Backlog (Future Milestones)

[ ] Milestone M26: Output Format Standardization & Stream Separation (v0.26.0)

Goal: Standardize output formatting across all commands by separating data (stdout) from human messages (stderr), fixing machine-readability issues, and extending format support to all read/write commands following Unix conventions.

Reference: See OUTPUT_STREAMS_PROPOSAL.md for complete design rationale and technical details.

Requirements

Separate data output (stdout) from human messages (stderr) for all commands
Route all progress, success, info, and warning messages to stderr via console.error
Extend --format json|tsv|table support to all read commands (view, dependencies list)
Add --format json support to mutation commands (create, update) for automation
Fix TSV format issues: add proper tab escaping, remove field truncation inconsistencies
Consolidate duplicated table/TSV formatting code into unified implementation
Add global --quiet flag to suppress non-error messages
Maintain 100% backward compatibility - no breaking changes to default output
Follow Unix conventions and best practices from kubectl, gh, aws-cli, jq

Out of Scope

YAML format support (future consideration)
CSV format (TSV is sufficient for now)
NDJSON streaming format (future consideration)
Color output detection and auto-disable when piped (future enhancement)
Verbose mode (--verbose flag) - defer to future milestone
Changes to interactive mode output (Ink components handle their own rendering)

[x] Milestone M15: Issue Commands - Core CRUD (v0.24.0)

Goal: Implement comprehensive issue management with create, update, view, and list commands for Linear issues. This is a meta-milestone tracking the overall issue command implementation across multiple phased releases.

Clarified Behaviors (Updated 2025-10-28)

This section documents key design decisions and clarified behaviors for M15 implementation:

1. Active Filter Definition (M15.5)

"Active" issues are those without completion or cancellation timestamps
This typically includes states with type: triage, backlog, unstarted, started
Explicitly excludes issues that have been completed or canceled
Archived issues excluded separately via archivedAt field

2. Filter Precedence Logic (M15.5)

Assignee: Explicit --assignee overrides "me" default (no --all-assignees needed). --all-assignees removes filter entirely.
Team: Explicit --team overrides defaultTeam from config

3. Config Validation (M15.3)

If defaultTeam and defaultProject are both set but belong to different teams: ERROR
Error message: "defaultProject '{name}' belongs to team '{team}' but issue team is '{issueTeam}'. Use --project to specify compatible project or update config."

4. Cycle Validation (M15.3, M15.4)

Cycles support both UUID format AND alias resolution (via M15.1-T22)
Validate format: must be valid UUID OR resolve to cycle alias
Reject invalid formats with helpful error

5. Update Options Validation (M15.4)

"No options provided" error counts only data-modifying flags
Excludes: --web (mode flag)
Counts: title, description, priority, estimate, state, dates, assignments, labels, subscribers, trash/untrash, team, project, cycle, parent

6. Member Resolution (M15.1)

Full support for: ID, alias, email, and display name lookup
Email lookup via Linear API user search (exact match)
Display name lookup with disambiguation if multiple matches
Error messages show available options or "Did you mean...?" suggestions

7. Project Resolution (M15.1)

Support: ID, alias, and name (exact + fuzzy/partial matching)
Ambiguous names show list of matching projects for disambiguation

8. Label/Subscriber Mutual Exclusivity (M15.4)

--labels conflicts with --add-labels or --remove-labels (ERROR)
--add-labels AND --remove-labels together is ALLOWED (add first, then remove)
Same logic applies to --subscribers, --add-subscribers, --remove-subscribers

Regression Testing:

Re-run M15.1 infrastructure tests to ensure no regressions (no changes to M15.1 code)

Bug Fixes (v0.24.0-alpha.2.1):

[M15.2-BUG-01] Fix child issue state display - child states always showed "Unknown" instead of actual state name (src/commands/issue/view.ts:188-196)
- Root cause: Incorrect defensive check typeof child.state === 'string' was always false
- Fix: Removed defensive check; linear-client.ts already properly awaits and returns state as string
- See BUGS_M15-2.md for detailed analysis
[M15.2-BUG-02] Add validation for conflicting --json and --web flags (src/commands/issue/view.ts:52-57)
- Root cause: No validation for mutually exclusive output modes
- Fix: Added mutual exclusivity check with clear error message
- Follows CLI best practices (similar to git, docker)
- See BUGS_M15-2.md for detailed analysis

Performance Optimization (v0.24.0-alpha.2.1):

