📝 Walkthrough

Walkthrough

The pull request replaces the standalone Swift script with a SwiftPM executable. It adds configuration loading and validation, separate entry points and functions, workflow options and conditions, captured values, built-ins, and command execution. It updates the examples, documentation, build targets, and tests.

Changes

Executable and CLI

Layer / File(s)	Summary
SwiftPM executable and CLI Makefile, Package.swift, Sources/cm/CLI/*, Sources/cm/main.swift, Sources/cm/CommandError.swift, Sources/cm/Version.swift, Tests/CommandManagerTests/*, README.md, cm.swift	The build and install targets use SwiftPM’s release executable. The CLI parses options, prints general and function help, and handles missing configuration. The old script is removed, and tests and documentation use the executable workflow.

Configuration and workflow

Layer / File(s)	Summary
Configuration and entry-point model Sources/cm/Configuration/*, Tests/CommandManagerTests/ConfigurationTests.swift, Tests/CommandManagerTests/EntryPointTests.swift, Tests/CommandManagerTests/Support.swift, examples/cm.json, README.md	Configuration separates runnable entryPoints from reusable functions. Decoding and validation reject obsolete fields, unknown keys, duplicate names, invalid definitions, and function-call cycles.
Workflow values, arguments, and conditions Sources/cm/Workflow/*, Sources/cm/Configuration/Configuration.swift, Tests/CommandManagerTests/ComparisonTests.swift, Tests/CommandManagerTests/WorkflowTests.swift, Tests/CommandManagerTests/CoverageRegressionTests.swift, README.md	Workflow steps support argument templates and spreads, captured runtime values, string comparisons, and recursive conditions. Validation checks references and output definitions; tests cover valid and invalid configurations and runtime values.
Workflow execution and builtins Sources/cm/Execution/*, Sources/cm/CLI/Output.swift, Sources/cm/Execution/Runner.swift, Tests/CommandManagerTests/*, README.md	The runner executes commands, nested functions, and built-ins. Command execution supports captured output and exit statuses. Built-ins cover paths, Git, JSON lookup, environment export, logging, and executable hashing. Redaction applies to command output and errors.

Priority: ➖ Normal

Estimated code review effort: 5 (Critical) | ~90 minutes

Change: Feature

Merge Risk: 🟡 Moderate · up to 25c9d

When a workflow passes a value that starts with -- to a helper that declares options, the helper can read that value as a flag. The helper then runs with the wrong options or fails. Fix this before merging.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 25c9d

The new workflow format can run programs with the invoking user's environment and reuse their output. No verified security defect or privilege escalation is shown, but the safety of using configuration from a less-trusted source and the comparison with the replaced script remain unresolved.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — A selected configuration can cause any command it defines to run with the invoking process's environment and effective OS identity. Exported variables, including PATH, can affect later commands and nested functions. Evidence does not establish a remote entrypoint or an elevated production deployment.

Security Findings and Attack Paths

• inferred — If an actor can replace a configuration consumed by a more-trusted invocation, its validated command definitions can direct that invocation's process authority. The reviewed evidence does not show that such an actor or invocation exists, so this is a conditional trust path, not a verified PR security finding.

Trust Boundaries and Controls

• observed — Configuration validation checks structural constraints, references, and cycles, and direct CLI invocation is limited to entry points. Those checks do not establish who may author a configuration; file ownership and selection remain the operative trust boundary.
• observed — Nonempty settings and saved results marked sensitive enter the redaction set for later runner messages. A configured export can nevertheless pass a rendered value to child processes, and the echo control does not filter output produced by those processes.

Resilience and Maintainability Implications

• observed — Captured stdout uses a per-attempt private temporary directory and file, with deferred cleanup on normal return or handled errors. Signal handlers are restored after process waiting. Deferred cleanup cannot itself establish what happens to a capture file if the parent process is forcibly terminated.

Hardening Proposals

• proposed — For use under a shared or elevated identity, specify who may select or modify configuration and constrain inherited credentials and environment to the steps that need them. Treat command output, including captured output and stderr, as potentially sensitive rather than relying on command-echo redaction.

- Around line 30-41: Update nested-call argument handling in run and
bindArguments so only literal --name templates from the configuration are parsed
as helper options; pass rendered dynamic values and spread elements
positionally, even when they begin with --. Preserve parsing of raw CLI options
for the entry point.
