+# Consolidated Research Findings — 13 Reference Repos vs jcode
+
+> **Generated from**: PARITY.md, MASTER_UI.md, .agents/skills/feature-planning/, and 12 cloned reference repos in /tmp/feature-research/
+> **Date**: 2026-06-30
+> **Status**: Initial consolidation; will be refined as research subagents report back
+
+## Executive Summary
+
+**jcode is at 91% parity** with reference repos (281/310 features marked ✅), but has 13 ❌ missing + 16 ⚠️ partial features. The biggest gaps are:
+1. **Provider System** (Section A) — needs 4-axis Route architecture
+2. **Plugin System hardening** (Section B) — needs V2 capability chain
+3. **Tools** (Section C) — DAP, tree-sitter code-map, prompt variants
+4. **Multi-agent orchestration** (Section D) — Agent Arena, Ferment plans
+5. **TUI features** (Section G) — file browser, MCP/LSP status panels

+# Goal-Driven(jcode Feature Implementation) System
+
+## 🎯 Goal
+
+**Implement all missing features from 13 reference AI coding agent repos as individual PRs against `master`, each accompanied by a detailed planning markdown file.**
+
+Each PR must:
+1. Have base branch = `master`
+2. Include a plan markdown file (`docs/pr-plans/<ID>-<name>.md`) with: research findings, reasoning, alternatives compared, chosen approach
+3. Pass `cargo build` and `cargo test`
+4. Update PARITY.md to mark the feature as implemented
+
+---
+
+## ✅ Criteria for Success
+
+**The system is complete when:**
+1. All P0 features are implemented and merged
+2. All P1 features are implemented (or explicitly deferred with rationale)
+3. PARITY.md §XIV (Reference Repo Gaps) shows all P0/P1 items marked ✅ or ❌(skipped)
+4. The PR backlog (`docs/PR_BACKLOG.md`) is updated with actual status per feature
+5. Each implemented feature has a plan file at `docs/pr-plans/<ID>-<name>.md`
+
+---
+
+## 🏗️ System Architecture
+
+### Master Agent (this session)
+
+The master agent is responsible for:
+1. **Supervising** the implementation subagents
+2. **Checking progress** every 5 minutes
+3. **Restarting inactive** subagents
+4. **Evaluating** whether success criteria are met
+5. **NOT stopping** until user manually stops
+
+### Implementation Subagents
+
+Each implementation subagent handles ONE feature PR:
+- Reads the plan file template at `docs/pr-plans/<ID>-<name>.md`
+- Clones/checkouts the relevant reference repo at `/tmp/feature-research/<repo>`
+- Compares against jcode's actual implementation
+- Writes the plan markdown (research, reasoning, alternatives, chosen approach)
+- Implements the feature
+- Runs tests
+- Opens a PR with proper description
+- Updates the backlog
+
+---
+
+## 📋 Workflow
+
+### Step 1 — Prioritized Queue
+
+Features are processed in this order (from `docs/PR_BACKLOG.md`):
+
+```
+Phase 1 (Foundation - P0):
+  A1 → A2 → A3 → A4 → A5 → B1
+
+Phase 2 (Core Ecosystem - P1):
+  A6 → A7 → A8 → A9 → A10 → B2 → B3 → C2 → C3 → C14 → D3 → D4 → D6 → E1 → E2 → F1
+
+Phase 3 (Polish - P1-P2):
+  A11 → A12 → A16 → A17 → B4 → B7 → C4 → C6 → C15 → C16 → C20 → D5 → G1 → G2 → G3 → G6 → G7 → G8
+
+Phase 4 (Long Tail - P2-P3):
+  Remaining P2/P3 items
+```
+
+### Step 2 — Implementation Subagent Task
+
+For each feature, spawn an implementation subagent with:
+
+```
+## Task for Feature: <feature-name> (<ID>)
+
+### Context
+- Feature description: <from PR_BACKLOG.md>
+- Source repos: <from PR_BACKLOG.md>
+- Priority: <P0/P1/P2/P3>
+- Effort: <S/M/L/XL>
+- Plan file: docs/pr-plans/<ID>-<name>.md
+- Branch name: feat/<ID>-<short-name>
+
+### Research Phase
+1. Check /tmp/feature-research/<repo>/ for cloned reference code
+2. If not cloned: git clone --depth=1 <repo_url> /tmp/feature-research/<repo>
+3. Read the actual reference implementation code
+4. Read jcode's current implementation
+5. Compare and identify gaps
+
+### Plan Phase
+Write docs/pr-plans/<ID>-<name>.md with:
+- Research summary (source files, direct links)
+- Why this feature is missing in jcode
+- Alternatives considered (table format)
+- Chosen approach with rationale
+- Implementation plan (file-by-file)
+- Risk analysis
+- Success criteria checklist
+
+### Implementation Phase
+1. git checkout -b feat/<ID>-<short-name>
+2. Implement the feature following the plan
+3. cargo build (must pass)
+4. cargo test (must pass)
+5. Update PARITY.md status to ✅
+6. git add + commit
+
+### PR Phase
+1. Create PR with:
+   - Base: master
+   - Title: feat(<area>): <feature name>
+   - Body: Reference the plan file + summary of changes
+   - Labels: feature, <area>
+2. Push branch
+3. Update docs/PR_BACKLOG.md row status to "PR #<number>"
+
+### Cleanup
+- Delete /tmp/feature-research/<repo>/ if you cloned it
+```
+
+### Step 3 — Master Loop
+
+```
+WHILE criteria not met:
+    1. Check PR backlog status
+    2. Identify next unstarted feature from Phase 1-4
+    3. Spawn implementation subagent for that feature
+    4. Wait 5 minutes (or until agent completes)
+    5. IF agent completed:
+       - Verify PR opened
+       - Update backlog
+       - Mark criteria check

