Trajectory bundles
Trajectory capture is OpenClaw’s per-session flight recorder. It records a structured timeline for each agent run, then/export-trajectory packages the
current session into a redacted support bundle.
Use it when you need to answer questions like:
- What prompt, system prompt, and tools were sent to the model?
- Which transcript messages and tool calls led to this answer?
- Did the run time out, abort, compact, or hit a provider error?
- Which model, plugins, skills, and runtime settings were active?
- What usage and prompt-cache metadata did the provider return?
Quick start
Send this in the active session:.openclaw/trajectory-exports/. Absolute
paths and ~ paths are rejected.
Access
Trajectory export is an owner command. The sender must pass the normal command authorization checks and owner checks for the channel.What gets recorded
Trajectory capture is on by default for OpenClaw agent runs. Runtime events include:session.startedtrace.metadatacontext.compiledprompt.submittedmodel.completedtrace.artifactssession.ended
- user messages
- assistant messages
- tool calls
- tool results
- compactions
- model changes
- labels and custom session entries
Bundle files
An exported bundle can contain:| File | Contents |
|---|---|
manifest.json | Bundle schema, source files, event counts, and generated file list |
events.jsonl | Ordered runtime and transcript timeline |
session-branch.json | Redacted active transcript branch and session header |
metadata.json | OpenClaw version, OS/runtime, model, config snapshot, plugins, skills, and prompt metadata |
artifacts.json | Final status, errors, usage, prompt cache, compaction count, assistant text, and tool metadata |
prompts.json | Submitted prompts and selected prompt-building details |
system-prompt.txt | Latest compiled system prompt, when captured |
tools.json | Tool definitions sent to the model, when captured |
manifest.json lists the files present in that bundle. Some files are omitted
when the session did not capture the corresponding runtime data.
Capture location
By default, runtime trajectory events are written beside the session file:OPENCLAW_TRAJECTORY_DIR to store runtime trajectory sidecars in a
dedicated directory:
Disable capture
SetOPENCLAW_TRAJECTORY=0 before starting OpenClaw:
/export-trajectory can still export
the transcript branch, but runtime-only files such as compiled context,
provider artifacts, and prompt metadata may be missing.
Privacy and limits
Trajectory bundles are designed for support and debugging, not public posting. OpenClaw redacts sensitive values before writing export files:- credentials and known secret-like payload fields
- image data
- local state paths
- workspace paths, replaced with
$WORKSPACE_DIR - home directory paths, where detected
- runtime sidecar files: 50 MiB
- session files: 50 MiB
- runtime events: 200,000
- total exported events: 250,000
- individual runtime event lines are truncated above 256 KiB
Troubleshooting
If the export has no runtime events:- confirm OpenClaw was started without
OPENCLAW_TRAJECTORY=0 - check whether
OPENCLAW_TRAJECTORY_DIRpoints to a writable directory - run another message in the session, then export again
- inspect
manifest.jsonforruntimeEventCount
- use a relative name like
bug-1234 - do not pass
/tmp/...or~/... - keep the export inside
.openclaw/trajectory-exports/
