_shared

_shared is a skill for Claude Code, Codex from kalpmodi/akira. It costs 56 tokens per session (212 once invoked), scanned A, original, MIT.

A shared set of Bash functions used internally by other Akira security skills. It manages session state, shared findings, memory, and status signals.

In plain words
What is it for?
Supporting other Akira skills as they read shared data, write progress information, and emit signals.
Why use it?
It gives the skills a common way to exchange information and track progress. It is not something you invoke directly.

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

_shared 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.

The scan reads SKILL.md. This mod also ships 2 executable files (phase0.sh, signals.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

What it actually says

Shared Utility Library

This directory contains bash libraries sourced by all Akira skills. It is not an invokable skill.

Files

  • phase0.sh - canonical Phase 0 functions: p0_init_vars, p0_state_gate, p0_read_relay, p0_read_memory, p0_read_hypotheses, p0_manifest_write, p0_relay_write, p0_completion_gate
  • signals.sh - atomic append-only signal emission: emit_signal TYPE VALUE SOURCE CONFIDENCE

Usage

source ~/.claude/skills/_shared/phase0.sh
source ~/.claude/skills/_shared/signals.sh
Files

What ships with it

2 files 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.

Changes

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.