+
+## 📊 Progress Tracking
+
+Track in `docs/PR_BACKLOG.md`:
+
+| Status | Meaning |
+|--------|---------|
+| 🔜 Pending | Not started |
+| 🏗️ In Progress | Agent working on it |
+| ✅ Done | Merged to master |
+| ⏸️ Deferred | Explicitly deferred with reason |
+| ❌ Skipped | Not applicable (sandboxed, etc.) |
+| 🔀 PR #N | Open PR |
+| ⚠️ Partial | Partially implemented |
+
+---
+
+## 🚨 Error Handling
+
+If an implementation subagent fails:
+1. Log the error
+2. Restart with same task (max 3 retries)
+3. If 3 retries fail, mark as `deferred` with error summary
+4. Move to next feature
+
+If `cargo build` fails:
+1. Capture error output
+2. Add fix commits to the branch
+3. Retry build
+4. If cannot fix, defer with error summary
+
+If `cargo test` fails:
+1. Run specific failing test with output
+2. Fix test or update test expectations
+3. If test is flaky, add retry logic
+4. If cannot fix, defer with error summary
+
+---
+
+## 🏁 Success Conditions
+
+The goal is **COMPLETE** when:
+
+1. **P0 Complete**: All 6 Phase 1 features (A1-A5, B1) are merged
+2. **P1 Mostly Done**: ≥80% of Phase 2 features are merged or deferred
+3. **Backlog Updated**: Every row in `docs/PR_BACKLOG.md` has a status
+4. **PARITY.md Current**: §XIV accurately reflects implemented vs missing
+
+The goal is **PARTIAL** if:
+- Some features remain unimplemented
+- Report which features remain and why
+
+The goal is **STUCK** if:
+- Agent repeatedly fails on same feature
+- Network/build issues persist
+- Requires human intervention

+## The System: 1 Master + N Subagents
+
+### Master Agent
+
+You are the master agent. Your ONLY responsibilities are:
+
+1. **Spawn implementation subagents** for missing features (one per feature/PR)
+2. **Check every 5 minutes** if subagents are still active
+3. **Evaluate progress** against success criteria
+4. **Restart inactive** subagents (max 3 retries per feature)
+5. **Report status** without stopping until user intervenes
+
+### Implementation Subagent (one per feature)
+
+For each feature, spawn a subagent with this task:
+
+```
+## Task: Implement Feature <ID> - <Name>
+
+### Step 1: Research
+- Check /tmp/feature-research/<source-repo>/ for the reference code
+- Read the actual implementation
+- Read jcode's current implementation in crates/
+- Identify the gap
+
+### Step 2: Plan
+Write docs/pr-plans/<ID>-<name>.md with this structure:
+# PR Plan: <Feature Name>
+
+## Research Summary
+- Source repo(s): <list with URLs to /tmp/feature-research/...>
+- Key files inspected: <paths>
+- Direct code links: <URLs to GitHub>
+
+## Why This Feature Is Missing in jcode

