feat(agents): add remaining 15 adapters (droid, amp, agy, crush, aider, goose, auggie, continue, devin, cline, kiro, kilocode, vibe, pi, autohand)

[harshitsinghbhandari]

Summary

Lands the remaining 15 yyovil agent adapters onto main via the cherry-pick recipe from Discussion #148, following #119 (platform) and #145 (grok/cursor/qwen/copilot/kimi).

Adapters added in this PR (registered in registry.Constructors() and activitydispatch.Derivers where applicable):

• droid, amp, agy, crush, aider, goose, auggie, continue, devin, cline, kiro, kilocode, vibe, pi, autohand

After merge, registry.Constructors() will hold the full set of 23 shipped adapters and all 24 entries in migration 0007_allow_implemented_harnesses.sql are wired.

Approach

Per Discussion #148:

cherry-pick the adapter's own commit onto a fresh branch off main … You can batch multiple adapters into one PR (that's what #145 did for the first five).

Commits cherry-picked from origin/agents/02-droid … origin/agents/20-autohand:

Adapter	Cherry-pick
droid	3f94a65
amp	dbb800e
agy	0da8825
crush	8ff7b3a
aider	e37fef8
goose	b936443
auggie	6ffac86
continue	afb9430
devin	0cb96f6
cline	3925e6b
kiro	1e6b496
kilocode	1c58723
vibe	302cab3
pi	2d73665
autohand	8c3e9d9

The first 3 adapters (droid/amp/agy) preserve yyovil's per-adapter commits; the remaining 12 are squashed into one batch commit because each commit's edits to registry.go / activitydispatch/dispatch.go / wiring_test.go conflicted with the previous adapter's additions to the same regions, and resolving each conflict individually was strictly mechanical (keep both sides). The adapter directories themselves are unchanged from yyovil's commits.

Test plan

• cd backend && go build ./... — clean.
• cd backend && go test -race ./... — 1081 passed in 61 packages.
• GitHub CI

Greptile Summary

This PR lands the remaining 15 agent adapters (droid, amp, agy, crush, aider, goose, auggie, continue, devin, cline, kiro, kilocode, vibe, pi, autohand), completing the full set of 23 shipped adapters registered in registry.Constructors() and wiring all 24 entries in the 0007_allow_implemented_harnesses.sql migration.

• Each adapter follows the established pattern: binary resolution with platform-specific PATH fallback, permission-mode mapping, in-command prompt delivery, and where applicable, hook installation or Claude-compat delegation. Tier B adapters (devin, continueagent) reuse claudecode.Plugin.GetAgentHooks to benefit from Claude-format lifecycle hook payloads without duplicating hook-install logic.
• Seven new DeriveActivityState functions are registered in activitydispatch.Derivers; adapters with no native hook surface (Tier C) and those delegating through the claudecode dispatcher are correctly omitted from that map.

Confidence Score: 5/5

All 15 adapters follow the codebase's established patterns, build cleanly, and pass the full test suite including race detection.

The changes are purely additive — new adapter packages wired into the registry and dispatch map with no modifications to existing adapters or shared infrastructure. Each adapter is self-contained and tested. The two new findings are documentation gaps and a code-duplication nit with no effect on runtime behavior.

No files require special attention; the noted issues in agy/agy.go and kilocode/hooks.go are quality-of-life items only.

Important Files Changed

Filename	Overview
backend/internal/adapters/agent/registry/registry.go	Registers all 15 new adapters in Constructors(); ordering matches the PR description and no adapter is duplicated or missing.
backend/internal/adapters/agent/activitydispatch/dispatch.go	Registers 7 new DeriveActivityState functions (droid, agy, goose, cline, kiro, kilocode, autohand); Tier-C and Claude-compat adapters are correctly omitted.
backend/internal/adapters/agent/agy/agy.go	AcceptEdits and Auto permission modes are silently dropped with no explanatory comment, unlike peer adapters that document intentional no-ops.
backend/internal/adapters/agent/kilocode/hooks.go	Duplicates atomicWriteFile locally instead of using hookutil.AtomicWriteFile; sentinel-guarded overwrite/delete logic is correct and idempotent.
backend/internal/adapters/agent/droid/droid.go	Well-structured adapter; permission modes delivered via temp-file settings approach correctly keyed by session id and sanitized for safe path construction.
backend/internal/adapters/agent/continueagent/continueagent.go	Delegates hook install to claudecode.Plugin (Continue's Claude-compat layer), uses --fork for targeted resume rather than --resume (last session only).
backend/internal/adapters/agent/goose/goose.go	Permission delivered via GOOSE_MODE env prefix; Auto and BypassPermissions intentionally collapse to 'auto' (documented); binary name collision with pressly/goose is acknowledged.
backend/internal/adapters/agent/devin/devin.go	Delegates hook install to claudecode.Plugin via Devin's documented Claude-compat layer; AcceptEdits maps to 'auto' with explanatory comment.
backend/internal/daemon/wiring_test.go	Adds resolver coverage for all 15 new adapters including the continue/continueagent name split; complete and consistent.
