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 | $0.00144 | $0.01779 |
| Opus 5 | $0.00072 | $0.00890 |
| Sonnet 5 | $0.00029 | $0.00356 |
| Haiku 4.5 | $0.00014 | $0.00178 |
Grade A, and why
dev_invoke_codex-cli 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 2d 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.

The opening of the file, as written. The whole thing — 266 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Invoking Codex CLI
Claude-only orchestration skill. This skill exists to let Claude delegate out to Codex CLI. It is excluded from any future shared multi-harness skill corpus.
Delegate tasks to Codex CLI using markdown files for instruction input and deliverable output. Write instructions to TASK.md, invoke Codex, then read OUTPUT.md for results.
Pattern: Markdown File Handoff
Claude Code Codex CLI
| |
+-- Write TASK.md ------------------+
| (instructions + context) |
| |
+-- Execute: codex e "Read TASK.md, |
| follow instructions, write |
| deliverables to OUTPUT.md" |
| |
| +-- Reads TASK.md
| +-- Executes task
| +-- Writes OUTPUT.md
| |
+-- Read OUTPUT.md <----------------+
| (deliverables + results) |

Benefits:
- Eliminates shell escaping issues (quotes, special characters, code blocks)
- Keeps context structured in reviewable files
- Enforces explicit deliverable format
- Supports session resume via thread ID
When to Use
Use this skill for:
- Complex implementation requiring multi-file changes
- Refactoring with dependency tracking
- Code generation with detailed specifications
- Tasks requiring extended thinking (20-30 minutes)
Model Selection
Model: Always use gpt-5.2-codex (latest model).
Reasoning Effort: Adjust based on task complexity.
| Reasoning Effort | Use Case | Speed |
|---|---|---|
xhigh |
Default. Complex tasks, deep analysis | Slowest, best quality |
high |
Medium complexity, good reasoning | Balanced |
medium |
Lighter tasks, adequate reasoning | Faster |
low |
Simple tasks, quick response | Fastest |
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.

dev_invoke_codex-cli is a skill published in the GitHub repository gpt-cmdr/ras-commander (78 stars, last pushed 2d ago), licensed MIT. It adds 144 tokens to every session and 1,779 once invoked, about $0.0007 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.

weekly-digests
Generate a serial week-by-week narrative digest of a project's full claude-mem timeline. Splits the timeline into per-ISO-week files, then runs one consecutive subagent per week — each receiving the prior week's carry-forward block — to produce one chapter per ISO week of data. Use when asked for "weekly digests"…
