Self-review notes

Planning archive — not shipped functionality. This historical proposal is included for developer context. Use the feature guide for supported behavior.

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: One provider-agnostic module (lib/ai) that every AI feature calls, with a platform-level provider config, a per-organization opt-in, a monthly token cap, a usage log, prompt redaction and an untrusted-data wrapper.

Architecture: Pure functions build and parse the two supported wire formats (Anthropic Messages, OpenAI-compatible chat completions). A factory createGateway(deps) holds the policy (configured? org opted in? under budget? timeout, error hygiene, usage record) with every external effect injected, so it is unit-tested without a database or network. lib/ai/index.ts wires the real database, decryptSecret and guardedFetch. The platform configuration page gets a provider card; the organization settings page gets an opt-in switch.

Tech Stack: Next.js server actions, Kysely/Postgres, zod 4, Vitest. No new dependencies.

Spec: AI-FEATURE-IDEAS.txt (F1 AI gateway, F2 guardrails). Build order and shared decisions: docs/superpowers/plans/2026-10-08-ai-00-overview.md.

Global Constraints

No vendor SDK; plain HTTP via lib/guarded-fetch.ts (it blocks private addresses unless allowPrivate).
Provider API key is stored only as encryptSecret() ciphertext and is write-only in the UI (browser learns only "stored").
AI is off until BOTH a platform provider is saved AND the organization Admin opts in.
Provider error bodies are never surfaced or logged (they can echo the prompt or credentials); only HTTP status.
Request timeout 30 seconds. Default completion cap 600 tokens, set per call.
New migration number is 016; migration files are checksummed, never edit a committed one.
Tests import with relative paths (../lib/ai/...) like tests/csv.test.ts.

Review Focus

Provider down, slow, or returning garbage: callers must get a typed error, not a hang or a leaked body (Task 4 tests).
Stored API key silently sent to a new endpoint when an admin edits only the base URL: must require re-entering the key (Task 2 canReuseStoredKey test, Task 6).
Secrets, internal IPs, hostnames and emails reaching a prompt (Task 3 tests).
Cost runaway: monthly cap enforced before any network call; timeout enforced (Task 4 tests).
Organization isolation: an organization that has not opted in never triggers an outbound call (Task 4 test).
OpenAI's newest models may reject max_tokens and require max_completion_tokens. The plan sends max_tokens because Ollama, vLLM and LiteLLM accept it. Verify against the real endpoint at Task 6 Step 7; if it is rejected, change the one field in buildRequest and its test.

Task 1: Migration, schema types, migration constant

Files:

Create: db/migrations/016_ai_gateway.sql
Modify: lib/postgres/schema.ts (PlatformConfigurationTable near line 524, OrganizationTable near line 86, Database interface near line 877)
Modify: lib/migrations.ts:35 (LATEST_MIGRATION_ID, currently stale at 013_... although 014 and 015 exist)

Interfaces:

Produces: columns platform_configuration.ai_provider|ai_base_url|ai_model|ai_api_key_ciphertext|ai_allow_private_endpoint|ai_monthly_token_cap, organizations.ai_enabled, table ai_usage; Kysely names aiProvider, aiBaseUrl, aiModel, aiApiKeyCiphertext, aiAllowPrivateEndpoint, aiMonthlyTokenCap, aiEnabled, aiUsage.
Step 1: Write the migration

db/migrations/016_ai_gateway.sql:

-- Optional AI assistance. Nothing is active until a platform administrator saves
-- a provider and an organization Admin opts in. The API key is encrypted like the
-- other provider secrets in this table (smtp_password_ciphertext).
ALTER TABLE platform_configuration
  ADD COLUMN ai_provider text CHECK (ai_provider IN ('anthropic', 'openai_compatible')),
  ADD COLUMN ai_base_url text,
  ADD COLUMN ai_model text,
  ADD COLUMN ai_api_key_ciphertext text,
  ADD COLUMN ai_allow_private_endpoint boolean NOT NULL DEFAULT false,
  ADD COLUMN ai_monthly_token_cap integer CHECK (ai_monthly_token_cap IS NULL OR ai_monthly_token_cap > 0);

