SDLC Marketplace for Claude Code

Multi-stack AI-assisted SDLC pipelines built on the Stack Provider Pattern: a single core orchestrator runs the pipeline, framework plugins register themselves via declarative stack.md profiles. No core overrides, no slot registries, no copy-paste between stacks.

v2.0.0 — 27 marketplace entries: 24 local (1 core + 5 shared libs + 7 JS/TS stacks + 4 PHP/Laravel/Symfony stacks + 3 Java/.NET stacks + 4 Python stacks) plus 3 optional external.

What is new in 2.0.0, and why each one is a breaking change:

• Measured telemetry — per-phase cost and tokens are now read from each subagent's own transcript by hooks, not estimated at chars / 4. _telemetry.json changes shape, and docs/cost-baseline.md becomes populatable for the first time.
• Resuming a run — the run marker becomes a state file, and /sdlc:start --resume continues a crashed or compacted run at the phase it reached instead of paying for it twice.
• Parallel phases — QA and security run as one step. Phase N/total now counts pipeline steps, so both members share an N, and workflow recipes gain a parallel construct.
• Security is report-only — security-analyst has no Edit tool. Critical and High findings are applied by the development architect in a fix pass, then re-verified by QA.
• Run-scoped guards — three hooks that deny staged secrets, --no-verify, and mid-run edits to tooling config, all inert outside a pipeline run.
• Agent frontmatter — skills:, maxTurns: and memory: project across every agent, and the Skill tool is now actually in their allowlists, which it never was.

Git-flow aware: the pipeline detects your branching model and your existing naming convention, classifies the task type, proposes a branch, and targets the PR at the right base — see Git Flow Awareness. Cost-optimized: model tiering + effort per-subagent, two-tier development phase (Opus plans, Sonnet implements), enforced workflow cost caps, file-scoped format hooks, shared architect conventions, per-aspect QA fan-out on full-stack runs. See MODEL-ROUTING.md for the routing audit behind the cost model, and CHANGELOG.md for the full upgrade notes.
