direct-study

direct-study is a skill for Claude Code, Codex from agentlas-ai/agentlas-desktop. It costs 55 tokens per session (4,068 once invoked), scanned A, original, Apache-2.0.

A guided workflow for carrying out one scientific study from literature review through hypotheses, study design, data, analysis, robustness checks, conclusions, and a journal-ready manuscript. Each phase is gated and its sources, decisions, runs, and artifacts are recorded.

In plain words
What is it for?
Use it to manage an end-to-end research project, from defining a falsifiable question to validating the manuscript and journal submission materials.
Why use it?
It keeps a study’s reasoning and evidence connected from the initial question to the final paper. Gates help prevent unsupported conclusions or moving forward with missing research inputs.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

direct-study scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 14d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 228 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Direct One Study

Consult ../../agent/agent.md, ../../agent/soul.md, the durable state schema and ../write-manuscript/SKILL.md when useful. Reading or acknowledging a manual is never an execution prerequisite. The steps below are references to tools and evidence bindings, not a required order.

Default operating mode

Run autonomously: question -> acquire available data -> exploratory test -> inspect the result -> revise the hypothesis -> next experiment. Search literature in parallel, guided by the results. Data collection, feasibility scripts and exploration need no completed literature review or approved analysis plan. Keep exploration distinct from confirmatory inference; formal plans and journal validation apply only where the actual operation or final claim needs them. Open each result as it is produced and continue. Do not stop between stages for confirmation. Stop only for a host-required human receipt that is actually pending under the project's approval policy, a journal manual attestation, a Research Contract that Main returned as a draft/checkpoint, or a genuine fork: two or more materially different directions, an ambiguous request, or a missing required input. Main's exact Research Contract status approved plus its approval receipt, including a standing-policy receipt, satisfies contract approval and requires no second confirmation. The same rule applies when freeze_analysis_plan returns a frozen plan with an exact standing-policy approval: proceed with its returned version and hash, and never claim a human personally reviewed it. Incomplete plans and unresolved design decisions still fail closed. Ask with concrete options and a recommendation ("A or B? I recommend A because ..."). A bounded request ("just the literature review") ends at that scope with a report and a proposed next step; an unqualified study request remains active until its criteria are verified or a recorded blocker, budget exhaustion, or deadline stops it.

Record completion_scope: "full-study" for the whole study, or "bounded-deliverable" when the researcher explicitly limits the deliverable. For full-study work, keep the same loop and selected model through manuscript revision and the verified ready_to_submit gate. Inspect Main's progress and continuation receipts after each turn. Repeated proposals, unchanged lifecycle updates, or rewritten chat summaries do not establish progress. When Main reports a no-progress retry, choose a materially different evidence-bound action or persist the concrete blocker.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

direct-study is a skill published in the GitHub repository agentlas-ai/agentlas-desktop (6 stars, last pushed today), licensed Apache-2.0. It adds 55 tokens to every session and 4,068 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-04.
