When your agent uses it

  • Tasks that involve Tax preparation

Example prompts

  • “fondo R&D credit”
  • “fondo tax credit”
  • “fondo Form 6765”
  • “/fondo-core-workflow-b”

Requirements

  • Compatibility (from SKILL.md): Designed for Claude Code
  • Pre-approved tools (allowed-tools): Read, Write, Edit, Grep

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Gather approved source evidence and classify activities/expenses for review without altering originals.
  2. Use an opaque case identifier and aggregate counts for workflow tracking; keep payroll, tax, and employee records in authorized systems.
  3. Reconcile inputs with the responsible finance professional, document assumptions and exceptions, and obtain sign-off before filing or…
  4. Preserve an audit trail and follow the organization's retention and correction process for any discrepancy.

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Write
    • Edit
    • Grep

    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

    Links to these hosts (documentation or services it may open):

    • fondo.com
    • irs.gov

    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.

  • Compatibility

    Designed for Claude Code

    From compatibility in the SKILL.md frontmatter.

Context cost

Fondo Core Workflow B loads about 1.1k tokens when it runs. Until then it costs about 62 tokens; SKILL.md has 365 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~62
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

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.

Fondo Core Workflow B: R&D Tax Credits

Overview

Claim R&D tax credits through Fondo. Startups with US W-2 employees doing qualifying R&D can offset up to $500,000/year in payroll taxes (FICA). Fondo's CPA team prepares the Form 6765 study.

Prerequisites

  • An authorized finance/tax owner, current professional guidance, complete source records, and a retention/access policy.
  • A reviewed scope for any calculator or export; this workflow does not determine eligibility or replace tax advice.

Instructions

  1. Gather approved source evidence and classify activities/expenses for review without altering originals.
  2. Use an opaque case identifier and aggregate counts for workflow tracking; keep payroll, tax, and employee records in authorized systems.
  3. Reconcile inputs with the responsible finance professional, document assumptions and exceptions, and obtain sign-off before filing or payment actions.
  4. Preserve an audit trail and follow the organization's retention and correction process for any discrepancy.

Output

Create a review receipt with period, case ID, source-system references, owner, open questions, professional-review status, and next action. Do not include employee, payroll, tax-return, or bank details.

Examples

Use a fictional project and aggregate cost buckets to exercise the evidence-collection checklist. Record unresolved classification questions for the finance reviewer and confirm no filing, calculation, or payroll action is generated from the test.

R&D Credit Calculation

Qualifying R&D Expenses:
  W-2 wages for R&D employees:        $480,000
  Contractor payments (65%):           $78,000
  Cloud compute (AWS/GCP):             $36,000
  Software tools for R&D:              $12,000
                                       --------
  Total Qualified Research Expenses:   $606,000

Credit Rate (Alternative Simplified):  ~6-8%
Estimated R&D Credit:                  ~$42,000
