mcp-cs: Skill for Claude Code

.agents/skills/algo-stress-testing/SKILL.md

algo-stress-testing is a skill for Claude Code, Codex from ieeecsopen/mcp-cs. It costs 245 tokens per session (8,387 once invoked), scanned A, original, no licence file.

A debugging aid for competitive-programming solutions that receive Wrong Answer or Time Limit Exceeded results on hidden tests.

In plain words
What is it for?
It is for stress-testing an algorithm against inputs that may expose incorrect results or solution-specific timeouts.
Why use it?
It helps investigate failures that appear only on particular inputs instead of guessing from the visible examples.

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing. Also seen: installed under .agents/ (shared by several agents).

This is ieeecsopen/mcp-cs's own configuration. It tells Claude Code and Codex how to work on mcp-cs itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything mcp-cs configures →

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

algo-stress-testing 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 2mo 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.

Runs shell commandslowCapability

Expected in a hook, worth knowing in a rule or an instructions file.

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.
