charset=UTF-8 Content-Transfer-Encoding: 8bit Work CLI's mission is "revolutionary mixed human-agent teams where everyone operates on the same level," but currently humans have a first-class assignee field while agents are relegated to label conventions (agent:X). This creates verbose queries, no semantic distinction, no validation, and poor visibility. Changes: - Added agent?: string field to WorkItem type (parallel to assignee) - Added agent to CreateWorkItemRequest and UpdateWorkItemRequest - Added --agent flag to create and set commands - Added 'agent' option to unset command - Display agent field in get command output - Added agent field support to query engine (WHERE agent=X filtering) - Local-FS adapter stores agent in frontmatter - GitHub adapter maps agent ↔ agent:* label (backward compatible) - Added comprehensive tests for agent field functionality Fixes #1572 --- src/adapters/github/mapper.ts | 18 ++++++- src/adapters/local-fs/index.ts | 2 + src/adapters/local-fs/storage.ts | 1 + src/cli/commands/create.ts | 4 ++ src/cli/commands/get.ts | 1 + src/cli/commands/set.ts | 5 ++ src/cli/commands/unset.ts | 5 +- src/core/query.ts | 4 ++ src/types/work-item.ts | 3 ++ tests/unit/core/query-focused.test.ts | 67 +++++++++++++++++++++++++++ tests/unit/types/work-item.test.ts | 2 + 11 files changed, 110 insertions(+), 2 deletions(-) diff --git a/src/adapters/github/mapper.ts b/src/adapters/github/mapper.ts index 7957cd7..9899210 100644 --- a/src/adapters/github/mapper.ts +++ b/src/adapters/github/mapper.ts @@ -9,6 +9,15 @@ import { GitHubIssue } from './types.js'; * Converts GitHub Issue to WorkItem */ export function githubIssueToWorkItem(issue: GitHubIssue): WorkItem { + // Extract agent from agent:* label pattern + const agentLabel = issue.labels.find(label => label.name.startsWith('agent:')); + const agent = agentLabel ? agentLabel.name.substring(6) : undefined; + + // Filter out agent:* labels from the labels array + const filteredLabels = issue.labels + .map(label => label.name) + .filter(name => !name.startsWith('agent:')); + return { id: issue.number.toString(), kind: 'task', // Default kind, could be enhanced with label mapping @@ -17,7 +26,8 @@ export function githubIssueToWorkItem(issue: GitHubIssue): WorkItem { state: issue.state === 'open' ?

The previous implementation correctly handled agent field creation but silently ignored agent field updates. This fix: - Fetches current issue labels when agent is being updated - Removes all agent:* labels from current labels - Adds new agent:* label if agent is provided (or clears if undefined) - Preserves other labels during agent updates This ensures agent field updates work correctly via GitHub adapter, completing the first-class agent support feature. --- src/adapters/github/index.ts | 17 ++++++++++++++++- 1 file changed, 16 insertions(+), 1 deletion(-) diff --git a/src/adapters/github/index.ts b/src/adapters/github/index.ts index a0fe2bf..5bfd90e 100644 --- a/src/adapters/github/index.ts +++ b/src/adapters/github/index.ts @@ -139,7 +139,22 @@ export class GitHubAdapter implements WorkAdapter { updates.body = request.description; } - if (request.labels !== undefined) { + // Handle agent field updates by managing agent:* labels + if (request.agent !== undefined) { + // Fetch current issue to get existing labels + const currentIssue = await this.apiClient.getIssue(issueNumber); + const currentLabels = currentIssue.labels.map(l => l.name); + + // Remove all agent:* labels + const labelsWithoutAgent = currentLabels.filter(name => !name.startsWith('agent:')); + + // Add new agent label if provided (clearing if null/undefined) + if (request.agent) { + labelsWithoutAgent.push(`agent:${request.agent}`); + } + + updates.labels = labelsWithoutAgent; + } else if (request.labels !== undefined) { updates.labels = [...request.labels]; } From b971b84dfb9bea33daf46fb7cd98cd163738431e Mon Sep 17 00:00:00 2001 From: Tom Brandenburg Date: Sat, 7 Feb 2026 22:05:32 +0100 Subject: [PATCH 5/5] Archive investigation for issue #1572 --- .claude/PRPs/issues/{ => completed}/issue-1572.md | 0 1 file changed, 0 insertions(+), 0 deletions(-) rename .claude/PRPs/issues/{ => completed}/issue-1572.md (100%) diff --git a/.claude/PRPs/issues/issue-1572.md b/.claude/PRPs/issues/completed/issue-1572.md similarity index 100% rename from .claude/PRPs/issues/issue-1572.md rename to .claude/PRPs/issues/completed/issue-1572.md
