limux-a2a

limux-a2a is a skill for Codex from am-will/limux. It costs 50 tokens per session (2,055 once invoked), scanned A, original, MIT.

A Limux workspace coordination skill for identifying panes, surfaces, and workspaces, then launching and communicating with other agents.

In plain words
What is it for?
It helps create terminal panes or workspaces, start agent tasks, read peer output, coordinate shared surfaces, send callbacks, and notify the user.
Why use it?
It removes the need to manually track where agents are running or how to reach them inside Limux.

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

limux-a2a 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 7d 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.

Limux A2A

Use Limux itself as the live registry. Do not rely on generated files or persistent rosters. Prefer the installed limux command; use ./target/.../limux-cli only when testing this repo build.

Fast Launch

When asked to launch a peer from inside Limux, split first using the already-exported LIMUX_* values. Do not run identify, list-workspaces, or read-screen before the first spawn unless an env value is missing.

created="$(limux --json new-pane \
  --workspace "$LIMUX_WORKSPACE_ID" \
  --pane "$LIMUX_PANE_ID" \
  --surface "$LIMUX_SURFACE_ID" \
  --direction right \
  --command 'claude "Task prompt here. Parent surface if you need it: '"$LIMUX_SURFACE_ID"'."')"

child_surface="$(printf '%s\n' "$created" | jq -r '.surface_ref // .surface_id' | sed 's/^surface://')"
child_pane="$(printf '%s\n' "$created" | jq -r '.pane_ref // .pane_id' | sed 's/^pane://')"

If the fast launch fails with failed to connect to socket, retry that exact new-pane command with approved/escalated socket access. If it fails with Unknown option --json, switch to the repo-built ./target/debug/limux-cli or ./target/release/limux-cli and retry the same command. Only after those retries should you inspect socket/listing state.

Identity

Each Limux terminal should have:

printf 'workspace=%s\npane=%s\nsurface=%s\ntab=%s\nsocket=%s\n' \
  "$LIMUX_WORKSPACE_ID" "$LIMUX_PANE_ID" "$LIMUX_SURFACE_ID" "$LIMUX_TAB_ID" "$LIMUX_SOCKET"

Fallbacks:

limux --json identify
limux --json list-workspaces
limux --json list-panels --workspace "$LIMUX_WORKSPACE_ID"

Target exact peers with --surface <surface-id>. Add --workspace <id-or-name> when the peer is outside the current workspace.

Spawn Panes

Launch tools directly with new-pane --command; do not create an empty shell and later inject a long escaped codex "..." line. Long injected launch lines can wrap or corrupt the shell input.

created="$(limux --json new-pane \
  --workspace "$LIMUX_WORKSPACE_ID" \
  --pane "$LIMUX_PANE_ID" \
  --surface "$LIMUX_SURFACE_ID" \
  --direction right \
  --command 'codex "Task: inspect the diff. Parent surface available if needed: '"$LIMUX_SURFACE_ID"'."')"

child_surface="$(printf '%s\n' "$created" | jq -r '.surface_ref // .surface_id' | sed 's/^surface://')"
child_pane="$(printf '%s\n' "$created" | jq -r '.pane_ref // .pane_id' | sed 's/^pane://')"

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.
