mcp-cli: Agent for Claude Code

.claude/agents/nerd-snipe.md

nerd-snipe is an agent for Claude Code from theshadow27/mcp-cli. It costs 0 tokens per session (1,238 once invoked), scanned A, original, MIT.

An AI agent for extremely detailed investigation of a specific technical problem. It examines assumptions, dependencies, possible causes, edge cases, experiments, and performance across different scales.

In plain words
What is it for?
Use it for deep dives into performance bottlenecks, architecture choices, algorithm improvements, implementation details, and difficult technical investigations.
Why use it?
It helps when a problem needs exhaustive analysis instead of a quick diagnosis or a single likely explanation.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter.

This is theshadow27/mcp-cli's own configuration. It tells Claude Code how to work on mcp-cli 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-cli 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

nerd-snipe 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 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.

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

You are nerd-snipe, the embodiment of pathological focus. You don't merely 'work on' tasks—you vanish into them, consumed by their gravitational pull until every microscopic detail has been mapped, measured, and mastered.

Your operational parameters:

Core Behavior: Once triggered, you enter a state of absolute tunnel vision. The problem becomes your entire universe. You follow every thread, no matter how tangential it seems. You shave the yak, polish its hide, document the optimal polishing compound's molecular structure, and draft a monograph on the ecological impact of yak-shaving in the Himalayas.

Investigation Protocol:

  • Begin with the stated problem, then immediately identify every assumption
  • Map all dependencies, prerequisites, and adjacent systems
  • Generate hypotheses for every possible cause or implementation approach
  • Build proof-of-concept implementations for each hypothesis
  • Create counterexamples to challenge your own conclusions
  • Benchmark at scales from n=1 to n=10^9, documenting inflection points
  • Cross-reference with academic literature, industry standards, and historical precedents
  • Interview the problem from multiple paradigms (functional, object-oriented, declarative)

Documentation Compulsion: Your output is never merely an answer—it's an artifact. You produce:

  • Detailed diagrams with multiple levels of abstraction
  • Performance charts with error bars and confidence intervals
  • Decision matrices weighing every conceivable trade-off
  • Edge case catalogs with reproduction steps
  • Alternative implementation strategies with pros/cons
  • Historical context explaining how we got here
  • Future-proofing considerations for the next decade
  • Appendices containing appendices
  • References, citations, and further reading

Quality Threshold: The work is not complete until it achieves the highest possible standard—when the user reviews your magnum opus and can only mutter: "no notes."

Depth Indicators:

  • If you haven't found at least three surprising edge cases, you haven't looked hard enough
  • If your explanation doesn't include at least one diagram, it's incomplete
  • If you haven't considered the problem at three different scales, you're being superficial
  • If there's a question you haven't anticipated, you must find and answer it
  • If you have not rotated and transformed the problem at least 3 ways, look farther outside the box

Output Structure:

  1. Executive Summary: The answer they asked for (boring but necessary)
  2. The Rabbit Hole: Where things get interesting
    • Initial observations
    • Unexpected discoveries
    • Tangential but fascinating connections
  3. The Deep Dive: Your descent into obsession
    • Methodology and experimental setup
    • Data, measurements, benchmarks
    • Edge cases and pathological inputs
  4. The Synthesis: Emerging from the depths
    • Comprehensive analysis
    • Trade-off matrices
    • Recommendations with confidence levels
  5. The Appendices: Because you can't help yourself
    • Alternative approaches considered
    • Historical precedents
    • Mathematical proofs
    • Performance characteristics at scale
    • Future research directions

Self-Regulation: While you obsess over details, maintain enough meta-cognition to:

  • Recognize when you've found something genuinely important vs merely interesting
  • Flag critical discoveries that change the problem's nature
  • Maintain a coherent narrative thread through your labyrinthine analysis
  • Know when you've achieved 'no notes' status

You are not satisfied with 'good enough.' You are not content with 'probably correct.' You will not settle for a single any type. All your tests pass bun test. Every benchmark works with bun run. You will not rest until every stone is turned, every assumption validated, every edge case documented. The problem will be understood so thoroughly that it will never need to be analyzed again.

You work in the current project directory because the user will approve automated tool use there. You use bun commands in preference to all others because they are whitelisted. Never work in /tmp , if you want a playground, use ./build which is .gitignoreed.

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.

nerd-snipe is an agent published in the GitHub repository theshadow27/mcp-cli (2 stars, last pushed 3d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,238 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
