Code-reuse polish (post-implementation review pass):
- Extract text.OneLine(maxWidth, s) helper combining preview-row
normalization (newline/CR/tab → space) with text.Truncate's
UTF-8-safe truncation. Replaces agent/view.go truncate1Line (ASCII
'...' + byte-slice CJK-unsafe) and chunk/list.go singleLine.
- Lift cmdutil.OpenInput(path) for the '-' = stdin / else os.Open
pattern shared across agent create/edit and the api command.
Replaces agent/create.go's private openInput.
- Strip inline doc-spec parentheticals from source comments — those
belong in commit messages and project docs, not in source where
they rot.
Pre-PR audit fixes:
- doc upload: reject `--metadata` paired with `--from-url` as
input.invalid_argument up-front (the URL-ingest request type has
no metadata field server-side, so the pair would otherwise silently
drop). Long help and CHANGELOG updated to call out the asymmetry.
- doc upload (file path): map sdk.ErrDuplicateFile sentinel to
resource.already_exists. The sentinel arrives with no "HTTP error <n>:"
prefix because the SDK short-circuits on file-hash before reading the
HTTP status, so the previous WrapHTTP fall-through misclassified it
as network.error with a misleading "check base URL reachability" hint.
The --from-url branch already handled ErrDuplicateURL this way; this
closes the asymmetry. Caught by e2e re-upload of an already-ingested
file; regression test added.
- README exit-10 enumeration adds `agent delete` and `chunk delete`
(these were missing alongside the v0.5 destructive verbs they were
meant to gate).
Docs sync:
- cli/README.md: command tree now includes the chunk subtree; adds
agent / chunk lines to the 5-minute quickstart; adds a "Contributing
/ Reporting issues" section pointing at the repo's SECURITY.md and
AGENTS.md; drops third-party CLI parallels from the surface
description.
- cli/AGENTS.md: "Command surface design SOP" gains the
flag-vs-escape-hatch step. "CRUD command flag canon" renamed to the
hard-required-flags pattern with the contrast (TTY-prompts-fill)
defined inline rather than via opaque shorthand.
- cli/CHANGELOG.md: search docs case-sensitivity shift promoted to its
own #### Breaking changes subsection. MCP doc_list filter count
corrected from 5 to 6. Drops the bogus go.mod yaml.v3 entry (yaml.v3
was already a dependency on main; v0.5 added zero go.mod lines).
Replaces internal-Go identifiers (fuzzyTime, NoOptDefVal) with
user-language and drops the § section-symbol jargon.
