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

edit-table 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 7d ago.

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.

The opening of the file, as written. The whole thing — 95 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Edit Table Skill

Use this skill when editing markdown tables with the edit tool. Prefer the table-specific modes over replace_by_lines — they are faster and use fewer tokens, especially for large tables (more than 20 rows).

When to use

  • Add, update, or remove a column in an existing table.
  • The table spans many rows and rewriting the whole table would be wasteful.
  • You already know the table's line range (fromLinetoLine) in the note.

For small, non-tabular edits inside a table row, replace_by_lines may still be appropriate — but column operations should use the modes below.

Shared parameters

All table modes require:

Field Description
path Path of the existing note containing the table.
fromLine Starting line (0-based) of the table in the note.
toLine Ending line (0-based) of the table in the note.

Use content_reading first if you need to locate the table or confirm line numbers.

Modes

add_table_column

Add a new column to the table.

Extra fields:

Field Description
content New column in Markdown: header, separator (---), then one value per data row (newline-separated). Example: Status\n---\nPending\nDone
insertAfter Optional. Column header name to insert after.
insertBefore Optional. Column header name to insert before.
(placement) If both insertAfter and insertBefore are omitted, the column is added at the end.

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.
