re_workflow

Reverse-engineer EXE encryption to unlock XP3 archive schemes using Ghidra, Rizin, x64dbg, or IDA. Follow a step-by-step playbook for Galgame script extraction.

Instructions

TDQS

C2.8/5.0
Behavior1/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of disclosing behavioral traits. It does not mention whether the tool is read-only, whether it modifies files, how long it might take, whether it requires specific permissions, or what the output looks like. The term 'playbook' suggests orchestrating multiple operations, but no details about side effects or dependencies are given, making this a significant gap.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely concise, with a single sentence and no filler. The 'Playbook:' prefix is a bit cryptic but does not waste words. It is appropriately sized for a tool with no parameters, though it might benefit from slightly more detail to be more useful.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's apparent complexity (a multi-tool orchestration workflow), the description is quite incomplete. It does not explain the sequence of steps, expected outputs, or how it integrates with sibling re_* and xp3_* tools. There is no output schema and no further documentation, so the agent cannot accurately predict what this tool will do.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has zero parameters, so the parameter semantics baseline is 4. The description adds nothing about parameters, but there is nothing to explain. Schema coverage is trivially 100% and no parameter details are needed.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific goal: 'drive Ghidra/Rizin/x64dbg/IDA for EXE crypto → XP3 scheme.' This clearly identifies the tool as a playbook/workflow for reverse engineering EXE encryption to derive an XP3 scheme, distinguishing it from single-tool siblings like re_rizin or xp3_re_xor_recover. However, it does not explicitly define the scope of actions or how it orchestrates the listed tools, leaving some ambiguity about what the playbook actually does.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No explicit guidance is provided on when to use this tool versus alternatives. It does not mention any exclusions or recommend it for specific scenarios beyond the implied purpose of analyzing EXE crypto to identify an XP3 scheme. Sibling tools exist for more focused operations, but the description does not address when to choose this playbook over them.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