[M15.2-PERF-01] Replace SDK lazy loading with custom GraphQL query in getFullIssueById() (src/lib/linear-client.ts:1334-1543)
- Problem: Linear SDK lazy loading caused 11+ separate API calls per issue view (state, team, assignee, project, cycle, parent, children, labels, subscribers, creator)
- Impact: 1-2 second latency, 11x rate limit consumption (136 views/hour vs 1,500 possible)
- Solution: Single comprehensive GraphQL query using client.client.rawRequest()
- Results:
  - 11x reduction in API calls (11+ → 1)
  - 5-10x performance improvement (1-2s → 100-200ms)
  - 11x rate limit efficiency (136 → 1,500 views/hour)
  - Eliminated N+1 pattern for child issue states (bonus fix)
- Pattern: Consistent with issue list command implementation (lines 1042-1136)
- See BUGS_M15-2.md for detailed analysis and Linear SDK investigation
[M15.2-PERF-02] Replace SDK lazy loading with custom GraphQL query in getIssueComments() (src/lib/linear-client.ts:1545-1616)
- Problem: Linear SDK lazy loading caused 2 + N API calls per comment fetch (issue + comments + N user fetches)
- Impact: For issues with 10 comments: 12 API calls, significant latency with --show-comments flag
- Solution: Single GraphQL query fetching comments with nested user data
- Results:
  - (2 + N) → 1 API call (e.g., 12 → 1 for 10 comments)
  - 10x+ improvement for issues with many comments
  - Users are pre-fetched with comments collection
[M15.2-PERF-03] Replace SDK lazy loading with custom GraphQL query in getIssueHistory() (src/lib/linear-client.ts:1618-1720)
- Problem: Linear SDK lazy loading caused 2 + 7N API calls per history fetch (7 awaits per entry: actor, fromState, toState, fromAssignee, toAssignee, addedLabels, removedLabels)
- Impact: For issues with 10 history entries: 72 API calls! Extremely slow with --show-history flag
- Solution: Single GraphQL query fetching history with all nested relationships
- Results:
  - (2 + 7N) → 1 API call (e.g., 72 → 1 for 10 history entries)
  - 70x+ improvement for issues with extensive history
  - All relationships pre-fetched in single query
[M15.2-PERF-04] Replace SDK lazy loading with custom GraphQL query in getAllIssueLabels() (src/lib/linear-client.ts:3202-3273)
- Problem: Linear SDK lazy loading caused 1 + N API calls when fetching all issue labels (1 for labels + N team fetches)
- Impact: For workspaces with 20 labels: 21 API calls for issue-labels list command
- Solution: Single GraphQL query fetching labels with nested team data
- Results:
  - (1 + N) → 1 API call (e.g., 21 → 1 for 20 labels)
  - ~95% reduction for typical workspaces
  - Team data pre-fetched with labels collection
[M15.2-PERF-05] Replace SDK lazy loading with custom GraphQL query in getAllWorkflowStates() (src/lib/linear-client.ts:2986-3072)
- Problem: Linear SDK lazy loading caused 1 + N API calls when fetching all workflow states (1 for teams + N state fetches per team)
- Impact: For workspaces with 10 teams: 11 API calls for workflow-states list command
- Solution: Single GraphQL query fetching teams with nested states data
- Results:
  - (1 + N) → 1 API call (e.g., 11 → 1 for 10 teams)
  - ~90% reduction for typical workspaces
  - States pre-fetched with teams collection
[M15.2-PERF-06] Replace SDK lazy loading with custom GraphQL query in getFullProjectDetails() (src/lib/linear-client.ts:2669-2800)
- Problem: Linear SDK lazy loading caused ~10 API calls per project view (project + getProjectById + initiatives + teams + template + milestones + issues)
- Impact: For project view command: ~10 API calls causing 1-2 second latency
- Solution: Single comprehensive GraphQL query fetching all project data and relationships upfront
- Results:
  - ~10 → 1 API call (90% reduction)
  - 5-10x performance improvement (1-2s → 100-200ms estimated)
  - All data (basic info, initiatives, teams, template, milestones, issues) pre-fetched
  - Used by src/commands/project/view.ts
[M15.2-PERF-07] Replace SDK lazy loading with custom GraphQL query in getProjectById() (src/lib/linear-client.ts:2519-2598)
- Problem: Linear SDK lazy loading caused 3 API calls per project fetch (project + initiatives + teams)
- Impact: Used in 11 locations (alias commands, config, project-resolver); each call makes 3 requests
- Solution: Single GraphQL query fetching project with nested initiatives and teams
- Results:
  - 3 → 1 API call (67% reduction)
  - 3x performance improvement for all project lookups
  - Initiatives and teams pre-fetched with project data
  - Used by: alias/edit.tsx, alias/list.ts, config/set.ts, project-resolver.ts, aliases.ts (11 total locations)

