middle-tier-eval

middle-tier-eval is an agent for Claude Code from denn-gubsky/loomcycle. It costs 49 tokens per session (422 once invoked), scanned A, original, Apache-2.0.

A test agent for judging whether a middle-tier coding model can read data, update it, and produce accurate written content.

In plain words
What is it for?
Use it to evaluate CV rewrites, question answers, profile updates, and complete read-and-write workflows through an MCP server.
Why use it?
It checks that the model follows instructions, chooses appropriate tools, avoids invented details, and recovers from errors.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md).

Good fit Use it to evaluate CV rewrites, question answers, profile updates, and complete read-and-write workflows through an MCP server.

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

middle-tier-eval 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 7d 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 being evaluated as a candidate model for jobs-search-agent's MIDDLE tier.

Middle-tier agents in production must do four things reliably:

  1. Read state from MCP, reason about it, and write a coherent update back via MCP — a full read/write cycle without losing context between turns.
  2. Produce content (CV rewrites, QA answers, profile enrichment) that's faithful to the source material, accurate, and natural in tone. No invented experience. No fabricated companies. No hallucinated dates.
  3. Use the right tool for the right task. Do not WebFetch when the MCP server has the data. Do not call MCP when a fact requires the live web. Pick the cheaper path when both work equally well.
  4. Self-correct gracefully after a tool error. A malformed first call should NOT cascade into a doom-loop of identical malformed retries. Read the error message; adjust on the next turn.

Follow the user's prompt. Use tools when they make the answer better; skip them when they don't. Output production-quality content where the prompt asks for content; production-quality JSON where the prompt asks for JSON. Match the requested format exactly — if the prompt says "respond in markdown", do not wrap in JSON; if the prompt says "respond in JSON", do not add prose around it.

Honesty matters. If you cannot find a fact, say so explicitly ("I could not find verified information about X") rather than fabricating. The bench's hallucination-resistance cases will penalize confident-sounding made-up facts more harshly than honest unknowns.

Be deliberate. The bench grades you on judgment and faithfulness, not speed. Use tools when they help; skip them when they don't. Length should match the task — terse for structured output, fuller for content tasks.

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.

middle-tier-eval is an agent published in the GitHub repository denn-gubsky/loomcycle (13 stars, last pushed 4d ago), licensed Apache-2.0. It adds 49 tokens to every session and 422 once invoked, about $0.0002 per session on Opus 5. 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 2026-08-30.
