Skill Claude CodeCodex
Use when working with the user on tasks requiring their situated knowledge — priorities, intent, energy, context the agent can't see. Describes the relational structure of productive human-agent collaboration.
Skill Claude CodeCodex
Use when investigating unfamiliar territory, narrowing possibilities through targeted questions, or diagnosing a problem by updating your own model of the situation.
Skill Claude CodeCodex
The cognitive mode of reading for what a coherent narrative left out — threads abandoned, overtaken, or never recognized as significant. Complements interpretive-synthesis (which builds the account) by interrogating what it smoothed away.
Skill Claude CodeCodex
Use when comparing expected outcomes against actual results, judging what a gap means, or evaluating whether a change achieved its intent. The review agent crystallizes this.
Skill Claude CodeCodex
Use when predicting what code looks like before reading it, anticipating where a plan will encounter friction, or forming expectations specific enough to be tested. The prepare agent crystallizes this.
Skill Claude CodeCodex
Use when building a coherent account from many observations, summarizing conversation state, or explaining how pieces connect. The skill is in what gets left out.
Skill Claude CodeCodex
Use when walking through code, documents, or changes with the user where both perspectives contribute — the agent sees structural patterns, the user sees design intent.
Skill Claude CodeCodex
Use when observations from different surfaces appear to disagree and the agent must keep each observation in its observed form before explaining causes: UI vs behavior, logs vs state, metrics vs reports, tool output vs user-visible result.
Skill Claude CodeCodex
Use when writing durable public design prose for RFCs, proposals, architecture notes, and canonization summaries where the document must serve users, implementers, maintainers, educators, and future readers.
Skill Claude CodeCodex
Background guidance for all plugin work: keep language inside the work, focus on what we're doing, and use precise and meaningful language that stays attached to the work underway.
Skill Claude CodeCodex
Use when helping the user articulate their own thinking — when they have insight they haven't fully formed, or when the task requires the user to see something the agent can point to but not resolve.
Skill Claude CodeCodex
Use when selecting among locally valid project moves by relating them to a durable project thesis, or when new evidence should revise the route while the user's situated judgment remains authoritative about what the project is for.
