Download and extract https://github.com/hanzohanzhe/Grandet/releases/download/skill-v0.3.0-build.20261018/grandet-api-price-finder-0.3.0.zip. In mainland China, or after a GitHub download takes 30 seconds or fails once, switch to https://api.skillhub.cn/api/v1/download?slug=grandet-api-price-finder&version=0.3.0-build.20261018.0 without repeatedly retrying GitHub. Extract the SkillHub archive into a new grandet-api-price-finder folder; its files are at the archive root. A SkillHub 404 means the build is still under review; use GitHub instead. Retain the complete skill, including SKILL.md, references/, and agents/.

Before relying on either downloaded archive, independently verify it against the published content manifest and asset SHA-256. Also check file hashes against package-manifest.json when present.

Before running the receipt-aware installer, explain that installation statistics contain random IDs, operation, version, content hash, source/host/scope categories, verification, and time, retained for 24 months. No path, username, account, chat, or key is sent. The documented opt-outs are --no-telemetry or GRANDET_INSTALL_TELEMETRY=0; offline installation also works.

For the GitHub installation ZIP route, run this command in a terminal from the extracted ZIP root. Replace <installer-id> with codex, claude-code, cursor, or hermes for the current app only. The respective skill directories are ~/.agents/skills/, ~/.claude/skills/, ~/.cursor/skills/, and $HERMES_HOME/skills/ when HERMES_HOME is set, otherwise ~/.hermes/skills/. For the SkillHub fallback, skip this ZIP-specific command and use the manual-copy step below.

node scripts/install-price-finder.mjs --app <installer-id> --receipt-source release_zip

For the SkillHub fallback, copy the entire extracted grandet-api-price-finder folder into the current app's skill directory listed above. Keep an identical existing copy; move a differing copy outside every skills folder as a backup before replacing it. Keep exactly one active copy, do not follow symlinks outside the skill, and leave other skills, model settings, and provider keys untouched. Manual copying retains a receipt coverage gap.

Read back the installed SKILL.md, confirm references/ and agents/ are complete, and check that Installation build names grandet-skill-0.3.0-build.20261018. Check anonymous access to https://grandet.ai/public-data/price-finder.json through Grandet MCP or a plain HTTP GET. Restart the app or open a clean new conversation without attaching files to check persistence; report any check that could not be performed as untested.

Extract the SkillHub archive into a new grandet-api-price-finder folder; that folder is the complete skill. A SkillHub 404 means the build is still under review; use GitHub instead.

Before relying on either downloaded archive, independently verify it against the published content manifest and asset SHA-256. Also check file hashes against package-manifest.json when present. Keep the complete skill folder, including SKILL.md, references/, and agents/; SKILL.md alone is insufficient.

Check for an existing grandet-api-price-finder installation. Keep an identical copy; move a differing copy outside every skills folder as a backup. Copy the complete skills/grandet-api-price-finder folder from the GitHub ZIP, or the complete grandet-api-price-finder folder extracted from SkillHub, into ~/.agents/skills/ for Codex, ~/.claude/skills/ for Claude Code, or ~/.cursor/skills/ for Cursor. Keep exactly one active copy, avoid following symlinks outside the folder, and leave other skills and settings untouched. On Windows, replace <your name> in the home-directory notation with your Windows username.

Read back the installed SKILL.md, confirm references/ and agents/ are complete, and check that Installation build names grandet-skill-0.3.0-build.20261018. Check anonymous access to https://grandet.ai/public-data/price-finder.json through Grandet MCP or plain HTTP GET. Restart the app or open a new conversation; confirm the skill persists without attaching its files again. Report unavailable checks as untested.

In mainland China, or after GitHub takes 30 seconds or fails once, switch to https://api.skillhub.cn/api/v1/download?slug=grandet-api-price-finder&version=0.3.0-build.20261018.0 without repeatedly retrying GitHub. Extract the SkillHub archive into a new grandet-api-price-finder folder. A SkillHub 404 means the build is still under review; use GitHub instead.

Before relying on either downloaded archive, independently verify it against the published content manifest and asset SHA-256. Also check package-manifest.json file hashes when present. For GitHub, upload the native .skill archive; rename a copy to .zip if the app accepts only ZIP. For SkillHub, zip the extracted grandet-api-price-finder folder and upload that. Do not upload the larger installation ZIP.

In ChatGPT, open https://chatgpt.com/skills → Add skill → Upload from computer. In Claude on the web, use Customize → Skills → + → Create skill → Upload a skill. Upload and enable the skill. Update an existing saved Grandet skill in place rather than creating a second copy; a chat attachment alone does not install it.

Where saved-file readback is available, confirm the installed SKILL.md build is grandet-skill-0.3.0-build.20261018 and references/ and agents/ are complete. Match any separate description field to the current SKILL.md frontmatter. Check anonymous access to https://grandet.ai/public-data/price-finder.json through Grandet MCP or plain HTTP GET. Open a clean new conversation without attaching files to check persistence. Uploading does not automatically execute the verifier; report unavailable saved-file readback or host verification as unverified.
