Create, inspect, or refresh a Codex + ECC multi-repository workspace with workspace-local ECC assets. Use when Codex needs to bootstrap a repo like codex-ecc, support Nix or portable Linux/macOS direnv setup, keep projects under repos/, copy ECC .codex and .agents/skills assets without touching ~/.codex, or update a workspace/instance to the latest ECC configuration.

Create reproducible, cross-platform development environments with Flox, a declarative environment manager built on Nix. Use when a project needs system-level dependencies, pinned toolchains, local services, macOS/Linux parity, team onboarding, or project-scoped tools that agents can install without sudo or system pollution. Also use when the user mentions .flox/, manifest.toml, flox activate, or FloxHub.

Structured self-debugging workflow for AI agent failures using capture, diagnosis, contained recovery, and introspection reports.

Build an evidence-backed ECC install plan for a specific repo by sorting skills, commands, rules, hooks, and extras into DAILY vs LIBRARY buckets using parallel repo-aware review passes. Use when ECC should be trimmed to what a project actually needs instead of loading the full bundle.

REST API design patterns including resource naming, status codes, pagination, filtering, error responses, versioning, and rate limiting for production APIs.

Write articles, guides, blog posts, tutorials, newsletter issues, and other long-form content in a distinctive voice derived from supplied examples or brand guidance. Use when the user wants polished written content longer than a paragraph, especially when voice consistency, structure, and credibility matter.

Backend architecture patterns, API design, database optimization, and server-side best practices for Node.js, Express, and Next.js API routes.

Build a source-derived writing style profile from real posts, essays, launch notes, docs, or site copy, then reuse that profile across content, outreach, and social workflows. Use when the user wants voice consistency without generic AI writing tropes.

Create or update Nix-managed skills in the spreadconfig repository. Use when the user asks to add, modify, register, expose, profile, or switch a skill that lives under spreadconfig/skills/local or is installed through skills/sources.nix, especially when they mention NixOS, Home Manager, agent-skills, workspace profiles, or avoiding direct edits to installed skill symlinks.

Create rigorous paper reading artifacts from PDFs, arXiv links, DOI pages, HTML, Markdown, or extracted text, including an opening summary and credibility assessment, a standalone key-question analysis, complete original text with Chinese parallel translation when legally available, and inline section summaries. Use when the user asks to read, translate, summarize, study, review, archive, or turn an academic paper into bilingual notes.

Umbrella workflow for turning WeChat public account articles into SecondBrain diary notes. Use when the user provides an mp.weixin.qq.com article and asks to write it as a diary, archive the article's original正文 under StudyLogNew/diary, include downloaded images, and add Codex's understanding inline with the original article content.

Conversational diary workflow for turning free-form chats into SecondBrain diary notes. Use when the user wants to talk through thoughts, experiences, technical progress, decisions, emotions, or reflections and later save the conversation as a new diary entry or append it to an existing diary entry in the SecondBrain repository. Use external research and links when public context, similar discussions, papers, forums, videos, news, or technical references would improve the conversation or diary. Search existing SecondBrain or Obsidian notes when related vault context could enrich the conversation or diary.

Manage diary notes in the SecondBrain repository. Use when Codex needs to create, update, organize, review, or search diary entries under StudyLogNew/diary, including daily learning logs, technical notes, personal analysis notes, Obsidian image embeds, frontmatter cleanup, tags, mtrace dates, and year-based resource handling.

Control local Waydroid or Android devices through Android Studio SDK adb for automated app debugging. Use when Codex needs to start/connect Waydroid, verify Android Studio/adb visibility, drive taps/swipes/text/keyevents, capture screenshots, dump UI XML, install/launch APKs, read logcat, or inspect app state from an Android runtime.

Coach SpreadZhao's LeetCode practice across the SpreadStudy code repository and SecondBrain notes. Use when the user asks to pick a LeetCode practice problem, run and review a LeetCode attempt, analyze compile/runtime/wrong-answer failures, provide minimal hints, create session records, generate note patches, or merge multi-language LeetCode learning into one SecondBrain note.

Use when checking disk, SSD, or NVMe S.M.A.R.T. health with root-only smartmontools commands, interpreting smartctl output, running self-tests, diagnosing smartd, or adding NixOS smartd monitoring configuration.
