  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • Self-contained

    Everything the model needs lives in the instructions — no extra files to sync.

  • Open source

    Published by openaccountant on GitHub. Read the source before you install it.

Installation

Install the Depreciation Schedule AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
    https://github.com/openaccountant/skills/tree/main/shared/depreciation-schedule
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.
2

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/openaccountant/skills.git /tmp/skills
mkdir -p .claude/skills
cp -r /tmp/skills/shared/depreciation-schedule .claude/skills/depreciation-schedule
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Depreciation Schedule in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Depreciation Schedule on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Depreciation Schedule is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Depreciation Schedule

Overview

Tracks business asset purchases and calculates annual depreciation deductions using the Modified Accelerated Cost Recovery System (MACRS). Also covers Section 179 immediate expensing for qualifying assets. Reports to Schedule C, Line 13 via Form 4562.

Wilson Tools Used

  • transaction_search — Find asset purchases (equipment, furniture, vehicles, property)
  • categorize — Tag transactions as depreciable assets with their asset class
  • export_transactions — Export asset list and depreciation schedule for Form 4562

Workflow

  1. Use transaction_search to find large purchases that qualify as business assets (typically items with a useful life over 1 year).
  2. For each asset, determine:
    • Date placed in service
    • Cost basis (purchase price + sales tax + delivery/installation)
    • Asset class and recovery period (see table below)
  3. Decide whether to use Section 179 expensing, bonus depreciation, or regular MACRS.
  4. Calculate the annual depreciation for each asset.
  5. Use export_transactions to generate a depreciation schedule for Form 4562.

MACRS Recovery Periods

Recovery PeriodAsset ClassExamples
3-yearCertain tools, livestockTractor units, rented personal property
5-yearComputers, office equipmentLaptops, printers, copiers, automobiles, light trucks
7-yearOffice furniture, fixturesDesks, chairs, shelving, most machinery
15-yearLand improvementsParking lots, fences, landscaping
27.5-yearResidential rental propertyRental houses, apartments
39-yearCommercial real propertyOffice buildings, retail space, warehouses

MACRS Depreciation Rates (200% Declining Balance, Half-Year Convention)

5-Year Property:

YearRate
120.00%
232.00%
319.20%
411.52%

Section 179 Expensing

  • Allows you to deduct the full cost of qualifying assets in the year purchased, instead of depreciating over time.
  • 2025 limit: approximately $1,220,000 (adjusted annually for inflation; verify at irs.gov).
  • Phase-out begins when total asset purchases exceed approximately $3,050,000.
  • Cannot create a business loss -- deduction limited to net business income.
  • Applies to tangible personal property (equipment, furniture, vehicles), off-the-shelf software, and certain improvements to nonresidential real property.

Bonus Depreciation

  • 100% bonus depreciation expired after 2022. The rate phases down: 80% (2023), 60% (2024), 40% (2025), 20% (2026), 0% (2027+).
  • Applies to new and used property with a recovery period of 20 years or less.
  • Can create a business loss (unlike Section 179).

Without Wilson

  1. Create a spreadsheet with columns: Asset Description, Date Placed in Service, Cost Basis, Recovery Period, Method (179/MACRS/Bonus), Annual Depreciation.
  2. For each asset, look up the recovery period from the table above.
  3. For MACRS, multiply the cost basis by the applicable year's percentage rate.
  4. For Section 179, deduct the full cost in year 1 (up to the annual limit).
  5. For bonus depreciation, multiply cost basis by the applicable year's bonus rate.
  6. Sum all annual depreciation amounts. Enter the total on Schedule C, Line 13.
  7. File Form 4562 with your return listing each asset.

Important Notes

  • Land is never depreciable. When purchasing real property, allocate the cost between land and building.
  • Vehicles have additional depreciation limits (luxury auto caps). For 2025, the first-year limit for passenger automobiles is approximately $12,400 (verify annually).
  • If business use of an asset drops below 50%, you must recapture excess depreciation and switch to straight-line.
  • Keep purchase receipts and records of when each asset was placed in service.
  • Real property (27.5-year and 39-year) uses straight-line depreciation, not accelerated.
  • This is not tax advice. Consult a CPA or tax professional for filing decisions.

Frequently asked questions

What does the Depreciation Schedule AI skill do?

Track asset depreciation using MACRS schedules and Section 179 expensing.

Why use Depreciation Schedule on TypingMind?

Because you install it once and use it with any model. Depreciation Schedule is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Depreciation Schedule in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/openaccountant/skills/tree/main/shared/depreciation-schedule. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Depreciation Schedule?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Depreciation Schedule?

As many as you like. As long as a model supports skills, you can use Depreciation Schedule with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Depreciation Schedule AI skill free?

Yes. It is published on GitHub by openaccountant under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