Combined Impact:

Issue view with --show-comments and --show-history flags:
- Before: 11+ (view) + 12 (comments) + 72 (history) = 95+ API calls for typical issue
- After: 1 (view) + 1 (comments) + 1 (history) = 3 API calls
- 32x reduction in API calls for full issue inspection
- Sub-second performance instead of 5-10 second delays
List commands optimization:
- issue-labels list: Before 21 calls → After 1 call (~95% reduction)
- workflow-states list: Before 11 calls → After 1 call (~90% reduction)
- Instant loading instead of visible delays
View commands optimization:
- project view: Before ~10 calls → After 1 call (90% reduction)
- issue view: Before 11+ calls → After 1 call (91% reduction)
- Instant loading for all view commands
Project utility optimization:
- getProjectById(): Before 3 calls → After 1 call (67% reduction)
- Used in 11 locations (alias, config, resolvers)
- Improves performance across multiple commands
Overall session: 7 functions optimized, eliminating all major N+1 query patterns
Rate limit impact: Massive improvement in API quota efficiency across all commands

[x] Milestone M15.3: Issue Create Command (v0.24.0-alpha.3)

Goal: Implement full-featured issue creation with 23+ options following project command patterns

Performance Note: Minimize validation API calls. Use cached entity data where possible (entity-cache). Avoid validating every field with separate API requests.

Note: Performance optimization achieved through entity-cache usage (see src/commands/issue/create.ts). Explicit performance tests deferred to M15.5 where more critical.

Requirements

Create issues with title (required) and team (required unless defaultTeam configured)
Support all content, priority, workflow, date, assignment, and organization options
Implement auto-assignment to creator by default
Support config defaults (defaultTeam, defaultProject)
Support all alias types (team, workflow-state, issue-label, member, project)
Mutual exclusivity: --description vs --description-file
Web mode to open created issue
Efficient validation: Batch lookups, use cache, avoid per-field API calls

Out of Scope

Interactive creation mode (see M15.6 for interactive -I support)
Issue templates UI (basic --template support included)

[x] Milestone M15.5: Issue List Command (v0.24.0-alpha.5)

Goal: Implement comprehensive issue listing with smart defaults and extensive filtering

⚠️ CRITICAL PERFORMANCE REQUIREMENT: This milestone requires extreme care to avoid N+1 query problems and GraphQL complexity warnings. See "Performance & Query Optimization" section below.

Requirements

List issues with smart defaults (assignee=me, defaultTeam, active only)
Support override flag to bypass assignee default: --all-assignees
Note: Team filter uses explicit --team value (cleaner UX than --all-teams flag)
Implement extensive filtering: team, assignee, project, initiative, state, priority, labels
Support relationship filters (parent, cycle, no-parent)
Support status filters (active, completed, canceled, all-states, archived)
Implement full-text search
Support multiple output formats (table, JSON, TSV)
Implement sorting and limiting
Web mode to open Linear with filters applied
MUST be performant: Single efficient GraphQL query, no N+1 patterns

Out of Scope

Interactive list/browser mode (see M15.6 for interactive -I support)
Bulk operations on listed issues

Performance & Query Optimization

⚠️ CRITICAL LESSONS FROM PROJECT LIST (M20):

The project list command initially had severe N+1 query problems:

Made separate API calls for EVERY project to fetch related data
Resulted in 50+ API calls for listing 50 projects
Extremely slow performance (10-30 seconds for simple lists)
Hit Linear's GraphQL complexity limits with warnings
Poor user experience

ROOT CAUSE: Using Linear SDK's convenience methods that hide nested queries and make separate calls per item.

SOLUTION REQUIREMENTS FOR ISSUE LIST:

Single GraphQL Query Approach ⭐ REQUIRED
- Write custom GraphQL query that fetches ALL needed data in one request
- Use GraphQL fragments to include all display fields upfront
- Include nested relations (assignee, team, project, labels, etc.) in initial query
- Avoid Linear SDK's issue.assignee, issue.team patterns that trigger new queries

Query Structure

query IssueList($filter: IssueFilter, $first: Int) {
  issues(filter: $filter, first: $first) {
    nodes {
      id
      identifier
      title
      priority
      state {
        id
        name
        type
      }
      assignee {
        id
        name
        email
      }
      team {
        id
        key
        name
      }
      project {
        id
        name
      }
      labels {
        nodes {
          id
          name
        }
      }
      # All other needed fields
    }
  }
}

