What it does
Quicknode Security Basics is an agent skill from jeremylongshore/tons-of-skills-marketplace. Harden QuickNode endpoints with server-side token handling, separate credentials, least-privilege account roles, and plan-appropriate security filters. Use when reviewing exposure, isolating applications, or responding to a leaked endpoint. Trigger with: "secure QuickNode", "harden a QuickNode endpoint", "rotate a leaked QuickNode token".
Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/official-docs.md`). Compatibility notes: JWT, referrer allowlists, domain masking, and advanced rate controls can be plan-specific
It sits in Backend & APIs, covering Backend development. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.
When your agent uses it
- Reviewing exposure
- Isolating applications
- Responding to a leaked endpoint
- With: secure QuickNode
Example prompts
- “secure QuickNode”
- “harden a QuickNode endpoint”
- “rotate a leaked QuickNode token”
- “/quicknode-security-basics”
Requirements
- Compatibility (from SKILL.md): JWT, referrer allowlists, domain masking, and advanced rate controls can be plan-specific
- Pre-approved tools (allowed-tools): Read, Grep, Write, Edit, Bash(qn:*)
Workflow steps
6 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 80f86df. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadGrepWriteEditBash(qn:*)
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
quicknode.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Compatibility
JWT, referrer allowlists, domain masking, and advanced rate controls can be plan-specific
From compatibility in the SKILL.md frontmatter.
Context cost
Quicknode Security Basics loads about 1k tokens when it runs, and up to ~1.2k if it reads all its reference files. Until then it costs about 92 tokens; SKILL.md has 409 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

QuickNode Endpoint Hardening
Overview
Protect endpoint tokens as credentials, isolate consumers with multiple tokens, and layer only controls that match the client threat model. A browser referrer rule is not a substitute for keeping privileged RPC or account keys on a server.
Prerequisites
- Endpoint inventory with owners, applications, and environments
- Current plan and available endpoint-security controls
- A threat model covering browser, server, CI, and operator access
Instructions
Step 1: Find exposure
Use Read and Grep for quiknode.pro, x-token, x-api-key, JWT configuration, logs, examples, and client bundles. Stop and rotate any live credential committed to Git or shipped to an untrusted client.
Step 2: Separate identities
Create distinct endpoint tokens for applications and environments. Keep Admin API/SDK API keys separate from chain RPC tokens. Apply least-privilege team and account roles.
Step 3: Choose layered controls
Use token authentication for every endpoint. Add JWT for short-lived server authorization when supported, referrer allowlists for browser-origin reduction, and IP or method limits for known traffic patterns. Document plan dependencies.
Step 4: Keep privileged calls server-side
Use Write or Edit to route transaction submission, archive/debug methods, and account-control calls through a trusted backend. Do not embed endpoint or API tokens in public JavaScript.
Step 5: Inspect configuration
Use Bash(qn:*) to read endpoint security state with an approved authenticated operator identity. Compare actual tokens, filters, limits, domains, and team access to the declared policy without printing secret values.
Show full SKILL.md (177 more words)Show less
Step 6: Exercise response
Prove that an unauthorized origin, token, method, or IP is rejected as designed. Revoke one test token and confirm other isolated consumers continue. Record recovery time and escalation owner.
Tool Discipline
Use Read and Grep for exposure discovery, Write/Edit for server-side boundaries and policy, and Bash(qn:*) for read-only security inspection. Credential creation, revocation, and production filter changes require an explicit checkpoint.
Output
- Endpoint threat model and credential map
- Actual-versus-declared security control comparison
- Negative authorization tests
- Rotation and incident-response procedure
Examples
A public dApp calls a backend that holds the endpoint token. Production and staging use separate tokens, and a method limit prevents the public route from invoking debug methods.
Error Handling
| Failure | Response |
|---|---|
| Token exposed | Revoke, replace, sanitize history and logs, then investigate use |
| Referrer rule blocks valid traffic | Roll back the specific rule; do not expose the token |
-32611 rejection | Compare method and filter policy before retrying |
| Security feature unavailable | Record the plan gap and enforce the boundary in the application |