ALTER TABLE organizations
  ADD COLUMN ai_enabled boolean NOT NULL DEFAULT false;

-- One row per provider call. Used for the monthly cap and for acceptance/cost reporting.
CREATE TABLE ai_usage (
  id uuid PRIMARY KEY DEFAULT gen_random_uuid(),
  org_id uuid NOT NULL REFERENCES organizations(id) ON DELETE CASCADE,
  feature text NOT NULL,
  model text NOT NULL,
  input_tokens integer NOT NULL DEFAULT 0,
  output_tokens integer NOT NULL DEFAULT 0,
  latency_ms integer NOT NULL,
  status text NOT NULL CHECK (status IN ('ok', 'error')),
  created_at timestamptz NOT NULL DEFAULT now()
);

CREATE INDEX ai_usage_org_created_idx ON ai_usage (org_id, created_at DESC);

Step 2: Update lib/postgres/schema.ts

Add near the other exported unions (for example above PlatformConfigurationTable):

export type AiProviderId = "anthropic" | "openai_compatible";

Add to PlatformConfigurationTable (after destinationConnectionsCiphertext):

  aiProvider: AiProviderId | null;
  aiBaseUrl: string | null;
  aiModel: string | null;
  /** Encrypted with encryptSecret(); write-only in the UI. */
  aiApiKeyCiphertext: string | null;
  aiAllowPrivateEndpoint: Generated<boolean>;
  aiMonthlyTokenCap: number | null;

Add to OrganizationTable (after statusChangedBy):

  aiEnabled: Generated<boolean>;

Add a new table type after MonitorCheckTable:

export interface AiUsageTable {
  id: Generated<string>;
  orgId: string;
  feature: string;
  model: string;
  inputTokens: Generated<number>;
  outputTokens: Generated<number>;
  latencyMs: number;
  status: "ok" | "error";
  createdAt: GeneratedTimestamp;
}

  aiUsage: AiUsageTable;

Step 3: Bump the migration constant

In lib/migrations.ts change line 35 to:

export const LATEST_MIGRATION_ID = "016_ai_gateway.sql";

Step 4: Typecheck and run existing tests

Run: npx tsc --noEmit && npx vitest run tests/migrations.test.ts Expected: no type errors; migration tests pass (they use their own fake manifest).

Step 5: Apply to the development database and check

Run: npm run db:migrate Expected: output lists 016_ai_gateway.sql as applied. Then run psql "$DATABASE_URL" -c "\d ai_usage" (or any SQL client) and confirm the table and index exist.

Step 6: Commit

git add db/migrations/016_ai_gateway.sql lib/postgres/schema.ts lib/migrations.ts
git commit -m "feat: schema for optional AI assistance (provider config, org opt-in, usage log)"

Task 2: Provider wire formats

Files:

Create: lib/ai/providers.ts
Test: tests/ai-providers.test.ts

Interfaces:

Produces:
- AI_PROVIDERS = ["anthropic", "openai_compatible"] as const, type AiProvider
- type AiEndpointConfig = { provider: AiProvider; baseUrl: string | null; model: string; apiKey: string | null }
- type AiPrompt = { system: string; input: string; maxTokens: number }
- type AiCompletion = { text: string; inputTokens: number; outputTokens: number }
- buildRequest(config: AiEndpointConfig, prompt: AiPrompt): { url: string; headers: Record<string, string>; body: string }
- parseResponse(provider: AiProvider, payload: unknown): AiCompletion (throws on empty or malformed)
- canReuseStoredKey(stored: { provider: string | null; baseUrl: string | null } | undefined, next: { provider: string; baseUrl: string | null }): boolean

Step 2: Run the tests to verify they fail

Run: npx vitest run tests/ai-gateway.test.ts Expected: FAIL, "Failed to resolve import ../lib/ai/gateway".

Step 3: Write the implementation

lib/ai/gateway.ts:

import { buildRequest, parseResponse, type AiEndpointConfig, type AiPrompt } from "@/lib/ai/providers";

export type StoredAiConfig = AiEndpointConfig & { allowPrivate: boolean; monthlyTokenCap: number | null };

}

Step 4: Run the tests to verify they pass

Run: npx vitest run tests/ai-gateway.test.ts Expected: PASS (11 tests).

