flexport-common-errorsClassify Flexport REST, OAuth, webhook, and MCP failures into safe operator actions.
Flexport Common Errors is an agent skill from jeremylongshore/tons-of-skills-marketplace. Classify Flexport REST, OAuth, webhook, and MCP failures into safe operator actions. Use when triaging status/code/message errors, permission failures, validation problems, or ambiguous mutations. Trigger with: "debug Flexport error", "Flexport 422", "Flexport permission denied".
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 a redacted response receipt with surface, operation, HTTP or JSON-RPC status, and correlation metadata.
It sits in Backend & APIs, covering Webhooks and OAuth and OpenID Connect. 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 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:
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:
apidocs.flexport.comdevelopers.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 a redacted response receipt with surface, operation, HTTP or JSON-RPC status, and correlation metadata.
From compatibility in the SKILL.md frontmatter.
Flexport Common Errors 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 76 tokens; SKILL.md has 422 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-common-errors/SKILL.md (or your agent's skills folder). This skill also uses 1 other file; get the full folder from GitHub.Do not convert every failure into a retry. First identify the surface and operation class, then distinguish authentication, authorization, validation, provider availability, and ambiguous mutation outcomes.
Label OAuth token, REST v3, MCP JSON-RPC, or webhook delivery; each has different failure semantics.
Capture timestamp, credential alias, version header, operation digest, status/code/message, and provider correlation metadata without payloads or secrets.
Separate 401 authentication, 403 permission/scope, 404 resource or route, 400/422 request validation, throttling evidence, and 5xx/transport uncertainty.
Retry only transient, idempotent work with bounded backoff. Never retry a create or booking until its prior outcome is reconciled.
Route credential issues to credential owners, schema issues to integration owners, business validation to data owners, and provider incidents to support.
Record the corrected contract or recovered result and add a regression fixture when the defect was local.
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-platformA document upload returns 422 with a provider message. The operator preserves the code/message, fixes the source document metadata, and submits a new approved operation rather than repeatedly sending the unchanged payload.
| Failure | Response |
|---|---|
| 401 persists after one cached-token refresh | Stop and inspect credential revocation, audience, and secret source. |
| 403 on one endpoint | Verify OAuth endpoint resources or MCP role permission; do not broaden silently. |
404 on /tools/... | Use the real MCP JSON-RPC endpoint rather than the synthetic docs path. |
| Timeout after mutation | Reconcile using known references before any retry. |

Classify Flexport REST, OAuth, webhook, and MCP failures into safe operator actions. Flexport Common Errors is an agent skill from jeremylongshore/tons-of-skills-marketplace. Classify Flexport REST, OAuth, webhook, and MCP failures into safe operator actions.
Flexport Common Errors fits situations like: triaging status/code/message errors; permission failures; validation problems; ambiguous mutations.
Run `npx skills add jeremylongshore/tons-of-skills-marketplace --skill flexport-common-errors -a claude-code`. Or copy the skill folder (skills/.curated/flexport-common-errors in jeremylongshore/tons-of-skills-marketplace) into .claude/skills/flexport-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 flexport-common-errors -a codex`. Or copy the skill folder (skills/.curated/flexport-common-errors in jeremylongshore/tons-of-skills-marketplace) into .agents/skills/flexport-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 flexport-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/flexport-common-errors, .gemini/skills/flexport-common-errors, .github/skills/flexport-common-errors and .opencode/skills/flexport-common-errors in your project.
SKILL.md names no scripts, command-line tools or credentials: Flexport Common Errors is instructions for the agent only. Its frontmatter pre-approves these tools: Read, Grep, Write, Edit. Compatibility (from SKILL.md): Requires a redacted response receipt with surface, operation, HTTP or JSON-RPC status, and correlation metadata..
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: apidocs.flexport.com and developers.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 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 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 213 tokens, read only when the agent opens those files.
