BDR-001 — Uniform --help helper via session-start hook (option C)

  • Date: 2026-04-22
  • Status: accepted
  • Decision: every skill expose --help via shared snippet injected by session-start hook, not duplicate helper in each SKILL.md.
  • Why: 25+ skills — keep same helper synced across every file guarantees drift. Single injection point = single source of truth.
  • Alternatives rejected:
    • Option A (copy helper into each SKILL.md) — rejected: maintenance entropy.
    • Option B (external wrapper /help <skill>) — rejected: breaks "one command = one skill" experience.
  • Reference: commit 3968a29.

BDR-002 — Move tasks/ + introduce memory + audits under .claude/

  • Date: 2026-04-23
  • Status: accepted
  • Decision: migrate ./tasks/ to .claude/tasks/, create .claude/memory/ (5 registries BDR/LRN/BLK/journal/EVAL) and .claude/audits/ for AUDIT_* files. Adapt skills/agents/CLAUDE.md. Integrate CAPITALIZE step into completion skills (ship-feature, feat, bugfix, hotfix, commit-change), add /close skill for session-end ritual.
  • Why: group all meta-project state (AI config + tasks + memory + audits) under .claude/ isolate Claude governance from real code. Aligned with official Claude Code memory docs. Without integration in completion skills, registries stay empty (aspirational text).
  • Alternatives rejected:
    • Keep ./tasks/ at root — rejected: clutters repo, mixes code signal with governance signal.
    • Use .claude/agent-memory/ for everything — rejected: agent-memory/ has distinct role (already used by other tools).
    • Ritual as aspirational text only in CLAUDE.md — rejected: zero execution guarantee, registries stay empty.
    • Stop hook to ask 3 questions every turn — rejected: too noisy.

BDR-003 — Gitignore wildcard + negations pattern for .claude/

  • Date: 2026-04-23
  • Status: accepted
  • Decision: use .claude/* (wildcard match of immediate children) + negations !.claude/tasks/, !.claude/memory/, etc., not .claude/ (recursive ignore).
  • Why: when parent ignored via .claude/, git no descend (performance optimization) and negations on children ignored — documented in gitignore(5). With .claude/*, git matches each child individually, negations active.
  • Alternatives rejected:
    • .claude/ + !.claude/tasks/ (naive) — rejected: negations no effect, everything stays ignored.
    • Drop .claude/ from gitignore entirely — rejected: .claude/settings.local.json and .claude/agent-memory/ must stay ignored (per-machine).
    • Track paths via .gitattributes or external tool — rejected: over-engineering, git handles natively.
  • Reference: commit 499cd07, git check-ignore -v verified on 4 paths (2 tracked, 2 ignored).

BDR-004 — Adopt auto permission mode as default

  • Date: 2026-04-27
  • Status: accepted
  • Decision: set permissions.defaultMode to "auto" in user-scope settings.json, drop disableAutoMode: "disable". Auto mode runs classifier on every action, blocks risky operations (curl|bash, prod deploys, force push, IAM grants, mass deletes, exfiltration to external endpoints), auto-approves local edits, lockfile-declared dep installs, read-only HTTP.
  • Why: prompt fatigue under default mode big on multi-step autonomous work. Auto mode keeps safety net (classifier review) without per-tool friction. Classifier re-evaluates conversation-stated boundaries ("don't push", "wait for review") on every check, verbal constraints carry weight.
  • Alternatives rejected:
    • Keep default — too many prompts, breaks flow on long tasks.
    • acceptEdits — eliminates prompts but no classifier, blanket trust on Bash beyond filesystem helpers.
    • bypassPermissions — skips all checks, no prompt-injection guard. Only for isolated containers.
    • dontAsk — full denylist, breaks anything not pre-approved. Suited to CI, not interactive work.
  • Caveats: requires Claude Code v2.1.83+, plan ≠ Pro (Max/Team/Enterprise/API only), Sonnet 4.6 / Opus 4.6 / Opus 4.7, Anthropic API provider. On entering auto mode, blanket allow rules (Bash(*), Bash(python*), package-manager run, Agent) dropped, restored on exit.
  • Reference: commit 1421578.

