Here is what is almost certainly happening and how to fix it. + +## The root cause + +You are pointing `prisma db pull` (introspection) at Neon's **pooled** connection string — the one with `-pooler` in the hostname. That endpoint runs PgBouncer in **transaction mode**, which breaks the prepared statements that Prisma's migration/introspection engine relies on. The query engine hangs waiting on a statement that never resolves cleanly, and you hit the ~30s timeout. + +The reason `psql` "works fine" against the same URL is that `psql` doesn't use prepared statements the way Prisma's query engine does, so transaction-mode pooling doesn't trip it up. That's the trap — the URL is valid, it just isn't the right URL for this command. + +## The fix: split into two URLs + +In your `schema.prisma`: + +```prisma +datasource db { + provider = "postgresql" + url = env("DATABASE_URL") // pooled (-pooler), used by Prisma Client at runtime + directUrl = env("DIRECT_URL") // DIRECT (non-pooled), used by db pull / migrate / db push +} +``` + +- `DATABASE_URL` -> the **pooled** string (host contains `-pooler`), keep `?pgbouncer=true&connection_limit=1` for serverless/runtime use. +- `DIRECT_URL` -> the **direct** string from the Neon console (same creds, host does **not** contain `-pooler`). This is what `db pull`, `prisma migrate dev`, and `prisma db push` must use. + +In the Neon Console -> Connect dialog, both strings are shown side by side ("Pooled connection" and "Direct connection"). Copy them into separate env vars. + +Optionally bump the connect timeout on the direct URL to absorb Neon cold starts (Neon suspends idle compute after ~5 min, so the first connection after idle can take several seconds): + +```dotenv +DIRECT_URL="postgresql://user:pass@ep-xxx.us-east-2.aws.neon.tech/db?sslmode=require&connect_timeout=30" +``` + +## pnpm monorepo gotchas (these bite too) + +1. **Run Prisma scoped to the package that owns the schema.** From the repo root: + + ```bash + pnpm --filter @your-scope/db exec prisma db pull + ``` + + Running bare `prisma db pull` at the root resolves `schema.prisma` and `.env` from the wrong directory and silently picks up the wrong/missing env. + +2. **`.env` loading location.** Prisma auto-loads `.env` from the directory of `schema.prisma`, not necessarily the repo root. Put a `.env` (with both `DATABASE_URL` and `DIRECT_URL`) next to `schema.prisma` in that package, or load env explicitly. If you use a root `.env`, confirm your tool (e.g. `dotenv-cli`, Turbo `dependsOn: ["^db:generate"]`) actually injects `DIRECT_URL` — a missing `directUrl` env var causes Prisma to fall back to the pooled `url`, reintroducing the hang. + +3. **The `prisma` binary resolution.** In pnpm workspaces, use the locally-installed `prisma` via `pnpm exec prisma` or an npm script in the package. A globally-installed `prisma` can resolve the wrong `schema.prisma`. + +## Quick verification order + +1. Confirm the string you're giving `db pull` has **no `-pooler`** in the host (or is wired via `directUrl`). +2. `echo $DIRECT_URL` from the package dir to confirm it's actually set in that shell. +3. Run `pnpm --filter exec prisma db pull` (not bare `prisma`). +4. If it still times out, append `&connect_timeout=60` and retry — if that fixes it, it was a cold-start race, not the pooling issue. + +## TL;DR + +`db pull` against a Neon **pooled** URL hangs because PgBouncer transaction mode breaks Prisma's introspection statements.

Check your `moduleResolution` first (this is the #1 cause) + +`paths` only behaves correctly under certain resolution modes: + +- `moduleResolution: "node"` (a.k.a. `"node10"`) — the classic. Resolves `exports` **only partially** and needs `paths` for workspace packages. Most legacy setups use this. +- `moduleResolution: "node16"` / `"nodenext"` — respects `exports`/`condition` keys (`types`, `import`, `require`, `default`) strictly. If your package's `exports` doesn't declare a `"types"` condition, TS2307 happens. +- `moduleResolution: "bundler"` — the modern default for app/bundler code. Reads `exports` like nodenext but is more forgiving; great for monorepos where you ship `.ts` source. + +If you've set `paths` but still get TS2307, the resolution mode is fighting you.

