Claude Power Pack

v10.1.0 - A productivity toolkit for Claude Code and Codex: explicit test/review evidence contracts, host preflight, clearer init permissions and consent, and guarded framework Makefile generation.

What It Does

• Workflow commands (/flow:auto, /flow:start, /flow:eli5, /flow:finish) - Issue-driven development with worktrees, a pre-implementation ELI5 plan/necessity approval gate that cannot be bypassed (#775), quality gates, automated PR lifecycle, and CI verification. The necessity gate also ships standalone as eli5-gate - installable without CPP via /plugin marketplace add cooneycw/eli5-gate or npx skills add cooneycw/eli5-gate; CPP vendors its canonical core (file gate improvements there)
• Wave orchestration (/flow:wave, /flow:register, /flow:sync) - dependency-ordered issue waves fanned out across worker sessions, coordinated through a durable mailbox with an armed/stale/dead watch status visible on the roster (#778, #801), and per-driver capability declarations (scope, web access) so an orchestrator can check whether a driver can do the work before assigning it, not after a worker refuses (#783)
• MCP servers extending Claude Code’s capabilities:
  • Second Opinion - Multi-model code review via external LLMs (Gemini, OpenAI, Anthropic), served by the external cooneycw/mcp-second-opinion repo and registered at user scope by /cpp:init (streamable-http)
  • Browser automation - upstream @playwright/mcp server (npx/stdio, no container), registered by /cpp:init
  • Tavily - web search, content extraction, site crawling, and URL mapping via the upstream tavily-mcp server (npx/stdio), registered by /cpp:init; API key stored in AWS Secrets Manager (claude-power-pack/mcp-keys)
• PowerPoint generation - Slide decks via the native Anthropic pptx skill (npx skills add anthropics/skills@pptx)
• Security scanning (/security:scan) - Native vulnerability detection with git history analysis
• Secrets management (/secrets:*) - Tiered credential storage (dotenv, env-file, AWS Secrets Manager) with audit logging and a web UI
• CI/CD integration (/cicd:*) - Framework detection, Makefile generation, health checks, and IaC scaffolding
• Woodpecker CI - Self-hosted pipeline (secret-scan, lint, test, typecheck) with programmatic status polling
• Project scaffolding (/project:init) - Zero-to-GitHub-repo setup with Makefile, CI pipeline, and Docker config
• Skills ecosystem - Discover, install, and manage agent skills from skills.sh via native npx skills and the /plugin marketplace (the CPP /skills:* wrapper was retired in issue #437)
• CPP does not mask tool output. scripts/hook-mask-output.sh still ships and still works - it is a filter you can run over a file at rest, and /security:* uses it that way - but nothing routes live Bash or Read output through it, and CPP no longer declares anything that claims otherwise (issue #1206). Do not read unmasked output as evidence that nothing needed masking: assume everything a command prints reaches the transcript verbatim. Destructive commands are handled by Claude Code’s native git auto-blocking + OS sandbox.

Requirements

• Python 3.11+
• uv package manager
• Docker (optional - only to run the external second-opinion server locally, or as the gitleaks fallback for make secret-scan)
• Claude Code CLI
• GitHub CLI (gh) for issue/PR workflows

Install

CPP’s own plugin marketplace was retired by issue #662 and ADR 0005. Clone the repository; the tiered /cpp:init + /cpp:update symlink surface is the canonical command installation path (restored by issue #663):

git clone https://github.com/cooneycw/claude-power-pack.git
cd claude-power-pack

# The canonical installer (restored by issue #663):
/cpp:init

Existing CPP marketplace users should run /plugin uninstall @cpp for each of the 15 installed families. scripts/install-drift.sh keeps the host checks visible: it guards installed ~/.claude/scripts/ helpers against the checkout through #663’s symlink restoration, names lingering marketplace cache families as retired, non-failing migration state, and compares the installed ~/.codex/skills/ (#823) and ~/.claude/skills/ (#1029) COPIES - which git pull cannot refresh - against their sources. Every verdict is prefixed by scripts/toolchain-provenance.sh, because all of those compare against the checkout and none of them can say how current the checkout itself is (#1029). The symlink tier restored by #663 replaces those caches and follows git pull without a separate update stamp.

