feat: live stack-state injection via agent harness hook (#304) by aarontrowbridge · Pull Request #306 · harmoniqs/amicode

aarontrowbridge · 2026-08-09T02:25:01Z

Implements #304.

Adds a second opencode plugin (amicode_context.ts) implementing experimental.chat.system.transform that reads live state on every prompt build and injects it as the final system[] entry.

Scope (expanded 2026-08-21): the original WIP moved solver mode + routing off the boot-time file splice. This update finishes the job — the fleet line and the user-memory sections (profile, recent problems, reference demos, mount stack, memory index) also move to the live hook. Motivation: the boot-time splices were the "Amicode forgets the fleet" bug class — a hand-maintained server bundle (the canonical launchd server's staging dir) or a stale re-prep served yesterday's memory index and yesterday's solver mode to every new session (observed: 10-entry index frozen at Aug 16 vs 18 live; cloud-HP solver instructions served after the user switched back to Piccolo).

Key changes:

opencode-plugin/stack_state.ts — standalone state readers + markdown builders (node-builtins only for Bun runtime): solver mode, routing, active problem, live runs (original WIP) + NEW lean fleet line (~/.amico/ops/fleet/fleet.json role, fleet-status.json devices/freshness with stale/unreadable degradation, on-demand pointers — absent fleet.json renders nothing) + NEW marker-only Armonia mount discovery (smol-toml-free port of mount_store semantics: kind ranks, duplicate-id skip, kind-rank ordering) and the five user-memory sections read live from the personal vault, section text byte-identical to the retired substrate/user_splice.ts builders. No mounts.toml manifest support (smol-toml unavailable in Bun; no manifest exists in practice — documented in-module).
opencode-plugin/amicode_context.ts — the plugin, single export, one hook (unchanged)
src/opencode_config.ts — solver/routing AND the user-memory/mount/memory-index splices removed from prepareOpencodeProject (the latter previously the only injector); buildOpencodeConfigContent accepts extraPluginPaths (original WIP)
src/extension.ts — boot + solver-switch register the context plugin; solver-switch projectDir asymmetry fixed (original WIP)
packages/extension/AGENTS.md — single broadened recovery pointer (template tail) covering solver mode, routing, fleet, and the vault files; replaces the WIP's programmatic append (was duplicated)
Deletedsubstrate/user_splice.ts + the now-dead vault_store index readers (KNOWLEDGE/DEMOS/MEMORY) — the plugin owns that text now, pinned golden in test/stack_state.test.ts (14 cases: fleet rendering + degradation, mount discovery incl. duplicate/marker-less skips, section text parity with the retired builders, caps 50/30/50, splice-parity section order, hermetic env-seam composition). solverModeSection/routingSection deliberately stay as the original WIP's parity oracles (test-only) — noted asymmetry, reviewer's call whether to fold them into stack_state pins too.
test/packaging.test.ts — pins amicode_context.ts + stack_state.ts as must-ship vsix assets.

Hook support verified against the deployed fork binary: experimental.chat.system.transform is typed (packages/plugin/src/index.ts:291), triggered (agent/agent.ts:381), and the frozen canonical server binary contains the hook string. Silent no-op remains the failure mode if a binary lacks it — which is why the recovery pointer exists.

Deployment sequencing (the canonical launchd server serves a hand-staged bundle):

Merge + release a vsix carrying the plugin files (the server config's existing amicode_context.ts reference — dead since it was added — goes live the moment the newest installed vsix ships it).
Restart the canonical server (it resolves __EXT__ to the newest vsix at boot).
Strip the now-duplicated static sections (About this user / recent problems / reference demos / mount stack / memory index) from the staged ~/.amico/server/opencode-project-staging/opencode-project/AGENTS.md — until then they render twice (harmless, just noisy).

Verification: tsc --noEmit clean; full extension suite 1186 passed / 5 skipped / 100 files.

Summary by CodeRabbit

New Features
- Added live context injection for solver status, routing, fleet information, active work, profile data, and relevant memory.

