The Agent Skills Directory

[COMMAND_EXECUTION]: The skill executes multiple shell commands to manage the testing environment, including git worktree add, git diff, timeout, and git worktree remove. It also executes a local shell script located at ../tester/scripts/check-locked-tests.sh.
[EXTERNAL_DOWNLOADS]: The skill uses npx stryker run in references/mutation.md, which may download the Stryker mutation testing tool from the npm registry if it is not present locally.
[DYNAMIC_EXECUTION]: In the 'Without Stryker' section of references/mutation.md, the agent is instructed to manually modify source code ('Hand-place mutants') by inverting conditions, dropping calls, or returning constants, and subsequently executing the test suite against these modifications.
[INDIRECT_PROMPT_INJECTION]: The skill processes untrusted external data from git diffs and ticket descriptions.
Ingestion points: Data enters via git diff output and the ticket ref argument.
Boundary markers: No explicit delimiters or instructions to ignore embedded commands within the diff or ticket body are provided.
Capability inventory: The skill has the ability to execute shell commands, run external packages, and modify/execute local code.
Sanitization: There is no evidence of sanitization or validation of the content within the diff or ticket description before processing.
