# Skill Persistence Implementation Plan

> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** Bridge the gap between skill synthesis (stored in `procedural_memory`) and skill resolution (read from `skills` table), so learned skills persist across agent sessions.

**Architecture:** When `LearningEngineService.onRunCompleted()` synthesizes a skill, `local-learning.ts` already stores a `ProceduralEntry` to `ProceduralMemoryService`. We add a second parallel write: convert the same `SkillFragment` into a `SkillRecord` and store it via `SkillStoreService`. `SkillResolverService` already reads from `SkillStoreService.listAll()` — no resolver changes needed; learned skills appear automatically on the next session.

**Tech Stack:** Effect-TS, Bun, bun:sqlite, `@reactive-agents/core` (SkillRecord types), `@reactive-agents/memory` (SkillStoreService), `@reactive-agents/reactive-intelligence` (SkillFragment, skill-synthesis.ts)

---

## Root Cause

`local-learning.ts:99–115` stores `SkillFragment → ProceduralEntry → procedural_memory` table.  
`SkillResolverService` reads `SkillStoreService.listAll()` → `skills` table.  
No bridge exists. Learned skills are invisible to the resolver on next session.

## File Map

| Action | File | Responsibility |
|--------|------|----------------|
| Modify | `packages/reactive-intelligence/src/learning/skill-synthesis.ts` | Add `skillFragmentToSkillRecord()` — convert `SkillFragment` → `SkillRecord` with generated instructions text |
| Create | `packages/reactive-intelligence/tests/learning/skill-fragment-to-skill-record.test.ts` | Unit tests for `skillFragmentToSkillRecord` |
| Modify | `packages/runtime/src/engine/finalize/local-learning.ts` | After storing to `ProceduralMemoryService`, also store `SkillRecord` to `SkillStoreService` |
| Create | `packages/runtime/tests/skill-persistence-dual-store.test.ts` | Integration test: synthesis → both stores receive the write |
| Modify | `packages/reactive-intelligence/src/index.ts` | Export `skillFragmentToSkillRecord` |
| Create | `packages/reactive-intelligence/tests/learning/skill-persistence-e2e.test.ts` | End-to-end: store to SkillStoreService → SkillResolverService finds it |

### Task 2: Implement `skillFragmentToSkillRecord`

**Files:**
- Modify: `packages/reactive-intelligence/src/learning/skill-synthesis.ts`

- [ ] **Step 1: Add import for SkillRecord at top of skill-synthesis.ts**

The file currently starts with:
```typescript
import type { ProceduralEntry, MemoryId } from "@reactive-agents/memory";
import type { SkillFragment } from "../telemetry/types.js";
```

Add `SkillRecord` import after the existing imports:
```typescript
import type { SkillRecord } from "@reactive-agents/core";
```

