**Metric**: {FILL_IN: what we optimize, e.g. val_bpb, accuracy, F1} (lower/higher is better)
**Metric**: {FILL_IN: metric name} ({lower/higher} is better). Target: 5-40 min per run.
**Metric design requirements** (enforce before first real experiment):
- Train + eval runs in 5-40 minutes on your GPU
- Variance across seeds < effect size of a meaningful improvement (run baseline x3, check std)
- Deterministic given same seed (fixed data order, fixed eval split)
- If variance is too high: use more eval data, smaller model, or a proxy metric with less noise

## Agent Algorithm
```
YOU ARE AN AGENT. Follow this loop:
```python
# MUST read before starting:
read RESEARCH_JOURNAL.md # what has been tried, what worked/failed
read "Lessons Learned" below # gotchas -- don't repeat past failures
read RESEARCH_JOURNAL.md # what has been tried
read 0_docs/problem.md # what we're solving
n_ideas = count files in 1_ideas/ (not _TEMPLATE.md)
n_ideas = count(1_ideas/*.md) - 1 # minus _TEMPLATE.md
if n_ideas < 30:
## IDEATE
- Read at least one file from 0_docs/papers/ (or fetch a new paper)
- Do at least one web search for recent approaches
- Fetch papers: use /semantic-search or /exa-search skills
-> save FULL paper text to 0_docs/papers/{slug}.md (not summaries -- full text)
-> optionally add a vargdown-style argument map to 0_docs/papers/{slug}_analysis.argdown
-> add key insight (1-3 observations with sources) to RESEARCH_JOURNAL.md
- Brainstorm ideas. Quality bar:
* Novel (not in RESEARCH_JOURNAL.md already)
* Mechanistically grounded (not just hyperparameter tuning)
* Not sklearn slop -- must be a real ML research contribution
* Bold enough that it could be a paper contribution
- For each idea:
write 1_ideas/{YYYY-MM-DD}_{slug}.md (use _TEMPLATE.md format)
spawn subagent to critique the idea (prompt: "Is this idea sound?
What are the failure modes? Is the hypothesis testable?")
append subagent feedback to the idea file
- Append summary of new ideas + paper insights to RESEARCH_JOURNAL.md
# IDEATE
# MUST read: 0_docs/ideation_guide.md (epistemics, paper fetching, brainstorm discipline)
read 0_docs/problem.md
search 1+ papers (semantic-search, exa-search, bibtex MCP)
save full paper text to 0_docs/papers/{slug}.md # full text, not summaries
for each idea:
write 1_ideas/{YYYY-MM-DD}_{slug}.md # use _TEMPLATE.md
subagent critique: "Is this sound? Failure modes? Testable?"
append subagent feedback to idea file
append paper insights + ideas to RESEARCH_JOURNAL.md
else:
## IMPLEMENT
pick the best idea from 1_ideas/ based on:
- subagent rating (see feedback section in idea file)
- novelty relative to RESEARCH_JOURNAL.md
- expected impact on metric
- implementation feasibility
# IMPLEMENT
# MUST read: 0_docs/conventions.md (coding style)
pick best idea (subagent rating + novelty + expected impact)
just worktree {slug} # creates 5_worktrees/{slug} on branch exp/{slug}
implement in worktree (edit train.py; do NOT touch eval.py, program.md)
slug = idea filename slug
run: git worktree add 5_worktrees/{slug} -b exp/{slug}
cd 5_worktrees/{slug}
# TEST
subagent code review vs idea doc
just smoke
just eval # appends row to results.tsv
implement the idea (modify train.py, model.py, etc.)
do NOT modify: eval.py, program.md, meta_journal.md
# REPORT
write 9_reports/{YYYY-MM-DD}_{slug}.md # use _TEMPLATE.md
append to RESEARCH_JOURNAL.md: what tried, delta metric, observation vs inference
## TEST
spawn subagent: "Code review this against the idea doc 1_ideas/{slug}.md.
