| description | Karpathy-pattern autoresearch — autonomous hill-climbing over a measurable metric, deep multi-agent research, or research-then-optimize. Three modes: Optimize (keep/discard ratchet), Research (STORM multi-perspective), Improve. |
| when_to_use | This skill should be used when the user asks for "autoresearch", "experiment loop", "optimize autonomously", "deep research", "hill climbing", "Karpathy loop", "iterative optimization", or "keep trying until it improves". Also triggers when hitting a numeric target (latency, bundle size, compile time, throughput, loss, pass rate) autonomously, running multi-source competitive analysis, or improving prompt quality without a defined starting point. |

Autoresearch
An autonomous agent that finds improvements through measured experiments or deep
research. Based on Karpathy's autoresearch pattern: separate what the human controls
(strategy) from what the agent controls (execution), then let the agent iterate
indefinitely with objective verification.
Choosing a Mode
| Mode | Command | When to use |
|---|
| Optimize | /autoresearch optimize | There is code/config/prompt + a way to measure quality. Find improvements autonomously. |
| Research | /autoresearch research | Deep, multi-source research on a topic with synthesis. |
| Improve | /autoresearch improve | Improve something without a clear starting point. Research best practices first, then apply via the optimize loop. |
When no mode is specified, infer from context: metric or benchmark mentioned → Optimize.
Question or topic exploration → Research. Wants something "better" without a defined
measure → Improve.
Mode 1: Optimize (Experiment Loop)
The core Karpathy pattern. A hill-climbing ratchet where only measurable improvements
accumulate.
Step 1: Configure the Experiment
Before looping, establish four components. Ask the user to confirm if anything is
ambiguous — but if the project structure makes the answers obvious, just proceed.
| Component | What it is | Example |
|---|
| Truth Layer | Read-only files that define correctness — tests, specs, data, eval harness. The agent never modifies these. | tests/, prepare.py, benchmark.sh |
| Mutable Surface | The file(s) the agent modifies each iteration. Keep this as small as possible — a focused surface leads to cleaner experiments. | train.py, config.yaml, prompt.md, src/hot-path.rs |
| Verifier | A command that produces a numeric metric. Lower or higher is better (establish direction). Must be deterministic enough that noise doesn't dominate signal. | pytest --tb=short, ./bench.sh, npm run perf |
| Metric | The specific number to extract from verifier output, and the direction of improvement. | val_bpb (lower is better), throughput_rps (higher), pass_rate (higher) |
Read references/experiment-loop.md for auto-detection heuristics when the user
doesn't specify these explicitly.
When to suggest classical tools instead: For pure numeric parameter sweeps
(no code logic — YAML thresholds, hyperparameters), mention that Optuna or BOHB
may converge faster. Autoresearch's edge is mutating arbitrary code and algorithms.
Don't gate on this; just note it so the user can choose.
Step 2: Establish Baseline
- Create a git branch:
autoresearch/<descriptive-tag> from current HEAD
- Read all mutable surface files to build full context
- Run the verifier once unmodified to get the baseline metric
- Record in
results.tsv (see "Results Ledger" below for the canonical schema):
commit metric delta status duration_s description
<hash> <value> 0 baseline <s> Initial measurement
Step 3: The Loop
Run this loop autonomously without pausing for confirmation. The user may be asleep,
at lunch, or doing other work — they will interrupt when they want it to stop.
Note that Bash is pre-approved only for git * commands — the Step 2 baseline run
doubles as the permission warm-up for the verifier command, so it gets approved
while the user is still present, not mid-loop while they are away.
LOOP:
1. HYPOTHESIZE: Read results.tsv, recent verifier output (errors, warnings,
timing breakdowns — not just the scalar), and the mutable surface. Form
one specific hypothesis with expected impact and rationale.
2. MUTATE: Apply exactly ONE atomic change. Small reversible edit over large
rewrite. Never bundle. Don't retry discarded ideas without a meaningfully
different approach. ANNOTATE non-obvious values inline per "Provenance
Comments" below.
