focus

focus is a skill for Claude Code from spacegrowth/claude-relay. It costs 56 tokens per session (292 once invoked), scanned A, original, MIT.

A session-control command that selects an executor's or lead's tab in iTerm, the macOS terminal application. It uses the session identifier to find the matching tab.

In plain words
What is it for?
Use it to switch to a session, executor, or lead; if an executor's tab is gone, use the suggested resume or restart action.
Why use it?
It saves you from manually searching through terminal tabs when you need to inspect or continue a particular coding-agent session.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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

focus 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 6d 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

Run: ${CLAUDE_PLUGIN_ROOT}/bin/relay focus $session_id (Claude Code substitutes the plugin's absolute path when this skill loads — call it this way, not as bare relay, which often isn't on the Bash tool's non-interactive PATH).

This activates iTerm and selects the session's tab whose title matches its relay label (a bounded match tolerant of Claude Code's title suffix), then selects that tab's window and the tab — the reliable osascript mechanism from claude-sessions-swiftbar. Works for executors AND leads: both get a stable relay-controlled tab title (executors at spawn, leads when /relay:mode renames their tab), so pass either kind of session id. If an executor's tab is closed, relay points you to /relay:resume (keeps context) or /relay:restart (re-runs the packet); if a lead's tab can't be matched, re-running /relay:mode in that lead resets its title.

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.
