aSPARK: Instructions file for Claude Code

CLAUDE.md

aSPARK CLAUDE.md is an instructions file for Claude Code from a-lottes/aSPARK. It costs 2,353 tokens per session, scanned A, original, MIT.

Project instructions for Claude Code, an AI coding assistant, used in the aSPARK project. They describe how to record failed checks honestly and how to avoid continuing work on an outdated branch.

In plain words
What is it for?
Use them when running project increments, verification-only checks, commits, or release preparation in aSPARK.
Why use it?
They give the assistant consistent project rules for verification, branch checks, and handing findings to the right follow-up work.

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

aSPARK 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 13d 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.

Project notes for Claude Code

Patterns worth keeping across SPARK loops, distinct from .spark/constitution.md (which holds the project's standing principles) — these are working habits.

Refuted-with-finding is a valid ceremony outcome

A verify-only sweep (or any test/verification-only feature) that finds a documented claim does not hold live should record it as refuted-with-finding, not silently pass it or fix it inline. Route the finding (verbatim quote, file:line, cause) to wherever the actual fix belongs — often a later increment, since a verify-only feature's own fence typically forbids touching the files the fix would require. A failed acceptance criterion is itself a valid, honest outcome; grinding to force a "confirmed" verdict defeats the point of verifying at all. See .spark/graph-gates-verification/evidence.md (issue #8) for the worked example.

Check branch staleness before committing a new feature's work

Before /increment starts committing, or at the latest before /go-live's pre-flight, diff the current working branch against its own merge-base with main. If the branch's prior PR already merged, cut a fresh branch off origin/main for the new feature before work piles up on the stale one — don't discover this at the last gate. /go-live for graph-gates-verification had to resolve this as a surprise; catching it earlier (e.g. at /spark's resume, or /increment's first commit) avoids the detour.

This recurred. project-kickoff's whole loop ran uncommitted, directly on local main, which let it drift 8 commits behind origin/main unnoticed — including a fully merged sibling feature touching 4 of the same files project-kickoff itself changed. /go-live's pre-flight caught it (a real 3-way merge check, zero conflicts, then rebuilding the release branch off current origin/main), but only because the rule above was re-checked live there rather than assumed clean. The sharper fix this second occurrence argues for: don't work uncommitted on main at all — commit to a real feature branch at the start of a loop's work (e.g. /story-time's first write, or /increment's first task), not only when /increment or /go-live happen to check. A branch that exists from the start can't silently drift underneath work already sitting on it.

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.
