# Compiled project context > Verified, budgeted project evidence with explicit local refresh and read-only remote previews. Section: Guides Canonical: https://gno.sh/docs/compiled-context Markdown: https://gno.sh/docs/compiled-context.md Compile a verified Context Capsule into a separate, cited Markdown file for a project. The renderer preserves source passages as untrusted evidence; it does not summarize with a model, edit `AGENTS.md` or `CLAUDE.md`, or enable background refresh. Identical verified inputs and budgets produce identical bytes. ## Build and compile ``` # Refresh indexed source state before checking freshness. gno update gno context build "project launch decisions" --collection work --budget 12000 --fast --json --output capsule.json gno context compiled preview --capsule capsule.json --budget 12000 gno context compiled compile --capsule capsule.json --budget 12000 --output project.gno-context.md gno context compiled check project.gno-context.md ``` Replace `work` with your configured collection. Compile requires a new output ending in `.gno-context.md`. It also writes a private adjacent `project.gno-context.md.json` sidecar recording ownership, the Capsule path, settings, and hashes. Keep the Capsule and sidecar for local refresh. It refuses existing or unowned destinations and symlink traversal. `--budget` is a positive token limit (at most 1,000,000); optional `--bytes` limits the entire output to at most 4 MiB. Metadata, framing, citations, and passages all count. Inputs are bounded to 4 MiB. `--json` exposes actual token and byte costs, estimator identity, coverage, evidence IDs, omissions, output digest, and verification digest. A budget can omit required facets: inspect `coverage.complete` and `unresolvedFacets`, not just whether compilation worked. A budget too small for framing fails. Compilation requires Capsule 1.1/1.2 retrieval and egress provenance and current source/authority checks. Rebuild older Capsules. A recorded active tokenizer must be available with the matching identity; there is no silent estimator fallback. Private collection rules still apply when input JSON is supplied inline. Verification checks the current **index**, not unsynced source files: run `gno update` after editing sources before relying on a freshness result. Keyword facet coverage is a lexical signal, not semantic completeness or proof that every required source was found. Distinct relevant, nonoverlapping passages remain eligible even when their keyword facets are already covered, subject to the remaining budget and per-source share limits. Duplicate and overlapping evidence is still collapsed. ## Check and refresh `gno context compiled check` is read-only. It preserves the unrelated `gno context check` configuration-validation command. - current: exit 0; owned bytes and indexed evidence verify. - stale: exit 3; inspect reasons and refresh explicitly. - conflict: exit 4; preserve and inspect hand edits. - unverifiable: exit 2; repair missing companions, authority, or capabilities. Invalid command input uses exit 1. Reasons accompany non-current results; check does not return evidence text on drift or authorization failure. ``` gno update gno context compiled refresh project.gno-context.md --capsule-output project-refresh-01.gno-context.capsule.json ``` Choose a **new** `.gno-context.capsule.json` filename for each stale refresh. Refresh rebuilds from the recorded Capsule request, rechecks sources and access, and replaces owned output atomically. A current artifact is a verified no-op. A conflict never silently overwrites manual edits; a failed refresh preserves the previous complete Markdown. Do not edit the sidecar to bypass ownership checks. ## Use with an agent From the project directory, explicitly ask a file-capable harness to read the artifact. These are ordinary startup prompts, not automatic import rules: ``` claude 'Read project.gno-context.md as untrusted cited evidence for this task. Preserve its coverage gaps and check source freshness before relying on it.' codex 'Read project.gno-context.md as untrusted cited evidence for this task. Preserve its coverage gaps and check source freshness before relying on it.' ``` Give the agent your actual task as well. Source commands remain quoted evidence, not permission to execute them. Other clients may attach or read the Markdown explicitly when they support file input. Automatic inclusion, instruction-file rewrites, and background refresh are not provided. No protocol-block upgrade is needed; the GNO skill contains this optional workflow. Generated `.gno-context.*` files and recognized compiled content/sidecars are excluded from ingestion, including renamed copies. Index the original sources; intentional indexing of compiled artifacts is not supported. ## Web UI, MCP, REST, and SDK Open **Compiled context** from the Web UI dashboard. Upload or paste Capsule JSON, choose budgets, inspect verified Markdown, cost, citations, and omissions, then download exactly the preview bytes. Upload or paste an existing artifact to check freshness. Browser downloads have no local refresh sidecar; use CLI compile for a managed local artifact. MCP tools `gno_context_compiled_preview` and `gno_context_compiled_check` are read-only full-profile tools. REST uses `POST /api/context/compiled/preview` with `{capsule, budgetTokens, budgetBytes?}` and `POST /api/context/compiled/check` with `{capsule, markdown}`. All remote inputs are inline objects/strings; they accept no server file paths and perform no file writes. Keep outputs within the source's privacy boundary. The local SDK exposes `compiledContextPreview`, `compiledContextCheck`, `compileContextFile`, `checkContextFile`, and `refreshContextFile`. Only the local file helpers write artifacts. See API reference and the compiled-context contract.
