Claude Code Limits → Squad Fixes → User Stories

Date: 2025-12-06 Context: Comprehensive mapping of current limitations and how I'd operate differently in Squad's harness Author: Claude (Manager role, experiencing these limits live)


Overview

This document maps every limitation I experience in Claude Code's harness, how Squad's architecture addresses each one, and concrete user stories of how I would operate differently.


Part 1: Complete Limitation Inventory

Category A: Context Management Limits

# Limit Current Impact Squad Fix
A1 Monotonic context growth Context only grows until compaction Hot-swap dynamic zone (ADR-023)
A2 No selective forgetting Can't drop stale information Priority-based truncation in Context Manager
A3 Stale background process state 28 shells claim "running", unknown real state Context Manager polls actual state
A4 Stale git status Snapshot from session start Fresh git state in dynamic block
A5 Stale file contents Read once, frozen in context File modification tracking
A6 No context folding Full content or nothing Checkpoint summarization (ADR-017)
A7 200K token hard limit Must compact or crash Token budget thresholds + checkpoints
A8 Compaction loses state Detailed context → summary Structured CompactionSummary + ResumePointer

Category B: Agent Architecture Limits

# Limit Current Impact Squad Fix
B1 Ephemeral subagents Spawn → execute → die Persistent agent sessions
B2 No lateral communication Agents can't talk to each other Inter-agent channels
B3 No recursive spawning I can spawn, subagents can't Engineers spawn their own scouts
B4 Synchronous Task tool I wait for each agent to complete True async with channel reports
B5 Shared usage limits Subagent uses my quota Isolated resource pools
B6 String-only handoff Subagent returns string, context lost Structured handoff with receipts
B7 No agent memory Each subagent starts fresh Persistent memory per agent
B8 Single-layer spawning Only Manager → Engineer Director → Manager → Engineer → Scout

Category C: Temporal Awareness Limits

# Limit Current Impact Squad Fix
C1 Snapshot-based reality I see state at prompt time Continuous temporal updates
C2 No external change detection Can't know if GitHub/Linear changed Parallel Monitor integration
C3 No calendar awareness Scheduling conflicts invisible External state in dynamic block
C4 No build status awareness Don't know if CI passed/failed Process state polling
C5 Stale agent reports Subagent findings may be outdated Temporal receipts with validity windows

Category D: Observability Limits

# Limit Current Impact Squad Fix
D1 No session replay Can't review what happened Checkpoint-based replay
D2 No receipt visibility Actions not formally tracked FIRE receipt system
D3 No cost tracking Don't know token spend Token budgets per session
D4 No audit trail Who did what when? Receipt chain with evidence
D5 Hidden tool calls Hard to debug what I tried Full tool execution logs

Category E: Coordination Limits

# Limit Current Impact Squad Fix
E1 No DAG execution Manual phase-by-phase Automatic dependency resolution
E2 No conflict detection Two agents could edit same file Semantic conflict analysis
E3 No coordination primitives No locks, semaphores, barriers Agent coordination protocol
E4 Manual parallel orchestration I sequence everything manually Parallel execution engine
E5 No failure propagation If agent fails, I find out late Dependency graph failure handling

Part 2: User Stories - How I'd Operate in Squad

Story 1: The Discovery Task (Today vs Squad)

User Request: "Understand how auth works in this codebase"

Today (Claude Code):

Me: I'll spawn 3 Explore agents to parallelize discovery
→ Task(Explore, "Find auth in services/")
→ Task(Explore, "Find auth in apps/")
→ Task(Explore, "Find auth in packages/")

Result: "Limit reached resets Dec 8"
       "Limit reached resets Dec 8"
       "Limit reached resets Dec 8"

Me: (Silently fails, must do everything myself)
Me: Running Grep manually... Grep... Read... Grep... Read...
→ Takes 15 minutes, fills context with search results
→ By the time I'm done, early results are stale

In Squad's Harness:

