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.

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 | $0.00072 | $0.01192 |
| Opus 5 | $0.00036 | $0.00596 |
| Sonnet 5 | $0.00014 | $0.00238 |
| Haiku 4.5 | $0.00007 | $0.00119 |
Grade A, and why
goal-loop-designer 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 9d 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 — 171 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Goal Loop Designer
Use this skill before starting a long agent loop. It turns a raw /goal or task prompt into a portable loop harness that another agent or model can execute and evaluate.
This skill designs the loop. It does not run autonomous tools, log in to providers, change repos, or approve edits.
Intake
Collect or infer the smallest useful context:
- raw goal or task prompt;
- target host: Codex, Claude Code, MiMo Code, Ollama/OpenAI-compatible, or generic CLI agent;
- repo or artifact scope;
- allowed actions and forbidden actions;
- available verification commands or manual checks;
- judge options: deterministic check, human review, Codex, MiMo Auto, local Ollama, or external LLM;
- hard limits: iterations, time, token/tool budget, file scope, network, credentials, destructive actions.
If key limits are missing, choose conservative defaults and mark them as assumptions.
Goal Critique
Before drafting the harness, critique the raw goal:
- ambiguous completion condition;
- missing non-goals;
- missing verification;
- unclear permission boundary;
- no budget or retry cap;
- self-judging without independent evidence;
- broad file or repo scope;
- hidden external dependencies;
- failure mode that would cause repeated retries.
Rewrite the goal so it is specific, bounded, and testable.
Loop Fit
Classify the work:
- single pass: one execution plus verification is enough;
- supervised workflow: multiple ordered steps, but human approval should gate progress;
- bounded loop: iteration is useful and an evaluator can decide whether to continue;
- do not loop: the work is too risky, under-specified, or unverifiable.
Prefer the lowest level that can succeed.
If a loop produces a reusable lesson, do not automatically add it to memory or a skill. Use agent-learning-layer-triage after the run to decide whether the lesson belongs in a context note, durable doc, checklist, SKILL.md, script/tool, eval, golden fixture, or rejected buffer.
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.

goal-loop-designer is a skill published in the GitHub repository markoblogo/abvx-agent-skills (16 stars, last pushed yesterday), licensed MIT. It adds 72 tokens to every session and 1,192 once invoked, about $0.0004 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 2026-08-30.
