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

analyze-context 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 1mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/preprocess.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 1,076 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Analyze Context

Upload your existing files (docs, PDFs, code) and let SubAgents extract structured insights. Results are saved as clean documents - not dumped into chat context.


Purpose

Help users upload context that informs:

  • Goal refinement
  • Workspace structure suggestions
  • BUILD ideas
  • Integration opportunities

Key Principle:

  • 01-memory/input/ is TEMPORARY - holds uploads until organized
  • SubAgents write to 01-memory/input/_analysis/ (also temporary)
  • The "Organize Initial Context" BUILD distributes everything to 04-workspace/
  • After organization, 01-memory/input/ gets cleaned up

Pre-Execution

Create folders:

mkdir -p 01-memory/input/           # Where user uploads files (temporary)
mkdir -p 01-memory/input/_analysis/ # Where analysis results go (temporary)

Workflow

Step 1: Explain & Invite Upload

Display:

CONTEXT UPLOAD
----------------------------------------------------

Have files that show what you work on?

I'll analyze them and extract:
  - What you do (role, domain)
  - Patterns in your work
  - Tools you use (integration opportunities)
  - Ideas for what to build

Upload to:
→ 01-memory/input/

Supported:
  - PDFs (text extraction automatic)
  - Word docs (.docx)
  - Text files (.txt, .md)
  - Images (.png, .jpg - for screenshots)
  - Code files

When done, type 'done'.

Wait for user to upload and confirm "done"


Step 2: Scan & Validate Files

Use Glob tool to scan 01-memory/input/*:

from pathlib import Path

input_dir = Path("01-memory/input/")
uploaded_files = [f for f in input_dir.glob("*") if f.is_file()]

if not uploaded_files:
    print("No files found in 01-memory/input/")
    print("Please upload files and type 'done' when ready.")
    return

# Calculate total size
total_kb = sum(f.stat().st_size for f in uploaded_files) / 1024
file_count = len(uploaded_files)

print(f"Found {file_count} files ({total_kb:.1f} KB)")

Step 3: Pre-Processing (Extract & Normalize)

Files

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.
