1.10.0

Added

• skills/code-craft/ is a new skill owning the shape and runtime cost of a code change, through four cuts on scope, documentation, defensive coding, and abstractions.
• code-craft also carries the runtime-cost triggers, the idiom rules, and the trust boundary that keeps minimalism off untrusted input, auth, payments, and irreversible actions.
• tools/make-badges.py merges the README badges into a single svg, since GitHub renders README images as block elements and strips inline styles, which stacks separate badges one per line. Run it after each release, as the version badge is baked into the image.

Changed

• README.md is reorganised around a banner hero, a badge strip and tables, with the installer and uninstall prompts, the manual steps, the Windows detail and the ultracode discussion folded into details blocks. Both prompts are byte-identical to 1.9.1.
• The install and uninstall steps and the "What it does" and "What's inside" tables in README.md now cover the fourth skill, code-craft, alongside test-discipline and design-fidelity.
• Over-engineering doctrine that lived redundantly across mission-control's SKILL.md, CLAUDE-md-activation.md, and the trailing line of test-discipline's Proportionality section is consolidated into code-craft, and several files now route to it by name.
• skills/mission-control/references/rationale.md drops "The pricing argument" section because its payoff-scales-with-the-tier-gap claim survives in README.md, not because the file restates it earlier.
• skills/mission-control/references/rationale.md folds "The opusplan lineage" into one sentence under History instead of keeping its own heading.
• skills/mission-control/SKILL.md drops its frontier-model framing paragraph and its four-symptom over-delivery restatement in favor of invoking code-craft, landing at 237 lines, still over the file's own ~200-line target.
• The same edit also deleted the routing-grid bullet stating "opus stays the exception", now restored as a short clause inside the "torn between two tiers" bullet.
• skills/design-fidelity/SKILL.md and README.md add code-craft to the build contract, the degradation clause, and the sibling-skill list, alongside mission-control and test-discipline.
• skills/mission-control/README.md updates its install step and code-lot paragraph to name code-craft alongside test-discipline as a mandatory companion skill.

Removed

• The completed docs/plans/ and docs/specs/ design-fidelity planning documents, superseded by the shipped skill.

Fixed

• The README hero pointed at flight-deck-x-banner.png, a gitignored social-media asset, so it resolved to a 404 on GitHub; a resized copy now ships at .github/assets/banner.jpg.
• The README's opening paragraph counted two skills where the package ships four, undercounting by two once code-craft and design-fidelity are included.
• tools/doctor.sh's required skill-folder check omitted code-craft, so an install missing only that folder still passed clean; the enumeration comment and loop now include it.
• The installer prompt's step 6 hook registration JSON hardcoded $HOME/.claude, ignoring the CLAUDE_CONFIG_DIR override from step 1; README and hooks/HOOKS.md now reference the resolved config directory.
