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 | $0.00090 | $0.00653 |
| Opus 5 | $0.00045 | $0.00327 |
| Sonnet 5 | $0.00018 | $0.00131 |
| Haiku 4.5 | $0.00009 | $0.00065 |
Grade A, and why
upgrade-blockscout-api 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 8d 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 — 42 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Upgrade Blockscout API
Refresh the API reference files bundled inside one of this repo's end-user skills.
The two skills published from this repo each carry their own snapshot of the Blockscout API surface, but they're built from completely different upstream artefacts and on independent release cadences. Coupling their refreshes would force spurious diffs on whichever target's upstream hasn't moved, so this skill takes a target argument and runs only that target's pipeline.
Invocation
/upgrade-blockscout-api <target>
<target> must be one of:
| Target | Refreshes | Procedure |
|---|---|---|
blockscout-analysis |
blockscout-analysis/references/blockscout-api/*.md and the master index, from latest Blockscout backend + Stats releases. |
references/blockscout-analysis.md |
web3-dev |
web3-dev/references/pro-api.json and web3-dev/references/pro-api-index.md, from a build-time clone of the pro-api repo. |
references/web3-dev.md |
Routing rule
- Read the
<target>argument from the user's invocation. If it is missing or not in the table above, stop and ask which target to upgrade — listing the valid values. Do not guess and do not run both. - Read the matching reference file under
references/and follow it end-to-end. The reference is the canonical, authoritative procedure for that target. - Do not mix instructions across targets. The two procedures share no structural steps; lifting a step from one into the other will silently corrupt the bundled output.
Working directory
Both procedures assume the working directory is the repository root (the parent of blockscout-analysis/ and web3-dev/). Confirm this before running any script — the indexers and patch tools resolve paths relative to the repo root and will write to the wrong place otherwise.
Adding a new target
When a third skill in this repo starts bundling Blockscout API references, add it as a new row in the routing table above and drop a references/<new-target>.md file alongside the existing two. Keep this SKILL.md as routing only — every target's procedure lives in its own reference file so the agent loads only what the current run needs.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

upgrade-blockscout-api is a skill published in the GitHub repository blockscout/agent-skills (35 stars, last pushed 2mo ago), licensed MIT. It adds 90 tokens to every session and 653 once invoked, about $0.0005 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.
