What is axiom-verification?

A completion-checking rule for coding tasks. It requires the agent to test the original problem again before saying a fix is done.

Use it when fixing bugs, changing a user interface, or running a database migration. It helps repeat the failing test or real user steps and check the result.

It prevents untested fixes from being presented as complete. It also makes the agent state clearly when it could not verify the result.

axiom-verification — Skill for Claude Code and Codex by Team-Deepiri

Install

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.

Any agent

npx skills add Team-Deepiri/deepiri-axiom --skill axiom-verification

Clone the repo

git clone --depth 1 https://github.com/Team-Deepiri/deepiri-axiom

Made for: Claude Code, Codex.

Per session 29 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.

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 5.1	$0.00029	$0.00153
Opus 5.5	$0.00012	$0.00061
Sonnet 5.5	$0.00006	$0.00031
Haiku 4.5	$0.00003	$0.00015

Security

Grade A, and why

axiom-verification 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.
