What it does

Coding Plan is an agent skill from MagicCube/helixent. Enter "plan mode" for a coding task — read the relevant code, optionally ask clarifying questions, design one recommended approach, then write a plain, scannable plans/<prefix-<short-kebab-name.md file. No source files are edited in this mode. Use this skill whenever the user says "plan mode", "/coding-plan", "make a plan", "draft a plan first", "give me a plan before you code", "let's plan this out", "write a plan.md", "think before you code on this one", or otherwise asks for a written implementation plan to be…

Its SKILL.md is about 2.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows, covering Planning. The repository describes itself as: Helixent is a small library for building ReAct-style AI agent loops based on the Bun stack.

When your agent uses it

  • The user says plan mode
  • Draft a plan first
  • Give me a plan before you code
  • Lets plan this out

Example prompts

  • “plan mode”
  • “/coding-plan”
  • “make a plan”
  • “/coding-plan”

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Understanding
  2. Design
  3. Review
  4. Write plans/.md

What it can do on your machine

Read from SKILL.md and the folder at commit 5cc1fb3. 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

Coding Plan loads about 2.1k tokens when it runs. Until then it costs about 194 tokens; SKILL.md has 962 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~194
When it runs · the whole SKILL.md, loaded when a task matches
~2.1k

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 962 words (~2,119 tokens).

“A read-only, 4-phase workflow for coding tasks. Output is a single plans/.md file that a teammate can scan in 30 seconds before saying "go".”