3. COMMIT: `git add <mutable files> && git commit -m "experiment: <description>"`
4. RUN: Execute the verifier. Capture ALL output; retain ~200 lines for the
next HYPOTHESIZE (warnings, profiling, timing are signal).
- Trivial bug (typo, import): fix and retry once, else log "crash".
- Duration >2x baseline: kill, log "timeout".
5. MEASURE: Extract the metric from the output.
6. DECIDE:
- IMPROVED: Keep the commit as new baseline. Log "kept".
**Anomaly check:** If delta >3x rolling average of kept deltas AND
follows 3+ consecutive discards, flag: `⚠ ANOMALY: delta=X is Nx rolling
avg after plateau — inspect for reward hacking.` Pause one iteration to
reflect. Do NOT auto-discard — could be a breakthrough — but be suspicious.
- EQUAL: Keep ONLY if simpler (fewer lines, simpler logic). Log
"kept-simpler" or "discarded-no-gain".
- REGRESSED: `git revert HEAD --no-edit` (preserves history). Log "discarded".
7. LOG: Append to results.tsv (commit, metric, delta, status, duration_s, description).
8. STATUS: Print `[iteration N] metric=X delta=Y status=Z`
9. REFLECT (every 5): Re-read results.tsv. Categorize experiments (hyperparameter,
algorithmic, structural, config). If last 5 are same category, force a
different category next. Print `[reflect] N kept from <cat>, pivoting to <new>`.
10. GOTO 1
Stopping Conditions
At 5 consecutive discards (plateau — likely a local maximum), do NOT stop yet:
apply the escape strategies in references/experiment-loop.md §"Local Maxima"
and pivot to a different hypothesis category.
Stop the loop when ANY of these are true:
- Ceiling mapped: 8+ consecutive discards spanning at least 3 different hypothesis
categories. This is not a failure — it means the optimization space has been explored
and the system is near its ceiling. Report it as a positive finding:
✓ Optimization ceiling mapped at <metric>=<value>. Tried <N> experiments across <categories>. The system is near-optimal for the current architecture/approach. Further gains likely require a fundamentally different strategy.
- Target reached: The user specified a target metric and the loop reaches it
- User interrupt: The user sends any message
- Iteration cap: 20 iterations by default (user can override with
--max N)
When stopping, print a summary table of all experiments and the cumulative improvement.
The Simplicity Criterion
Prefer deletions. A change that removes code for equal-or-better metric is always
worth keeping; a small gain that adds ugly complexity is not. The git history should
read as a clean sequence of wins, not a pile of hacks.
Mode 2: Research (Deep Multi-Agent Research)
Recursive depth+breadth research with parallel agents. Produces a comprehensive,
source-grounded report.
Step 1: Decompose the Question
Break the user's question into 3-6 independent research angles. Use the STORM
multi-perspective pattern — don't just split by subtopic, split by viewpoint:
- What would a practitioner want to know?
- What would a skeptic question?
- What does the academic literature say?
- What are the competing approaches?
- What are the failure modes and edge cases?
Step 2: Dispatch Parallel Research Agents
For each angle, spawn a subagent using the Research Agent Prompt Template in
references/deep-research.md. Each agent returns structured LEARNINGS,
CONTRADICTIONS, FOLLOW_UPS, SOURCES, and a CONFIDENCE rating.
Step 3: Synthesize and Recurse
After all agents return:
- Merge learnings — deduplicate, resolve contradictions, note confidence levels
- Identify gaps — what follow-up questions are most important?
- Recurse if needed — for the top 2-3 follow-up questions, dispatch another round
of agents. Reduce breadth by half each level. Default depth: 2 levels.
Configurable with
--depth N and --breadth N.
- Synthesize — produce a structured report with: Executive Summary, Key Findings
(by theme, not by source), Competing Perspectives, Gaps/Uncertainties, and Sources.
Read
references/deep-research.md for report templates, agent prompt templates,
and synthesis patterns.
- Save — write the final report to
results/<topic>-research-<date>.md. This
file serves as the provenance record. Code changes informed by this research
should reference it in comments (see "Provenance Comments" in Mode 1).