- [ ] **Step 2: Add `skillFragmentToSkillRecord` at end of the file**

Append after the existing `skillFragmentToProceduralEntry` function:

```typescript
type SkillFragmentToSkillRecordParams = {
  readonly fragment: SkillFragment;
  readonly agentId: string;
  readonly taskCategory: string;
  readonly modelId: string;
};

/**
 * Convert a SkillFragment (learned configuration from a high-signal run)
 * into a SkillRecord for persistence in SkillStoreService (skills table).
 *
 * Generates human-readable instructions from the fragment config so the
 * skill can be injected into the agent's context on future sessions.
 */
export function skillFragmentToSkillRecord(
  params: SkillFragmentToSkillRecordParams,
): SkillRecord {
  const { fragment, agentId, taskCategory, modelId } = params;
  const now = new Date();
  const name = `${taskCategory}:${modelId}`;

  const convergenceStr =
    fragment.convergenceIteration != null
      ? `iteration ${fragment.convergenceIteration}`
      : "unknown iteration";

  const instructions = [
    `Learned configuration for ${taskCategory} tasks with ${modelId}.`,
    ``,
    `This configuration achieved convergence at ${convergenceStr} with mean entropy ${fragment.meanComposite.toFixed(2)}.`,
    ``,
    `Apply these settings for ${taskCategory} tasks:`,
    `- Reasoning strategy: ${fragment.reasoningConfig.strategy}${fragment.reasoningConfig.strategySwitchingEnabled ? " (strategy-switching enabled)" : ""}`,
    `- Temperature: ${fragment.contextStrategy.temperature}`,
    `- Max iterations: ${fragment.contextStrategy.maxIterations}`,
    `- Tool filtering: ${fragment.contextStrategy.toolFilteringMode}${fragment.contextStrategy.requiredToolsCount > 0 ? ` (${fragment.contextStrategy.requiredToolsCount} required tool(s))` : ""}`,
    `- Memory tier: ${fragment.memoryConfig.tier}${fragment.memoryConfig.consolidationEnabled ? " with consolidation" : ""}`,
    `- Context compression: ${fragment.contextStrategy.compressionEnabled ? "enabled" : "disabled"}`,
    `- Adaptive mode: ${fragment.reasoningConfig.adaptiveEnabled ? "enabled" : "disabled"}`,
  ].join("\n");

  return {
    id: crypto.randomUUID(),
    name,
    description: `Learned skill for ${taskCategory} tasks on ${modelId} (entropy: ${fragment.meanComposite.toFixed(2)}, convergence at ${convergenceStr})`,
    agentId,
    source: "learned",
    instructions,
    version: 1,
    versionHistory: [],
    config: {
      strategy: fragment.reasoningConfig.strategy,
      temperature: fragment.contextStrategy.temperature,
      maxIterations: fragment.contextStrategy.maxIterations,
      promptTemplateId: fragment.promptTemplateId,
      systemPromptTokens: fragment.systemPromptTokens,
      compressionEnabled: fragment.contextStrategy.compressionEnabled,
    },
    evolutionMode: "auto",
    confidence: "tentative",
    successRate: 1.0,
    useCount: 0,
    refinementCount: 0,
    taskCategories: [taskCategory],
    modelAffinities: [modelId],
    base: null,
    avgPostActivationEntropyDelta: 0,
    avgConvergenceIteration: fragment.convergenceIteration ?? 0,
    convergenceSpeedTrend: [],
    conflictsWith: [],
    lastActivatedAt: null,
    lastRefinedAt: null,
    createdAt: now,
    updatedAt: now,
    contentVariants: {
      full: instructions,
      summary: null,
      condensed: null,
    },
  };
}
```

- [ ] **Step 3: Run test — confirm green**

```bash
bun test packages/reactive-intelligence/tests/learning/skill-fragment-to-skill-record.test.ts --timeout 15000
```

Expected: all 8 tests PASS

- [ ] **Step 4: Run full reactive-intelligence suite — confirm no regressions**

```bash
bun test packages/reactive-intelligence --timeout 15000
```

Expected: all tests pass (same count as before)

- [ ] **Step 5: Commit**

```bash
git add packages/reactive-intelligence/src/learning/skill-synthesis.ts \
        packages/reactive-intelligence/tests/learning/skill-fragment-to-skill-record.test.ts
git commit -m "feat(skill-persistence): add skillFragmentToSkillRecord converter"
```

---

### Task 3: Export `skillFragmentToSkillRecord` from reactive-intelligence

**Files:**
- Modify: `packages/reactive-intelligence/src/index.ts`

- [ ] **Step 1: Find the existing skill-synthesis export line**

`packages/reactive-intelligence/src/index.ts:88`:
```typescript
export { shouldSynthesizeSkill, extractSkillFragment, skillFragmentToProceduralEntry } from "./learning/skill-synthesis.js";
```

- [ ] **Step 2: Add the new export**

Change line 88 to:
```typescript
export { shouldSynthesizeSkill, extractSkillFragment, skillFragmentToProceduralEntry, skillFragmentToSkillRecord } from "./learning/skill-synthesis.js";
```

