What it does

HTTP Toolkit Intercept is an agent skill from Factory-AI/factory-plugins. Intercept and debug HTTP traffic from any CLI, service, or script using HTTP Toolkit. Use when you need to inspect LLM API calls, backend requests, auth flows, or debug network-level issues across any language or runtime.

Its SKILL.md is about 2.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in AI & LLM Engineering, covering Authentication and LLM API integration. The repository describes itself as: Official Factory plugins marketplace.

When your agent uses it

  • You need to inspect LLM API calls
  • Backend requests
  • Debug network-level issues across any language

Example prompts

  • “/http-toolkit-intercept”

Requirements

  • Python 3
  • Node.js
  • Docker

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Launch your program with the proxy env vars set
  2. Capture the inbound session log
  3. Export outbound HTTP from HTTP Toolkit
  4. Cross-reference the two streams

What it can do on your machine

Read from SKILL.md and the folder at commit d362dc1. 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

    Shell commands in SKILL.md call:

    • curl
    • jq

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

  • Network

    No URLs in SKILL.md. Its commands use curl, which can reach the network depending on how they are called.

    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.

Context cost

HTTP Toolkit Intercept loads about 2.5k tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 1,120 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~61
When it runs · the whole SKILL.md, loaded when a task matches
~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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 1,120 words (~2,461 tokens).

“Use this skill when you need authoritative evidence of what your program sent to a remote API and what it received back while verifying a code change. Works across any runtime — Node.js, Bun, Deno, Python, Go, Ruby, Java/JVM, .NET…”
