It can explain and modify code, run commands, create documentation, and work with specialized agents or skills. Bob spans the IDE and shell, but that reach also gives it material workspace access. Its output, commands, and external integrations require the same review and security discipline as human-authored changes.\r\n\r\n
\r\n \"Development\r\n
\r\n\r\n## What is IBM Bob for?\r\n\r\nBob targets developers and larger engineering organizations looking beyond autocomplete. It addresses work across the software development lifecycle: understanding existing code, planning changes, producing implementations, adding tests and documentation, and preparing modernization work. IBM also positions specialized packages for Java, IBM i, and IBM Z.\r\n\r\nThe product is most plausible in heterogeneous enterprise codebases where editor work, terminal steps, and organization-specific knowledge meet. A smaller assistant may be enough for a narrow code question. Bob does not replace architecture ownership, code review, security scanning, or business acceptance.\r\n\r\n## How do modes, tools, skills, and subagents work together?\r\n\r\nModes separate working intent. Ask explains a codebase, Plan structures a change before implementation, and Agent can edit files and execute development work. Bob includes read and write tools, symbol and code search, command execution, and predefined workflows. Skills load curated domain instructions, while MCP connects local or remote tools and services.\r\n\r\nFor larger tasks, Bob can start focused subagents with independent context. Its documentation says the user approves each spawn. A subagent returns a summary to the main context; its separate context window is not a separate filesystem or security sandbox. Bob Shell brings agent capabilities to interactive terminal and automation flows, expanding the potential impact of a task.\r\n\r\n## What is a sensible working process?\r\n\r\nStart from a clean branch and state success criteria, permitted paths, and verification commands. Explore a new codebase in Ask or Plan mode first. A useful request names affected components, non-goals, expected behavior, and existing tests. Only after reviewing the plan should the agent receive a small reversible implementation task.\r\n\r\nReview the diff, executed commands, and test results separately. Do not let Bob bypass an unexplained error through broad configuration changes. For modernization, pilot a representative application slice with measurable behavior parity before extending a premium workflow to more modules. Commit, pull request, and deployment should remain separate approval gates.\r\n\r\n## How does Bob fit a team and pipeline?\r\n\r\nIn the editor, Bob works with the open workspace. Bob Shell exposes similar capabilities in a terminal and can participate in scripts or CI. MCP servers add access to external APIs, knowledge, and enterprise systems. Enterprise capabilities include central team administration, roles, allocation of usage entitlements, and contribution analytics through Bobalytics.\r\n\r\nEvery integration needs an owner and attributable permissions. API keys used for automation should be managed individually and rotated. MCP activity must remain attributable to a user or run. Updates to Bob, skills, and connected servers belong in dependency governance because they can alter behavior and available tools.\r\n\r\n## How should result quality be measured?\r\n\r\nUse real tasks backed by tests: reproduce and fix a bug, extend a small API, document legacy logic, or migrate one module. Score functional correctness, test coverage, unnecessary diff size, security regressions, and reviewer time. A command completing successfully does not prove that the resulting change is correct.\r\n\r\nModernization also requires reproducible builds, behavior comparison, dependency risk, and maintainability by the team. Bobalytics can show usage and contributions, but productivity should not be inferred from generated lines or session counts. The useful outcome is accepted, tested software with less follow-up work.\r\n\r\n## What are the security and privacy boundaries?\r\n\r\nIBM's security guidance recommends `.bobignore` to exclude workspace files. It is not a system sandbox and does not protect anything outside Bob's tools. Secrets should also live in a secret manager and be excluded through `.gitignore`; they do not belong in prompts or accessible examples. Broad auto-approval for file changes, commands, and MCP materially increases risk.\r\n\r\nRemote MCP servers require authentication, encryption, least privilege, and audit logs. Unknown repositories, build scripts, and documentation can contain manipulative instructions. Sensitive work therefore benefits from dedicated workspaces, narrow tokens, and human review of every high-impact action. Enterprise buyers should also establish contractual terms for data processing, retention, and model use.\r\n\r\n## What does Bob cost to operate?\r\n\r\nBob offers trial and paid access, with plans and entitlements expressed through Bobcoins. Enterprise customers receive central controls and support, while specialized modernization packages may be priced separately. IBM's current pricing page notes that prices vary by country and may exclude taxes, duties, or availability constraints.\r\n\r\nTotal cost includes onboarding, reviewer time, premium packages, external MCP services, CI resources, and rework. Track cost per accepted change, not consumption per user alone. Entitlement limits, separated pilot groups, and a clear stop condition keep adoption proportional to demonstrated value.\r\n\r\n## Editorial Assessment\r\n\r\nIBM Bob is a credible option for organizations with large or legacy codebases that want agentic editor and shell work combined with modernization expertise and central management. It provides the most value where tests, review ownership, and safe tool boundaries already exist. A focused coding assistant may be simpler for individual developers, compact modern projects, or strictly isolated code analysis.\r\n\r\n## Alternatives\r\n\r\n- [GitHub Copilot](/en/tools/github-copilot/): A widely adopted IDE and GitHub assistant when specialized modernization packages matter less.\r\n- [OpenAI Codex](/en/tools/openai-codex/): Suited to delegated repository tasks and cloud or local coding workflows without an IBM-specific focus.\r\n- [Cursor](/en/tools/cursor/): An AI-centered code editor for interactive development with less emphasis on enterprise modernization packages.\r\n- [Microsoft Agent Framework](/en/tools/microsoft-agent-framework/): An open-source base for teams building their own agent runtime rather than adopting a finished coding product.\r\n\r\n## FAQ\r\n\r\n**Can IBM Bob edit files and run commands?**\r\n\r\nYes. Bob includes tools for file reading and writing plus command execution. Parameters are shown for review unless auto-approve bypasses that confirmation.\r\n\r\n**How do Ask, Plan, and Agent differ?**\r\n\r\nAsk answers questions about the codebase, Plan proposes an approach, and Agent carries out changes. The separation supports deliberate analysis before implementation.\r\n\r\n**Are subagents automatically security-isolated?**\r\n\r\nNo. They use a separate context and require spawn approval, but they are not a system sandbox. Their tools and returned results still need review.\r\n\r\n**Does `.bobignore` protect every secret?**\r\n\r\nNo. It limits Bob tools inside the current workspace. It does not replace system isolation, secret management, narrow credentials, or secure MCP configuration." } }
