Skill Claude CodeCodex
Splits scope into a product-first work breakdown that follows the 100% rule, keeps pieces from overlapping, uses outline numbers, and gives every piece a dictionary entry. Use when an epic, feature, or new subsystem needs a clean split into deliverables, or one source of truth before folders or work begin. Do not use…

Skill Claude CodeCodex
Prepares focused context for an AI agent, reviewer, verifier, or releaser at the start of a task, with a clear role, goal anchor, authority, evidence to produce, forbidden actions, and stop conditions. Use when an agent or reviewer is about to begin work and needs bounded context before it starts. Do not use for a…

Skill Claude CodeCodex
Reviews public text for license, warranty, compliance, safety, security, certification, and fitness claims that go too far, then rewrites them to stay inside the real limits. Use when shipping or editing public docs, READMEs, or rollout copy. Do not use for internal code comments, or for deciding actual legal fitness…
FlyFission/nuclear-grade-context-engineering
Skill Claude CodeCodex
Records a ship, block, defer, or ship-with-risk decision that ties baseline, evidence status, residual risk, rollback, monitoring, and handoff together. Use when a packet, PR, release, dependency change, or agent-authority change approaches merge. Do not use early in development before evidence exists.
FlyFission/nuclear-grade-context-engineering
Skill Claude CodeCodex
Checks that the way you cite source families, agencies, standards, or borrowed ideas is honest and does not claim too much. Use when public docs, templates, skills, change records, or rollout copy point to outside sources. Do not use for private notes, or for checking whether code actually works.
FlyFission/nuclear-grade-context-engineering
Skill Claude CodeCodex
Screens what a controlled change might leave out of date across docs, tests, skills, commands, templates, checkers, prompts, releases, saved versions, and evidence, and names the triggers to re-check. Use when a change touches a controlled item. Do not use for a single edit that nothing else depends on.
FlyFission/nuclear-grade-context-engineering
Skill Claude CodeCodex
Decides which code, prompts, models, tools, dependencies, docs, tests, evals, releases, or claims need their approved state tracked. Use when scoping what a change puts at risk or what must stay reviewable. Do not use for scratch work that nothing else depends on.
FlyFission/nuclear-grade-context-engineering
Skill Claude CodeCodex
Brings an abandoned or half-filled change packet to an honest terminal state by completing it, closing it with a recorded rationale, or deleting it. Use when ng status flags a scaffold or invalid packet, a long session left a draft behind, or work was abandoned mid-packet. Do not use for an actively in-progress…
FlyFission/nuclear-grade-context-engineering
Skill Claude CodeCodex
Creates or updates Quick or Standard change records, adds the required files, and refreshes what each claim must prove for an evidence-backed pull request. Use when starting or revising a change record. Do not use for a one-off throwaway script, or for work that belongs in an existing record rather than a new one.
FlyFission/nuclear-grade-context-engineering
Skill Claude CodeCodex
Decides who holds authority for a change — the agent at the edge or a human gate — by matching decision rights to reversibility, evidence, and consequence, and names the escalation trigger. Use when an agent could act on something irreversible, trust-bearing, or thinly evidenced. Do not use for trivial reversible…
FlyFission/nuclear-grade-context-engineering
Skill Claude CodeCodex
States what an agent intends to do and why before a critical or irreversible action, so a reviewer can challenge the thinking and not just the result. Use before deploys, migrations, public claims, or trust changes that deserve a stated intent, expected result, abort criteria, and backup. Do not use for routine…
FlyFission/nuclear-grade-context-engineering
Skill Claude CodeCodex
Checks a critical agent action against its exact target, expected result, and stop condition before and after execution. Use when an agent is about to make a critical edit, run a command or migration, use a credential or tool, change a dependency or model, make a public claim, or affect a release. Do not use for…
FlyFission/nuclear-grade-context-engineering
Skill Claude CodeCodex
Hands off unfinished work with a closed-loop briefing of state, changed conditions, remaining scope, authority limits, and open evidence. Use when AI-agent, reviewer, verifier, releaser, or resumed-thread work transfers to a new owner. Do not use when the same owner continues uninterrupted with full context.
