What it does

Segment Create is an agent skill from JanDeDobbeleer/oh-my-posh. Full scaffolding workflow for creating a new Oh My Posh segment. Invoke when asked to add a new segment: generates the Go source, registers the type, creates documentation, updates the sidebar and JSON schema.

Its SKILL.md is about 1.2k 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 Development, covering Project scaffolding. It works with Bash. The repository describes itself as: The most customisable and low-latency cross platform/shell prompt renderer. The licence is MIT.

When your agent uses it

Tasks that involve Project scaffolding

Example prompts

“/segment-create”

What it can do on your machine

Read from SKILL.md and the folder at commit 1d6bd96. 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
Shell commands in SKILL.md call:
- go
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

Segment Create loads about 1.2k tokens when it runs. Until then it costs about 56 tokens; SKILL.md has 375 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~56
When it runs · the whole SKILL.md, loaded when a task matches: ~1.2k

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.

name: segment-create
description: Full scaffolding workflow for creating a new Oh My Posh segment. Invoke when asked to add a new segment: generates the Go source, registers the type, creates documentation, updates the sidebar and JSON schema.

Segment scaffolding instructions

Goal

Given user inputs (segment id, Go type name, title, category, description, properties, template), generate all required code and docs to add a new segment end-to-end, following repo conventions.

Inputs

id: kebab/slug used as type and docs filename (e.g., new)
goType: PascalCase name for the Go struct (e.g., New)
title: human readable (e.g., New)
category: one of cli|cloud|health|languages|music|scm|system|web
description: one-line description
properties: list of { key, type, title, description, default }
template: default template string (e.g., {{.Text}})

Contract

Idempotent: do not duplicate registrations, constants, map entries, sidebar links, or schema entries.
Alphabetical insertions where applicable.
Compile-ready Go code, formatted.
Docs lint clean according to the markdown skill (.agents/skills/markdown/SKILL.md).

Implementation steps

Create Go writer file: src/segments/<id>.go

If file exists, skip creation.
Use this template; include property consts for each property key.

package segments

import (
    "github.com/jandedobbeleer/oh-my-posh/src/segments/options"
    "github.com/jandedobbeleer/oh-my-posh/src/runtime"
)

type {{goType}} struct {
    Base

    // computed fields used in template
    Text string
}

// properties
const (
{{#each properties}}
    // {{this.title}}: {{this.description}}
    {{ pascalCase this.key }} options.Property = "{{this.key}}"
{{/each}})

func (s *{{goType}}) Enabled() bool {
    // set up data for the template, using defaults from properties
    {{#if (propExists properties "text")}}
    s.Text = s.props.GetString({{ pascalCase "text" }}, {{ defaultFor "text" }})
    {{else}}
    s.Text = s.props.GetString({{ pascalCase (firstKey properties) }}, "")
    {{/if}}
    return true
}

func (s *{{goType}}) Template() string {
    return {{ printf "%q" template }}
}

Ensure in init() there is gob.Register(&segments.{{goType}}{}) exactly once.
Add constant: {{ upper id }} SegmentType = "{{id}}" in the alphabetical block.
Add to var Segments = map[SegmentType]func() SegmentWriter{} with key {{ upper id }} mapping to &segments.{{goType}}{}.
Keep lists alphabetically sorted. If not sorted, insert at correct position.

Documentation file

Consult the segment-docs skill (.agents/skills/segment-docs/SKILL.md) for the Go-to-documentation type mapping and rules for extracting options and template properties.
Path: website/docs/segments/{{category}}/{{id}}.mdx.
If file exists, skip. Else create with this template:

mdx

---
id: {{id}}
title: {{title}}
sidebar_label: {{title}}
---

## What

{{description}}

## Sample Configuration

import Config from '@site/src/components/Config.js';

<Config data={{
  "type": "{{id}}",
  "style": "powerline",
  "powerline_symbol": "\uE0B0",
  "foreground": "#193549",
  "background": "#ffeb3b",
  "options": {
{{#each option}}
    "{{this.key}}": {{ json this.default }},
{{/each}}
  }
}}/>

## Options

| Name | Type | Description | Default |
| ---- | ---- | ----------- | ------- |
{{#each option}}| `{{this.key}}` | `{{this.type}}` | {{this.description}} | `{{ stringify this.default }}` |
{{/each}}

Sidebar

Update website/sidebars.js under the correct category array to include "segments/{{category}}/{{id}}".
Insert alphabetically; if already present, do nothing.

Show full SKILL.md (146 more words)Show less

JSON Schema

File: themes/schema.json.
Add "{{id}}" to #/definitions/segment/properties/type/enum if missing.
Add an allOf entry for this segment guarded by { properties: { type: { const: "{{id}}" } } } that declares each property as defined by inputs. Use appropriate JSON Schema types and include title, description, default.
Keep the allOf array in a stable order by type name if feasible; otherwise append if not present.

Validation

After changes, run go build (task: build oh-my-posh). Ensure no compile errors.
Check markdown formatting; respect 120-char line length and fenced blocks with language.

Notes

Use UTF-32 escapes (e.g., "\uEFF1") for icon defaults in docs and code.
Keep code minimal. Complex logic should be added by maintainers after scaffold if needed.

Optional

Tests

Create a minimal test file at src/segments/{{id}}_test.go using the table-driven style. Include at least a happy-path test that asserts Enabled() returns true and the template renders expected output with default options.
