Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00042 | $0.02746 |
| Opus 5 | $0.00021 | $0.01373 |
| Sonnet 5 | $0.00008 | $0.00549 |
| Haiku 4.5 | $0.00004 | $0.00275 |
Grade A, and why
send scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 331 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Intent
Send a message, event, or payload to an external destination with full policy enforcement, approval gates, and audit trail. This capability handles external side effects that cannot be undone.
CRITICAL: This capability requires explicit user approval before execution.
Success criteria:
- Message delivered to destination successfully
- All policy constraints verified before sending
- Approval gate passed (explicit user confirmation)
- Complete audit trail of what was sent
- Delivery confirmation obtained where possible

message |
Yes | object | Payload to send |
protocol |
Yes | string | Communication protocol (http, grpc, smtp, amqp, etc.) |
approval_token |
Yes | string | Token confirming user approved this send (MANDATORY) |
checkpoint_ref |
Yes | string | Reference to checkpoint before send (MANDATORY) |

No | object | Retry configuration on failure |
Procedure
-
Verify approval: Confirm explicit user approval exists
- Check
approval_tokenis valid and recent - BLOCK send if approval is missing or expired
- Log approval verification for audit
- Check
-
Verify checkpoint: Confirm recovery point exists
- Validate
checkpoint_refreferences valid checkpoint - BLOCK send if checkpoint is missing
- External sends are irreversible - checkpoint is for state recovery
- Validate
-
Validate destination: Ensure target is permitted
- Check destination against allowlist if defined
- Verify destination format matches protocol
- Block sends to disallowed destinations
-
Apply constraints: Enforce policy limits
- Check rate limits have not been exceeded
- Verify message size within bounds
- Validate message format against schema
- Apply

What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

send is a skill published in the GitHub repository synaptiai/agent-capability-standard (4 stars, last pushed 3d ago), licensed Apache-2.0. It adds 42 tokens to every session and 2,746 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