BDR-005 — motion as default animation library; advisor stays read-only

  • Date: 2026-04-27
  • Status: accepted
  • Decision: when project stack supports it, framework installs motion (or motion-v for Vue 3 / Nuxt) as default animation library. Install automatic in /init-project STEP 5e (post-scaffold), opt-in in /onboard STEP 2.5 (existing projects). plugin-advisor only detects and reports status — never runs npm install itself. Detection logic in lib/animation-lib-check.sh (sourced by all three layers).
  • Why: framer-motion rebranded motion in November 2024 (single package supporting React motion/react, Svelte, vanilla JS; motion-v parallel package for Vue). Bake new name now to avoid legacy-import sprawl across new projects. Split init-vs-onboard behavior follows trust gradient: at init, user just validated entire scaffold so silent install fine; at onboard, touching existing package.json invasive without explicit consent. Plugin-advisor kept read-only to preserve "Never modify files" contract (PHASE 4 already mutates plugin state with confirmation; piling npm installs on top blurs responsibility).
  • Alternatives rejected:
    • Pin framer-motion (legacy name) — rejected: package in maintenance mode, every new project inherits old import path.
    • Auto-install during /onboard without asking — rejected: silently adds runtime dep + ~50 KB gzip to project user did not ask to modify.
    • Make plugin-advisor install missing libs — rejected: violates read-only spec, breaks separation of concerns (advisor advises; orchestrators mutate).
    • React-only scope — rejected: Vue/Svelte teams should benefit; motion-v makes Vue case clean.
  • Eligibility rules (helper output):
    • eligible|motion: React, Next.js, Remix, Astro+React, Svelte/SvelteKit
    • eligible|motion-v: Vue 3, Nuxt
    • no|-: backend, CLI, embedded, Flutter, static HTML, React Native (use react-native-reanimated), Astro without UI integration, no package.json
  • Reference: helper at lib/animation-lib-check.sh; integration in skills/init-project/SKILL.md STEP 5e, skills/onboard/SKILL.md STEP 2.5, agents/plugin-advisor.md PHASE 1/2/3, lib/design-gate.md.

BDR-006 — Caveman as 4th always-on plugin (output compression)

  • Date: 2026-05-03
  • Status: accepted
  • Decision: install JuliusBrussee/caveman in always-on tier alongside security-guidance, superpowers, rtk. "Full" install = plugin (/caveman + cavecrew agents + plugin-scoped SessionStart/UserPromptSubmit hooks) + standalone hooks (statusline + stats badge in ~/.claude/hooks/) + caveman-shrink MCP scaffold (NOT auto-registered — proxy needs upstream wrapper). install-plugins.sh STEP 5.5 calls enable_plugin "caveman" "caveman" to write into enabledPlugins. Hook paths in settings.json normalized to ~/.claude/hooks/... post-install so user home dir no leak across machines.
  • Why: caveman compresses Claude output ~75% via caveman-speak, preserves technical substance. Symmetrical with rtk (input compression hook) — rtk shrinks tool I/O, caveman shrinks model output. Both hooks pay zero passive cost in clean session, amortize across long runs. Always-on justified: plugin auto-deactivates with phrases like "stop caveman" / "normal mode", toggle would be friction without benefit.
  • Alternatives rejected:
    • Toggle plugin (start OFF) — rejected: misses by-default benefit; user need remember claude plugin enable caveman@caveman per session, negates auto-compression value.
    • --minimal install (plugin only) — rejected: loses standalone stats badge surfacing token-saving telemetry.
    • --all install (adds per-repo caveman-rules.md etc. into $PWD) — rejected: would litter THIS config repo (cwd at install time) with rule files meant for project repos. Let users opt in per-repo when wanted.
    • Auto-register caveman-shrink MCP — rejected: proxy errors with "missing upstream command" without upstream MCP to wrap, fails health checks. Print snippet instead, let user pick which upstream they want compressed (filesystem, github, …).
  • Caveats:
    • Caveman hooks/install.sh writes absolute paths ($HOME/.claude/hooks/caveman-*.js) into settings.json. settings.json symlinked into repo, absolute path commits username. STEP 5.5 runs Python post-process to rewrite to portable ~/.claude/hooks/... form (bash expands ~ before passing to node).
    • Caveman hook files materialize in hooks/ (repo dir, not ~/.claude/hooks/) because latter is symlink. Added to .gitignore to prevent accidental commit of user-scope state.
  • Reference: install-plugins.sh STEP 5.5, lib/detect-plugins.sh detect_caveman* + plugin_enabled, doctor.sh caveman block, commit 9b20b84.

