From 3896f0443b6c90744497b05ff4625c22e24754d2 Mon Sep 17 00:00:00 2001 From: Kyle Sexton <153232337+kyle-sexton@users.noreply.github.com> Date: Sat, 25 Jul 2026 11:43:51 -0400 Subject: [PATCH 01/12] feat(source-control): explicit-autopilot merge-rung exception with fresh-agent resolution MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds one named, explicit-argument exception to the babysit-loop merge rung: typing the literal `autopilot` tier argument widens that single invocation's merge authority up to C3, dispatching a fresh independent frontier-tier agent (sharing no context with the PR's authoring/reviewing sessions) to resolve needs-human labels, security findings, and contradictory review threads through babysit-prs's existing guarded-mutation path before the deterministic gate runs. C4-structural and C5-untrusted-provenance stay unconditionally human-merge — no rung, seam, or argument, including this one, ever reaches them, per the autonomy matrix's own promotion contract.

Version and delivery (P1): plugin.json 0.26.9 -> 0.27.0 with a matching CHANGELOG entry — per docs/MIGRATION-PLAYBOOK.md the manifest version is the update cache key, so an unbumped plugin never delivers the exception to an installed consumer. Confirmed against the current plugins reference fetched this session (https://code.claude.com/docs/en/plugins-reference): "Setting this pins the plugin to that version string, so users only receive updates when you bump it." Marketplace description (P2): the plugin.json description no longer claims merge-rung raises bind only from the team-tracked layer — it now says STANDING raises do and names the one exception plus the C4/C5 floor. README.md regenerated with scripts/generate-catalog.mjs (the catalog block is generated, CI-checked, never hand-edited). docs/conventions/config-cascade/README.md carried the same stale claim and is corrected too. Eval alignment (P2): babysit-loop eval 1 graded the exact invocation this change widens as "stays c2-mechanical", so running it would have rejected the intended behavior. It now distinguishes the two argument-shaped raises on that line — the typed autopilot tier keyword widens this one invocation to C3; the --merge full-autonomy dimension argument is still ignored — and asserts the persist- nothing and C4/C5-floor properties. New eval 4 covers the safety half that had no coverage: a tier resolved from babysit_loop_tier or babysit_default_tier rather than typed does NOT widen the merge dimension. Inheritance paths closed: the exception's "never inherited, never defaulted" clause named only babysit_loop_tier. config-resolution.md and babysit-loop SKILL.md now state that no config layer or key supplies the keyword, calling out babysit_default_tier explicitly as a babysit-prs userConfig scalar that is not a loop-lane key. babysit-prs SKILL.md was 4 lines over the 500-line hard cap after the merge; the security/P1 exception detail moves to reference/safety.md's new "Security/P1 escalation: the one named exception" subsection, where it is also stated as a contract on how the lane dispatches rather than a claim the dispatch presents about itself. --- README.md | 2 +- docs/conventions/config-cascade/README.md | 2 +- .../source-control/.claude-plugin/plugin.json | 4 +-- plugins/source-control/CHANGELOG.md | 25 +++++++++++++++++++ .../reference/config-resolution.md | 18 +++++++++---- .../skills/babysit-loop/SKILL.md | 15 +++++++---- .../skills/babysit-loop/evals/evals.json | 25 ++++++++++++++++--- .../skills/babysit-prs/SKILL.md | 11 +++----- .../skills/babysit-prs/reference/safety.md | 23 +++++++++++++++++ 9 files changed, 99 insertions(+), 26 deletions(-) diff --git a/README.md b/README.md index 1c56bdc09f..5da7eb80d0 100644 --- a/README.md +++ b/README.md @@ -80,7 +80,7 @@ user opts in with `/plugin enable`; an existing install is never flipped by cata - [`eol-normalizer`](plugins/eol-normalizer) — Normalize a written file's working-tree line endings to its .gitattributes eol value on edit — symmetric CRLF/LF driven by git check-attr, advisory and never blocking. - [`powershell-format`](plugins/powershell-format) — Auto-format and lint PowerShell on edit via PSScriptAnalyzer, only when a PSScriptAnalyzerSettings.psd1 governs the repo — using the consuming repo's own analyzer settings. - [`actionlint`](plugins/actionlint) — Lint GitHub Actions workflow files on edit via actionlint, surfacing findings as advisory context. -- [`source-control`](plugins/source-control) — Git and GitHub delivery workflow: /commit (Conventional Commits + Co-Authored-By trailer via safe heredoc mechanics), /pull-request (prep, create, CI monitoring, review-comment triage, merge, CI-log fetch), /babysit-prs (self-pacing fleet loop — safe by default; opt-in worker/autopilot tiers add gate-checked merge and thread resolution behind a deterministic Python engine), /babysit-loop (the loop-lane merge lane: a standing or drain loop that invokes babysit-prs per cycle, configured through repo-scoped babysit_loop_* keys on the layered source-control.md seam, with merge authority human-only until the target repo's tracked config adopts the lane, a gate-proven C2-mechanical baseline once adopted, and merge-rung raises binding from the team-tracked layer only), /worktree (create, status, cleanup, audit for parallel-session isolation), /setup (check the effective commit-subject / PR-title convention merged across its config layers and the babysit-prs config, or apply — interview the repo and write the convention config to a chosen layer), and /resolve-conflicts (intent-first merge/rebase conflict resolution with a semantic-conflict sweep — never --abort).