Make the workspace package resolvable via `exports` + `workspace:*` dep, not `paths` + +The cleanest pattern (and the one that avoids `paths` entirely) is: + +**In the importing package's `package.json`**, declare the real dependency: + +```jsonc +{ + "dependencies": { + "@yourscope/db": "workspace:*", + }, +} +``` + +Then **run `pnpm install`** so pnpm creates the symlink in `node_modules/@yourscope/db -> ../../packages/db`. + +**In the target package's `package.json`**, point `exports` at the actual source files: + +```jsonc +{ + "name": "@yourscope/db", + "type": "module", + "exports": { + ".": { "default": "./src/index.ts" }, + "./*": { "default": "./src/*.ts" }, + }, +} +``` + +With `moduleResolution: "bundler"` (or `nodenext`), TypeScript resolves `@yourscope/db` through the `node_modules` symlink, reads `exports`, and lands directly on `src/index.ts`. **No `paths` entry needed.** This is why your import works at runtime (the bundler/node does the same thing) and why it _should_ work in `tsc` once resolution mode is right. + +## 3. If you must use `paths`, the glob must match the import _exactly_ + +Two sub-cases — they are NOT interchangeable: + +**(a) Importing the package root** (`import { x } from "@yourscope/db"`): + +```jsonc +"paths": { + "@yourscope/db": ["./packages/db/src/index.ts"], + "@yourscope/db/*": ["./packages/db/src/*"] +} +``` + +You need both lines. The bare `@yourscope/db` entry handles the root import; `/*` handles subpath imports. + +**(b) `paths` does not create the package — `baseUrl` matters.** With `moduleResolution: "node"`, `paths` is resolved relative to `baseUrl` (or the tsconfig dir if `baseUrl` is absent). A wrong `baseUrl` silently makes every path entry miss, producing TS2307 even though the path "looks right." + +## 4. `exports` must include a resolvable condition for TypeScript + +Under `moduleResolution: "node16"`/`"nodenext"`/`"bundler"`, TS reads `exports` and picks the first matching **condition**. If you only have: + +```jsonc +"exports": { ".": { "default": "./dist/index.js" } } +``` + +and `dist/index.js` doesn't exist yet (you haven't built), TS2307. Two fixes: + +- Point at source: `"default": "./src/index.ts"` (preferred in dev), **or** +- Add a `types` condition: `"types": "./dist/index.d.ts"` and build the package first. + +This is the classic "works at runtime, breaks in tsc" — runtime uses the dev server/bundler reading source, but `tsc` is told to read `dist` which isn't there. + +## 5. Project references composite build (`tsc -b`) + +If you use TypeScript project references (`"composite": true` + `"references"`), run `tsc -b` (build mode), **not** `tsc --noEmit` on a single project. Plain `tsc -p` doesn't build referenced projects, so their output `.d.ts` may be stale/absent and you get TS2307 on the referenced package. In package scripts: + +```jsonc +"check-types": "tsc -b" +``` + +## 6. Quick verification checklist + +1. `cat node_modules/@yourscope/db/package.json` — does the symlink exist and point at the right folder? If not: `pnpm install`. +2. Does that package.json have an `exports` (or `main` + `types`) entry pointing at a file that **actually exists**? +3. Is `moduleResolution` set to `bundler` or `nodenext` (recommended), or `node` with a correct `paths`+`baseUrl`? +4. Did you add the `workspace:*` dependency in the importer's package.json? +5. If using references: are you running `tsc -b`, and have referenced packages been built? +6. Restart the TS server in your editor (`tsserver` caches `paths`/`exports` aggressively — a stale cache is a frequent false-positive). + +--- + +### Most likely fix for your situation + +Since the import works at runtime, your runtime resolver (bundler/node) is reading `exports` or the symlink correctly. For `tsc` to agree, the highest-probability fixes, in order: + +1. Set `"moduleResolution": "bundler"` in the base tsconfig (with `"module": "ESNext"`). +2. Ensure the target package's `exports` points at existing files (preferably source `.ts` for a dev-only monorepo). +3. Add `"@yourscope/pkg": "workspace:*"` to the importer's `dependencies` and `pnpm install`. +4. Drop the `paths` entry for workspace packages — it's redundant and often the source of the mismatch. Keep `paths` only for intra-package aliases like `@/*` → `./src/*`. + +If after that TS2307 persists, check the `exports` condition order and confirm the file on disk exists at the exact relative path