Host setup

/cpp:init also configures the out-of-band infrastructure used by some command families:

• External Second Opinion server - the multi-model review server lives in its own repo (cooneycw/mcp-second-opinion). Start the external server, then register it with claude mcp add --transport http --scope user second-opinion "${SECOND_OPINION_URL:-http://127.0.0.1:8080}/mcp" (for a remote host, export SECOND_OPINION_URL first rather than editing the URL, so every install names the same endpoint).
• Browser automation - registers the upstream @playwright/mcp npx/stdio server (no container).
• Tavily web tools - registers the upstream tavily-mcp npx/stdio server for web search, extract, crawl, and map. Requires TAVILY_API_KEY (stored in AWS Secrets Manager claude-power-pack/mcp-keys).
• Secrets provisioning - AWS Secrets Manager access for Woodpecker CI keys (essent-ai) and the CPP_MEMORIES_DSN common-memory DSN; fetched directly via the AWS SDK/CLI.
• Bootstrap prerequisites - jq, and the optional spec-kit CLI (specify, the engine behind /spec:adopt).
• Permission census hook + flow allowlist - registers the observe-only PermissionRequest census hook and merges the read-only /flow:* allowlist - including the audited flow helper-script rules that make /flow:auto Phase 1 prompt-free (issue #581) - into ~/.claude/settings.json (both user-confirmed).

/cpp:update refreshes those same host artifacts. See docs/HOST_MANAGED_ARTIFACTS.md for the full inventory.

Developing CPP itself

To work on CPP (not just use it), clone and run the quality gates:

git clone https://github.com/cooneycw/claude-power-pack.git
cd claude-power-pack
uv sync --extra dev
make verify

make verify closes by naming every checker in the repository it did NOT run, with the reason for each - host-dependent checks, network checks, and the control battery. A checker accounted for nowhere fails the gate, so one cannot be added and wired to nothing (#1028).

.claude/commands//*.md is the permanent source of truth. It feeds only the generated Codex harness surface: scripts/codex-skill-sync.py emits per-command Codex skills under codex/skills/ (make codex-skills, issue #555), guarded by an explicit codex-skills-check step in both CI and make verify (#1028). A bundled helper ships with what it actually runs - its sibling scripts and the libraries it imports - so the shipped copy can start. The older flat codex/prompts/ surface it replaced was retired at the #556 cutover. Codex’s GLOBAL instructions are a separate, opt-in surface: make codex-global-agents builds ~/.codex/AGENTS.md from ~/.claude/CLAUDE.md plus the owner’s ~/.codex/AGENTS.local.md, and /cpp:status reports when the two have drifted (#1441).

Key Commands

MCP Servers

CPP ships no container runtime (retired in #469). The /second-opinion:* and /evaluate:* commands consume an external second-opinion server that runs from its own repo:

• Server repo: https://github.com/cooneycw/mcp-second-opinion (server + the AWS Secrets Manager Agent sidecar build recipe + a standalone docker-compose)
• second-opinion is registered at USER scope as a streamable-http client at ${SECOND_OPINION_URL:-http://127.0.0.1:8080}/mcp (issues #633, #1256): localhost 8080 by default; for another host export SECOND_OPINION_URL with the base url, no /mcp (e.g. export SECOND_OPINION_URL=http://127.0.0.1:8090, or a Tailscale URL), before registering. CPP ships no project-scope .mcp.json entry, so nothing competes with the user-scope one. Start the external server, then register it (/cpp:init and /cpp:update do this for you):

claude mcp add --transport http --scope user second-opinion "${SECOND_OPINION_URL:-http://127.0.0.1:8080}/mcp"

Browser automation uses the upstream @playwright/mcp npx/stdio server (registered by /cpp:init). Tavily web search/extract/crawl/map uses the upstream tavily-mcp npx/stdio server (registered by /cpp:init); its API key (TAVILY_API_KEY) is stored in claude-power-pack/mcp-keys alongside the Second Opinion keys. CPP stores no application secrets on disk and runs no secrets sidecar; the remaining AWS Secrets Manager consumers (essent-ai for Woodpecker CI keys and the CPP_MEMORIES_DSN common-memory DSN) fetch directly via the AWS SDK/CLI.

