Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00047 | $0.01791 |
| Opus 5 | $0.00023 | $0.00896 |
| Sonnet 5 | $0.00009 | $0.00358 |
| Haiku 4.5 | $0.00005 | $0.00179 |
Grade C, and why
makefile scanned grade C with 1 finding 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 2d 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.
Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
rm -rf build/ How it starts
The opening of the file, as written. The whole thing — 324 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Rule Structure

Critical: Recipe lines MUST start with TAB character.
File vs Phony Targets
# File target - creates/updates a file
build/app.o: src/app.c
$(CC) -c $< -o $@
# Phony target - action, not a file
.PHONY: clean test install
clean:
rm -rf build/
Variable Assignment
| Operator | Name | When Expanded |
|---|---|---|
:= |
Simple | Once, at definition |
?= |
Conditional | If not already set |

Recursive | Each use (late binding) |
+= |
Append | Adds to existing value |
CC := gcc # Immediate
CFLAGS ?= -O2 # Default, overridable
DEBUG = $(VERBOSE) # Late binding
CFLAGS += -Wall # Append

What ships with it
7 files 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.
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.
- 2d ago First seen · 324 lines · 47 tokens per session scan C 2231bbf9b4d9
makefile is a skill published in the GitHub repository itechmeat/llm-code (22 stars, last pushed 1mo ago), licensed MIT. It adds 47 tokens to every session and 1,791 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
