "<rendered ${CLAUDE_SESSION_ID} if valid>"
  cwd: "<current working directory>"
  launch_id: "<value of $VIBEAROUND_LAUNCH_ID if present>"
  profile_id: "<value of $VIBEAROUND_PROFILE_ID if present>"
  channel_kind: "<value of $VIBEAROUND_CHANNEL_KIND if present>"
  chat_id: "<value of $VIBEAROUND_CHAT_ID if present>"

Return Value

Return the session ID string from the MCP tool. If the tool cannot resolve one, return nothing — callers handle the missing case gracefully.

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.