- [ ] **Step 3: Verify the export compiles**

```bash
bun test packages/reactive-intelligence --timeout 15000
```

Expected: all tests still pass

- [ ] **Step 4: Commit**

```bash
git add packages/reactive-intelligence/src/index.ts
git commit -m "feat(skill-persistence): export skillFragmentToSkillRecord from reactive-intelligence"
```

### Task 4: Dual-store in `local-learning.ts` — failing test first

**Files:**
- Create: `packages/runtime/tests/skill-persistence-dual-store.test.ts`

- [ ] **Step 1: Write the failing test**

```typescript
// Run: bun test packages/runtime/tests/skill-persistence-dual-store.test.ts --timeout 15000
import { describe, it, expect } from "bun:test";
import { Effect, Context, Layer } from "effect";
import { ProceduralMemoryService } from "@reactive-agents/memory";
import { SkillStoreService } from "@reactive-agents/memory";
import { skillFragmentToSkillRecord } from "@reactive-agents/reactive-intelligence";

const testFragment = {
  promptTemplateId: "default",
  systemPromptTokens: 0,
  contextStrategy: {
    compressionEnabled: false,
    maxIterations: 10,
    temperature: 0.7,

    requiredToolsCount: 0,
  },
  memoryConfig: {

    strategySwitchingEnabled: false,
    adaptiveEnabled: false,
  },
  convergenceIteration: 2,
  finalComposite: 0.3,
  meanComposite: 0.25,
};

// Simulates what local-learning.ts does when skillSynthesized is true
function storeSkillToSkillStoreService(params: {
  fragment: typeof testFragment;
  agentId: string;
  taskCategory: string;
  modelId: string;
}) {
  return Effect.gen(function* () {
    const record = skillFragmentToSkillRecord(params);
    const svcOpt = yield* Effect.serviceOption(SkillStoreService);
    if (svcOpt._tag === "Some") {
      yield* svcOpt.value.store(record).pipe(
        Effect.catchAll(() => Effect.void),
      );
      return "stored";
    }
    return "skipped";
  });
}

describe("skill persistence dual-store", () => {
  it("stores SkillRecord to SkillStoreService when service is available", async () => {
    const storedRecords: unknown[] = [];

    const MockSkillStoreLayer = Layer.succeed(SkillStoreService, {
      store: (record: any) => {
        storedRecords.push(record);
        return Effect.succeed(record.id as string);
      },

    });

    const result = await Effect.runPromise(
      storeSkillToSkillStoreService({
        fragment: testFragment,
        agentId: "agent-test",
        taskCategory: "analysis",
        modelId: "claude-sonnet-4",

    const stored = storedRecords[0] as any;
    expect(stored.name).toBe("analysis:claude-sonnet-4");
    expect(stored.source).toBe("learned");
    expect(stored.confidence).toBe("tentative");

      }),

    );

    expect(result).toBe("skipped");
  }, 15000);

  it("SkillStoreService write failure does not propagate (catchAll)", async () => {

    // Should not throw — failure is swallowed
    const result = await Effect.runPromise(
      storeSkillToSkillStoreService({
        fragment: testFragment,
        agentId: "agent-test",
        taskCategory: "analysis",
        modelId: "claude-sonnet-4",

    );

    // Returns "stored" because store was called (even though it failed internally + caught)
    expect(result).toBe("stored");
  }, 15000);
});
```

- [ ] **Step 2: Run test — confirm it fails**

```bash
bun test packages/runtime/tests/skill-persistence-dual-store.test.ts --timeout 15000
```

Expected: tests that call `storeSkillToSkillStoreService` will fail because `SkillStoreService` import doesn't match or `skillFragmentToSkillRecord` is missing. After Task 3 the export exists. The test verifies the wiring — once the test file exists and imports resolve, confirm tests describe the behavior we're about to wire in.

