txtify: Skill for Claude Code

.claude/skills/verify/SKILL.md

verify is a skill for Claude Code from lkmeta/txtify. It costs 54 tokens per session (600 once invoked), scanned A, original, Apache-2.0.

A project verification guide for checking software changes from tests through a full Docker run. Docker is a tool that packages an application and its environment so it can be tested consistently.

In plain words
What is it for?
Use it to run unit and API tests for focused changes, or a Docker end-to-end test that checks the application, uploads, transcription, previews, downloads, and validation errors.
Why use it?
It helps catch breakages after changes, especially in transcription, worker, dependency, or container files.

Skill for Claude Code

Written for Claude Code: installed under .claude/.

This is lkmeta/txtify's own configuration. It tells Claude Code how to work on txtify itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything txtify configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is ./scripts/docker_e2e.sh.

Reuse

Borrowing it

Nothing to install: this file belongs to lkmeta/txtify. Take a copy, put it at the same path in your own repository, and replace the rules that are about this project with yours.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

verify scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 46 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Verifying Txtify changes

Two tiers. Pick the cheapest one that actually exercises the change.

Tier 1 — unit/API tests (seconds, no ML stack needed)

pytest -q

Covers: format converters (incl. PDF Unicode round-trip), filename/URL/upload validation, job-id DB flow, /health, /transcribe error paths, DeepL alignment edge cases. tests/conftest.py stubs torch/stable_whisper when absent, so a light venv is enough:

grep -v -E '^(torch|stable-ts)' requirements.txt > /tmp/reqs.txt
pip install -r /tmp/reqs.txt pytest httpx pypdf

Sufficient on its own only for changes fully covered by tests (converters, validation, endpoint logic).

Tier 2 — Docker E2E (the real gate, ~5–10 min)

./scripts/docker_e2e.sh

Builds the image, boots a container, checks /health + all pages + 404s, uploads a generated clip, runs a real whisper-tiny transcription to 100%, validates preview in all four formats, downloads the zip and confirms the PDF is in it, and checks validation errors. Success is the literal line PASS: docker E2E complete.

Mandatory for changes to: requirements.txt, Dockerfile, .dockerignore, src/transcribe_process.py, src/models.py, the worker-spawn path in src/utils.py.

Reading failures

  • Status stuck at 10% → worker crashed at import (classic cause: an incompatible torch/torchaudio pair). Reproduce inside the container: docker exec <name> python /app/src/transcribe_process.py 99 output/<clip> en whisper_tiny none en all
  • Status stuck at 30% for a long time → model download in progress; not a failure yet.
  • Job errors mid-run → docker exec <name> cat output/<job id>_logs.txt (the server log won't show worker errors).
  • The E2E script's container is removed on exit; to debug interactively, docker run -d --rm --name txtify_dbg -p 8078:8011 txtify:e2e and drive it with curl.

What "verified" means in a PR body

Paste the actual output: the pytest summary line and/or the PASS: docker E2E complete line. A claim without output doesn't count.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

verify is a skill published in the GitHub repository lkmeta/txtify (135 stars, last pushed today), licensed Apache-2.0. It adds 54 tokens to every session and 600 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
