# Scripts

Run scripts from the repository root. PowerShell and Bash commands have equivalent behavior unless noted otherwise.

## Layout

| Directory | Purpose |
| --- | --- |
| `scripts/commands/` | User-facing build, installation, maintenance, and local utility commands. |
| `scripts/checks/` | Standalone configuration validation. |
| `scripts/tests/` | Repository verification scripts. |
| `scripts/lib/` | Internal helpers used by commands; do not invoke them directly. |

## Commands

| Script | Purpose |
| --- | --- |
| `commands/build.ps1`, `commands/build.sh` | Generate four client packages in `generated/` from the shared skill catalog. |
| `commands/check-capabilities.ps1`, `commands/check-capabilities.sh` | Check required tools and versions. |
| `commands/install.ps1`, `commands/install.sh` | Install a selected client configuration. |
| `commands/update.ps1`, `commands/update.sh` | Update an existing installation; Quick reuses saved choices. |
| `commands/uninstall.ps1`, `commands/uninstall.sh` | Remove setup-owned configuration and extensions. |
| `commands/doctor.ps1`, `commands/doctor.sh` | Check generated output and installed configuration. |
| `commands/prompt-budget.ps1`, `commands/prompt-budget.sh` | Track permanent context, skill metadata, the rule catalog, and agent metadata; warn above 10,000 permanent-context tokens, fail when any token estimate exceeds its baseline by 10%, or permanent context exceeds 15,000 tokens. |
| `commands/context-report.ps1`, `commands/context-report.sh` | Report the context installed Claude and Codex actually load, from Claude `/context`, `/skill-doctor`, and its init event, and Codex `debug prompt-input`: categories, active plugins, listed skills, installed skills missing from the listing, and skills listed without description context. `--check` fails on missing or description-less skills. No model request is made. |
| `commands/benchmark.ps1`, `commands/benchmark.sh` | Run the Python, C#/ASP.NET, and TypeScript tasks under `scripts/benchmarks/tasks/` with and without the installed setup. Both arms of a client use one pinned model and reasoning effort; a preflight records what each arm actually loads in `provenance.json` and stops when the arms are not comparable; `--arms setup setup-no-search --tasks 11-* 12-* 13-* --warm-index` compares Claude with and without semantic search on concept-search tasks in a large generated repository, and compare pass rate, rework turns, duration, tokens, tool calls, cost, and workflow checks per task category (`category` in `task.json`: small change, larger implementation, search) (no planning ceremony for a small change, targeted verification for a bugfix, bounded delegation for a larger change). Starts real model sessions; use `--dry-run` to list runs. The Codex baseline needs one `codex login` with `CODEX_HOME` set to `--codex-baseline-home`. |
| `commands/repository-context.ps1`, `commands/repository-context.sh` | Refresh the local repository-context cache. |
| `commands/session-state.ps1`, `commands/session-state.sh` | Read or update the local agent session state. |
| `commands/telemetry.ps1`, `commands/telemetry.sh` | Append a local telemetry event. |
| `commands/add-instruction.ps1`, `commands/add-instruction.sh` | Append a client-specific user instruction outside managed configuration. |
| `commands/remove-instruction.ps1`, `commands/remove-instruction.sh` | Remove the last exact matching instruction block for a selected client. |
| `commands/add-credentials.ps1`, `commands/add-credentials.sh` | Store a client-scoped tool credential in the operating-system credential store. |
| `commands/remove-credentials.ps1`, `commands/remove-credentials.sh` | Delete a selected client-scoped credential from the operating-system credential store. |

Prompt KPIs estimate tokens as UTF-8 bytes divided by four, using the larger shell package per client. Skill metadata counts `SKILL.md` frontmatter outside rule skills; the rule catalog counts all generated rule entry files but excludes references, so it measures the available catalog size rather than rules loaded in a typical session; agent metadata counts frontmatter for Claude and `name`/`description` for Codex. All metrics fail CI above baseline +10%; permanent context also warns above 10,000 tokens and fails above 15,000 tokens. The baseline covers the retained skill catalog. Project-specific instructions, external plugin prompt bodies, and live MCP/tool schemas are not measured.