📝 Walkthrough

Walkthrough

The extension now injects live solver, fleet, problem, routing, and personal-vault context into OpenCode prompts. Startup no longer splices this data into AGENTS.md. New stack-state readers, plugin wiring, packaging checks, and tests support the change.

Changes

Live context injection

Layer / File(s)	Summary
Stack-state collection and rendering `packages/extension/opencode-plugin/stack_state.ts`, `packages/extension/test/stack_state.test.ts`	The new builder reads operational state and vault data, discovers mounts, renders ordered markdown sections, applies content caps, and handles missing or malformed files.
OpenCode plugin wiring `packages/extension/opencode-plugin/amicode_context.ts`, `packages/extension/src/opencode_config.ts`, `packages/extension/src/extension.ts`, `packages/extension/AGENTS.md`, `packages/extension/test/packaging.test.ts`	The plugin appends live context during system-prompt transformation. Initial and restart configurations register the plugin, and packaged assets include its runtime files.
Startup splice removal and migration coverage `packages/extension/src/substrate/vault_store.ts`, `packages/extension/src/opencode_config.ts`, `packages/extension/test/scores/prep_integration.test.ts`	Startup writes only compiled `AGENTS.md` content. Obsolete user-memory readers and splice helpers are removed. Integration tests verify live injection and recovery-pointer behavior.

Adds a second opencode plugin (amicode_context.ts) implementing experimental.chat.system.transform that reads solver mode, routing, active problem, and live runs on every prompt build and injects them as the final system[] entry. - opencode-plugin/stack_state.ts — standalone state readers + builders - opencode-plugin/amicode_context.ts — system.transform hook plugin - src/opencode_config — removed solver/routing from file splice; buildOpencodeConfigContent accepts extraPluginPaths param - src/extension.ts — registers context plugin in boot + solver-switch; fixes mkdtemp asymmetry in solver-switch re-prep - AGENTS.md — one-line recovery pointer appended Closes#304.

Extends the amicode_context plugin's system.transform injection so the sections that went stale as boot-time file splices are read LIVE from disk on every prompt build: - stack_state.ts: lean fleet line (role from fleet.json, devices + freshness from fleet-status.json, on-demand pointers) — absent fleet.json renders nothing; marker-only Armonia mount discovery (smol-toml-free port of mount_store semantics: kind ranks, duplicate skip, kind-rank order) + the user-memory sections (profile, recent problems, reference demos, mount stack, memory index) read from the personal vault, section text byte-identical to the retired substrate/user_splice.ts builders (pinned golden in test/stack_state.test.ts, 14 cases incl. caps + splice-parity order) - opencode_config.ts: the boot-time user-memory/mount/memory splices are REMOVED (they were the staleness bug: hand-maintained server bundles and re-prepped project dirs served yesterday's memory index); the template AGENTS.md carries the single broadened recovery pointer (replaces the programmatic append — was duplicated) - user_splice.ts + vault_store's now-dead index readers deleted; solverModeSection/routingSection stay as the WIP's parity oracles - packaging.test.ts pins amicode_context.ts + stack_state.ts as must-ship vsix assets (the server config's dead reference goes live the moment a vsix carries them) Closes the 'Amicode forgets the fleet' class: a distiller write, a solver switch, or a vault sync reaches the next message without a re-prep or server restart.

Adds a second opencode plugin (amicode_context.ts) implementing experimental.chat.system.transform that reads solver mode, routing, active problem, and live runs on every prompt build and injects them as the final system[] entry. - opencode-plugin/stack_state.ts — standalone state readers + builders - opencode-plugin/amicode_context.ts — system.transform hook plugin - src/opencode_config — removed solver/routing from file splice; buildOpencodeConfigContent accepts extraPluginPaths param - src/extension.ts — registers context plugin in boot + solver-switch; fixes mkdtemp asymmetry in solver-switch re-prep - AGENTS.md — one-line recovery pointer appended Closes#304.

