From 057916ac9ecefe6e8f13e4a2c37bdb21d288444d Mon Sep 17 00:00:00 2001 From: darthsharp <48331467+darthsharp@users.noreply.github.com> Date: Sun, 25 Oct 2026 17:19:40 +0100 Subject: [PATCH 1/3] **refactor!: remove `FeatureRequestTemplate` and request template; implement external process handling and GitHub CLI integration** - Removed `FeatureRequestTemplate` and `request.template.md` to streamline feature creation logic. - Added `ExternalProcessRunner` and `ExternalProcessResult` for managing external processes with captured output. - Introduced `GhCommandRunner`, `GhCommandResult`, and `GhExecutableLocator` to integrate GitHub CLI (`gh`) functionality. - Added extensive tests for GH command execution, process handling, and executable discovery. --- CLAUDE.md | 1 + Directory.Packages.props | 1 + .../02-repository-initialisation.md | 15 +- .../feature-packages/03-feature-management.md | 153 ++- .../05-gates-and-checklists.md | 4 +- docs/feature-packages/06-skill-foundation.md | 3 +- .../feature-packages/09-discuss-and-intake.md | 18 +- docs/feature-packages/10-refine.md | 4 +- docs/feature-packages/16-bugfix-profile.md | 4 +- docs/feature-packages/17-quick-profile.md | 4 +- docs/feature-packages/18-upgrade.md | 3 +- docs/feature-packages/README.md | 11 +- research/shade-kit-concept.md | 4 +- skills/shade-kit-diagnose/SKILL.md | 2 +- skills/shade-kit-new/SKILL.md | 10 +- skills/shade-kit-quick/SKILL.md | 2 +- skills/shade-kit-refine/SKILL.md | 2 +- skills/shade-kit-research/SKILL.md | 2 +- .../Commands/Feature/FeatureSourceData.cs | 3 +- .../Feature/New/FeatureNewCommandOptions.cs | 13 +- .../Feature/Show/FeatureShowCommand.cs | 3 +- .../Output/CliErrorMapper.cs | 36 +- .../ShadeKitCliExitCodes.cs | 10 +- .../CreativeCoders.ShadeKit.Core.csproj | 1 + .../InvalidFeatureSourceException.cs | 5 +- .../Features/FeatureIdFactory.cs | 141 ++- .../Features/FeatureIdentity.cs | 9 +- .../Features/FeatureRequestTemplate.cs | 66 -

Agent contract: every agent-facing command takes options derived from `JsonCommandOptions` (`--json`). In JSON mode it writes one `CliJsonEnvelope` (`ok`, `data`, `warnings`, `error`) through `ICliJsonWriter` to stdout and nothing else; on an expected failure it writes a failure envelope and throws `CliCommandAbortException` with `PrintMessage = false`. Commands get `ShadeKitCommandContext` (`Output/`) injected: `RunAsync` runs the core call (optionally with the kit store) with the run's cancellation token and turns mapped failures into the failure envelope / `CliCommandAbortException`, and `WriteSuccess` writes the single success envelope or the plain warnings and lines; commands do not use `ICliJsonWriter`, `CliErrorMapper`, or `CliCommandAbort` directly (only `version`, which cannot fail, writes its envelope through `ICliJsonWriter`). Core exceptions are mapped to exit code, error code, and message only in `CliErrorMapper`. Exit codes are grouped by area (10–19 store, 20–29 format, 30–39 features, 40–49 phases and gates, 255 host); 2 (invalid arguments, usage) and 130 (canceled) are outside the ranges; every exit code has a kebab-case error code in `ShadeKitCliErrorCodes`; codes that only appear as warnings are in `ShadeKitCliWarningCodes`. - Versioned JSON files in `.shadekit/` are read and written only through `IKitStore.ReadJsonAsync`/`WriteJsonAsync`. Each file type has a format id in `FormatIds` and a definition in `FormatRegistry.CreateDefault()`; raising a format version means a new table entry plus an `IFormatMigration` step and a test that migrates a fixture from the previous version. Document models derive from `VersionedDocument`; nested classes need their own `[JsonExtensionData] Dictionary` to keep unknown fields. - Text file content is held as `TextFileContent` (lines, UTF-8 BOM flag, final-line-ending flag), never as `byte[]`, and is written only through `ITextFileWriter` (`IKitStore.WriteFileAsync` uses it for `.shadekit/`). The writer is the only place that encodes to bytes; it resolves the line ending with `ILineEndingResolver`: git (attributes as git's `convert_attrs`: resolved `text`, legacy `crlf` only while `text` is unspecified; `-text` → no decision, `eol` attribute, `text=input`/`crlf=input` → LF, `core.autocrlf`, `core.eol` for text files; config values and a failing `git` cached per repository root for the resolver's lifetime, i.e. one command run; a `git` that is installed but fails gives a `GitAttributesUnavailableWarning`, a missing one (`GitNotFoundException`) none; `ILineEndingResolver.PrepareAsync` / `IKitStore.PrepareLineEndingsAsync` read the attributes of several files with one `git check-attr`, as `init` and `feature new` do) → `.editorconfig` `end_of_line` (parsed files kept per resolver while their write time, size, and Unix mode are unchanged) → operating system. Paths reach the writer and the resolvers as `RepositoryFile`, checked once where it is created (`RepositoryFile.Resolve`, or `KitStore` for `.shadekit/`). Lines are split at CRLF, LF, and a lone CR. Files, the versioned JSON files included, are read as strict UTF-8; an unreadable `.editorconfig` falls back with an `EditorConfigUnreadableWarning`, one the parser cannot evaluate (e.g. an overflowing numeric-range glob, or a glob that expands into more than 10 000 patterns, checked before the parser expands it) with an `EditorConfigInvalidWarning`. +- External