CI/CD

Woodpecker CI runs on every push and PR via a self-hosted agent:

• Secret scan: gitleaks over the tree before anything else runs
• Tool staging: shellcheck-stage and jq-stage copy their content-pinned binaries into .ci-bin for the steps that need them. Staging is deliberately SEPARATE from the gates that use those tools (#1086): validate needed one second of copying from a step that also spent thirty seconds linting, and pytest sat behind all of it
• Validate: lint (ruff) + test (pytest, parallel with an explicit worker cap - never -n auto) + typecheck (mypy) in a single consolidated step
• Negative controls: every registered gate must still report BAD on its known-bad fixture and GOOD on its known-good one, and each control must be demonstrated against a vendored anchor that MISSES the known-bad input - a control with no anchor is UNPROVEN and fails the step (#924). A case may also register that the gate must REFUSE a verdict - the “I could not look, or could not look completely” branch every gate here has - which is told apart from both a finding and a crash by a declared marker (#1129)
• Python SAST: bandit over lib/ and scripts/, gated at severity >= MEDIUM (#962). The skip list is EMPTY: codex-power-pack’s inherited --skip B104,B108,B310,B602 was measured against this tree and found to remove 10 of its 11 MEDIUM+ findings, because shell=True and hard-coded /tmp paths are what a repository of shell-out helpers does. The accepted residual lives one line per (file, rule, count) in .bandit-audit-allow, so a new site is a finding and a fixed one turns the gate red until its line comes out - though a same-count replacement is a named, tested blind spot rather than a claim. The step runs the live positive control BEFORE the audit, because a scan that cannot see prints the same clean line as a clean tree. The band BELOW that threshold is enumerated by RULE CLASS rather than counted in aggregate (#1114): all seven classes in this tree were read and accepted, each carries a reviewed-low record pointing at ADR 0010, and a LOW finding whose class has no record reddens the gate - which is the opposite of the --skip #962 rejected, since it suppresses nothing and adds a distinction the count could not draw
• CI verification: flow:auto polls the Woodpecker API after merge to confirm the pipeline passes

The image-build, CVE-scan, SBOM, compose-policy, and runtime-smoke stages were retired with CPP’s Docker MCP runtime in #469.

Architecture: Woodpecker server on a dedicated VM, agent on the dev workstation, connected via gRPC over Tailscale. Web UI at woodpecker.essent-ai.com via Cloudflare tunnel.

Changelog

What a version number means here (Nit Store #864, absorbed into #1499): each heading below is a MILESTONE recorded against rolling main, not a git tag or a GitHub release - the only tag this repository has ever cut is v1.1.0, and no release has been published. Cutting an actual tagged release is a separate, standing operator checkpoint tracked at #1278; until that happens, “v10.1.0” names a point in this Changelog and in pyproject.toml, not a commit you can fetch by tag.

v10.1.0 (2026-10-28)

Minor by explicit owner ruling: “CPP didn’t augment anything new. if anything, v10.1”. This supersedes #1278’s consumer-action-to-MAJOR rule for this release. It records 35 commits since 10.0.0, including clearer setup choices, shared host preflight, reviewed-artifact evidence and guarded Makefile generation.

Behaviour changes you may notice. Quiet successful tests now warn unless silent_success is declared per command. New schema 5 receipts need a committed checkpoint and exact reviewer runtime evidence; historical receipts stay valid. CPP’s runner requires installed Python 3.11 with no implicit download. Standard GitHub permissions are list/view only in its read categories; Trusted prompts on every push and gh api, and YOLO is explicit opt-in. Init discloses writes and credential storage before consent and no longer probes writability beforehand. detect --generate-makefile refuses existing entries unless explicitly forced. Two new init gates and the writer control check the supplied promises/calls. The full consumer-action ledger also covers helper paths, guarded merges, CI identity/status, wave/session contracts and bounded evaluation/resume evidence.

This is a version milestone on rolling main: no tag or GitHub release. The broader init redesign, framework-first ordering and general rechecker remain #1587 work. Advisory evaluation remains bounded and current content is stale; this release makes no claim of behavioral assurance or deployed-host upgrades.

v10.0.0 (2026-10-21)

A major bump, for one change that requires action from anyone building on CPP. It is in the CHANGELOG’s Breaking block with the action:

• gh-pr-merge.sh, and so /flow:merge, no longer retries a protection-blocked merge with --admin just because the actor is an admin. Pass --allow-admin-retry or --admin to ask for it (#1489).

