readme-edit

readme-edit is a skill for Claude Code, Codex from getkyo/kyo. It costs 58 tokens per session (1,365 once invoked), scanned A, original, Apache-2.0.

A mechanical README editor that applies an approved list of changes, such as cutting, moving, rewriting, or adding callouts.

In plain words
What is it for?
Use it to update a README from a prepared edit plan, including changing headings, reorganising sections, rewriting text, and removing em dashes by rewriting the sentence.
Why use it?
It removes the need to make each documented change by hand. It follows the supplied action list without re-evaluating the underlying findings.

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

readme-edit 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 6d 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.

/readme-edit: apply a structured action list to a README

The task is:

$ARGUMENTS

Inputs required:

  • readme_path: path to the README file to edit.
  • action_list: structured findings document produced by readme-analyze-existing, containing one or more entries of the types listed below.

This sub-skill is mechanical. The action list is already approved. Do not re-diagnose, re-evaluate, or second-guess entries. Apply every entry in the list, in order, unless an entry requests an addition that is NOT in the allowed list (see "Out-of-scope additions" below).


Action type semantics

Type What it means What to do
[CUT] Delete the line range entirely. Remove those lines. No replacement.
[RELOCATE] Move the line range to the target location specified in the entry. Cut from source; insert at target. Preserve the content verbatim.
[RESTRUCTURE] Replace the line range with the description-of-replacement in the entry. Synthesize replacement content from the entry's rationale and the existing README material. Do NOT invent new content beyond what the rationale describes.
[REWRITE-HEADING] Change heading text from current to proposed. Replace only the heading text. Keep the heading level (##, ###, etc.) unchanged.
[REORDER] Move the entire section (from the heading at from_line to just before the next ## heading at the same level) to immediately before the section at to_line. Relocate the whole section block as a unit.
[ADD-CALLOUT] Insert a callout paragraph at the specified location, sourced from the entry's source reference. Insert one or two sentences at the specified line. Content must come from the source reference named in the entry (scaladoc, test, implementation comment). Do not invent.

Em-dash rewriting (special case)

When the action list contains [CUT] entries on em-dashes, do NOT mechanically substitute ; or -. The fix is to REWRITE the sentence so the em-dash is not needed.

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.
