Wire a country-specific income or expense stream into the MD money system: calculation block, hidden tooltip idea, loc key, and granting effect.

  • Works in 4 steps: Calculation → Hidden idea → Localisation → …
  • Asked to add an income

What it does

Additional Income is an agent skill from MillenniumDawn/Millennium-Dawn. Wire a country-specific income or expense stream into the MD money system: calculation block, hidden tooltip idea, loc key, and granting effect. Use when asked to add an income or expense stream, e.g. "/additional-income GRE goldenvisa income".

Its SKILL.md is about 660 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: Millennium Dawn and it's codebase. The licence is CC-BY-SA-4.0.

When your agent uses it

  • Asked to add an income

Example prompts

  • “/additional-income GRE goldenvisa income”
  • “/additional-income”

Workflow steps

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

  1. Calculation
  2. Hidden idea
  3. Localisation
  4. Grant the idea

What it can do on your machine

Read from SKILL.md and the folder at commit 5abce3e. 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

Additional Income loads about 664 tokens when it runs. Until then it costs about 66 tokens; SKILL.md has 203 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~66
When it runs · the whole SKILL.md, loaded when a task matches
~664

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.

description
Wire a country-specific income or expense stream into the MD money system: calculation block, hidden tooltip idea, loc key, and granting effect. Use when asked to add an income or expense stream, e.g. "/additional-income GRE golden_visa income".

Arguments: $ARGUMENTS, as TAG stream_name [income|expense]. Ask for anything missing. Also ask what activates the stream (focus, idea, flag), whether it is GDP-scaled or flat, its display name, and which focus, decision, or event grants it.

A stream needs four pieces. The variable name must match across all of them. For working examples, grep calculate_additional_income_rate in common/scripted_effects/.

1. Calculation

In common/scripted_effects/00_money_system.txt, inside calculate_additional_income_rate or calculate_additional_expense_rate:

if = {
    limit = { original_tag = TAG }
    if = {
        limit = { has_completed_focus = TAG_focus_name }
        set_variable = { TAG_stream_name_income = gdp_total }
        multiply_variable = { TAG_stream_name_income = 0.003 }
        add_to_variable = { additional_income_rate = TAG_stream_name_income }
    }
}
  • Income adds to additional_income_rate. Expense uses a _expense variable and adds to additional_expenses_rate.
  • Each country has one original_tag wrapper per effect. If one exists, nest the new inner if in it. Never add a second wrapper.
  • The value is GDP-scaled as above, or flat: set_variable = { TAG_x_income = 0.500 }.

2. Hidden idea

In the country's idea file, in its hidden_ideas block (add the block if missing):

hidden_ideas = {
    TAG_stream_name_money = {
        allowed_civil_war = { always = yes }
        modifier = {
            custom_modifier_tooltip = additional_income_TAG_stream_name_TT
        }
    }
}

Use additional_expense_TAG_stream_name_TT for an expense. Do not add allowed = { always = no } or an empty on_add.

3. Localisation

In localisation/english/MD_money_l_english.yml, beside the existing entries:

 additional_income_TAG_stream_name_TT: "$$[?TAG_stream_name_income|+3] from §YDisplay Name§!\n"
 additional_expense_TAG_stream_name_TT: "$$[?TAG_stream_name_expense|-3] from §YDisplay Name§!\n"

|+3 formats income and |-3 formats an expense. Keep the trailing \n.

4. Grant the idea

In the effect that unlocks the stream:

add_ideas = TAG_stream_name_money

Add remove_ideas = TAG_stream_name_money wherever the stream should stop.

Report

Summarize what was added. Remind the user to check in game that the tooltip appears and the value updates.