What else changed. Almost all of 10.0 is the 2026-10-20 Nit Store sweep (#1483-#1499): 34 commits, 25 of them fixes, mostly to tools that reported a non-answer as an answer. The finish gate stops counting a nested pytest summary, or a deliberate negative control, as a real failure (#1485, #1503). flow-ci-status stops blaming a cancelled step on the change, and reports it as canceled (#1486). /flow:check stops calling a run with zero checks ready (#1493). /project:next stops dropping dependencies after the first word of a Depends on: line (#1488). worktree-remove.sh refuses before it can half-delete a worktree, and for one already left that way it verifies ownership through --owner-repo and prints the cleanup commands instead of running them (#1491, #1520, #1524). /flow:auto refuses to start on a charting issue, or on an issue whose labels it could not read (#1490). /flow:deploy now checks the served release, without turning a repository that never configured a release probe into REVIEW (#1497). The Python template from /project:init builds again (#1477, #1478).

What this release is not, and what is still owed:

• Not a tag or a GitHub release. Like 9.0, this is a version bump on main. Cutting a tag is a separate operator decision (#1278).
• Not a complete contract update for canceled. The script emits it, but /flow:auto’s Step 8 contract block and docs/scripts.md still list four values. That is recorded in the Nit Store (#864), not fixed here.
• Not a change to /flow:merge’s own call site. It still passes no admin flag. That is the point of #1489: an admin override is the caller’s decision.
• Not the paused evaluation programme: #1084, #1367 and #1371, and draft PR #1393, are unchanged since 9.0.

v9.0.0 (2026-10-17)

A major bump, because six changes require action from anyone building on CPP. They are listed, each with the action, in the CHANGELOG’s Breaking block:

• .claude/hooks.json is deleted, and CPP no longer claims to mask tool output (#1206).
• /flow:auto_codex is retired; use /codex:auto (#1017).
• /flow:auto commits plan records (docs/flow-runs/issue-.md, .as-read.md) into your branch (#1080, #1081, #1082, #1320).
• Every CPP pull request must commit a counter-model receipt, enforced in CI (#1452).
• counter-model-receipt.py write --status ran requires --scope (#1461).
• A receipt write with both CLAUDE_CODE_SESSION_ID and CODEX_THREAD_ID set must name the implementer (#1453).

What the counter-model review now records, and how it is measured. The reviewer’s network fence is measured rather than promised (CODEX_REVIEW_NETWORK, #1450, #1458). The credentials an ordinary gh, git or ssh call would discover are withdrawn from it, and a credential in the repository’s own config is measured (local_credentials, #1459). A read denied mid-review stops a receipt claiming full scope (#1461). A Codex, Qwen Code or OpenCode implementer is derived from its own session record (#1453, #1454).

What this release is not, and what is still owed:

• Not a live-model test of the Qwen Code and OpenCode lanes. Their receipt derivation is pinned to real harness output captured against a stub endpoint (#1454). A live-endpoint capture to diff against is owed (Nit Store #864).
• Not a check of backtick path:line citations. They stay unchecked by ruling (#1460): of 40 measured, none was rot. Only relative markdown links are gated, now in CI.
• Not a backfill of past receipts. Ten reviewed changes carry none: the reviews for issues #1162, #1165 and #1166, and seven PRs listed on #1452. They are recorded as known gaps, not reconstructed.
• Not a security boundary. The reviewer’s withdrawal covers what an ordinary call discovers. A file readable by absolute path, or ~/.ssh for a direct ssh, is not withdrawn. Containers are not a trust boundary.
• Not a provider-diversity rule. “Cross-model” still means a different model id, so Codex gpt-X reviewing Codex gpt-Y passes. Whether it should mean a different provider is an open question (Nit Store #864).
• Not the paused evaluation programme: #1084, #1367 and #1371, and draft PR #1393 behind skillc #288 (itself blocked by skillc #334, also open), are still open.
• Changelog entries for 186 of these PRs are one line each, derived from commit titles. They are not hand-written prose. 13 test-only fixes are omitted.

v8.0.0 (2026-09-15)

A major bump because it changes how work is ACCEPTED, not what commands exist. An instrument without a negative control stops being shippable, and cross-model review moves from an opt-in command to a default stage. Both change the contract with anyone building on CPP.

Three ADRs, and 0008 and 0009 are siblings.

