blowhorn slack

blowhorn slack: delete, edit, profiles, react, send, whoami.

The blowhorn slack commands. Each one's --help prints the same text.

Command What it does
slack delete Delete a Slack message this profile sent with 'blowhorn slack send' (chat.delete).
slack edit Replace the text of a Slack message this profile sent with 'blowhorn slack send' (chat.update).
slack profiles List every profile's captured Slack workspaces (or only the --profile names given), the credentials each holds (session, user-token, bot-token) and which one --slack-auth would use.
slack react Add an emoji reaction to any Slack message as the profile (reactions.add), or take yours back with --remove (reactions.remove).
slack send Send one message to Slack as one profile, or as each of several (--profile a,b: one after another, each with its own idempotency key, ledger entry and result; one profile's failure never stops the...
slack whoami Ask Slack (auth.test) who a profile's Slack credential is in one workspace: user, user id and team, with the credential --slack-auth allowed and whether that was a fallback.

blowhorn slack delete

Delete a Slack message this profile sent with 'blowhorn slack send' (chat.delete). Only your own messages, by the store's send ledger (not_sent_by_profile otherwise, before any Slack call), even when the session is a workspace admin's. A dry run unless --confirm. Exit codes as 'slack send'.

output 
blowhorn slack delete [OPTIONS]
Flag Type Default Description
--target string The message: a Slack message link, or its ts with --channel and --workspace
--channel string The channel id (C…, D… or G…) when --target is a bare ts
--workspace string The workspace host (e.g. mesheryio.slack.com) when --target does not name one; for whoami, which workspace to ask
--confirm boolean false Actually send. Without it the command is a dry run that sends nothing
--slack-auth string Which Slack credential may send, for one run: 'session' (your captured signed-in web session; the message is yours, with no app attached), 'user-token' (an xoxp- app token for you) or 'bot-token' (an xoxb- bot token), or a comma-delimited list of them tried in order (e.g. 'session,user-token,bot-token'). One value is directive: that credential or a refusal naming why. A token may show the Slack app's attribution. This flag, then BLOWHORN_SLACK_AUTH, then defaults.slack.auth_mode in .blowhorn.yaml, then the built-in, selects it; any other value is refused before anything runs. Dry runs and results name the credential that ran and whether it was a fallback
--json boolean false Print the result as JSON (no secrets)
--platform string Accepted and ignored by 'blowhorn slack': this command never acts on a platform, so --platform has no effect here -- including a value inherited from BLOWHORN_PLATFORM or defaults.platform in .blowhorn.yaml
--pace string Pace of the one random wait 'blowhorn slack delete' takes: before each confirmed delete after the first when --profile names several profiles (a single profile, or a dry run, never waits): a preset name (fast/normal/slow) or a numeric multiplier (e.g. 0.5, 2.0). Resolved as CLI flag, then BLOWHORN_PACE, then defaults.pace in .blowhorn.yaml (normal when none is set); an unrecognized value is rejected before anything runs

Also takes the shared flags: --config, --log-dir, --profile, --exclude, --headless, --chrome-launch, --headed, --dry-run, --verbose.

Examples:

terminal 
blowhorn slack delete --profile rian --target 'https://mesheryio.slack.com/archives/C0123/p1776000000000400' --slack-auth session --confirm

Output: json with --json, text otherwise.

blowhorn slack edit

Replace the text of a Slack message this profile sent with 'blowhorn slack send' (chat.update). Only your own messages: the store's send ledger must show this profile sent that ts, or the result is not_sent_by_profile before any Slack call. A dry run unless --confirm. --target is the message link (its own ts, never the ?thread_ts= parent) or a bare ts with --channel and --workspace; the text comes from --message, --file or stdin ('-') and is sent untouched. Several profiles (--profile a,b) run one after another. Exit codes as 'slack send'.

