improve-agent-native

improve-agent-native is a skill for Codex from jscraik/Agent-Skills. It costs 63 tokens per session (2,812 once invoked), scanned A, original, Apache-2.0.

A repository audit that checks whether AI coding agents can understand a project, use its tools, run the right checks, and recover from errors.

In plain words
What is it for?
Use it to review AGENTS.md and other instructions, assess an agent-facing product or workflow, and produce an evidence-based scorecard with specific fixes.
Why use it?
It reveals missing guidance, commands, documentation, and proof that can cause agents to drift or repeat mistakes.

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

improve-agent-native 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 8d 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.

Improve Agent Native

Produce a file-evidence scorecard for whether AI coding agents can follow repo guidance, use relevant product or workflow capabilities, run the right checks, recover from failure, and leave useful proof.

When To Use

  • The user asks if a repo, agent-facing product surface, MCP server, autonomous workflow, Claude/Copilot/Codex setup, or AI-native app is ready for agent-native work.
  • The user asks to audit repo agent compatibility, AGENTS.md quality, docs quality, missing test/build commands, proof loops, command evidence, action parity, tool design, dynamic context injection, or outcome testing.
  • A repo needs a scored gap list, specific fixes, or a keep/move/delete guidance review.
  • Agents keep drifting, skipping required evidence, using the wrong workflow, or needing the same correction.

Do not use it for broad architecture rewrites, enterprise process design, or implementation work unless the user explicitly asks to patch the repo after the audit.

Inputs

  • Target repository path or diff.
  • Whether the user wants a scorecard, recommendations only, or patch work after the audit.
  • Repo-local guidance and validation entrypoints when present.

Resolve the target, expected artifact, and edit authority from the user request, current working directory, repo-local instructions, and existing task context before asking. Ask one plain-language question only when the missing answer cannot be discovered safely and would materially change the audit.

Outputs

Preserve the user's requested comparison or reporting lanes. When the user does not specify an artifact shape, return the following scorecard schema. Whether the result is prose, a table, or YAML, preserve the target, evidence-backed strengths, severity-ranked gaps, smallest durable next moves, exact validation evidence, and residual risk.

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.
