What it does

Harness Help is an agent skill from PromptPartner/agentsmith. Orient a non-coder to this project's Agentsmith harness — fires on "what is this harness?", "what are my rules?", "which profile am I on?", "what do I type next?". Part of the Agentsmith harness; reads the canonical instructions and selected agent's safety configuration, then reports the profile, rules, safety mode, and next step in plain language.

Its SKILL.md is about 570 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts. Compatibility notes: Requires an Agent Skills-compatible coding agent with filesystem access.

It sits in Writing & Content, covering Plain language and style rules. The repository describes itself as: Universal, model-agnostic operating harness for AI agents (Claude, Codex, Gemini, …) — a lean core + work-type profiles assembled by one setup script. The licence is MIT.

When your agent uses it

  • Tasks that involve Plain language and style rules

Example prompts

  • “s Agentsmith harness — fires on”
  • “what are my rules?”
  • “which profile am I on?”
  • “/harness-help”

Requirements

  • Compatibility (from SKILL.md): Requires an Agent Skills-compatible coding agent with filesystem access.

Workflow steps

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

  1. Active profile(s) — the work-type this project is tuned for (from the profile section).
  2. Your rules, in 3–5 bullets — the load-bearing ones (verify before done, protected main,
  3. Safety mode — when an agent is declared, read its managed native configuration and explain
  4. What to type next — take one small task end to end. Say “verify” or “handoff”; mention an

What it can do on your machine

Read from SKILL.md and the folder at commit b293c3a. 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.

  • Compatibility

    Requires an Agent Skills-compatible coding agent with filesystem access.

    From compatibility in the SKILL.md frontmatter.

Context cost

Harness Help loads about 568 tokens when it runs. Until then it costs about 91 tokens; SKILL.md has 275 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~91
When it runs · the whole SKILL.md, loaded when a task matches
~568

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.

Harness help — get oriented

Explain, in plain language with no jargon, what this harness does for the operator and what to do next. This is the non-coder's front door.

When this fires

"what is this harness / what does it do?" / "what are my rules?" / "which profile am I on?" / "what do I type next?" / a general "help me get started here".

Identify the target

Use the agent named by the operator or the explicit AGENTSMITH_AGENT value. Never infer the active agent from this skill's install path: portable canonical content may be copied into a required client adapter such as .claude/skills. Without a declared agent, explain the common rules and label agent-specific safety configuration as unknown.

What to do (no script needed)

Read the canonical managed block in AGENTS.md and report:

  1. Active profile(s) — the work-type this project is tuned for (from the profile section).
  2. Your rules, in 3–5 bullets — the load-bearing ones (verify before done, protected main, look before you delete, be honest about what failed). Summarize; don't dump the file.
  3. Safety mode — when an agent is declared, read its managed native configuration and explain the effective approval and sandbox settings. Otherwise say that client-specific safety was not identified.
  4. What to type next — take one small task end to end. Say “verify” or “handoff”; mention an invocation prefix only when the declared client documents one.

Point to docs/01-harness-philosophy.md and docs/07-how-to-pick-a-profile.md for the why and the profile choices. If FIRST-STEPS.md exists, point at it too.

Report

A short, friendly orientation: the selected agent when known, profile, a few rules, safety mode, and the one thing to do next. No file dumps, no jargon.
