flexport-multi-env-setupSeparate Flexport development, test, staging, and production configuration without inventing provider hostnames or key prefixes.
Flexport Multi Env Setup is an agent skill from jeremylongshore/tons-of-skills-marketplace. Separate Flexport development, test, staging, and production configuration without inventing provider hostnames or key prefixes. Use when creating environments, test credentials, receivers, or promotion rules. Trigger with: "Flexport environments", "Flexport staging setup", "separate Flexport credentials".
Its SKILL.md is about 1.1k 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: Requires environment owners, separate secret stores, and Flexport/account-executive coordination for any test credential.
It works with Model Context Protocol. 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.
6 steps, taken from the step headings 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:
ReadGrepWriteEditFrom allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md (its code samples are yaml).
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.flexport.commcp.flexport.comAlso links to:
developers.flexport.comapidocs.flexport.comFrom 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.
Requires environment owners, separate secret stores, and Flexport/account-executive coordination for any test credential.
From compatibility in the SKILL.md frontmatter.
Flexport Multi Env Setup loads about 1.1k tokens when it runs, and up to ~1.3k if it reads all its reference files. Until then it costs about 83 tokens; SKILL.md has 401 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/flexport-multi-env-setup/SKILL.md (or your agent's skills folder). This skill also uses 1 other file; get the full folder from GitHub.Flexport documents the same API base rather than arbitrary environment URLs. Isolation comes from accounts/credentials, receiver URLs, data policy, and mutation gates; a test credential may require coordination with the account executive.
For every environment record account identity, credential type, endpoint resources, version behavior, receiver, data class, and permitted operations.
Never share client IDs, client secrets, API keys, cached tokens, or MCP sessions across environments.
Use documented Flexport API/MCP hosts. Do not invent staging subdomains or infer an environment from a credential prefix.
Request any Flexport test credential through the documented account-executive route and keep local/default tests fixture-only.
Promote immutable artifacts while supplying environment-specific secret references and config. Production mutations remain disabled until canary approval.
Test that each environment rejects another's credential alias, callback destination, queue, and data-store identity.
REST calls authenticate with a cached OAuth 2.0 client-credentials Bearer token using audience https://api.flexport.com, or an explicitly accepted broad API key. Use distinct credentials per workload and never log credentials or tokens. MCP calls use the authenticated connection to https://mcp.flexport.com/mcp and remain subject to each tool's documented account permissions.
Use Read and Grep for discovery and evidence. Use Write or Edit only for the approved artifact, code, configuration, test, or receipt described by this workflow; do not make an unapproved Flexport-side change.
Return a machine-reviewable receipt in this shape; adapt the operation values, but never place credentials or provider payloads in it:
surface: rest-v3
operation: shipment-read
decision: approved
outcome: verified
evidence:
release_sha: recorded-out-of-band
provider_reference: redacted
rollback_owner: logistics-platformStaging and production run the same artifact against documented hosts, but use different credential records, callback URLs, queues, stores, and mutation flags. Default developer tests use no live Flexport credential.
| Failure | Response |
|---|---|
| Credential reused across environments | Rotate or separate it before promotion. |
| Undocumented environment host configured | Remove it and verify the official account/credential model. |
| Production data enters test | Contain and delete under policy, then repair routing controls. |
| Test credential unavailable | Use sanitized fixtures; do not borrow production access. |

Run `npx skills add jeremylongshore/tons-of-skills-marketplace --skill flexport-multi-env-setup -a claude-code`. Or copy the skill folder (skills/.curated/flexport-multi-env-setup in jeremylongshore/tons-of-skills-marketplace) into .claude/skills/flexport-multi-env-setup in your project. Claude Code loads it when a task matches its description.

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 flexport-multi-env-setup -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/flexport-multi-env-setup, .gemini/skills/flexport-multi-env-setup, .github/skills/flexport-multi-env-setup and .opencode/skills/flexport-multi-env-setup in your project.
SKILL.md names no scripts, command-line tools or credentials: Flexport Multi Env Setup is instructions for the agent only. Its frontmatter pre-approves these tools: Read, Grep, Write, Edit. Compatibility (from SKILL.md): Requires environment owners, separate secret stores, and Flexport/account-executive coordination for any test credential..
SKILL.md names 4 domains. In commands or code: api.flexport.com and mcp.flexport.com; the agent is likely to contact these when it follows the instructions. As links in the text: developers.flexport.com and apidocs.flexport.com. 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.
Flexport Multi Env Setup is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.1k tokens (SKILL.md is roughly 4.3k 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 224 tokens, read only when the agent opens those files.
