Changed

• Version bumped to 0.1.0 (minor release for new feature)

[0.0.22] - 2025-11-07

• Support for VS Code/Copilot agents, and moving away from prompts to proper agents with hand-offs.
• Move to use AGENTS.md for Copilot workloads, since it's already supported out-of-the-box.
• Adds support for the version command. (#486)
• Fixes potential bug with the create-new-feature.ps1 script that ignores existing feature branches when determining next feature number (#975)
• Add graceful fallback and logging for GitHub API rate-limiting during template fetch (#970)

[0.0.21] - 2025-10-21

• Fixes #975 (thank you @fgalarraga).
• Adds support for Amp CLI.
• Adds support for VS Code hand-offs and moves prompts to be full-fledged chat modes.
• Adds support for version command (addresses #811 and #486, thank you @mcasalaina and @dentity007).
• Adds support for rendering the rate limit errors from the CLI when encountered (#970, thank you @psmman).

[0.0.20] - 2025-10-14

Added

• Intelligent Branch Naming: create-new-feature scripts now support --short-name parameter for custom branch names
  • When --short-name provided: Uses the custom name directly (cleaned and formatted)
  • When omitted: Automatically generates meaningful names using stop word filtering and length-based filtering
  • Filters out common stop words (I, want, to, the, for, etc.)
  • Removes words shorter than 3 characters (unless they're uppercase acronyms)
  • Takes 3-4 most meaningful words from the description
  • Enforces GitHub's 244-byte branch name limit with automatic truncation and warnings
  • Examples:
    • "I want to create user authentication" → 001-create-user-authentication
    • "Implement OAuth2 integration for API" → 001-implement-oauth2-integration-api
    • "Fix payment processing bug" → 001-fix-payment-processing
    • Very long descriptions are automatically truncated at word boundaries to stay within limits
  • Designed for AI agents to provide semantic short names while maintaining standalone usability

Changed

• Enhanced help documentation for create-new-feature.sh and create-new-feature.ps1 scripts with examples
• Branch names now validated against GitHub's 244-byte limit with automatic truncation if needed

[0.0.19] - 2025-10-10

Added

• Support for CodeBuddy (thank you to @lispking for the contribution).
• You can now see Git-sourced errors in the Specify CLI.

Changed

• Fixed the path to the constitution in plan.md (thank you to @lyzno1 for spotting).
• Fixed backslash escapes in generated TOML files for Gemini (thank you to @hsin19 for the contribution).
• Implementation command now ensures that the correct ignore files are added (thank you to @sigent-amazon for the contribution).

[0.0.18] - 2025-10-06

Added

• Support for using . as a shorthand for current directory in specify init . command, equivalent to --here flag but more intuitive for users.
• Use the /speckit. command prefix to easily discover Spec Kit-related commands.
• Refactor the prompts and templates to simplify their capabilities and how they are tracked. No more polluting things with tests when they are not needed.
• Ensure that tasks are created per user story (simplifies testing and validation).
• Add support for Visual Studio Code prompt shortcuts and automatic script execution.

Changed

• All command files now prefixed with speckit. (e.g., speckit.specify.md, speckit.plan.md) for better discoverability and differentiation in IDE/CLI command palettes and file explorers

[0.0.17] - 2025-09-22

Added

• New /clarify command template to surface up to 5 targeted clarification questions for an existing spec and persist answers into a Clarifications section in the spec.
• New /analyze command template providing a non-destructive cross-artifact discrepancy and alignment report (spec, clarifications, plan, tasks, constitution) inserted after /tasks and before /implement.
  • Note: Constitution rules are explicitly treated as non-negotiable; any conflict is a CRITICAL finding requiring artifact remediation, not weakening of principles.

[0.0.16] - 2025-09-22

Added

• --force flag for init command to bypass confirmation when using --here in a non-empty directory and proceed with merging/overwriting files.

Added

• Support for Kilo Code. Thank you @shahrukhkhan489 with #394.

• Agent folder security notice displayed after project provisioning completion, warning users that some agents may store credentials or auth tokens in their agent folders and recommending adding relevant folders to .gitignore to prevent accidental credential leakage.

Changed

• Warning displayed to ensure that folks are aware that they might need to add their agent folder to .gitignore.
• Cleaned up the check command output.

[0.0.12] - 2025-09-21

Changed

[0.0.11] - 2025-09-20

Added

• Codex CLI support (thank you @honjo-hiroaki-gtt for the contribution in #14)
