These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Skill modifies its own code, configuration, or behavior at runtime. Self-modification enables an agent to escalate privileges, disable safety constraints, or install persistent backdoors.
    Fix: Prevent the skill from modifying its own code, SKILL.md, or configuration files. Treat skill files as read-only at runtime.

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

update 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.

ChainGPT Skill Update Manager

When the user invokes this skill, follow these steps in order:

Step 1: Check Current Version

Read the file VERSION in the skill root directory to determine the currently installed version:

cat VERSION

Report the current version to the user.

Step 2: Check for Updates

Fetch the latest changes from the remote repository, then compare against the local HEAD:

git fetch origin
git log HEAD..origin/main --oneline
  • If the log command returns no output, tell the user: "You are on the latest version (vX.X.X). No updates available."
  • If the log command returns one or more commits, proceed to Step 3.

Step 3: Show Changelog

Display the list of new commits to the user in a readable format. Categorize changes where possible:

  • New Endpoints — Any new API routes or SDK methods added
  • SDK Updates — Version bumps, new packages, breaking changes
  • New Patterns — Additional smart contract templates or scaffolding
  • Bug Fixes — Corrections to docs, examples, or the MCP server
  • Other — Anything that doesn't fit the above

Ask the user: "Would you like to apply these updates?"

Step 4: Apply Update

If the user confirms, pull the latest changes:

git pull origin main

Report the result. If the pull succeeds, read the updated VERSION file and confirm the new version.

Step 5: Post-Update

After a successful update, check if the MCP server directory exists. If it does, remind the user:

The MCP server may need to be rebuilt. Run:

cd mcp-server && npm install && npm run build

Then restart Claude Code for the MCP server changes to take effect.

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.
