From cc140c87e2de4a3a29aef9d54e4636795ea0a7ba Mon Sep 17 00:00:00 2001 From: Dimitri Kennedy Date: Mon, 19 Oct 2026 11:57:55 -0400 Subject: [PATCH 01/11] feat(agents): shared AX target and result contract with a read-only inspector Add a provisional target/result decision record and a read-only target inspector with CLI and MCP parity (HACK-1144, WU31). - `hack project target [--json]` resolves the exact project, checkout, runtime instance, optional service, env overlay selection and a Hack config generation from local files only. It performs no registry write, engine call or Git mutation, and reports runtime as not probed. - `hack.project.target` (read-only MCP tool) spawns the same command and passes selection through unresolved, so every resolution refusal is the CLI's. Its data is the CLI envelope re-validated against the contract. - Refusals are a closed, value-free catalogue (reason, stage, retry) that reuses existing error codes. `--expect-generation` refuses stale config; a config change during the read is refused instead of snapshotted. - Extract the Compose project name resolver from commands/project.ts so the inspector and commands share one implementation. - Paired CLI/MCP fixtures: two projects, a linked-worktree branch and an explicit instance, conflicting selectors, stale generation, ambiguous equal names, a moved checkout, detached worktree and no-write checks. Names, fields and reasons are provisional pending compatibility review.

Every command name, +tool name, field, reason and retry value on this page can still change in the +agent-experience (AX) compatibility review. It is not a stable interface +promise. Fields and codes that the review must confirm are marked +_provisional_ below. + +This page records how Hack names the thing an agent wants to act on (the +**target**), how a read-only inspector reports it, and how adapters (CLI and +MCP) share one result shape. The first implementation is the read-only +inspector `hack project target` and its MCP tool `hack.project.target`. + +## Decisions + +1. **A target is an exact tuple, not a name.** It is the project, the checkout, + the runtime instance, an optional service, the env overlay selection and a + config generation, plus the selector kind and the observation time. A + project name alone is never a target. +2. **Git branch is not runtime identity.** The checkout reports its current Git + branch, but the runtime instance is a separate field. An explicit instance + selector (`--branch`) wins over the branch-derived default, and the + inspector never creates, switches or deletes Git branches or worktrees. +3. **References grant no authority.** A resolved target identifies scope only + (`authority: "none"`). A caller that acts on it must revalidate at its own + effect boundary, for example by passing the generation it inspected. +4. **Equal names are not merged.** Registration ownership is decided by the + exact checkout root (or a recorded linked worktree of a registration), never + by name. Two registrations that share a name are refused as + `ambiguous_project` when selected by name, and are never renamed. +5. **Generation covers Hack config only.** The generation fingerprints + `.hack/hack.config.json`, `.hack/hack.toml` and `.hack/docker-compose.yml`. + Ordinary source edits do not change it. Qualifying an immutable source + revision is a separate, explicit concern and is not part of this contract. +6. **No fake atomic snapshot.** The inspector reads the generation before and + after resolving the other fields. If it changed during the read, the result + is the `generation_changed_during_read` refusal, not a mixed snapshot. +7. **Snapshot reads have no side effects.** No registry write (not even the + last-seen touch other commands perform), no engine or Docker call, no + startup, repair or global sync, and no Git mutation. The only child + processes are read-only Git queries that existing project commands already + run. +8. **Readiness is not claimed.** The snapshot does not probe the runtime. It + reports `runtime: { observed: false, reason: "not_probed" }` instead of + guessing whether containers exist or are healthy. +9. **One semantics across adapters.** The MCP tool spawns the same CLI command + and passes selection through unresolved, so every resolution refusal comes + from the same code. There is no MCP-only selection policy. The MCP server + only checks input grammar before spawning; any value it accepts is then + judged by the CLI. +10. **Errors reuse existing codes.** Refusals reuse the stable CLI error codes + in `HACK_ERROR_CODES`. The closed `detail.reason` is the discriminator. + Adding a dedicated code (for example for staleness) is left to the + compatibility review. + +## Commands + +| Surface | Name (_provisional_) | Class | +| --- | --- | --- | +| CLI | `hack project target [--project=…\|--path=…] [--branch=…] [--service=…] [--env=…] [--expect-generation=…] [--json]` | read-only | +| MCP | `hack.project.target` (inputs `projectName`, `path`, `branch`, `service`, `env`, `expectGeneration`) | read-only | + +The MCP tool runs `hack project target --json` with the same options.

Paired CLI/MCP fixtures now cover env selection (project default, explicit overlay, base), explicit instance slugging (Feature/X -> --feature-x), two registrations owning one checkout, config_parse_failed, compose_parse_failed and generation_input_too_large. A stubbed CLI proves the MCP tool re-validates the envelope, and the validator's code/message consistency check has direct tests. Restores the buildEnvExplainArgs JSDoc.

They read reviewed recipes for existing repository scripts from `.hack/tasks.json` and judge each one against the exact WU31 target: exact argv, Compose service, workdir, env scope, required capabilities, effects, prerequisites, checks, cleanup and pinned provenance (file and JSON pointer SHA-256 digests plus the canonical service definition digest). Nothing is executed. Results carry `authority: "none"` and `execution: "unavailable"`; there is no shell endpoint or execution path. Closed refusals cover ambiguous ids, untrusted (log/suggested) provenance, inline code or shell syntax in argv, host runners (no approved profile), missing capabilities, wrong env scope, unknown services, missing or escaping inputs and stale pins. Refused recipes are reported without their argv or text. The repository's own toolchain recipes (models, check, rust-check) are pinned and checked by the new test.

Machine-local entries are excluded under the legacy `.dev` project directory as well as `.hack`. The inline-command denylist now covers package runners (`npx -c`, `npm exec -c`, `pnpm -c`, `yarn exec`, `bun exec`), TypeScript runners, privilege wrappers, `git -c`/`--exec`/`submodule foreach`, `make --eval`, `deno run -`, Elixir and editor forms. Docs no longer describe the check as fail-closed beyond known programs. The registration test now proves the spawn recorder saw git calls.

A dash version suffix (`node-22 -e`) now names the same interpreter as `node22`. Ordinary `git push -u origin main`, `git fetch origin` and `node-22 script.js` argv still pass.
