sharpen

sharpen is a skill for Claude Code, Codex from vladolaru/claude-code-plugins. It costs 19 tokens per session (2,208 once invoked), scanned A, original, MIT.

A review tool that examines how an agent worked during a conversation and records concrete ways to improve its process.

In plain words
What is it for?
It helps document better working methods for coding agents and capture process improvements as project knowledge.
Why use it?
It helps identify repeated inefficiencies without relying on memory or informal feedback.

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.

Security

Grade A, and why

sharpen 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 4d 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 — 207 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:

  1. Treat the text supplied after the skill mention as the invocation arguments. Substitute that exact text for ${CODEX_SKILL_ARGUMENTS} before executing shell commands.
  2. Resolve CODEX_PLUGIN_ROOT to 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 this SKILL.md.
  3. Assign both variables explicitly in any shell call that uses them. Codex does not export these instruction variables automatically.
  4. Use Codex's available user-input and subagent tools when the workflow requests them.
  5. Follow the canonical workflow below without skipping its gates or artifact checks.

Canonical Workflow

$dex:sharpen

Analyze agent behavior in the current conversation, find inefficiencies, and capture concrete fixes as project knowledge. This is an operational extraction strategy - it captures how the agent should work, not domain knowledge about the codebase.

What ships with it

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.

sharpen is a skill published in the GitHub repository vladolaru/claude-code-plugins (8 stars, last pushed today), licensed MIT. It adds 19 tokens to every session and 2,208 once invoked, about $0.0001 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 2026-08-31.
