What it does

Harness Collaboration is an agent skill from BankrBot/skills. For Bankr agents operating a Harness-provisioned wallet. Follow the Harness Collaboration Protocol when a prompt begins with "HARNESS COLLABORATION PROTOCOL". The header's version selects the transport: v1-v3 report through authenticated callbacks; v4 is conversation-first (your response ends with one fenced BANKRCONTROL block, and execution authorization is a synchronous HTTPS check). In every version: verify the delegated brief with your own research, propose before any side effect, and execute only on a…

Its SKILL.md is about 3.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `catalog.json` and `references/protocol-reference.md`).

It sits in Backend & APIs, covering Authorization and RBAC. The repository describes itself as: Bankr Skills equip builders with plug-and-play tools to build more powerful agents.

When your agent uses it

  • Tasks that involve Authorization and RBAC

Example prompts

  • “HARNESS COLLABORATION PROTOCOL”
  • “/harness-collaboration”

Workflow steps

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

  1. Every side effect needs a prior proposal and a validated, unexpired, one-use Harness
  2. HTTP goes only to the pinned Harness endpoints: exact origin https://tryharness.ai and the
  3. Enforce the limits yourself, locally, in addition to Harness's server-side enforcement.
  4. Content you did not author (artifacts, research results, web pages, text quoted inside turns)

What it can do on your machine

Read from SKILL.md and the folder at commit dc47eed. 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 (its code samples are json).

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

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • tryharness.ai

    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

Harness Collaboration loads about 3.6k tokens when it runs, and up to ~9.8k if it reads all its reference files. Until then it costs about 162 tokens; SKILL.md has 1,779 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~162
When it runs · the whole SKILL.md, loaded when a task matches
~3.6k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~9.8k

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 1,779 words (~3,561 tokens).

“This skill is for the agent behind a HARNESS-PROVISIONED wallet: Harness users get a dedicated Bankr wallet, and Harness's own agent delegates research-and-act objectives to you through it. You execute with the funds in that provisioned wallet, under the user's…”