output 
blowhorn slack edit [OPTIONS]
Flag Type Default Description
--target string The message: a Slack message link, or its ts with --channel and --workspace
--channel string The channel id (C…, D… or G…) when --target is a bare ts
--workspace string The workspace host (e.g. mesheryio.slack.com) when --target does not name one; for whoami, which workspace to ask
--confirm boolean false Actually send. Without it the command is a dry run that sends nothing
--message string The message text, sent untouched (Slack mrkdwn included); '-' reads it from stdin
--file string Read the message text from this file ('-' for stdin), sent untouched
--slack-auth string Which Slack credential may send, for one run: 'session' (your captured signed-in web session; the message is yours, with no app attached), 'user-token' (an xoxp- app token for you) or 'bot-token' (an xoxb- bot token), or a comma-delimited list of them tried in order (e.g. 'session,user-token,bot-token'). One value is directive: that credential or a refusal naming why. A token may show the Slack app's attribution. This flag, then BLOWHORN_SLACK_AUTH, then defaults.slack.auth_mode in .blowhorn.yaml, then the built-in, selects it; any other value is refused before anything runs. Dry runs and results name the credential that ran and whether it was a fallback
--json boolean false Print the result as JSON (no secrets)
--platform string Accepted and ignored by 'blowhorn slack': this command never acts on a platform, so --platform has no effect here -- including a value inherited from BLOWHORN_PLATFORM or defaults.platform in .blowhorn.yaml
--pace string Pace of the one random wait 'blowhorn slack edit' takes: before each confirmed edit after the first when --profile names several profiles (a single profile, or a dry run, never waits): a preset name (fast/normal/slow) or a numeric multiplier (e.g. 0.5, 2.0). Resolved as CLI flag, then BLOWHORN_PACE, then defaults.pace in .blowhorn.yaml (normal when none is set); an unrecognized value is rejected before anything runs

Also takes the shared flags: --config, --log-dir, --profile, --exclude, --headless, --chrome-launch, --headed, --dry-run, --verbose.

Examples:

terminal 
blowhorn slack edit --profile rian --target 'https://mesheryio.slack.com/archives/C0123/p1776000000000400' --file fixed.md
blowhorn slack edit --profile rian --target 'https://mesheryio.slack.com/archives/C0123/p1776000000000400' --file fixed.md --slack-auth session --confirm --json

Output: json with --json, text otherwise.

blowhorn slack profiles

List every profile's captured Slack workspaces (or only the --profile names given), the credentials each holds (session, user-token, bot-token) and which one --slack-auth would use. Reads the store and makes no Slack call. A profile whose config.yaml still carries Slack keys while the store holds no session reads 'refused', with the fix the send gives. No secret is printed.

output 
blowhorn slack profiles [OPTIONS]
Flag Type Default Description
--slack-auth string Which Slack credential may send, for one run: 'session' (your captured signed-in web session; the message is yours, with no app attached), 'user-token' (an xoxp- app token for you) or 'bot-token' (an xoxb- bot token), or a comma-delimited list of them tried in order (e.g. 'session,user-token,bot-token'). One value is directive: that credential or a refusal naming why. A token may show the Slack app's attribution. This flag, then BLOWHORN_SLACK_AUTH, then defaults.slack.auth_mode in .blowhorn.yaml, then the built-in, selects it; any other value is refused before anything runs. Dry runs and results name the credential that ran and whether it was a fallback
--json boolean false Print the result as JSON (no secrets)
--platform string Accepted and ignored by 'blowhorn slack': this command never acts on a platform, so --platform has no effect here -- including a value inherited from BLOWHORN_PLATFORM or defaults.platform in .blowhorn.yaml
--pace string Accepted by 'blowhorn slack profiles' because --pace is a global flag, but this command does no paced work -- it opens no browser and sleeps between nothing -- so the value changes nothing about how it runs and appears only in the Pace column of the -v summary. Resolved as CLI flag, then BLOWHORN_PACE, then defaults.pace in .blowhorn.yaml (normal when none is set); an unrecognized value is rejected before anything runs

Also takes the shared flags: --config, --log-dir, --profile, --exclude, --headless, --chrome-launch, --headed, --dry-run, --verbose.

