Portable Agent Skills for disciplined software delivery, learning, editing, and LLM evaluation
Skill Codex
Edit and proofread Japanese speech-to-text transcripts from interviews, podcasts, lectures, classes, webinars, meetings, and videos while preserving every speaker's words, sequence, tone, and primary information without summarizing. Use when cleaning ASR or AI transcription errors, correcting punctuation and grammar…
Skill Codex
A Japanese-text editing skill based on ten editing approaches and ten methods. It keeps the facts and the writer’s voice while reshaping the text into knowledge with new connections, viewpoints, value, or narrative.
Skill Codex
A patient interactive teaching mode for deeply understanding a coding session, PR, diff, concept, architecture, or other completed work. Use when the user asks to be quizzed, coached, taught what was just done, walked through a solution, or to verify their understanding rather than receive a passive summary. Drive an…
Skill Codex
Turn Japanese text, articles, meeting notes, reports, transcripts, URLs, and files into a quick 1-3-1 summary: one-sentence gist, up to three essential points, and one important caution or condition when needed. Use when the user asks for a 1-3-1 summary, a quick overview, content at a glance, or a short and easy way…
Skill Codex
Transform Japanese text, conversations, articles, reports, meeting notes, transcripts, URLs, and files into an adaptive, neutral summary that is immediately understandable without losing essential facts, relationships, or caveats. Use when the user asks for make-clear-summary, a clear summary, an easy overview, a…
Skill Codex
A Japanese summarisation tool based on a structured set of 36 rules for making a message clear within a requested length.
Skill Codex
Transform AI conversations, meeting notes, research, and complex ideas into clear Japanese business documents for third-party readers. Use when Codex needs to document project discussions, explain a new concept step by step, turn transcripts or rough notes into reports, decision records, proposals, or explanatory…
Skill Codex
Write Japanese articles, reports, proposals, explanations, and decision documents from supplied evidence while preserving provenance and separating facts, interpretations, hypotheses, and proposals. Use when the user needs evidence-grounded writing, claim-to-source traceability, citation-aware drafting, conflict…
Skill Codex
A guide for planning a software system’s structure, including its layers, components, dependency directions, and boundaries. It also organises ADRs, which are short records explaining important architecture decisions.
Skill Codex
A software-design approach for modelling a business domain: the real-world rules, concepts, and relationships a system must represent. It defines shared terms, boundaries, entities, value objects, groups of related data, and domain events.
Skill Codex
A software-release guide covering checks and safeguards before, during, and after deploying a change. Deployment means putting new or changed software into an environment where it runs.
Skill Codex
A tool for rerunning the Japanese LLM Benchmark, a test suite that compares language models on tasks such as summarising Japanese text, extracting keywords, coding, and visual evaluation.
Skill Codex
A guide for making software easier to monitor and investigate through logs, metrics, traces, alerts, and dashboards. These records show what the system is doing and help reveal problems.
Skill Codex
A post-project review tool that analyzes an AI agent’s work, results, and user feedback. It turns the review into possible When/Then rules for improving future behavior, without directly making them permanent instructions.
Skill Codex
A code-improvement guide for changing a program’s internal structure while keeping its observable behavior the same.
Skill Codex
A code-review guide that checks changes for fit with the specification, correctness, security, performance, maintainability, and testing.
Skill Codex
A software-development process for turning tasks into checkable work agreements, staged implementation, quality checks, and evidence-based completion reviews.
Skill Codex
A security review process covering threat modeling, access control, secret handling, dependencies, input checks, and testing from an attacker's point of view.
Skill Codex
A tool for analysing several post-project learning logs and deciding which lessons should change an AI agent's skills, checklists, workflows, templates, tool rules, questions, or local notes. It classifies lessons by scope and proposes scored skill patches.
Skill Codex
A checker for proposed updates to coding-agent skills, checklists, workflows, templates, and tool-use rules. It tests whether an update could break useful existing behavior or add unnecessary complexity.
Skill Codex
A service-reliability planning skill covering measures and targets for service quality, incident response, post-incident reviews, and reducing repetitive operational work.
Skill Codex
A test-driven development (TDD) workflow that turns a test contract or acceptance conditions into a small, verifiable code change. TDD means using tests to guide implementation through failing, passing, and cleanup stages.
Skill Codex
A test-planning skill that turns a specification's requirements and acceptance conditions into observable results, test scenarios, evidence, and proof obligations. TDD means writing tests or defining expected behavior before implementation.
Skill Codex
Guidance for designing user interfaces and React applications around users' ability to complete tasks. It also covers accessible and consistent interface construction.
