juicebox-upgrade-migrationPlan Juicebox SDK upgrades. An agent skill from jeremylongshore/tons-of-skills-marketplace.
Juicebox Upgrade Migration is an agent skill from jeremylongshore/tons-of-skills-marketplace. Plan Juicebox SDK upgrades. Trigger: "upgrade juicebox", "juicebox migration".
Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/implementation-guide.md` and `references/implementation.md`). Compatibility notes: Designed for Claude Code
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 cfae287. 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:
ReadWriteEditBash(npm:*)From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript).
From the folder's file list and the shell code blocks in SKILL.md.
Hosts in commands or code, which the agent is likely to contact:
api.juicebox.workFrom URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Designed for Claude Code
From compatibility in the SKILL.md frontmatter.
Juicebox Upgrade Migration loads about 1.6k tokens when it runs, and up to ~3k if it reads all its reference files. Until then it costs about 26 tokens; SKILL.md has 398 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.

This skill also uses 2 other files; get the full folder from GitHub.Juicebox is an AI-powered people search and analysis platform used for recruiting and market research. The API provides endpoints for dataset management, people searches, and AI-generated analyses. Tracking API versions is essential because Juicebox evolves its search query syntax, dataset schema, and analysis output format — upgrading without testing can break saved search filters, corrupt dataset imports, and change the structure of AI-generated candidate profiles that downstream systems consume.

}| Migration Issue | Symptom | Fix |
|---|---|---|
| Search filter syntax changed | 400 Bad Request with invalid filter operator | Update filter syntax to new query DSL format |
| Dataset schema mismatch | Import succeeds but columns mapped incorrectly | Re-map dataset columns using /datasets/schema endpoint |
| Profile field restructured | Code crashes accessing result.name (now result.profile.full_name) | Update all property access paths to new nested structure |
| Analysis format changed | AI analysis output missing expected sections | Update parser for new structured analysis response |
| Rate limit reduced | 429 Too Many Requests on previously working batch sizes | Reduce batch size and implement request queuing |

SKILL.md names no scripts, command-line tools or credentials: Juicebox Upgrade Migration is instructions for the agent only. Its frontmatter pre-approves these tools: Read, Write, Edit, Bash(npm:*). Compatibility (from SKILL.md): Designed for Claude Code.
SKILL.md names 1 domain. In commands or code: api.juicebox.work; the agent is likely to contact it when it follows the instructions. 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.
Juicebox Upgrade Migration is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.6k tokens (SKILL.md is roughly 6.5k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 1.4k tokens, read only when the agent opens those files.
