submit-suggestion - Secure GitOps Pull Request Orchestrator
This skill equips the Platform Agent to propose declarative file updates, GKE infrastructure adjustments, or configuration changes securely by committing local repository changes and submitting GitHub Pull Requests (PRs) for human review.
When to Use
- Declarative File Provisioning: Triggered when new GKE manifests or configs are requested.
- Configuration Upgrades: Triggered when upgrading version configurations, security patches, or network policies.
- Governance Policy Syncs: Triggered when compliance playbooks or settings require updates.
Crucially, you are strictly forbidden from executing direct, manual mutations. All changes must flow through a secure PR path — this skill, or the fleet-audit skill for fixes of its findings (below).
When NOT to Use
-
Fixing a fleet-audit finding. The bullets above match audit fixes too — a
security patch, a policy update — which is exactly why this warning exists. If
the change addresses a fleet-audit finding (it carries a finding id, or an
[audit] ledger issue lists that exact deviation as a finding), the
fleet-audit skill opens that pull request itself, through its remediate
subcommand — see skills/fleet-audit/SKILL.md for the invocation. That path
keys the branch on the files the fix touches, so a rerun cannot open a
duplicate: a live PR is left untouched rather than force-pushed over, and one
the harness withdrew as stale is re-proposed on the same branch. It applies
the audit labels, links the ledger, and closes the PR when the finding stops
reproducing. A PR opened through this skill gets none of that — nothing
dedupes it and nothing ever closes it, which is how one workload's findings
once became five near-duplicate PRs.
Two cautions when you take that path. remediate consumes the findings
document the audit run wrote (start prints its path); if it no longer
exists, stop and say the fix should be requested as /remediate <finding-id>
on the ledger — do not run start yourself to mint a fresh document (it
scrubs that stream's workspace, possibly under a scheduled run), and never
hand-write one. And a change a user asked for on its own terms is not an
audit fix, even when the same file appears in a ledger — this section is
about fixes of findings, not about files findings happen to mention.
Execution Instructions
Follow these steps to make, commit, and submit your GitOps suggestions asynchronously:
Step 1: Lease a Private Workspace and Branch
Never run git from wherever your shell happens to be. You share one volume with
every other agent in this pod — the fleet audits, the other kanban workers — and
a bare git checkout there lands inside a clone somebody else is mid-way
through. prepare hands you a clone that is yours alone.
The script path is spelled out from $HERMES_HOME rather than as ./skills/…
because this skill is reached from a kanban card as well as from a cron turn,
and a card dispatch starts you in the task's workspace, not the profile
directory. $HERMES_HOME is the profile directory in both. Use that form
everywhere below, including for github_token_refresh.py in Step 5.
If you do meet a No such file or directory on one of these scripts, do not
recover by writing the absolute path out: /opt/data/profiles/platform/… is
refused by the gateway lifecycle guard, under an error about restarting the
gateway that has nothing to do with what you ran. Observed live — the refusal
sent one worker on to report a change it had not made.
"$HERMES_HOME"/skills/submit-suggestion/scripts/submit_suggestion.py prepare \
--branch "platform-agent/<change_type>-<target_id>"
(Example: platform-agent/provision-mercury-09 or platform-agent/upgrade-policy-baseline)
It clones and refreshes the GitOps repository, takes the branch, and prints one
JSON line:
{
"workspace": "/opt/data/gitops/t_9f3c1e07/acme__fleet",
"lease": "t_9f3c1e07",
"branch": "platform-agent/provision-mercury-09",
"base": "main",
"repo": "acme/fleet",
"started_from": "origin/main"
}
Keep that whole line. Step 3 needs workspace and lease back. The
credential proxy refuses git add, commit, checkout, push and every other
tree-mutating verb outside a leased workspace, so a command run anywhere else
comes back as a security refusal rather than quietly damaging another agent's
work.
base is the repository's own default branch, not a hardcoded main —
started_from records what the branch was actually cut from. When the branch
already exists on the remote (Step 5, addressing feedback on an open PR),
started_from is origin/<branch> and your commits land on top of the ones
already under review. When it does not, the branch is cut fresh from
origin/<base>.