FlyFission/nuclear-grade-context-engineering
Skill Claude CodeCodex
Turns incidents, near misses, bad handoffs, review surprises, escaped bugs, and signals from real use into lasting fixes to your safeguards. Use after something went wrong or nearly did and a future safeguard should change. Do not use during a live incident, which comes first, or to blame someone.
FlyFission/nuclear-grade-context-engineering
Skill Claude CodeCodex
Designs a clean folder and file layout as real architecture, building it from a work breakdown or an existing tree, grouping by what changes together and what happens to it, with platform-safe sortable names and a short note per folder. Use when laying out a repo or agent workspace, deciding where a file belongs, or…
FlyFission/nuclear-grade-context-engineering
Skill Claude CodeCodex
Builds claim-to-evidence trace rows with statuses, gaps, tests, evals, reviews, and narrower non-claims. Use when a packet asserts something a reviewer must trust. Do not use to make the final ship decision, judge public legal wording, or invent evidence that does not exist.
FlyFission/nuclear-grade-context-engineering
Skill Claude CodeCodex
Challenges the assumptions behind a change before an agent builds, merges, or releases, and names the one fact that would change the decision. Use when a request, plan, diff, dependency, agent action, public claim, or release is vague, high-stakes, or easy to talk yourself into. Do not use for a tiny, obvious…
FlyFission/nuclear-grade-context-engineering
Skill Claude CodeCodex
Picks Quick, Standard, or a stronger human-reviewed mode based on consequence, how easy it is to undo, and how much is unknown. Use when you start a change to code, docs, dependencies, AI power, releases, or public claims and the right level of care is unclear. Do not use for a tiny easy-to-undo edit with obvious…
FlyFission/nuclear-grade-context-engineering
Skill Claude CodeCodex
Records the version everyone agreed is correct, the evidence behind it, and what would make that record out of date. Use when a standard change ships, when prompts, models, tools, dependencies, docs, or release items are accepted, or when a lesson forces a re-record. Do not use for a tiny local edit with nothing to…
FlyFission/nuclear-grade-context-engineering
Skill Claude CodeCodex
Captures an agent run's tool calls, decision points, inputs, outputs, token use, and approval steps as a clear, repeatable record linked into the packet trace and verification record. Use when how the agent got there matters for debugging, auditing, cost review, or defending a release decision. Do not use for a…
FlyFission/nuclear-grade-context-engineering
Skill Claude CodeCodex
Routes a defect found in a shared or supplied artifact (a shared prompt, skill, dependency, model, eval, or template) to the downstream teams, agents, and releases that depend on it, not just a local fix. Use when a discovered defect affects others who consume the same artifact. Do not use for a defect local to your…
FlyFission/nuclear-grade-context-engineering
Skill Claude CodeCodex
Runs a live incident the stabilize-first way — name a commander, separate facts from hypotheses, prefer reversible actions, communicate on a cadence, and drive corrective actions to closure. Use when production is broken, data is at risk, or an agent action caused harm. Do not use for routine non-incident work, or as…
FlyFission/nuclear-grade-context-engineering
Skill Claude CodeCodex
Reviews a diff or module for slipping standards, favoring deletion over rearranging, and ends in one honest verdict. Use when a change risks oversized files, needless layers, feature logic leaking into shared code, or clever indirection. Do not use for a trivial obvious edit, or for a check that is only about whether…
FlyFission/nuclear-grade-context-engineering
Skill Claude CodeCodex
Tests the current work against a written, lasting mission anchor and forces one choice, re-anchor, escalate, or stop. Use when an agent keeps finishing tasks but the work drifts from the goal, scope creeps, the same action repeats in a loop, or standards slip one small step at a time. Do not use for a tiny edit with…
