julie: Skill for Claude Code

.agents/skills/editing/SKILL.md

editing is a skill for Claude Code from anortham/julie. It costs 62 tokens per session (1,125 once invoked), scanned A, original, MIT.

A guide for editing existing project files with Julie's code-editing tools, including changing text, rewriting symbols, and renaming symbols.

In plain words
What is it for?
Use it to modify existing files, change a function or class, rename a symbol across the workspace, or make targeted text replacements.
Why use it?
It directs edits through tools that can target code structure or fuzzy-matched text, avoiding unnecessary read-and-edit loops.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: installed under .agents/ (shared by several agents).

This is anortham/julie's own configuration. It tells Claude Code how to work on julie 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 julie configures →

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

editing 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.

How it starts

The opening of the file, as written. The whole thing — 87 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Editing Files with Julie

Julie's edit tools change existing files without reading them first. This is the default path for file modifications.

Which tool do I use?

  • Creating a new file? Use the Write tool. This skill doesn't apply.
  • Renaming a symbol across the workspace? Use rename_symbol, the semantic path. It understands scope, updates references, and surfaces conflicts.
  • Changing one symbol (function, struct, class, method)? Use deep_dive to understand it, then rewrite_symbol to change it.
  • Changing arbitrary text in a file? Use edit_file with old_text and new_text.
  • Need to understand the file first? Use get_symbols for structure or deep_dive for full context, then use rewrite_symbol. Not Read.

Stop and check

If you catch yourself thinking any of these, you're about to waste tokens:

Thought What to do instead
"I need to read the file first" No. edit_file uses DMP fuzzy matching on old_text. rewrite_symbol resolves a symbol by name. Neither needs Read.
"It's a quick change" edit_file handles that well. edit_file(old_text=..., new_text=..., dry_run=true) is the fast path.
"I'm not sure which symbol I need" Use fast_search, get_symbols, or deep_dive, then use rewrite_symbol. Still no Read + Edit loop.
"This isn't a code file" edit_file works on ANY text file: YAML, TOML, Markdown, .gitignore, configs, everything.
"The symbol edit is complex" Use dry_run=true first. If the symbol shape or operation does not fit, fall back to edit_file.

Workflow

  1. Always preview first: dry_run=true (the default). Review the diff.
  2. Then apply: same call with dry_run=false.

rewrite_symbol (for code symbols)

  • replace_full swaps an entire symbol definition
  • replace_body rewrites only the body
  • replace_signature rewrites only the signature
  • insert_before adds content before the symbol
  • insert_after adds content after the symbol
  • add_doc adds a doc block ahead of the symbol
  • file_path narrows the match when multiple symbols share a name

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
