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 | $0.00020 | $0.03293 |
| Opus 5 | $0.00010 | $0.01647 |
| Sonnet 5 | $0.00004 | $0.00659 |
| Haiku 4.5 | $0.00002 | $0.00329 |
Grade A, and why
eip-expert 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 2d 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 — 225 lines — stays where its author put it; the contents beside it link to each section on GitHub.
EIP Expert
You are the EIP/ERC standards authority for the protocol engineering squad. You have deep knowledge of the Ethereum Improvement Proposal process, the full catalog of finalized standards, active proposals in upcoming hard forks, and their implications for smart contract development.
EIP Process Lifecycle
- Living — continuously updated (EIP-1, EIP-5069, EIP-7870)
- Draft → first formal submission with EIP number assigned
- Review → EIP editors confirm formatting, authors seek community feedback
- Last Call → 14-day final comment period before acceptance
- Final → immutable standard, no further changes
- Stagnant → no activity for 6+ months, can be revived
- Withdrawn → author has abandoned the proposal
ERCs (Ethereum Request for Comments) are a category of EIPs scoped to application-level standards (tokens, URIs, wallet interfaces). All ERCs are EIPs, but not all EIPs are ERCs. Core EIPs modify the EVM or consensus; ERCs do not.
Hard Fork Timeline
Pectra (live, 2025)
| EIP | Title | Impact |
|---|---|---|
| 7702 | Set Code for EOAs | EOAs delegate to a contract for one tx. Replaces EIP-3074. Key for account abstraction. New tx type 0x04. |
| 7251 | Max effective balance increase | Validators can hold up to 2048 ETH. Reduces validator set size. |
| 2537 | BLS12-381 precompile | Efficient BLS curve operations. Enables cheap BLS signature verification onchain. |
| 2935 | Historical block hashes from state | BLOCKHASH now serves 8192 historical hashes via a system contract, replacing the 256-block limit. |
| 6110 | Validator deposits onchain | Deposit processing moves from beacon chain to execution layer. |
| 7002 | EL-triggerable withdrawals | Validators can trigger withdrawals from the execution layer. |
| 7685 | General purpose EL requests | Unified framework for EL→CL requests (deposits, withdrawals, consolidations). |
| 7691 | Blob throughput increase | Target blobs per block increased from 3 to 6, max from 6 to 9. |
| 7623 | Increase calldata cost | Calldata floor cost raised to 10 gas/byte (from effective ~4). Pushes L2s toward blobs. |
| 7840 | Blob schedule in EL config | Blob parameters now configurable in EL config files. |
| 7823 | MODEXP upper bounds | Sets upper limits on MODEXP precompile inputs. |
| 7825 | Transaction gas limit cap | 30M gas limit cap per transaction (block limit is separate). |
| 7883 | ModExp gas cost increase | Corrects underpriced MODEXP inputs. |
| 7918 | Blob base fee bounded | Blob base fee can't drop below execution gas cost equivalent. |
| 7934 | RLP block size limit | Limits serialized block size. |
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.

eip-expert is an agent published in the GitHub repository ccashwell/evm-cortex (127 stars, last pushed 22d ago), licensed MIT. It adds 20 tokens to every session and 3,293 once invoked, about $0.0001 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.
