* docs(#3025): MCP tool schema as a context-budget concern Adds documentation covering the largest GSD cost lever that GSD itself does not own: MCP tool schema injection. Every enabled MCP server adds its schema to every turn (often 20k+ tokens for heavyweight servers like browser/playwright, mac-tools, etc.), which can dwarf whatever `model_profile` tuning saves. Two doc surfaces (per the bundle-docs-with-code skill depth gradient): 1. get-shit-done/references/context-budget.md - New "MCP Tool Schema Cost (Harness Concern)" section. - Explains schemas-per-turn cost framing. - Names enabledMcpjsonServers / disabledMcpjsonServers and .claude/settings.json explicitly. - Pre-phase audit checklist: browser/playwright, platform-specific, cross-project/stale, duplicate/shadow. - Explicit "GSD does not manage MCP enablement — harness concern" statement so users don't hunt for a GSD setting. - Links to Anthropic Claude Code MCP docs as canonical reference. - Notes compounding interaction with model_profile (additive levers). 2. docs/USER-GUIDE.md - New task-oriented "Trim MCP servers to reduce per-turn cost" section above "Using Non-Claude Runtimes". - Same checklist condensed. - Cross-link to context-budget.md for the full reference. Tests: - tests/feat-3025-mcp-token-budget-docs.test.cjs (12 cases) parses both docs into typed semantic-flag records and asserts behavioral invariants (mentions key, includes audit, names harness, etc.) rather than substring-matching prose. Adheres to CONTRIBUTING.md no-source-grep — section can be reworded freely as long as the required semantics survive. - Markdownlint pre-flight tests (MD040 fence language, MD056 table column count) per the bundle-docs-with-code skill so CR can't ratchet on prose nitpicks across multiple review rounds. Verification: - 12/12 pass on regression test - 6857/6857 full suite (12 net new) - lint-no-source-grep clean (377 test files) Companion to #3023 (per-phase-type model map) and #3024 (dynamic routing). Together they cover the three biggest cost levers users ask about; this issue covers the one GSD does not own. Closes #3025 * docs(#3025): batch 3 CR fixes — pr id, relative link, named flag CodeRabbit on PR #3032 (3 minor — 2 inline + 1 nitpick), all in one push per the bundle-docs-with-code skill (avoid per-round nitpick ratchet): 1. Inline (Minor) — .changeset/mcp-token-budget-docs.md:3 `pr: TBD` → `pr: 3032` so changeset tooling can link the entry. 2. Inline (Minor) — docs/USER-GUIDE.md:1101 Used a hardcoded `https://github.com/.../blob/main/...` URL for the cross-link to `context-budget.md`. Rest of USER-GUIDE.md uses relative links. Switched to `../get-shit-done/references/context- budget.md#mcp-tool-schema-cost-harness-concern` so feature-branch work shows the right content and rename-resilience is preserved. 3. Nitpick — tests/feat-3025-mcp-token-budget-docs.test.cjs:234 The cross-link assertion used an inline `/context-budget/i.test(...)` while every other invariant in the file lived as a named flag in `parseMcpBudgetSection`. Per CONTRIBUTING.md no-source-grep, added `crossLinksContextBudget` to the parser and asserted on `parsed.crossLinksContextBudget` so the cross-link rule sits next to its siblings. Verification: - 12/12 pass on regression test (no count change; refactor only) - No source code changes, only docs + tests * test(#3025): strip inline markdown before phrase-match (CR nitpick) CodeRabbit caught that the `explainsHarnessNotGsd` primary regex branch couldn't match "GSD does **not** manage" in context-budget.md because the markdown bold markers (`**`) sit between contiguous words. The test passed today only via the fallback `harness (concern|setting|controlled)` branch — the primary branch was effectively dead code. Fix: strip inline markdown emphasis (`**`, `*`, `~~`) and inline- code backticks before any phrase-matching in `parseMcpBudgetSection`. All seven flag computations now run against the stripped text so markdown formatting can't silently invalidate any invariant. Underscores are intentionally NOT stripped — `model_profile` and other snake_case identifiers must survive intact for the mentionsModelProfileInteraction check to find them. Verification: 12/12 still pass; primary branches now fire on real markdown content rather than relying on fallbacks. * test(#3025): guard markdownlint tests against null section (CR nitpick) CodeRabbit caught that the MD040 and MD056 markdownlint pre-flight tests called `section.match(...)` and `section.split('\n')` directly on the value returned by `extractSection`, which returns null when no matching header is found. If the MCP section is ever removed (regression), both tests would throw `TypeError: Cannot read properties of null` instead of producing a clean assertion failure naming the actual problem. The semantic tests above are protected because parseMcpBudgetSection short-circuits to a typed-falsy record on null input. The markdownlint tests bypassed that guard since they need raw section text, not parsed flags. Added `assert.ok(section, ...)` preconditions to both so a missing section produces a meaningful failure message. No content changes; defensive programming only. Verification: 12/12 still pass.

Documentation: MCP tool schema as a context-budget concern (#3025). Adds new sections to get-shit-done/references/context-budget.md and docs/USER-GUIDE.md explaining that every enabled MCP server injects its tool schema into every turn — heavyweight servers (browser/playwright, Mac-tools, Windows-tools) can cost 20k+ tokens each, often dwarfing what model_profile tuning saves. The toggle lives in .claude/settings.json (enabledMcpjsonServers / disabledMcpjsonServers) and is a Claude Code harness concern, not a GSD concern. Includes a pre-phase audit checklist (browser, platform-specific, cross-project, duplicates) and notes the multiplier interaction with model_profile. Companion to #3023 (per-phase-type model map) and #3024 (dynamic routing); together they cover the three biggest cost levers.
