contextforge-cli: Skill for Claude Code

.agents/skills/context-selector/SKILL.md

context-selector is a skill for Claude Code, Codex from alejandro-cedeno-10/contextforge-cli. It costs 0 tokens per session (49 once invoked), scanned A, original, MIT.

A context-selection rule written in Spanish. It says to choose the smallest sufficient set of project information, starting with seed files and then adding their dependencies while respecting a token limit.

In plain words
What is it for?
Use it to select task-relevant files from a dependency graph, prioritise starting files and connected code, and control the amount of context supplied to the agent.
Why use it?
It helps an AI coding agent avoid loading unnecessary files and keeps its working context within a defined size.

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is alejandro-cedeno-10/contextforge-cli's own configuration. It tells Claude Code and Codex how to work on contextforge-cli 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 contextforge-cli 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

context-selector 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 2mo 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.

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.
