Curviate: posts, comments, reactions, feed

Engagement is the cheapest way to be visible, and every write here is public and attributable. Two vocabularies and three identifier forms cause most failures; both are below.

Command surface established against CLI 0.33.0.

Before any command

npm install -g @curviate/cli && curviate --version    # needs Node 18 or newer
curviate login --api-key <key>                        # or export CURVIATE_API_KEY
curviate account list --json                          # the acc_id for --account

• Credentials resolve flag > environment > stored profile (CURVIATE_API_KEY, CURVIATE_BASE_URL, CURVIATE_ACCOUNT).
• --profile <name> picks the stored credential set; --account <acc_id> picks which connected LinkedIn account posts, comments or reacts. Name it explicitly on every write: a comment from the wrong account is public and permanent.
• --preview before every write. It renders the resolved request without sending. On a read command it is refused with exit 2.
• --json on anything you parse; --fields a,b,c to project; --verbose when a slim response looks suspiciously empty.
• Put global flags at the end of the command.
• Branch on the exit code, never on prose. See the table at the end.
• These are not retrieval-mode commands: --mode/--max-age are refused here with unknown flag, exit 2 (see curviate-profile for the four commands that do accept them).

Text input

Post and comment text is a positional argument, and - reads stdin. Use a quoted heredoc: the quoted delimiter disables every shell expansion, so apostrophes, accents, $ and backticks survive intact:

cat <<'EOF' | curviate post create - --preview
Line one.

Line two.
EOF

Identifiers

A post id comes in three forms and the commands are not uniformly forgiving:

• The numeric activity id (7459869580333576193) is the canonical form.
• urn:li:activity:<N> works.
• A full share URL is accepted and the id extracted from it. If a command ever rejects one, extract it yourself: POST_ID=$(echo "<share_url>" | grep -oP 'activity[-/]\K\d+').
• Some builds have rejected the bare numeric id at write time on post react, comment add and comment list while --preview on the same command rendered fine. If you hit that, pass the base64 id from whatever post get, post create or list response you already hold: no extra fetch needed.

In every comment command, <post_id> is the original post's id, never the comment's. <comment_id> comes from comment list <post_id> as items[].id.

post get answers with social_id (a URN); the numeric id you passed is not echoed back.

post

Command	What it does	Confidence
curviate post get <post_id>	One post. Adds is_repost, reposted_by, user_reacted and a richer author (headline, slug) over what a list carries.	proven
curviate post create "<text>"	Publish a post. --attach is repeatable for images and takes jpg, png, gif, mp4 or pdf; a single PDF produces a document post.	proven
curviate post react <post_id> <reaction>	React to a post. --as-organization <id> reacts as a company page you administer. Duplicate reactions succeed silently.	proven
curviate post unreact <post_id> <reaction>	Remove your reaction.	proven
curviate post reactions <post_id>	Reactions on a post: {value, author: {id, type, name, headline, profile_url, profile_picture_url, network_distance?}}. Page default 20, maximum 50. No timestamp exists.	proven
curviate post delete <post_id>	Delete a post you own.	proven
curviate post save <post_id>	Save to your private bookmark list. Never notifies the author, never visible to anyone else. Idempotent.	proven
curviate post unsave <post_id>	Remove from the bookmark list. Idempotent.	proven
curviate post saved	Your saved posts, newest first. Each item is a preview with the snippet capped at 140 characters.	proven
curviate post user-posts <id|me>	A member's own posts. Same data as profile <id> --posts.	proven
curviate post user-reactions <id|me>	A member's own reactions. Same data as profile <id> --reactions.	proven

Reaction vocabularies: write is not read

Write (post react, comment react, lowercase)	Read (value, user_reacted)
like	LIKE (confirmed pairing)
celebrate	PRAISE (confirmed pairing)
insightful	INTEREST (confirmed pairing)
support	APPRECIATION (pairing unconfirmed)
love	EMPATHY (pairing unconfirmed)
funny	ENTERTAINMENT (pairing unconfirmed)

Sending an uppercase read value as a write returns INVALID_REQUEST, exit 2. Always write lowercase. Read-side casing has been observed to vary, so compare reaction values case-insensitively when parsing post reactions, comment reactions, or user_reacted.

