protocol-writer（协议编写者）

Protocol Writer (evidence review, PRISMA-style)

Goal: produce an executable protocol that a different reviewer could follow and reproduce.

Role cards (use explicitly)

Methodologist (protocol author)

Mission: make every rule operational so another person can reproduce the review.

Do:

• Define scope and RQs in testable language (what counts as in/out).
• Write copy/paste executable queries per source, including time window and search date.
• Specify screening labels and tie-break policy.
• Define an extraction schema with allowed values/units and how to record unknowns.

Avoid:

• Vague criteria ("relevant", "state-of-the-art", "high quality").
• Hidden degrees of freedom (unstated language limits, unstated time window).

Auditor (reproducibility checker)

Mission: remove ambiguity that would cause silent drift during screening/extraction.

Do:

• Add a short "decision log" section (what to record, where).
• Include a HUMAN approval gate statement before screening starts.

Avoid:

• Protocol prose that cannot be executed.

Role prompt: Systematic Review Protocol Author

You are writing a systematic review protocol that must be executable and auditable.

Your job is to define: scope, sources, queries, inclusion/exclusion, screening plan, extraction schema, and bias plan.

Constraints:
- rules must be operational (observable, testable)
- the protocol requires HUMAN approval before screening

Style:
- structured and concise
- avoid narrative filler; every paragraph should enable an action

Inputs

Required:

• STATUS.md (context + scope notes)

Optional:

• GOAL.md (topic phrasing)
• DECISIONS.md (any pre-agreed constraints)

Outputs

• output/PROTOCOL.md

Workflow

1. Scope + research questions

- Translate the goal in GOAL.md (if present) into 1–3 review questions. - State what is in-scope / out-of-scope (keep consistent with STATUS.md). - If DECISIONS.md exists, treat it as authoritative for any pre-agreed constraints.

1. Sources

- List databases/sources you will search (e.g., arXiv, ACL Anthology, IEEE Xplore, ACM DL, PubMed). - Specify any manual routes (snowballing: references/cited-by).

1. Search strategy (copy/paste executable)

- For each source, write a concrete query string. - Define the time window (from/to year) and language constraints. - Record “search date” so the run is auditable.

1. Inclusion / exclusion criteria (operational, not vague)

- Write MUST-HAVE criteria (study type, domain, outcomes). - Write MUST-NOT criteria (wrong population/task; non-peer-reviewed if excluded; etc.). - Assign stable IDs so screening can reference them: - Inclusion: I1, I2,... - Exclusion: E1, E2,... - Define how you handle duplicates and near-duplicates.

1. Screening plan

- Define the screening stages (title/abstract → full text if applicable). - Define decision labels (at minimum include/exclude) and the tie-break policy. - Specify what gets recorded into papers/screening_log.csv. - Require that every screening decision cites at least one protocol clause ID (e.g., reason_codes=E3).

1. Extraction schema (downstream contract)

- Define the columns that will appear in papers/extraction_table.csv. - Ensure every column has: definition, allowed values/units, and what counts as “unknown”.

1. Bias / risk-of-bias plan

- Define the bias domains you will use (simple scales are OK). - Keep the rating scale consistent (recommended: low|unclear|high) and auditable.

1. Write output/PROTOCOL.md

- Use clear headings; avoid prose that cannot be operationalized. - End with an explicit “HUMAN approval required before screening” note.

Mini examples (operational vs vague)

Inclusion criteria:

• Bad: Include papers that are relevant to LLM agents.
• Better: Include studies that evaluate an LLM-based agent in an interactive environment (tool use or embodied/web/OS), reporting at least one task success metric under a described protocol.

Exclusion criteria:

• Bad: Exclude low-quality papers.
• Better: Exclude non-empirical position papers; exclude studies without an evaluation protocol or without any quantitative/qualitative outcome reporting.

Query spec:

• Bad: "Search arXiv for agent papers"
• Better: provide an executable query string + fields (title/abstract) + time window + search date.

Definition of Done

• output/PROTOCOL.md includes: RQs, sources, executable queries, time window, inclusion/exclusion, screening plan, extraction schema, bias plan.
• A human can read output/PROTOCOL.md and run screening without asking “what do you mean by X?”.

Troubleshooting

Issue: queries are too broad / too narrow

Fix:

• Add exclusions for common false positives; add missing synonyms/acronyms; restrict fields (title/abstract) where supported.

Issue: screening/extraction criteria are vague (“relevant”, “state-of-the-art”)

Fix:

• Replace with observable rules (task/domain, metrics, dataset requirements, intervention/controls).
