Hack Through Testing

Manual invocation only: use this skill only when the developer explicitly wants this workflow.

Drive a fragile system to the end by patching forward instead of solving each issue cleanly on first contact. Keep each workaround reviewable and finish with a synthesis that guides the real implementation.

If the developer wants testing without code changes, use test-and-log instead. If the developer wants a slow, stepwise session with approval before each action, use do-interactive-test instead.

Testing Philosophy: Production-Level End-to-End, Not CI

Hack-through-testing targets production-level end-to-end paths: real data, real user workflows, real API calls, real output artifacts. It is not a CI smoke run, not a unit test harness, and not a mock-based integration check.

The distinction matters for choosing what to test:

• Do target: a full user workflow from input to final output; a real data pipeline with actual inputs; a multi-step interaction flow a real user would perform; an end-to-end scenario covering multiple system components in concert.
• Do not target: existing unit tests, existing smoke tests, isolated module tests, test suites that stub or mock external dependencies — these are already CI's job.

If the only testable surface you can identify is CI-style (unit tests, smoke scripts, mock integrations), stop and ask the developer what the real production user path or end-to-end scenario is before proceeding. For example:

I can see unit/smoke/integration tests already covered by CI. What's the real production user path you want to exercise — the end-to-end scenario, the live data workflow, or a specific user journey?

Do not invent a CI-style test run and call it hack-through-testing.

Subskills

This skill has exactly two subskills.

1. prepare Analyze the target and set up <htt-home>/ with infrastructure dirs (logs, runs, issues). If the developer explicitly requests test-case generation (e.g., "prepare test cases", "prepare for auto test", "create autotest", "set up autotest"), also create <htt-home>/autotest/ with automatic scripts and interactive guides. Primary guide: references/prepare.md

2. run Drive testing, patching forward through blockers. Uses autotest artifacts when they exist; otherwise drives testing directly from the target analysis. Operates in-place (default) or in a disposable snapshot worktree. Primary guide: references/run.md

Subskill Selection

• "prepare", "bootstrap", "plan", "set up" → prepare (infrastructure only, no autotest)
• "prepare test cases", "prepare for auto test", "create autotest", "set up autotest", "create test cases" → prepare with autotest generation
• "run", "test", "execute", "drive", "patch forward" → run only
• If the developer asks for both, or does not specify → run prepare then run
• If autotest artifacts already exist and the developer wants to go straight to driving → run only

Shared Defaults

Unless the developer says otherwise, use these defaults across both subskills:

• Target: if the developer does not point to a specific file, directory, command, or entrypoint — or says "repo root", "workspace root", "here", "current dir" — use the agent's current working directory as the target
• Topic slug: derive from the target; normalize to hyphen-case; keep stable for the whole session
• HTT home (htt-home): <repo-root>/.agent-automation/hacktest/<topic-slug> unless the developer explicitly sets htt-home=<dir>
• Log root: <htt-home>/logs
• Runs root: <htt-home>/runs
• Session log: <log-root>/<ts>.md
• Issue notes: <log-root>/issues/<ts>-<what>.md — one file per underlying issue; append later fixes to the same note rather than creating a new one
• Run artifacts: <runs-root>/<run-ts>/ — always copy generated artifacts here so they survive session cleanup
• Issue IDs: HT-01, HT-02, ...
• Commit message format (worktree mode) / Stash message format (in-place mode): hack-through: <issue-id> <short workaround>
• Stopping rule: first successful end-to-end run, 10 distinct issues, or 90 minutes — whichever comes first
• Data realism: use real data, real inputs, and live API calls wherever safe. Synthetic or stubbed inputs are a last resort. Never default to a CI-style smoke run unless the developer explicitly asks for one.
• Path references in logs: always use repo-relative paths plus commit SHAs. Logs must remain useful after the session ends.

If this skill creates .agent-automation/hacktest/, add it to .gitignore. If .gitignore already has commented .agent-automation/hacktest entries, do not auto-add the rule.

Guardrails

• Never lose or overwrite the developer's current uncommitted state. In in-place mode, always stash before starting and record the stash ref. Never drop the initial stash until the developer explicitly requests cleanup.
• In worktree mode, never perform hack-through edits in the original checkout after the snapshot worktree exists.
• Never commit helper-managed log or autotest artifacts to htt-branch (worktree mode) or mix them into stash snapshots (in-place mode).
• Never present a temporary workaround as the final fix.
• Never keep going silently after a workaround invalidates trust in later observations; log the caveat.
• In worktree mode, never merge the throwaway branch into real work.
• Never reduce interactive guides (case-<id>.md) to wrappers that just say "run the automatic script"; they must be independent step-by-step procedures.
• Never skip the prepare subskill silently when the run subskill needs htt-home infrastructure and it is missing.

Example Prompts

• Use $hack-through-testing on this CLI and keep patching forward until the happy path finishes.
• Use $hack-through-testing to prepare for the demo under scripts/demo/foo. (infrastructure only)
• Use $hack-through-testing to prepare autotest cases for the demo under scripts/demo/foo. (with autotest generation)
• Use $hack-through-testing in run mode with interactive driving — I want to watch each step.
• Use $hack-through-testing with a worktree so my checkout stays clean.
• Use $hack-through-testing to exercise the full build-then-launch sequence — build a brain, start a session, send a prompt, stop — and patch through every failure.
• Use $hack-through-testing, but pause if the only workaround would change the protocol or persistent data format.
• Use $hack-through-testing with htt-home=/tmp/my-htt-home so the whole session state is easy to revisit later.
• Use $hack-through-testing to prepare test cases, then run them automatically in a shadow repo, stop after 8 blockers.
