Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00056 | $0.00292 |
| Opus 5 | $0.00028 | $0.00146 |
| Sonnet 5 | $0.00011 | $0.00058 |
| Haiku 4.5 | $0.00006 | $0.00029 |
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.

focus is a skill published in the GitHub repository spacegrowth/claude-relay (1 stars, last pushed yesterday), licensed MIT. It adds 56 tokens to every session and 292 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

review-team
A multi-reviewer code review process that checks a change from several specialist viewpoints and combines the results into one report. It can cover bugs, security, tests, dependencies, frontend behavior, and continuous-integration workflows.
ultra
Fans the work out as a fleet of parallel Grok and Codex agents billed to their own subscriptions, then synthesizes one result. The peer engine equivalent of ultracode, adding intensity without spending Claude quota on the fleet. Use it for genuinely broad goals, not only explicit asks for intensity.

Convenes a blind Codex and Grok panel on one neutral brief and adjudicates the verdicts.

Brief writing guidance for composing self contained Grok briefs for coding, review, diagnosis, and second opinion tasks.
grok-result-handling
Internal guidance for presenting Grok companion output back to the user.

Runs a three probe live smoke wave after a plugin update and reports gate chain health before real work rides it.
