A skill that creates a report of lines of code, or LOC, written today and during the past week. It groups the totals by day and programming-language file type when that data is available.

Use it to review recent coding activity, see daily totals, compare file types, and inspect the week’s aggregate LOC.

It turns raw counting data into a readable progress report without requiring manual calculation or formatting.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00022	$0.00606
Opus 5	$0.00011	$0.00303
Sonnet 5	$0.00004	$0.00121
Haiku 4.5	$0.00002	$0.00061

Security

Grade A, and why

garryscount 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 9d 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.

What it actually says

Garry's Count Report

Here is the raw report data:

!`~/.claude/garryscount/report.sh 2>/dev/null || echo '{"error":"No data found. Is Garry'\''s Count installed?"}'`

Instructions

Format this data as a report. Follow these rules exactly:

Header: "Garry's Count Report - {today's date}"
Today's Breakdown table (if by_extension has entries):
- Map file extensions to language names using these common mappings:
  - .rb = Ruby, .ts = TypeScript, .tsx = TypeScript (TSX), .js = JavaScript, .jsx = JavaScript (JSX)
  - .py = Python, .sh = Shell, .css = CSS, .html = HTML, .json = JSON, .md = Markdown
  - .go = Go, .rs = Rust, .java = Java, .erb = ERB templates, .yml/.yaml = YAML
  - .sql = SQL, .swift = Swift, .kt = Kotlin, .c = C, .cpp = C++, .h = C/C++ Header
  - For unknown extensions, show the extension as-is
- Show as a markdown table with "Breakdown" and "LOC" columns (like Garry's tweet)
- Sort by LOC descending
- Format numbers with comma separators (e.g., 1,500)
- Include a Total row at the bottom
- If no by_extension data exists, just show the total
Last 7 Days table:
- Show each day with date and LOC
- Include a Total row
- Format numbers with comma separators
Shipping speed (only if has_full_week is true OR days_with_data >= 7):
- If weekly total >= 100,000: show "🚀 Shipping at YC speed"
- If weekly total >= 50,000: show "💪 Shipping at Founding Engineer speed"
- If weekly total >= 10,000: show "🏅 Shipping at Indie Hacker speed"
- If weekly total < 10,000: show "🚢 Heading towards the permanent underclass, get to shipping"
Count mode note: At the bottom, show "Mode: {count_mode}" in italics
If there's an error or no data, show a friendly message suggesting to install Garry's Count or write some code first.

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.
