flexport-observabilityInstrument Flexport REST, MCP, OAuth, and webhook outcomes without logging logistics payloads or credentials.
Flexport Observability is an agent skill from jeremylongshore/tons-of-skills-marketplace. Instrument Flexport REST, MCP, OAuth, and webhook outcomes without logging logistics payloads or credentials. Use when defining metrics, traces, dashboards, or alerts. Trigger with: "monitor Flexport integration", "Flexport metrics", "trace Flexport webhooks".
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 an approved telemetry platform, redaction policy, and business service objectives.
It sits in Backend & APIs, covering Webhooks, Observability 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 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:
apidocs.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 an approved telemetry platform, redaction policy, and business service objectives.
From compatibility in the SKILL.md frontmatter.
Flexport Observability 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 71 tokens; SKILL.md has 402 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 1 other file; get the full folder from GitHub.Observe operations and reconciliation, not shipment contents. Build low-cardinality telemetry around surface, operation class, outcome, version, and queue health while keeping identifiers and payloads out.
Use environment, surface, operation class, status family, error class, version selection, and release. Exclude URLs with IDs, names, emails, routes, tags, documents, tokens, and raw messages.
Track cache hit, refresh success, token-request count, and credential alias as a controlled internal dimension; never log tokens or secret fragments.
Record latency, attempts, pages, queue age, reconciliation lag, and ambiguous outcomes by operation class.
Distinguish received, signature-valid, durably queued, deduplicated, processed, and reconciled counts.
Derive thresholds from approved freshness, queue, and error objectives—not arbitrary fixed seconds or undocumented rate headers.
Sample schemas and label cardinality for sensitive leakage and regressions before expanding collection.
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 dashboard shows surface=mcp, operation=shipment-read, outcome, latency, and reconciliation lag. It never labels a series with FLEX-ID, route, company, email, or tool arguments.
| Failure | Response |
|---|---|
| Identifier appears in labels | Drop or hash only under approved policy, then control cardinality. |
| Raw provider message contains data | Map to a safe error class and protect restricted details separately. |
| Alert has no business objective | Disable it until an owner defines the decision it drives. |
| Webhook counts diverge | Bound the window and run authenticated reconciliation. |

Instrument Flexport REST, MCP, OAuth, and webhook outcomes without logging logistics payloads or credentials. Flexport Observability is an agent skill from jeremylongshore/tons-of-skills-marketplace. Instrument Flexport REST, MCP, OAuth, and webhook outcomes without logging logistics payloads or credentials.
Flexport Observability fits situations like: defining metrics; with: monitor Flexport integration; flexport metrics; trace Flexport webhooks.
Run `npx skills add jeremylongshore/tons-of-skills-marketplace --skill flexport-observability -a claude-code`. Or copy the skill folder (skills/.curated/flexport-observability in jeremylongshore/tons-of-skills-marketplace) into .claude/skills/flexport-observability in your project. Claude Code loads it when a task matches its description.
Run `npx skills add jeremylongshore/tons-of-skills-marketplace --skill flexport-observability -a codex`. Or copy the skill folder (skills/.curated/flexport-observability in jeremylongshore/tons-of-skills-marketplace) into .agents/skills/flexport-observability 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-observability -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-observability, .gemini/skills/flexport-observability, .github/skills/flexport-observability and .opencode/skills/flexport-observability in your project.
SKILL.md names no scripts, command-line tools or credentials: Flexport Observability is instructions for the agent only. Its frontmatter pre-approves these tools: Read, Grep, Write, Edit. Compatibility (from SKILL.md): Requires an approved telemetry platform, redaction policy, and business service objectives..
SKILL.md names 3 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. 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 Observability 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 4.2k 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 215 tokens, read only when the agent opens those files.
