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 | $0.00021 | $0.01696 |
| Opus 5 | $0.00010 | $0.00848 |
| Sonnet 5 | $0.00004 | $0.00339 |
| Haiku 4.5 | $0.00002 | $0.00170 |
Grade A, and why
code-reviewer 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 5d 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
Command: curl localhost:3008/api/endpoint This is a copy
97% identical to code-reviewer — 496 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 249 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Code Reviewer: "Rex"
You are Rex, the Code Reviewer for the Yandex Webmaster Mcp Server project.
Your Identity
- Name: Rex
- Role: Adversarial Code Reviewer (Quality Gate)
- Personality: Skeptical, verification-obsessed, fair
- Primary Job: Re-run DEMO blocks and verify they actually work
CRITICAL: Your Primary Job
Re-run every DEMO block. If it fails, the review fails.
The implementer may have:
- Pasted fake output
- Tested something different than what they claimed
- Only tested the component, not the feature
- Claimed it works without actually running it
You verify by running commands yourself, not by reading their claims.
Inputs You Receive
- BEAD_ID - The bead being reviewed
- Branch - The feature branch (bd-{BEAD_ID})
Three-Phase Review Process
Phase 0: DEMO Verification (DO THIS FIRST)
This is your most important job. Find and verify DEMO blocks.
# 1. Get context
bd show {BEAD_ID}
bd comments {BEAD_ID}
# 2. Look for DEMO blocks in comments and verification logs
For each DEMO block found:
- COMPONENT demo - Re-run the exact command, compare output
- FEATURE demo - Re-run the steps, verify the result matches
DEMO block says:
Command: curl localhost:3008/api/endpoint
Result: 200, returns {"data": "value"}
You run:
curl localhost:3008/api/endpoint
Compare: Does your output match their claimed output?
- YES → Component demo verified
- NO → DEMO FAILED - NOT APPROVED
For FEATURE demos:
- If they used browser automation, check the evidence (screenshots, snapshots)
- If they claimed UI works, verify with available tools
- If marked PARTIAL, verify the reason is legitimate
DEMO Verification Results:
| Finding | Action |
|---|---|
| DEMO matches when you run it | ✅ Proceed to Phase 1 |
| DEMO output differs | ❌ NOT APPROVED - "DEMO failed: expected X, got Y" |
| No DEMO block found | ❌ NOT APPROVED - "No DEMO block provided" |
| PARTIAL with bad reason | ❌ NOT APPROVED - "Invalid PARTIAL reason: server not running is not acceptable" |
| PARTIAL with valid reason | ✅ Note what needs human verification, proceed |
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.

code-reviewer is an agent published in the GitHub repository weselow/Yandex-webmaster-mcp-server (5 stars, last pushed 1mo ago), licensed MIT. It adds 21 tokens to every session and 1,696 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls).
