Summary

A user reported this issue

[11:48 AM]Jordan Christensen I've been running claude as a CLI tool in a ralph loop, and either it doesn't generate traces, or you can't see them. Anything I can do to help there?
[11:50 AM]Tarun Sachdeva does ralph loop use the claude code sdk
[11:50 AM]i don't really know how it works tbh
[11:52 AM]we look for things in the .claude directory, and if ralp stores them elsewhere we might not find them
[11:52 AM]Jordan Christensen I'm using this one https://github.com/thebigjc/portableralph - it was a little buggy, so I have a PR up with a fix, but this version works for me. It runs claude -p which is:
-p, --print Print response and exit (useful for pipes). Note: The workspace trust dialog is skipped when Claude is run with
the -p mode. Only use this flag in directories you trust.and:
--output-format <format> Output format (only works with --print): "text" (default), "json" (single result), or "stream-json" (realtime
streaming) (choices: "text", "json", "stream-json")(stream-json is what I enabled because it looked like it was just sitting there)
[11:52 AM]it's possible it doesn't write to .claude when you run it that way?
[11:53 AM]Tarun Sachdeva ohhhh yeah that's probably it
[11:53 AM]great great find thank you
[11:53 AM]i'll add a ticket and push an update tonight
[11:53 AM]feels easy enough to fix
[11:55 AM]Jordan Christensen I'm not sure where else it's writing to, so I hope there is something you can harvest
[11:55 AM]Tarun Sachdeva the thing is, if its running claude, claude should find them
[11:56 AM]i see some of your traces with ralph loop messages, we have to parse those out on the frontend for readability
[11:57 AM]Jordan Christensen Interesting. I ran like 30 iterations over night and I see no additional traces.
[11:57 AM]Tarun Sachdeva you're saying you're not seeing them in the TUI at all
[11:57 AM]interesting
[11:57 AM]Jordan Christensen image.png [11:57 AM]I was going to bug you for a 'upload all the things' button if they were all there
[11:58 AM]but none were[11:58 AM]

They use ralph, https://github.com/snarktank/ralph

and https://github.com/thebigjc/portableralph

please go throuhg our adapter code and check out whats going on, for some reason their ralph loops aren't visible on traces tui

Found Root Cause in Adapter

What Was Wrong

Adapter availability gated on history.jsonl, but claude -p writes sessions without reliably updating history.
Early return in trace retrieval prioritized history presence, ignoring project updates.
Cursor keyed only to history caused stale state when projects changed but history did not.

What I Changed

Removed strict gating on history presence to allow adapter availability with project sessions alone.
Updated trace retrieval to merge project session summaries even if history is stale.
Revised cursor logic to track project directory changes for accurate state detection.
Changes implemented in adapter code at:
- availability check (v1.ts:116)
- trace retrieval starting at line 124
- project session summaries at line 520
- cursor comparison between lines 186–195
- project cursor state at line 669
Added tests at adapters.test.ts lines 1150 and 1407 covering these fixes.

Validation

Ran bun test test/core/adapters.test.ts and targeted tests with -t "claude-code:"; all passed.
bun run typecheck showed existing repo-wide errors unrelated to these changes.
Inspected external Ralph scripts confirming use of claude --print, consistent with found behavior.

Next

Recommend running the updated adapter with Ralph loop to verify fix in environment.
Consider adding telemetry for cases with zero-history but present project sessions.
Potential future support for stream-json logs (claude -p --output-format stream-json) as history updates may not align.

Root Cause

I traced this to the Claude adapter being too history.jsonl-centric for ralph/portableralph usage (claude --print, often with --output-format stream-json).
isAvailable() required history.jsonl, so sessions written under projects-only storage were treated as “adapter unavailable” (cli/src/adapters/claude-code/v1.ts:116).
getTraces() returned history-backed traces first and did not surface project-only sessions when history existed but was stale (cli/src/adapters/claude-code/v1.ts:124).
getTraceIndexBatch() cursor invalidation only watched history mtime/size, so project-side changes could be skipped forever (cli/src/adapters/claude-code/v1.ts:186).

Fix Implemented

Made Claude adapter available when either history or projects storage exists (cli/src/adapters/claude-code/v1.ts:116).
Reworked discovery to merge:
- history summaries, plus
- bounded supplemental scan of project session files (recent-first by mtime), skipping IDs already in history (cli/src/adapters/claude-code/v1.ts:124, cli/src/adapters/claude-code/v1.ts:520).
Extended discovery cursor to include project-tree state (projectsMtimeMs, projectDirCount) so non-history updates trigger re-index (cli/src/adapters/claude-code/v1.ts:65, cli/src/adapters/claude-code/v1.ts:659).
Added regression tests for:
- projects-only discovery with missing history (cli/test/core/adapters.test.ts:1150)
- cursor refresh when projects change without history updates (cli/test/core/adapters.test.ts:1407).

Validation

Ran bun test test/core/adapters.test.ts in cli/ → passing (116 pass).
Re-ran focused Claude tests bun test test/core/adapters.test.ts -t "claude-code:" → passing (12 pass).

If you want, I can also add a tiny debug/status surfacing in traces status to explicitly show “history stale, using project fallback” so these cases are easier to diagnose in production.

also btw Session and Memory Storage
The Ralph loop is designed to "forget on purpose" to avoid context bloat. Instead of relying on a long-running internal session, it externalizes state to the filesystem:
Local Project Files: Progress is stored in your project directory using a prd.json (task list) and progress.txt (append-only log of learnings).
Git History: The loop typically makes a Git commit after every successful task, using the commit history as the permanent "memory" of the project's evolution.
CLI Session Cache: The underlying Claude Code CLI may store session IDs and local caches in your home directory (e.g., ~/.claude/tasks/) for up to 30 days to enable manual session resumption.
Docker Sandboxes: If running via Docker Desktop, state and credentials are often isolated within Docker volumes associated with that specific sandbox instance.
Would you like the Bash script template used to set up a manual Ralph loop on your local machine?
