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 | $0.00019 | $0.01071 |
| Opus 5.5 | $0.00008 | $0.00428 |
| Sonnet 5.5 | $0.00004 | $0.00214 |
| Haiku 4.5 | $0.00002 | $0.00107 |
Grade A, and why
learn 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 2mo 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 — 108 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Codex Host Adapter
This skill is generated from the canonical Claude Code command named above. To execute it in Codex:
- Treat the text supplied after the skill mention as the invocation arguments. Substitute that exact text for
${CODEX_SKILL_ARGUMENTS}before executing shell commands. - Resolve
CODEX_PLUGIN_ROOTto the absolute plugin root. The loaded skill directory is<plugin-root>/codex-skills/<skill-name>, so the plugin root is two directories above the directory containing thisSKILL.md. - Assign both variables explicitly in any shell call that uses them. Codex does not export these instruction variables automatically.
- Use Codex's available user-input and subagent tools when the workflow requests them.
- Follow the canonical workflow below without skipping its gates or artifact checks.
Canonical Workflow
$dex:learn
Capture a learning from the current conversation. Self-contained - extracts from chat history, no arguments needed. Optional focus hint narrows what to extract.
Step 1: Discover Project Infrastructure
Follow the Project Discovery steps from the knowledge-capture skill.
If .claude/docs/ does not exist, use the host's user-input mechanism:
Question: "No knowledge directory found. Create it?" Options:
- Yes, create
.claude/docs/- scaffoldslearnings/,patterns/,decisions/,research/ - Not now - abort capture
If "Not now", stop here. If "Yes", create directories with mkdir -p and continue.
Step 2: Extract Learning from Conversation
Run the <pre_extraction_analysis> from the knowledge-capture skill on the relevant conversation exchange. If ${CODEX_SKILL_ARGUMENTS} contains a focus hint, narrow extraction to that topic.
If the conversation contains nothing extractable as a learning (no discovery, fix, or gotcha), say so briefly and stop. Do not fabricate knowledge.
Following the Knowledge Extraction from Conversation guidance in the knowledge-capture skill:
What ships with it
1 file 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.

learn is a skill published in the GitHub repository vladolaru/claude-code-plugins (8 stars, last pushed 5d ago), licensed MIT. It adds 19 tokens to every session and 1,071 once invoked, about $0.0001 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 2026-08-31.