• ADR 0008 - before you ship an instrument, name the input that makes it report the other verdict. An instrument that cannot fail is not evidence: a green from a blind one and a green from a working one look identical. Bounded so it is affordable - the rule is owed where a verdict is consumed by a decision that will not independently re-derive it.
• ADR 0009 - before you ship a two-sided change, name the observation that would move the setting back, and commit it beside the setting. Same epistemics, different object: 0008 governs instruments, 0009 governs the knobs those instruments are set with. If you cannot name one, it is not a decision - it is a preference, and it will oscillate.
• ADR 0007 - a second model reads the branch before the PR exists, by default, stated as a property rather than a tool name: the reviewing model must not be the implementing model.

Registered negative controls went from nothing to six. At the end of 2026-09-14 the controls/ directory did not exist. The machinery itself landed the next morning (#924), and by the end of 2026-09-15 six controls were registered - check-negative-controls, check-negative-fixture-preconditions, check-oscillation, check-test-binary-guards, secret-scan, shellcheck-gate. The framework is registered in its own framework, which is the point: a control battery nothing checks is the defect it exists to find.

The rest of this section is a dated snapshot of 2026-09-15, and two of its statements were closed by #1036 on 2026-09-20. The snapshot is kept rather than rewritten, because what it records is a repository that could see its own accounting defect and say so before it had a fix - and a passage edited to look correct would destroy exactly that. What changed:

• check-oscillation was added to the census by 967c098 (#1060), so the live non-member named below no longer exists.
• the summary line no longer has the defect it is criticised for here. It now states the RELATION rather than two counts pressed together - 22 registered, 22 of 90 enumerated instruments ... carry a control that discriminates, none registered outside the census; the denominator is 76 registrable + 14 external subject(s) with no file under scripts/ for a marker, reachable only by wrapping; discovery reads scripts/* (top-level files only ...). A registered control whose gate is absent from the census is NAMED, derived on every run. Reporting it is not yet FAILING on it; that is a separate decision and printing the fact does not pre-empt it.
• Every count below is a 2026-09-15 figure, not a current one (#1272). The registered-control count and the census size have both grown since and keep growing, so no replacement number is written here - it would be the next stale one. Derive them instead: make negative-controls prints NEGATIVE_CONTROL_REGISTERED: and the enumerated relation, and make instrument-census-check reads the census rows of ADR 0008. The CI step list likewise changed: the hadolint Dockerfile lint named in the external-binary list below was retired by #943.

Deliberately not stated as a coverage fraction over the 63-row census, because the two numbers are counted independently. Five of the six register against a row in ADR 0008’s census; check-oscillation is a new instrument that the census does not yet enumerate, so the registration count is not a subset of the census and “6 of 63” would be a fraction whose numerator and denominator do not describe the same set. secret-scan also covers only the working-tree half of its row - the CI step scans git history as well - and its manifest says so. The gate’s own summary line does print N of 63; that line had the same defect and was recorded rather than quietly worked around - then fixed under #1036, which is what the note above describes.

Two counts, both honest, and neither is the other: six registered controls, and 63 enumerated instruments. Of the 63, discovery can currently find a registration marker only in a top-level scripts/ file, which is 48 of them - the other 15 are external binaries and module entry points (make verify, ruff, mypy, pytest, gitleaks, hadolint, lib.cicd x7, lib.security x2). That is a limit of where the scan looks, not a hard ceiling: secret-scan registers a control for gitleaks precisely by wrapping it in scripts/secret-scan-check.sh, so a wrapper is the available route for the other fourteen.

The six is the gate’s own output (NEGATIVE_CONTROL_REGISTERED: 6), not a file count. A recursive search under controls/ returns eight - the two extras are toy fixtures inside check-negative-controls’ own test cases - and a repository-wide search returns nine, the ninth being an unrelated prototype manifest under docs/research/. Neither file count is the figure, and both look like an inflated headline.

Counting the six needs nothing; seeing all six PASS needs the CI dependencies. Registration is a discovery count and reports 6 regardless of whether each control can run. The verdicts are what depend on tooling: controls/secret-scan needs gitleaks, which CI stages into the negative-controls step and a typical developer host does not have, and there it refuses rather than passing. It is the inverse of the usual trap - load-bearing where it gates, unrunnable where it was written - so a clone that sees the refusal is missing a tool, not reading a wrong figure.

