Need help deploying Mason?
Chalk Labs sets up agents like this inside real teams: connected to your tools, tested on your data, with a human in the loop where it matters.
Install
Works with Claude Code, Codex, VS Code, Cursor, Windsurf, Claude Desktop. Read the repository before you give any tool access to your data.
npx agentmarket install connector/adrianczuczka-com-mason
Asks which of your tools to add it to (Claude Code, Codex, Cursor, VS Code, Windsurf, Gemini CLI, Claude Desktop) and shows the change first. See https://agentmart.dev/cli.

Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].
get_contextAssemble task context: matching decisions with rationale, approval, owner, sources, last review, and freshness, plus related tests, file impact, and any available map entries. Map verification is rechecked against sampled source contents; stale or unknown verification requires a fresh review, and recordedVerdict preserves the historical verdict. Proposals are suggestions; legacy records are unreviewed; accepted decisions are constraints subject to freshness. No initialization or map required. Pass task and optional files. map.status and diagnostics preserve missing or invalid knowledge. Impact…
get_impactTrace historical co-change partners, related tests, and references with evidence: resolved imports, explicit paths, or uncertain name candidates. Candidates are not proven dependencies. Deterministic and read-only; no initialization or concept map required.
get_snapshotReturn the optional feature-to-file architecture map with drift and trust evidence. Map verification is rechecked against sampled source contents; stale or unknown verification requires a fresh review, and recordedVerdict preserves the historical verdict. If no map exists, returns exists:false and points to decision context. Decision capture, get_context, and get_impact still work. No initialization required.
mason_automationInspect installed automation, observed host events, pending decision records and the notification baseline, or check all retained documentation findings across sessions. status is read-only; check saves local baselines and verification reports without editing source, approving advisories or consuming pending completion notices. Returns concise results with a full report path. Works without a map.
mason_check_driftCheck how far the concept map has drifted from HEAD. Deterministic (git + filesystem, no LLM). Returns which features/flows are stale and the changed files behind them, new source files not yet mapped, ghost files (mapped but deleted), renames, and a `recommendation`: `up-to-date` (nothing to do), `incremental` (update just the stale entries via save_snapshot), or `full-rebuild` (broad source review required). Call this before trusting the map in a long session, or when maintaining an existing map.
mason_complete_initRecord assistant instruction setup locally in ignored .mason/local/project.json, with feature settings in shared .mason/config.json. Other tools work without this marker. Repeated calls preserve the original setup time and existing settings.
mason_initInspect this project now: returns documentation audit findings, committed-diff review findings, decision/map status, and a quickstart playbook. Quickstart is read-only and deterministic. Explicit mode: setup validates shared configuration and activates locally without editing shared files; mode: init explicitly prepares MCP, instructions and lifecycle hooks for review and commit. Neither runs audits or prepares repairs; use only when requested. Optional host selects codex or claude. Optional base selects the review comparison; evidence imports CI manifests with check outcomes, commit freshness…
review_decisionPrepare a decision review: returns the record and history with its latest two inspections (older ones are counted), any operative accepted revision, provenance, changes, and source, diff and commit previews since the latest valid inspection for both sets of anchors, and a reviewToken. For accepted-guidance inspection use inspectionScope operative on both prepare and inspect; pending proposals remain unassessed. Default all scope covers both revisions. After source inspection, record inspect with inspector, note and token to report no contradiction found without human acceptance. For human revi…
save_decisionCapture or revise a decision proposal as soon as the lesson is supported by evidence, without waiting for implementation or merge. Keep unimplemented remedies tentative. Include rationale, anchors, optional owner, sources, and a known actor. Compare matching get_context records and pending proposals before saving. When new evidence changes the same lesson's assumptions, scope, or recommended action, pass its existing id, including for accepted records. Preserve supported rationale and sources and replace obsolete instructions. Create a new record for a genuinely distinct lesson; skip unchanged…
save_snapshotSave a concept-to-files map as a persistent project snapshot. Maps feature names and data flows to the files that implement them. Retained for direct maintenance of legacy maps; the managed map-build workflow has been removed. Persists across conversations — future sessions can call get_snapshot to instantly find relevant files. No API key needed — you are the LLM generating the map.
save_verificationRecord verify_snapshot verdicts using each entry’s kind and reviewToken. Missing tokens request a fresh review; changed or deleted entries return conflicts without being stamped. Entries judged ok are stamped verifiedAt; failures are flagged verificationFailed with your note and surface in get_context, get_snapshot, and mason_check_drift until corrected. Verdict notes are required for failures.
verify_snapshotSpot-check the concept map's CORRECTNESS (drift checks freshness; this checks entries were right to begin with). Returns a sample of entries — always the never-verified and least-recently-verified first — with skeletons of their claimed files, for you to judge whether the files actually implement what the entry claims. Report verdicts back via save_verification with each entry’s kind and reviewToken. Tokens bind the entry and bounded source evidence; changed evidence requires a fresh review. Run periodically, or after an automated refresh wrote entries no human reviewed.
