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 covering:
For a broad Gateway support report, start with
/diagnostics instead; it collects the
sanitized Gateway bundle and, for OpenAI Codex harness sessions, can send Codex
feedback to OpenAI after approval. Use /export-trajectory when you need the
detailed per-session prompt, tool, and transcript timeline.
Send in the active session (alias /trajectory):
/export-trajectory
OpenClaw writes the bundle under the workspace:
.openclaw/trajectory-exports/openclaw-trajectory-<session>-<timestamp>/
Pass a relative output directory name to override it:
/export-trajectory bug-1234
The name resolves inside .openclaw/trajectory-exports/. Absolute paths and
~ paths are rejected.
Trajectory bundles can contain prompts, model messages, tool schemas, tool results, runtime events, and local paths, so the chat command always runs through exec approval. Approve the export once when you intend to create the bundle; do not use allow-all. In group chats, OpenClaw sends the approval prompt and export result to the owner privately instead of posting trajectory details back to the shared room.
For local inspection or support workflows, run the underlying CLI command directly:
openclaw sessions export-trajectory --session-key "agent:main:telegram:direct:123" --workspace .
Other flags: --output <path> (directory name inside
.openclaw/trajectory-exports), --store <path> (session store override),
--agent <id> (agent id for store resolution), --json (structured output).
Trajectory export is an owner command. The sender must pass the normal command authorization checks plus the owner check for the channel.
Trajectory capture is on by default for OpenClaw agent runs.
Runtime events include:
session.startedtrace.metadatacontext.compiledprompt.submittedmodel.fallback_step, including the source model, next model, failure reason/detail, chain position, and whether the chain advanced, succeeded, or was exhaustedmodel.completedtrace.artifactssession.endedTranscript events are reconstructed from the active session branch: user messages, assistant messages, tool calls, tool results, compactions, model changes, labels, and custom session entries.
Events are written as JSON Lines with this schema marker:
{
"traceSchema": "openclaw-trajectory",
"schemaVersion": 1
}
| 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 a given bundle; some files are
omitted when the session did not capture the corresponding runtime data.
By default, runtime trajectory events are written beside the session file:
<session>.trajectory.jsonl
OpenClaw also writes a best-effort pointer file beside the session:
<session>.trajectory-path.json
Set OPENCLAW_TRAJECTORY_DIR to store runtime trajectory sidecars in a
dedicated directory instead, one JSONL file per session id:
export OPENCLAW_TRAJECTORY_DIR=/var/lib/openclaw/trajectories
Session maintenance removes trajectory sidecars when their owning session entry is pruned, capped, or evicted by the sessions disk budget. Runtime files outside the sessions directory are removed only when the pointer target still proves it belongs to that session.
export OPENCLAW_TRAJECTORY=0
This disables runtime trajectory capture 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.
OpenClaw flushes runtime trajectory sidecars during agent cleanup. The default
cleanup timeout is 10,000 ms. On slow disks or large stores, set
OPENCLAW_TRAJECTORY_FLUSH_TIMEOUT_MS before starting OpenClaw:
export OPENCLAW_TRAJECTORY_FLUSH_TIMEOUT_MS=30000
This controls when OpenClaw logs an openclaw-trajectory-flush timeout and
continues; it does not change the trajectory size caps. To tune all agent
cleanup steps that do not pass an explicit timeout, set
OPENCLAW_AGENT_CLEANUP_TIMEOUT_MS.
Trajectory bundles are for support and debugging, not public posting. OpenClaw redacts sensitive values before writing export files:
$WORKSPACE_DIRThe exporter also bounds input size:
Review bundles before sharing them outside your team. Redaction is best-effort and cannot know every application-specific secret.
If the export has no runtime events:
OPENCLAW_TRAJECTORY=0OPENCLAW_TRAJECTORY_DIR points to a writable directorymanifest.json for runtimeEventCountIf the command rejects the output path:
bug-1234/tmp/... or ~/....openclaw/trajectory-exports/If the export fails with a size error, the session or sidecar exceeded the export safety limits above. Start a new session or export a smaller reproduction.
