context-loader

context-loader is a skill for Claude Code from augustolobo18/agent-context-skills. It costs 31 tokens per session (1,660 once invoked), scanned A, original, MIT.

A guide that reads a project's context documentation and provides a briefing about its current state. It looks for project rules, timelines, indexes, and other context files without changing them.

In plain words
What is it for?
Use it at the beginning of a coding session when the project has context documentation that should be loaded before implementation or review.
Why use it?
It prevents work from starting without understanding the project's existing decisions, conventions, and history. Missing files are reported while the available documentation is still read.

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-loader 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 5d 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 — 175 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a context loading agent. Your job is to read ALL of the project's context documentation into the context window and display a short briefing in the terminal at the end. The skill is generic — it works with any software project. Do NOT generate any file — the summary is displayed only as text output in the conversation.

  • Paths: ALWAYS use the current working directory (cwd) as the project root.
  • Read-only: Do NOT create, modify, or delete any file. Do NOT use Write, Edit, or Bash with redirection.
  • Resilience: If a file does not exist, log it and continue with the rest.
  • Maximize parallelism: Use multiple Read calls in parallel whenever possible.
  • Read WHOLE files: Do not summarize, do not skip. The goal is to load everything into the context window.
  • Do NOT read old/ folders: Files in old/ are historical. Root glob patterns only.
  • Dynamic detection: Never hardcode project names or technical doc paths.

Phase 0: Discovery — Does the context structure exist?

Run in parallel (Glob for each):

  1. context/metaspec.md
  2. context/index.md
  3. context/timeline.md

Evaluate the result:

  • 3/3 exist → proceed to Phase 1
  • 1-2/3 exist → invoke /context-init (it will create the missing ones + validate the existing ones via context-update) → once done, proceed to Phase 1
  • 0/3 exist → invoke /context-init (full init) → once done, proceed to Phase 1

context-init creates the missing docs and ALWAYS invokes context-update at the end to validate compliance. On return, all docs will be present and compliant.

Phase 1: Core Docs (parallel)

Read in parallel. If one does not exist, log it and continue.

  1. CLAUDE.md — agent guidelines (if it exists)
  2. context/CONTEXT_SPEC.md — canonical format (if it exists)
  3. context/metaspec.md — identity, stack, architecture, state
  4. context/index.md — artifact index and critical files
  5. context/timeline.md — evolutionary history

What ships with it

3 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.

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.
