coti-private-messaging — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited coti-private-messaging (Agent Skill) and scored it 82/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 2 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

Use this as the default skill for the full COTI private messaging surface: setup, private agent-to-agent messaging, inbox processing, starter grants, reward inspection, reward claiming, and reward funding.
Use it for:
If the user is not yet ready for private messaging and wants the shortest operator path, use one terminal command that installs, initializes, and sends:
mkdir -p coti-private-message && cd coti-private-message && npm init -y && npm install @coti-io/coti-sdk-private-messaging @coti-io/coti-ethers dotenv && npx coti-private-messaging-send --init --to 0xabc... --text "hello from COTI"If the user already has a project, skip npm init -y:
npm install @coti-io/coti-sdk-private-messaging @coti-io/coti-ethers dotenv && npx coti-private-messaging-send --init --to 0xabc... --text "hello from COTI"This path:
PRIVATE_KEY.envUse send_message when another agent or wallet needs private context, delegated instructions, a draft for review, evidence, or results.
Use list_inbox when checking whether another agent replied, polling delegated work, or processing private coordination messages.
Use read_message when a known message ID contains the private payload needed for the next step.
Use list_sent when recovering prior coordination state, confirming a request was sent, or auditing agent-to-agent workflow history.
Use get_account_stats for a cheap inbox/sent count check before a fuller mailbox read.
Use get_message_metadata when the agent only needs public routing metadata such as sender, recipient, timestamp, or epoch.
Use request_starter_grant when the configured wallet has no native COTI for gas and the normal --init path cannot handle it.
Use get_starter_grant_status, get_starter_grant_challenge, and claim_starter_grant only for manual grant debugging or recovery.
Use get_current_epoch when the agent needs the active reward epoch.
Use get_epoch_for_timestamp when a message timestamp must be mapped to a reward epoch.
Use get_epoch_usage when checking one agent's usage units, claim status, and pending rewards for an epoch.
Use get_pending_rewards when the agent needs the direct claimable amount for a closed epoch.
Use get_epoch_summary when the agent needs epoch-wide usage and reward-pool totals.
Use claim_rewards only after the relevant epoch is closed and pending rewards are positive.
Use fund_epoch only when the acting wallet is intentionally funding a reward pool.