Implementation Strategy (✅ Completed in Phase 1)
- [M15.5-T00a] Research Linear's GraphQL schema for issues query
- [M15.5-T00b] Design single-query approach that fetches all display data
- [M15.5-T00c] Consider direct GraphQL vs Linear SDK (used rawRequest for full control)
- [M15.5-T00d] Implement query batching if needed for alias resolution (not needed in Phase 1)
- [M15.5-T00e] Add performance logging to detect any N+1 patterns during testing (api-call-tracker.ts)
Validation Strategy (Phase 1 Status: No validation needed yet)
- Smart validation will be added in Phase 2 for filters
- Will use cached data from entity-cache
- Will avoid per-issue validation loops
Testing Requirements (✅ Completed in Phase 1)
- [M15.5-TS00a] Test with 100+ issues to verify performance (2 seconds for 250 issues)
- [M15.5-TS00b] Log all GraphQL queries and verify single-query pattern (DEBUG mode confirmed)
- [M15.5-TS00c] Measure total API calls (verified: 1 API call for basic list)
- [M15.5-TS00d] Verify no GraphQL complexity warnings from Linear API (no warnings observed)

REFERENCE IMPLEMENTATIONS:

❌ Bad: src/commands/project/list.tsx (initial implementation - slow, N+1)
✅ Good: After M20 optimization (need to reference that implementation)

KEY PRINCIPLE: If you're iterating over results and making API calls inside the loop, you're doing it wrong.

Pagination Requirements

⚠️ LINEAR API LIMITS:

Default: 50 results per query
Maximum: 250 results per query (hard limit)
For 250+ results: Must use cursor-based pagination

PAGINATION STRATEGY (from M20/M21 project list optimization):

Page Size Logic

// Default: 50 (user-friendly default)
// With --limit N: Use min(N, 250)
// With --all: Use 250 (maximum efficiency)
const pageSize = filters?.fetchAll ? 250 : Math.min(filters?.limit || 50, 250);

Cursor-Based Pagination Loop

let issues: any[] = [];
let cursor: string | null = null;
let hasNextPage = true;

while (hasNextPage && (fetchAll || issues.length < targetLimit)) {
  const response = await client.rawRequest(query, {
    filter: graphqlFilter,
    first: pageSize,
    after: cursor  // Cursor for next page
  });

  issues.push(...response.data.issues.nodes);
  hasNextPage = response.data.issues.pageInfo.hasNextPage;
  cursor = response.data.issues.pageInfo.endCursor;

  // Stop early if we have enough (when not --all)
  if (!fetchAll && issues.length >= targetLimit) break;
}

Query Must Include pageInfo

query IssueList($filter: IssueFilter, $first: Int, $after: String) {
  issues(filter: $filter, first: $first, after: $after) {
    nodes { ... }
    pageInfo {
      hasNextPage
      endCursor
    }
  }
}

Performance Considerations
- Use 250 per page for --all flag (5x faster than 50)
- Stop early when limit reached (don't over-fetch)
- Show progress for large result sets if appropriate

REFERENCE: src/lib/linear-client.ts lines 714-823 (getAllProjects pagination implementation)

Tests & Tasks

=== PHASE 1 COMPLETE (v0.24.0-alpha.5.1) ===

Performance Foundation & Pagination - COMPLETED

Phase 1 Verification:

npm run build succeeds (dist/index.js: 660.95 KB)
npm run typecheck passes (0 errors)
npm run lint passes (warnings only, no errors)
All 10 performance tests pass
Performance verified: 1 API call for listing 100 issues (not N+1)
Pagination verified: Early termination when limit reached
Debug mode confirms single-page fetch for limit ≤250

Phase 1 Deliverable:

$ agent2linear issue list --limit 100
Identifier  Title           State       Priority  Assignee  Team
BAN-277     Test Issue      Backlog     None      alan      BAN
...
Total: 100 issue(s)

# Performance: 1 API call, ~2 seconds for 100 issues

Next Phase: Phase 2 will add smart defaults (assignee=me, defaultTeam, active filter) and core filtering options.

