speckit-agent-context-updatelisted

# Update Coding Agent Context Refresh the managed Spec Kit section inside the active coding agent's context/instruction file (e.g. `CLAUDE.md`, `.github/copilot-instructions.md`, `AGENTS.md`). ## Behavior The script reads the agent-context extension config at `.specify/extensions/agent-context/agent-context-config.yml` to discover: - `context_file` — the path of the coding agent context file to manage. - `context_files` — optional project-relative paths for multiple coding agent context files. When non-empty, the script updates each listed file and the list takes precedence over `context_file`. - `context_markers.start` / `.end` — the delimiters surrounding the managed section. Defaults to `<!-- SPECKIT START -->` and `<!-- SPECKIT END -->` when the field is missing. It then creates, replaces, or appends the managed block so that the section points at the most recent plan path when one can be discovered (`specs/<feature>/plan.md`). If `context_files` and `context_file` are empty, the command reports nothing to do and exits successfully. Context file paths must stay project-relative; absolute paths, Windows drive paths, backslash separators, and `..` path segments are rejected. ## Execution - **Bash**: `.specify/extensions/agent-context/scripts/bash/update-agent-context.sh [plan_path]` - **PowerShell**: `.specify/extensions/agent-context/scripts/powershell/update-agent-context.ps1 [plan_path]` When `plan_path` is omitted, the script auto-detects the most recently modi
