What it does
Grammarly License Governor is an agent skill from jeremylongshore/tons-of-skills-marketplace. Produce a review-only plan from a sanitized Grammarly License Management snapshot, identifying non-admin users whose last activity is before an explicit cutoff. Use when governing unused seats without exposing identity data or mutating Grammarly. Trigger with "review Grammarly inactive licenses", "Grammarly seat audit", or "analyze a sanitized Grammarly license snapshot".
Its SKILL.md is about 1.5k 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/license-management-contract.md` and `references/snapshot-schema.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.
When your agent uses it
- Governing unused seats without exposing identity data
- Mutating Grammarly
- With review Grammarly inactive licenses
- Grammarly seat audit
Example prompts
- “review Grammarly inactive licenses”
- “Grammarly seat audit”
- “analyze a sanitized Grammarly license snapshot”
- “/grammarly-license-governor”
Requirements
- Python 3
- Compatibility (from SKILL.md): Agent Skills-compatible hosts; requires Python 3.10+
- Pre-approved tools (allowed-tools): Bash(python3:*)
Workflow steps
3 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
Bash(python3:*)
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
python3
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
developer.grammarly.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Compatibility
Agent Skills-compatible hosts; requires Python 3.10+
From compatibility in the SKILL.md frontmatter.
Context cost
Grammarly License Governor loads about 1.5k tokens when it runs, and up to ~2.7k if it reads all its reference files. Until then it costs about 100 tokens; SKILL.md has 630 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.
Safety
Auto-check passed
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.

Grammarly License Governor
This skill creates a human-review queue from a sanitized License Management API
snapshot. It never calls Grammarly, resolves identities, sends a mutation, or
deletes a user or invitee. A candidate is only a non-admin user whose recorded
last_activity_at is strictly earlier than the explicit inactive_before cutoff.
Overview
Use this skill for a bounded seat-review decision from sanitized user activity metadata, not for identity resolution or live account administration.
Prerequisites
No credentials, network access, Grammarly account, names, email addresses, or raw IDs are needed. Python 3.10+ is the only runtime requirement. If a separate live integration is being designed, consult the official OAuth 2.0 credentials documentation (accessed 2026-09-04) for scopes; live authentication and mutation are outside this skill.
Instructions
Step 1: Run the analyzer
python3 scripts/analyze_license_snapshot.py snapshot.json
cat snapshot.json | python3 scripts/analyze_license_snapshot.py -
python3 scripts/analyze_license_snapshot.py --self-testThe input contract is intentionally narrow. It accepts one snapshot object with an explicit snapshot timestamp and UTC cutoff, producer attestation for keyed HMAC-SHA256 pseudonymization, and records containing only resource pseudonyms, last-activity timestamps, and the admin flag. Names, email addresses, raw numeric/string IDs, institution identifiers, secrets, tokens, headers, and unknown fields fail closed, including when nested.
Step 2: Apply the review rules
- Require
snapshot_generated_atandinactive_before; never use the current time or an implicit default, and reject a cutoff later than the snapshot. - Compare timestamps in UTC and classify only
last_activity_at < inactive_before. Equal timestamps are not inactive-before evidence. - Exclude every record with
is_admin: true. The official API says admin licenses cannot currently be removed; admins must not enter the candidate plan. - Require the exact producer-attestation object and keep candidate identity to
resource_id_hmac_sha256, generated outside this tool with an organization-controlled HMAC key. The analyzer validates attestation and digest shape but cannot cryptographically prove upstream generation. Do not reverse, join, enrich, or display identity attributes; a plain unsalted hash is not enough. - Emit
HUMAN_REVIEW_ONLYcandidates. The output is not an execution manifest and contains no delete operation, endpoint call, or authorization instruction. - Missing activity evidence, duplicate digests, malformed timestamps, and raw or identity-bearing fields are review blockers, not reasons to guess.
Invitees are outside this analyzer's inactivity rule because the documented invitee
shape has creation and invitation status, not last_activity_at. Keep them in a
separate human review if they need governance; do not silently treat an invitee's
creation date as inactivity.

Step 3: Stop on the unresolved official path conflict
The official License Management API page gives two different paths for the institution
summary: its endpoint heading says /ecosystem/api/v1/institutions-summary, while its
example request omits /v1 and uses /ecosystem/api/institutions-summary. This is
unresolved documentation evidence. Treat it as a fail-closed stop: verify the path
with Grammarly before any human-authorized integration work. This skill does not
automate that endpoint and the offline script never performs network access.
Read the focused references when needed:
references/snapshot-schema.md— exact sanitized input and review-plan output schema.references/license-management-contract.md— official user/admin/invitee facts and the preserved path conflict.
Output
The script emits plan_type: REVIEW_ONLY, mutation_performed: false, snapshot time,
cutoff, the bounded producer-attestation claim, counts, and sorted candidates containing
only pseudonyms and the HUMAN_REVIEW_ONLY action. It never emits names, emails, raw
IDs, or a delete request.
Error Handling
Invalid JSON, missing or implicit cutoff, non-UTC timestamps, malformed or duplicate digests, admins with missing fields, forbidden identity/secret keys, and unknown fields fail closed with a non-zero exit. No partial candidate plan is emitted.
Examples
- A non-admin active before the cutoff becomes a review candidate.
- An admin with the same old activity is counted as excluded and never becomes a candidate.
- An invitee is not classified from
created_at; its activity evidence is absent. - Either institution-summary path variant stops live integration work for human verification; the offline analyzer does not select one.
