What it does

HTTP Evidence is an agent skill from deonmenezes/mantishack. Turn a captured HTTP request/response into a bounded, redacted evidence pack with a stable request-ref using the mantishttpaudit MCP server, instead of pasting raw traffic into a finding

Its SKILL.md is about 460 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 Agent Workflows. It works with Model Context Protocol. The licence is Apache-2.0.

When your agent uses it

  • Agent Workflows work in your project

Example prompts

  • “/http-evidence”

What it can do on your machine

Read from SKILL.md and the folder at commit c3a2e68. 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

    No URLs in SKILL.md.

    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 Evidence loads about 455 tokens when it runs. Until then it costs about 51 tokens; SKILL.md has 228 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~51
When it runs · the whole SKILL.md, loaded when a task matches
~455

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.

description
Turn a captured HTTP request/response into a bounded, redacted evidence pack with a stable request-ref using the mantis_http_audit MCP server, instead of pasting raw traffic into a finding

Use http_audit (mantis_http_audit MCP server) whenever you have a captured HTTP exchange that proves a web finding, before attaching it as evidence. It converts raw request/response text into a bounded, redacted evidence pack and a stable request_ref/response_ref hash.

Why go through it instead of pasting the raw exchange into the finding:

  • It strips secret-bearing headers (Authorization, Cookie, Set-Cookie, X-Api-Key, CSRF tokens, ...) and inline secrets (AWS keys, GitHub/Slack tokens, JWTs, private keys, user:pass@ in URLs). Raw secrets must never land in a finding, artifact, report, or prompt (PRD section 9/11).
  • It bounds the body: full bodies are hashed and previewed (first 512 bytes), never stored whole.
  • The request_ref is a stable hash of the exchange, so the same request always maps to the same id -- use it to cross-reference and dedup evidence across findings.

Workflow: capture the request (and response) text -> call http_audit({ request, response }) -> attach the returned request_ref/response_ref and the redacted pack to the finding via mantis_findings finding_update evidence. The tool makes NO network call itself; you pass in traffic you already captured under authorized, scoped testing.

Do not defeat the redaction by separately pasting the raw header/body you just redacted into the finding or report. If you need to prove a specific secret was exposed, reference it by its redaction label and location, and follow the secrets-scan skill's remediation guidance (rotate/revoke, then remove from source and history).

Can I use HTTP Evidence in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add deonmenezes/mantishack --skill http-evidence -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/http-evidence, .gemini/skills/http-evidence, .github/skills/http-evidence and .opencode/skills/http-evidence in your project.

What does HTTP Evidence need to run?

SKILL.md names no scripts, command-line tools or credentials: HTTP Evidence is instructions for the agent only.

Does HTTP Evidence access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is HTTP Evidence safe to install?

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.