+- [ ] PARITY.md updated
+- [ ] Manual verification works
+
+### Step 3: Implement
+1. git checkout -b feat/<ID>-<short-name>
+2. Make changes per the plan
+3. cargo build (must pass)
+4. cargo test (must pass)
+5. Update PARITY.md to mark feature as ✅
+6. git commit with conventional commit message
+
+### Step 4: PR
+1. Open PR with:
+   - Base: master
+   - Title: feat(<area>): <feature name>
+   - Body: Reference the plan file + summary
+2. Update docs/PR_BACKLOG.md with PR number
+
+### Step 5: Cleanup

+
+---
+
+## Spawning Subagents — Detailed Pattern
+
+For each feature, the master agent should use the Agent tool with:
+
+```python
+Agent(
+    description=f"Implement feature {feature_id}: {feature_name}",
+    prompt=f"""
+You are implementing feature {feature_id} for jcode.
+
+## Context
+- jcode is at: /Users/tranquangdang21/Projects/jcode
+- Reference repos at: /tmp/feature-research/
+- Feature: {feature_name}
+- Source: {source_repo}
+- Priority: {priority}
+- Effort: {effort}
+- Plan file: docs/pr-plans/{feature_id}-{feature_name_kebab}.md
+- Branch: feat/{feature_id}-{feature_name_kebab}
+
+## Your Task
+1. Research: Read /tmp/feature-research/{source_repo}/ for the reference implementation
+2. Plan: Write the plan file at docs/pr-plans/{feature_id}-{feature_name_kebab}.md
+3. Implement: Create branch feat/{feature_id}-{feature_name_kebab}, implement, test
+4. PR: Open PR against master with the plan file referenced
+5. Update: Update docs/PR_BACKLOG.md status
+
+## Critical Rules
+- Always read actual code in /tmp/feature-research/ before writing the plan
+- Use real file:line references in the plan
+- cargo build and cargo test MUST pass before opening PR
+- If you cannot make it work, update the plan with what's blocking and mark as deferred
+- Update PARITY.md in the same PR
+
+Work autonomously. Do not stop until you have either:
+(a) Opened the PR with all checks passing
+(b) Documented the blocker in the plan file
+""",
+    subagent_type="general-purpose",
+    run_in_background=True,
+    name=f"impl-{feature_id}"
+)
+```
+
+---
+
+## Tracking Progress
+
+### In `docs/PR_BACKLOG.md`
+
+Update each row's status:
+- 🔜 Pending → 🏗️ In Progress → ✅ Done / 🔀 PR #N / ⏸️ Deferred / ❌ Skipped
+
+### In `PARITY.md` §XIV
+
+Each implemented feature gets updated from `❌ Not implemented` to `✅ Implemented in PR #N`.
+
+---
+
+## Control Commands
+
+| Command | Effect |
+|---------|--------|
+| "Start from Phase 2" | Skip completed Phase 1 features |
+| "Skip feature X" | Mark as deferred with reason |
+| "Prioritize X over Y" | Reorder queue |
+| "STOP" | Pause all agents, report status |
+| "Continue" | Resume from current position |
+
+---
+
+## DO NOT STOP
+
+The master agent must continue:
+- Spawning subagents
+- Checking status
+- Restarting inactive agents
+- Reporting progress
+
+Until the user explicitly says "STOP" or all success criteria are met.

