- data-formshuytieu/COG-second-brainPick the right way to represent a dataset so a reader gets the finding in three seconds — a catalog of 20+ chart and diagram forms with when-to-use and failure modes, plus the encoding decisions that make any of them readable (takeaway headline, direct labels, kill the axis, highlight-and-mute, show the caveat). Style-agnostic — use with whatever palette or design system the destination already has. Use when charting survey results, benchmark data, usage metrics, or research findings for a post, brief, deck, or report, and whenever the default bar chart feels like it's burying the point.DocumentsNo warnings★ 1.3K↓ —Also in 1 other repo
- taste-skillhuytieu/COG-second-brainAnti-slop frontend skill for landing pages, portfolios, and redesigns. The agent reads the brief, infers the right design direction, and ships interfaces that do not look templated. Real design systems when applicable, audit-first on redesigns, strict pre-flight check.DesignNo warnings★ 1.3K↓ —Also in 1 other repo
- closed-loophuytieu/COG-second-brainRun one task through the V-model verification loop: CP-2 plan → CP-3 build → CP-3v component verify → CP-4 integration verify (full lane) → CP-5 acceptance. The worker never grades its own homework; evidence rows trace back to AC-n. Opt-in: invoke with /closed-loop or by asking for the closed loop, proper verification, or an evidence trail. Ordinary work does not run this.PlanningNo warnings★ 1.3K↓ —Also in 1 other repo
- daily-journalhuytieu/COG-second-brainA passive daily work journal that Claude keeps FOR you so you never have to write it yourself. Append short entries after meaningful work (what was done, what you focused on, artifacts touched) to 01-daily/journal/YYYY-MM-DD.md. Run a guided reflection at night or in the morning. Use when you run /daily-journal, say "log this to my journal", "add to today's journal", "reflect on today/yesterday", or when finishing a meaningful chunk of work in any session.WritingNo warnings★ 1.3K↓ —Also in 1 other repo
- nejm-abstractbrycewang-stanford/Awesome-Journal-SkillsUse to write the NEJM structured abstract — four headed sections (Background, Methods, Results, Conclusions), ≤250 words, with the trial registration number and funding source, leading the Results with the primary outcome reported as an effect size with a 95% CI. Late-stage polish skill.WritingNo warnings★ 1.4K↓ —
- kdd-submissionbrycewang-stanford/Awesome-Journal-SkillsUse when auditing a KDD submission for readiness in either cycle, covering Research vs ADS track declaration, OpenReview profile completeness for all authors, the ACM sigconf 8-content-page budget, double-blind checks, in-paper artifact references, resubmission declarations, and desk-reject triggers specific to ACM SIGKDD.ScienceNo warnings★ 1.4K↓ —
- mind-workflowbrycewang-stanford/Awesome-Journal-SkillsUse as the entry point for any Mind (philosophy journal) article. Routes to the right Mind sub-skill based on where you are in the lifecycle and whether the piece is an article, discussion note, book review, or critical notice. Mind is analytic philosophy — argument, not data — so the router's first job is to confirm there is a sharp thesis and a sound argument. It dispatches; it does not draft content.ProductivityNo warnings★ 1.4K↓ —
- nejm-citationbrycewang-stanford/Awesome-Journal-SkillsUse to convert references to NEJM's Vancouver / ICMJE numbered style — numbered in order of appearance, limited author lists then et al., NLM journal abbreviations, and a capped reference count. Late-stage style pass.OtherNo warnings★ 1.4K↓ —
- ndss-workflowbrycewang-stanford/Awesome-Journal-SkillsUse when planning an NDSS submission calendar — choosing between the summer and fall cycles, backward-planning from the AoE deadline through early-reject, rebuttal, notification, camera-ready, and the Seoul symposium, and placing NDSS honestly inside the security big-four retargeting year.ProductivityNo warnings★ 1.4K↓ —
- nejm-workflowbrycewang-stanford/Awesome-Journal-SkillsUse when deciding which nejm-* sub-skill to invoke next, or when sequencing a clinical manuscript from significance test through response to reviewers for The New England Journal of Medicine. Routes — it does not replace — the specialized skills.ProductivityNo warnings★ 1.4K↓ —
- nejm-rebuttalbrycewang-stanford/Awesome-Journal-SkillsUse after NEJM reviews arrive — often including a dedicated statistical reviewer and an editor letter — to triage the decision, answer statistical comments rigorously, and draft a point-by-point response that quotes each comment, the response, and the revised manuscript text. Do not run before the main text is actually revised.WritingNo warnings★ 1.4K↓ —
- pnas-workflowbrycewang-stanford/Awesome-Journal-SkillsUse when deciding which pnas-* sub-skill to invoke next, or when sequencing a manuscript from significance test through reviewer rebuttal for PNAS (Proceedings of the National Academy of Sciences). Routes — it does not replace — the specialized skills.ProductivityNo warnings★ 1.4K↓ —
- pnas-rebuttalbrycewang-stanford/Awesome-Journal-SkillsUse after PNAS reviews arrive to triage the decision, prioritize experiments, and draft a point-by-point response that is respectful, evidence-led, and honest about limits. Do not run before the main text is actually revised.OtherNo warnings★ 1.4K↓ —
- pnas-abstractbrycewang-stanford/Awesome-Journal-SkillsUse to write the PNAS abstract — a single self-contained paragraph of ~250 words, quantified and accessible to a broad scientific audience. Distinguishes the abstract (what/how/found, for scientists) from the Significance Statement (why-it-matters, for everyone). Late-stage polish.ScienceNo warnings★ 1.4K↓ —
- pldi-workflowbrycewang-stanford/Awesome-Journal-SkillsUse when planning a PLDI campaign across its annual clock — backward-planning from the November deadline through winter reviewing, the February response window, March notification, post-acceptance artifact evaluation, PACMPL production, and the June conference, with owners for each deliverable.ProductivityNo warnings★ 1.4K↓ —
- pnas-citationbrycewang-stanford/Awesome-Journal-SkillsUse to convert references to PNAS's numbered citation style — cited in order of appearance, a numbered reference list, full author lists, abbreviated journal titles. Provides formats for article/book/chapter/dataset/preprint and an author-date → PNAS conversion table. Late-stage style pass.MarketingNo warnings★ 1.4K↓ —
- pmla-workflowbrycewang-stanford/Awesome-Journal-SkillsUse as the entry point for any PMLA (Publications of the Modern Language Association) manuscript. Routes to the right PMLA sub-skill based on where you are in the lifecycle and which venue fits — a regular blind-reviewed article or a special feature (Theories and Methodologies, The Changing Profession, Criticism in Translation, Little-known Documents). It dispatches; it does not draft content.ProductivityNo warnings★ 1.4K↓ —
- soda-workflowbrycewang-stanford/Awesome-Journal-SkillsUse when planning a SODA (ACM-SIAM Symposium on Discrete Algorithms) campaign end to end — backward-planning to the July AoE deadline, SODA's seat in the theory calendar between STOC and FOCS deadlines, the September rebuttal and October decision, satellite deadlines (ALENEX, SOSA), and the January conference.ProductivityNo warnings★ 1.4K↓ —