Step 5: Commit

git add lib/ai/gateway.ts tests/ai-gateway.test.ts
git commit -m "feat: AI gateway policy (opt-in, monthly cap, timeout, error hygiene, usage record)"

Task 5: Real wiring (`lib/ai/index.ts`)

Files:

Create: lib/ai/index.ts

Interfaces:

Consumes: createGateway, StoredAiConfig, AiProviderError, AiUnavailableError from lib/ai/gateway.ts; database, decryptSecret, guardedFetch.
Produces (what every feature imports): complete(call: AiCall): Promise<{ text: string }>, ping(config?: StoredAiConfig), loadAiConfig(): Promise<StoredAiConfig | null>, aiAvailableForOrg(orgId: string): Promise<boolean>, plus re-exports of AiUnavailableError, AiProviderError, StoredAiConfig, AiCall.

This file is thin database and network wiring; the logic it feeds is already covered by Task 4. It is verified by typecheck here and by the manual check in Task 6 Step 7.

Step 1: Write the wiring

lib/ai/index.ts:

import { sql } from "kysely";
import { decryptSecret } from "@/lib/encryption";
import { guardedFetch } from "@/lib/guarded-fetch";
import { database } from "@/lib/postgres/client";
import { createGateway, type StoredAiConfig } from "@/lib/ai/gateway";

export { AiProviderError, AiUnavailableError, type AiCall, type StoredAiConfig } from "@/lib/ai/gateway";

/** The installation's provider, or null when none is saved. No cache: AI calls are rare and this is one indexed row. */
export async function loadAiConfig(): Promise<StoredAiConfig | null> {
  const row = await database
    .selectFrom("platformConfiguration")
    .select(["aiProvider", "aiBaseUrl", "aiModel", "aiApiKeyCiphertext", "aiAllowPrivateEndpoint", "aiMonthlyTokenCap"])
    .where("id", "=", "global")
    .executeTakeFirst();
  if (!row?.aiProvider || !row.aiModel) return null;
  return {
    provider: row.aiProvider,
    baseUrl: row.aiBaseUrl,
    model: row.aiModel,
    apiKey: row.aiApiKeyCiphertext ? decryptSecret(row.aiApiKeyCiphertext) : null,
    allowPrivate: row.aiAllowPrivateEndpoint,
    monthlyTokenCap: row.aiMonthlyTokenCap,
  };
}

async function orgAiEnabled(orgId: string) {
  const row = await database.selectFrom("organizations").select("aiEnabled").where("id", "=", orgId).executeTakeFirst();
  return Boolean(row?.aiEnabled);
}

async function tokensUsedThisMonth(orgId: string) {
  const row = await database
    .selectFrom("aiUsage")
    .select(sql<string>`coalesce(sum(input_tokens + output_tokens), 0)`.as("total"))
    .where("orgId", "=", orgId)
    .where("createdAt", ">=", sql<Date>`date_trunc('month', now())`)
    .executeTakeFirstOrThrow();
  return Number(row.total);
}

const gateway = createGateway({
  loadConfig: loadAiConfig,
  orgEnabled: orgAiEnabled,
  tokensUsedThisMonth,
  recordUsage: async (row) => {
    await database.insertInto("aiUsage").values(row).execute();
  },
  send: (url, init) => guardedFetch(url, init),
});

export const complete = gateway.complete;
export const ping = gateway.ping;

/** True when AI features should be offered to this organization's users. */
export async function aiAvailableForOrg(orgId: string) {
  return Boolean(await loadAiConfig()) && (await orgAiEnabled(orgId));
}

Step 2: Typecheck and lint

Run: npx tsc --noEmit && npx eslint lib/ai tests/ai-*.test.ts --max-warnings=0 Expected: no errors, no warnings.