tools (`git`, and `gh` for tracker issues in `feature new`) are started only through the internal helpers in `src/CreativeCoders.ShadeKit.Core/Processes/` (`PathExecutableSearch`: absolute `PATH` entries only; `ExternalProcessRunner`: absolute path, no shell, process tree killed on cancellation), behind one runner interface per tool (`IGitCommandRunner`, `IGhCommandRunner`). HTTP goes through `IHttpClientFactory` with the named client `HttpUrlContentReader.HttpClientName` (`Microsoft.Extensions.Http`), not a typed client, because the services that use it are singletons. Tests never start `git` or `gh` and never send a request: they fake the runner or use `tests/Shared/StubHttpMessageHandler.cs`. - Core services are registered with `services.AddShadeKitCore()`. ```sh diff --git a/Directory.Packages.props b/Directory.Packages.props index f18a742..34ed6dc 100644 --- a/Directory.Packages.props +++ b/Directory.Packages.props @@ -20,6 +20,7 @@ + diff --git a/docs/feature-packages/02-repository-initialisation.md b/docs/feature-packages/02-repository-initialisation.md index e82d719..d04445e 100644 --- a/docs/feature-packages/02-repository-initialisation.md +++ b/docs/feature-packages/02-repository-initialisation.md @@ -2,7 +2,7 @@ | | | |---|---| -| Status | Draft, 2026-10-14, updated 2026-10-17 (template conventions), 2026-10-18 (implementation state; code review rework: exit codes 14 and 24, `.gitignore` rule, separator line), 2026-10-22 (code review verification of package 03: `trackers` id prefixes validated), 2026-10-23 (rework of file content handling: line endings of `.gitignore`, `CLAUDE.md`, and `AGENTS.md`, strict UTF-8, warnings; code review: `editorconfig-invalid`, legacy `crlf` attribute, `text=input`), and 2026-10-24 (documentation check: exit code 14 also for the `request.md` template, warnings sentence, resolved open point removed).

Commands get `ShadeKitCommandContext` (`Output/`) injected: `RunAsync` runs the core call (optionally with the kit store) with the run's cancellation token and turns mapped failures into the failure envelope / `CliCommandAbortException`, and `WriteSuccess` writes the single success envelope or the plain warnings and lines; commands do not use `ICliJsonWriter`, `CliErrorMapper`, or `CliCommandAbort` directly (only `version`, which cannot fail, writes its envelope through `ICliJsonWriter`). Core exceptions are mapped to exit code, error code, and message only in `CliErrorMapper`. Exit codes are grouped by area (10–19 store, 20–29 format, 30–39 features, 40–49 phases and gates, 255 host); 2 (invalid arguments, usage) and 130 (canceled) are outside the ranges; every exit code has a kebab-case error code in `ShadeKitCliErrorCodes`; codes that only appear as warnings are in `ShadeKitCliWarningCodes`. - Versioned JSON files in `.shadekit/` are read and written only through `IKitStore.ReadJsonAsync`/`WriteJsonAsync`. Each file type has a format id in `FormatIds` and a definition in `FormatRegistry.CreateDefault()`; raising a format version means a new table entry plus an `IFormatMigration` step and a test that migrates a fixture from the previous version. Document models derive from `VersionedDocument`; nested classes need their own `[JsonExtensionData] Dictionary<string, JsonElement>` to keep unknown fields. - Text file content is held as `TextFileContent` (lines, UTF-8 BOM flag, final-line-ending flag), never as `byte[]`, and is written only through `ITextFileWriter` (`IKitStore.WriteFileAsync` uses it for `.shadekit/`). The writer is the only place that encodes to bytes; it resolves the line ending with `ILineEndingResolver`: git (attributes as git's `convert_attrs`: resolved `text`, legacy `crlf` only while `text` is unspecified; `-text` → no decision, `eol` attribute, `text=input`/`crlf=input` → LF, `core.autocrlf`, `core.eol` for text files; config values and a failing `git` cached per repository root for the resolver's lifetime, i.e. one command run; a `git` that is installed but fails gives a `GitAttributesUnavailableWarning`, a missing one (`GitNotFoundException`) none; `ILineEndingResolver.PrepareAsync` / `IKitStore.PrepareLineEndingsAsync` read the attributes of several files with one `git check-attr`, as `init` and `feature new` do) → `.editorconfig` `end_of_line` (parsed files kept per resolver while their write time, size, and Unix mode are unchanged) → operating system. Paths reach the writer and the resolvers as `RepositoryFile`, checked once where it is created (`RepositoryFile.Resolve`, or `KitStore` for `.shadekit/`). Lines are split at CRLF, LF, and a lone CR. Files, the versioned JSON files included, are read as strict UTF-8; an unreadable `.editorconfig` falls back with an `EditorConfigUnreadableWarning`, one the parser cannot evaluate (e.g. an overflowing numeric-range glob, or a glob that expands into more than 10 000 patterns, checked before the parser expands it) with an `EditorConfigInvalidWarning`. -- External tools (`git`, and `gh` for tracker issues in `feature new`) are started only through the internal helpers in `src/CreativeCoders.ShadeKit.Core/Processes/` (`PathExecutableSearch`: absolute `PATH` entries only; `ExternalProcessRunner`: absolute path, no shell, process tree killed on cancellation), behind one runner interface per tool (`IGitCommandRunner`, `IGhCommandRunner`).

