grammarly-data-safety-guardianAudit and gate a Grammarly document-submission manifest offline before an authorized integration upload.
Grammarly Data Safety Guardian is an agent skill from jeremylongshore/tons-of-skills-marketplace. Audit and gate a Grammarly document-submission manifest offline before an authorized integration upload. Use when checking supported extensions, file-size and text-length metadata, approval, consent, retention, and approved destination. This skill never accepts or submits document content and is not a replacement for legal, privacy, or security approval. Trigger with "Grammarly submission preflight", "Grammarly document safety", or "Grammarly retention check".
Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including scripts and reference files (for example `eval-spec.yaml`, `references/governance-gate.md` and `references/submission-contract.md`). Compatibility notes: Agent Skills-compatible hosts; requires Python 3.10+
The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.
4 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.
Pre-approves these tools, so the agent can use them without asking each time:
Bash(python3:*)From allowed-tools in the SKILL.md frontmatter.
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
python3From the folder's file list and the shell code blocks in SKILL.md.
Hosts in commands or code, which the agent is likely to contact:
api.grammarly.comFrom URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Agent Skills-compatible hosts; requires Python 3.10+
From compatibility in the SKILL.md frontmatter.
Grammarly Data Safety Guardian loads about 1.4k tokens when it runs, and up to ~2.7k if it reads all its reference files. Until then it costs about 124 tokens; SKILL.md has 579 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

.claude/skills/grammarly-data-safety-guardian/SKILL.md (or your agent's skills folder). This skill also uses 4 other files; get the full folder from GitHub.Run a deterministic preflight over a metadata-only submission manifest. The guard answers whether a planned document upload satisfies this skill's hard safety gates; it does not read a document, contact Grammarly, create an upload URL, or retain a copy of the manifest.
The guard is a closed-world policy check for a planned document submission. It combines Grammarly's documented format and size constraints with local governance decisions while keeping the document itself outside the workflow.
Use for a Writing Score, AI Detection (Beta), or Plagiarism Detection (Beta) document submission before and after the evaluator inspects the provider-issued upload origin. The preliminary decision gates OAuth metadata disclosure; the final decision gates document bytes. Do not trigger for writing or editing content, document previews, credential troubleshooting, or a request to upload a real document.
Collect only the manifest described in references/submission-contract.md. The manifest may contain extension, byte count, optional derived text counts, and governance decisions, the pinned API control-plane origin, and the exact sanitized presigned upload origin; it must not contain text, content, previews, credentials, paths, filenames, full upload URLs, or raw API responses.
Run the guard with stdin:
python3 scripts/audit_submission_manifest.py < submission-manifest.jsonTreat BLOCKED as a hard stop. Fix the named metadata or governance decision;
never truncate or transform a document silently to pass the guard.
Treat INSPECTION_READY as permission only to create a normalized-filename job and
inspect its sanitized upload origin. Treat READY as permission to continue to the separately authorized upload
workflow, not as proof that a document is lawful, accurate, or safe for a new
destination.
The script accepts strict JSON, rejects duplicate keys and non-standard constants,
recursively rejects raw text, location, response, and credential fields, and performs
no network or filesystem writes. It enforces the documented extensions, 4,194,304-byte
maximum, UTF-8 text counts, a non-restricted classification, all approval gates, the
exact https://api.grammarly.com control-plane origin, and an explicitly approved
public HTTPS S3 presigned-upload origin on the default TLS port.
Return the deterministic JSON decision and failed check names. Do not echo a filename, path, text, preview, credential, identifier, or raw document metadata beyond the safe numeric and enum fields in the script's output.
BLOCKED is a hard stop for an unsupported extension, zero or oversized bytes,
supplied character/word limits, failed approval/consent/retention/destination
checks, unknown fields, duplicate keys, or unsafe content/credential fields. Do not
truncate, split, preview, log, or upload a document to investigate. Invalid input
returns a non-zero exit status and a JSON decision without the rejected value.

Going by SKILL.md and its folder, Grammarly Data Safety Guardian needs Python for the scripts in its folder and the command-line tools its instructions call (python3). Our summary lists: Python 3. Its frontmatter pre-approves these tools: Bash(python3:*). Compatibility (from SKILL.md): Agent Skills-compatible hosts; requires Python 3.10+.
SKILL.md names 1 domain. In commands or code: api.grammarly.com; the agent is likely to contact it when it follows the instructions. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
Grammarly Data Safety Guardian is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.4k tokens (SKILL.md is roughly 5.5k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 1.3k tokens, read only when the agent opens those files.