Depth Control
| Setting | Queries | Depth | Good for |
|---|
| Quick | 3-4 | 1 | Factual questions, quick overviews |
| Standard | 5-8 | 2 | Most research tasks (default) |
| Deep | 8-12 | 3 | Complex topics, competitive analysis |
| Exhaustive | 12+ | 4 | Due diligence, literature reviews |
The user can specify: /autoresearch research --depth deep "topic"
Mode 3: Improve (Research-then-Optimize)
For when the user wants something better but doesn't yet know what "better" looks
like. This mode runs Research first to discover best practices, then Optimize to
apply them.
Phase 1: Research
Identify what the user wants to improve (code, config, prompt, workflow), then run
Mode 2 targeting: best practices for this type of artifact, common performance
pitfalls, what the state of the art looks like, and specific techniques that have
worked for others. Present the findings to the user as a brief summary (not the
full report) and propose a metric + verifier grounded in them.
If the metric is subjective (quality scores, "is it better?", LLM-as-judge),
recommend converting to 3-5 binary pass/fail assertions instead. Binary evals
(e.g., "Does the output contain X?", "Is the response under N tokens?", "Does it
compile?") resist drift and enable truly autonomous operation. Fuzzy 1-5 rubrics
cause the agent to score itself leniently over time. A test either passes or doesn't.
Phase 2: Optimize
Present the proposed experiment configuration to the user — truth layer, mutable
surface, verifier command, metric + direction, and the top 5 hypotheses ranked by
expected impact from the research — then let them confirm or override and enter
the Mode 1 loop. Order hypotheses research-informed first, speculative later. When
keeping changes informed by the research phase, include provenance comments that
reference the research file (e.g., See results/<topic>-research-<date>.md).
The research phase turns blind exploration into targeted experimentation.
Operational Details
Git as State Machine
Always work on branch autoresearch/<tag>, never on main/master. Never force push.
The branch tip is always the best-known version — commit on keep, git revert HEAD --no-edit on discard. If not in a git repo, keep a copy of the last-known-good
version of the mutable surface and restore it on discard instead.
Results Ledger
Track all experiments in results.tsv (append-only) at the project root:
commit metric delta status duration_s description
abc1234 0.9979 0.0000 baseline 301 Initial measurement
def5678 0.9952 -0.0027 kept 298 Increased depth from 8 to 12
Read this before each hypothesis to avoid repeating failed ideas.
Provenance Comments
Leave inline comments on non-obvious experimentally-derived values so future readers
don't have to reconstruct the reasoning from git blame or chat history. Include:
the autoresearch: prefix, before→after metric, why it works, and a pointer to
results.tsv or the research report. Skip obvious defaults and self-explanatory diffs.
BATCH_SIZE = 384
When Mode 2/3 research informed a choice, reference the report file instead.
End-of-Session Summary Comment
When the optimize loop stops, add a block comment at the top of the primary mutable
file: session branch/date, metric baseline→final, iteration count (kept/discarded),
key changes that moved the needle, and a pointer to results.tsv. Append below any
previous session comments — don't replace them.
Crash Handling
Don't get stuck — if an experiment fails, extract signal and move on:
- Trivial bug (typo, import): fix and retry once, then discard
- Runtime crash: apply obvious fix or log as "crash" and move on
- Timeout (>2x baseline): kill, discard, log as "timeout"
- Flaky results: run verifier twice and average; note variance >5%
Blind Validation (Subjective Metrics)
Skip for objective metrics (latency, bytes, pass rate) — the number is the number.
For subjective metrics (LLM-as-judge, rubric scores, design ratings), the agent
that proposed a change is biased toward keeping it. Counter by spawning a blind
evaluator subagent — once on a baseline snapshot (background), once on the final
version — and comparing Self / Agent / Gap per component. A gap ≥2 flags that
component for the next hypothesis; the blind score surfaces bias, it never
overrides the self-score.
See references/experiment-loop.md (Blind Validation Protocol) for when to spawn,
the agent prompt template, and the comparison-table format.
