|
|

./scripts/ralph-loop-codex.sh --rlm ./rlm/context.txt
|
|
|
|
Modes:
|
|
build (default) Pick incomplete spec and implement
|
|
plan Create IMPLEMENTATION_PLAN.md (OPTIONAL)
|
|
|
|
Work Source:
|
|
Agent reads specs/*.md and picks the highest priority incomplete spec.
|
|
|
|
YOLO Mode: Uses --dangerously-bypass-approvals-and-sandbox
|
|
|
|
RLM Mode (optional):
|
|
--rlm-context <file> Treat a large context file as external environment.
|
|
The agent should read slices instead of loading it all.
|
|
--rlm [file] Shortcut for --rlm-context (defaults to rlm/context.txt)
|
|
|
|
RLM workspace (when enabled):
|
|
- rlm/trace/ Prompt snapshots + outputs per iteration
|
|
- rlm/index.tsv Index of all iterations (timestamp, prompt, log, status)
|
|
- rlm/queries/ and rlm/answers/ For optional recursive sub-queries

# Ralph Build Mode
|
|
|
|
Based on Geoffrey Huntley's Ralph Wiggum methodology.
|
|
|
|
---
|
|
|
|
## Phase 0: Orient
|
|
|
|
Read `.specify/memory/constitution.md` to understand project principles and constraints.
|
|
|
|
---
|
|
|
|
## Phase 1: Discover Work Items
|
|
|
|
Search for incomplete work from these sources (in order):
|
|
|
|
1. **specs/ folder** — Look for `.md` files NOT marked `## Status: COMPLETE`
|
|
2. **IMPLEMENTATION_PLAN.md** — If exists, find unchecked `- [ ]` tasks
|
|
3. **GitHub Issues** — Check for open issues (if this is a GitHub repo)
|
|
4. **Any task tracker** — Jira, Linear, etc. if configured
|
|
|
|
Pick the **HIGHEST PRIORITY** incomplete item:
|
|
- Lower numbers = higher priority (001 before 010)
|
|
- `[HIGH]` before `[MEDIUM]` before `[LOW]`
|
|
- Bugs/blockers before features
|
|
|
|
Before implementing, search the codebase to verify it's not already done.
|
|
|
|
---
|
|
|
|
## Phase 1b: Re-Verification Mode (No Incomplete Work Found)
|
|
|
|
**If ALL specs appear complete**, don't just exit — do a quality check:
|
|
|
|
1. **Randomly pick** one completed spec from `specs/`
|
|
2. **Strictly re-verify** ALL its acceptance criteria:
|
|
- Run the actual tests mentioned in the spec
|
|
- Manually verify each criterion is truly met
|
|
- Check edge cases
|
|
- Look for regressions
|
|
3. **If any criterion fails**: Unmark the spec as complete and fix it
|
|
4. **If all pass**: Output `<promise>DONE</promise>` to confirm quality
|
|
|
|
This ensures the codebase stays healthy even when "nothing to do."
|
|
|
|
---
|
|
|
|
## Phase 2: Implement
|
|
|
|
Implement the selected spec/task completely:
|
|
- Follow the spec's requirements exactly
|
|
- Write clean, maintainable code
|
|
- Add tests as needed
|
|
|
|
---
|
|
|
|
## Phase 3: Validate
|
|
|
|
Run the project's test suite and verify:
|
|
- All tests pass
|
|
- No lint errors
|
|
- The spec's acceptance criteria are 100% met
|
|
|
|
---
|
|
|
|
## Phase 4: Commit & Update
|
|
|
|
1. Mark the spec/task as complete (add `## Status: COMPLETE` to spec file)
|
|
2. `git add -A`
|
|
3. `git commit` with a descriptive message
|
|
4. `git push`
|
|
|
|
---
|
|
|
|
## Completion Signal
|
|
|
|
**CRITICAL:** Only output the magic phrase when the work is 100% complete.
|
|
|
|
Check:
|
|
- [ ] Implementation matches all requirements
|
|
- [ ] All tests pass
|
|
- [ ] All acceptance criteria verified
|
|
- [ ] Changes committed and pushed
|
|
- [ ] Spec marked as complete
|
|
|
|
**If ALL checks pass, output:** `<promise>DONE</promise>`
|
|
|
|
**If ANY check fails:** Fix the issue and try again. Do NOT output the magic phrase.