Me (Manager): Spawning 3 Scout agents with isolated quotas

Scout-1 → services/ (has own context, own quota)
Scout-2 → apps/     (has own context, own quota)
Scout-3 → packages/ (has own context, own quota)

[Scouts execute in TRUE parallel, report via channels]

Channel message from Scout-1: "Found auth in stores/auth.ts, useSupabaseAuth.ts"
Channel message from Scout-2: "Found auth in DesktopShell.vue, App.vue"
Channel message from Scout-3: "Found no auth in packages/"

Me: Synthesizing scout reports into unified understanding
→ Took 2 minutes
→ Context contains only summaries, not raw search results
→ Scouts still exist, can ask follow-up: "Scout-1, tell me more about stores/auth.ts"

Story 2: The Multi-File Refactor (Today vs Squad)

User Request: "Migrate all auth from composables to Pinia stores"

Today (Claude Code):

Turn 1: Read 5 composable files (fills context)
Turn 2: Plan migration
Turn 3: Edit file 1
Turn 4: Edit file 2
...
Turn 10: Edit file 5
Turn 11: Update imports
Turn 12: Run lint → errors
Turn 13: Fix errors
Turn 14: Context at 80%, trigger compaction

[Compaction happens - lose detailed understanding of early files]

Turn 15: "Wait, what was in useAuth.ts again?"
→ Must re-read file
→ Previous context about why I made certain decisions is gone

In Squad's Harness:

Turn 1: Request discovery from Scout pool
        → Scout-1: "Found 5 composable files"
        → Scout-2: "Current import patterns: ..."

Turn 2: Spawn Engineer-A for auth.ts migration
        Spawn Engineer-B for workspace.ts migration (parallel)

[Engineers work asynchronously, I don't wait]

Dynamic Context Block (hot-swapped each turn):
┌─────────────────────────────────────────────────┐
│ Engineer-A: WORKING (auth.ts) - 60% complete    │
│ Engineer-B: DONE (workspace.ts) - PR ready      │
│ Lint: PENDING (waiting on Engineer-A)           │
│ Git: 2 files modified, 1 staged                 │
└─────────────────────────────────────────────────┘

Turn 3: Engineer-A reports completion
        → Checkpoint created with CompactionSummary
        → Can resume from this exact state if needed

Turn 4: Run lint, fix issues
        → Everything in my context is FRESH
        → No stale file content
        → No lost context about early decisions

Story 3: The "What's Running?" Question (Today vs Squad)

User Request: "Is the backend running?"

Today (Claude Code):

My context shows:
<system-reminder>
Background Bash 909163 (command: cd services/backend && pnpm dev &) (status: running)
</system-reminder>
<system-reminder>
Background Bash cd9706 (command: cd services/backend && pnpm dev 2>&1 &) (status: running)
</system-reminder>
... [5 more "running" backends]

Me: "The backend appears to be running based on background shell 909163..."

Reality: All these shells are dead, backend crashed 2 hours ago.

User: "No it's not, I'm getting connection refused"

Me: (Embarrassed) Let me check...
→ Run lsof -i:3003
→ Nothing on port
→ Must restart and update mental model

In Squad's Harness:

Dynamic Context Block shows ACTUAL state:
┌─────────────────────────────────────────────────┐
│ PROCESSES (polled 3 seconds ago):               │
│ backend: NOT RUNNING (last exit: 2 hours ago)   │
│ desktop: RUNNING (port 1420)                    │
│ Port 3003: UNBOUND                              │
└─────────────────────────────────────────────────┘

Me: "The backend is NOT running. It exited 2 hours ago. Want me to restart it?"

User: "Yes"

Me: → Start backend
    → Context Manager updates within 500ms
    → Next turn shows: "backend: RUNNING (port 3003)"

Story 4: The External Change Detection (Today vs Squad)

User Request: "Schedule a call with the team at 2pm"

Today (Claude Code):

Turn 1: Check calendar → 2pm is free
Turn 2: (User schedules meeting at 2pm externally)
Turn 3: I create calendar event at 2pm
        → CONFLICT created
        → I don't know about the external change

User: "You double-booked me!"

