table-system-migration

table-system-migration is a skill for Claude Code, Codex from bogdanbaciu21/skills. It costs 88 tokens per session (2,194 once invoked), scanned A, original, MIT.

A workflow for replacing scattered HTML table styles across websites with one shared table design, while checking older tables and admin screens.

In plain words
What is it for?
Use it to review existing tables, move them to a standard component, preserve older table behavior, and test content pages, documentation, blogs, and admin grids.
Why use it?
It reduces inconsistent layouts and makes it harder for new table mistakes to be introduced. Browser-based checks help catch visual problems after the migration.

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

table-system-migration scanned grade A with 0 findings 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 4d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (table-ratchet.py, tests/test_table_ratchet.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Table System Migration

Overview

Use this skill to turn a messy estate of one-off HTML tables into a durable table system: a canonical component, compatibility rules for legacy/admin surfaces, a ratcheting linter, and real-browser layout regression tests.

Confidentiality Gate

Before writing or publishing any reusable output, scrub it as if the target repository is public.

  • Do not include local absolute paths, private repo names, production domains, customer names, emails, usernames, hostnames, tokens, passwords, keys, analytics IDs, database credentials, or commit hashes.
  • Do not paste private source files, proprietary copy, unreleased content, exact defect counts, or internal incident details into the skill or writeup.
  • Generalize examples. Prefer "content site", "admin grid", "canonical table class", and "legacy table class" over project-specific names.
  • If the user explicitly wants project-specific wording, keep it in the private repo or ask before staging it in a public skills repo.
  • Run a secret/string scan on the final diff before staging. Treat suspicious matches as blockers until explained or removed.

Workflow

1. Map The Table Estate

Inspect the repository before editing.

  • Identify content directories, templates/components, CSS entry points, generated assets, test commands, and CI gates.
  • Inventory table markup patterns: canonical classes, legacy classes, wrapper classes, naked <table> elements, per-page <style> blocks, captions, footnotes, scroll wrappers, numeric cells, total rows, and admin/data-grid tables.
  • Separate user-facing content tables from operational/admin grids. They may share CSS selectors but often need different layout behavior.
  • Note existing failures or intentional baseline debt. Do not promise a full cleanup if the requested task is only a ratchet or migration of priority surfaces.

2. Define The Canonical System

Specify the smallest table API that covers the real use cases.

  • Choose one canonical table class and one canonical wrapper class.
  • Define header, body, numeric, label, total-row, caption, source, footnote, methodology/detail, grouped-header, and horizontal-scroll behavior only when each is actually needed.
  • Preserve a compatibility layer for legacy/admin table classes if removing them would widen the blast radius.
  • Avoid one-off per-post or per-page table classes unless they encode a genuinely distinct component.

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.
