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 5.1 | $0.00047 | $0.00433 |
| Opus 5 | $0.00023 | $0.00217 |
| Sonnet 5 | $0.00009 | $0.00087 |
| Haiku 4.5 | $0.00005 | $0.00043 |
Grade A, and why
sentryskills-output scanned grade A with 0 findings 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 10d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
SentrySkills Output Privacy Guard
Role
As mandatory gate before final output to prevent "explanatory answer leakage."
Input
- Text to be output
- sensitivity_state
- trust_annotations
- Whether multi-source verification completed
Output
leakage_detectedredaction_appliedconfidence_levelsafe_responseoutput_decision(allow|downgrade|block)output_rule_actionand optionaloutput_model_action
Mandatory Checks
- Credentials, keys, privacy fields
- Restatement and reconstruction leakage of sensitive context
- Whether single-source tool conclusions are over-deterministically expressed
- Multi-source verification status
Disposition Rules
- Sensitive leakage detected: redact or
block. - Multi-source verification not completed:
downgrade, output uncertainty notice. - Multi-source consistent and no sensitive leakage: can
allow. - Output rules run before output model analysis; model results may tighten but not relax rule decisions.
- Prompt-injection phrases in output text are not blocking by themselves unless they create leakage, unsafe reconstruction, or executable dangerous content.
Output Template
## Output Guard Result
- output_decision: <allow|downgrade|block>
- leakage_detected: <true|false>
- redaction_applied: <true|false>
- confidence_level: <low|medium|high>
- safe_response: <final text to user>
Recommended Script Calls
- If
trust_annotationscontains single-tool source conclusions, first call../shared/scripts/verify_multi_source_template.py. - When conclusion has not reached
multi_source_verified,output_decisionshould not default toallow.

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.

sentryskills-output is a skill published in the GitHub repository AI45Lab/SentrySkills (9 stars, last pushed 2mo ago), licensed MIT. It adds 47 tokens to every session and 433 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
