Selection evidence

Confusable tool pairs.

24 pairs where similar names or overlapping descriptions may send an agent toward the wrong tool.

Tool A	Tool B	Confidence	Why they collide
`ig_get_comments`	`ig_get_comment`	medium	Singular/plural naming for near-identical getters; a task like 'get comment data' or 'get the comments' gives no cue whether the agent has a media_id or comment_id, so the wrong member can be picked.
`ig_get_messages`	`ig_get_message`	medium	Both fetch Instagram DM data and differ only by singular/plural plus id type (conversation_id vs message_id); 'get my DMs' or 'get that message' is ambiguous.
`threads_get_posts`	`threads_get_post`	medium	Only plural/singular plus 'list of published posts' vs 'details of a specific post' distinguishes them; 'show me posts/this post' can go to either.
`ig_get_comment`	`ig_get_mentioned_comments`	medium	Both take a comment_id and return comment details; a task like 'get the comment I was mentioned in' could be routed to the generic specific-comment getter unless '@mention' is explicit.
`ig_get_comments`	`ig_get_mentioned_comments`	medium	A task 'get comments where I'm mentioned' vs 'get comments on this post' both match a comment-fetching tool; agent may select the generic one when 'mention' is phrased loosely.
`ig_get_hashtag`	`ig_get_hashtag_recent`	medium	'Get the hashtag #x' is ambiguous between hashtag metadata (ig_get_hashtag) and the recent media for it; both keyed on the same hashtag_id.
`ig_get_hashtag`	`ig_get_hashtag_top`	medium	Same id key and same ambiguity: 'info about this hashtag' could mean metadata or the top popular media for it.
`ig_get_hashtag_recent`	`ig_get_hashtag_top`	high	Identical inputs and both return media tagged with a hashtag; a natural task 'get the posts for hashtag X' gives no signal for recent vs top.
`ig_get_media`	`ig_get_media_insights`	medium	Both target the same post via media_id; 'get the data/stats/performance for this post' is ambiguous between post details and analytics.
`ig_get_media_list`	`ig_get_media`	medium	'Get my media/posts' could mean the full published list or a specific post's details; plural phrasing can route to the wrong member without an id.
`ig_get_media_insights`	`ig_get_account_insights`	medium	A task 'show me my Instagram insights/analytics' is ambiguous between per-post metrics (media_id) and account-level metrics (period/metric).
`ig_get_media`	`ig_get_tagged_media`	medium	'Get media' is ambiguous between a specific post and media where the account is tagged; only 'specific post' vs 'tagged' wording separates them.
`ig_get_media_list`	`ig_get_tagged_media`	medium	'Show me the media on this account' could mean published media (list) or media the account is tagged in; descriptions are easy to conflate.
`ig_get_conversations`	`ig_get_messages`	medium	'Check my DMs/messages' is ambiguous between the conversation list and the messages inside one conversation, and both share very similar names/descriptions.
`ig_get_collaboration_invites`	`ig_respond_collaboration_invite`	medium	'Handle the collaboration invite' is ambiguous between reading pending invites and accepting/declining one; both share the invite/collaboration wording.
`ig_get_container_status`	`threads_get_container_status`	medium	Descriptions differ only by platform; 'check the media processing status of this container' without an explicit platform can pick the wrong server tool.
`ig_publish_carousel`	`threads_publish_carousel`	medium	Near-identical descriptions differing only by platform; 'publish a carousel' is ambiguous unless the user names Instagram or Threads.
`ig_get_profile`	`threads_get_profile`	medium	Both return profile info and differ only by platform; 'get the profile information' without platform context can select the wrong one.
`ig_get_replies`	`threads_get_replies`	medium	Both are 'get replies' taking an id; a task 'get the replies' is ambiguous between Instagram comment replies and Threads post replies.
`ig_hide_comment`	`ig_delete_comment`	medium	'Remove/get rid of this comment' is ambiguous between hiding it and permanently deleting it; descriptions are close enough to route wrongly.
`ig_post_comment`	`ig_reply_to_comment`	medium	'Comment on this / reply to this post' is ambiguous between posting a top-level comment and replying to an existing comment, especially when a specific thread is referenced.
`threads_get_post`	`threads_get_post_insights`	medium	Both target a single post via post_id; 'get the post data/metrics' is ambiguous between post details and its analytics.
`threads_get_post_insights`	`threads_get_user_insights`	medium	'Get my Threads insights/stats' is ambiguous between per-post metrics (post_id) and account-level metrics (metric only).
`threads_get_post`	`threads_get_replies`	medium	'Show me this thread/post' could mean post details or the replies/conversation for it since Threads calls replies the conversation.
