At a glance

Guide to the console struct tag system in gh-aw: headers, titles, number and cost formats, omitempty, and how structs, slices and maps render in the terminal.

  • Adding console tags to a Go struct for terminal output in gh-aw
  • SKILL.md covers Struct Tag Support, Example Usage, Format Tag Examples and Rendering Behavior
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Rendering a slice of structs as a table

What it does

This guide explains how to control styled terminal output in gh-aw by tagging Go struct fields with console. The header option sets a field's display name for both structs and tables, title names the section for nested structs, slices or maps, format selects number (human-readable values like 1k or 1.2M) or cost (currency with a dollar prefix), omitempty skips zero values, and a dash always skips the field.

Rendering follows the data shape: a struct becomes aligned key-value pairs, a slice of structs becomes a table with one column per header, and a map becomes markdown-style headers with key-value pairs. time.Time fields print as a date and time string and count as empty under omitempty when zero, and unexported fields are skipped safely by checking CanInterface before reading them. Worked examples show an overview struct, a metrics struct with number formatting and a billing struct with cost formatting.

When your agent uses it

  • Adding console tags to a Go struct for terminal output in gh-aw
  • Rendering a slice of structs as a table
  • Formatting token counts or costs in CLI output

Example prompts

  • “Add console tags to this RunSummary struct so it prints as aligned key-value pairs.”
  • “Show the job list as a table with Name, Status and Conclusion columns.”
  • “Format TokenUsage as a human-readable number and Cost as currency.”

Requirements

  • The gh-aw Go codebase

What it can do on your machine

Read from SKILL.md and the folder at commit eb63040. 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 (its code samples are 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

gh-aw Console Rendering Tags loads about 736 tokens when it runs. Until then it costs about 20 tokens; SKILL.md has 174 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~20
When it runs · the whole SKILL.md, loaded when a task matches
~736

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.

Use Go struct tags to render styled terminal output in gh-aw.

Console Rendering System Usage

Use this guide for the struct tag-based console rendering system.

Struct Tag Support

Use the console struct tag to control rendering behavior:

  • header:"Name" - Sets the display name for fields (used in both structs and tables)
  • title:"Section Title" - Sets the title for nested structs, slices, or maps
  • format:"type" - Sets the formatting type for the field value
    • format:number - Formats integers as human-readable numbers (e.g., "1k", "1.2M")
    • format:cost - Formats floats as currency with $ prefix (e.g., "$1.234")
  • omitempty - Skips the field if it has a zero value
  • "-" - Always skips the field

Example Usage

go
type Overview struct {
    RunID    int64  `console:"header:Run ID"`
    Workflow string `console:"header:Workflow"`
    Status   string `console:"header:Status"`
    Duration string `console:"header:Duration,omitempty"`
}

data := Overview{
    RunID:    12345,
    Workflow: "test-workflow",
    Status:   "completed",
    Duration: "5m30s",
}

// Simple rendering
fmt.Print(console.RenderStruct(data))

// Output:
//   Run ID  : 12345
//   Workflow: test-workflow
//   Status  : completed
//   Duration: 5m30s

Format Tag Examples

Number Formatting
go
type Metrics struct {
    TokenUsage int `console:"header:Token Usage,format:number"`
    Errors     int `console:"header:Errors"`
}

data := Metrics{
    TokenUsage: 250000,
    Errors:     5,
}

// Renders as:
//   Token Usage: 250k
//   Errors     : 5
Cost Formatting
go
type Billing struct {
    Cost float64 `console:"header:Estimated Cost,format:cost"`
}

data := Billing{
    Cost: 1.234,
}

// Renders as:
//   Estimated Cost: $1.234

Rendering Behavior

Structs

Structs are rendered as key-value pairs with proper alignment.

Slices

Slices of structs are automatically rendered as tables:

go
type Job struct {
    Name       string `console:"header:Name"`
    Status     string `console:"header:Status"`
    Conclusion string `console:"header:Conclusion,omitempty"`
}

jobs := []Job{
    {Name: "build", Status: "completed", Conclusion: "success"},
    {Name: "test", Status: "in_progress", Conclusion: ""},
}

fmt.Print(console.RenderStruct(jobs))

Renders as:

Name  | Status      | Conclusion
----- | ----------- | ----------
build | completed   | success
test  | in_progress | -
Maps

Maps are rendered as markdown-style headers with key-value pairs.

Special Type Handling
time.Time

time.Time fields are automatically formatted as "2006-01-02 15:04:05". Zero time values are considered empty when used with omitempty.

Unexported Fields

The rendering system safely handles unexported struct fields by checking CanInterface() before attempting to access field values.
