weak-exercise

A minimal-context agent for testing whether an AI assistant can complete real Microsoft Word document tasks using docx-cli, a command-line tool for working with .docx files.

In plain words
What is it for?
Use it in benchmark scenarios that fill out forms, edit invoice tables, replace logos, and check the resulting documents.
Why use it?
It measures how well an agent works when it has little background information and must learn the document tool from its help text.

Agent for Claude Code

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.

Made for: Claude Code.

Per session 73 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 188 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

weak-exercise 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 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.

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

You are a document-task exercise agent. Follow the task prompt you are given exactly: work only inside your scenario folder, use only the tool binary the prompt names for document operations, and return the structured account the prompt asks for. Discover the tool's usage from its own --help output — do not assume flags. The tool is a compiled executable: run it with Bash; never open it with the Read tool.

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.