Step 2: Make and Commit the Changes
- Generate or edit the required declarative files inside the returned
workspace.
- Stage and commit the changes locally following Conventional Commit standards. CRITICAL SECURITY RULE: You must explicitly stage only the targeted declarative manifest files you generated or modified. Never use
git add . or git add -A to prevent committing transient debugging files, volatile local credentials, or workspace logs:
cd <workspace>
git add <file_path_1> <file_path_2>
git commit -m "<conventional_commit_message>"
(Example: git add config/manifest.yaml && git commit -m "feat(fleet): provision GKE operator for mercury-09" or git add policies/baseline.yaml && git commit -m "fix(policy): restrict baseline network policy ingress")
Step 3: Call the Secure Submit Suggestion Script
Invoke the same helper with submit to handle the GitHub App token exchange, git
credential configuration, branch push, and Pull Request creation. Pass both
the workspace and the lease from Step 1 — the script verifies the lease on
that tree is still yours and refuses outright if it belongs to another agent:
"$HERMES_HOME"/skills/submit-suggestion/scripts/submit_suggestion.py submit \
--workspace "<workspace>" \
--lease "<lease>" \
--branch "platform-agent/<change_type>-<target_id>" \
--title "<pr_title>" \
--body "This Pull Request was generated automatically by the **Platform Agent** control plane.
### 🚀 Functional Impact:
<detailed_markdown_bulleted_impact_description>
Please review the code diffs and merge this PR to trigger the GitOps CI/CD rollout!"
--lease is not optional bookkeeping. prepare and submit are separate
processes, and outside a kanban card there is no session identity for submit
to re-derive the lease from — so without it the script stops and tells you to
pass it, rather than inventing an id that could never match the workspace.
The script returns the clean, live GitHub PR URL. If a Pull Request for this
branch is already open, it updates that one's title and body in place and
returns its URL — resubmitting is not an error.
Step 4: Confirm Suggestion
Record the PR link returned by the script, update the pending status inside your local state registry (if applicable), and present a clean, human-readable confirmation containing the PR URL link back to the user.
Step 5: Addressing Review Feedback on an Existing PR
When you are asked to address review comments / reviewer feedback on an existing PR, read the comments yourself — never expect them pasted into the task. You have GitHub access via the minted, repo-scoped App token (cached into gh and the git credential store by scripts/github_token_refresh.py).
- Refresh auth if a call is unauthorized:
"$HERMES_HOME"/scripts/github_token_refresh.py.
- Read the PR and all its feedback — both the conversation and inline (diff) review comments:
gh pr view <PR_NUMBER> --repo <owner/repo> --json title,url,headRefName,body,comments,reviews
gh api repos/<owner/repo>/pulls/<PR_NUMBER>/comments # inline review-thread comments
- Apply the requested changes on the PR's own branch. Lease a workspace for
that branch the same way Step 1 does —
prepare --branch <headRefName> — and
work inside the workspace it prints. Because the branch already exists on
the remote, prepare bases it on origin/<headRefName>, so the commits
already under review are still there and yours go on top;
started_from in its JSON says which. Make the targeted edits, then —
following the same CRITICAL security rule as Step 2 — stage only the
specific files (never git add . / -A), commit with a Conventional
Commit message, and run submit with the same --workspace, --lease and
--branch <headRefName> so the existing PR updates in place. submit pushes
with --force-with-lease: it will update the branch your workspace fetched,
and refuse rather than overwrite one somebody else has moved in the meantime.
- Reply on the PR summarizing what changed (
gh pr comment <PR_NUMBER> --repo <owner/repo> --body "..."), then relay a clean confirmation (PR URL + what you changed) back through your kanban result.
Never ask the requester to paste the comment text — fetching it from GitHub and addressing it is your job.
