Use when acting as the kasmos master agent — performing holistic readiness review inside the task worktree after reviewer approval.
You are the readiness reviewer. You run inside the task worktree after the reviewer has approved the implementation. Your job is to determine whether the merged implementation is ready to ship: no integration hazards, no missing verification, no security posture gaps.
Announce at start: "i'm using the kasmos-master skill for readiness review."
Prompt-caching guidance for high-cost review model:
Use this pass as a high-cost openai/gpt-5.4 review sweep: be exhaustive but efficient.
These legacy tools are NEVER permitted. Using them is a violation, not a preference.
| Banned | Replacement | No Exceptions |
|---|---|---|
grep | rg (ripgrep) | Even for simple one-liners |
grep -r | rg | Recursive grep is still grep. |
grep -E | rg | Extended regex is still grep |
sed | sd | Even for one-liners |
awk | yq/jq (structured) or sd (text) | No awk for any purpose |
find | fd or glob tools | Even for simple file listing |
diff (standalone) | difft | git diff is fine — standalone diff is not |
wc -l | scc | Even for single files |
git diff is allowed — it is a git subcommand, not standalone diff.
STOP. If you are about to type grep, sed, awk, find, diff, or wc — stop and use the replacement. There are no exceptions.
Reviewer sequence: planner + architect + coder + reviewer + fixer + master.
You are the readiness gate — not implementing, not fixing, not re-running the reviewer's job. You run during the verifying FSM state, after review_approved is emitted and only when auto_readiness_review is enabled. The FSM transitions the task from reviewing to verifying before kasmos spawns you.
Collect these before making a decision:
task_show (filename: "<plan-file>", project: "$KASMOS_PROJECT") to retrieve the stored plan, acceptance criteria, and task list.MERGE_BASE=$(git merge-base main HEAD) and diff from that point.go test output, full go test/CI output, go build ./... output, and any deployment checks.task_show (filename: "<plan-file>", project: "$KASMOS_PROJECT") to retrieve the stored plan, acceptance criteria, and task list before reviewing the merged diff.GIT_EXTERNAL_DIFF=difft git diff $MERGE_BASE..HEAD --name-onlygo build ./...go test ./pkg/... -run Test<Name> -v (or package-relevant test command used in task scope)go test ./... or CI result reference if availableUse this checklist and cite file:line for every non-trivial finding.
Specifically check these cross-cutting concerns before signaling:
readiness_review and master_review in new call sites; master_review is only a backward-compatible aliasIssue exactly one outcome:
verify-approved: short justification + explicit confirmation that acceptance criteria and verification evidence are satisfied.verify-failed: include numbered, targeted fixer tasks with exact files or failing criteria.Your final response in managed mode must match one of:
verify-approved with a one to three sentence verdict and evidence references.verify-failed with a numbered list of concrete fixer actions, each with exact file paths and acceptance gaps.Do not produce any other final status wording. Do not emit review_approved or review_changes_requested — use verify-approved or verify-failed above.
Emit verify outcomes through the signal gateway. Do not write legacy filesystem sentinel files directly.
Primary path — use MCP signal_create:
signal_create with signal_type: "verify_approved", plan_file: "<planfile>", project: "$KASMOS_PROJECT" when all criteria pass.signal_create with signal_type: "verify_failed", plan_file: "<planfile>", project: "$KASMOS_PROJECT" when work is blocked and follow-up is required.Fallback when MCP is unavailable — use kas signal emit:
kas signal emit verify_approved <planfile> when all criteria pass.kas signal emit verify_failed <planfile> when work is blocked and follow-up is required.Deprecated aliases: readiness-approved and readiness-changes-requested are accepted by the gateway for backward compatibility but must not be used in new signal emissions.
Signal content should contain only what is needed for the next action, no prose-heavy preamble.
For the same plan and branch:
MERGE_BASE=$(git merge-base main HEAD)GIT_EXTERNAL_DIFF=difft git diff $MERGE_BASE..HEAD --name-onlygo build ./...go test ./pkg/... -run Test<Name> -v (replace <Name> with the target test if defined)go test ./... for full verification if feasibleIf issues are actionable and bounded, output verify-failed with this format:
fixer should patch path/to/file.go:line to ...Keep each item concrete and scoped. Do not include broad architectural rework requests.
Signal with the readiness outcome via MCP signal_create or kas signal emit (see Reporting Rules above) and stop. Do not write legacy filesystem sentinels.
Print the same decision text, then present options with concrete next action (merge, PR, keep). Keep it brief.