Step 3: Commit

git add lib/ai/index.ts
git commit -m "feat: wire the AI gateway to the database, encrypted key and guarded fetch"

Task 6: Platform configuration card (provider, key, test, remove)

Files:

Modify: app/platform/(protected)/configuration/actions.ts (add schema + two actions; reuse saveProviders, testOnly, text)
Create: components/platform/AiProviderCard.tsx
Modify: app/platform/(protected)/configuration/page.tsx (mount the card)

Interfaces:

Consumes: canReuseStoredKey, AI_PROVIDERS (providers.ts); ping, StoredAiConfig (lib/ai); existing saveProviders, testOnly, validateHttpTarget, decryptSecret, encryptSecret, INPUT_LIMITS in actions.ts.
Produces: server actions updateAiProvider(formData: FormData): Promise<void | string> (returns a message when intent=test) and removeAiProvider(): Promise<void>; component AiProviderCard({ settings, canManage }).
Step 1: Add imports, schema and actions

At the top of app/platform/(protected)/configuration/actions.ts add:

import { AI_PROVIDERS, canReuseStoredKey } from "@/lib/ai/providers";
import { ping, type StoredAiConfig } from "@/lib/ai";

Below the existing smsProviderSchema add:

const aiProviderSchema = z.object({
  provider: z.enum(AI_PROVIDERS),
  baseUrl: text(INPUT_LIMITS.url),
  model: text(INPUT_LIMITS.name).min(1, "Model is required"),
  apiKey: z.string().trim().max(INPUT_LIMITS.secret),
  allowPrivate: z.boolean(),
  monthlyTokenCap: z
    .string()
    .trim()
    .regex(/^\d*$/, "Enter a whole number of tokens")
    .transform((value) => (value ? Number(value) : null))
    .pipe(z.number().int().positive().max(2_000_000_000).nullable()),
}).refine((input) => input.provider === "anthropic" || input.baseUrl, {
  path: ["baseUrl"],
  message: "A base URL is required for OpenAI-compatible endpoints",
});

At the end of the file add:

/** Saves the AI provider only after a one-word test call succeeds; "Test connection" checks without saving. */
export async function updateAiProvider(formData: FormData) {
  const actor = await requirePlatformCapability("configuration.manage");
  const input = aiProviderSchema.parse({
    provider: formData.get("provider") ?? "anthropic",
    baseUrl: formData.get("baseUrl") ?? "",
    model: formData.get("model") ?? "",
    apiKey: formData.get("apiKey") ?? "",
    allowPrivate: formData.get("allowPrivate") === "on",
    monthlyTokenCap: formData.get("monthlyTokenCap") ?? "",
  });
  const stored = await database
    .selectFrom("platformConfiguration")
    .select(["aiProvider", "aiBaseUrl", "aiApiKeyCiphertext"])
    .where("id", "=", "global")
    .executeTakeFirst();
  const baseUrl = input.baseUrl || null;
  const reusable = canReuseStoredKey(
    stored ? { provider: stored.aiProvider, baseUrl: stored.aiBaseUrl } : undefined,
    { provider: input.provider, baseUrl }
  );
  if (!input.apiKey && stored?.aiApiKeyCiphertext && !reusable) {
    throw new Error("Re-enter the API key when changing the provider or base URL");
  }
  const apiKey = input.apiKey || (reusable && stored?.aiApiKeyCiphertext ? decryptSecret(stored.aiApiKeyCiphertext) : null);
  if (baseUrl) await validateHttpTarget(baseUrl, { allowPrivate: input.allowPrivate });

  const candidate: StoredAiConfig = {
    provider: input.provider,
    baseUrl,
    model: input.model,
    apiKey,
    allowPrivate: input.allowPrivate,
    monthlyTokenCap: input.monthlyTokenCap,
  };
  try {
    await ping(candidate);
  } catch (error) {
    throw new Error(`AI provider check failed: ${error instanceof Error ? error.message : "unknown error"}`);
  }
  if (testOnly(formData)) return `Connected to ${input.model}. Nothing was saved.`;
  await saveProviders(actor, `AI provider set to ${input.provider} / ${input.model}`, "AI_PROVIDER_UPDATED", {
    aiProvider: input.provider,
    aiBaseUrl: baseUrl,
    aiModel: input.model,
    aiApiKeyCiphertext: apiKey ? encryptSecret(apiKey) : null,
    aiAllowPrivateEndpoint: input.allowPrivate,
    aiMonthlyTokenCap: input.monthlyTokenCap,
  }, {
    provider: input.provider,
    baseUrl,
    model: input.model,
    allowPrivate: input.allowPrivate,
    monthlyTokenCap: input.monthlyTokenCap,
    keyChanged: Boolean(input.apiKey),
  });
}

