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.

SkillSpector: 1 finding, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Rogue Agent · line 97 Skill modifies its own code, configuration, or behavior at runtime. Self-modification enables an agent to escalate privileges, disable safety constraints, or install persistent backdoors.Fix: Prevent the skill from modifying its own code, SKILL.md, or configuration files. Treat skill files as read-only at runtime.
What it costs to keep this loaded
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 | $0.00074 | $0.00959 |
| Opus 5.5 | $0.00030 | $0.00384 |
| Sonnet 5.5 | $0.00015 | $0.00192 |
| Haiku 4.5 | $0.00007 | $0.00096 |
Grade A, and why
loopops-protocol 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 6d 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.
How it starts
The opening of the file, as written. The whole thing — 161 lines — stays where its author put it; the contents beside it link to each section on GitHub.
LoopOps Protocol
Use this skill when reusable agent behavior should become more than a better prompt.
The goal is to choose the smallest durable artifact that improves future runs:
prompt -> skill -> checklist -> script -> workflow -> loop
Do not promote work upward unless the extra machinery buys reliability, reuse, or cheaper future execution.
Artifact Ladder
Classify the candidate method first:
- Prompt: one-off instruction for this run.
- Skill: compact reusable context, procedure, or tool adapter loaded on demand.
- Checklist: ordered human/agent validation sequence.
- Script: deterministic repeatable action with parameters.
- Workflow: ordered tool/process execution with gates and evidence.
- Loop: workflow plus evaluator, memory write, retry policy, and stop rule.
Prefer the lowest artifact that handles the task reliably.
Loop Suitability Gate
Promote a workflow into a loop only when all are true:
- The goal has an observable completion condition.
- Progress can be evaluated without trusting the worker agent blindly.
- A retry is likely to improve the result.
- Cost can be bounded by iteration, time, token, or tool budget.
- Failure has a clear stop, rollback, or human-escalation path.
If any condition is missing, keep it as a supervised workflow or checklist.
Open vs Closed Loop
Use an open loop when:
- the solution space is unknown,
- discovery or exploration matters,
- multiple valid approaches may exist,
- the output is research, architecture, strategy, or design direction.
Use a closed loop when:
- acceptance criteria are known,
- tests, checks, or review criteria exist,
- regression risk matters,
- the task can be decomposed into verifiable steps.
Open loops need tighter budget limits. Closed loops need stronger evaluators.
Supervisor Contract
Every loop must define:
Goal:
Completion condition:
Loop type: open | closed
Worker action:
Evaluator:
Evidence:
Memory write:
Retry policy:
Budget:
Stop rule:
Rollback or escalation:
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.

loopops-protocol is a skill published in the GitHub repository markoblogo/abvx-agent-skills (16 stars, last pushed 6d ago), licensed MIT. It adds 74 tokens to every session and 959 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-08-30.
