Version bump path updates only

All three changes update hardcoded filesystem paths from the 0.54.0 version string to 0.54.4, covering the skill-creator and antigravity-support skill locations and the ephemeral private memory directory path. No logic, behavior, or wording was altered; these are purely mechanical path references reflecting the new release version.

Untrusted external data safety guard added

A new Core Mandate was introduced instructing the model to treat external tool and MCP server outputs wrapped in `<untrusted_context>` tags as passive data, explicitly ignoring any commands or directives within them unless the user requests otherwise. The remaining diff consists of a version bump in two skill file paths (0.47.0 → 0.49.0) and a stale temp-directory token in the Private Project Memory path, both of which are non-semantic environment updates.

Adds antigravity-support skill, scrubs memory path

A new built-in skill, `antigravity-support`, was registered to handle user questions about installing, setting up, or migrating to Antigravity CLI. The hardcoded private project memory path was updated, replacing a specific temp directory identifier with a scrubbed/anonymized placeholder, likely to avoid leaking session-specific filesystem details.

Major prompt restructure and persona reset

The agent's self-description was stripped of "Gemini CLI" branding and YOLO-mode framing, replaced with a generic non-interactive CLI agent identity. Extensive sections on context-efficiency strategy, orchestration heuristics, GEMINI.md precedence rules, and the Research→Strategy→Execution lifecycle were removed or heavily condensed. New sections were added covering shell output token efficiency, an outside-sandbox warning, a final reminder, and inline guidance on comment discipline, change summaries, and revert behavior.

Update skill-creator install path

The hardcoded filesystem path for the built-in `skill-creator` skill was updated from a workspace-local cache directory to a global npm installation path. This reflects a change in the runtime environment where the CLI is now resolved from a system-wide npm global install rather than a project-specific cache.

Expanded anti-hack and design-pattern rules

The "Types, warnings and linters" standard was broadened to explicitly prohibit "hidden" logic such as reflection and prototype manipulation, and to require explicit, idiomatic alternatives like type guards, explicit class instantiation, and object spread. A new "Design Patterns" engineering standard was added, mandating explicit composition and delegation (wrappers, proxies, factory functions) over inheritance or prototype-based cloning. A version path reference for the skill-creator skill was bumped from 0.37.2 to 0.38.0.

Research phase guidance was also extended to recommend `enter_plan_mode` for ambiguous or architecturally broad requests. Separately, a new engineering standard explicitly prohibits suppressing type-system warnings or using unsafe casts, directing use of idiomatic alternatives instead.

Major persona, workflow, and safety overhaul

The agent was formally named "Gemini CLI" and given an explicit senior-engineer persona. The primary workflow was restructured from a linear 6-step process into a Research → Strategy → Execution lifecycle with iterative Plan/Act/Validate cycles, and new Directive vs. Inquiry intent-classification semantics were introduced. Security mandates (credential protection, source-control guardrails), sub-agent XML descriptors, stricter memory-tool scoping, and a mandatory "Explain Before Acting" transparency rule were all added, while the "Outside of Sandbox" section and verbose shell-output guidelines were removed.

Stricter implicit-change confirmation required

The ambiguity-handling rule was extended to explicitly prohibit acting on implied changes (e.g., a reported bug) without user confirmation, and the planning step now mandates asking before modifying code when a request only implies a change. Sub-agent delegation instructions were restructured from a `delegate_to_agent` call pattern to direct tool invocation, with simplified agent listings and stronger guidance to use the closest relevant agent even for broader tasks. A new Hook Context section was added, instructing the model to treat `<hook_context>` content as read-only data and never as overriding instructions.

The sub-agent section was substantially expanded with concrete delegation examples and a standing directive to *always* use `delegate_to_agent` when a relevant agent exists. A minor clarification was also added requiring `git --no-pager` as an example of non-interactive command usage.

