smoke

smoke is a skill for Claude Code, Codex from okisdev/claude-code-fusion. It costs 25 tokens per session (468 once invoked), scanned A, original, MIT.

A live smoke test for a plugin update. It runs three small checks through the Codex, Grok, and Fusion dispatch paths, where dispatch means sending work to the intended worker, and reports whether the chain is healthy.

In plain words
What is it for?
Use it after updating the plugins to compare installed versions, test Codex, Grok, and Fusion workers, and record whether each probe passed.
Why use it?
It catches version mismatches or broken routing before real packages depend on the update. Exact response markers make it clear whether each probe completed correctly.

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

smoke 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

Verify the update landed, then prove the dispatch chain end to end with three tiny probes before real packages ride it.

  1. Version parity: read ~/.claude/plugins/installed_plugins.json and compare the fusion, codex, and grok entries against .claude-plugin/marketplace.json in this repository when present. Report each version pair; a mismatch is a FAIL naming the stale plugin.
  2. Fan out three probes as parallel foreground Agent calls in one message: a codex:codex-rescue task passing --model gpt-5.6-luna --effort low -- Reply with exactly this single line and nothing else: FUSION-SMOKE-CODEX-OK; a grok:grok-rescue task whose direct prompt passes --effort low -- followed by a brief whose header line is grok-role: burst | effort low | acceptance: exact marker line and whose body asks for exactly the line FUSION-SMOKE-GROK-OK; a fusion:trivial-worker brief in the fusion-brief: v1 envelope with context-mode: isolated, a goal of returning exactly the line FUSION-SMOKE-WORKER-OK, a scope of no file access, and an acceptance of the exact marker line.
  3. Collect all three, then settle them in one /fusion:stats --record call with one pair per probe: accepted only when the exact marker line came back, rejected otherwise.
  4. Report one PASS or FAIL line per gate: version parity, codex dispatch and envelope, grok dispatch and sandbox handshake, worker dispatch and deliverable, settlement write. A FAIL names the failing surface and advises holding real dispatches on that lane until repaired.

The wave is a probe, not work: never attach real packages to it, and never skip the settlement step, because the settlement write is itself one of the gates under test.

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.

smoke is a skill published in the GitHub repository okisdev/claude-code-fusion (3 stars, last pushed 16d ago), licensed MIT. It adds 25 tokens to every session and 468 once invoked, about $0.0001 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.