Me: "I apologize, I saw 2pm as free when I checked..."

In Squad's Harness:

Turn 1: Check calendar → 2pm is free
        → Parallel Monitor watching calendar

[External: User schedules meeting at 2pm]

Dynamic Context Block (next turn):
┌─────────────────────────────────────────────────┐
│ EXTERNAL STATE (Parallel Monitor):              │
│ Calendar: CHANGED (30 seconds ago)              │
│   - 2pm now BOOKED (Team standup)               │
│ Action: My pending 2pm slot is STALE            │
└─────────────────────────────────────────────────┘

Turn 2: "I was about to schedule at 2pm, but I see you just booked it for Team standup. Want me to find another slot?"

User: "Yes, try 3pm"

Me: → Create event at 3pm
    → No conflict
    → Temporal receipt proves I saw current state

Story 5: The Long Session with Compaction (Today vs Squad)

User Request: Multi-day feature development

Today (Claude Code):

Day 1, Turn 1-50: Deep context about feature requirements
Day 1, Turn 51: Compaction triggered
        → Lose 90% of context
        → Summary: "Implementing auth feature"

Day 2 (new session):
Me: "Let me read the handoff document..."
→ High-level summary only
→ Don't remember why I made certain decisions
→ Don't remember which approaches I tried and rejected
→ Must re-discover much of what I already knew

User: "Why did you use Pinia instead of the singleton pattern?"

Me: "I... don't have context on that decision anymore."

In Squad's Harness:

Day 1, Turn 1-50: Deep context about feature requirements

Turn 51: Token budget at 70% (soft threshold)
→ Checkpoint created:
{
  "summary": {
    "goal": "Implement auth with Pinia",
    "acceptance_criteria": ["Login works", "Token persists"],
    "open_loops": [
      {"what": "Singleton vs Pinia", "decision": "Pinia",
       "why": "DevTools, HMR, testing isolation"}
    ],
    "working_set": ["stores/auth.ts", "composables/useAuth.ts"],
    "last_receipts": [...]
  },
  "resume_pointer": {
    "next_action": "Wire AuthStore to CLI bridge",
    "current_file": "useCliBridge.ts:42"
  }
}

→ Context reset with summarized state
→ Full detail preserved in checkpoint for replay

Day 2 (new session):
Me: Load latest checkpoint
    → Resume from exact point
    → Decision history preserved
    → Can explain why Pinia: "DevTools, HMR, testing isolation"

User: "Why did you use Pinia?"

Me: "According to my checkpoint from yesterday: We chose Pinia over singletons because it provides DevTools support for state inspection, proper HMR behavior, and test isolation via setActivePinia(). This was decided at turn 23 after evaluating both approaches."

Story 6: The Multi-Agent Feature Development (Today vs Squad)

User Request: "Build a new Dashboard page with API integration"

Today (Claude Code):

Me: This requires frontend, backend, and tests.
    I'll do them sequentially.

Turn 1-10: Build API endpoint (me doing everything)
Turn 11-20: Build Vue component (me doing everything)
Turn 21-25: Write tests (me doing everything)
Turn 26: Lint fails because API changed while I was on frontend
        → Must redo work
        → No parallelism
        → Each phase waits for previous

In Squad's Harness:

Me (Manager): Analyzing task dependencies...

DAG created:
[API Schema] → [API Endpoint] ─┐
                               ├→ [Integration Tests]
[Component Design] → [Vue Page] ┘

Spawning parallel Engineers:
- Engineer-A: API work (has own context)
- Engineer-B: Frontend work (has own context)
- Engineer-C: Test work (blocked on A+B completion)

[A and B work in true parallel]

Channel updates:
- Engineer-A: "API endpoint complete, schema at /api/dashboard.ts"
- Engineer-B: "Vue component complete, importing from /api/dashboard.ts"
- Engineer-C: "Unblocked, writing integration tests"