BDR-007 — Skill profiles partition gstack by usage (design / dev / qa / audit / minimal)

  • Date: 2026-05-04
  • Status: accepted
  • Decision: ship lib/profile.sh + lib/profiles/*.profile to give user fine-grained, task-shaped activation of skills. Profile = plain-text file listing skill names + types (gstack, external, personal, plugin, mcp). profile set <name> enables listed skills, disables every gstack-origin skill not in profile, by moving symlinks between skills/ and skills-disabled/. profile reset re-enables all of gstack. Plugin/MCP entries advisory — script prints manual claude plugin enable / claude mcp add command but never runs it. Surface area: one CLI (bash lib/profile.sh), one slash command (/profile), four Makefile targets, section in agents/plugin-advisor.md.
  • Why: when user works on focused kind of task (design only, qa only, audit only) full gstack (~38 skills) injects irrelevant skill descriptions into every session. Existing lib/toggle-external.sh enable|disable gstack too coarse — disables whole gstack including infrastructure skills user does want (checkpoint, ship, learn). Profiles give curated middle ground: keep gstack repo installed, hide skills not relevant to this session.
  • Alternatives rejected:
    • Fork SKILL.md files to strip ~70-line gstack preamble — rejected: every gstack upgrade needs re-fork, preamble already degrades gracefully (|| true) when gstack/bin/ unavailable. Hiding skill cheaper than rewriting.
    • Per-skill toggle via claude plugin enable/disable — rejected: gstack skills not marketplace plugins, symlinks owned by skills-external/gstack/. CLI no reach them.
    • Disable via removing symlinks (rm + recreate on enable) — rejected: lossy if user has local edits, re-creation requires running gstack own setup. Move-based toggle preserves symlink intact.
    • Auto-toggle plugins (ui-ux-pro-max) and MCPs as part of set — rejected: those affect global Claude Code state, may carry API keys (magic). Keep advisory; user runs CLI command knowingly.
    • Build giant gstack-profile CLI wrapping gstack/bin/* directly — rejected: scope creep into gstack internals. Repo already has own toggle infra (lib/toggle-external.sh); profile.sh sits alongside as finer tool.
  • Caveats:
    • Profiles do NOT change gstack/bin/ infrastructure — preamble in disabled skills still references it, re-enabling restores normal behavior. No telemetry/learnings data touched.
    • cmd_set only auto-disables skills returned by gstack_skills() (those with SKILL.md under skills-external/gstack/*/). Personal skills (real dirs in skills/) never auto-disabled by set — only added back if listed in profile.
    • cmd_current returns "full" when nothing disabled, even if profile happens to be 100% covered by current state. Active-profile heuristic requires at least one gstack__* entry in skills-disabled/ so we no lie about profile being "set" when no set ever ran.
    • Personal skills use external-style move (no gstack__ prefix) so name-collision with gstack skills cannot happen during disable.
  • Reference: lib/profile.sh, lib/profiles/{design,dev,qa,audit,minimal}.profile, skills/profile/SKILL.md, agents/plugin-advisor.md (DETECT block + TOGGLING EXTERNAL TOOLS section), Makefile targets profile*, lib/toggle-external.sh header pointer.

BDR-008 — Profile system v2: extend to plugins + MCPs + CLIs (web/seo/web-full/backend)