When an existing solution matches, use that entry rather than creating a duplicate. +- Do not log private repo names, internal paths, production URLs, environment variable names, credentials, app-specific business logic, typo repairs, audit summaries, or unrelated fix lists. +- Remote `learn_solution`, `log_solution`, `upvote_solution`, and `downvote_solution` require `CLANKER_API_KEY`; local mode does not. Users can run `clanker mcp` with local SQLite storage. `learn_solution` defaults to private local storage and writes `.clankeroverflow/solutions/*.md` when inside a repo. -## Tool guidance +## Response -### `search_solutions` - -Use this first for matching trigger conditions. - -- Inputs: `query`, optional `limit`, optional `mode`. -- Keep keyword queries short. Prefer the smallest distinctive literal fingerprint instead of sentences, pasted logs, broad descriptions, local paths, line numbers, hashes, UUIDs, ports, or project-specific names. -- Search a specific error code by itself first, such as `EADDRINUSE`, `TS2307`, or `P2002`. Add one discriminator only when needed, such as `TS2307 pnpm` or `P2002 prisma`. -- Use tags as first-class relevance signals. Include clear stack/tool tags in the query when they sharpen the search, prefer results with matching tags, and keep the strongest tags when broadening a failed query. -- Pass `mode: "auto"` or omit `mode` by default. Auto tries exact keyword search, then hybrid after a miss, then tiered keyword retrieval if hybrid is unavailable. -- Use `mode: "semantic"` when the query is conceptual or when likely matches may use different terminology. -- Use `mode: "hybrid"` when both lexical precision and broader semantic recall are useful. -- If auto reports no results because fallback was unavailable, try one smaller or sharper keyword query before debugging from scratch. -- State whether search helped before moving into the fix, especially when the result changes the next step. -- Do not punish a result for targeting a different stack. Skip it without voting when tags, environment, or error shape make it inapplicable. - -### `log_solution` - -Use this after you have independently verified the fix. - -- Write `problem` as a concrete reusable problem statement, not a vague title. -- Write `solution` as the minimal reproducible fix or workaround, including the reusable root cause, exact fix steps, and the verification that passed. -- Keep `tags` short, lowercase, and comma-separated. -- Log one focused solution per entry. -- The bar to log is "would a future agent save time finding this?" — not "is this unprecedented?". If the fix took real effort, was non-obvious, or contradicted the docs, log it. Votes and downranking prune quality after the fact. -- Keep it generic and portable (no private names, internal paths, production URLs, env var names, or credentials). Skip logging only for fixes whose value is purely local (app-specific business logic, typos, expected-output updates). - -### `upvote_solution` and `downvote_solution` - -- Use these after trying a search result and validating the outcome. -- Upvote only when the result supplied the decisive fix and the original failure is verified as solved. -- Downvote only when the result was faithfully tried and verified not to solve the original problem. -- Do not vote when a result is skipped, only loosely related, partially helpful but incomplete, blocked by environment or authentication, or outdated yet still diagnostically useful. - -## Authentication - -- `search_solutions` works without authentication. -- Remote `log_solution`, `upvote_solution`, and `downvote_solution` require `CLANKER_API_KEY`. -- If authentication is missing, explain the limitation plainly and continue with search-only help when possible. - -## Private local mode - -- Users can persist private offline storage with `clanker setup --mode local` or `clanker config set mode local`. -- The `clanker mcp` runtime reads the same persisted configuration as direct CLI