export async function removeAiProvider() {
  const actor = await requirePlatformCapability("configuration.manage");
  await saveProviders(actor, "AI provider removed", "AI_PROVIDER_REMOVED", {
    aiProvider: null,
    aiBaseUrl: null,
    aiModel: null,
    aiApiKeyCiphertext: null,
    aiAllowPrivateEndpoint: false,
    aiMonthlyTokenCap: null,
  }, {});
}

Note: the audit metadata deliberately contains no key material.

Step 2: Create the card

import { Card, CardContent, CardDescription, CardHeader, CardTitle } from "@/components/ui/card";
import { Field } from "@/components/ui/field";
import { IconTile } from "@/components/ui/icon-tile";
import { Input } from "@/components/ui/input";
import { Select } from "@/components/ui/select";
import { StatusBadge } from "@/components/ui/status-badge";

          </PlatformActionForm>
        )}
      </CardContent>
    </Card>
  );
}

Step 3: Mount the card on the configuration page

In app/platform/(protected)/configuration/page.tsx add the import:

import { AiProviderCard } from "@/components/platform/AiProviderCard";

and render it after <DeliveryProvidersCard ... />:

      <AiProviderCard
        canManage={canManage}
        settings={{
          provider: stored?.aiProvider ?? null,
          baseUrl: stored?.aiBaseUrl ?? null,
          model: stored?.aiModel ?? null,
          keyStored: Boolean(stored?.aiApiKeyCiphertext),
          allowPrivate: stored?.aiAllowPrivateEndpoint ?? false,
          monthlyTokenCap: stored?.aiMonthlyTokenCap ?? null,
        }}
      />

Step 4: Typecheck and lint

Run: npx tsc --noEmit && npx eslint "app/platform/(protected)/configuration" components/platform/AiProviderCard.tsx --max-warnings=0 Expected: no errors. If IconTile's props differ from icon={Sparkles}, copy the exact usage from components/platform/DeliveryProvidersCard.tsx (it renders IconTile for each provider section).

Step 5: Run the full unit suite

Run: npm test Expected: all pass (existing 255 plus the new AI tests).

Step 6: Commit

git add "app/platform/(protected)/configuration" components/platform/AiProviderCard.tsx
git commit -m "feat: platform admin card to configure, test and remove the AI provider"

Step 7: Manual check against a real endpoint (required before Plan 2)

Run npm run dev:all, sign in as a platform admin (login-credentials.txt), open Platform > Configuration.

With a real Anthropic key: choose Anthropic, enter a model, paste the key, click Test connection. Expected: "Connected to . Nothing was saved." Then Verify and save; reload; the key field shows "Stored" and the badge says Configured.
Change only the Base URL and click save with the key blank. Expected: error "Re-enter the API key when changing the provider or base URL".
With a local Ollama (ollama serve, ollama pull llama3.1): provider OpenAI-compatible, base URL http://localhost:11434/v1, model llama3.1. Without "Allow a private network endpoint" the test must fail with a private-address message; with it ticked it must succeed.
If an OpenAI endpoint rejects max_tokens, apply the one-field change noted in Review Focus 6 and update tests/ai-providers.test.ts.
Confirm the platform audit log has an AI_PROVIDER_UPDATED entry that contains no key.

