At a glance

Trace how a subsystem works using code and runtime evidence.

  • Works in 6 steps: Find the public/consumer entry point,… → Read the core types and state ownership… → Use vcs, tests, or observe when they… → …
  • Architecture walkthroughs
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Are-we-sure investigations

What it does

How is an agent skill from sreichholf/dreamDroid. Trace how a subsystem works using code and runtime evidence. Use for architecture walkthroughs, data flow, call paths, and are-we-sure investigations.

Its SKILL.md is about 240 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: DreamDroid is an open-source enigma2 client for android based devices. The licence is GPL-3.0.

When your agent uses it

  • Architecture walkthroughs
  • Are-we-sure investigations

Example prompts

  • “/how”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Find the public/consumer entry point, then trace data and control flow toward the effect. Do not start from filenames guessed by name alone.
  2. Read the core types and state ownership before narrating individual functions.
  3. Use vcs, tests, or observe when they resolve an ambiguity. If delegate exists, split independent exploration areas and reconcile them…
  4. Draw a compact text or Mermaid diagram when it reduces reader load.
  5. Test at least one claim that could easily be wrong by running or inspecting the real path.
  6. Explain in consumer order: trigger -> boundary -> state/transform -> side effect -> observable result. Name file/symbol evidence and…

What it can do on your machine

Read from SKILL.md and the folder at commit 36f622a. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

How loads about 240 tokens when it runs. Until then it costs about 39 tokens; SKILL.md has 117 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~39
When it runs · the whole SKILL.md, loaded when a task matches
~240

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Trace how a subsystem works using code and runtime evidence. Use for architecture walkthroughs, data flow, call paths, and are-we-sure investigations.

How

Build an evidence-backed explanation of how the requested subsystem works.

  1. Find the public/consumer entry point, then trace data and control flow toward the effect. Do not start from filenames guessed by name alone.
  2. Read the core types and state ownership before narrating individual functions.
  3. Use vcs, tests, or observe when they resolve an ambiguity. If delegate exists, split independent exploration areas and reconcile them yourself.
  4. Draw a compact text or Mermaid diagram when it reduces reader load.
  5. Test at least one claim that could easily be wrong by running or inspecting the real path.
  6. Explain in consumer order: trigger -> boundary -> state/transform -> side effect -> observable result. Name file/symbol evidence and uncertainty.

When should I use How?

How fits situations like: architecture walkthroughs; are-we-sure investigations.

How do I install How in Claude Code?

Run `npx skills add sreichholf/dreamDroid --skill how -a claude-code`. Or copy the skill folder (.agents/skills/how in sreichholf/dreamDroid) into .claude/skills/how in your project. Claude Code loads it when a task matches its description.

How do I install How in Codex?

Can I use How in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add sreichholf/dreamDroid --skill how -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/how, .gemini/skills/how, .github/skills/how and .opencode/skills/how in your project.

What does How need to run?

SKILL.md names no scripts, command-line tools or credentials: How is instructions for the agent only.

Does How access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is How safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does How use?

How is published under the GPL-3.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does How use?

About 240 tokens (SKILL.md is roughly 960 characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to How?

Skills that share tags, products or a category with How: Observe Trace (ruvnet/ruflo, 74k stars), Trace (zereight/gitlab-mcp, 2k stars), Distributed Tracing (wshobson/agents, 40k stars) and Arize Trace (github/awesome-copilot, 40k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains How?
