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 | $0.00026 | $0.00249 |
| Opus 5 | $0.00013 | $0.00125 |
| Sonnet 5 | $0.00005 | $0.00050 |
| Haiku 4.5 | $0.00003 | $0.00025 |
Grade A, and why
backend-safety 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 11d 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
Backend Safety
Metadata
- Version: 1.0.0
- Triggers: Backend behavior or data-boundary change
- Allowed agents: Daemon, Gatekeeper
- Side effects: May change services, schemas, migrations, or contracts
When to Use
Use for backend work beyond mechanical documentation. Apply only checks relevant to the affected boundary.
Inputs
Work packet, interface contract, domain invariants, data model, compatibility requirements, and project verification commands.
Procedure
- Identify trust boundaries, invariants, validation, authorization, and failure semantics.
- Preserve compatibility or document the approved migration path.
- Make data changes reversible where practical and protect partial-failure paths.
- Consider concurrency, idempotency, and resource limits when relevant.
- Test success and meaningful failure paths at the lowest useful layer.
Verification
Confirm contract behavior, data integrity, access control, migration safety, and relevant integration evidence.
Output
Affected contracts and data, safeguards applied, compatibility notes, verification, and residual backend risks.
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.

backend-safety is a skill published in the GitHub repository Stivi7/cyberpunk-context-runners (4 stars, last pushed 3d ago), licensed MIT. It adds 26 tokens to every session and 249 once invoked, about $0.0001 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.