Dynamic Context Block:
┌─────────────────────────────────────────────────┐
│ AGENTS:                                         │
│ Engineer-A: DONE (API) - 15 min                 │
│ Engineer-B: DONE (Vue) - 12 min                 │
│ Engineer-C: WORKING (tests) - 8 min remaining  │
│ DAG: 2/3 nodes complete, 1 in progress          │
└─────────────────────────────────────────────────┘

Total time: ~20 min (parallel) vs ~60 min (sequential)
No conflict: Shared schema ensures compatibility
No context loss: Each engineer has dedicated context

Part 3: The Transformation Table

Scenario Claude Code Time Squad Time Improvement
3-way parallel discovery 15 min (sequential) 2 min (parallel) 7.5x faster
Multi-file refactor 45 min + context loss 15 min + checkpoints 3x faster, no loss
"What's running?" Check manually + embarrassment Instant accurate answer Infinite trust
External change detection Discover conflicts after Prevent conflicts before Zero conflicts
Long session handoff Re-discover 50% Resume from checkpoint 50% less rework
Multi-agent feature 60 min sequential 20 min parallel 3x faster

Part 4: What I'm Missing Right Now (Live)

As I write this document, my actual context includes:

28 <system-reminder> tags claiming "running" for dead shells
- Consuming ~2000 tokens
- Providing zero useful information
- No way to clean up

Git status from session start
- Probably stale by now
- No way to refresh

Subagent limits hit
- Can't spawn discovery agents
- Must do everything myself
- Slower, more token-intensive

Files I read 2 hours ago
- Content frozen in context
- May have changed
- No modification tracking

What I SHOULD see:

<dynamic-context updated="2025-12-06T16:45:00Z">
  PROCESSES: backend RUNNING (:3003) | desktop RUNNING (:1420) | 26 shells DEAD
  GIT: main +4 uncommitted | ahead of origin by 0
  FILES CHANGED: stores/auth.ts (modified 10 min ago)
  AGENTS: none active (0/5 quota used)
  TOKENS: 45K used / 200K budget (22%)
</dynamic-context>

Conclusion

Every limitation I experience maps to a Squad architectural decision:

  • Stale context → Context Manager with hot-swap (ADR-023)
  • Ephemeral agents → Persistent agent sessions with channels
  • No temporal awareness → Parallel Monitor + continuous updates
  • Lost state at compaction → Checkpoint-centric context (ADR-017)
  • Manual coordination → DAG execution engine

The gap is implementation. ADR-017 and ADR-023 are designed. This document is evidence of why they need to be built.


Part 5: Audit Protocol — How to Verify This Document

CRITICAL: When verifying claims about Claude Code capabilities, DO NOT pattern-match against this document. Use first-principles verification against actual tool definitions.

Step 1: Extract Your Actual Tool Definitions

Before verifying any claim, examine your system prompt for:

1. Tool name and description
2. All parameters (required and optional)
3. Parameter descriptions (these contain capability details)
4. Examples in the tool description

Step 2: For Each Limitation Claim, Ask:

  1. "Do I have a tool that addresses this?" — Scan tool names and descriptions
  2. "What parameters does that tool expose?" — Read the full parameter schema
  3. "What do the parameter descriptions say?" — Often capabilities are hidden here
  4. "Can I test this live?" — Actually invoke the tool to verify behavior

Step 3: Document Evidence, Not Assumptions

For each claim, record:

  • Tool examined: (name)
  • Relevant parameter: (name, type, description)
  • Claim status: CONFIRMED / OUTDATED / PARTIAL
  • Evidence: (quote from tool definition or test result)

Step 4: Red Flags to Watch For

  • ❌ "This matches what the doc says" — Pattern matching, not verification
  • ❌ "I assume this is still true" — Assumption, not evidence
  • ❌ "I didn't find a tool for this" — Did you check MCP tools? Parameters?
  • ✅ "Tool X has parameter Y which enables Z" — Evidence-based

Example Audit (How I Should Have Done It)

