The previous /rlm slash command flow had a UI rendering gap (the answer
never made it back to the model's view) and required the user to invoke
it manually. Pivoting to a tool-call surface and aligning the in-REPL
helpers with the canonical reference (alexzhang13/rlm) by the paper
authors so the same prompts and decomposition patterns transfer.
New tool: rlm_process
- crates/tui/src/tools/rlm_process.rs
- Inputs: task (small, shown to root LLM each iter as root_prompt) +
exactly one of file_path (workspace-relative, preferred) or content
(inline, capped at 200k chars). Optional child_model and max_depth.
- Loaded across Plan/Agent/YOLO; never deferred via ToolSearch.
- Returns the final answer string + metadata (iterations, duration,
tokens, termination).
REPL surface aligned with reference (alexzhang13/rlm):
- Variable name `context` (was PROMPT)
- Code fence ```repl (was ```python; python/py kept as fallback)
- Helpers: llm_query, llm_query_batched (NEW), rlm_query (was sub_rlm),
rlm_query_batched (NEW), SHOW_VARS (NEW), FINAL, FINAL_VAR,
repl_get/repl_set
- Top-level JSON-serializable user variables auto-persist across rounds
(no repl_set ceremony required)
- FINAL(...) / FINAL_VAR(...) parseable from the model's raw response
text (parse_text_final), in addition to the in-REPL sentinel path.
Code-fenced occurrences are correctly ignored to prevent false hits.
Sidecar (axum, 127.0.0.1:0):
- Added POST /llm_batch and POST /rlm_batch endpoints (parallel fanout,
cap 16 prompts per batch). Mirrors the reference's batched semantics.
Other:
- System prompt rewritten with reference's strategy patterns
(PREVIEW → CHUNK+map-reduce via llm_query_batched → RECURSIVE
decomposition via rlm_query → programmatic compute + LLM interp).
- Strict termination loop unchanged: must emit ```repl or text-level
FINAL each round; one fence-less round → reminder, two → DirectAnswer.
- /rlm slash command remains for manual debug; description points the
model toward rlm_process for the in-agent flow.
