Source Evaluator

Evaluate, triage, and actively read a set of research sources — books, articles, and online materials — by applying a dual-axis relevance-and-reliability screen, source-type skim protocols, and a two-pass active reading method that extracts data, arguments to respond to, and generative agreements and disagreements. Use this skill when you have a candidate source list and need to cut it to a workable set, when you need to verify that a source is credible before citing it, when you are reading sources to find a research problem or refine a hypothesis, when you need to take notes that accurately capture what a source argues without misrepresenting it, or when you must identify where sources agree and disagree so you can position your own argument within a field's conversation.

Argument Organization Reviser

Revise the structural organization of a research paper draft by applying a four-level top-down procedure — Frame (intro/conclusion alignment), Argument (section reasons + evidence ratios), Paper Organization (key-term threading + section signals), and Paragraphs (topic sentence placement + length). Use this skill whenever the user has a complete draft and asks to revise, reorganize, or strengthen its structure — not its prose style. Triggers include: user shares a draft paper and asks for structural feedback; user says sections feel disconnected or the argument is hard to follow; user's introduction and conclusion seem to contradict or not reinforce each other; user suspects their sections lack clear points or bury them in the middle; user cannot tell whether their evidence-to-reasoning ratio is balanced; user's paragraphs open with evidence rather than claims; user is preparing to submit and wants a final organizational pass. Also triggers on: "revise my structure," "does my argument hold together," "my advisor said the organization is unclear," "do my sections flow," "I need to check the coherence." This skill applies structural revision only — it does NOT revise prose style or sentence clarity (use prose-clarity-reviser for that), and does NOT rebuild an argument from scratch (use research-argument-builder for that).

Counterargument Handler

Anticipate, acknowledge, and respond to reader objections and alternative views in a research argument. Use this skill when the user has a draft argument or storyboard and needs to identify which objections readers will predictably raise, wants to decide which objections to acknowledge and which to set aside, needs vocabulary and sentence templates for introducing and responding to counterarguments without weakening their position, has discovered a flaw in their argument and does not know how to handle it honestly, is building a cause-and-effect argument and needs to address competing causes, has made claims with counterexamples that readers will invoke, uses key terms that readers may define differently and needs to address definitional scope, or wants to avoid either ignoring objections (seeming ignorant) or acknowledging too many (losing argumentative focus). This skill is the detailed companion to research-argument-builder — use it after assembling the argument's core structure (claim, reasons, evidence) and before drafting, to map every acknowledgment slot with a calibrated response strategy.

Data Visualization Selector

Select the correct graphic type (table, bar chart, line graph) for a dataset and rhetorical goal, then design and frame it to communicate evidence clearly and honestly. Use this skill whenever the user needs to present quantitative data in a research paper, report, thesis, presentation, or professional document and asks: which chart should I use, how should I visualize this data, how do I make this graphic clearer, is my chart misleading, how do I label or title a table or figure, or how do I introduce a graphic in text. Also triggers on: "my advisor said the table is confusing," "should I use a bar chart or line graph," "how do I make readers see my point in this figure," "is this graph ethical," "my chart looks amateurish," "the scale on my graph looks off," or any request to improve the visual communication of numerical evidence. Covers the full workflow: verbal-vs-visual decision → graphic type selection based on rhetorical effect → design simplification → framing with title, intro sentence, and labels → ethical integrity checks.

Prose Clarity Reviser

Revise dense, unclear prose into clear, readable sentences by applying four diagnostic principles — characters-as-subjects, actions-as-verbs, old-before-new information flow, and complexity-last sentence endings. Use this skill whenever the user shares a draft passage, paragraph, or document and asks you to make it clearer, more readable, easier to follow, less dense, less academic-sounding, or better written — even if they don't use those words. Also triggers on: "can you revise this," "this feels clunky," "my advisor said this is unclear," "make this flow better," "my writing sounds stilted," or any request to improve prose style in research papers, reports, essays, grant proposals, or professional documents. Apply all four principles end-to-end; return a revised version with brief annotations showing what changed and why.
