specmint-core

specmint-core is a skill for Claude Code, Codex from ngvoicu/kluris. It costs 154 tokens per session (6,843 once invoked), scanned A, a copy of specmint-core, MIT.

A persistent workflow for turning feature requests into structured specifications written in Markdown. Specs live under `.specs/` and include phases, tasks, acceptance criteria, research, decisions, progress, and deviations.

In plain words
What is it for?
Use it to create or implement specs, plan features, track phases and tasks, record decisions, check status, pause or resume work, and manage one active specification at a time.
Why use it?
It gives the coding agent a durable plan and resume point instead of relying on conversation history. It also keeps the specification and its progress records aligned as work advances.

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

specmint-core 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 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.

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.

Origin

This is a copy

92% identical to specmint-core — 46 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 688 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Spec Mint Core

Turn ephemeral plans into structured, persistent specs built through deep research and iterative interviews. Specs have phases, tasks, acceptance criteria, a registry, resume context, a decision log, and a deviations log. They live in .specs/ at the project root and work with any AI coding tool that can read markdown.

Whether .specs/ is committed is repository policy. Respect .gitignore and the user's preference for tracked vs local-only spec state.

Critical Invariants

  1. Single-file policy: Keep this workflow in one SKILL.md file.
  2. Canonical paths:
    • Registry: .specs/registry.md
    • Per-spec files: .specs/<id>/SPEC.md, .specs/<id>/research-*.md, .specs/<id>/interview-*.md
  3. Authority rule: SPEC.md frontmatter is authoritative. Registry is a denormalized index for quick lookup.
  4. Active-spec rule: Target exactly one active spec at a time.
  5. Parser policy: Use best-effort parsing with clear warnings and repair guidance instead of hard failure on malformed rows.
  6. Progress tracking is sacred: After completing any task, immediately update SPEC.md (checkbox, ← current marker, phase marker) AND registry.md (progress count, date). Then re-read both files to verify the edits landed correctly. Never move to the next task without updating both files. Never end a session with the registry out of sync with SPEC.md. This is non-negotiable — if you do nothing else, do this.

Session Start

If active-spec context was injected by host tooling, use it directly instead of reading files. Otherwise, fall back to reading files manually:

  1. Read .specs/registry.md to check for a spec with active status
  2. If one exists, briefly mention it: "You have an active spec: User Auth System (5/12 tasks, Phase 2). Say 'resume' to pick up where you left off."
  3. Don't force it — the user might want to do something else first

Deterministic Edge Cases (Best-Effort)

Situation Required behavior
.specs/registry.md missing If .specs/ exists, report "No registry yet" and offer to initialize it. If .specs/ is missing, report "No specs yet" and continue normally.
Malformed registry row Skip malformed row, emit warning with row text, continue parsing remaining rows.
Multiple active rows Warn user. Pick the row with the newest Updated date (or first active row if dates are unavailable) for this run. On next write, normalize to a single active spec.
Registry row exists but .specs/<id>/SPEC.md missing Warn and continue. Keep row visible in list/status with (SPEC.md missing).
Registry and SPEC conflict Trust SPEC.md, then repair registry values on next write.
No active spec List available specs and ask which to activate or resume.

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.