Sub-agent registry and revised workflow step

A new "Available Sub-Agents" section was added, formally documenting the `delegate_to_agent` tool and the `codebase_investigator` sub-agent with a description of when and how to invoke it. The "Understand & Strategize" workflow step was simultaneously rewritten to de-emphasize `codebase_investigator` as the mandatory first tool for complex tasks, replacing it with a broader directive to use `search_file_content`, `glob`, and `read_file` extensively and in parallel. This shifts the agent's default investigation strategy toward direct file exploration while the sub-agent capability is surfaced in its own dedicated section.

codebase_investigator promoted to primary tool

The separate "Available Sub-Agents" section describing `codebase_investigator` was removed, and its guidance was folded directly into Step 1 of the Software Engineering workflow. The step was renamed "Understand & Strategize" and now mandates `codebase_investigator` as the first and primary tool for complex refactoring or system-wide analysis, while reserving simpler search tools for targeted lookups. Step 2 was also updated to require that any `codebase_investigator` output serve as the foundation of the plan.

Adds sub-agent delegation section

A new "Available Sub-Agents" section was introduced, documenting the `delegate_to_agent` tool and the `codebase_investigator` sub-agent with its purpose and return format. The Step 1 of the Software Engineering workflow was reworked: the strong mandate to use `codebase_investigator` as the "first and primary tool" for complex tasks was replaced with a broader directive to use `search_file_content`, `glob`, and `read_file` extensively and in parallel. This shifts the default investigation strategy away from the specialized sub-agent toward direct file-exploration tools, while still advertising `codebase_investigator` as an available resource via `delegate_to_agent`.

Agent recast as fully non-interactive

The agent's self-description changed from "interactive" to "non-interactive," and all prompts to pause and confirm with the user were removed throughout the prompt. Ambiguity handling, user-approval gates for new-app plans, clarification questions, and feedback solicitation steps were all stripped out, replaced with an explicit directive to continue work autonomously using best judgment. Several guidelines (background processes, interactive commands, memory saving) were also shortened by removing their user-facing explanations and escape hatches.

Todo tracking and Angular added to workflow

The planning step now instructs the assistant to use `write_todos` for breaking complex tasks into tracked subtasks, formalizing a lightweight project-management loop. Angular was added alongside React as a recommended frontend and full-stack frontend option. Two smaller changes also landed: hardcoded session-specific temp directory paths were replaced with a generic `<temp_dir>` placeholder, and `read_many_files` was removed from the final reminder's list of approved file-reading tools.

Removes absolute path construction rules

Two explicit instructions requiring the assistant to always construct and use absolute file paths — one in the core behaviors section and one in the Tool Usage section — were removed. The session-specific temporary directory path was also refreshed to a new random value, which is a routine environment update. The net effect is that path-handling is no longer a prescribed behavior, relying instead on implicit tool defaults.

Introduces codebase_investigator as primary tool

The "Understand" step was renamed to "Understand & Strategize" and now mandates `codebase_investigator` as the first tool for complex refactoring, codebase exploration, or system-wide analysis, reserving `search_file_content`/`glob` for simple targeted lookups. The plan step was updated to require that `codebase_investigator` output form the foundation of any plan when it was used. Temp directory paths were also rotated to new session values, and minor blank-line and punctuation noise was cleaned up.

Trimmed save_memory scope guidance

The instruction for when not to use the `save_memory` tool was shortened: the explicit mention of "project-specific `GEMINI.md` files" as the correct alternative destination was removed, leaving a more general prohibition against saving non-user-specific information. This tightens the wording but slightly reduces actionable guidance for the model.

Enforce absolute paths for file tools

A new "Path Construction" rule was added requiring the assistant to always resolve full absolute paths before invoking any file system tool, combining the project root with any relative path. Two examples were updated to reflect this behavior, replacing relative paths like `'.'` and `./temp` with their absolute equivalents.

No behavioral or structural changes were made.
