name: x07-agent-context description: Produce deterministic, token-efficient context packs (x07 agent context) that agents can use to repair a failing X07 project. metadata: short-description: Deterministic context packs for agents version: 0.1.0 kind: docs

x07-agent-context

Use x07 agent context to generate a single deterministic artifact that captures:

• the diagnostics (focus = first severity=error, else first),
• an AST slice of the project entry at the focused diagnostic pointer,
• stable input digests for traceability.

Canonical docs:

• https://x07lang.org/docs/toolchain/agent-context/
• https://x07lang.org/docs/toolchain/repair-loop/

When to run it

Run this after a lint/check/build/run failure when you need to hand an agent the minimum closed context to fix the problem without guessing.

Minimal workflow (recommended)

1. Produce a deterministic diagnostics file (example: lint):

• x07 lint --input src/main.x07.json > .x07/lint.last.json || true

1. Build the context pack:

• x07 agent context --diag .x07/lint.last.json --project x07.json --out .x07/agent.context.json

1. Provide .x07/agent.context.json to the agent as the primary input.

Diagnostics inputs (--diag)

--diag accepts:

• raw x07diag JSON (schema_version: "x07.x07diag@0.1.0") produced by x07 lint / x07 check, or
• a tool wrapper report (schema_version: "x07.tool.*.report@0.1.0") where diagnostics[] is extracted.

Controlling slice size and closure

The pack embeds an AST slice of the project entry module at the focused diagnostic pointer. Use these knobs to trade off size vs completeness:

• --enclosure decl|defn|module (default: decl)
• --closure locals|types|imports|all (default: all)
• --max-nodes N (hard bound on slice_ast.decls)
• --max-bytes BYTES (hard bound on canonical JSON size of slice_ast)

Typical presets:

• Small, local fix: --enclosure defn --closure locals --max-nodes 40 --max-bytes 60000
• Import/type issues: --enclosure decl --closure imports --max-nodes 80 --max-bytes 120000
• Complex context: leave defaults, or bound only --max-bytes

Feeding the pack to an agent

Include:

• the context pack file,
• the exact failing command you ran,
• the desired end state (tests passing, x07 run ok, etc).

If the agent edits files, re-run the canonical loop (x07 fmt → x07 lint → x07 fix → rerun) and regenerate the pack if diagnostics move.
