# claude_pipe — artifact probe (playground)
|
||||
|
||||
Herramienta desechable para auditar la calidad del parseo de la TUI que hace
|
||||
`claude_pipe`. No se indexa, no tiene `app.md`, vive dentro de `apps/claude_pipe/`
|
||||
y se mueve con su sub-repo.
|
||||
|
||||
## Qué comprueba
|
||||
|
||||
Por cada prompt, lanza el binario `claude_pipe` en modo one-shot y en modo
|
||||
`--stream`, y busca:
|
||||
|
||||
1. **Artefactos** que se cuelan del render en la respuesta parseada: caracteres de
|
||||
caja (`╭│╰`), reglas horizontales (`────`), fragmentos de la status bar
|
||||
(`CTX:`, `IN:`, `$…`, `← for agents`), la línea meta `✻ Crunched`, el prompt
|
||||
`❯`, el carácter de reemplazo `�`, palabras pegadas (>40 chars sin espacio), o
|
||||
el prompt repetido literalmente.
|
||||
2. **Consistencia del streaming**: la concatenación de los `text_delta` debe
|
||||
reconstruir el `result` final. Si no, la heurística de prefijo perdió o duplicó
|
||||
texto bajo reflow.
|
||||
3. **(Opcional, `--ref`)** discrepancia contra `claude -p` real para el mismo
|
||||
prompt (normalizado por espacios). claude no es determinista, así que solo los
|
||||
prompts triviales se espera que coincidan exactamente.
|
||||
|
||||
Sale con código 2 si encuentra artefactos o inconsistencias (para poder usarlo
|
||||
como gate).
|
||||
|
||||
## Cómo lanzarlo
|
||||
|
||||
```bash
|
||||
cd apps/claude_pipe
|
||||
CGO_ENABLED=1 go build -tags fts5 -o claude_pipe . # asegúrate de tener el binario
|
||||
|
||||
cd playground
|
||||
|
||||
# Set de prompts por defecto, sin comparar con claude -p
|
||||
go run artifact_probe.go --root /home/enmanuel/fn_registry
|
||||
|
||||
# Comparando además contra `claude -p` real (gasta llamadas reales)
|
||||
go run artifact_probe.go --root /home/enmanuel/fn_registry --ref
|
||||
|
||||
# Un solo prompt custom
|
||||
go run artifact_probe.go --root /home/enmanuel/fn_registry --prompt "tu prompt aqui"
|
||||
```
|
||||
|
||||
`--root` debe ser un repo cuyos MCP de claude ya estén aprobados, para que la TUI
|
||||
no muestre el diálogo de arranque.
|
||||
|
||||
## Chat en el navegador (`web/`)
|
||||
|
||||
Un chat web que prueba todo el stack end to end: backend Go con SSE que lanza
|
||||
`claude_pipe --stream` por cada mensaje y reenvía los `text_delta` al navegador,
|
||||
frontend chat vanilla (sin frameworks, sin node_modules).
|
||||
|
||||
```bash
|
||||
cd apps/claude_pipe
|
||||
CGO_ENABLED=1 go build -tags fts5 -o claude_pipe . # binario con el fix del spinner
|
||||
|
||||
cd playground
|
||||
go run ./web # http://localhost:8099
|
||||
# o con flags:
|
||||
go run ./web --port 8099 --root /home/enmanuel/fn_registry --warmup 4s --idle 4s --max 120s
|
||||
```
|
||||
|
||||
Abre `http://localhost:8099` y escribe. Cada mensaje es una sesión `claude` nueva
|
||||
(sin memoria entre turnos: `claude_pipe` es one-shot). Hay ~8s de `warmup`+`idle`
|
||||
antes de la primera respuesta. La respuesta se reconstruye desde la TUI parseada,
|
||||
ya sin el spinner de carga.

// artifact_probe drives the claude_pipe binary across a set of prompts and looks
|
||||
// for two classes of problems that are inherent to parsing the claude TUI:
|
||||
//
|
||||
// 1. Artifacts: bits of the render that leaked into the parsed answer — box
|
||||
// drawing characters from the banner, status-bar fragments (CTX:, IN:, $...),
|
||||
// the "✻ Crunched" meta line, the echoed prompt, replacement characters, or
|
||||
// glued words (a heuristic: very long runs with no spaces).
|
||||
//
|
||||
// 2. Streaming inconsistencies: in --stream mode, the concatenation of all
|
||||
// text_delta events should reconstruct the final result. If it doesn't, the
|
||||
// prefix-delta heuristic dropped or duplicated text under reflow.
|
||||
//
|
||||
// Optionally (--ref) it also runs the real `claude -p` for the same prompt and
|
||||
// reports whether claude_pipe's answer matches it (whitespace-normalized). claude
|
||||
// is not deterministic, so only trivial prompts are expected to match exactly;
|
||||
// for open prompts the comparison is informational.
|
||||
//
|
||||
// This is a playground tool: it is not indexed, has no registry entry, and exists
|
||||
// only to probe claude_pipe's TUI-parsing quality. Run it when you want to audit
|
||||
// the parser against real claude output.
|
||||
//
|
||||
// Usage:
|
||||
//
|

// go run artifact_probe.go --root /home/enmanuel/fn_registry # default prompts, no ref
|

// go run artifact_probe.go --root /home/enmanuel/fn_registry --ref # also compare vs claude -p

// Command server is a browser chat playground for claude_pipe. It serves a small

// subprocess and relays its NDJSON events (text_delta + result) to the browser as
|
||||
// Server-Sent Events. The browser renders the answer token-chunk by token-chunk.
|

// This proves the whole stack end to end through a real surface: the PTY capture,

// the VT render, the TUI parser (with the spinner fix), and the streaming delta —
