Pack comparison
Two packs, side-by-side. Merged comparisons, shared shape, and diff highlights in one view.
session-persistence-three-channels
Append-only JSONL across 3 channels. Permissions never restore on resume — the friction IS the safety.

subagent-delegation-three-isolation-modes
SkillTool vs AgentTool, 6 built-in types, 3 isolation modes. The knob every harness engineer gets wrong first.

Merged comparisons
Head-to-head claims from both packs
Each row is attributed to the pack that authored it. The winner column is normalised to this compare view (A / B / Tie).
| Source | Alternative | Axis | Winner | Note |
|---|---|---|---|---|
| A | claude-code-guide | complexity | Alternative | Claude Code Guide covers session memory in one section; this pack is the dedicated persistence specification with the deliberate-non-feature framing. |
| A | subagent-delegation-three-isolation-modes | maintainability | Tie | This pack documents session + global channels; subagent-delegation documents the sidechain channel. Stack them for full 3-channel coverage. |
| A | injection-surface-audit | accuracy | Tie | The permissions-non-restoration invariant is one of the audit's checks. This pack names the invariant; that pack verifies nothing erodes it. |
| B | advisor-pattern-v2 | cost | Tie | Advisor routes intelligence by confidence (cheap executor + expensive advisor). Subagent delegation routes context (keep wide reads out of the parent window). Different cost axes; stack them when both apply. |
| B | claude-code-guide | complexity | Alternative | Claude Code Guide is a 10-section reference covering the whole harness including subagents. This pack is the deep dive on just subagent delegation — use the guide for onboarding, this pack for production tuning. |
| B | turn-execution-pipeline | latency | Tie | Each subagent runs its own 9-step turn pipeline internally. Subagent spawns add 1-3s round-trip on top of a pipeline turn; fan-out parallelises across children to amortise. |
