What is manage-delegates?

A tool for checking and managing Harness Delegates, which are services that connect Harness to the systems where its work runs. It also handles the registration tokens used to connect them.

Use it to list delegates, check their status and heartbeats, create or revoke registration tokens, and find delegates linked to a token.

It removes the need to inspect delegate health and token details through separate manual checks. It helps identify unhealthy, disconnected, or incorrectly associated delegates.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00087	$0.00998
Opus 5	$0.00044	$0.00499
Sonnet 5	$0.00017	$0.00200
Haiku 4.5	$0.00009	$0.00100

Security

Grade A, and why

manage-delegates scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Manage Delegates

Monitor delegate health and manage registration tokens via MCP.

Instructions

Step 1: List Delegates

List all delegates in the account to check health and connectivity:

Call MCP tool: harness_list
Parameters:
  resource_type: "delegate"

This returns all delegates with their status, version, connectivity, and last heartbeat. Delegates are account-scoped -- no org/project needed.

Step 2: List Delegate Tokens

Call MCP tool: harness_list
Parameters:
  resource_type: "delegate_token"
  org_id: "<organization>"
  project_id: "<project>"

Filter by name or status:

Call MCP tool: harness_list
Parameters:
  resource_type: "delegate_token"
  name: "prod-token"
  status: "ACTIVE"

Step 3: Get Token Details

Call MCP tool: harness_get
Parameters:
  resource_type: "delegate_token"
  resource_id: "<token_name>"
  org_id: "<organization>"
  project_id: "<project>"

Step 4: Create a Token

Call MCP tool: harness_create
Parameters:
  resource_type: "delegate_token"
  org_id: "<organization>"
  project_id: "<project>"
  body:
    name: "prod-delegate-token"

Step 5: Find Delegates for a Token

Call MCP tool: harness_execute
Parameters:
  resource_type: "delegate_token"
  action: "get_delegates"
  resource_id: "<token_name>"
  org_id: "<organization>"
  project_id: "<project>"

Step 6: Revoke a Token

Call MCP tool: harness_execute
Parameters:
  resource_type: "delegate_token"
  action: "revoke"
  resource_id: "<token_name>"
  org_id: "<organization>"
  project_id: "<project>"

Step 7: Delete a Token

Call MCP tool: harness_delete
Parameters:
  resource_type: "delegate_token"
  resource_id: "<token_name>"
  org_id: "<organization>"
  project_id: "<project>"

Resource Types

Resource Type	Scope	Operations	Description
`delegate`	Account	list	List delegates with health status
`delegate_token`	Project	list, get, create, delete + revoke, get_delegates actions	Manage registration tokens

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
