instruction-placement

instruction-placement is a plugin for Claude Code from melodic-software/claude-code-plugins. Its manifest loads nothing; the 3 skills it bundles cost 554 tokens per session together, scanned A, original, MIT.

An instruction-management toolkit that audits where coding-agent guidance is stored and proposes moving it to the surface that loads it at the appropriate time.

In plain words
What is it for?
Use it to audit instruction placement, classify findings, validate destination patterns, and maintain an index of deferred rules.
Why use it?
It prevents rules meant for one folder or file type from affecting the whole repository, and prevents important instructions from sitting in documents the agent does not automatically read.

Security

Grade A, and why

instruction-placement 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 yesterday.

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.

The audit skill sweeps a repository's instruction layer and its ordinary markdown for content whose scope is narrower than the surface carrying it \u2014 conventions keyed to one file type or one subtree sitting in an always-loaded CLAUDE.md or AGENTS.md \u2014 and for normative conventions stranded in documentation Claude never loads at all, then classifies each against a routing rubric and proposes a destination whose `paths:` glob is machine-validated before it is ever offered. Safety-class content (irreversible actions, secrets, data integrity, external publication, compliance, agent authority) is hard-denied from demotion and reported as held back rather than proposed, because demotion trades guaranteed presence for conditional presence and deferred surfaces are invisible inside subagents and absent after compaction until re-triggered. Every accepted move regenerates an always-loaded index of deferred surfaces, which is what keeps a demoted rule reachable from a subagent that never receives its injection. The audit is read-only and emits a diffable findings artifact; realignment is a separate skill gated per item with no blanket-approve path; a deterministic check skill gates that every rule glob still resolves and the index is current; and a setup skill verifies the one thing no other gate can see \u2014 that the index target is a file Claude Code will actually read, since it reads CLAUDE.md and not AGENTS.md.",

What it installs

The manifest is a name and a version. 3 skills travel with it, and installing the plugin installs all of them — 554 tokens a session between them. Each is measured on its own page, and each can be installed alone.

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.
