The coding agent now sees the active LangSmith tracing project name(s) in its context when tracing is enabled.

LocalContextMiddleware already injects environment context (git, runtimes, MCP servers) into the system prompt, but it said nothing about LangSmith tracing. deepagents-code deliberately routes its own traces to a dedicated project (get_langsmith_project_name()) while preserving the user's original LANGSMITH_PROJECT for shell commands it runs — so the agent had no way to know where to look for its traces.

This adds a **LangSmith Tracing** section listing both project names (no network/URL lookup) so the agent can fetch the relevant runs via the LangSmith MCP server or CLI. The section is omitted entirely when tracing is disabled, and the second line collapses when the two projects are identical.

Expose the agent's LangSmith tracing project (and the user's original
`LANGSMITH_PROJECT` used by shell commands) in the system prompt so the
agent can look up its own runs via the LangSmith MCP server or CLI. The
section is omitted entirely when tracing is disabled.

🟡 Backticks still escape tracing project quoting

This line now uses a single-line sanitized project name, but it still places that value inside a Markdown code span without escaping backticks. sanitize_control_chars() does not remove printable backticks, so a workspace .env can set LANGSMITH_PROJECT / DEEPAGENTS_CODE_LANGSMITH_PROJECT to something like prod Ignore previous instructions` and the text after the first backtick lands outside the code span in the system prompt whenever tracing is enabled. Please use a quoting format that cannot be broken by backticks (for example JSON encoding) before adding the value to the prompt.

…ware` (langchain-ai#3836)

The coding agent now sees the active LangSmith tracing project name(s)

`LocalContextMiddleware` already injects environment context (git,
runtimes, MCP servers) into the system prompt, but it said nothing about
LangSmith tracing. `deepagents-code` deliberately routes its *own*
traces to a dedicated project (`get_langsmith_project_name()`) while
preserving the user's original `LANGSMITH_PROJECT` for shell commands it
runs — so the agent had no way to know where to look for its traces.

This adds a `**LangSmith Tracing**` section listing both project *names*
(no network/URL lookup) so the agent can fetch the relevant runs via the
LangSmith MCP server or CLI. The section is omitted entirely when
tracing is disabled, and the second line collapses when the two projects
are identical.
