Stdlib-grounded Go engineering standards for implementing, reviewing, refactoring, or testing Go code. Use when Codex works on Go packages, CLIs, libraries, concurrency primitives, parsers, formatters, config loading, errors, documentation, examples, table-driven tests, fuzz tests, compatibility-sensitive APIs, or repository standards for high-quality Go code.

Restate the assistant's immediately preceding message in plain, concise language without jargon. Use only when the user explicitly invokes this skill to ask for a clearer version of the last response.

Implement code changes from reconciled project PRDs, ADRs, traceability matrices, executable acceptance scenarios, or a project-specs-reconciliation implementation handoff. Use after project-specs-reconciliation has created or updated the governing specs, or when the user explicitly says the specs are already reconciled. This skill owns the spec-to-test-to-code workflow and composes with language-specific TDD, BDD, and red-green-refactor skills without replacing their framework-specific guidance.

Create or update conventional project PRD and ADR documentation before implementation. Use when Codex needs to reconcile requested behavior, requirements, acceptance criteria, architecture decisions, technical tradeoffs, or implementation constraints into Product Requirements Documents under docs/PRD or a user-provided scoped PRD directory and Architectural Decision Reports under docs/ADR or a user-provided scoped ADR directory. This skill is responsible for project specification documentation and hands off code execution to project-specs-implementation.

Turn a rough draft, vague ambition, or messy task brief into a powerful Codex /goal objective for long-running autonomous work. Use when the user asks to write, improve, format, sharpen, stress-test, or activate a Codex goal, thread goal, durable goal, or /goal prompt.

Manages to-do items across multiple Google accounts using the Google Tasks API. Use when the user needs to create, update, complete, or organize tasks in Google Tasks, manage task lists, or view tasks across multiple Google accounts. Supports personal Gmail, Google Workspace, and organization-provisioned accounts with secure OAuth authentication.

Creates secrets in 1Password using the op CLI. Use when the user needs to store new passwords, API keys, login credentials, or secure notes in 1Password. Supports Login, Password, API Credential, and Secure Note item types with optional vault selection and password generation.

Deletes or archives secrets in 1Password using the op CLI. Use when the user needs to permanently remove items, archive deprecated credentials, or clean up unused secrets from 1Password vaults. Supports both permanent deletion and archiving for later recovery.

Reads secrets from 1Password using the op CLI. Use when the user needs to retrieve passwords, API keys, credentials, documents, or one-time passwords stored in 1Password. Supports reading items by name or ID, extracting specific fields, listing vault contents, and reading secret references.

Updates existing secrets in 1Password using the op CLI. Use when the user needs to modify passwords, edit field values, add or remove fields, rename items, move items between vaults, or manage tags on existing 1Password items. Supports all item types including Login, Password, API Credential, and Secure Note.