Traps

• post reactions returns cursor: null while more reactions remain. A single page is not the reaction list. Use --all, and check the final line for {"object": "stream_truncated", …, "has_more": true}.
• Check user_reacted on post get before reacting: a duplicate reaction succeeds silently and tells you nothing.
• A very recent create or delete can take minutes to appear in post user-posts (LinkedIn-side indexing). post get <post_id> reflects it immediately.
• The post list carries no is_repost field. Detect a repost by comparing the item's author name against the member you queried, or call post get <post_id> --fields is_repost,reposted_by. On a repost, author is the original creator and reposted_by is the sharer.
• A company reactor carries no network_distance: the key is absent, not null. Treat author.type == "COMPANY" as its own signal rather than as missing data.
• A list item already carries id, parsed_datetime, full text, reaction_counter, comment_counter, repost_counter, impressions_counter, author and attachments, so most "read a post" questions need no post get at all.

comment

Command	What it does	Confidence
curviate comment list <post_id>	Top-level comments. Returns id and social_id (chain into comment react/reply), reply_counter (above 0 means nested replies exist) and author.profile_url.	proven
curviate comment add <post_id> "<text>"	Comment on a post. Returns the new comment's id. --attach takes at most one image.	proven
curviate comment reply <post_id> <comment_id> "<text>"	Reply to a specific comment.	proven
curviate comment edit <post_id> <comment_id> "<text>"	Edit your own comment.	proven
curviate comment delete <post_id> <comment_id>	Delete your own comment.	proven
curviate comment replies <post_id> <comment_id>	Replies to one comment.	proven
curviate comment react <post_id> <comment_id> <reaction>	React to a specific comment (not the post). Same lowercase write vocabulary.	proven
curviate comment unreact <post_id> <comment_id> <reaction>	Remove that reaction.	proven
curviate comment reactions <post_id> <comment_id>	Reactions on one comment.	proven
curviate comment user <id|me>	Comments a member authored. Same data as profile <id> --comments; each carries post_id for context.	proven

• comment list returns only what is visible to you. The post's own comment_counter is always greater than or equal to the items returned, so a mismatch is not a bug.
• parsed_datetime is always null on a comment: use date for the ISO timestamp.
• To check whether you already commented on a post, match on parent_post.share_url, never on ids. parent_post.id is base64 of a two-element array ([comment_activity, post_activity]) while a post's own id is a one-element array, so an id comparison is always false. If you need the id, decode and take element [1].
• A very recent add or delete can take minutes to appear in comment list.

feed and notification

Command	What it does	Confidence
curviate feed home	The connected account's home feed as agent-actionable posts. --sort recent (default, reverse-chronological, always available) or --sort relevant (LinkedIn's ranked feed, which draws on a shared throttled budget). --sort is ignored when --cursor is supplied.	proven
curviate notification list	Notification cards, newest first, with the unread badge and a poll watermark. --filter selects the stream: all (default), jobs, mentions, my_posts, my_posts_comments, my_posts_reactions, my_posts_reposts.	proven
curviate notification delete <card_urn>	Delete one of your own notification cards. Idempotent, cannot be undone.	proven
curviate notification show-less <card_urn>	Apply "show less like this" to a card's source. For network-activity cards this removes the card, the same as delete. Idempotent, cannot be undone.	proven

The feed and the notification stream are the two cheapest sources of a genuinely current thing to engage with: reach for them before searching for something to react to.

Exit codes to branch on here

Code	Meaning	What to do
1	INTERNAL from the server itself: a genuine bug on the platform side.	Worth one retry; if it repeats it is a bug to report, not a state to work around.
2	Usage or invalid input, often raised before any network call: an uppercase reaction value, a malformed post id, more than one attachment on a comment.	Fix the invocation. Never retry unchanged.
4	Not found, usually a wrong identifier form rather than a missing post.	Re-derive the id before concluding the post is gone.
5	Three causes, one code: read error.code. NO_ACTIVE_SEAT: the account is on no active seat. LINKEDIN_FEATURE_NOT_SUBSCRIBED: LinkedIn itself lacks the feature. BETA_NOT_ENABLED: the operation is beta-gated and this workspace has not opted in (pass --beta for one call, or a human enables it in Settings).	Branch on error.code: the three fixes have nothing in common, and none is fixed by retrying unchanged.
6	PLATFORM_RATE_LIMIT and its siblings. Carries retry_after in whole seconds. A response naming budgetRow means only that row is paused; every other row on the account keeps working.	Back off and retry after that many seconds. On a named budgetRow, switch to other work on the account rather than backing off across the board.
7	Transient platform fault: a hiccup, or a request that got no response at all (network error, DNS failure, timeout) or one that came back as something other than a valid API answer. Carries retryLikelyToSucceed: true.	Retry with backoff.
8	Account or connection state. Read error.code.	LINKEDIN_OPERATION_NOT_SUPPORTED is permanent and never retryable; a session error needs a reconnect.
13	BUDGET_EXHAUSTED: a safety rule of your own refused the action, not LinkedIn. Read error.safetyReason: ceiling means the row named in error.budgetRow hit its configured limit; activity_window means the account is outside the hours it works in (no budgetRow on that one). Nothing reached LinkedIn and nothing was spent; nothing was posted. reset_at can be weeks out, and may be null where no clock frees it.	Do not back off and retry. error.safetyHint.parameter names the exact setting to change. Read quotas[] via curviate account get <acc_id> --json, then wait for the named reset or change that setting.