Examples:

terminal 
blowhorn slack profiles --json
blowhorn slack profiles --profile rian --slack-auth session

Output: json with --json, text otherwise.

blowhorn slack react

Add an emoji reaction to any Slack message as the profile (reactions.add), or take yours back with --remove (reactions.remove). A dry run unless --confirm. A reaction already there (or already gone) is success with changed: false. --emoji takes white_check_mark or :white_check_mark:. Several profiles (--profile a,b) each react, one after another. Exit codes as 'slack send'.

output 
blowhorn slack react [OPTIONS]
Flag Type Default Description
--target string The message: a Slack message link, or its ts with --channel and --workspace
--channel string The channel id (C…, D… or G…) when --target is a bare ts
--workspace string The workspace host (e.g. mesheryio.slack.com) when --target does not name one; for whoami, which workspace to ask
--confirm boolean false Actually send. Without it the command is a dry run that sends nothing
--emoji string The emoji name, with or without colons (white_check_mark, :+1:)
--remove boolean false Take the reaction back (reactions.remove) instead of adding it
--slack-auth string Which Slack credential may send, for one run: 'session' (your captured signed-in web session; the message is yours, with no app attached), 'user-token' (an xoxp- app token for you) or 'bot-token' (an xoxb- bot token), or a comma-delimited list of them tried in order (e.g. 'session,user-token,bot-token'). One value is directive: that credential or a refusal naming why. A token may show the Slack app's attribution. This flag, then BLOWHORN_SLACK_AUTH, then defaults.slack.auth_mode in .blowhorn.yaml, then the built-in, selects it; any other value is refused before anything runs. Dry runs and results name the credential that ran and whether it was a fallback
--json boolean false Print the result as JSON (no secrets)
--platform string Accepted and ignored by 'blowhorn slack': this command never acts on a platform, so --platform has no effect here -- including a value inherited from BLOWHORN_PLATFORM or defaults.platform in .blowhorn.yaml
--pace string Pace of the one random wait 'blowhorn slack react' takes: before each confirmed reaction after the first when --profile names several profiles (a single profile, or a dry run, never waits): a preset name (fast/normal/slow) or a numeric multiplier (e.g. 0.5, 2.0). Resolved as CLI flag, then BLOWHORN_PACE, then defaults.pace in .blowhorn.yaml (normal when none is set); an unrecognized value is rejected before anything runs

Also takes the shared flags: --config, --log-dir, --profile, --exclude, --headless, --chrome-launch, --headed, --dry-run, --verbose.

Examples:

terminal 
blowhorn slack react --profile rian --target 'https://mesheryio.slack.com/archives/C0123/p1776000000000100' --emoji white_check_mark
blowhorn slack react --profile rian,lee --target 'https://mesheryio.slack.com/archives/C0123/p1776000000000100' --emoji +1 --slack-auth session --confirm --json

Output: json with --json, text otherwise.

blowhorn slack send

Send one message to Slack as one profile, or as each of several (--profile a,b: one after another, each with its own idempotency key, ledger entry and result; one profile's failure never stops the next, and exit is 0 only when every profile succeeded), exactly once. A dry run unless --confirm: the dry run resolves the credential, the target and the idempotency key and says what would happen. --target takes a message link (a thread reply: the ?thread_ts= parent when the link is a reply's), a channel link (a top-level post), or #channel, @user or a channel id with --workspace. The text comes from --message, --file <path>, or stdin with --message - or --file -, and is sent untouched (Slack mrkdwn included). Every send carries a client_msg_id and is claimed in the store's send ledger under its idempotency key (--idempotency-key, else derived from profile, workspace, channel, thread and text) before it goes out: a key already sent replays its ts and link without sending again, and a send whose answer was never recorded is 'outcome unknown' and is never resent automatically. The result names the credential that ran (--slack-auth), whether that was a fallback, warns when a token may show a Slack app's attribution, and reports bot_id, app_id, bot_profile or subtype on Slack's answer. Exit codes: 0 sent, replayed or previewed; 1 refused (credential or Slack); 2 usage or key conflict; 3 store unavailable or a contended key; 4 outcome unknown; 5 rate-limited (Retry-After kept).