# Ralph Planning Mode (OPTIONAL)
|
|
|
|
This mode is OPTIONAL. Most projects work fine directly from specs.
|
|
|
|
Only use this when you want a detailed breakdown of specs into smaller tasks.
|
|
|
|
---
|
|
|
|
## Phase 0: Orient
|
|
|
|
0a. Read `.specify/memory/constitution.md` for project principles.
|
|
|
|
0b. Study `specs/` to learn all feature specifications.
|
|
|
|
---
|
|
|
|
## Phase 1: Gap Analysis
|
|
|
|
Compare specs against current codebase:
|
|
- What's fully implemented?
|
|
- What's partially done?
|
|
- What's not started?
|
|
- What has issues or bugs?
|
|
|
|
---
|
|
|
|
## Phase 2: Create Plan
|
|
|
|
Create `IMPLEMENTATION_PLAN.md` with a prioritized task list:
|
|
|
|
```markdown
|
|
# Implementation Plan
|
|
|
|
> Auto-generated breakdown of specs into tasks.
|
|
> Delete this file to return to working directly from specs.
|
|
|
|
## Priority Tasks
|
|
|
|
- [ ] [HIGH] Task description - from spec NNN
|
|
- [ ] [HIGH] Task description - from spec NNN
|
|
- [ ] [MEDIUM] Task description
|
|
- [ ] [LOW] Task description
|
|
|
|
## Completed
|
|
|
|
- [x] Completed task
|
|
```
|
|
|
|
Prioritize by:
|
|
1. Dependencies (do prerequisites first)
|
|
2. Impact (high-value features first)
|
|
3. Complexity (mix easy wins with harder tasks)
|
|
|

## RLM Context (Optional)
|
|
|
|
You have access to a large context file at:
|
|
**$RLM_CONTEXT_FILE**
|
|
|
|
Treat this file as an external environment. Do NOT paste the whole file into the prompt.
|
|
Instead, inspect it programmatically and recursively:
|
|
|
|
- Use small slices:
|
|
\`\`\`bash
|
|
sed -n 'START,ENDp' "$RLM_CONTEXT_FILE"
|
|
\`\`\`
|
|
- Or Python snippets:
|
|
\`\`\`bash
|
|
python - <<'PY'
|
|
from pathlib import Path
|
|
p = Path("$RLM_CONTEXT_FILE")
|
|
print(p.read_text().splitlines()[START:END])
|
|
PY
|
|
\`\`\`
|
|
- Use search:
|
|
\`\`\`bash
|
|
rg -n "pattern" "$RLM_CONTEXT_FILE"
|
|
\`\`\`
|
|
|
|
Goal: decompose the task into smaller sub-queries and only load the pieces you need.
|
|
This mirrors the Recursive Language Model approach from https://arxiv.org/html/2512.24601v1
|
|
|
|
## RLM Workspace (Optional)
|
|
|
|
Past loop outputs are preserved on disk:
|
|
- Iteration logs: \`logs/\`
|
|
- Prompt/output snapshots: \`rlm/trace/\`
|
|
- Iteration index: \`rlm/index.tsv\`
|
|
|
|
Use these as an external memory store (search/slice as needed).
|
|
If you need a recursive sub-query, write a focused prompt in \`rlm/queries/\`,
|
|
run:
|
|
\`./scripts/rlm-subcall.sh --query rlm/queries/<file>.md\`
|
|
and store the result in \`rlm/answers/\`.
