# Gist the session
Run `session-logger` to export a Claude Code session to markdown format and share as a private GitHub gist.
## Usage
- The current transcript path should be obvious from context when the `session-logger --hook` `SessionStart` hook is enabled
- If the transcript path is not present, the user may need to add or fix their hook configuration
- `session-logger` takes a `--description` option that will be used as the description for the resulting gist
## Examples
``` bash
session-logger --gist --description "Setting up PostgreSQL" ~/.claude/projects/<project>/<session>.jsonl
</details>

● To set up session-logger for Claude Code:
1. **Add the SessionStart hook** to `~/.claude/settings.json`:
```json
"hooks": {
"SessionStart": [
{
"matcher": "*",
"hooks": [
{
"type": "command",
"command": "session-logger --hook"
}
]
}
]
}
- Add the slash command by creating a file in
~/.claude/commands/with the content shown above from--install-command
The hook will automatically track session info, and you can use session-logger --gist to export sessions as GitHub gists.
● what does the claude slash command look like?

● I found the issue. The content variable is correctly a string when read from the file, but line 738 calls extract_session_id_from_jsonl(content) after content has been processed into messages. The function should receive the original string content, not the processed messages. Let me fix this:

● args.filename comes from the positional argument defined on line 579. The issue is that the variable content gets reused. Let me trace the flow more carefully:
- Line 599:
content = f.read()(string) - Line 605:
for line in content.strip().split("\n"):(still string) - Line 738:
session_id = extract_session_id_from_jsonl(content)(still should be string)
The error suggests content is a list. Let me check if there's another assignment to content after line 601:
Grep(content =)

927- self.assertEqual(format_code_block(content, "python"), expected)
● I can see the problem! After line 601, the content variable is never reassigned as a list. The issue is that extract_session_id_from_jsonl() is being called with the wrong variable. Looking at the function, it expects the raw JSONL content string, but at line 738, content is still the string.
Let me check the actual error more carefully - the error says 'list' object has no attribute 'strip', which means content is somehow a list when passed to extract_session_id_from_jsonl().
Wait, let me check if there's a variable name collision or if content gets overwritten somewhere between lines 601 and 738.
● ok, go ahead and make the proposed fix
