Human-readable status report for all tax forms. An agent skill from filedcom/opentax.

  • Works in 2 steps: Discover Forms → Print Report

  • SKILL.md covers Step 0 — Discover Forms and Step 1 — Print Report
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Tax Status is an agent skill from filedcom/opentax. Human-readable status report for all tax forms. Shows benchmark accuracy, active root causes, and build/fix state for each form:year.

Its SKILL.md is about 310 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 Root cause analysis. The repository describes itself as: Fully open-source US federal tax engine. Single binary cli. Runs on macOS, Linux, and Windows. Built for AI agents using AI agents. The licence is AGPL-3.0.

When your agent uses it

  • Tasks that involve Root cause analysis

Example prompts

  • “/tax-status”

Workflow steps

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

  1. Discover Forms
  2. Print Report

What it can do on your machine

Read from SKILL.md and the folder at commit 0c6ae76. 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

Tax Status loads about 314 tokens when it runs. Until then it costs about 36 tokens; SKILL.md has 63 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~36
When it runs · the whole SKILL.md, loaded when a task matches
~314

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.

Tax Status

Step 0 — Discover Forms

Glob forms/f*/FORM.md to enumerate all known forms. Read .state/bench/state.json. If it does not exist → print "Harness not initialized." and stop. Confirm version === 2. If version === 1 → print "State schema outdated. Run migration." and stop.

Step 1 — Print Report

For each entry in state.forms, print one section:

━━━ Tax Harness Status ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

{form}:{year} Fix
  Status:    {fix.status}
  Baseline:  {fix.benchmark_baseline.pass} pass / {fix.benchmark_baseline.fail} fail
  Progress:  ████████░░ {pct}%
  Root Causes:
    ✓ {name}  (fixed)
    ✗ {name}  (pending — cases {list})

{form}:{year} Build
  Status:    {build.status}
  Phase:     {build.phase}
  Cases:     {build.benchmark_cases_created} benchmark cases
  Nodes:     {build.nodes_built.length} nodes built
  Last run:  {last benchmark_runs entry}

━━━ Recent Activity ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

{last 5 entries from .state/bench/progress.md}

Use color: green for done/fixed, red for pending/failed, yellow for running.
