"description": "Execute a shell command in the terminal within a persistent shell session.\n\n\n### Command Execution\n* One command at a time: You can only execute one shell command at a time.\n If you need to run multiple commands sequentially, use `&&` or `;`.\n* Persistent session: Environment variables, virtual environments, and\n working directory changes persist across commands.\n* Soft timeout: Commands pause for confirmation after 10 seconds without\n new output unless you provide a longer `timeout`.\n* Shell options: Do NOT use `set -e`, `set -eu`, or `set -euo pipefail`.\n The runtime may not support them reliably.\n\n### Long-running Commands\n* For commands that may run indefinitely, run them in the background and\n redirect output to a file, e.g. `python3 app.py > server.log 2>&1 &`.\n* For long-running commands, set the `timeout` parameter accordingly.\n* If a command returns exit code `-1`, it hit the soft timeout and is\n still running. With `is_input=true`, you can:\n - Send empty `command` to retrieve additional logs\n - Send text to STDIN of the running process\n - Send control commands like `C-c`, `C-d`, or `C-z`\n - Send navigation keys like `UP`, `DOWN`, `LEFT`, `RIGHT`, `TAB`,\n `ESC`, `BS`, `HOME`, `END`, `PGUP`, and `PGDN`\n - Send any `C-<letter>` Ctrl sequence such as `C-a`, `C-e`, or `C-l`\n\n### Best Practices\n* Verify a parent directory exists before creating files or directories.\n* Prefer absolute paths and avoid excessive use of `cd`.\n\n### Output Handling\n* Large output may be truncated before being returned.\n\n### Terminal Reset\n* Set `reset=true` to create a fresh terminal session if the current one\n becomes unresponsive.\n* Resetting the terminal clears environment variables, working directory\n changes, and running processes.",

"description": "Custom editing tool for viewing, creating and editing files in plain-text format\n* State is persistent across command calls and discussions with the user\n* If `path` is a text file, `view` displays the result of applying `cat -n`. If `path` is a directory, `view` lists non-hidden files and directories up to 2 levels deep\n* The `create` command cannot be used if the specified `path` already exists as a file\n* If a `command` generates a long output, it will be truncated and marked with `<response clipped>`\n* The `undo_edit` command will revert the last edit made to the file at `path`\n* This tool can be used for creating and editing files in plain-text format.\n\n\nBefore using this tool:\n1. Use the view tool to understand the file's contents and context\n2. Verify the directory path is correct (only applicable when creating new files):\n - Use the view tool to verify the parent directory exists and is the correct location\n\nWhen making edits:\n - Ensure the edit results in idiomatic, correct code\n - Do not leave the code in a broken state\n - Always use absolute file paths (starting with /)\n\nCRITICAL REQUIREMENTS FOR USING THIS TOOL:\n\n1. EXACT MATCHING: The `old_str` parameter must match EXACTLY one or more consecutive lines from the file, including all whitespace and indentation. The tool will fail if `old_str` matches multiple locations or doesn't match exactly with the file content.\n\n2. UNIQUENESS: The `old_str` must uniquely identify a single instance in the file:\n - Include sufficient context before and after the change point (3-5 lines recommended)\n - If not unique, the replacement will not be performed\n\n3. REPLACEMENT: The `new_str` parameter should contain the edited lines that replace the `old_str`. Both strings must be different.\n\nRemember: when making multiple file edits in a row to the same file, you should prefer to send all edits in a single message with multiple calls to this tool, rather than multiple messages with a single call each.\n\n\nYour current working directory is: /Users/instructor/Code/odsc-runs/session-20261017-163134-615d65/w5-goal\nWhen exploring project structure, start with this directory instead of the root filesystem.",

**Root cause:** In `src/slugify.py`, the character-stripping regex `[^\w\s-]` removed dots along with other punctuation, so `"api.v1"` became `"apiv1"`.
**Fix (src/slugify.py):** Added `.` to the allowed set → `[^\w\s.-]`. Dots now survive, while all prior stripping behavior is unchanged.
**Tests (tests/test_slugify.py):** All 5 existing tests were preserved untouched; I added one regression test `test_dots_are_preserved` asserting `slugify("api.v1 endpoint") == "api.v1-endpoint"`.
**Verification (after the latest edit):**
```
