Install hotl for Codex

Installs for the current user
codex plugin marketplace add hashgraph-online/awesome-codex-plugins
codex plugin marketplace upgrade awesome-codex-plugins

Included Skills20

brainstormingskills/brainstorming/SKILL.md

Use before any feature work — explores intent, requirements, and design. Produces HOTL contracts (intent, verification, governance) before implementation.

code-reviewskills/code-review/SKILL.md

Use after completing implementation steps and before merging — reviews against plan and HOTL contracts.

dispatch-agentsskills/dispatch-agents/SKILL.md

Use when you have 2+ independent tasks with no shared state — dispatches parallel subagents for each task.

document-reviewskills/document-review/SKILL.md

Optional utility for reviewing existing docs, external specs, hand-authored notes, or non-HOTL documents. HOTL design docs and workflows get structural lint + AI review; other documents get AI-only review with a generic rubric.

executing-plansskills/executing-plans/SKILL.md

Use when executing an implementation plan linearly with explicit human checkpoints between batches of tasks.

finishing-a-development-branchskills/finishing-a-development-branch/SKILL.md

Use after execution is complete or intentionally stopped — decide whether to merge back, publish a PR branch, keep the execution checkout, or discard it, and record that disposition in HOTL state.

governed-executionskills/governed-execution/SKILL.md

Use when executing an accepted HOTL workflow through the best available host or fallback driver.

loop-executionskills/loop-execution/SKILL.md

Use when executing an existing HOTL workflow file — reads steps, loops until success criteria met, auto-approves low-risk gates, pauses at high-risk gates.

pr-reviewingskills/pr-reviewing/SKILL.md

Review a PR across multiple dimensions — description, code changes, code scan, unit tests — using parallel subagents. Supports GitHub, GitLab, and enterprise platforms.

receiving-code-reviewskills/receiving-code-review/SKILL.md

Use when review findings arrive — verify each claim against the codebase and HOTL contracts before making changes. Governs how agents respond to review feedback.

requesting-code-reviewskills/requesting-code-review/SKILL.md

Use at executor review checkpoints to dispatch the code-reviewer agent with structured context — git range, workflow contracts, and verification evidence.

resumingskills/resuming/SKILL.md

Resume an interrupted workflow run with verify-first strategy — loads sidecar state, verifies the last step, and continues execution.

setup-projectskills/setup-project/SKILL.md

Use to generate HOTL adapter files for the current project — creates AGENTS.md, .clinerules, cursor rules, or copilot instructions depending on tools the team uses.

skill-authoringskills/skill-authoring/SKILL.md

Use when creating, editing, or reviewing HOTL skills, agents, command prompts, or other behavior-shaping instruction files.

subagent-executionskills/subagent-execution/SKILL.md

Delegated step runner over the HOTL execution state machine — delegates eligible steps to fresh subagents while the controller keeps governance, verification, and stop conditions.

systematic-debuggingskills/systematic-debugging/SKILL.md

Use when encountering any bug, test failure, or unexpected behavior — before proposing fixes.

tddskills/tdd/SKILL.md

Use before writing any implementation code — enforces RED-GREEN-REFACTOR cycle.

using-hotlskills/using-hotl/SKILL.md

Use when the user explicitly asks for HOTL routing or needs guidance choosing the right HOTL workflow skill.

verification-before-completionskills/verification-before-completion/SKILL.md

Use before claiming any work is complete, fixed, or passing — runs verification commands and confirms output before making success claims.

writing-plansskills/writing-plans/SKILL.md

Use after design approval to create a dated executable workflow file with bite-sized tasks, exact file paths, and loop/gate definitions.
