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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00020 | $0.01165 |
| Opus 5 | $0.00010 | $0.00583 |
| Sonnet 5 | $0.00004 | $0.00233 |
| Haiku 4.5 | $0.00002 | $0.00117 |
Grade A, and why
aida-audit-rce-analysis scanned grade A with 1 finding 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 9d 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.
Unrestricted tool accesslowExcessive agency
A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.
- **Remote Code Execution (RCE)**: The ability for an attacker to execute arbitrary commands or code on the target machine. Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

AIDA MCP RCE Analysis Skill Guide
This document guides agents on how to use the AIDA MCP toolset to audit Remote Code Execution (RCE) findings. It focuses on specific CWEs related to arbitrary code execution, including Command Injection, Buffer Overflows, and Unsafe Deserialization.
1. Core Concepts
- Remote Code Execution (RCE): The ability for an attacker to execute arbitrary commands or code on the target machine.
- CWE-78 (OS Command Injection): Improper neutralization of special elements used in an OS command.
- CWE-120/121/122 (Buffer Overflow): Copying data to a buffer without checking its size, potentially overwriting return addresses or function pointers.
- CWE-502 (Deserialization of Untrusted Data): The application deserializes untrusted data without sufficiently verifying that the resulting data will be valid.
- Sink-to-Source Analysis: The primary method for RCE auditing. Identify dangerous functions (sinks) and trace their arguments back to untrusted inputs (sources).
2. Skill Patterns
2.1 Command Injection Auditing (CWE-78)
Goal: Detect paths where user input flows into OS command execution APIs.
- Identify Sinks:
list_binary_imports(binary_name)- POSIX:
system,popen,exec,execl,execv,execle,execve,execvp. - Windows:
WinExec,ShellExecute,ShellExecuteEx,CreateProcess,CreateProcessA,CreateProcessW,_wsystem,_popen.
- POSIX:
- Locate Usage:
get_binary_cross_references(binary_name, address=SINK_ADDRESS) - Trace Argument Origin:
- Analyze the calling function:
get_binary_function_pseudocode_by_address(binary_name, addresses=FUNCTION_ADDRESS) - Identify the command string buffer.
- Trace backwards using
get_binary_function_callersif the buffer is passed as an argument.
- Analyze the calling function:
- Check Sanitization:
- Look for whitelisting or strict formatting (e.g., using
execvewith fixed arguments vssystemwith concatenated strings). - Flag any string concatenation involving input variables before the sink.
- Look for whitelisting or strict formatting (e.g., using
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.

aida-audit-rce-analysis is a skill published in the GitHub repository fire3/aida-audit (5 stars, last pushed 2mo ago), licensed MIT. It adds 20 tokens to every session and 1,165 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (unrestricted tool access). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
