- Line 119: Update the ciphertext sanity check grep pattern to match the literal
ENC[ prefix used by SOPS output, replacing the current requirement for 32 or
more alphanumeric characters after ENC. Keep the existing file variable and head
limiting behavior unchanged.
- Around line 136-137: Update the SOPS encryption flow in
.agents/skills/cluster-sops/SKILL.md at lines 136-137 to encrypt the edited
temporary plaintext file using a path matching the repository creation rule,
then replace the original only after encryption succeeds and remove the
plaintext temporary file. Update .agents/common-operations.md at lines 178-180
to use a matching temporary filename or an explicit recipient when writing
encrypted output.
- Line 117: Update the canonical SOPS command flow containing the in-place YAML
encryption invocation to use a resolvable command, either the documented
absolute SOPS binary path or `mise exec -- sops`, rather than bare `sops`; apply
this consistently across all canonical examples in the skill.
- Around line 27-33: Correct the SOPS key-discovery guidance in both documents:
explain that SOPS 3.13.3 automatically loads SopsAgeKeyUserConfigPath beneath
getUserConfigDir(), resolving to the XDG_CONFIG_HOME or default user config
location when SOPS_AGE_KEY_FILE is unset. Keep the SOPS_AGE_KEY_FILE export as
an explicit override for keys outside that location, but remove the claim that
every SOPS call requires it.
- Around line 94-98: Update both relevant sections of the cluster-SOPS
documentation to select whichever Secret field already exists, data or
stringData, instead of assuming data. Preserve base64 values for data and plain
values for stringData, and remove the claim that SOPS converts between these
fields.
- Around line 143-144: Update the SOPS updatekeys command to use the supported
--yes and --input-type options, remove unsupported --in-place and --output-type
options, and exclude the plaintext root .sops.yaml policy from the selected
files.
- Around line 126-127: Update the decrypt/edit workflow around the sops decrypt
command and Python heredoc to create a unique mode-600 temporary file with
mktemp instead of using the fixed /tmp/<name>.plain.yaml path. Register a
cleanup trap immediately after creation so the temporary decrypted file is
removed on success and failure, while preserving the existing decrypt and edit
behavior.

Stop the workflow when decrypt or edit fails.
The canonical block does not enable fail-fast mode, chain commands, or check command status. A failed decrypt can leave $T empty or partial. A failed Python edit can leave $T unedited or partial. cp "$T" "$F" then overwrites the tracked encrypted file with that content. Add fail-fast handling before the first command.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Scope the type-flag rule to supported commands.
Trap 3 says to pass both --input-type and --output-type every time. The updatekeys section correctly says that SOPS 3.13.3 rejects --output-type. These instructions conflict and can cause an agent to reintroduce the invalid command.
Suggested wording
- **Fix:** pass both flags explicitly every time.
+ **Fix:** pass both flags for `sops encrypt` and `sops decrypt`.
+ Use the supported flags documented for `sops updatekeys`.🧰 Tools

…e-flag rule to encrypt/decrypt (updatekeys exception)
Commit c8eb55f accidentally reduced .agents/skills/cluster-sops/SKILL.md to a single PLACEHOLDER line (204 -> 1 line), which broke Markdown Lint (MD041/MD047) and made the PR body claim of a full skill untrue. Restores the file verbatim from eb21d01 (last known-good version: frontmatter, local-first workflow, key inventory, canonical flows, the three traps).
|
CI triage (Markdown Lint failure): diff-introduced. Commit |
- Add fail-fast (`set -euo pipefail`) to the change-an-existing-value flow so a failed decrypt/edit stops before `cp` overwrites the tracked encrypted file - Scope the type-flag rule to `sops encrypt`/`decrypt`; updatekeys uses its documented `--yes` + `--input-type` (rejects `--output-type`)
