sandstorm-cli/skills/stack-failure-diagnostic/SKILL.md
Use this skill when the user reports a stack appears broken, stuck, looping, failed, or otherwise not working — and wants to understand WHY (not just restart it). Trigger phrases include: 'stack N doesn't seem to be working', 'stack N isn't working', 'stack N failed for some reason / why did stack N fail / what went wrong with stack N', 'stack N seems stuck / got stuck / stuck in an infinite loop / keeps looping / did N loops and failed', 'take a look at stack N, something went wrong / it's broken / something's clearly wrong', 'stack N hit NEEDS HUMAN INTERVENTION / keeps failing / errored out', 'figure out what's happening / going on with stack N', 'give me a summary of what happened with stack N / diagnose stack N'. The skill reads the stack's dual-loop artifacts (phase timings, review verdicts, execution summaries) from inside its container and returns one structured report — avoiding the 40+ Bash-exploration sub-turns the orchestrator would otherwise make. Make sure to use this skill for ANY request that involves diagnosing a stack's failure, loop behavior, or why it stopped working — even when the user phrases it gently (e.g., 'doesn't seem to be working', 'not sure what's going on', 'can you take a look') as long as there is a failure or malfunction signal present. Falling back to raw Bash exploration of the stack's internals costs 1M+ tokens. Do NOT trigger for: status-only 'is stack N done?' / 'what's the status of stack N' (that's check-and-resume-stack), diff/logs inspection on a working stack with no failure signal (stack-inspect), or creating a new stack.

- Use this skill when the user reports a stack appears broken, stuck, looping, failed, or otherwise not working — and wants to understand WHY (not just restart it).

/stack-failure-diagnostic
Extract the stack ID from the user's message, then run the script exactly once:
bash "$SANDSTORM_SKILLS_DIR/stack-failure-diagnostic/scripts/diagnose.sh" <stack-id>
The script prints a structured multi-section report. Relay the relevant parts to the user — do NOT re-read the underlying files yourself, do NOT run additional Bash/Grep/Read against the stack's container. The report already has everything you need to answer "what went wrong".
If the script prints NOT_FOUND, report it and ask for the exact ID. If it prints NO_ARTIFACTS, the stack has no dual-loop artifacts yet (never ran or was just created); tell the user that and stop.

onomojo/stack-teardown
testing
VerifiedTrustedCommunity
Use this skill ONLY when the user has EXPLICITLY asked to tear down, destroy, remove, or dismantle a named Sandstorm stack. Trigger phrases include: 'tear down stack X', 'destroy stack X', 'remove stack X', 'dismantle stack X', 'clean up stack X and all its containers', 'I'm done with stack X, kill it'. This skill stops containers, removes the workspace, and archives the stack — it is IRREVERSIBLE and can lose unpushed work. Do NOT trigger on ambiguous phrases like 'clean up', 'reset', 'start over', 'remove the old one', 'stack is broken', or anything that might imply teardown without literal user words like tear down / destroy / delete. Do NOT trigger for: stopping containers (that's pause, not teardown), checking status, failure recovery, or as a precursor to creating a new stack. When in doubt, ASK the user before running.

onomojo/stack-pr
tools
VerifiedTrustedCommunity
Use this skill whenever the user wants to record/link/associate a pull request with an existing Sandstorm stack. Trigger phrases include: 'record PR #N for stack X', 'set PR for stack X to #N', 'link PR https://github.com/.../pull/N to stack X', 'save the PR info on stack X', 'stack X's PR is #N'. Use this after a PR has been opened externally (via gh CLI, the GitHub UI, or push_stack's downstream flow) and the user wants the Sandstorm registry to know about it — the stack status flips to pr_created and the URL/number are stored. Do NOT trigger for: creating the PR itself (that's a separate gh CLI / push flow), tearing down the stack, checking stack status, or unrelated PR operations like merging or closing.

onomojo/stack-inspect
testing
VerifiedTrustedCommunity
Use this skill whenever the user wants to see DETAILED output, logs, or uncommitted changes from a specific Sandstorm stack. Trigger phrases include: 'show me the output of stack X', 'what did stack X log', 'show the task output for X', 'show container logs for stack X', 'what changed in stack X', 'show me the diff in stack X', 'what's happening inside stack X', 'dump stack X's output', 'get logs for stack X's claude container'. The skill covers three read-only probes — task output, container logs, and uncommitted diff — as subcommands. Do NOT trigger for: a quick status check (that's check-and-resume-stack), listing all stacks (that's list-stacks), or anything that modifies state. Prefer the narrower subcommand (output / logs / diff) over 'all' when the user is specific about what they want.

onomojo/spec-and-dispatch
development
VerifiedTrustedCommunity
Use this skill whenever the user wants to take an existing ticket / issue, run the Sandstorm spec quality gate on it, and then (once it passes) create a stack with the ticket's verbatim body as the initial task. Trigger phrases include: 'take ticket N and build it', 'spec and dispatch N', 'fire up a stack for ticket N', 'let's work on #N', 'start issue N in a stack', 'create a stack for issue N, run the gate first'. This skill is the full start-to-dispatch flow for a ticket: fetch ticket → spec_check → (refine loop if needed) → create_stack with gateApproved=true and the ticket body as the initial task. Do NOT trigger for: dispatching follow-up work to an EXISTING stack (that's the sandstorm / check-and-resume flow), running the spec gate in isolation (that's the sandstorm-spec skill), or creating a stack without a ticket.