Extends the amicode_context plugin's system.transform injection so the sections that went stale as boot-time file splices are read LIVE from disk on every prompt build: - stack_state.ts: lean fleet line (role from fleet.json, devices + freshness from fleet-status.json, on-demand pointers) — absent fleet.json renders nothing; marker-only Armonia mount discovery (smol-toml-free port of mount_store semantics: kind ranks, duplicate skip, kind-rank order) + the user-memory sections (profile, recent problems, reference demos, mount stack, memory index) read from the personal vault, section text byte-identical to the retired substrate/user_splice.ts builders (pinned golden in test/stack_state.test.ts, 14 cases incl. caps + splice-parity order) - opencode_config.ts: the boot-time user-memory/mount/memory splices are REMOVED (they were the staleness bug: hand-maintained server bundles and re-prepped project dirs served yesterday's memory index); the template AGENTS.md carries the single broadened recovery pointer (replaces the programmatic append — was duplicated) - user_splice.ts + vault_store's now-dead index readers deleted; solverModeSection/routingSection stay as the WIP's parity oracles - packaging.test.ts pins amicode_context.ts + stack_state.ts as must-ship vsix assets (the server config's dead reference goes live the moment a vsix carries them) Closes the 'Amicode forgets the fleet' class: a distiller write, a solver switch, or a vault sync reaches the next message without a re-prep or server restart.

Implements #304.

Adds a second opencode plugin (amicode_context.ts) implementing experimental.chat.system.transform that reads live state on every prompt build and injects it as the final system[] entry.

Scope (expanded 2026-08-21): the original WIP moved solver mode + routing off the boot-time file splice. This update finishes the job — the fleet line and the user-memory sections (profile, recent problems, reference demos, mount stack, memory index) also move to the live hook. Motivation: the boot-time splices were the "Amicode forgets the fleet" bug class — a hand-maintained server bundle (the canonical launchd server's staging dir) or a stale re-prep served yesterday's memory index and yesterday's solver mode to every new session (observed: 10-entry index frozen at Aug 16 vs 18 live; cloud-HP solver instructions served after the user switched back to Piccolo).

Key changes:

opencode-plugin/stack_state.ts — standalone state readers + markdown builders (node-builtins only for Bun runtime): solver mode, routing, active problem, live runs (original WIP) + NEW lean fleet line (~/.amico/ops/fleet/fleet.json role, fleet-status.json devices/freshness with stale/unreadable degradation, on-demand pointers — absent fleet.json renders nothing) + NEW marker-only Armonia mount discovery (smol-toml-free port of mount_store semantics: kind ranks, duplicate-id skip, kind-rank ordering) and the five user-memory sections read live from the personal vault, section text byte-identical to the retired substrate/user_splice.ts builders. No mounts.toml manifest support (smol-toml unavailable in Bun; no manifest exists in practice — documented in-module).
opencode-plugin/amicode_context.ts — the plugin, single export, one hook (unchanged)
src/opencode_config.ts — solver/routing AND the user-memory/mount/memory-index splices removed from prepareOpencodeProject (the latter previously the only injector); buildOpencodeConfigContent accepts extraPluginPaths (original WIP)
src/extension.ts — boot + solver-switch register the context plugin; solver-switch projectDir asymmetry fixed (original WIP)
packages/extension/AGENTS.md — single broadened recovery pointer (template tail) covering solver mode, routing, fleet, and the vault files; replaces the WIP's programmatic append (was duplicated)
Deletedsubstrate/user_splice.ts + the now-dead vault_store index readers (KNOWLEDGE/DEMOS/MEMORY) — the plugin owns that text now, pinned golden in test/stack_state.test.ts (14 cases: fleet rendering + degradation, mount discovery incl. duplicate/marker-less skips, section text parity with the retired builders, caps 50/30/50, splice-parity section order, hermetic env-seam composition). solverModeSection/routingSection deliberately stay as the original WIP's parity oracles (test-only) — noted asymmetry, reviewer's call whether to fold them into stack_state pins too.
test/packaging.test.ts — pins amicode_context.ts + stack_state.ts as must-ship vsix assets.

