What it does

Go HTTP Client Resilience is an agent skill from hashgraph-online/awesome-codex-plugins. Design, implement, test, and review resilient Go HTTP client boundaries with context propagation, layered timeouts, transport reuse, request construction, authentication, status classification, bounded bodies, retry safety, backoff, rate limits, pagination, observability, and deterministic fakes. Use when a Go CLI or service calls remote APIs or when HTTP behavior is slow, flaky, unsafe, or hard to test.

Its SKILL.md is about 710 tokens, which your agent loads only when the skill is triggered. The skill folder holds 10 other files, including reference files (for example `agents/openai.yaml`, `guidelines.md` and `references/http-client-resilience/examples.md`). Compatibility notes: Codex, Claude Code, and other Agent Skills-compatible clients.

It sits in Backend & APIs, covering Rate limiting and Observability. The repository describes itself as: A curated list of awesome OpenAI Codex / ChatGPT plugins, skills, and resources. The 1 Codex Marketplace. See live plugins at: https://hol.org/plugins/best-codex-plugins. The licence is MIT.

When your agent uses it

  • Service calls remote APIs
  • HTTP behavior is slow

Example prompts

  • “/go-http-client-resilience”

Requirements

  • Compatibility (from SKILL.md): Codex, Claude Code, and other Agent Skills-compatible clients.

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  1. Define operation semantics, total deadline, idempotency, and response limits.
  2. Reuse a configured client and transport; propagate context into every request.
  3. Construct URLs, headers, authentication, and bodies without secret leakage.
  4. Classify transport, timeout, status, protocol, and decode failures.
  5. Add bounded retries with jitter only for safe transient cases.
  6. Drain or close bodies correctly and bound all reads.
  7. Test with a function-backed transport and focused integration server.

What it can do on your machine

Read from SKILL.md and the folder at commit 9e7b281. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • pkg.go.dev

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Codex, Claude Code, and other Agent Skills-compatible clients.

    From compatibility in the SKILL.md frontmatter.

Context cost

Go HTTP Client Resilience loads about 714 tokens when it runs, and up to ~2.5k if it reads all its reference files. Until then it costs about 108 tokens; SKILL.md has 270 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~108
When it runs · the whole SKILL.md, loaded when a task matches
~714
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.5k

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.

Safety

Auto-check passed

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.

Go HTTP Client Resilience

Treat HTTP as a failure-prone boundary with a finite time and resource budget. Retry only when both the failure and the operation are safe.

Core Workflow

  1. Define operation semantics, total deadline, idempotency, and response limits.
  2. Reuse a configured client and transport; propagate context into every request.
  3. Construct URLs, headers, authentication, and bodies without secret leakage.
  4. Classify transport, timeout, status, protocol, and decode failures.
  5. Add bounded retries with jitter only for safe transient cases.
  6. Drain or close bodies correctly and bound all reads.
  7. Test with a function-backed transport and focused integration server.

Configure deadlines, retries, or paginationreferences/http-client-resilience/rules.md
Review Go patternsreferences/http-client-resilience/examples.md
Understand failure and budget modelsreferences/http-client-resilience/knowledge.md

Guardrails

  • Never use an unbounded body read or an unbounded retry loop.
  • Do not retry unsafe operations without an idempotency mechanism.
  • Do not create a new transport per request.
  • Do not log authorization headers, cookies, tokens, or unreviewed bodies.
  • Close every non-nil response body, including non-2xx responses.

Source Notes

Guidance is transformed and paraphrased from Marian Montagnino, Building Modern CLI Applications in Go (Packt, 2023), especially Chapter 6, and Ricardo Gerardi, Powerful Command-Line Applications in Go (2021).

Streaming, transport-pool, and HTTP test guidance also incorporates transformed material from Inanc Gumus, Go by Example: Programmer's Guide to Idiomatic and Testable Programs (Manning, 2025), Chapter 7.

Body ownership and client-timeout guidance also incorporates transformed material from Teiva Harsanyi, 100 Go Mistakes and How to Avoid Them (Manning, 2022), Chapter 10.

Verify behavior against https://pkg.go.dev/net/http and current API-specific rate-limit, pagination, and idempotency documentation.
