Why: two blind verifiers re-ran the five preceding commits and found four defects of the same class this branch exists to close -- a confidently stated measured claim that does not survive re-measurement -- this time inside the fixes themselves. - AGENTS.md:41 still carried both phrasingsc68e864reports having corrected. `grep -rn repo-defined` returned exactly one hit repo-wide: that line, in the file every session preloads.4d336bbedited the line directly above it. - ADR-0021 asserted twice, in the section justifying that no gate is added, that the ADR-0020 validators "never open an apm.yml". All three open and yaml.safe_load it (skill-size-check.sh:342, both validate.sh). The conclusion survives -- none reads the description: key, and their globs are SKILL.md and *.agent.md only -- but the stated mechanism is falsified by one grep. - architecture.md said the ADR directory holds 20 numbered ADRs;c7ba3d2made it 21, andc68e864audited that file for exactly this class of stale count. The number is dropped rather than corrected: `ls docs/adr/` is already the index, so a count in prose is a second thing to maintain. - gates.md's new three-verdict table said `-> name` promotes an unresolved target to ERROR. Reproduced with fixtures: NAME_HYPH (skill-size-check.sh:543) requires a hyphen, so `-> gitea-prs` is checked and `-> triage` is not extracted at all, and the unicode arrow is never recognised. The SUGGESTION text advises that spelling, so taking its advice can silence the finding. The gap is now documented as a defect; nothing covers it, since the one arrow case in test-adr0020-targets.sh happens to use a hyphenated target. Implementation notes: - AGENTS.md:48's coverage claim is shrunk rather than chased. Restoring six glossary entries did not make it true: 12 more sampled terms are undefined, three of them (trigger/capability/boundary clause) used inside CONTEXT.md itself. It now says CONTEXT.md is the glossary and is not exhaustive. - CONTEXT.md's output profile and near-miss entries are corrected against their sources. The first stated a false exclusion -- .github/plugin/plugin.json IS apm-generated; only the marketplace mirror has no profile. The second inverted its source's referent: description-quality.md defines a near-miss as a query, not a sibling skill. - The strict-mode message named jq, which no suite guards on (`command -v jq` appears nowhere in tests/), while omitting python3/PyYAML, which three do. - README's git and gitea bullets now name git-workflow and gitea-workflow. ADR-0021 leaves README the only inventory and architecture.md now points at it, so the two bullets that were short had to be completed. - ADR-0018's 2026-08-14 correction is marked superseded in place. It asserted machine state in the present tense that its own 2026-08-17 note retracts. - ADR-0021's remaining errors: six files -> four (measured fromde84d1b), the wiki description's length 114 -> 96 chars, the codex self-contradiction, the cost argument overstating bumps already owed for any skill addition, and two claims about files this branch went on to edit. - The "15 of 17 suites" figure is restored where I had removed it: it is a dated record of one incident, not a live count, and four sites now describe it the same way. Impact: 16/16 pre-push hooks pass, suite 24 passed 0 skipped 0 failed. No behaviour change; every edit is prose or a comment.

Architecture
Layered model
this repo (global defaults)
└── scripts/install.sh → ~/.claude/ (Claude Code config + content)
project repo (local overrides)
└── .claude/settings.json, CLAUDE.md (overrides global)
Content deployment model
scripts/install.sh is a deployer, not a composer. It sources scripts/deploy-manifest.sh and deploys three categories:
- Files (
DEPLOY_FILES):providers/claude-code/CLAUDE.md→~/.claude/CLAUDE.md;providers/claude-code/settings.json→~/.claude/settings.json;core/AGENTS.md→~/.agents/AGENTS.md - Executables (
DEPLOY_EXECUTABLES):providers/claude-code/statusline-command.sh→~/.claude/statusline-command.sh(with+x) - Directories (
DEPLOY_DIRS):core/→~/.claude/core/(destination fully replaced on each deploy)
Skills are not deployed by install.sh. They are distributed as plugins and installed separately — in this repo by apm install against the dependencies.apm entries in the root apm.yml, which lands them in .claude/skills/ and .claude/agents/ (ADR-0018); elsewhere by claude plugin install <name>@holocron.
