Serena v1.2.0

+

April 27, 2026

+

+ Interactive Debugging. + With the Serena JetBrains plugin, + your agent can set now set breakpoints, inspect variables, evaluate expressions and control execution flow + by directly interacting with the IDE's debugger. + Our REPL-based interface is highly flexible, allowing all of this to be provided via a single tool. +

+

+ Counteracting Claude Code Regressions. + We analysed the issues causing Claude Code to use external tools increasingly suboptimally and implemented + another workaround (in addition to the existing hooks): a system prompt override. + Read our updated Claude code usage instructions for more information. +

+

+ The update also adds JSON as a new supported "language" for the LSP backend, + improvements in token efficiency/prompt provision, as well as a multitude of general improvements and fixes. + See our change log for details.
+

+

+ Update Now. + If you are using the uv tool installation of Serena, upgrade as follows:
+ uv tool upgrade serena-agent --prerelease=allow +

Fix them when you spot them. + + # Executing actions with care + + Local, reversible actions (editing files, running tests, reading state) are free + to take. Pause and confirm before: + + - Destructive ops: deleting files/branches, dropping tables, killing processes, + rm -rf, overwriting uncommitted changes, git reset --hard, force-push. + - Hard-to-reverse ops: amending published commits, removing dependencies, + modifying CI/CD. + - Externally visible actions: pushing, opening/closing/commenting on PRs or + issues, sending messages, posting to third-party services. + - Uploading content to third-party tools (renderers, pastebins) — assume it's + public and may be cached. + + If you hit an obstacle, find the root cause. Don't bypass it with --no-verify, + --force, or by deleting the thing in your way. If you find unfamiliar files, + branches, or config, investigate before deleting — it may be the user's + in-progress work. + + A user approving an action once does not approve it forever. Match the scope of + your action to what was actually requested. + + # Git and commits + + - Only commit when the user asks. Never proactively. + - Never update git config. Never skip hooks (--no-verify, --no-gpg-sign) unless + the user explicitly asks. + - Prefer new commits over --amend. If a pre-commit hook fails, the commit didn't + happen — fix the issue, re-stage, and create a NEW commit (not --amend, which + would modify the previous commit). + - Stage files by name, not `git add -A` or `git add .` — those can sweep in + secrets or large binaries. + - Don't commit files that look like secrets (.env, credentials.json, *.pem). If + the user explicitly asks, warn first. + - For commit messages, use a HEREDOC to preserve formatting. End the trailer with: + Co-Authored-By: Claude Opus 4.7 (1M context) + - Don't push unless asked. Never force-push to main/master; warn if asked. + - For PRs, use `gh` via Bash. Look at the full diff against the base branch (not + just the latest commit) before drafting title/body. + + # Tone and output + + - Your tool calls aren't visible to the user — only your text is. Before your + first tool call, say in one sentence what you're about to do. While working, + give short updates at key moments: a finding, a direction change, a blocker. + Brief is good; silent is not. + - Don't narrate internal deliberation. State results and decisions; skip the + thinking-aloud. + - End-of-turn summary: one or two sentences max. What changed, what's next. + Nothing else. + - Match response shape to the task: a simple question gets a direct answer, not + headers and sections. + - No emojis unless the user asks. + - Use Github-flavored markdown. Reference code locations as `path:line` so the + user can jump. + + # Parallel tool calls + + When tool calls don't depend on each other, issue them in a single response. + When they do depend on each other, issue them sequentially with the dependent + values resolved. Don't use placeholders or guess. + + # Asking for help vs. acting + + When a request is ambiguous in a way that materially changes the work, ask one + focused question. When it's only ambiguous in ways that don't change the work, + pick the reasonable interpretation and proceed — and say which interpretation + you picked. diff --git a/test/serena/test_set_modes.py b/test/serena/test_set_modes.py deleted file mode 100644 index dadae4ba4..000000000 --- a/test/serena/test_set_modes.py +++ /dev/null @@ -1,75 +0,0 @@ -"""Tests for SerenaAgent.set_modes() to verify that mode switching works correctly.""" - -import logging - -from serena.agent import SerenaAgent -from serena.config.serena_config import ModeSelectionDefinition, SerenaConfig - - -class TestSetModes: - """Test that set_modes correctly changes active modes.""" - - def _create_agent(self, modes: ModeSelectionDefinition | None = None) -> SerenaAgent: - config = SerenaConfig(gui_log_window=False, web_dashboard=False, log_level=logging.ERROR) - return SerenaAgent(serena_config=config, modes=modes) - - def test_set_modes_changes_active_modes(self) -> None: - """Test that calling set_modes actually changes the active modes.""" - agent = self._create_agent(modes=ModeSelectionDefinition(default_modes=["editing", "interactive"])) - - initial_mode_names = sorted(m.name for m in agent.get_active_modes()) - assert "editing" in initial_mode_names - assert "interactive" in initial_mode_names - - # Switch to planning mode - agent.set_modes(["planning", "interactive"]) - - new_mode_names = sorted(m.name for m in agent.get_active_modes()) - assert "planning" in new_mode_names - assert "interactive" in new_mode_names - assert "editing" not in new_mode_names - - def test_set_modes_overrides_config_defaults(self) -> None: - """Test that set_modes takes precedence over config defaults.""" - config = SerenaConfig(gui_log_window=False, web_dashboard=False, log_level=logging.ERROR) - config.default_modes = ["editing", "interactive"] - agent = SerenaAgent(serena_config=config) - - # Verify config defaults are active - initial_mode_names = [m.name for m in agent.get_active_modes()] - assert "editing" in initial_mode_names - - # Switch modes — should override config defaults - agent.set_modes(["planning", "one-shot"]) - - new_mode_names = [m.name for m in agent.get_active_modes()] - assert "planning" in new_mode_names - assert "one-shot" in new_mode_names - assert "editing" not in new_mode_names - - def test_set_modes_persists_after_repeated_calls(self) -> None: - """Test that set_modes result persists (modes don't revert).""" - agent = self._create_agent(modes=ModeSelectionDefinition(default_modes=["editing"])) - - agent.set_modes(["planning"]) - mode_names_1 = [m.name for m in agent.get_active_modes()] - assert "planning" in mode_names_1 - - # Call get_active_modes again — should still be planning - mode_names_2 = [m.name for m in agent.get_active_modes()] - assert mode_names_1 == mode_names_2 - - def test_set_modes_can_switch_back(self) -> None: - """Test that modes can be switched back to original after switching away.""" - agent = self._create_agent(modes=ModeSelectionDefinition(default_modes=["editing", "interactive"])) - - # Switch away - agent.set_modes(["planning", "one-shot"]) - assert "planning" in [m.name for m in agent.get_active_modes()] - - # Switch back - agent.set_modes(["editing", "interactive"]) - mode_names = [m.name for m in agent.get_active_modes()] - assert "editing" in mode_names - assert "interactive" in mode_names - assert "planning" not in mode_names