Does the implementation match the hypothesis? Any bugs?"
run: just smoke # fast sanity check
run: just eval # appends to results.tsv
## REPORT
write 9_reports/{YYYY-MM-DD}_{slug}.md (use _TEMPLATE.md format)
append short summary to RESEARCH_JOURNAL.md:
- what was tried, what metric changed, what you learned
- key observation vs inference distinction
## SUBMIT
git commit -m "exp({slug}): {one-line description}"
# SUBMIT
git commit -m "exp({slug}): {one line}"
git push origin exp/{slug}
if result beats best in results.tsv:
create PR for human to merge
if beats best in results.tsv: open PR for human
## QUEUING EXPERIMENTS (pueue)
Use pueue to queue experiments for the single GPU -- one at a time, no collision:
# Queue with a label showing the question and expected resolution
pueue add --label "Q: does X help? H: expect +0.05 metric" -- just eval --config=path
# Check queue / status / logs
pueue status
pueue log {task_id} # full stdout
pueue follow {task_id} # live tail
Labels encode the hypothesis being tested. After the run, append observed vs expected
to RESEARCH_JOURNAL.md. The label shows up in `pueue status` so you can track what
question each running/queued job is answering.
# Example: multiple experiments queued with different hypotheses
pueue add --label "Q: rotary vs sinusoidal? H: rotary saves 0.1 bpb" -- just eval rotary
pueue add --label "Q: flash-attn memory? H: 2x batch size same speed" -- just eval flash
pueue add --label "Q: does layer norm placement matter? H: pre-norm better" -- just eval prenorm
# GPU QUEUE (pueue -- one GPU, no collision)
just queue "Q: does X help? H: expect +delta" eval {args}
pueue status # shows hypothesis label for each queued/running job
```

## Coding Conventions
## Lessons Learned and Gotchas
Fail fast. No defensive programming. No silent fallbacks.
Format: `YYYY-MM-DD | title | lesson (one line)`
```python
# shape ops: einops for clarity
from einops import rearrange, reduce
x = rearrange(x, 'b s h d -> b h s d')
# einsum for explicit contraction
out = torch.einsum('b h s d, b h d v -> b h s v', q, k)
# jaxtyping on function boundaries (docs + smoke-test checking)
from jaxtyping import Float
from torch import Tensor
def encode(x: Float[Tensor, 'b s d']) -> Float[Tensor, 'b s h']:
...
# logging: loguru not print
from loguru import logger
logger.info(f"loss={loss:.4f}")
# dataframes: polars v1
import polars as pl
df.group_by("exp").agg(pl.col("metric").mean())
# config: tyro dataclass
import tyro
from dataclasses import dataclass
@dataclass
class Config:
lr: float = 3e-4
# {FILL_IN}
cfg = tyro.cli(Config)
```
---
## Research Epistemics
Separate observations from inferences:
- **Observation**: "val_bpb dropped from 3.2 to 2.9 on run X" (measured fact)
- **Inference**: "this suggests the attention head is learning positional structure" (interpretation)
- **Claim from paper**: "authors claim X" -- not "X is true" unless you verified it
For complex arguments, use `/vargdown` skill: verified argument maps with credences.
Trust signals: community adoption > papers citing it > open source code > author reputation.

## Meta-Mode
Human sets `META_MODE=1` to enable editing of FROZEN files and committing to main.
Use meta-mode to:
- Revise this program.md (agent instructions)
- Update eval.py (e.g., add new metric columns)
- Reflect on the overall research process in meta_journal.md
- Exit-interview style: what worked, what didn't, what would you change?
To enter: human writes `META_MODE=1` in human_journal.md entry before asking agent.
Human writes `META_MODE=1` in `human_journal.md` to unlock editing FROZEN files and committing to main. Use for: revising this program.md, updating eval.py, exit-interview style process reflection in meta_journal.md.