~/.claude/CLAUDE.md is a thin adapter, not a content source. It imports ~/.agents/AGENTS.md (always-on rules) and governance.md (always-on governance) and carries nothing else — the content index of on-demand instruction files sits in core/AGENTS.md, deployed to ~/.agents/AGENTS.md and imported by it. All always-on content lives in AGENTS.md files so other providers can import the same source without duplication.
Plugin model
Skills, agents, MCP servers, and hooks are distributed as self-contained plugin units under plugins/, installed independently — via apm install here, or claude plugin install <name>@holocron for a host consuming the marketplace natively (ADR-0018). Self-contained is a hard constraint, not a description: a plugin is copied to a cache on install, so nothing inside it may reference a file outside its own directory. That is why the Vale styles are duplicated across two skills rather than shared (ADR-0014), and why ADR-0020's constants are copied into three validators rather than sourced from one. Each plugin is an apm package: plugins/<name>/apm.yml plus a hand-authored plugins/<name>/.apm/{skills,agents,hooks,commands,instructions,extensions}/ tree (ADR-0015). There is no hand-maintained plugin.json — every manifest and every host-visible content directory is compiled from that source.
Which plugin a new skill belongs in follows from what each one is scoped to. The boundary that matters most in practice is core vs kyberforge: core is the home for cross-cutting, repo-agnostic utility skills that a consumer would want against their repo, while kyberforge is meta-tooling for the holocron marketplace itself. A skill that authors a target repo's AGENTS.md is core; a skill that audits a SKILL.md against this marketplace's contract is kyberforge.
The second boundary worth stating is git vs gitea, because both own things called branches and both touch pull requests: git is whatever works over the git wire protocol against a local clone, gitea is whatever goes through the forge's HTTP API. That is why git-branches and gitea-branches both exist and are not duplicates.
These are routing boundaries, not inventories — they answer "where does a new skill go", so they deliberately do not enumerate what each plugin ships today. The plugin's published description in its apm.yml states the same boundary for a consumer deciding whether to install (ADR-0021); neither carries an inventory. For what a plugin ships today, read plugins/<name>/.apm/skills/ or the plugin list in README.md.

Two compilers produce the plugin roots you see in the tree:
apm packcompiles the manifests (ADR-0015). Per plugin:.claude-plugin/plugin.jsonand.github/plugin/plugin.json, both generated fromplugins/<name>/apm.yml. Repo-wide, from the rootapm.yml'smarketplace:block:.claude-plugin/marketplace.json(apm'sclaudeoutput profile) and.agents/plugins/marketplace.json(itscodexprofile, a differently-shaped file). Those two are the only marketplace outputs apm has profiles for — the third root manifest,.github/plugin/marketplace.json(Copilot CLI's legacy path), is a byte-identical mirror of the Claude one maintained byscripts/sync-marketplace-mirror.shand gated by thecheck-marketplace-mirror-syncpre-push hook.scripts/sync-plugin-content.shcompiles the content mirror (ADR-0017). It wrapsapm pack --format pluginand copies the resulting bundle's flatagents/,skills/,commands/,instructions/,extensions/, and mergedhooks/hooks.jsonback to the plugin root. Claude Code's installer convention-scans those flat paths and has no.apm/awareness whatsoever, so the mirror exists solely to satisfy the host's discovery contract.
.apm/ is the sole hand-edited authoring source for plugin content. An edit made in the flat mirror is discarded by the next sync and is reported as drift by the check-plugin-content-sync pre-push hook. Hand-authored material that is not an .apm/ primitive — README.md, docs/, bin/, sources.md, .mcp.json, and per-plugin extras such as plugins/git/config.example.json, plugins/gitea/references/ and plugins/bin/evals/ — lives at the plugin root and is untouched by either compiler.
That immunity is positional, not by filename. Anything placed inside a mirrored directory is destroyed regardless of what it is: sync_dir runs rm -rf "$dst" before every copy, and sync_hooks_json does the same to hooks/. A hand-written README.md under plugins/<name>/hooks/ or plugins/<name>/skills/ is deleted by the next sync with no drift report, because a file with no .apm/ counterpart is simply absent from the regenerated tree. This has already cost the repo one document — plugins/kyberforge/hooks/README.md, since restored to plugins/kyberforge/docs/hooks.md. Plugin-root documentation belongs in docs/.
