place

place is a skill for Claude Code from jongwony/epistemic-protocols. It costs 44 tokens per session (8,047 once invoked), scanned A, original, MIT.

A read-only audit that assigns every clause in language-model instructions to an appropriate destination. It preserves operational details such as conditions, thresholds, and actions instead of judging a file only by its length.

In plain words
What is it for?
Use it to review instruction files and decide where each rule, explanation, example, or constraint should live.
Why use it?
It helps explain why instruction files keep growing and finds rules buried inside surrounding rationale. It also considers whether examples distract attention or anchor the model to one case.

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

place 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 6d 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.

How it starts

The opening of the file, as written. The whole thing — 215 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Placement Audit

A read-only audit of LLM-facing instruction prose that answers one question per clause: where does this belong? Every routing unit receives a destination, whether or not it bears a decision, and a pass that did not reach every unit reports that instead of reading as a finished audit. The audit emits routes; the human author applies them.

Purpose

Instruction surfaces accumulate. The usual review asks whether a file is too long and answers by cutting, which loses the operative clauses buried inside rationale — a threshold, a condition, a named action, sitting in the middle of a paragraph that exists to explain something else. Routing preserves them: content that leaves a surface arrives somewhere, and the clause that has to keep binding behavior is rewritten to stand on its own before the paragraph around it moves.

The audit also takes up two judgments that were previously made separately — whether a mention holds attention on something the instruction is trying to avoid, and whether an example anchors the model to one instance. They enter on different footings. Which kind an example is argues for a destination, so that judgment is a placement question and an example is decided by which surface it belongs on. Whether a prohibition should be restated positively is not: it changes how the clause is written wherever it lands, and the destination steps settle placement without it.

Inputs

Manual invocation only (interactive /place):

  • The caller passes target file paths or a glob; with no argument, the audit enumerates the in-scope set under the working tree. The target bounds which routing units receive routes; it does not bound where a pointer at one of them may live.
  • The reference-search boundary is the in-scope surface set under the working tree unless the caller supplies a narrower one. It is named in the report, because a result found inside a boundary supports a claim about that boundary and never that nothing exists outside it.
  • Files are read at their working-tree state — the post-edit, pre-commit content the author is about to ship.

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.

place is a skill published in the GitHub repository jongwony/epistemic-protocols (160 stars, last pushed today), licensed MIT. It adds 44 tokens to every session and 8,047 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