That refusal was UNSIGNALLED when this was written, which said “the gate exited like a finding and said nothing that identifies one” - an accusation about our code for a fact about the machine. Since #1117 it is UNAVAILABLE, and make verify consumes the battery locally with --allow-unavailable, which names every unexamined control instead of either failing on it or counting it as covered. CI still passes bare --strict, where a missing tool means a staging step stopped delivering and is still a red.

What the counter-model stage measured on its first run. 16 red cases proposed, 3 already covered by the implementer’s tests - 13 novel. Taken on an adversarial workload: the change was authored by a session that had spent that day on this exact defect class, with ADR 0008 merged the previous afternoon (2026-09-14) and ADR 0009 that same afternoon (2026-09-15), the latter by the same author. If the two models were agreeing by shared training corpus rather than reviewing, that is the run where it would have shown. Stated with the number, because a favourable measurement whose conditions are not recorded gets discounted later by a reader assuming they were easy.

A measurement corrected in flight, recorded rather than quietly replaced. The harness-strategy research below reports 0 of the last 200 merged PRs ran cross-model review, against a positive control of 199/200. Re-derived on 2026-09-15 that is superseded: 21 of 200, positive control 197, and the shape is the finding - 0 of 170 across two months, then 21 of 30 in two days, because a wave orchestrator declared the driver in policy. The number moved because of an intervention by the party doing the measuring, so the thesis is not “an opt-in stage does not exist” but “it exists exactly as long as someone with authority keeps re-imposing it, and that mandate dies with the wave” - which is why 8.0 makes the stage a default rather than a command. The research document is left as written; it was true when written.

Those are MARKER counts, not execution counts, and the distinction is one of 8.0’s own findings. They count PR bodies containing a heading the run was instructed to write - so a review that happened under a different heading is counted as not having happened. PR #1000 is exactly that case, inside the measured window: two review passes, eleven findings fixed, no marker. The positive control shows the query works; it cannot detect this class of false negative. ADR 0007 replaces the marker with a receipt written by the run, which fixes it going forward; the historical count is not recoverable.

The reasoning, not marketing. Why an instrument now needs a red case is a question with an evidence-based answer, and these are the documents that carry it:

• docs/research/spec-driven-development-2026.html - the conference-grounded review (AI Dev / AI Native DevCon, AI Engineer World’s Fair 2026, AIware 2026, GitHub Universe / Microsoft Build) that established the position 8.0 implements: the 2026 consensus is spec-anchored, not spec-as-source; the centre of gravity moved from “spec” to “harness”; and verification outranks generation.
• docs/research/harness-strategy-recommendation-2026-09-14.html - the strategy: keep CPP rather than migrate to a skills framework, bound the negative-control discipline so it is affordable, and make the counter-model routine.
• docs/research/issue-quality-assessment-2026-09-14.html - the delivery-quality review that set the constraint on how 8.0 was scoped: “adopt the proportional issue contracts already delivered rather than building another governance layer.”

v7.5.0 (2026-09-07)

• Wave reliability fixes - /flow:wave mailbox watch state is now fused from the live watcher count and its heartbeat stamp so a dead watch can no longer be reported as armed (#801); a post-clearance PR pipeline watch (flow-pr-watch.sh) classifies a cleared PR’s next CI run as green/cancelled/flake/red/timeout instead of leaving it unwatched (#788); delegated driver lanes (/codex:auto, /qwen:auto, /gemma:auto) now judge run success from the payload rather than a misleading $?, after the Qwen CLI was found reporting is_error: false on a dead endpoint (#798); seven other confidently-wrong flow-wave-mailbox watch reports fixed (#792)
• Driver capability declarations (#783) - scripts/flow-driver-capability.sh declares each delegated driver’s scope (general vs. implementation-only) and web access so an orchestrator can check fit before assignment instead of after a worker refuses
• Wave roster shows who’s actually listening (#778) - flow-wave-mailbox.sh watch stamps a heartbeat so the roster can tell an armed watch apart from one that died silently
• No-bypass gates extended to the delegated drivers (#784, #775) - the ELI5 plan/necessity approval gate and its delegated-driver equivalent now have no invoker-typed or trailer-based bypass on any of the four drivers

v7.4.0 (2026-07-18)

