Research Question

Research Question Loop

A sharpen → score → revise loop for the framing stage of research. The artifact is a small set of research questions; the feedback signal is how many clear the bar — each scored 0-5 on five fixed axes (Specific, Answerable, Novel, Feasible, Significant). You start from a vague topic, draft candidates, score each against the rubric (with a light novelty check against the literature), and rewrite the weakest axis of the promising ones until enough are strong.

A good research question is the hard part of research: too broad and it cannot be answered; too narrow and it does not matter; already settled and there is no point. The goal is a few excellent questions, not many mediocre ones — this loop drives toward the narrow band that is answerable, novel, and worth answering.

Scope & limitations

This loop produces and refines questions, grounded by a light novelty check (a few searches), not a full survey — for an exhaustive map use the literature-survey loop, and to turn a question into testable predictions use the hypothesis-generation loop. The novelty check needs web or literature access; without it (novelty_check: none), novelty is the loop's best judgment and must be labeled unverified.

When to use

Use when the user has a topic, area, or rough curiosity and wants it turned into concrete questions worth pursuing. Default: run the full draft→score→revise loop below. Escape hatch: if the user only wants candidates rated (no rewriting), score the set once and report the rubric breakdown. Not for grading a finished proposal, and not for generating hypotheses or experimental designs.

Setup

Resolve bindings interactively. If loop.run.yaml exists in the working dir, load it, confirm the values in one line, and skip to the loop. Otherwise: on Claude Code (the AskUserQuestion tool is available) infer a likely value for each binding and present it as the recommended option; on other hosts ask each as a quoted plain-text prompt. Then write loop.run.yaml (format: examples/run.example.yaml) and confirm the values before creating any other files.

| binding | meaning | default | how to infer | |---|---|---|---| | ` | the area of interest (field, population, scope, what the user already cares about) | — | ask the user | | | how many strong questions to deliver | 3 | — | | | rubric score (0-100) a question must clear to count as strong | 75 | a solid question without demanding perfection | | | how to check whether a question is already answered: lit \| web \| none | lit if the sibling skill is installed, else web | probe for the literature-search skill (below) | | | output question set | /questions.md | — | | | where the ledger and report live | ./sandbox | — | | ` | max iterations | 8 | — |

Novelty toolchain (only for novelty_check: lit). Paper search goes through the sibling literature-search skill ( = /tools/lit_search.py, with = python3 and ` its installed location, e.g. ~/.claude/skills/literature-search/); the relevant moves are search "" (is a direct answer already published?) and snippet "" (pinpoint the answering passage). Confirm --help works at setup; if the skill is absent, tell the user and either install it (copy the repo's loops/literature-search folder into ~/.claude/skills/) or degrade to web (host WebSearch/WebFetch) or none. Record the resolved choice in ` so re-runs are non-interactive.

The loop

The rubric (a fresh Grader scores each question 0-5 per axis — see grading below):

| Axis | 5 | 3 | 1 | |---|---|---|---| | Specific | one clear construct/relationship, well-scoped | direction clear, scope loose | broad/ambiguous topic, not a question | | Answerable | a concrete study/analysis could resolve it; the answer-shape is clear | resolvable in principle, approach unclear | not empirically/analytically decidable | | Novel | open per the novelty check; closest work cited | partly addressed; a real twist remains | already answered (check found a direct answer) | | Feasible | data/methods/access plausibly exist | feasible with effort | needs unavailable data or impossible measurement | | Significant | answering it changes understanding or practice | a useful increment | marginal even if answered |

Grading — spawn a fresh Grader per iteration (spawn-or-degrade). Each iteration, spawn a freshly instantiated Grader subagent — separate from whoever drafted or revised the questions, so the score is independent and not self-graded — and give it each candidate plus its novelty evidence. It returns the five raw 0-5 per-axis points (no weights). On Claude Code spawn it as a real Agent; otherwise adopt the Grader role inline in a clean pass. The orchestrator sums to a raw score out of 25, then converts to the 0-100 score used everywhere:

total = 100 × raw / 25 (e.g. raw 20/25 → total 80).

A question is strong when total ≥ and no axis scored 1 (a single fatal axis sinks it regardless of total).

Copy this checklist and tick items off:

• [ ] Iteration 0 — restate `` and what is interesting about it; draft 3-5 candidate questions spanning different angles (mechanism, comparison, condition/boundary, application). Record nothing as strong yet.
• [ ] Gather novelty evidence per candidate via ` ( search/snippet`, or WebSearch, or skip).
• [ ] Score — spawn a fresh Grader with each candidate + its evidence; it returns raw 0-5 per axis; convert raw/25 → total/100.
• [ ] Diagnose each promising question's lowest axis — the one thing keeping it from strong.
• [ ] Revise that one axis (one focused move per question); drop a fatally-flawed question revision cannot save; add a fresh candidate if short.
• [ ] Append a ledger row; stop when ` clear the bar, or at `.

Iteration 0 — frame & draft. Restate `` and what is interesting about it; draft 3-5 candidate questions spanning different angles. Record nothing as strong yet.

Then, until stop (` strong, or `):

1. Gather novelty evidence. Run the ` for each candidate's core:

search/snippet (or WebSearch). If a direct answer exists, note the closest answered work; if only related work exists, note the open part. Each call prints JSON; on failure it prints {"error","fallback"}` and exits non-zero — then fall back to WebSearch/WebFetch.

1. Score. Spawn a fresh Grader (spawn-or-degrade) and hand it each candidate plus its evidence;

it returns the raw per-axis points. Convert raw/25 → total/100.

1. Diagnose & revise. Find each promising question's lowest axis and make one focused move on

it: narrow an over-broad question to a specific population/condition; operationalize an unanswerable one into a measurable comparison; pivot an already-answered one toward the part the check showed is still open; raise significance by tying it to a decision or a contested claim. Drop questions with a fatal axis that revision cannot save; add a fresh candidate if you are short.

1. Log one ledger row and continue until `` are strong.

On stop, write ``: each strong question with its rubric scores, the novelty note (closest answered work / the open part), why it is answerable (the study-shape that would resolve it), and why it matters — plus any runners-up and the axis that held them back.

Ledger

/ledger.tsv, tab-separated, never commas in the text. Header:

iter	question	total	weakest_axis	revision

Example:

iter	question	total	weakest_axis	revision
0	how does sleep affect learning	35	specific	drafted; far too broad
1	does sleep timing affect retention	62	answerable	operationalized: spaced-review vs sleep-matched review, 1-week retention
2	does post-learning sleep within 3h beat delayed sleep for procedural retention	86	-	strong (novel per check: tested for declarative not procedural)

Report the best outcome — the strong questions and their scores — not necessarily the last iteration's set.

Constraints

• A few strong questions beat many weak ones — do not pad `` with questions that do not

clear the bar; report them as runners-up with the blocking axis instead.

• Novelty is checked, not assumed — when ` is lit/web`, actually search, cite

the closest answered work, and never claim novelty the check contradicts. When none, label novelty unverified.

• Grade with a fresh Grader scoring raw 0-5 per axis (no weights); the orchestrator converts

raw/25 → 100 and never lets the drafter/reviser grade its own questions, so the score stays honest.

• One focused revision per question per iteration, targeting its weakest axis, so improvement is

attributable and questions converge rather than thrash.

• Keep the rubric and threshold fixed so "strong" means the same thing throughout.
• The sandbox is self-contained — no ../ escapes. Do not pause the loop to ask whether to continue;

run until ` clear the bar or ` is hit.