Governance layer
core/instructions/governance.md is the always-on governance instruction file. Unlike the on-demand instruction files in the content index, governance.md is loaded into every Claude session via @import in providers/claude-code/CLAUDE.md. This is a technical guarantee, not a behavioural instruction — @import causes Claude Code to expand and load the file at launch, before any interaction begins.
Those on-demand files are plain markdown — no frontmatter, no schema. The agent decides when to read each one from task context and the content index label alone. Frontmatter is deferred until there is evidence that agents are loading the wrong files in practice; it is a deliberate deferral, not an oversight to close.
The governance layer has two phases:
- Phase 1 (complete): instruction and documentation layer —
governance.mdloaded via@import;docs/ai-constitution.mdanddocs/wiki/HUMANS.mdas human-facing reference;CONTEXT.mdextended with governance domain language. - Phase 2 (planned): deterministic enforcement layer — pre-commit hooks, CI gates, secret scanning, licence scanning. Specified in
docs/research/governance_principles/CONTROLS.md.
AGENTS.md pattern
This repo uses two AGENTS.md files as the provider-agnostic source of always-on rules (ADR-0003):
- Repo-level
AGENTS.md— instructions for agents working inside this repo (structure, key rules). Imported by repoCLAUDE.mdvia@AGENTS.md. - Global
core/AGENTS.md— Communication and Behavior rules that apply across all projects. Deployed to~/.agents/AGENTS.md; imported by~/.claude/CLAUDE.mdvia@~/.agents/AGENTS.md.
Both CLAUDE.md files are thin adapters: they import from their respective AGENTS.md and add only Claude Code-specific syntax (@import, content index paths). They carry no original always-on content.
This repo also has a CLAUDE.md at its root — the Claude Code entry point for working in this repo. It imports AGENTS.md and nothing else; there is no @CONTEXT.md import. It is not import-only either: below the import sits a fenced <!-- rtk-instructions v2 --> … <!-- /rtk-instructions --> block carrying the RTK command-prefix convention, which is tool-specific content with no AGENTS.md source. This is distinct from providers/claude-code/CLAUDE.md, which is the global config deployed to ~/.claude/.
CONTEXT.md is therefore not always-loaded. AGENTS.md instructs agents to read it at session start, which is a behavioural instruction, not an @import guarantee — LESSONS.md's 2026-05-17 entry proposed adding the import and it was never applied. Treat that entry as open work rather than a record of a landed change.
Reference conventions
The stated convention is that files referencing other files declare those references explicitly: the referencing file carries the forward reference (the content index in core/AGENTS.md, references: in frontmatter), the referenced file carries a when: field describing when it is loaded, and divergence between the two signals staleness. It is aspirational, not a description of the repo today — no file under core/instructions/ carries frontmatter at all, when: appears in exactly one of the 39 SKILL.md sources under plugins/*/.apm/skills/, and the reference scanner script meant to derive the reverse map ("what files reference this file?") does not exist; docs/notes/skill-implementation-workflow.md still lists it as unbuilt work. Treat it as intent for instruction files, skills, and workflow documents, not as a rule the repo enforces.
Provider model
core/ is never tool-specific. providers/ is never shared. When adding a new provider, write an adapter in providers/<name>/ that translates core content into the tool's expected format and location. The core content itself does not change.
Architectural decisions
Key hard-to-reverse decisions are recorded as ADRs in docs/adr/. There is no index file — the directory holds numbered ADRs whose filenames state their decision, so ls docs/adr/ is the index. Read a superseding ADR before the one it supersedes: ADR-0015 (apm as the authoring source of truth) supersedes ADR-0001 and moots ADR-0006, ADR-0017 corrects ADR-0015's host-discovery gap, and ADR-0019 supersedes one claim in ADR-0018 (that .claude/settings.json's committed content is exactly {"hooks": {}}) while keeping the rule behind it. Entry points for the structure described on this page: ADR-0002 (two-tier CLAUDE.md), ADR-0003 (AGENTS.md as the provider-agnostic entry point), ADR-0015 and ADR-0017 (the two compilers behind the plugin roots).
