Conciseness

The body is dense and almost entirely skill-specific (no explanation of concepts Claude already knows), but at ~500 lines it could be tightened: "Screening starts only when the user asks for it" is stated twice (Screening boundary and the Checkpoints close), reviewer independence is justified both in the Agent Team section and anti-pattern 5, and the ~20-line routing-core block plus the instruction-data-boundary excerpt are suite-level orchestration content rather than skill operation. Not 4: these duplications and off-scope blocks are more than minor trimmable instances; not 2: the bulk of the text is operational, not padded explanation.

Actionability

Guidance is fully executable: a copy-paste bash sequence with exact flags ("python $S/prepare_records.py --inputs exports/ --work sr_work --config screening_config.json", "merge_decisions.py --work sr_work --from <run folder or journal.jsonl> --config screening_config.json --pilot-labels pilot_labels.csv"), a concrete per-role models JSON block, the per-record output contract "{id, d, code, why}", and named output files per mode. Not 4: commands and examples cover the common cases completely; placeholders like <this skill's folder> are unavoidable, not gaps.

Workflow Clarity

The 7-phase orchestration is explicitly sequenced, and the 7 numbered checkpoints are hard validation gates for batch operations: the pilot gate ("build_workflow.py ta refuses the full run... until every labelled record has been compared"), no-silent-defaults ("A record without a valid decision from each required reviewer stays pending"), cost check before fan-out, and error-recovery loops ("If a run stops... merge what exists, then run build_workflow.py --jobs pending", "stop, amend, re-pilot"). The Failure Paths table adds per-situation recovery steps. This is the anchor-5 pattern of explicit validation plus feedback loops.

Progressive Disclosure

Structure is good: the body is an overview with one-level-deep, clearly signaled references, and the Reference Files and Scripts tables map every file to its purpose; all 7 references/ files and all 6 scripts/ files referenced in the body exist in the bundle and match their descriptions (orchestration.md § 5 mode recipes, failure_paths.md F1-F15 verified). Not 5: the body also references agents/*.md (four agent files), templates/prompts.md, templates/screening_config.template.json, templates/workflows/*.js, examples/*, and MODE_REGISTRY.md, none of which are present in the bundle, so navigation breaks for those paths.

Specificity

The description lists many concrete actions with comprehensive coverage: "Turns a proposal or PROSPERO protocol into confirmed eligibility rules, then screens titles/abstracts and full texts", "ordered exclusion codes, no silent defaults, resumable batch runs, QC (seed studies, near-miss rechecks, kappa and PABAK), PRISMA 2020 counts, EndNote/Zotero RIS groups, an Excel log, a methods draft", plus input handling ("Reads RIS, PubMed .nbib, Web of Science and CSV exports; removes duplicates") and the 8 named modes. Not 4: the action inventory has no meaningful coverage gaps.

Completeness

Both questions are explicitly answered: the "what" is a full capability and mode inventory, and the "when" is a dedicated "Use it to screen records against eligibility criteria, pilot screening, resolve screening conflicts, audit exclusions or report the selection process" clause followed by concrete trigger phrases. Not 4: the when-clause is fully explicit, not merely present.

Trigger Term Quality

"Triggers on: screen these papers, title/abstract screening, full-text screening, screening conflicts, inclusion criteria, PRISMA flow" covers the natural English phrases, and the Persian triggers (غربالگری مقالات, اسکرینینگ عنوان و چکیده, معیارهای ورود و خروج) plus named file formats (RIS, .nbib) give synonym- and extension-level coverage a real user would produce. Not 4: no common natural variant of the screening request is missing.

Distinctiveness Conflict Risk

The niche (protocol-driven screening as a distinct stage, with named handoffs to deep-research and academic-paper) is clear, but "inclusion criteria" and "PRISMA flow" are phrases a user asking for a whole systematic review or manuscript help would also naturally say, and the description does not state that boundary. Not 5: anchor 5 requires minimal conflict risk, and these shared phrases create minor overlap with the closely related deep-research systematic-review mode; not 3: the overlap is limited to closely related skills, not a broad set.
