lid-coach is a skill for Claude Code from jszmajda/lid. It costs 117 tokens per session (11,415 once invoked), scanned B, original, MIT.

An advisor that reviews how a project uses linked-intent development, a method for connecting intended behavior with implementation, and writes recommendations.

In plain words
What is it for?
Use it to inspect a project's linked-intent development practices and produce a prioritized improvement report; it does not edit files.
Why use it?
It identifies where the project differs from that method's principles or misses opportunities to use them better.

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 B, and why

lid-coach scanned grade B 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 10d 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.

Strips warnings and disclaimersmediumAnti-refusal

Omitting safety caveats hides risk from the user and is a common jailbreak preamble.

The knowledge base for these conversations lives in `references/lid-faq.md`. **Load that file on demand** when the user's prompt looks like an adoption / pattern / how-do-I question, draw on its framings, and answer in y

How it starts

The opening of the file, as written. The whole thing — 342 lines — stays where its author put it; the contents beside it link to each section on GitHub.

LID Coach

Reviews a project's current LID usage against LID's own principles and produces a prioritized set of recommendations. The posture is advisory: the project works; this skill tells the user where patterns are drifting from LID's principles or leaving value on the table.

This skill is invoked only by the /lid-coach command. It does not auto-trigger — a principle review reads a broad slice of the project and would be wasteful to fire opportunistically.

What this skill is not

  • Not a configuration reconciler. That is /update-lid. When a finding implies a configuration change, point the user there.
  • Not a structural auditor. That is /arrow-maintenance (when the overlay is installed). When a finding is structural in nature — orphans, reverse orphans, adjacent-level coherence, index.yaml drift — surface the pattern and recommend /arrow-maintenance for the precise enumeration. Do not attempt to enumerate structural instances from sampled reads.
  • Not a file editor. Advisory posture is load-bearing. Produce the report; the user applies.

Dispatch

On invocation, inspect the project and take exactly one of these actions:

Detected state Action
No instruction file (the project's AGENTS.md, or CLAUDE.md under Claude Code) and no LID-shaped artifacts anywhere in the project (no HLD, no LLDs, no specs, no arrow overlay) Inform the user the project is not LID-configured; recommend /update-lid. Do not proceed with coaching.
The instruction file absent or missing LID directives but the project has LID-shaped artifacts (see threshold below) Proceed with a full review anchored on the existing artifacts (default Full mode). Surface the missing (or precursor-named) instruction-file directives as a high-priority finding recommending /update-lid to reconcile. Do not refuse — a project with a populated arrow is LID-shaped regardless of whether the instruction file has caught up with the directive naming.
LID directives present, but docs/intent/ or docs/high-level-design.md is missing Proceed with a reduced review of what exists. Surface each missing piece as a high-priority finding and recommend /update-lid to reconcile.
Scoped mode with missing or empty ## LID Scope Surface the misconfiguration as a high-priority finding. Run a conservative project-wide review treating all paths as in-scope.
docs/arrows/index.yaml present but cannot be parsed Flag corruption to the user before any principle review. Offer either to proceed with a reduced review treating the overlay as absent, or to pause for the user to repair.
Fully configured (directives + mode marker + standard directories; Scoped with valid scope) Proceed with a full review.

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.
