+# Taskmarket Action Provider
+
+This directory contains a read-only AgentKit action provider for discovering and inspecting public, funded work on [Taskmarket](https://taskmarket.dev).
+
+## Actions
+
+### `list_tasks`
+
+Lists open Taskmarket tasks with bounded filters for:
+
+- task mode;
+- minimum gross USDC reward;
+- deadline window;
+- result count.
+
+Results include gross and net rewards, deadline, submission count, requester address, escrow transaction hash and the canonical task URL.
+
+### `get_task`
+
+Gets one task by its 32-byte task identifier and returns:
+
+- escrow and requester references;
+- gross reward, net reward and platform fee;
+- phase and submission-window status;
+- worker-relevant next actions;
+- canonical task URL.
+
+## Safety
+
+Both actions are deliberately read-only and network-independent. The provider:
+
+- never creates or connects a wallet;
+- never signs or submits a transaction;
+- never claims, bids on or submits work;
+- never accepts a task or releases escrow;
+- makes its own data requests only to the fixed public API host `https://api.taskmarket.dev`;
+- inherits AgentKit's existing action-invocation analytics wrapper, which reports action metadata to Coinbase but does not include Taskmarket descriptions or action arguments;
+- validates task identifiers before constructing detail URLs;
+- labels third-party task descriptions as untrusted content.
+
+A future write integration should be a separate change with explicit user authorisation and wallet spending controls.
+
+## Usage
+
+```python
+import json
+
+from coinbase_agentkit import taskmarket_action_provider
+
+provider = taskmarket_action_provider()
+
+open_work = json.loads(
+    provider.list_tasks(
+        {
+            "mode": "bounty",
+            "min_reward_usdc": "1",
+            "deadline_hours": 168,
+            "limit": 10,
+        }
+    )
+)
+
+if open_work["tasks"]:
+    task = json.loads(provider.get_task({"task_id": open_work["tasks"][0]["id"]}))
+```
+
+## Tests
+
+From `python/coinbase-agentkit`:
+
+```bash
+pytest tests/action_providers/taskmarket -q
+```