Custom instructions are read before generated rules, skills, and plugins. They remain under `~/.my-ai-configuration/instructions/`, so installation and update scripts never manage or reset them.
To undo an added instruction, pass the same text to `remove-instruction` with `-Client`/`--client` and `-Instruction`/`--instruction`. It removes the last exact matching block per selected client and preserves other text. A missing match leaves the file unchanged.

Credential commands currently require PowerShell and Windows Credential Manager, including their Bash wrappers. Use `~/.my-ai-configuration/bin/with-credential.ps1` or `.sh` to run a tool with a stored key available only in that child process. The key must be a valid environment-variable name; its value is never written to configuration.
Use `remove-credentials` with `-Client`/`--client` and `-Key`/`--key` to delete only that credential. The shared `with-credential` helpers remain installed for other keys.

The A/B benchmark measures whole sessions. Auto selection of local QMD search uses `shared/qmd/qmd-benchmark.mjs`, run through `scripts/lib/qmd.py`. It measures median search latency and embedding throughput on GPU, then CPU, and is not an end-to-end performance estimate.

## Checks and tests

Gitea Actions runs the repository checks from `.gitea/workflows/ci.yml`.

| Script | Purpose |
| --- | --- |
| `checks/validate-config.py` | Validate generated Codex TOML and Claude JSON. |
| `tests/test-build-validation.ps1`, `tests/test-build-validation.sh` | Validate build failures and generated output. |
| `tests/test-capabilities.ps1` | Guard PowerShell capability detection. |
| `tests/test-install-guards.ps1`, `tests/test-install-guards.sh` | Validate install and update guard conditions. |
| `tests/test-config-effects.py` | Check that generated limits and permissions take effect: Codex keeps the V1 multi-agent implementation that honors `agents.max_depth`; with `AI_CONFIG_LIVE_TESTS=1`, short Haiku sessions confirm that Claude withholds the Agent tool from subagents, refuses subagents above the concurrency limit, and blocks `git reset --hard` in every shell tool. |
| `tests/test-client-smoke.py` | Install a package into a temporary home with foreign settings and ask the installed Claude and Codex CLIs which skills, agents, and hooks they discover, without completing a model request. Skips a client whose CLI is unavailable unless `AI_CONFIG_REQUIRE_CLIENTS=1`, which the CI `client-smoke` job sets. |
| `tests/test-install-options.py` | Validate interactive option handling and generated manifest changes. |
| `tests/test-managed-extensions.py` | Validate plugin, skill, and CLI ownership handling. |
| `tests/test-managed-install.ps1`, `tests/test-managed-install.sh` | Validate managed-file synchronization and backups. |
| `tests/test-plugin-selection.ps1`, `tests/test-plugin-selection.sh` | Validate plugin selection. |
| `tests/test-prompt-budget.py` | Validate prompt budget threshold evaluation. |
| `tests/test-prompt-inventory.py` | Validate prompt inventory collection. |
| `tests/test-quick-update.py` | Validate saved Quickupdate choices. |
| `tests/test-remove-customizations.py` | Validate targeted instruction and credential removal without accessing the real credential store. |
| `tests/test-quick-update.ps1`, `tests/test-quick-update.sh` | Run the Quickupdate test through the relevant shell. |
| `tests/test-qmd-*.mjs` | Validate the QMD library, search, daemon, warm-up, and benchmark scripts. |
| `tests/test-qmd-setup.py` | Validate QMD installation, migration, and removal. |
| `tests/test-session-state.py` | Validate session-state helpers. |
| `tests/test-shell-packages.ps1`, `tests/test-shell-packages.sh` | Validate generated package contents and client settings. |
| `tests/test-runtime-status.ps1`, `tests/test-runtime-status.sh` | Validate build summaries and status-line output. |
| `tests/test-install-selections.ps1`, `tests/test-install-selections.sh` | Validate dry-run shell and client selections. |
| `tests/test-command-summaries.ps1`, `tests/test-command-summaries.sh` | Validate doctor, install, and update summary output. |
| `tests/test-telemetry.py` | Validate telemetry output. |
| `tests/test-user-customizations.py` | Validate user instruction overlays and credential helpers. |