=== PHASE 2 COMPLETE (v0.24.0-alpha.5.2) ===

Smart Defaults + Core Filters - COMPLETED

Phase 2 Scope Adjustments:

✅ Initiative filtering deferred to Phase 3 (Linear's IssueFilter doesn't support direct initiative field)
✅ Simplified to core filters that map directly to Linear API

Phase 2 Verification:

npm run build succeeds (dist/index.js: 665.30 KB)
npm run typecheck passes (0 errors)
npm run lint passes (warnings only, no errors)
All Phase 1 performance tests pass (10/10)
Manual testing confirms smart defaults work correctly
Manual testing confirms filter overrides work (--all-assignees, --priority, etc.)
Performance maintained: Still 1 API call for basic list

Phase 2 Deliverable:

# Default: My active issues in default team
$ agent2linear issue list
Identifier  Title           State       Priority  Assignee  Team
BAN-273     Updated Title   Backlog     Urgent    steve     BAN
...
Total: 5 issue(s)

# Override assignee default
$ agent2linear issue list --all-assignees
[Shows all users' active issues]

# Filter by priority
$ agent2linear issue list --priority 1
[Shows only Urgent issues assigned to me]

# Show completed instead of active
$ agent2linear issue list --completed
[Shows completed issues assigned to me]

# Combine filters
$ agent2linear issue list --team backend --priority 2 --state todo
[Shows High priority Todo issues in backend team assigned to me]

Smart Defaults Confirmed:

✅ Assignee = current user ("me") unless --assignee or --all-assignees provided
✅ Team = defaultTeam from config (if set), overridden by --team
✅ Status = Active only (excludes completed/canceled) unless status filter provided
✅ Archived = Excluded unless --archived provided

Filter Precedence Verified:

✅ Explicit --assignee overrides "me" default (no --all-assignees needed)
✅ --all-assignees removes assignee filter entirely
✅ Explicit --team overrides defaultTeam
✅ Status filters (--completed, --canceled, --all-states) override active default

Next Phase: Phase 3 will add advanced filters (labels, search, relationships), output formats (JSON, TSV), sorting, and web mode.

=== PHASE 3 COMPLETE (v0.24.0-alpha.5) ===

Advanced Filters + Output Formats + Sorting + Web Mode - COMPLETED

Phase 3 Implementation Details:

Sorting Strategy
- Implemented client-side sorting after fetch (negligible performance impact for <1000 issues)
- Supports: priority (default), created, updated, due
- Sort order: asc or desc (default: desc)
- Smart handling of null values (issues without due dates go to end)
Output Formats
- table: Default tab-separated output with summary line
- json: Full JSON output for scripting (validated with jq)
- tsv: Tab-separated values for shell piping
Advanced Filters
- --label: Repeatable option for multiple labels (AND logic)
- --parent: Show sub-issues of specific parent (by identifier or UUID)
- --root-only: Show only root-level issues (no parent)
- --cycle: Filter by cycle
- --search: Full-text search in title and description
- Mutual exclusivity validation for --parent and --root-only
Web Mode
- --web: Opens Linear in browser with filters applied
- Constructs Linear URLs with team and filter hints
- Alternative to fetching when you want to interact in Linear UI
API Integration
- Uses Linear's GraphQL IssueFilter for server-side filtering
- Client-side sorting (Linear's GraphQL orderBy syntax not readily available)
- Maintains single-query performance pattern from Phase 1

Phase 3 Verification:

npm run build succeeds (dist/index.js: 671.33 KB)
npm run typecheck passes (0 errors)
npm run lint passes (43 warnings, 0 errors - no new issues)
All Phase 1 performance tests pass (10/10)
All Phase 3 advanced feature tests pass (15/15)
Performance maintained: Still 1 API call for list operations
Manual testing of sorting, formats, and filters

Phase 3 Deliverable:

[~] Milestone M15.6 (Original): Issue Interactive Enhancements

Status: RENUMBERED TO M25 (v0.25.0)

Reason: To release v0.24.0 with all non-interactive issue commands complete, interactive enhancements have been deferred to M25. This allows faster delivery of core functionality while planning interactive features for the next release.

See: Milestone M25 (v0.25.0) for the full implementation plan

Deprecated Milestones

The following milestones have been superseded by more detailed implementations:

[~] Milestone M19: Issue Creation & Management (v0.18.0)

Status: DEPRECATED - Replaced by M15 meta-milestone and M15.1-M15.6 detailed milestones

Reason: This milestone was originally planned as a single release but was later broken down into a more granular phased approach for better incremental delivery and testing. See M15 (v0.24.0) and its sub-milestones M15.1 through M15.6 for the current implementation plan.

Original Goal: Implement issue creation and management commands

Superseded By:

M15: Issue Commands - Core CRUD (v0.24.0) - Meta-milestone
M15.1: Issue Infrastructure & Foundation (v0.24.0-alpha.1)
M15.2: Issue View Command (v0.24.0-alpha.2)
M15.3: Issue Create Command (v0.24.0-alpha.3)
M15.4: Issue Update Command (v0.24.0-alpha.4)
M15.5: Issue List Command (v0.24.0-alpha.5)
M15.6: Issue Interactive Enhancements (v0.24.0)
