- Breaks down weekly and trailing-4-week substacker performance per Substack section, keyed on section tags in corpus/published/ and section-map.md. Reports opens, clicks, subs-attributable-to-section per section with ≥3 posts. Skips if section-map has <2 sections. Feeds Curator with pruning candidates (sections with 4-week median z ≤ -1.0). Use when section-map has ≥2 live sections. Trigger keywords: per-section, section performance, section metrics, section pruning, differential engagement.
Per Section Tracking
Workflow
Per week (if ≥2 sections with ≥3 posts each):
- [ ] Step 1: Load section-map.md
- [ ] Step 2: Join CSV posts with corpus/published/{section}/ to map each post to section
- [ ] Step 3: Compute per-section aggregates (mean open rate, click rate, views/send, subs delta)
- [ ] Step 4: Compute trailing 4-week per-section z-score
- [ ] Step 5: Flag sections with median z ≤ -1.0 over 4 weeks → candidate for Curator prune proposal
- [ ] Step 6: Emit per-section table for the weekly report
Skip rule
- If section-map has <2 sections → skip, note "sections not yet established."
- If a section has <3 posts → exclude from per-section table; show in note: "{section} has <3 posts, not enough for section-level stats."
Output format (weekly-report subsection)
## Per section
| Section | Posts (week / total) | Open rate (week / 4w baseline) | Click rate (week / 4w baseline) | Sub delta | 4w z |
|---|---|---|---|---|---|
| kalshi-log | 2 / 6 | 0.54 / 0.51 | 0.06 / 0.05 | +8 | +0.7 |
| agent-workshop | 0 / 7 | — | — | +2 | +0.2 |
Narrative: 1-2 sentences per section summarizing what the numbers say (not interpretation — that's attribute-performance's job).
Guardrails
- Skip entirely if section-map empty or only one section.
- Skip any section with <3 posts.
- Never compare across sections' absolute numbers ("agent-workshop has higher open rate than kalshi-log"). Audiences differ; compare each to its own baseline.
- Section pruning flag is advisory — surfaces to Curator, Curator decides.
- Per-section z-scores use same IQR-based method as global baseline.
- Don't attribute causes in this skill (that's attribute-performance). Only describe the numbers.

--- name: advisory-edit description: A strict advisory-only editing discipline for a writer who dictates ("speaks out") essays and wants help WITHOUT having their voice changed. The editor directs structure, flags grammar, and suggests strategic language — but never modifies the writer's text unless the writer explicitly says "apply" / "make that change" / "rewrite this." Produces a line-referenced, suggestion-only critique where every item is marked the writer's call. Four passes: structural, l

VerifiedTrustedCommunity
Provides the house style for analyst-grade strategist writing — third-person register with sparing first-person, no em dashes, no "not X, not Y, not Z" negation cascades, numbered footnote citations rather than inline source parentheticals, specific opinion-signaling phrases, and topic-forward paragraph structure modeled on voice patterns observed in Damodaran's Musings on Markets and Thompson's Stratechery. Use when consolidating working notes into a finished long-form strategist or analyst report that must read as written by a senior human analyst rather than an AI assistant.

VerifiedTrustedCommunity
Renders a markdown report to a PDF using pandoc with xelatex (11pt serif body, 1-inch margins, numbered footnotes, formal heading hierarchy). Requires a one-time install of pandoc and a LaTeX engine on the user's machine — basictex on macOS or texlive-xetex on Linux. Does not attempt automatic install. Fails loudly with the exact install commands if pandoc or xelatex is missing on the user's PATH. Use when producing a finished strategist or analyst report PDF from a polished markdown source.

lyndonkl/worked-example-walkthrough
testing
VerifiedTrustedCommunity
Produces step-by-step computational walkthroughs of vector and matrix operations as a sequence of numbered "frames", showing the explicit state at each step. The text-equivalent of a 3Blue1Brown animation — each frame shows what changed and why, so the learner can re-trace the operation by hand. Use when the learner needs to *see* a computation unfold (eigenvalue computation, attention with 3 tokens, gradient descent step, SVD on a 2×2, layer norm on a 3-vector, softmax of a small input), when an explanation has been given but the learner needs to ground it in a worked example, or when introducing an operation that's intimidating in symbol form but trivial in pencil-and-paper form.