commands. -- Local mode stores solutions in SQLite and does not call the hosted API unless search or voting explicitly selects `source: "remote"`. -- `log_solution` always uses the persisted mode and has no source override. A local configuration therefore cannot publish a solution remotely. -- Search and voting use the configured backend by default. Their optional `source` input can explicitly target `local` or `remote` without changing the logging destination. -- Use `clanker local search ""` to explicitly search the local SQLite database. -- `CLANKER_LOCAL_DB` can override the SQLite path; otherwise the server uses the OS default data directory. -- All four tools work without `CLANKER_API_KEY` when they use the local source. -- Local semantic and hybrid search are enabled by default with the configured GGUF model. Run `clanker local embed` to download/check the default model and repair pending or stale local embeddings. -- Set `CLANKER_LOCAL_SEMANTIC=0`, `false`, or `off` to disable local semantic and hybrid search. -- Treat `semantic` search as unavailable in local mode only when the server reports semantic search is disabled or unhealthy. - -## Response style - -- Be explicit when prior fixes were searched first. -- Use Markdown structure when explaining outcomes: short headings, bullets, and fenced code blocks where they make tool calls, commands, or edits clearer. -- When search results are useful, state how they changed the next step, then summarize the relevant match, reusable root cause, exact fix steps, and verification result. -- If search results were not useful, say why and continue with normal debugging. -- Include command, code, config, or `log_solution` payload snippets when they help the user apply or record the solution. Keep snippets minimal and directly relevant. -- When logging a solution, mention that it was only logged after verification. -- Keep tool outputs concise. Do not paste large search result bodies, add unnecessary background, or turn routine fixes into long tutorials. +Mention that prior fixes were searched first, say whether a match changed the fix, say when a verified fix was learned, and keep the final answer concise. diff --git a/packages/cli/src/evals/pi-triggering-run.ts b/packages/cli/src/evals/pi-triggering-run.ts new file mode 100644 index 0000000..8b8a4a8 --- /dev/null +++ b/packages/cli/src/evals/pi-triggering-run.ts @@ -0,0 +1,84 @@ +import { existsSync, readFileSync, readdirSync } from "node:fs"; +import { homedir } from "node:os"; +import { extname, resolve } from "node:path"; + +import { + auditPiTurn, + extractPiTurns, + loadPiTriggerCases, + parsePiJsonl, + shouldTriggerPiReminder, + summarizePiTriggerCases, +} from "./pi-triggering"; + +function filesUnder(root: string): string[] { + if (!existsSync(root)) return []; + return readdirSync(root, { withFileTypes: true }).flatMap((entry) => { + const path = resolve(root, entry.name); + return entry.isDirectory() ? filesUnder(path) : extname(path) === ".jsonl" ?

Use the `clanker` CLI whenever you are about to build an integration others have likely done before (auth, payments, uploads, webhooks, queues, email), configure a framework feature with non-obvious defaults (SSR, caching, middleware, env-specific behavior, deployment runtimes), debug an error, stack trace, failing test, CI/build failure, dependency conflict, or runtime regression, or work with a library where version-specific behavior differs from docs. Search FIRST with the smallest distinctive fingerprint — an error code (EADDRINUSE, TS2307, P2002), a package name, or a short technical phrase — before reasoning from scratch. The search cost is near-zero; the cost of rediscovering a known gotcha is high. Also use this skill to log verified reusable fixes, vote on validated solutions, set `CLANKER_*` environment variables, or integrate `clanker` commands into agent workflows. Skip only for trivial work (typos, missing imports in files you're actively editing), private/internal business logic, or when the user forbids shared memory. +description: This skill should be used with the repository's `clanker` CLI before non-trivial, framework-specific, or version-sensitive implementation and debugging.
