Every +command name, tool name, file name, field, reason and vocabulary value on this +page can still change in the agent-experience (AX) compatibility review. It is +not a stable interface promise. + +The task catalog lets an agent discover a small set of reviewed recipes for +scripts that already exist in a repository: what to run (exact argv and +Compose service), with which env scope, what it needs, what it changes, how +to check it and how to clean up. Discovery is read-only. **The catalog has no +execution path.** Running a recipe stays under WU26's execution policy, which +is not implemented here. + +## Decisions + +1. **Source of truth: `.hack/tasks.json`.** Recipes live in one checked-in + file in the project directory, reviewed through normal code review. It is + a separate file, not a `hack.config.json` key, so the published config + schema and the WU31 config generation stay unchanged, and so a recipe can + pin other files without pinning itself. The catalog digest is reported + separately (`catalog.sha256`). +2. **Recipes point at existing scripts.** A recipe names a Compose service and + exact argv, and pins the scripts behind it. There is no second scripting + language and no inline code: shell `-c`, interpreter inline-code flags + (`node -e`, `python -c` and similar), `eval`, an `env` wrapper and bare + shell syntax (`|`, `&&`, `$(…)`, backticks) are refused. Every argv + position is checked, because a service entrypoint may pass any word to + `exec` (this repository's toolchain does). The check is a denylist of + known programs (see Known gaps). For a known program it is fail-closed: + an inline-code or stdin flag (`-s`, `-i`) anywhere after it refuses the + recipe, even after an option value or a script path, because option + values and operands cannot be told apart without each program's own + parser. A shell or interpreter given `-` or no script operand (code from + stdin), a REPL or eval subcommand (`bun repl`, `deno eval`) and a + `data:` URL module given to Node, Bun, Deno or tsx + (`node --import data:text/javascript,…`) are refused too. So are the + string-to-shell forms of package runners and wrappers (`npx -c`, + `npm exec -c`, `pnpm -c`, `yarn exec`, `bun exec`, `nodemon --exec`, + `tsx -e`, `ts-node -e`, `julia -e`, `sudo -s`, `doas -s`, + `git -c`/`--exec`/`--upload-pack`/`--receive-pack`/`submodule foreach`/ + `bisect`/`filter-branch`, `make --eval`, `nix eval`) and + `eval`, `env`, `xargs`, `su`, `runuser`, `ssh`, `nix-shell`, + `concurrently`, `watchexec`, `tmux`, `iex`, the vi and Emacs editors, awk + or sed anywhere in argv, and `watch`, `parallel` or `sg` with a command. +3. **Repository and log text grant no authority.** A recipe that passes every + check is `reviewed`: its pins still match what a reviewer approved. Results + still say `authority: "none"` and `execution: "unavailable"`. A recipe that + claims any provenance other than `repository_script` (for example `log`, + `suggested_action` or `agent_generated`) is refused. +4. **Registration runs nothing.** Reading the catalog, listing it or + inspecting a recipe starts no task process. The only child processes are + read-only Git queries: the target inspector's, and one `git ls-files` + per pinned recipe that proves its pins are tracked files. +5. **Refused recipes are not echoed.** A refused recipe is reported by index, + id and reason only. Its argv, text and any smuggled values are never + returned, so an injected command is not handed back as runnable text. +6. **No fallback.** Ambiguous, stale, untrusted, out-of-scope or + capability-missing recipes are refused. Nothing falls back to a broader + runner, env scope or host process. +7. **Targets use the WU31 schema.** Each result embeds the full + [`hack.target.v0`](./ax-target-result-contract.md) target, and target + refusals pass through unchanged.

It does not prove who + reviewed the recipe: anyone who can edit the repository can edit pins. + Execution must not treat `reviewed` as authorization. +- **Transitive content.** Pins cover the named files and JSON values only. + Nested scripts (for example a `package.json` script that calls another), + dependencies, lockfiles and base images that a pinned file does not pin by + digest are not covered. +- **Compose policy.** The service definition is pinned, not analyzed. The + catalog does not check that the reviewed service lacks host ports, sockets + or home mounts; the reviewer must. +- **Env keys.** Only the overlay selection is compared. Whether the overlay + exists or supplies the scoped keys is not checked. +- **Host profiles.** None are approved, so host-side scripts cannot be + catalogued yet. +- **Inline-code detection is a denylist.** It covers the shells, + interpreters and string-to-shell wrappers listed above. A program it does + not know that evaluates an argument (for example `chroot` or `nsenter` + with no command, `make` variable values such as `X=${shell id}`, or a + reviewed script that evaluates its arguments) is not detected; the + reviewer must check argv, and WU26 execution must not rely on this check + as a sandbox. For a known program it is fail-closed, so it can also refuse + an ordinary argument that looks like an inline flag (`script.sh -c`, + `git clean -x`, `make -e`). Bare `R` is not refused, because a one-letter + word is too common as an ordinary argument. +- **Tracked pins hash working-tree bytes.** A pin must be tracked by Git, + but its digest is of the file in the working tree. An uncommitted local + edit to a tracked file (for example a credential added to a tracked + config, including one hidden with `git update-index --skip-worktree`) is + hashed and its digest can appear in a stale refusal. +- **Input reads are not atomic.** Pinned inputs are read once; an edit during + the read is reported on the next read, not detected in the same one. The + catalog file and the config generation are re-read and compared. diff --git a/docs/reference/cli.md b/docs/reference/cli.md index 533ea57d1..60b029093 100644 --- a/docs/reference/cli.md +++ b/docs/reference/cli.md @@ -24,6 +24,7 @@ hack project [options] | --- | --- | | `hack project owner` | Inspect project ownership | | `hack project target` | Inspect the exact project, checkout, instance and service a command would target (read-only, provisional) | +| `hack project task` | Discover reviewed task recipes without running them (read-only, provisional) | ### Options @@ -82,6 +83,31 @@ hack project target [options] | `--help, -h` | Show help | | `--version, -v` | Show version | +## `hack project task` + +Discover reviewed task recipes without running them (read-only, provisional) + +### Usage + +```bash +hack project task [options] +``` + +### Subcommands + +| Command | Summary | +| --- | --- | +| `hack project task list` | List reviewed task recipes and refusals for the target (read-only, provisional; runs nothing) | +| `hack project task inspect ` | Show one reviewed task recipe: argv, service, env scope, effects and pins (read-only, provisional; runs nothing) | + +### Options + +| Option | Description | +| --- | --- | +| `--no-interactive` | Never prompt: apply documented defaults or fail with E_INTERACTIVE_REQUIRED (also via HACK_NO_INTERACTIVE=1) | +| `--help, -h` | Show help | +| `--version, -v` | Show version | + ## `hack init` diff --git a/docs/reference/mcp-tools.md b/docs/reference/mcp-tools.md index 2e8b10d2c..ff4b76830 100644 --- a/docs/reference/mcp-tools.md +++ b/docs/reference/mcp-tools.md @@ -39,6 +39,8 @@ Every tool sets `openWorldHint: false`.
