# Remote-API fallback source: queries any OpenAI-compatible chat
|
|
# completions endpoint (OpenAI itself, OpenRouter, Groq, Together,
|
|
# Anthropic's OpenAI-compatibility layer, a company-internal proxy,
|
|
# etc.) for a fix, only when nothing cheaper -- including the free
|
|
# local model in 70-local-llm.sh -- already matched.
|
|
#
|
|
# Off by default. Requires FX_REMOTE_API_URL, FX_REMOTE_API_KEY, and
|
|
# FX_REMOTE_API_MODEL to all be set explicitly; no default model is
|
|
# assumed, since guessing one could silently pick something you don't
|
|
# want to pay for. Silently no-ops if any of the three is missing.
|
|
#
|
|
# FX_REMOTE_API_URL is the exact URL to POST to -- no "/chat/completions"
|
|
# auto-appended. An earlier version guessed that suffix onto whatever
|
|
# base URL was given, which works for OpenAI/OpenRouter/Groq's actual
|
|
# convention but broke, silently, against a real third-party API that
|
|
# used a different path (a local FastAPI service with a plain "/chat"
|
|
# endpoint, not "/chat/.../completions" -- confirmed live: the guessed
|
|
# URL 404'd, the real one worked). Silent failure on a wrong guess is
|
|
# worse than requiring the full URL up front.
|
|
#
|
|
# Numbered 80: after the free local-LLM source (70) and before
|
|
# 90-team-shared.sh, which is a human-curated source and gets the final
|
|
# word. This is the most expensive tier in latency and real dollar
|
|
# cost, so it should only ever be the last thing tried.
|
|
#
|
|
# TRUST WARNING, sharper than every other source here: this is the one
|
|
# tier where the text you'd be eval'ing was not authored by you, a tool
|
|
# you run, or a URL you personally chose to trust -- it's a third-party
|
|
# service's best guess. fx.sh already labels every candidate with its
|
|
# source filename in the picker ("[80-remote-api.sh] ..."), so this is
|
|
# never visually indistinguishable from a self-diagnosed or locally-
|
|
# verified fix. Read that label before accepting.

PROMPT = f"""You are suggesting a fix for a failed shell command, to be taught to a self-healing shell function called f().
|
|
Rules:
|
|
- f() will eval your fix ONCE as a precondition, then re-run the ORIGINAL command verbatim. Your fix never replaces the command; it only sets up state so the original command then succeeds.
|
|
- If the fix should generalize beyond this one invocation, define a shell function with the same name as the failing program, wrapping the real binary via `command <prog> "$@"`, and only special-case the failure inside it.
|
|
- Respond with EXACTLY ONE LINE of POSIX shell and nothing else: no explanation, no markdown, no code fences, no commentary.

Failing command: {cmd}
