A local command-line bridge for passing messages between Claude Code and Codex sessions. It can control sessions through tmux or connect to a Claude daemon over a Unix socket.

Starting, asking questions in, and stopping Claude or Codex sessions; relaying work between them; and connecting to a local Claude daemon.

It removes the need to switch between separate agent sessions or relay messages manually. It also falls back to tmux when the preferred connection is unavailable.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add tellang/triflux --skill tfx-live

Clone the repo

git clone --depth 1 https://github.com/tellang/triflux

Made for: Claude Code, Codex.

Or install triflux, the plugin that ships this one along with the rest of its 29 skills, 1 agent, 12 hooks.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00053	$0.01408
Opus 5	$0.00026	$0.00704
Sonnet 5	$0.00011	$0.00282
Haiku 4.5	$0.00005	$0.00141

Security

Grade A, and why

tfx-live 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 9d 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.

tfx-live — Claude↔Codex live orchestration

tfx-live is the Triflux-owned live bridge for Claude Code and Codex TUI sessions. It runs as a local CLI (tfx-live) and supports tmux TUI control plus Claude daemon UDS attach.

Default transport

Claude targets with --short or --session-id: UDS-first auto by default.
If UDS probe/attach fails: write ~/.claude/cache/triflux/tfx-live/bug-reports/uds-fallback-*.json, then tmux fallback when --session is provided.
Codex targets and Claude targets without a daemon ref: tmux by default.
UDS completion contract: done=true only when matchedCompletion===true; timedOut or closed is not completion.
Bridge resolution: --bridge > $TFX_BRIDGE > $TFX_REPO_ROOT/hub/bridge.mjs > bundled Triflux hub/bridge.mjs.

Quick start

# Claude -> Codex helper session
tfx-live start --cli codex --session cx1 --cwd ~/Projects
tfx-live ask --cli codex --session cx1 --prompt "현재 변경사항을 요약해줘" --timeout 120
tfx-live stop --cli codex --session cx1

# Codex -> Claude tmux helper session
tfx-live start --cli claude --session cl1 --cwd ~/Projects
tfx-live ask --cli claude --session cl1 --prompt "이 구현을 리뷰해줘" --timeout 120
tfx-live stop --cli claude --session cl1

UDS-first Claude daemon ask

Find daemon sessions:

tfx-live probe

Then ask by short:

tfx-live ask --cli claude --short <8hex> --prompt "STRUCTURED_RETURN_OK 만 답해줘" --timeout 120

Because --short is present, the default transport is auto: probe UDS first, then tmux fallback only if --session is also provided. For explicit UDS-only failure behavior:

tfx-live ask --cli claude --transport uds --short <8hex> --prompt "..." --timeout 120

Codex tmux session discovery

List the Codex CLI sessions already running in tmux; this does not require a prior tfx-live start. The JSON result includes the tmux session name, start time, current working directory, and attachment state.

# All locally running Codex tmux sessions
tfx-live list-sessions --cli codex

# Limit discovery to sessions whose pane cwd exactly matches this worktree
tfx-live list-sessions --cli codex --cwd ~/Projects/my-worktree

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.

tfx-live is a skill published in the GitHub repository tellang/triflux (7 stars, last pushed yesterday), licensed MIT. It adds 53 tokens to every session and 1,408 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.

Set two agent sessions talking through the Luciazero Agent Bus and watch it live in a terminal: pick the pair, open the windows, read the transcript. Use for "ให้ codex กับ claude คุยกัน" or "watch the bus".

Make an unfamiliar repository agent-ready with a verify command, smoke tests, guardrails, and project notes. Use for repository setup, agentic engineering, verify commands, hooks, or allowlists; skip when verification and scope are already clear.

handoff

Write a state capsule so the next session — or a different agent/harness — can resume unfinished work without re-deriving context. Use when a session is ending with work incomplete, when the user says "handoff", "pack up", "ส่งต่อ", "continue tomorrow", when switching between Claude Code and Codex mid-task, or when…
