chore(nix): pin the holochain agent skill to v1.0.0-rc.1

Intent

The holochain-agent-skill flake input was never pinned to a tag, and flake.lock still held ab02c4f from 2026-04-06, which predates every tagged release upstream. Every nix develop in this repo has been materializing a five-month-old skill into .claude/skills/holochain/, .cursor/skills/holochain/ and .agents/skills/holochain/.

This pins the input to the newest upstream release, v1.0.0-rc.1 (2026-09-04).

Changes

The pin. url now names an explicit tag instead of tracking the default branch, so the skill an agent gets is a decision rather than whatever main happened to be that day.

Two upstream breaking changes absorbed.

• The repository was renamed to holochain-agent-skills (plural). GitHub redirects, but a lock file should not depend on a redirect, so the URL names the new repo. The input attribute stays singular (holochain-agent-skill) so the nix flake update holochain-agent-skill command documented in CONTRIBUTING.md and the diagrams in pai/README.md keep working unchanged.
• The skill moved from the repository root to skills/holochain/. Fetching the root used to drag book.toml, SUMMARY.md, CHANGELOG.md, CLAUDE.md, docs/ and .github/ into the installed skill directory; the src now names the subpath, so only the skill lands.

Decisions

v1.0.0-rc.1 targets Holochain 0.7 only, and dev is still on 0.6 (hdk = "^0.6.0", holochain = "=0.6.0", holonix ref=main-0.6). The release notes are explicit that 0.6 content was removed. This is a deliberate choice to land the skill ahead of the 0.7 upgrade in #130 rather than after it, and it is worth naming so a reviewer is not surprised.

Option	Rejected because
Pin v0.2.0 (latest 0.6-compatible release)	Matches dev's toolchain exactly, but leaves the repo one major version behind and needs a second bump the moment #130 lands.
Leave the input unpinned on main	The current state. A nix flake update at an arbitrary moment silently changes what every agent in this repo reads.

Two consequences worth tracking while dev is on 0.6:

• The installed skill teaches 0.7 APIs, including the Action model rewrite. documentation/TELOS.md and pai/claude/skills/nondominium-domain/SKILL.md both route general HDK questions to this skill.
• It carries an UpgradeHolochain07 workflow, which is directly useful to chore(deps): upgrade to Holochain 0.7 #130.

How to test

nix develop
ls .claude/skills/holochain/            # assets  LICENSE  references  SKILL.md
grep 'version:' .claude/skills/holochain/SKILL.md   # "1.0.0-rc.1"
ls .claude/skills/holochain/ | grep -E 'book.toml|SUMMARY.md|docs'   # no match

Verified locally: the shellHook completes, all three harness paths (.claude/, .cursor/, .agents/) receive the same four-entry tree, and no workshop files leak in. The locked rev 28b00fc is the v1.0.0-rc.1 tag HEAD.

Documentation

docs: none. Branch prefix is chore/, and the two docs that reference this input (CONTRIBUTING.md line 168, pai/README.md) stay accurate because the input attribute name is unchanged.
