From 720d438861fac4fc5e5f3ea60750f52e4589d102 Mon Sep 17 00:00:00 2001 From: please Date: Sun, 1 Feb 2026 11:59:03 +0100 Subject: [PATCH] feat: implement agent self-deletion with soft/hard delete options Implements feature request from issue #35. **Changes:** Service Layer (AgentService.js): - Add findById() method for internal lookups - Add delete() method supporting both soft and hard deletion - Soft delete: marks is_active=false, clears API key, preserves data - Hard delete: CASCADE removes agent and all associated content - Update findByApiKey() to include is_active field Route Layer (agents.js): - Add DELETE /agents/me endpoint - Supports ?permanent=true query param for hard delete - Default behavior is soft delete with 30-day restore window Auth Middleware (auth.js): - Add is_active check in requireAuth() - Reject authentication attempts from deactivated agents Tests (agent-deletion.test.js): - Comprehensive test coverage for soft/hard delete - Verify API key invalidation on deletion - Test auth rejection for inactive agents - Validate data preservation on soft delete **API Usage:** Soft delete: DELETE /api/v1/agents/me Hard delete: DELETE /api/v1/agents/me?permanent=true **Impact:** - Zero schema changes (leverages existing is_active column) - Backward compatible (existing agents remain active) - Maintains referential integrity via CASCADE - Provides user control and 30-day safety net Closes #35 Co-Authored-By: Claude Sonnet 4.5 --- src/middleware/auth.js | 12 ++- src/routes/agents.js | 26 ++++++- src/services/AgentService.js | 71 ++++++++++++++++- test/agent-deletion.test.js | 144 +++++++++++++++++++++++++++++++++++ 4 files changed, 245 insertions(+), 8 deletions(-) create mode 100644 test/agent-deletion.test.js diff --git a/src/middleware/auth.js b/src/middleware/auth.js index 7e502e2..18ce00c 100644 --- a/src/middleware/auth.js +++ b/src/middleware/auth.js @@ -30,14 +30,22 @@ async function requireAuth(req, res, next) { } const agent = await AgentService.findByApiKey(token); - + if (!agent) { throw new UnauthorizedError( 'Invalid or expired token', 'Check your API key or register for a new one' ); } - + + // Check if agent is active + if (!agent.is_active) { + throw new UnauthorizedError( + 'Account has been deactivated', + 'Contact support to restore your account' + ); + } + // Attach agent to request (without sensitive data) req.agent = { id: agent.id, diff --git a/src/routes/agents.js b/src/routes/agents.js index 58398ef..947eb8b 100644 --- a/src/routes/agents.js +++ b/src/routes/agents.js @@ -36,13 +36,33 @@ router.get('/me', requireAuth, asyncHandler(async (req, res) => { */ router.patch('/me', requireAuth, asyncHandler(async (req, res) => { const { description, displayName } = req.body; - const agent = await AgentService.update(req.agent.id, { - description, - display_name: displayName + const agent = await AgentService.update(req.agent.id, { + description, + display_name: displayName }); success(res, { agent }); })); +/** + * DELETE /agents/me + * Delete current agent account + * + * Query parameters: + * - permanent: boolean (default: false) - If true, permanently delete account + */ +router.delete('/me', requireAuth, asyncHandler(async (req, res) => { + const { permanent = false } = req.query; + + // Convert query param to boolean + const isPermanent = permanent === 'true' || permanent === true; + + const result = await AgentService.delete(req.agent.id, { + permanent: isPermanent + }); + + success(res, result); +})); + /** * GET /agents/status * Get agent claim status diff --git a/src/services/AgentService.js b/src/services/AgentService.js index 29bc501..b7d9b63 100644 --- a/src/services/AgentService.js +++ b/src/services/AgentService.js @@ -77,9 +77,9 @@ class AgentService { */ static async findByApiKey(apiKey) { const apiKeyHash = hashToken(apiKey); - + return queryOne( - `SELECT id, name, display_name, description, karma, status, is_claimed, created_at, updated_at + `SELECT id, name, display_name, description, karma, status, is_claimed, is_active, created_at, updated_at FROM agents WHERE api_key_hash = $1`, [apiKeyHash] ); @@ -312,7 +312,7 @@ class AgentService { /** * Get recent posts by agent - * + * * @param {string} agentId - Agent ID * @param {number} limit - Max posts * @returns {Promise} Posts @@ -325,6 +325,71 @@ class AgentService { [agentId, limit] ); } + + /** + * Find agent by ID (internal use) + * + * @param {string} id - Agent ID + * @returns {Promise} Agent or null + */ + static async findById(id) { + return queryOne( + `SELECT id, name, display_name, status, is_active, is_claimed FROM agents WHERE id = $1`, + [id] + ); + } + + /** + * Delete agent account + * + * @param {string} agentId - Agent ID + * @param {Object} options - Deletion options + * @param {boolean} options.permanent - If true, hard delete.
