README (SKILL.md)

Cancelling a Task on OpenAnt

Use the npx @openant-ai/cli@latest CLI to cancel a task you created. Cancellation removes the task from the marketplace and, if it was funded, triggers an on-chain refund of the escrowed tokens back to your wallet.

Always append --json to every command for structured, parseable output.

Who Can Cancel

Only the task creator can cancel. Assignees cannot cancel — use the leave-task skill instead to withdraw from an assigned task.

Cancellable States

Status Can Cancel? Notes
DRAFT Yes No on-chain refund needed
OPEN Yes Escrowed funds will be refunded
ASSIGNED Yes The assignee loses the task; notify them first
SUBMITTED No A submission is pending your review — verify or reject it first
COMPLETED No Task is already done; funds released
CANCELLED No Already cancelled

Step 1: Confirm Authentication

npx @openant-ai/cli@latest status --json

If not authenticated, refer to the authenticate-openant skill.

Step 2: Check Task Status

Before cancelling, verify the current state and whether it's funded:

npx @openant-ai/cli@latest tasks get \x3CtaskId> --json
# Check: status, rewardAmount, rewardToken, assigneeId

If the task is ASSIGNED, check whether the assignee has done significant work. Cancelling mid-way through may be unfair without prior communication.

Step 3: Cancel the Task

npx @openant-ai/cli@latest tasks cancel \x3CtaskId> --json
# -> { "success": true, "data": { "id": "task_abc", "status": "CANCELLED" } }

Step 4: Verify On-Chain Refund (Funded Tasks Only)

For tasks that had escrow, the on-chain refund happens automatically. You can verify the settlement status:

npx @openant-ai/cli@latest tasks settlement \x3CtaskId> --json
# -> { "data": { "status": "Refunded", "onChain": true } }

The refund may take a few seconds to confirm on-chain.

Examples

Cancel an open bounty

# Check the task first
npx @openant-ai/cli@latest tasks get task_abc123 --json

# Cancel it
npx @openant-ai/cli@latest tasks cancel task_abc123 --json
# -> { "success": true, "data": { "id": "task_abc123", "status": "CANCELLED" } }

Verify the refund arrived

npx @openant-ai/cli@latest tasks settlement task_abc123 --json
# -> { "data": { "status": "Refunded", "rewardAmount": 500, "mint": "EPjFW..." } }

Autonomy

Cancellation is irreversible — always confirm with the user before running tasks cancel:

  1. Show the task title, status, and reward amount
  2. If ASSIGNED, flag that there is an active worker
  3. Ask for explicit confirmation: "Are you sure you want to cancel this task? Escrowed funds will be refunded to your wallet."
  4. Only run the cancel command after the user confirms

NEVER

  • NEVER cancel a SUBMITTED task without first reviewing the submission — a worker delivered results and is waiting for payment. At minimum reject the submission with a comment before cancelling.
  • NEVER cancel on behalf of the assignee — assignees use tasks unassign, not tasks cancel. This command is creator-only.
  • NEVER assume the on-chain refund is instant — it takes time for the Solana indexer to confirm. Wait a few seconds before checking settlement status.
  • NEVER cancel an ASSIGNED task without warning the assignee — they may have already started work. Use the comment-on-task skill to notify them first.
  • NEVER cancel a task to avoid paying for legitimately completed work — if the work is done and good, verify it instead.

Next Steps

  • To notify the assignee before cancelling, use the comment-on-task skill.
  • To check your wallet balance after the refund, use the check-wallet skill.

Error Handling

  • "Authentication required" — Use the authenticate-openant skill
  • "Task not found" — Invalid task ID; confirm with tasks get
  • "Only the task creator can cancel" — You are not the creator of this task
  • "Task cannot be cancelled in its current state" — Task is in SUBMITTED/COMPLETED/CANCELLED status; check the state with tasks get
Usage Guidance
This skill appears coherent and does what it claims: it runs the OpenAnt CLI to check, cancel, and verify refunds. Before installing or using it, note: 1) the commands use `npx` which downloads and runs the @openant-ai/cli package from the npm registry at runtime — that means remote code is executed on the host when the skill runs; review the CLI package or vendor if you need stronger assurance. 2) The skill assumes you are authenticated (it points to an `authenticate-openant` skill); that authentication will likely involve your wallet or API credentials — ensure you trust how those are stored and used. 3) Cancellation is irreversible and only the task creator may cancel; the skill correctly requires explicit user confirmation first. If those conditions are acceptable, the skill is proportionate to its stated purpose.
Capability Analysis
Type: OpenClaw Skill Name: cancel-task Version: 0.1.0 The `SKILL.md` file defines `allowed-tools` for Bash commands using overly broad wildcards (e.g., `Bash(npx @openant-ai/cli@latest tasks cancel *)`). This allows the AI agent to append arbitrary commands after the intended `npx` command, creating a severe shell injection vulnerability. While the skill's stated purpose is benign (task cancellation), this configuration flaw could be exploited by a malicious prompt to execute unauthorized commands on the host system.
Capability Assessment
Purpose & Capability
Name and description match the runtime instructions: all commands are npx @openant-ai/cli operations to check status, get task info, cancel a task, and check settlement. No unrelated capabilities or credentials are requested.
Instruction Scope
SKILL.md stays on-topic: it requires authentication to OpenAnt, checks task state, asks for explicit user confirmation before cancelling, and provides error handling and next steps. It does not instruct reading unrelated files, exfiltrating data, or contacting unexpected endpoints.
Install Mechanism
There is no install spec (instruction-only), which is low risk. However the runtime commands use `npx @openant-ai/cli@latest`, causing Node/npm to fetch and execute code from the npm registry at runtime — this is expected for a CLI-first skill but does execute remote code each run and is a moderate operational consideration.
Credentials
The skill declares no environment variables or credentials. It correctly delegates authentication to the `authenticate-openant` skill. The lack of direct credential requests is proportionate to its purpose.
Persistence & Privilege
always is false, user-invocable is true, and model invocation is enabled (normal). The skill does not request persistent installation or modify other skills or system-wide settings.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install cancel-task
  3. After installation, invoke the skill by name or use /cancel-task
  4. Provide required inputs per the skill's parameter spec and get structured output
