Grades are a hygiene check, not a security guarantee.

Claude Code, Skill

TaxClaw

Turn tax documents (W-2, 1099-NEC/INT/DIV/B/MISC/OID/R/G/K, 1099-DA, K-1, consolidated 1099s; PDF or image) into structured JSON/CSV for accountants and tax software, locally by default.

Compatibility: Not stated.

Grade C

One Medium finding. Read the report before installing.

Graded by PlugVetRubric v2

Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.

INSTALL_REMOTE_SCRIPT

Why this grade

  • INSTALL_REMOTE_SCRIPT Medium

    Fetches a script from the network and runs it (a pipe to a shell, or an install hook with a URL).

    src/doctor.py, line 178 f"`brew install ollama`; on Linux run `{install.get('linux', 'curl -fsSL https://ollama.com/install.sh | sh')}`. "

Any High, or two or more Medium findings, give D. One Medium gives C. Low findings or a security Note give B. Each code names a finding behind the letter.

Grades are a hygiene check of the source at the commit shown, on the date checked, not a security audit or a guarantee. The free directory grades are automated. Before release, a PlugVet engineer reviews every paid report and any grade we hold back, including all F grades, against the source code and the evidence we quote.

What was checked

Plain notes from the hygiene checks.

  • Permissions

    Concern

    can delete files.

    PERMISSION_DELETE_FILES

    benchmarks/taxclaw_accuracy/runner.py, line 52

    return subprocess.check_output(["git", "rev-parse", "HEAD"], cwd=ROOT,

    benchmarks/taxclaw_accuracy/runner.py, line 71

    proc = subprocess.run(cmd, input=json.dumps(request) + "\n", text=True,

    scripts/smoke.sh, line 380

    tracked = subprocess.run(["git", "-C", str(root), "ls-files"], capture_output=True, text=True, check=True).stdout.split()

    ignored = subprocess.run(["git", "-C", str(root), "check-ignore", "-q", "--no-index", rel]).returncode == 0

    src/store.py, line 577

    os.remove(file_path)

  • Install and update

    Serious

    install fetches a script from the network.

    INSTALL_REMOTE_SCRIPT

    README.md, line 66

    `brew install ollama`; Linux `curl -fsSL https://ollama.com/install.sh | sh`).

    src/doctor.py, line 178

    f"`brew install ollama`; on Linux run `{install.get('linux', 'curl -fsSL https://ollama.com/install.sh | sh')}`. "

    src/model_catalog.yaml, line 142

    linux: "curl -fsSL https://ollama.com/install.sh | sh"

  • Network

    Concern

    can reach a host that is not written as a fixed address.

    NETWORK_NO_FIXED_HOST

    templates/dashboard.html, line 182

    const r = await fetch('/api/stats', { headers: { 'Accept': 'application/json' } });

    templates/detail.html, line 425

    const resp = await fetch(`/doc/${encodeURIComponent(docId)}/fields/${encodeURIComponent(fieldPath)}`, {

  • Secrets

    Concern

    reads a credential or environment file.

    SECRETS_ENV_READ SECRETS_PATH_UNCONFIRMED

    src/config.py, line 207

    cfg.cloud_api_key = os.environ.get("ANTHROPIC_API_KEY", "")

    key = (cfg.cloud_api_key if cfg else "") or os.environ.get("ANTHROPIC_API_KEY", "")

    src/models.py, line 222

    key = os.environ.get("OPENAI_API_KEY", "")

    src/models.py, line 227
