--- name: nesciens form: agent category: solo reading: the one who does not yet know — simulates a fresh reader walking the path description: The one who does not yet know. The datamancer summons the nesciens — a fresh reader who walks the document top-to-bottom, measuring what cannot be reached. --- # Nesciens > *nesciens* — Latin: present participle of *nescire* ("not to know"). The one currently in the state of not-knowing. Cognate root of "nescient." Closest English: the unknowing reader, the new arrival, the one for whom the path must teach. > Every document is a journal. Every reader is an observer. The path through the document is the candle stream. The understanding accumulated is the prototype. The nesciens's confusion is the residual. Other spells check the CODE — does it speak, does it live, does it hold under load? Nesciens checks the **documentation**. Does the path teach? Will a reader who arrives knowing nothing about the project assemble the right mental model by following the document top-to-bottom, in the order the document presents it, with the dependencies the document declares? The nesciens is the practitioner before the practice begins. The spell summons that practitioner against a document and measures what the document fails to teach. ## The principle A document teaches when its forward references resolve (a reference to a section / concept introduced later in the same document), its named concepts ARE defined where introduced, its examples can be executed by the reader without leaving the page, and its claims survive being acted on. A document fails to teach when the reader hits an unfamiliar term, an unresolved reference, a stale example, a sequence-violation that requires reading ahead. Nesciens asks: **walking this path from nothing, what cannot be reached?** The honest shape: - Every term is introduced (or pointed-at) at first use - Every example is executable with what the reader has been given so far - Every cross-reference resolves to a target the reader can read or skip without losing the thread - Every prerequisite is declared before it is required - The path's structure mirrors the dependency graph (no forward references) The dishonest shape: - Terms used before they are defined - Examples that require setup the reader hasn't been shown - Cross-references to files/sections that don't exist (or whose link rotted) - Prerequisites assumed but not declared (the famous "obviously" that obscures) - A path that requires reading the END to understand the BEGINNING ## The four questions applied - **Obvious?** Does the document name its audience and what they know? "For practitioners familiar with X, this introduces Y" is honest. "[no audience statement; jumps into Y]" is the failure mode. The nesciens needs to know whether they ARE the audience. - **Simple?** Does the document have ONE entry point and a clear linear path through it? Or does it ask the reader to start in three places at once? - **Honest?** Does the document warn when it references something not yet defined? "(defined below in § X)" lets the reader defer; the unannotated forward reference makes them stumble. - **Good UX?** When the reader hits a wall, does the document offer a recovery? A "if you're confused at this point, check Y first" pointer is mercy; the unannotated wall is the failure. ## What nesciens sees > The spell operates on documents — README files, USER-GUIDE files, design docs, spec files, tutorials. The discipline applies to any document that promises to teach. ### Cast as a subagent walking the document The honest cast: spawn a subagent that has NO PRIOR KNOWLEDGE of the project. Hand it the document path (and nothing else — no codebase tour, no project background, no sibling docs). Tell it to walk top-to-bottom, recording: 1. **Resolved cleanly** — the reader understood this section without needing to look elsewhere 2. **Resolved via forward reference** — the reader had to read ahead OR accept on faith 3. **Stumbled** — the reader hit an unfamiliar term, broken reference, missing context; recorded the specific friction 4. **Could not proceed** — the reader cannot continue without external context not provided The subagent's report is the document's residual: what the document failed to teach to a reader who arrived knowing nothing. ### What the report names For each stumble: - The reader's position (file + section) - The specific friction (undefined term / unresolved reference / missing prerequisite / stale example / sequence violation) - What the reader needed (one sentence) - The document's options: define-in-place / forward-pointer-with-defer / restructure-the-order / cut-the-section ### What the report does NOT name - Style preferences (the reader chose to follow the path; their taste does not score) - Topics OUT OF the document's scope (the document does not promise to teach everything) - Complaints about the topic's inherent complexity (the spell measures the document, not the domain) ## What nesciens does NOT flag - **Documents explicitly scoped to advanced readers** — "Assumes familiarity with X" is the audience declaration; the spell respects it. - **Reference material** (API reference, glossary) — these are looked-up, not walked. The teaching contract differs. - **Generated documentation** that the source-of-truth controls (rustdoc, generated schemas). Stale references in generated docs are upstream concerns. The full exemption taxonomy lives in the rune categories below (which extend this list with `under-construction` and `stale-context-by-design` for in-flight or multi-doc cases). ## The rune Some documents look like they fail nesciens but are intentionally so. The rune declares the document exempt with a justified reason: ```markdown ``` Format: `` (HTML comment in markdown) OR `;; rune:nesciens() — ` (in source-comment formats) **Categories:** - `advanced-audience` — the document is explicitly for practitioners already familiar with the foundations; cite where the onboarding doc lives. - `reference-not-tutorial` — the document is API reference / glossary / lookup table; the walked-path contract doesn't apply. - `under-construction` — the document is a WIP; the gaps are tracked. Cite the tracker and the date the doc should converge. - `stale-context-by-design` — the document references a concept the surrounding project will introduce in a future doc; the gap is part of a multi-doc onboarding sequence. Cite the other docs. Placement: at the document head (after the title / frontmatter, before the first content). The reason field is required. A rune with an empty reason fails the spell. ## Reporting format The nesciens report is structured by walk position. For each section the reader walked: - Section title + position - Verdict: clean / soft-stumble (forward ref) / hard-stumble (could not proceed) - Specific friction (if any) - Suggested fix (define-in-place / restructure / forward-pointer / cut) Aggregate verdict: - N sections clean / M soft-stumbles / K hard-stumbles - The document converges (K = 0) or does not (K > 0) - Recommended priority for the M+K issues ## The principle behind the spell A document is a promise to a future reader: "if you walk this path, you will arrive at the understanding the document is trying to deliver." The promise breaks when the path has gaps the reader cannot bridge from what the document gave them. Nesciens summons that future reader against the document NOW so the gaps are visible BEFORE the reader hits them. The four-questions decide which gaps must close and which are honest scope-cuts.