Hook support verified against the deployed fork binary: experimental.chat.system.transform is typed (packages/plugin/src/index.ts:291), triggered (agent/agent.ts:381), and the frozen canonical server binary contains the hook string. Silent no-op remains the failure mode if a binary lacks it — which is why the recovery pointer exists.

Deployment sequencing (the canonical launchd server serves a hand-staged bundle):

Merge + release a vsix carrying the plugin files (the server config's existing amicode_context.ts reference — dead since it was added — goes live the moment the newest installed vsix ships it).
Restart the canonical server (it resolves __EXT__ to the newest vsix at boot).
Strip the now-duplicated static sections (About this user / recent problems / reference demos / mount stack / memory index) from the staged ~/.amico/server/opencode-project-staging/opencode-project/AGENTS.md — until then they render twice (harmless, just noisy).

Verification: tsc --noEmit clean; full extension suite 1186 passed / 5 skipped / 100 files.

Summary by CodeRabbit

Walkthrough

The extension now injects live solver, fleet, problem, routing, and personal-vault context into OpenCode prompts. Startup no longer splices this data into AGENTS.md. New stack-state readers, plugin wiring, packaging checks, and tests support the change.

Changes

Live context injection

Layer / File(s)	Summary
Stack-state collection and rendering `packages/extension/opencode-plugin/stack_state.ts`, `packages/extension/test/stack_state.test.ts`	The new builder reads operational state and vault data, discovers mounts, renders ordered markdown sections, applies content caps, and handles missing or malformed files.
OpenCode plugin wiring `packages/extension/opencode-plugin/amicode_context.ts`, `packages/extension/src/opencode_config.ts`, `packages/extension/src/extension.ts`, `packages/extension/AGENTS.md`, `packages/extension/test/packaging.test.ts`	The plugin appends live context during system-prompt transformation. Initial and restart configurations register the plugin, and packaged assets include its runtime files.
Startup splice removal and migration coverage `packages/extension/src/substrate/vault_store.ts`, `packages/extension/src/opencode_config.ts`, `packages/extension/test/scores/prep_integration.test.ts`	Startup writes only compiled `AGENTS.md` content. Obsolete user-memory readers and splice helpers are removed. Integration tests verify live injection and recovery-pointer behavior.

Adds a second opencode plugin (amicode_context.ts) implementing experimental.chat.system.transform that reads solver mode, routing, active problem, and live runs on every prompt build and injects them as the final system[] entry. - opencode-plugin/stack_state.ts — standalone state readers + builders - opencode-plugin/amicode_context.ts — system.transform hook plugin - src/opencode_config — removed solver/routing from file splice; buildOpencodeConfigContent accepts extraPluginPaths param - src/extension.ts — registers context plugin in boot + solver-switch; fixes mkdtemp asymmetry in solver-switch re-prep - AGENTS.md — one-line recovery pointer appended Closes#304.

Extends the amicode_context plugin's system.transform injection so the sections that went stale as boot-time file splices are read LIVE from disk on every prompt build: - stack_state.ts: lean fleet line (role from fleet.json, devices + freshness from fleet-status.json, on-demand pointers) — absent fleet.json renders nothing; marker-only Armonia mount discovery (smol-toml-free port of mount_store semantics: kind ranks, duplicate skip, kind-rank order) + the user-memory sections (profile, recent problems, reference demos, mount stack, memory index) read from the personal vault, section text byte-identical to the retired substrate/user_splice.ts builders (pinned golden in test/stack_state.test.ts, 14 cases incl. caps + splice-parity order) - opencode_config.ts: the boot-time user-memory/mount/memory splices are REMOVED (they were the staleness bug: hand-maintained server bundles and re-prepped project dirs served yesterday's memory index); the template AGENTS.md carries the single broadened recovery pointer (replaces the programmatic append — was duplicated) - user_splice.ts + vault_store's now-dead index readers deleted; solverModeSection/routingSection stay as the WIP's parity oracles - packaging.test.ts pins amicode_context.ts + stack_state.ts as must-ship vsix assets (the server config's dead reference goes live the moment a vsix carries them) Closes the 'Amicode forgets the fleet' class: a distiller write, a solver switch, or a vault sync reaches the next message without a re-prep or server restart.