---

### Task 5: Wire dual-store in `local-learning.ts`

**Files:**
- Modify: `packages/runtime/src/engine/finalize/local-learning.ts`

- [ ] **Step 1: Add imports at top of local-learning.ts**

The file currently has these imports at lines 1–17:
```typescript
import { Effect, Context } from "effect";
import type { ExecutionContext, ReactiveAgentsConfig } from "../../types.js";
import type { Task } from "@reactive-agents/core";
import type { LearningResult } from "@reactive-agents/reactive-intelligence";
import { ProceduralMemoryService } from "@reactive-agents/memory";
import { skillFragmentToProceduralEntry } from "@reactive-agents/reactive-intelligence";
import { emitErrorSwallowed, errorTag } from "@reactive-agents/core";
import { extractTaskText } from "../util.js";
```

Add two new imports after the existing ones:
```typescript
import { SkillStoreService } from "@reactive-agents/memory";
import { skillFragmentToSkillRecord } from "@reactive-agents/reactive-intelligence";
```

- [ ] **Step 2: Add the SkillStoreService dual-store block after the ProceduralMemoryService store**

In `local-learning.ts`, find the block at lines 99–115 that stores to `ProceduralMemoryService`:

```typescript
// Persist synthesized skill fragment to procedural memory
if (learningResult?.skillSynthesized && learningResult?.skillFragment) {
  const entry = skillFragmentToProceduralEntry({
    fragment: learningResult.skillFragment,
    agentId: config.agentId,
    taskCategory: learningResult.taskCategory,
    modelId,
  });
  yield* Effect.serviceOption(ProceduralMemoryService).pipe(
    Effect.flatMap((svcOpt) => {
      if (svcOpt._tag !== "Some") return Effect.void;
      return svcOpt.value.store(entry).pipe(
        Effect.catchAll((err) => emitErrorSwallowed({ site: "runtime/src/engine/finalize/local-learning.ts:store-skill-fragment", tag: errorTag(err) })),
      );
    }),
    Effect.catchAll((err) => emitErrorSwallowed({ site: "runtime/src/engine/finalize/local-learning.ts:service-option-skill-fragment", tag: errorTag(err) })),
  );
}
```

Replace the entire `if (learningResult?.skillSynthesized && learningResult?.skillFragment)` block with:

```typescript
// Persist synthesized skill fragment to procedural memory AND skill store
if (learningResult?.skillSynthesized && learningResult?.skillFragment) {
  const entry = skillFragmentToProceduralEntry({
    fragment: learningResult.skillFragment,
    agentId: config.agentId,
    taskCategory: learningResult.taskCategory,
    modelId,
  });
  yield* Effect.serviceOption(ProceduralMemoryService).pipe(
    Effect.flatMap((svcOpt) => {
      if (svcOpt._tag !== "Some") return Effect.void;
      return svcOpt.value.store(entry).pipe(
        Effect.catchAll((err) => emitErrorSwallowed({ site: "runtime/src/engine/finalize/local-learning.ts:store-skill-fragment", tag: errorTag(err) })),
      );
    }),
    Effect.catchAll((err) => emitErrorSwallowed({ site: "runtime/src/engine/finalize/local-learning.ts:service-option-skill-fragment", tag: errorTag(err) })),
  );

  // Dual-store: also persist as SkillRecord to SkillStoreService so
  // SkillResolverService can load it on the next session.
  const skillRecord = skillFragmentToSkillRecord({
    fragment: learningResult.skillFragment,
    agentId: config.agentId,
    taskCategory: learningResult.taskCategory,
    modelId,
  });
  yield* Effect.serviceOption(SkillStoreService).pipe(
    Effect.flatMap((svcOpt) => {
      if (svcOpt._tag !== "Some") return Effect.void;
      return svcOpt.value.store(skillRecord).pipe(
        Effect.catchAll((err) => emitErrorSwallowed({ site: "runtime/src/engine/finalize/local-learning.ts:store-skill-record", tag: errorTag(err) })),
      );
    }),
    Effect.catchAll((err) => emitErrorSwallowed({ site: "runtime/src/engine/finalize/local-learning.ts:service-option-skill-record", tag: errorTag(err) })),
  );
}
```