C5 becomes a provenance test on the PR itself rather than a lookup of the close-linked item's stamp, so a fork PR closing an internally classified C2/C3 item stays outside the exception. Human blocking feedback and merge conflicts are named as outside the pre-escalation dispatch: the former stays a stop-and-ask condition, the latter routes to the merge-only conflict path, never a rebase. --- docs/conventions/loop-lane/CHANGELOG.md | 9 +- docs/conventions/loop-lane/README.md | 31 ++++- plugins/source-control/CHANGELOG.md | 14 +++ .../reference/config-resolution.md | 10 +- .../skills/babysit-loop/SKILL.md | 112 ++++++++++++------ .../skills/babysit-loop/evals/evals.json | 5 +- 6 files changed, 138 insertions(+), 43 deletions(-) diff --git a/docs/conventions/loop-lane/CHANGELOG.md b/docs/conventions/loop-lane/CHANGELOG.md index 7d8eb074fa..9e9cc78d37 100644 --- a/docs/conventions/loop-lane/CHANGELOG.md +++ b/docs/conventions/loop-lane/CHANGELOG.md @@ -17,7 +17,14 @@ A change to the autonomy-ladder invariant is a major bump per this file's own ru to and including C3, in a repository that has already adopted the baseline rung.

From cf16f30c9929596b47dab97daa6f967dd54424b6 Mon Sep 17 00:00:00 2001 From: Kyle Sexton <153232337+kyle-sexton@users.noreply.github.com> Date: Sun, 26 Jul 2026 04:03:49 -0400 Subject: [PATCH 09/12] fix(source-control): re-key the merge widening to a dedicated paired raise token An independent audit of the final diff found the widening keyed to bare token-presence of the pre-existing autopilot tier keyword, which was merge-inert before this change: every saved invocation, alias, or expanded template already passing autopilot would have silently acquired C3 merge authority, and the two trigger phrases the description added ("drain hard", "merge everything you can in autopilot") invited a model to compose the keyword from a request that never contained it. The exception now fires only when the invocation's own argument line types both the autopilot tier keyword AND the dedicated raise argument --merge c3-this-run. The raise token exists for this exception alone, so its presence cannot be a leftover: autopilot alone stays merge-inert beyond the tracked rung (its pre-exception semantics), c3-this-run is not a rung name and is invalid in any config layer, and the token is never composed by a model on the caller's behalf. The safer-cap rule becomes mutually exclusive with the raise by grammar - every other merge value only ever lowers. The two inviting trigger phrases are removed.

Also fixes three bare reference/... cites introduced by the condensation to full babysit-prs/reference/... paths so the internal-ref check resolves them, and trims the frontmatter description under the 1536-char listing cap. --- .../skills/babysit-loop/SKILL.md | 252 ++++++++---------- .../skills/babysit-prs/SKILL.md | 3 +- 2 files changed, 107 insertions(+), 148 deletions(-) diff --git a/plugins/source-control/skills/babysit-loop/SKILL.md b/plugins/source-control/skills/babysit-loop/SKILL.md index 0b0f74fd89..3e59b97d80 100644 --- a/plugins/source-control/skills/babysit-loop/SKILL.md +++ b/plugins/source-control/skills/babysit-loop/SKILL.md @@ -1,6 +1,6 @@ --- name: babysit-loop -description: "Run one repository's pull-request queue as the merge lane of the loop-lane three-session topology: a self-paced standing or drain loop that invokes /source-control:babysit-prs each cycle at the resolved autonomy tier, layered with an activity grace window, do-not-merge respect, escalation, and lane telemetry.

Merge authority is human-only until the target repo's tracked config adopts the lane; the adopted baseline is human merge for everything except gate-proven C2-mechanical PRs, and standing merge-rung raises bind only from the tracked config seam. One named exception: an invocation whose own argument line carries BOTH the 'autopilot' tier keyword AND the dedicated raise argument '--merge c3-this-run' (never a config value, never model-supplied, never inferred from a drain/merge phrasing) widens that single invocation's merge authority up to C3, with a fresh independent frontier-tier subagent resolving needs-human/thread/finding blockers first — C4-structural and C5-untrusted-provenance stay unconditionally human-merge regardless, and 'autopilot' alone leaves merge authority at the tracked rung.
