origin-confirmation

origin-confirmation is a skill for Claude Code from gosha70/code-copilot-team. It costs 41 tokens per session (2,287 once invoked), scanned A, original, MIT.

A safeguard that checks an implementation against the user's original idea before planning, building, or merging it. It uses documented origin details and approval checkpoints to detect drift.

In plain words
What is it for?
It is for validating plans, build entry, phase completion, and merges against an issue, cited source, or original user description.
Why use it?
It helps prevent a later plan or specification from quietly replacing what the user actually asked for.

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

origin-confirmation scanned grade A 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 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.

Origin-Confirmation Circuit Breaker

Before producing any plan, rubric, evaluation, build, or merge for a feature, you MUST locate and re-read the origin artifact — the user's original description of the idea — and verify that the working spec/plan/PR is a faithful realisation of it.

The latest in-repo spec.md / plan.md is not automatically the origin. Those are derived artifacts that may already be drifting. The origin lives in the issue body, external references the user has cited, and the user's own messages.

This skill is always-on. If a session derives an implementation from a derived spec without re-checking against the origin, that session has violated this skill.

Origin frontmatter convention

Every specs/<feature-id>/plan.md carries an origin: block in YAML frontmatter. scripts/validate-spec.sh enforces it.

Escape hatches

Some specs genuinely have no external origin (pure-internal cleanups, generator refactors, test plumbing). Those use the internal exemption:

origin:
  type: internal
  reason: "Refactor generator hook ordering — no user-facing behavior change."

A few legacy specs may have an origin that we cannot honestly recover. Those use the unrecoverable marker, which exits 5 from the verifier and surfaces the missing origin to anyone who touches the spec next:

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.
