      "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: /private/tmp/odsc-workshop6-v2/reservation-team-t1\nWhen exploring project structure, start with this directory instead of the root filesystem.",

     1	Prepared candidate: defects intentionally seeded, not a historical agent failure.
     2	Implement Inventory(stock), reserve(request_id, lines), cancel(request_id), snapshot(). stock is a dict of SKU to nonnegative integer. lines is a list of (SKU, positive integer quantity). Repeated SKU quantities add. reserve returns True if all quantities are available and deducts them atomically; otherwise False with no mutation. Unknown SKU or nonpositive quantity returns False. Empty lines succeeds. Successful request IDs are idempotent: an exact replay (same aggregate quantities, order irrelevant) returns True without deduction; a different payload for an active ID returns False. Failed requests are not remembered. cancel returns True exactly once for an active successful request and restores its stock; absent or already cancelled IDs return False. A cancelled ID may be reused. snapshot returns a detached dict. Constructor must copy input. No concurrency. Only inventory.py and test_inventory.py may change.

README is the contract (line 2). inventory.py tested with fresh scripts in /tmp (deleted after; repo untouched, smoke test passes). Adversarial probes found **10 failures** in `reserve`/`cancel`/`snapshot`/`__init__`:

| Input | Expected (contract clause) | Observed |
|---|---|---|
| `Inventory({'a':5})`, mutate source `{'a':0}` | snapshot `{'a':5}` (ctor must copy input) | `{'a':0}` — stored by reference |
| `reserve('rx',[('a',4),('b',2)])` on `{a:5,b:1}` | `False`, then `{a:5,b:1}` (atomic: all-or-nothing) | `False` then `{a:1,b:1}` — partial deduction |
| `reserve('ry',[('a',1),('z',1)])` on `{a:1}` | `False`, no mutation (unknown SKU) | `False`, `{a:0}` — deducted a before hitting unknown SKU |
| `reserve('d0',[('a',0)])` / `('a',-1)` | `False` (nonpositive qty) | `True` |
| `reserve('rx2',[('a',2),('a',3)])` on `{a:5}` then `cancel` | cancel restores `{'a':5}` (repeated SKUs add) | snapshot before `{'a':0}`; after cancel `{'a':3}` — second line overwrote deduction record |
| `reserve('pe',[('a',1)])` then `reserve('pe',[('c',1)])` | `False` (different payload for active ID) | `True` — extra `c` deducted |
| `cancel(p)` twice on `{a:5,b:5}` reserve 2a,3b | 2nd cancel `False` (exactly once) | `True`; snapshot over-restored to `{a:7,b:8}` — record kept after cancel |
| cancelled-ID reuse: reserve `('pu',[('a',4)])` after cancelling a 2a reserve | `True`, snapshot `{a:1}` | `True`, snapshot `{a:5}` (old lines still applied at cancel) |
| `snapshot()` mutate returned dict | internal unchanged (detached) | internal mutated to `{'a':999}` |

Passing: empty-line reserve, exact replay idempotency, order/aggregate-equal replay, cancel-absent→False, insufficient-qty failure, positive basic reserve/cancel.