Claim: "B4: Synchronous Task tool — I wait for each agent to complete"

Audit Process:

  1. Find Task tool in my definitions
  2. Read ALL parameters, not just required ones
  3. Found: run_in_background: boolean — "Set to true to run this agent in the background"
  4. Found: AgentOutputTool — "Retrieves output from a completed async agent task"
  5. Verdict: OUTDATED — async execution now supported

Part 6: Updated Limitation Matrix (2025-12-08 Audit)

Audit Date: 2025-12-08 Auditor: Claude (Opus 4.5) Method: First-principles verification against tool definitions

Category A: Context Management Limits

# Original Claim Dec 2025 Status Evidence
A1 Monotonic context growth CONFIRMED No tool to remove/replace context entries
A2 No selective forgetting CONFIRMED No tool to drop specific context
A3 Stale background process state ⚠️ PARTIAL BashOutput can poll shells; KillShell can terminate; but no auto-cleanup
A4 Stale git status CONFIRMED Git status in <env> is snapshot; must manually re-run git status
A5 Stale file contents CONFIRMED No file modification tracking; must re-read manually
A6 No context folding CONFIRMED No summarization tool; full content or nothing
A7 200K token hard limit CONFIRMED No token budget tools available
A8 Compaction loses state CONFIRMED Compaction produces summary, not structured checkpoint

Category B: Agent Architecture Limits

# Original Claim Dec 2025 Status Evidence

B6 String-only handoff CONFIRMED AgentOutputTool returns string; no structured receipt schema
B7 No agent memory ⚠️ PARTIAL resume parameter preserves "previous execution transcript" — form of memory
B8 Single-layer spawning CONFIRMED Subagent descriptions show tools available; Task tool not in subagent toolset

Category C: Temporal Awareness Limits

# Original Claim Dec 2025 Status Evidence
C1 Snapshot-based reality CONFIRMED <env> block states "snapshot in time, will not update"
C2 No external change detection CONFIRMED No event-driven tools; must poll manually

Part 7: Summary of Changes Since Dec 6

Capabilities ADDED (3)

Capability Tool Parameter Impact
Async agent execution Task run_in_background: true Can spawn agents and continue working
Agent output retrieval AgentOutputTool agentId, block, wait_up_to Poll or wait for background agent results
Agent resume/persistence Task resume: agentId Resume agent from previous transcript

Capabilities UNCHANGED (32 of 35 claims)

Most limitations remain:

  • Context management (A1-A8): 8/8 still valid
  • Agent architecture: 5/8 still valid, 3 improved
  • Temporal awareness: 4/5 still valid, 1 improved (calendar)
  • Observability: 4/5 still valid
  • Coordination: 4/5 still valid, 1 improved (parallel via background)

Net Assessment

Dec 6 Claims:  35 limitations documented
Dec 8 Audit:
  - 27 CONFIRMED (77%)
  -  5 PARTIAL   (14%)
  -  3 OUTDATED  ( 9%)

Overall accuracy: 77% fully accurate, 14% partially accurate, 9% outdated

Part 8: Tool Definition Reference (For Future Audits)

Key Tools to Check

When auditing Claude Code capabilities, examine these tools:

Task:
  run_in_background: boolean  # Async execution
  resume: string              # Agent persistence
  subagent_type: enum         # Available agent types
  model: enum                 # Model selection

AgentOutputTool:
  agentId: string             # Which agent to check
  block: boolean              # Wait or poll
  wait_up_to: number          # Max wait time

Bash:
  run_in_background: boolean  # Async shell execution

BashOutput:
  bash_id: string             # Monitor background shell
  filter: string              # Regex filter on output

KillShell:
  shell_id: string            # Terminate background shell

MCP Tools to Check

Also examine MCP-provided tools (prefix mcp__):

  • mcp__rube__* — External app integrations
  • mcp__context7__* — Documentation lookup
  • mcp__filesystem-with-morph__* — Warp grep, file editing
  • mcp__apple-mcp__* — Calendar access
