1.0.0-beta.31

published 10 October 2026

• Added a setting, workspace.worktree.prepare: a command Mercury runs inside every new worktree after git makes it and before any session uses it, for the dependency links and copies a project needs
• Changed hooks: a hook is one entry under events.hooks at one of Mercury's fifteen moments (a turn, a tool call, a permission decision, a crewmate, a compaction, a session's start, end and board state, a watched file) and is a shell command, a question a model answers or a crewmate that checks; its answer can block the moment, stop the turn, add words for the model or leave you a note; /hooks lists every hook the session carries with where it came from
• Changed the prompt the model reads: about a tenth lighter on every request, each fact stated once in plain words; a tool's description says what its parameters do not already say; the git rules state only what nothing else in the prompt states
• Changed the words the model reads around its context (the date notice, the skills and MCP server headers, the deferred-tools notice, a nested instruction file's label, the notice standing in for an oversized tool result): each says its fact once
• Changed the row under a tool call that Sovereign or Flow allowed: it reads "allowed by sovereign" (or "allowed by flow") and nothing more
• Fixed a faulty hook entry (a typo, an unknown event, a field of another kind) silently matching everything or nothing: the entry is named on /health and dropped alone, and the rest of the file applies
• Fixed a run-once hook editing your settings file: it runs once in the session and stands down
• Fixed a note a hook leaves you vanishing on a resume and never reaching a daemon-hosted cockpit: it is saved with the session
• Fixed a background hook running with no clock: it is ended at its timeout like any other, and a hook that fails or times out is one line while the moment goes on
• Fixed Sovereign on Windows asking before shell commands that carry a Git Bash flag such as taskkill //PID 1234 or reg query //v: a double-slash flag is not a network share; a command that reaches another machine or a share still asks
• Fixed a session hosted by the daemon telling the model the wrong permission mode: a session opened in Sovereign, or switched with shift+tab, no longer tells the model it is in Default
• Fixed the daemon's expiry line reading "after 2m60s"
• Fixed the Test tool failing a unittest file or folder given as a path: the module is named relative to the project root, a folder is discovered the way unittest discovers it, and an import error counts once
• Fixed an OpenRouter key the provider has refused still reading as usable: /health, the Boot face's signed-in count, /logins, /model and the picker say the key was refused, with the words and the way out, until a key is re-entered or OpenRouter accepts it again
• Fixed the /logins opening sentence leaving out the last family of the list below it
• Fixed the permission card on Windows naming the folder with a backslash on its tail in a shell it was not typed in: it reads the way the box's own shell prints it
• Fixed the Computer tool's keyboard chords on macOS: cmd+q, cmd+w, cmd+n and a held chord reach the application in front
• Fixed a collapsed tool row whose call was refused showing a bare cross: the refusal's line sits under the compact row and under the opened group's member row
• Fixed mercury --mode flow opening in Sovereign on a box whose Boot Menu saves Sovereign: a typed --mode outranks the saved row, and /config names the argument as the source
• Fixed the first dropped-thinking notice after an update reading as a defect: it reads as the update, expected once, and /health reads it as info
• Fixed the preserved-thinking notice's count: one block stays out of the requests and the model re-plans without it
• Fixed the /config account row for OpenCode Zen reading unlike its neighbours
• Fixed /sessions showing a parked session as active: it reads parked, the daemon was stopped, the next prompt resumes it
• Fixed the crew rail keeping a stopped crewmate row after mercury daemon stop
• Fixed mercury daemon status naming no runners: each live worker is listed with its runner pid, its session and its state
• Fixed a crewmate's stop notice reaching the model only after its next answer: after a daemon stop the notice rides the next prompt
• Fixed a fresh daemon refusing the first chat on a local model with "model refused (unreachable:local)" while Ollama was serving: the first prompt starts the chat
• Fixed an empty reply from a local model settling the turn as completed with a stale answer: the model is asked once more
• Fixed Gemma 4's context window being sized far too small, which compacted the conversation after every tool result
• Fixed the first-run sign-in card running off the bottom of a short terminal: the provider list scrolls inside the card with "…and N more below"
• Fixed opening a row on the health page jumping the page to its end
• Fixed a quick second click on a session in the session board selecting a word instead of opening the session
• Fixed the resume recap counting only some tools: every tool the previous run used, and a ChangeSet's files count as touched
• Fixed a busy machine's daemon answers being cut off after a fixed two seconds: they are waited for as long as the daemon is working
• Fixed /context showing nothing for minutes when the provider cannot answer: the card shows at once, counting, and the chart arrives within one count's budget
• Fixed the status row saying "after unknown" while a provider is retried: it says the cause in words
• Fixed a temporary folder left in the temp directory when Mercury exits in the middle of reading a project's tree for the health certificate: the read is ended and the folder goes with it
