hex-common-errorsDiagnose and fix Hex common errors and exceptions. An agent skill from jeremylongshore/tons-of-skills-marketplace.
Hex Common Errors is an agent skill from jeremylongshore/tons-of-skills-marketplace. Diagnose and fix Hex common errors and exceptions. Use when encountering Hex errors, debugging failed requests, or troubleshooting integration issues. Trigger with phrases like "hex error", "fix hex", "hex not working", "debug hex".
Its SKILL.md is about 840 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts. Compatibility notes: Designed for Claude Code
It sits in Development, covering Debugging. It works with SQL. 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.
4 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 80f86df. It shows what the files ask for, not the result of running them.
Pre-approves these tools, so the agent can use them without asking each time:
ReadGrepBash(curl:*)From allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:
curlpython3From the folder's file list and the shell code blocks in SKILL.md.
Links to these hosts (documentation or services it may open):
learn.hex.techFrom URLs in SKILL.md, links to its own repository left out.
Names these keys or tokens, usually read from environment variables:
HEX_API_TOKENFrom names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Designed for Claude Code
From compatibility in the SKILL.md frontmatter.
Hex Common Errors loads about 837 tokens when it runs. Until then it costs about 63 tokens; SKILL.md has 333 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.
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.

.claude/skills/hex-common-errors/SKILL.md (or your agent's skills folder).Cause: Token invalid, expired, or missing. Fix: Regenerate token in Hex workspace settings.
Cause: Token has "Read projects" scope but RunProject requires "Run projects". Fix: Create new token with "Run projects" scope.
Cause: Project ID wrong or project not published. Fix: Verify project ID. Only published projects can be run via API.
Cause: RunProject is limited to 20 requests/min, 60/hr.
Fix: Queue runs with delays. See hex-rate-limits.
Cause: SQL query, Python code, or connection error in the project. Fix: Open the project in Hex UI and check the error in the run history.
Cause: Run exceeded timeout or was manually cancelled. Fix: Optimize slow queries. Increase timeout in API trigger.

Return error class, correlation ID, project scope, probe outcome, remediation attempted, and next owner. Do not include SQL, output, credentials, or identities.
Treat unknown destination, failed redaction, access expansion, or repeated non-idempotent run as a stop condition. Cancel or restore the prior revision rather than retrying with broader scope.

Hex Common Errors fits situations like: encountering Hex errors; debugging failed requests; troubleshooting integration issues; with phrases like hex error.
Run `npx skills add jeremylongshore/tons-of-skills-marketplace --skill hex-common-errors -a claude-code`. Or copy the skill folder (skills/.curated/hex-common-errors in jeremylongshore/tons-of-skills-marketplace) into .claude/skills/hex-common-errors in your project. Claude Code loads it when a task matches its description.
Run `npx skills add jeremylongshore/tons-of-skills-marketplace --skill hex-common-errors -a codex`. Or copy the skill folder (skills/.curated/hex-common-errors in jeremylongshore/tons-of-skills-marketplace) into .agents/skills/hex-common-errors in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add jeremylongshore/tons-of-skills-marketplace --skill hex-common-errors -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/hex-common-errors, .gemini/skills/hex-common-errors, .github/skills/hex-common-errors and .opencode/skills/hex-common-errors in your project.
Going by SKILL.md and its folder, Hex Common Errors needs the command-line tools its instructions call (curl and python3) and credentials named HEX_API_TOKEN. Our summary lists: Python 3; A credential in HEX_API_TOKEN. Its frontmatter pre-approves these tools: Read, Grep, Bash(curl:*). Compatibility (from SKILL.md): Designed for Claude Code.
SKILL.md names 1 domain. As links in the text: learn.hex.tech. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Hex Common Errors is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 837 tokens (SKILL.md is roughly 3.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
