Commands for moving Codex conversations into and out of dsh-codex-sync, a session-sync tool. They also control which sessions and related settings are included.

Use them to preview or import selected Codex chats, import all chats, attach workspaces, export chats, change sync settings, and check service health.

They help preview imports, avoid importing unwanted sub-agent sessions, and repeat imports safely without duplicating conversations. They also provide checks for the sync service and its connection to MCP.

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.

Made for: Claude Code, Codex.

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	$0.00040	$0.00936
Opus 5	$0.00020	$0.00468
Sonnet 5	$0.00008	$0.00187
Haiku 4.5	$0.00004	$0.00094

Security

Grade B, and why

codex-sync scanned grade B with 1 finding 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 2d 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.

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

- `mcpMirror` — auto-mirror `[mcp_servers.*]` from `~/.codex/config.toml` (takes effect after DSH restart).

Codex sync (this plugin)

You can drive dsh-codex-sync with slash commands. Prefer a dry-run before writing sessions.

Import Codex conversations

/import-codex --dry-run
/import-codex
/import-codex --include-subagents
/import-codex --ids codex-abc,codex-def
/import-codex --limit 20 --project my-app --since 2026-08-01
/import-all
/attach-workspaces

The composer Import from Codex button opens a picker: projects → chats, sub-agents nested under the parent thread, already-imported rows greyed out. Prefer that UI when the user is in the web app.

--dry-run prints [would-import] lines and writes nothing.
Default import skips Codex sub-agent threads (parent_thread_id). Add --include-subagents only if the user wants those too.
Already-imported ids are skipped (idempotent). Huge rollouts above maxSessionBytes are skipped.

Composer Sync ▾ → Import from Codex opens the picker. After a successful import the page reloads in ~2.5s so new chats appear.

Export DSH chats to Codex

Writes new Codex rollouts (new uuid, text only — not a resume of the original thread; every export creates a new copy and never overwrites original):

/export-codex --dry-run
/export-codex --ids sess-1,sess-2

Composer Sync ▾ → Export to Codex opens the picker over DSH sessions:

Filters: "From Codex" (showCodex, default off) and "Hide sub-agents" (hideSub, default on) filter toggles.
Codex-origin sessions: Only DSH-updated chats (dshUpdated=true, tagged "Updated in DSH" / "DSH 已续聊") are selectable. Unchanged or source-missing chats remain locked.
Sub-agents: Hidden by default and nested under parent sessions for organization. Selecting a child sub-agent exports it as a separate independent thread (not merged with parent).
Export copies: Exporting creates brand-new Codex rollouts and thread entries; original Codex conversations are never overwritten.

Settings (persisted in `~/.dsh/codex-sync.json`)

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.

codex-sync is a skill published in the GitHub repository Walvez/dsh-codex-sync (25 stars, last pushed 6d ago), licensed MIT. It adds 40 tokens to every session and 936 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