+# jcode Feature PR Backlog — From 13 Reference Repos
+
+> Goal-driven implementation backlog. Each row = 1 PR against `master`.
+> For each missing feature, the implementation subagent must:
+> 1. Spawn a research subagent to verify the actual code in `/tmp/feature-research/<repo>`
+> 2. Compare against jcode implementation
+> 3. Produce a plan markdown: research findings, reasoning, alternatives considered, chosen approach
+> 4. Implement, test, and open the PR
+> 5. Attach the plan markdown to the PR description
+
+## Priority Legend
+- **P0** — Critical: Blocks core workflows or closes major user-visible gaps
+- **P1** — High: Significant value, matches established patterns in multiple reference repos
+- **P2** — Medium: Nice-to-have, ecosystem parity
+- **P3** — Low: Experimental, niche use cases
+
+## Effort Legend
+- **S** — Small (<1 day)
+- **M** — Medium (1-3 days)

+# PR Plan: Auth Trait andThen + Pipe Combinators
+
+## Research Summary
+- **Source repo(s):** opencode (`/tmp/feature-research/opencode/packages/llm/src/route/auth.ts`)
+- **Key files inspected:** `crates/jcode-llm-core/src/auth.rs` (existing 17,901 bytes, 670 lines, 20+ tests)
+- **Reference code:** opencode `auth.ts` has `andThen`, `orElse`, `pipe` as combinator methods on auth strategies
+
+## Why This Feature Is Missing in jcode
+jcode's Auth trait already has a rich set of 8 types (None, Bearer, ApiKey, Header, Remove, Custom, Optional, Config) and the `or_else` combinator. However, it was missing:
+- **`andThen`** — chain two auths sequentially (both must succeed). Needed for composing header injection + custom validation.
+- **`pipe`** — apply a function to `Box<dyn Auth>` for fluent transformations. Needed for builder-style chaining.
+
+## Alternatives Considered
+
+| Approach | Source Repo | Pros | Cons | Decision |
+|----------|-------------|------|------|----------|
+| Free-standing `and_then()` fn | opencode | Simple, no trait changes | Less discoverable | Chosen: dyn Auth method |
+| `pipe` as method on Auth trait | opencode | Fluent API | Only works with `Box<dyn Auth>` | Chosen: dyn Auth method (matches usage pattern) |
+| Generic `AndThenAuth<S, T>` | N/A | Type-safe | Over-engineered for current needs | Deferred: `Box<dyn Auth>` is sufficient |
+
+## Chosen Approach
+1. **`AndThenAuth`** struct wrapping two `Box<dyn Auth>` — runs first then second, short-circuits on first failure
+2. **`and_then(self: Box<Self>, other: Box<dyn Auth>) -> AndThenAuth`** method on `dyn Auth`
+3. **`pipe(self: Box<Self>, f: impl FnOnce(Box<dyn Auth>) -> A) -> A`** method on `dyn Auth` for fluent transformation
+4. **`pipe_auth()`** free function for ergonomic use without trait import
+
+## Implementation Plan
+- `crates/jcode-llm-core/src/auth.rs`:
+  - Add `AndThenAuth` struct with `Auth` impl
+  - Add `and_then()` and `pipe()` methods on `impl dyn Auth`
+  - Add 5 new tests (both succeed, first fails, second fails, describe, pipe)
+- `crates/jcode-llm-core/src/lib.rs`:
+  - Fix pre-existing stale `test_auth_works()` test that used `Auth::bearer()` and `Request::new()` which no longer exist
+- `crates/jcode-llm-core/src/route.rs`:
+  - Fix pre-existing stale generic-type annotations on `Route<TestBody, TestEvent, TestEvent, TestState>`
+- `crates/jcode-llm-core/src/schema.rs`:
+  - Add `PartialEq, Eq` derive on `ModelRef` for test assertions
+
+## Risk Analysis
+- **Performance:** Negligible — two pointer dereferences for `andThen`
+- **Compatibility:** Fully backward compatible — all existing API unchanged
+- **Security:** No new attack surface
+
+## Success Criteria
+- [x] `cargo check -p jcode-llm-core` passes
+- [x] `cargo test -p jcode-llm-core` — all 61 tests pass
+- [x] `cargo test -p jcode-llm-core --doc` — 0 failed, 1 ignored (intentional)
+- [x] All new tests pass: `test_and_then_both_succeed`, `test_and_then_first_fails`, `test_and_then_second_fails`, `test_and_then_describe`, `test_pipe_transforms_auth_type`
+- [x] PARITY.md updated
