instructions

instructions is a skill for Claude Code from geniro-io/geniro-claude-harness. It costs 111 tokens per session (5,191 once invoked), scanned A, a copy of geniro-instructions, Apache-2.0.

A system for creating, editing, validating, listing, and deleting custom instructions for coding-agent work. It supports rules for specific workflow phases, shared coding practices, and read-only sources used to verify facts.

In plain words
What is it for?
Use it to manage project instructions, add phase-specific guidance, define shared code-style rules, or document what checks do and do not verify.
Why use it?
It keeps agent behavior rules in one managed place and helps ensure they are valid and not overstated. The rules can guide both specialized tasks and recurring code-writing or review steps.

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

instructions scanned grade A with 1 finding 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.

Asks the agent to reveal its instructionslowSystem prompt leakage

Directions to print, repeat or translate the system prompt extract configuration the operator did not intend to expose.

argument-hint: "[what you want — e.g. 'add a rule to run tests', 'show instructions', 'delete review rules']"

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

How it starts

The opening of the file, as written. The whole thing — 180 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Instructions: custom instruction management

Contents

  • Loop invariants
  • Anti-rationalization
  • Definition of done
  • Budgets — quality-first
  • ACI per-phase tool surface
  • Memory I/O
  • Termination case → state mapping
  • Valid scope set
  • File shapes
  • Frontmatter field reference (review-extra/<slug>.md)
  • Phase 1 — parse intent, resolve scope, dispatch to a mode
  • Writing effective instructions
  • Cross-references

Stateless loop: Parse → Execute → Done — every invocation is a single transaction with no state file. CRUD frontend over .geniro/instructions/ — the L4 procedural memory layer. Five modes: list, create, edit, validate, delete; Phase 1 resolves exactly one of them per invocation.

Phase body. Phase 1's Steps live in ${CLAUDE_PLUGIN_ROOT}/skills/instructions/phase-1-parse.md. Read it on entry to the phase, and again on any resumption of it, including after a compaction. That Read is the phase's physically-first action and carries a one-line echo, per ${CLAUDE_PLUGIN_ROOT}/skills/_shared/phase-entry-read.md — the phase file holds this skill's gates and its helper call sites, so work started before the Read runs outside them. A create/edit run also reads ${CLAUDE_PLUGIN_ROOT}/skills/instructions/phase-1-block-type-reference.md from there.

Mode bodies. Each mode's Steps live in ${CLAUDE_PLUGIN_ROOT}/skills/instructions/mode-<op>.md. Read the one Phase 1 dispatches to, and again on any resumption of it — the four it did not dispatch to are never read. That Read comes before any step of the mode and carries a one-line echo, per ${CLAUDE_PLUGIN_ROOT}/skills/_shared/phase-entry-read.md — the dispatched body is this run's phase body, and it holds every pause this skill declares today, not a cap on future ones. delete is where that matters most: mode-delete.md is the sole home of the destructive-op confirmation, and the .geniro/ deletion guard hook permits a per-file rm -f on .geniro/instructions/<scope>.md, so nothing else stops it.

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.