Task 7: Organization opt-in switch

Files:

Modify: app/admin/(protected)/settings/actions.ts (add updateOrgAiSettings)
Modify: components/platform/OrganizationSettingsSection.tsx (add a card)

Interfaces:

Consumes: loadAiConfig from lib/ai; requireCapability, writeActiveTenantAudit (already imported in settings/actions.ts); org.aiEnabled from requireSession().
Produces: updateOrgAiSettings(formData: FormData): Promise<void>.
Step 1: Add the action

Append to app/admin/(protected)/settings/actions.ts:

export async function updateOrgAiSettings(formData: FormData) {
  const session = await requireCapability("organization.manage");
  if (session.role !== "ADMIN") throw new Error("Only an organization Admin can change AI assistance");
  const enabled = formData.get("aiEnabled") === "on";
  await writeActiveTenantAudit(session.orgId, {
    actor: session.email,
    action: enabled ? "AI_ASSISTANCE_ENABLED" : "AI_ASSISTANCE_DISABLED",
    target: session.orgId,
  }, async (transaction) => {
    await transaction.updateTable("organizations")
      .set({ aiEnabled: enabled, updatedAt: new Date() })
      .where("id", "=", session.orgId).execute();
  });
  revalidatePath("/organization/platform/orgs");
}

Step 2: Add the card (only when the installation has a provider)

In components/platform/OrganizationSettingsSection.tsx:

Add imports: import { loadAiConfig } from "@/lib/ai";, import { CheckRow } from "@/components/admin/operate-ui";, import { Sparkles } from "lucide-react"; (merge with the existing lucide import) and add updateOrgAiSettings to the existing import from @/app/admin/(protected)/settings/actions.
Add loadAiConfig() to the existing Promise.all and destructure it as aiConfig.
Insert, as a new grid child after the "Data retention" Card:

        {aiConfig && (
          <Card>
            <CardHeader>
              <CardTitle>AI assistance</CardTitle>
              <CardDescription>
                Draft incident updates and explain monitor failures with the model your platform administrator configured
                ({aiConfig.model}). Text you choose to draft from, such as incident notes and component names, is sent to that provider
                with secrets and addresses removed. AI only drafts; you review and publish.

(Sparkles is only needed if you decide to add an IconTile; omit the import otherwise so lint stays clean.)

Step 3: Typecheck, lint, test

Run: npx tsc --noEmit && npx eslint components/platform/OrganizationSettingsSection.tsx "app/admin/(protected)/settings" --max-warnings=0 && npm test Expected: all pass. If org.aiEnabled is missing on the requireSession() org type, confirm requireSession selects the organization with selectAll(); the new column then appears automatically.

Step 4: Manual check

With the Task 6 provider saved, open Platform > Organizations > organization settings. Expected: an "AI assistance" card. Toggle on and save; the tenant audit log gets AI_ASSISTANCE_ENABLED. With the provider removed, the card disappears.

Step 5: Final verification and commit

Run: npm run verify Expected: lint (zero warnings), typecheck, tests, and build all succeed.

git add "app/admin/(protected)/settings/actions.ts" components/platform/OrganizationSettingsSection.tsx
git commit -m "feat: organization Admins opt in to AI assistance"

Self-review notes

Spec coverage: F1 provider-agnostic, BYO local model (Tasks 2, 5, 6), per-org on/off (7), budgets (4), kill switch (remove provider, 6), usage log (1, 5), encrypted key (6), SSRF-safe transport with private-endpoint opt-in (5, 6), tests with a fake provider (4). F2 redaction (3), untrusted wrapper (3), draft-first rule (enforced by features in Plans 2-3, none publish), audit of config changes (6, 7). Not built, by design: per-organization keys, JSON-schema enforcement helper (no feature needs it yet), per-feature switches (add when a second feature needs independent control).
Types are consistent across tasks: StoredAiConfig, UsageRow, SendInit, AiCall, AiProvider.

AI Gateway Implementation Plan

Global Constraints

Review Focus

Task 1: Migration, schema types, migration constant

Task 2: Provider wire formats

Task 3: Redaction and untrusted-data wrapper

Task 4: Gateway policy (createGateway)

Task 5: Real wiring (lib/ai/index.ts)

Task 6: Platform configuration card (provider, key, test, remove)

Task 7: Organization opt-in switch

Self-review notes

Task 4: Gateway policy (`createGateway`)

Task 5: Real wiring (`lib/ai/index.ts`)
