What is pi-lens AGENTS.md?

Repository instructions for pi-lens, a coding-agent extension that runs checks on changed files and collects diagnostics from language tools and command-line programs. They also define task routing, design rules, and testing requirements.

Use them when changing or reviewing pi-lens code, including its language-tool integration, runners, installers, cache, sessions, telemetry, or review features.

They keep work consistent with the repository's contracts and direct the agent to the right rules and tests. They also prevent it from guessing how the agent software development kit works.

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	$0.17403	$0.17403
Opus 5.5	$0.06961	$0.06961
Sonnet 5.5	$0.03481	$0.03481

Security

Grade C, and why

pi-lens AGENTS.md scanned grade C 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 2d 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.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

How to use this file

Read order: the engineering principles (every harness here carries a verbatim copy in its global instructions; vendored at docs/engineering-principles.md, never hand-edited), then this file, then the role contract for the task. This file holds only what is specific to pi-lens and wins on conflict. Dated incidents and closed decisions live in HISTORY.md.

The principles, one line each, linked to their section of the vendored file. The vendored file wins on any difference from this digest.

Premise first: reproduce the defect through the production call path before the fix (§1 Building).
Speculative robustness needs buy-in: no new mechanism for an unreproduced race or edge case without the trigger path, evidence, cost and a maintainer decision (§1 Building).
Climb the minimalism ladder: reuse an existing seam before adding a line (§1 Building).
Net-count rule: a new shared helper deletes a same-shape sibling in the same change (§1 Building).
Sweep the pattern, not the instance, and record the consolidation verdict (§1 Building).
Design shared state once, before a second writer joins (§1 Building).
Give every new failure path one bounded, observable record (§1 Building).
Diff the blast radius as a call tree, with +/- on moved lines (§1 Building).
Red first, and paste the failing transcript (§2 Testing).
Ship the tests in the same commit as the code (§2 Testing).
Quote each mutation's red; a ticked box with no transcript is false (§2 Testing).
No tautological test: assert an independent effect through the real seam (§2 Testing).
Close only when every criterion is met; otherwise Refs and post the remainder (§4 Honesty and records).

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.
