runtime+prompt: content verbs read stdin OR arg; content travels in the program

[vinodhalaharvi-claude]

The principle (your point about temporal portability)

On temporal a program runs on an arbitrary remote worker — it cannot read local files; only data passed in (stdin) and out (stdout) crosses that boundary. So a pipeline must carry its content as values, not reach into ambient local state (read "/tmp/x"). The same program must run unchanged on memory and temporal — read "localfile" violates that; stdin/arg content does not.

This makes the content verbs echo-like (stdin OR arg) so pasted content travels in the program.

The bug this fixes (seen live in Slack)

@loom in memory: summarize "..." returned 'no content was included' — because summarize was input-only: it ignored its arg and summarized empty upstream input.

Changes

runtime (internal/agentscript/runtime.go):

• summarize: use piped input if present, else the arg; clear error if neither
• analyze: no piped input → treat the arg as content (not just the focus)
• (ask already did arg + optional stdin context — kept as the model)

prompt (pkg/script/translate.go):

• New PASSING CONTENT section: put pasted text directly in the command's quoted arg; do not use a file path / read for pasted content — content travels in the argument so the program is portable across backends

Effect

@loom in memory: summarize <pasted text> → memory static ( summarize "<pasted text>" ) → runs in-process on Claude Code → real summary. The identical program is valid on temporal later (content is a value, not a local file).

Verified

summarize "text" and stdin >=> summarize both reach the LLM with content (sandbox lacks the claude binary — proving the route). No local-state dependency.