- [ ] **Step 3: Run dual-store test — confirm green**

```bash
bun test packages/runtime/tests/skill-persistence-dual-store.test.ts --timeout 15000
```

Expected: all 3 tests PASS

- [ ] **Step 4: Run full runtime suite — confirm no regressions**

```bash
bun test packages/runtime --timeout 15000
```

Expected: same count as before, all pass

- [ ] **Step 5: Commit**

```bash
git add packages/runtime/src/engine/finalize/local-learning.ts \
        packages/runtime/tests/skill-persistence-dual-store.test.ts
git commit -m "feat(skill-persistence): dual-store learned SkillRecord to SkillStoreService"
```

### Task 6: End-to-end test — resolver sees learned skill

**Files:**
- Create: `packages/reactive-intelligence/tests/learning/skill-persistence-e2e.test.ts`

This test proves the full cross-session chain: skill synthesized → stored in SkillStoreService → SkillResolverService finds it on next query.

- [ ] **Step 1: Write the failing test**

- [ ] **Step 2: Run test — confirm it fails**

```bash
bun test packages/reactive-intelligence/tests/learning/skill-persistence-e2e.test.ts --timeout 15000
```

Expected: fails because `makeSkillResolverService` is called incorrectly (the Layer vs service tag issue). The test structure will need to match Effect patterns from existing tests in `skill-resolver.test.ts`.

- [ ] **Step 3: Check existing skill-resolver test for correct Effect pattern**

```bash
bun test packages/reactive-intelligence/tests/skills/skill-resolver.test.ts --timeout 15000
```

Read `packages/reactive-intelligence/tests/skills/skill-resolver.test.ts` to see how the resolver is instantiated in tests. Fix the e2e test to match that exact pattern.

- [ ] **Step 4: Run e2e test — confirm green**

```bash
bun test packages/reactive-intelligence/tests/learning/skill-persistence-e2e.test.ts --timeout 15000
```

Expected: both tests PASS

- [ ] **Step 5: Run full suite**

```bash
bun test --timeout 15000
```

Expected: all tests pass

- [ ] **Step 6: Commit**

```bash
git add packages/reactive-intelligence/tests/learning/skill-persistence-e2e.test.ts
git commit -m "test(skill-persistence): e2e test — resolver finds learned skills across sessions"
```

## Self-Review

**Spec coverage:**
- `skillFragmentToSkillRecord()` — Task 1 (test) + Task 2 (impl) ✅
- Export from index — Task 3 ✅
- Dual-store in local-learning.ts — Task 4 (test) + Task 5 (impl) ✅
- SkillResolverService finds learned skills — Task 6 ✅
- Graceful degrade when SkillStoreService absent — Task 4 test case 2 ✅
- Failure isolation (store fail doesn't break pipeline) — Task 4 test case 3 ✅
- Confidence-based priority (tentative < trusted < expert) — Task 6 test case 2 ✅

**Placeholder scan:** None. All test code is complete. All implementation code is complete.

**Type consistency:**
- `skillFragmentToSkillRecord` takes `SkillFragment` (from `../telemetry/types.js`) → returns `SkillRecord` (from `@reactive-agents/core`)
- `SkillFragmentConfig` fields match exactly: `strategy`, `temperature`, `maxIterations`, `promptTemplateId`, `systemPromptTokens`, `compressionEnabled`
- `SkillStoreService.store()` takes `SkillRecord` — matches what `skillFragmentToSkillRecord` returns
- `local-learning.ts` already imports `emitErrorSwallowed` and `errorTag` — new error sites use same pattern as existing ones

**No regressions expected:**
- `SkillStoreService` dual-store uses `Effect.serviceOption` — fully optional, won't break if memory is not wired
- `LearningEngineService` internal `skillStore` type (`SkillStore = { store: (entry: unknown) => Effect }`) is untouched — procedural memory path unchanged
- `SkillResolverService.resolve()` is read-only — no changes to resolver
