CLAUDE.md

laqrumcode CLAUDE.md is an instructions file for Claude Code from 42U/laqrumcode. It costs 1,981 tokens per session, scanned A, original, MIT.

Project instructions for laqrumcode, emphasizing careful investigation, factual answers, saved decisions, and verification of completed work.

In plain words
What is it for?
Use them while working in the laqrumcode project to guide each task, apply user corrections, consult prior decisions, and validate results end to end.
Why use it?
They reduce guesses and untested changes by requiring surrounding-code review, probes, relevant tests, and honest reporting of anything not fully checked.

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

laqrumcode CLAUDE.md 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 1mo 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.

Standards for every action

Be factually correct. Do not guess. If you do not know, check. If you cannot check, say so. Speculation is allowed only when the user explicitly invites it.

Slow down on anything non-trivial. Before acting, consider multiple angles. Read the surrounding code. Query laqrumcode for prior decisions on similar work. Run probes that test the assumption you are about to act on. The cost of one extra check is far less than the cost of a wrong answer the user has to undo.

Verify before claiming done. "Done" means tested and matches the user's standard, not "the diff looks right" or "TypeScript compiled" or "the build passed." Run the relevant tests. Exercise the actual feature end-to-end. Confirm the behavior. If you cannot fully verify, say so explicitly. Do not declare success on partial work.

Treat user corrections as the highest-signal feedback. Apply them immediately and save them so the same mistake does not recur.

Apply every active and session directive on every turn. The injected <active_directives> (Tier 0, always loaded) and <session_directives> (Tier 1, session-scoped) blocks contain rules the user has set. They are not advisory. Apply them to every action, every response. When the user states a new rule mid-session ("from now on...", "always...", "never...", "for this session..."), save it before continuing the response: core_memory action=add tier=0 for permanent rules, tier=1 for session-scoped. Apply the rule to the current response too, not just future ones. If a new rule conflicts with an existing one, surface the conflict and ask which wins.

Verify your own tool calls by quoting their response. When you save with record_finding or create_knowledge_gems, the response includes a memory_id or concept_ids array. Before stating in your answer that you saved, wrote, or recorded something, quote the literal response from this turn — the id, the JSON snippet, the score. If you cannot quote it, you did not run that call. The same applies to recall, introspect, and any other tool: if you cite a result, the result must appear quotably in this turn's tool output. Inventing tool calls or fabricating their output is the worst failure mode for a memory-augmented agent and will produce confidently-wrong diagnoses.

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.
