Token cost

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	$0.00125	$0.12931
Opus 5	$0.00063	$0.06466
Sonnet 5	$0.00025	$0.02586
Haiku 4.5	$0.00013	$0.01293

Measured today against content hash 6bc047f1af7b, method: parsed. Prices are Anthropic first-party input rates as of 2026-08-30, from the pricing page.

Security

Grade B, and why

agent-loops scanned grade B 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 today.

The scan reads SKILL.md. This mod also ships 5 executable files (scripts/diff-test-audit.sh, scripts/review-provider.sh, scripts/specialist-review.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Other skills' SKILL.md files reveal prompts, capabilities and secrets that should be invisible to peers.

How it starts

The opening of the file, as written. The whole thing — 1,179 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Agent Workflow Loops

This skill defines the operational loops that implementer agents follow when making code changes and writing tests. Each loop has explicit entry criteria, exit criteria, and escalation rules. If you are an agent, follow these loops exactly.

You do not review your own work. All reviews are performed by an independent reviewer. Prefer Claude via the bundled scripts. If Claude is unavailable, use a different model before asking your own model family to review. Same-model shell-outs are the last resort. You never grade your own homework.

Bundled references:

references/testing-standards.md — Test quality standards (how to write tests)
references/audit-workflow.md — Test gap discovery (how to find what's missing)
references/perspective-catalog.md — Review perspective selection (used by primary and fallback code review)
references/review-prompt.md — Code review prompt template for fallback reviewers
references/audit-prompt.md — Test audit prompt template for module-scope (full-contract) audits
references/diff-audit-prompt.md — Test audit prompt template for diff-scope (per-commit) audits; used by diff-test-audit.sh when --git is active

Bundled scripts:

$SKILL_DIR/scripts/specialist-review.sh — Provider-aware Claude/Gemini/Codex CLI path for code review
$SKILL_DIR/scripts/diff-test-audit.sh — Provider-aware Claude/Gemini/Codex CLI path for test audit

Locate Scripts

The bundled scripts live inside the installed skill directory, not the project tree. Before invoking any script, resolve SKILL_DIR so paths work regardless of install scope:

SKILL_DIR="$(ls -d ~/.codex/skills/agent-loops 2>/dev/null || ls -d .codex/skills/agent-loops 2>/dev/null)"

All script invocations below use "$SKILL_DIR/scripts/...". Run the snippet above once at the start of your session and reuse the variable.

Architecture: Who Does What

Role	Agent	How
Implementer	Codex or Gemini	Writes code changes and test code
Code Reviewer	Claude preferred; non-self scripted fallback next; same-model provider last; fresh-context Codex final fallback	`specialist-review` keeps same-model shell-outs last; fallback reviewer uses bundled prompts and produces a review artifact
Test Auditor	Claude preferred; non-self scripted fallback next; same-model provider last; fresh-context Codex final fallback	`diff-test-audit` keeps same-model shell-outs last; fallback auditor uses bundled prompts and produces an audit artifact
Remediator	Codex or Gemini	Fixes findings from the independent review/audit artifact

Files

What ships with it

12 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.

Changes

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.

agent-loops is a skill published in the GitHub repository NickCrew/Claude-Cortex (37 stars, last pushed 2mo ago), licensed MIT. It adds 125 tokens to every session and 12,931 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it B with 1 finding (enumerates other installed skills). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