Implements #304.

Adds a second opencode plugin (amicode_context.ts) implementing experimental.chat.system.transform that reads live state on every prompt build and injects it as the final system[] entry.

Scope (expanded 2026-08-21): the original WIP moved solver mode + routing off the boot-time file splice. This update finishes the job — the fleet line and the user-memory sections (profile, recent problems, reference demos, mount stack, memory index) also move to the live hook. Motivation: the boot-time splices were the "Amicode forgets the fleet" bug class — a hand-maintained server bundle (the canonical launchd server's staging dir) or a stale re-prep served yesterday's memory index and yesterday's solver mode to every new session (observed: 10-entry index frozen at Aug 16 vs 18 live; cloud-HP solver instructions served after the user switched back to Piccolo).

Key changes:

opencode-plugin/stack_state.ts — standalone state readers + markdown builders (node-builtins only for Bun runtime): solver mode, routing, active problem, live runs (original WIP) + NEW lean fleet line (~/.amico/ops/fleet/fleet.json role, fleet-status.json devices/freshness with stale/unreadable degradation, on-demand pointers — absent fleet.json renders nothing) + NEW marker-only Armonia mount discovery (smol-toml-free port of mount_store semantics: kind ranks, duplicate-id skip, kind-rank ordering) and the five user-memory sections read live from the personal vault, section text byte-identical to the retired substrate/user_splice.ts builders. No mounts.toml manifest support (smol-toml unavailable in Bun; no manifest exists in practice — documented in-module).
opencode-plugin/amicode_context.ts — the plugin, single export, one hook (unchanged)
src/opencode_config.ts — solver/routing AND the user-memory/mount/memory-index splices removed from prepareOpencodeProject (the latter previously the only injector); buildOpencodeConfigContent accepts extraPluginPaths (original WIP)
src/extension.ts — boot + solver-switch register the context plugin; solver-switch projectDir asymmetry fixed (original WIP)
packages/extension/AGENTS.md — single broadened recovery pointer (template tail) covering solver mode, routing, fleet, and the vault files; replaces the WIP's programmatic append (was duplicated)
Deletedsubstrate/user_splice.ts + the now-dead vault_store index readers (KNOWLEDGE/DEMOS/MEMORY) — the plugin owns that text now, pinned golden in test/stack_state.test.ts (14 cases: fleet rendering + degradation, mount discovery incl. duplicate/marker-less skips, section text parity with the retired builders, caps 50/30/50, splice-parity section order, hermetic env-seam composition). solverModeSection/routingSection deliberately stay as the original WIP's parity oracles (test-only) — noted asymmetry, reviewer's call whether to fold them into stack_state pins too.
test/packaging.test.ts — pins amicode_context.ts + stack_state.ts as must-ship vsix assets.

Hook support verified against the deployed fork binary: experimental.chat.system.transform is typed (packages/plugin/src/index.ts:291), triggered (agent/agent.ts:381), and the frozen canonical server binary contains the hook string. Silent no-op remains the failure mode if a binary lacks it — which is why the recovery pointer exists.

Deployment sequencing (the canonical launchd server serves a hand-staged bundle):

Merge + release a vsix carrying the plugin files (the server config's existing amicode_context.ts reference — dead since it was added — goes live the moment the newest installed vsix ships it).
Restart the canonical server (it resolves __EXT__ to the newest vsix at boot).
Strip the now-duplicated static sections (About this user / recent problems / reference demos / mount stack / memory index) from the staged ~/.amico/server/opencode-project-staging/opencode-project/AGENTS.md — until then they render twice (harmless, just noisy).

Verification: tsc --noEmit clean; full extension suite 1186 passed / 5 skipped / 100 files.

Summary by CodeRabbit