The hint by `Problem` instead of by the type of the inner exception **Decided** on 2026-10-25 (simplification of the rework, approved by the user), so `CliErrorMapper` no longer depends on how the reader failures are wrapped. `CliErrorMapper` also maps the three reader exceptions to 33 with their own message and the same hint, in one arm, as a fallback for a caller that does not wrap them; it stays because FP01-AC8 requires a mapping for every public core exception (**Decided** on 2026-10-25 by the user, instead of internal reader exceptions or an exception list in the AC8 test). **Implemented** (`FeatureIdFactory`, `FeatureSourceReader`, `CliErrorMapper`, `CreateAsync_GhNotFound_ThrowsInvalidFeatureSourceExceptionWithReaderException`, `CreateAsync_TrackerIssueReadFails_ThrowsInvalidFeatureSourceExceptionWithReaderException`, `CreateAsync_UrlContentReadFails_ThrowsInvalidFeatureSourceExceptionWithReaderException`, `Map_GhUnavailable_ReturnsExitCode33WithExceptionMessageAndGhInstallHint`, `Map_TrackerIssueReadFailed_ReturnsExitCode33WithExceptionMessageAndGhSignInHint`, `Map_UrlContentReadFailed_ReturnsExitCode33WithExceptionMessageAndUrlHint`, `Map_InvalidFeatureSourceWithGhUnavailableProblem_ReturnsExitCode33WithGhInstallHint`, `Map_InvalidFeatureSourceWithIssueReadFailedProblem_ReturnsExitCode33WithGhSignInHint`, `Map_InvalidFeatureSourceWithUrlReadFailedProblem_ReturnsExitCode33WithUrlHint`, `Map_InvalidFeatureSourceWithInnerExceptionAndDefaultProblem_ReturnsExitCode33WithSourceHint`, and end to end `FeatureNew_JsonIssueCannotBeRead_Returns33WithGhSignInHintAndChangesNothing`, `FeatureNew_PlainIssueCannotBeRead_Returns33WithGhSignInHint`, `FeatureNew_JsonGhNotFound_Returns33WithGhInstallHint`, `FeatureNew_JsonUrlContentCannotBeRead_Returns33WithUrlHintAndChangesNothing`, `FeatureNew_PlainUrlContentCannotBeRead_Returns33WithUrlHint`). | None | | 34 | `invalid-title` | `new`: a URL source whose host is not in `trackers` without `--title`, a title (from `--title`, the text, the file, or the issue) with a control character, or a title that gives an empty slug (`InvalidFeatureTitleException`). | None | | 35 | `feature-io-failed` | `new`: the hidden staging folder cannot be created or cannot be moved to `features/<id>/`; `drop`: `features/<id>/` cannot be renamed to its hidden dropping folder. In each case the file system reports an IO error or access denied (`IOException`, including `DirectoryNotFoundException`, or `UnauthorizedAccessException`), unless the destination folder of `new` exists by then (exit code 30) or a file is at `features/<id>` (exit code 255). The message names the folder, the operation (`create` or `drop`), and the cause, and points to the write permissions of `features/` and to programs that hold a file open, such as an editor, a virus scanner, or a search indexer (`FeatureIoFailedException`). **Decided** by the user on 2026-10-21 (second code review, finding N01). | None; a staging folder that was already created is removed, the override is untouched | | 36 | `git-identity-missing` | `new`: `user.name` or `user.email` is not set (`GitIdentityNotConfiguredException`).
