Read via ${REVIEW_PR:-0}/${PR_ARG:-} so a same-call prefix survives; reword the instruction to prefix, not edit-in-place. - Deterministically sanitize finding text before it enters the posted Markdown (escape pipes/newlines/backticks, neutralize @-mentions and raw HTML, inert links) β€” the human confirm scan alone is not enough for content leaving the sandbox to a public comment under the user's identity. - Pin the reviewed revision: capture headRefOid, show `reviewed at <sha>` in the report header + comment body, optionally re-check the head at post time so a mid-window push can't make a stale comment look current. - Warn (SWARM_PR_WARN) when the local checkout isn't the PR head, since the in-session verifier reads file:line from local disk, not the PR head. - Validate PR_ARG as a bare number so gh can't be pointed at another repo. - Clean up $TMPD on every step-5 exit (decline / post-failure), not just the success path β€” the deferred cleanup otherwise leaks the PR diff.

R1 (fixing R0-introduced regressions): - Make the stale-head check a real gate that stops before posting, not an advisory echo followed by an unconditional gh pr comment. - Validate the --pr value to ^[0-9]+$ in the model layer before building the shell prefix, closing a PR_ARG assignment-time injection. - Extract headRefOid via gh --jq (no python3 dep) and treat an empty OID as a hard error instead of silently skipping the head guard. - Also require a clean working tree at the PR head (not just HEAD==oid). - Write the comment body with the Write tool, never a fixed-delimiter heredoc a steered finding line could forge. - Restore composer in the skill description. Loop stopped by judgment: it diverged (8 -> 13 findings), and the recurring class (whole publish path is model-interpreted prose) is a named residual β€” extract it into a testable scripts/ helper as a follow-up rather than bolting on more inline shell.
