analyze-mini

analyze-mini is a skill for Claude Code, Codex from tmusser/ai-engineering-skills. It costs 27 tokens per session (1,101 once invoked), scanned A, original, MIT.

A conditional checkpoint for detecting when task plans, assumptions, or verification evidence are stale or inconsistent.

In plain words
What is it for?
It checks whether analysis is needed when inputs changed, requirements no longer trace cleanly to code and tests, or unresolved decisions could alter the implementation.
Why use it?
It prevents outdated reasoning from being used to make unsafe implementation decisions.

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

analyze-mini 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 9d 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.

Analyze Mini

Purpose

Prevent stale or contradictory reasoning from crossing into build-one without turning analysis into a routine gate.

analyze-mini is conditional. The cheap safeguard is an eligibility check over artifacts already being read for build or handoff. Run the full skill only when that check finds a meaningful trigger.

When to use

Run a full analysis when one or more of these are true:

  • HANDOFF.md marks analysis REQUIRED or STALE
  • task-defining inputs changed since the last FRESH analysis: SPEC.md, PLAN.md, TODO.md, scope-freeze notes, selected task, or a decision/assumption that changes implementation
  • the selected task cannot be traced cleanly from acceptance criterion to implementation slice to verification
  • an unresolved decision or assumption could materially change implementation shape
  • compatibility seams, data/metric semantics, or cross-boundary behavior create interpretation risk
  • failed verification caused the implementation strategy or plan to change
  • reconciling a stale handoff changed the live task state

Do not run a full analysis merely because the skill is installed, because a handoff is being written, or because no prior analysis exists.

Missing prior analysis is not, by itself, a trigger.

Staleness is event-driven, not time-driven. A checkpoint does not expire just because time passed.

Inputs

Use the smallest relevant set:

  • Selected task
  • SPEC.md
  • PLAN.md / TODO.md when they exist
  • Scope-freeze boundary
  • Relevant HANDOFF.md state when resuming
  • VERIFY.md when a failure or changed strategy is part of the trigger
  • Only the source files needed to resolve a specific contradiction

Passive eligibility check

Before invoking the full skill, reuse artifacts already loaded for build-one or handoff and ask:

  1. Did a task-defining input change since the last trustworthy checkpoint?
  2. Is there an unresolved decision or assumption that could change the implementation?
  3. Can the selected task still map cleanly from acceptance criterion to verification without contradicting a non-goal, spec ceiling, or scope boundary?
  4. Did a failed attempt or resume reconciliation create a new implementation uncertainty?

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.

analyze-mini is a skill published in the GitHub repository tmusser/ai-engineering-skills (4 stars, last pushed yesterday), licensed MIT. It adds 27 tokens to every session and 1,101 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
