using-hotl

using-hotl is a skill for Claude Code, Codex from yimwoo/hotl-plugin. It costs 25 tokens per session (879 once invoked), scanned A, original, MIT.

A guide for choosing HOTL workflow skills, where HOTL is a process for planning and carrying out code changes. It distinguishes quick questions and fixes from bugs, new features, and larger refactors.

In plain words
What is it for?
Routing feature work, major refactors, architectural changes, bug investigations, and test failures to the relevant HOTL workflow skills.
Why use it?
It helps developers select an appropriate workflow instead of using a lengthy planning process for every task. It also points bug investigations toward systematic debugging.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

using-hotl scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

When to Use HOTL Skills

HOTL skills are for code-changing tasks that require planning — new features, refactors, and significant changes. Not every task needs a skill.

Answer directly without invoking a skill:

  • Code understanding questions — "how does this work?", "where is this defined?", "explain this error"
  • Quick fixes — typos, config values, import paths, obvious one-line corrections
  • Error tracing — "what does this error mean?", "which file throws this?"

Use hotl:systematic-debugging (no brainstorm/plan needed):

  • Bug investigations, test failures, unexpected behavior

Use the full HOTL workflow (brainstorm → plan → execute):

  • New features, significant refactors, architectural changes

Available HOTL Skills

Invoke any of these when appropriate:

Skill When to Use
hotl:brainstorming Before any feature work — design with HOTL contracts
hotl:writing-plans After design approval — produces docs/plans/YYYY-MM-DD-<slug>-workflow.md
hotl:governed-execution Preferred execution entry point — selects host driver/profile while preserving renewable ownership, bounded loops, effect evidence, and receipts
hotl:executing-plans Linear execution with human checkpoints
hotl:loop-execution Execute a workflow file with loops + auto-approve
hotl:subagent-execution Delegated step runner over the loop execution engine — delegates eligible steps to fresh subagents
hotl:dispatch-agents 2+ independent tasks that can run in parallel
hotl:finishing-a-development-branch After execution — merge back, publish/PR, keep, or discard the execution branch/worktree
hotl:tdd Before writing any implementation code
hotl:systematic-debugging When encountering any bug or unexpected behavior
hotl:skill-authoring When creating, editing, or reviewing HOTL skills, agents, commands, or behavior-shaping instructions
hotl:document-review Optional — review existing docs, external specs, or hand-authored plans
hotl:requesting-code-review Dispatched by executors at review checkpoints — standardizes what context the reviewer receives
hotl:receiving-code-review Invoked when review findings arrive — verify, evaluate against contracts, then implement
hotl:code-review After completing implementation, before merging
hotl:pr-reviewing Review a PR across multiple dimensions — description, code, scan, tests
hotl:resuming Resume an interrupted workflow run with verify-first effect recovery and explicit ownership takeover/handoff
hotl:verification-before-completion Before claiming work is done
hotl:setup-project To generate adapter files for Codex, Cline, Cursor, Copilot

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