  • Date: 2026-05-04
  • Status: accepted
  • Decision: extend profile.sh to actually toggle Claude plugins (claude plugin enable|disable <name>@<marketplace>) and MCP servers (delegated to lib/toggle-external.sh for magic MCP, advisory for others), add CLI status reporting. New profile syntax uses plugin@<marketplace> so script knows where to enable from. New profiles shipped: web (frontend website), seo (SEO/GEO/W3C audit), web-full (web + seo combined), backend (API/system dev — no design, no SEO). Reverted v1 decision (BDR-007 alternative #4 "advisory only for plugins/MCPs"): user explicitly asked for actual toggling so set web actively enables ui-ux-pro-max + magic, set seo actively disables ui-ux-pro-max. Always-on plugins (caveman, security-guidance, superpowers) protected by both allowlist (MANAGED_PLUGINS) and denylist (PROTECTED_PLUGINS).
  • Why: v1 profiles only managed skills (symlink toggle). User feedback: "active TOUT le splugins necessaire pour tel profile et desactive les autre". Pure-skill toggling left ui-ux-pro-max/magic always loaded regardless of profile, passive token cost no drop as much as expected when switching to non-design profile. Auto-toggling plugins shifts design from "show me right skills" to "set up right session" — closer to what user actually wants.
  • Alternatives rejected:
    • Keep plugins advisory + add --apply-plugins flag — rejected: user has to type flag every time, defeats "switch profile to switch context" workflow.
    • Disable ALL non-listed plugins (including third-party user-installed ones) — rejected: too aggressive. Profile system has no business touching plugins user installed for own reasons. Solution: explicit MANAGED_PLUGINS allowlist (currently 3 entries) — script touches only those.
    • Treat MCPs identically to plugins (auto-toggle any MCP) — rejected: MCPs typically need env vars / API keys / specific commands. Auto-registering with wrong config produces broken MCPs (LRN-006). Compromise: auto-toggle ONLY magic because already have its config in lib/toggle-external.sh. Other MCPs stay advisory.
    • Track plugin state across set/reset cycles, restore on reset — rejected: complexity not worth it. reset re-enables gstack skills only. To re-enable managed plugin, user runs apply <profile> or explicit claude plugin enable command. Documented in info line printed at end of reset.
  • Caveats:
    • MANAGED_PLUGINS hardcoded — adding new toggle-managed plugin requires editing profile.sh. Acceptable for now (3 entries, rarely changes); revisit if grows.
    • claude plugin enable returns success even for already-enabled plugins, parser greps for "enabled|already" in stdout/stderr. Works on current Claude CLI; brittle if CLI rewords messages. Acceptable risk.
    • current heuristic now counts installed (CLI status) as available. Without that, profiles listing CLIs would never reach 100% match. Tiebreaker: when two profiles tie on %, larger total wins (web-full > web > design when all are 100%).
    • cmd_show widened TYPE column to 30 chars to fit plugin@ui-ux-pro-max-skill without breaking alignment.
    • mcp magic toggle delegates to lib/toggle-external.sh enable magic which requires MAGIC_API_KEY in .env. If key missing, profile.sh prints info line and continues — rest of profile still applies.
  • Reference: lib/profile.sh (MANAGED_PLUGINS/PROTECTED_PLUGINS arrays, skill_status plugin@/cli/mcp branches, enable_skill/disable_skill plugin@ + mcp branches, cmd_set plugin disable loop, cmd_current available-counting), lib/profiles/{web,seo,web-full,backend}.profile, refined lib/profiles/{design,dev,qa,audit}.profile (use plugin@<marketplace> syntax + cli entries), skills/profile/SKILL.md (updated profile table + mechanism table), agents/plugin-advisor.md (extended profile recommendation table).

BDR-009 — Mandate caveman format on .claude/memory/ registries

  • Date: 2026-05-05
  • Status: accepted
  • Decision: all writes to .claude/memory/*.md (decisions, learnings, blockers, journal, evals) MUST use caveman style — drop articles (a/an/the), drop filler (just/really/basically/actually/simply), fragments OK, short synonyms (big not extensive, fix not "implement a solution for"). Keep technical terms exact, code blocks unchanged, error messages quoted exact, IDs (BDR-XXX, LRN-XXX, BLK-XXX, EVAL-XXX) and dates unchanged. Pattern: [thing] [action] [reason]. [next step]. Rule added to CLAUDE.md "Memory registries" section. Applied retroactively to existing 5 registries via /caveman:compress. Pre-compression backups saved as *.original.md (gitignored).
  • Why: registries loaded every session start (per CLAUDE.md "Session start" step 1) — every token compressed cuts permanent input cost. Measured ~40% input-token reduction across 5 files (164→97 lines on average per registry). Caveman style preserves all technical substance (code, IDs, error strings, refs) while dropping prose padding that no engineer needs at re-read. Rule mirrors English-only rule that already governs registries — both about read-efficiency, not aesthetics.
  • Alternatives rejected:
    • Compress only on new entries, leave existing prose untouched — rejected: every session-start still pays 40% prose tax on legacy entries (largest part of file). Mixed-style file harder to scan than uniform compressed file.
    • Use lighter compression (drop only fillers, keep articles) — rejected: half-measure. Caveman lite saves ~15%, full saves ~40%. Cost identical (one /caveman:compress run).
    • Move registries to JSON/YAML for max density — rejected: registries are narrative (BDR rationale, LRN context). YAML/JSON would lose nuance, force schema rigidity. Caveman keeps prose readable, just compressed.
    • Skip rule, rely on writers to compress organically — rejected: untested writers (skills, future agents) revert to verbose prose. Explicit rule + caveman-mode-active hook ensures consistency without per-skill enforcement.
  • Caveats:
    • Code blocks, error strings, commit refs, IDs, dates, file paths MUST stay byte-exact — caveman applies to prose only.
    • User-facing CAPITALIZE prompts may stay verbose / mirror user language; rule applies only to written entry.
    • *.original.md backups gitignored (BDR-009 commit 639486a) — recoverable via git history of pre-compression commit.
    • Existing registries entries compressed in commit e4a9259; new entries written caveman from start (BDR-009 itself is first such entry).
  • Reference: CLAUDE.md "Format — registries ALWAYS caveman" section, commits 520188a (rule added), e4a9259 (5 registries compressed), 639486a (gitignore backups).
