Based on SOC occupation classification
Structured SRE debugging methodology for aie-matrix production incidents. Use this skill whenever the user is investigating anything that is slow, broken, or behaving unexpectedly in production or staging — including slow deploys, failing health probes, high latency, unexpected restarts, memory pressure, or anything described as "something is wrong" or "why is X taking so long". Also use when writing a post-mortem or runbook entry. The skill enforces a disciplined observe-hypothesize-test loop rather than applying fixes based on intuition.
Gate check before opening a PR: clean build, all tests (unit + integration), spec coverage, doc impact, and a go/no-go verdict. Run after /speckit.implement and before opening a pull request.
Effect-ts coding standard for all server-side packages in aie-matrix (server/agent-host/ and server/*). Use when writing or reviewing services, route handlers, error types, logging, configuration, or background fibers in any of these packages.
Create or update the feature specification from a natural language feature description.
Validate gram notation snippets or files using the gram-lint CLI. Use whenever you need to check whether a gram expression or .map.gram file is syntactically valid — especially when designing format changes, reviewing example files, or verifying that proposed snippets are parseable by the WASM grammar.
Validates Gram notation files and inline snippets using the gram-lint CLI (parse errors, optional s-expression tree). Use when editing or generating .gram files, debugging Gram.parse failures, validating converter output, or when the user mentions gram-lint, Gram syntax, or linting gram documents.

Create and switch to a new git feature branch for the given specification. This command handles branch creation only — the spec directory and files are created by the core /speckit.specify workflow.
$ARGUMENTS
You MUST consider the user input before proceeding (if not empty).
If the user explicitly provided GIT_BRANCH_NAME (e.g., via environment variable, argument, or in their request), pass it through to the script by setting the GIT_BRANCH_NAME environment variable before invoking the script. When GIT_BRANCH_NAME is set:
--short-name, --number, and --timestamp flags are ignoredFEATURE_NUM is extracted from the name if it starts with a numeric prefix, otherwise set to the full branch namegit rev-parse --is-inside-work-tree 2>/dev/nullDetermine the branch numbering strategy by checking configuration in this order:
.specify/extensions/git/git-config.yml for branch_numbering value.specify/init-options.json for branch_numbering value (backward compatibility)sequential if neither existsGenerate a concise short name (2-4 words) for the branch:
Run the appropriate script based on your platform:

--number — the script determines the correct next number automatically--json for Bash, -Json for PowerShell) so the output can be parsed reliablyBRANCH_NAME and FEATURE_NUMIf Git is not installed or the current directory is not a Git repository:
[specify] Warning: Git repository not detected; skipped branch creationBRANCH_NAME and FEATURE_NUM so the caller can reference themThe script outputs JSON with:
BRANCH_NAME: The branch name (e.g., 003-user-auth or 20260319-143022-user-auth)FEATURE_NUM: The numeric or timestamp prefix used