• Top-level commands folded into families + discovery-completeness gate (#582) - /project-next / /project-lite became /project:next / /project:lite; /dockers, /happy-check, /load-best-practices, /load-mcp-docs moved into the cpp family; a new gate fails CI on any command left outside .claude/commands//*.md, since that path is what both the plugin and Codex-skill generators discover from

v7.3.0 (2026-07-04)

• Plugin-marketplace distribution + install-path cutover (epic #417 Phase B, ADR 0001) - CPP adopted 15 per-family plugins and retired its earlier symlink surface (#477/#478/#479/#480). Reversed 2026-08-11: issue #662 / ADR 0005 retires CPP’s marketplace lane after version-stamp drift proved unreconcilable; uninstall existing families with /plugin uninstall @cpp. The tiered /cpp:init + /cpp:update symlink surface returned as canonical in #663.
• Docker MCP runtime retired (#469, #423) - Second Opinion moved to its own external repo (cooneycw/mcp-second-opinion) consumed via a streamable-http client registration; browser automation moved to the upstream @playwright/mcp npx server. CPP ships no containers and make deploy is an informative no-op.
• /flow:eli5 necessity gate extracted to the standalone eli5-gate plugin (#443); CPP vendors its canonical core with a drift check.

v7.2.0 (2026-06-28)

• /flow:eli5 + /flow:auto approval gate (#398) - plain-language intent, necessity/staleness verdict, and a plan-approval pause between Analyze and Implement
• Skill drift/orphan detection in /cpp:update (#395) - curated-list-driven detection and guarded prune of retired/orphaned generated skills
• Fix: drift-detect.sh no longer reports false Docker/systemd “deployment model conflict” on Docker-only hosts - systemd unit presence now derives from LoadState, not is-active (#400)

v7.1.0 (2026-06-07)

• Skills ecosystem integration - New /skills:* command family wrapping the npx skills CLI for discovering, installing, and managing agent skills from skills.sh
• Quality vetting in /skills:find checks install counts, source reputation, and GitHub stars before recommending

v6.0.0 (2026-05-31)

• Breaking change: Docker-only MCP deployment - Docker with local builds is now the only supported Tier 3 runtime
• Legacy systemd migration - cpp:update detects legacy MCP systemd units and guides teardown before Docker refresh
• Status clarity - cpp:status reports Docker (local build) and labels remaining systemd units as migration-required legacy state

v5.2.0 (2026-03-08)

• C4 diagram QA framework - validate_diagram MCP tool with density scoring, XSS sanitization, WCAG AA contrast checks
• Multi-diagram C4 generation - L3 for all containers, L4 for top 3 components per container
• Density-aware splitting - split_diagram MCP tool auto-splits large diagrams into summary + detail views
• QA gating in skills - c4 and pptx skills check warnings after every generate_diagram, retry on edge errors, split on overflow
• Shared theme tokens - ThemeTokens contract for consistent colors across all diagram types
• c4-manifest.json - Tracks all generated diagrams with parent-child relationships
• index.html - Hierarchical navigation page for all C4 diagrams
• XSS fix - HTML-escape all node labels in diagram output
• WCAG AA fix - All color palettes meet 4.5:1 minimum contrast ratio
• 496 tests - Comprehensive test coverage for validation, density, splitting, contrast, and C4 integration

v5.1.0 (2026-03-07)

• Woodpecker CI pipeline - Self-hosted CI with MCP image security gates
• Runtime smoke tests - CI brings the MCP stack up in an isolated compose project, checks service health, then tears it down
• CI verification in flow:auto - New Step 7/8 polls Woodpecker or GitHub Actions after merge, blocks deploy on failure
• Consolidated pipeline - Merged lint/test/typecheck into single validate step (eliminates 2x uv sync)
• Health-based runtime checks - docker compose --wait validates container healthchecks during smoke runs
• Extended CI polling - flow:auto timeout increased from 5 to 10 minutes
• Woodpecker v3 API fix - Repo ID lookup for correct API path

v5.0.2 (2026-02-27)

• Nano Banana: Base64 OOM guard, Docker path fallback, validation tightening
• SlideDefinition dataclass for PowerPoint generation
• MCP server drift detection in /cpp:update

v5.0.1 (2026-02-26)

• PPTX QC validation, multi-framework support, AWS gating
• Em dash cleanup across all markdown and documentation