output 
blowhorn slack send [OPTIONS]
Flag Type Default Description
--target string Where to send: a Slack message link (thread reply), a channel link (top-level post), or #channel, @user or a channel id with --workspace
--workspace string The workspace host (e.g. mesheryio.slack.com) when --target does not name one; for whoami, which workspace to ask
--message string The message text, sent untouched (Slack mrkdwn included); '-' reads it from stdin
--file string Read the message text from this file ('-' for stdin), sent untouched
--confirm boolean false Actually send. Without it the command is a dry run that sends nothing
--idempotency-key string The key this send is recorded under; a key already sent is replayed, never sent twice (default: derived from profile, workspace, channel, thread and text)
--slack-auth string Which Slack credential may send, for one run: 'session' (your captured signed-in web session; the message is yours, with no app attached), 'user-token' (an xoxp- app token for you) or 'bot-token' (an xoxb- bot token), or a comma-delimited list of them tried in order (e.g. 'session,user-token,bot-token'). One value is directive: that credential or a refusal naming why. A token may show the Slack app's attribution. This flag, then BLOWHORN_SLACK_AUTH, then defaults.slack.auth_mode in .blowhorn.yaml, then the built-in, selects it; any other value is refused before anything runs. Dry runs and results name the credential that ran and whether it was a fallback
--json boolean false Print the result as JSON (no secrets)
--platform string Accepted and ignored by 'blowhorn slack': this command never acts on a platform, so --platform has no effect here -- including a value inherited from BLOWHORN_PLATFORM or defaults.platform in .blowhorn.yaml
--pace string Pace of the one random wait 'blowhorn slack send' takes: before each confirmed send after the first when --profile names several profiles (a single profile, or a dry run, never waits): a preset name (fast/normal/slow) or a numeric multiplier (e.g. 0.5, 2.0). Resolved as CLI flag, then BLOWHORN_PACE, then defaults.pace in .blowhorn.yaml (normal when none is set); an unrecognized value is rejected before anything runs

Also takes the shared flags: --config, --log-dir, --profile, --exclude, --headless, --chrome-launch, --headed, --dry-run, --verbose.

Examples:

terminal 
blowhorn slack send --profile rian --target 'https://mesheryio.slack.com/archives/C0123/p1776000000000100' --message 'Thanks, merged'
blowhorn slack send --profile rian --target 'https://mesheryio.slack.com/archives/C0123/p1776000000000100' --message 'Thanks, merged' --slack-auth session --confirm --json

blowhorn slack whoami

Ask Slack (auth.test) who a profile's Slack credential is in one workspace: user, user id and team, with the credential --slack-auth allowed and whether that was a fallback. Sends no message. --workspace may be left out when the profile has captured exactly one workspace.

Dry runs and results name the credential that ran and whether it was a fallback

--platform string Accepted and ignored by 'blowhorn slack': this command never acts on a platform, so --platform has no effect here -- including a value inherited from BLOWHORN_PLATFORM or defaults.platform in .blowhorn.yaml
--pace string Accepted by 'blowhorn slack whoami' because --pace is a global flag, but this command does no paced work -- it opens no browser and sleeps between nothing -- so the value changes nothing about how it runs and appears only in the Pace column of the -v summary. Resolved as CLI flag, then BLOWHORN_PACE, then defaults.pace in .blowhorn.yaml (normal when none is set); an unrecognized value is rejected before anything runs
