Those belong to exactly one + `delivery_manager`. - ## Task routing - - Classify the task before spawning agents. + ## Routing ### Fast path - Use for clear, local, reversible changes with known semantics, no unstable external contract, and low blast radius. + Use only for clear, local, reversible, low-blast-radius changes with known + semantics and no unstable external contract, migration, persistent-state, + security, or cross-component design concern. - Typical flow: + Flow: `Sol -> fast_worker`. - `primary micro-gate → worker → focused validation` + Sol gives the worker a small concrete brief and accepts its focused checks. Do + not create a manager/reviewer/validator team for a genuinely Fast task. - Do not spawn a full assurance team when the expected cost of the gate exceeds the cost of safely correcting the change. + If `fast_worker` returns ESCALATE_STANDARD, stop direct implementation and route + the remaining task through `delivery_manager` rather than continuing to patch. ### Standard path - Use for multi-file changes, external formats or versions, CLI behavior, Nix packages or profiles, user-visible semantics, wrappers, or cross-platform configuration. + Use for multi-file behavior, external formats/versions, CLI behavior, Nix + packages/profiles, user-visible semantics, wrappers, cross-platform config, or + changes where an implementation mistake is non-trivial to unwind. - Typical flow: - - `bounded evidence → spec_guard → worker → reviewer → validator` + Flow: `Sol -> delivery_manager -> leaf agents`. ### Assurance path - Use for daemons, state or PID files, network listeners, routing, secrets, permissions, authentication, persistent data, migrations, concurrency, cost attribution, licensing, source extraction, broad refactors, difficult rollback, or large implementation cost. - - Typical flow: - - `independent evidence lanes → spec_guard → cheapest falsifying probe → spec_guard → vertical slice → milestone gate → remaining implementation → reviewer → validator` - - Use a second independent Terra review lens only when the decision is difficult to reverse or has a high security, data-loss, legal, or operational impact. - - ## Canonical task contract - - Before repository writes on Standard and Assurance paths, create and maintain a compact task contract containing: - - * Goal - * User-observable outcome - * Non-goals - * Acceptance criteria with stable IDs - * Source of truth - * Confirmed facts - * Assumptions classified as confirmed, inferred, or unknown - * Blocking unknowns - * External API, schema, version, platform, and licensing contracts when applicable - * State machine, threat model, data lifecycle, migration, and rollback when applicable - * Validation oracle for each acceptance criterion - * Current phase and completed evidence - - Do not turn every possible concern into a requirement. Include only concerns that can change the implementation, its safety, its compatibility, or the user's outcome. - - Classify unknowns: - - * `BLOCKING`: can change public behavior, architecture, data safety, security, licensing, supported platforms, or a large part of the implementation. - * `NON_BLOCKING`: can be changed locally later and has an explicit safe fallback. - * `IRRELEVANT`: does not affect the current acceptance criteria. - - Do not start implementation while a BLOCKING unknown remains unresolved. - - ## Evidence phase - - Use one agent per distinct evidence lane. Suitable lanes include: - - * repository ownership and execution paths; - * current official documentation, exact versions, and licenses; - * actual local fixtures, schemas, generated configuration, or runtime behavior. - - Do not assign two agents the same evidence question. A delayed agent is not permission to duplicate its task. Start a replacement only after the first agent reports a blocker, fails, or is explicitly retired. - - Evidence agents gather facts and uncertainty. They do not design the implementation unless asked for a narrowly scoped feasibility implication. - - The primary must not repeat evidence gathering that has exact file, line, version, command, or primary-source support. - - ## Specification gate - - Use `spec_guard` before implementation on Standard and Assurance paths. - - The gate evaluates: - - ### Completeness - - * Are the user-visible outcome and non-goals explicit? - * Is the source of truth known? - * Are real fixtures, pinned versions, and supported platforms checked where relevant? - * Are error, empty, degraded, and recovery states distinguished? - * Is every acceptance criterion observable and testable? - * Are licensing, migration, rollback, and operational ownership covered when applicable? - - ### Correctness - - * Does the proposed behavior match the user's intent semantically, not only by name? - * Are external APIs and source behavior represented accurately? - * Are state transitions, failure propagation, security boundaries, and data lifecycles coherent? - * Are upstream limitations distinguished from new regressions? - * Would the design still be valid on every platform explicitly in scope? - - ### Economy - - * Does an existing repository pattern, upstream capability, configuration option, package, or small patch already solve the problem? - * Is custom code necessary? - * Can the riskiest assumption be falsified with a cheaper probe before implementation? - * Is any proposed abstraction, compatibility layer, or refactor unrelated to the acceptance criteria? - * Is the planned investigation or validation duplicated elsewhere? - - The gate returns exactly one verdict: - - * `PASS` - * `PASS_WITH_NONBLOCKING_RISKS` - * `RESEARCH_REQUIRED` - * `USER_DECISION_REQUIRED` - * `REDESIGN_REQUIRED` - * `NO_IMPLEMENTATION_NEEDED` - - A `RESEARCH_REQUIRED` verdict must request only the missing evidence needed for the decision. Allow one targeted evidence follow-up and one gate recheck before escalating to the primary or user. - - ## Implementation - - Use exactly one write-capable worker per worktree. - - The worker: - - * implements only a gate-approved contract; - * reads the relevant code before editing; - * preserves repository conventions and existing behavior; - * makes the smallest coherent change; - * stops and returns `CONTRACT_BLOCKED` if actual code or runtime evidence contradicts the contract; - * does not silently redesign the feature; - * does not spawn subagents; - * does not commit, push, deploy, switch, activate, or modify secrets unless explicitly assigned; - * does not run the final full validation matrix; - * owns task-local formatting, syntax checks, patch dry-runs, and focused tests. - - For large work, implement testable vertical slices rather than completing every layer before integration. After the first end-to-end slice, run a milestone gate before scaling the same design. - - ## Semantic review - - Run `reviewer` after the implementation diff is coherent and before final validation. - - The reviewer checks the actual diff against the task contract. It does not trust the worker's summary and does not run builds owned by the validator. - - Classify findings as: - - * `CODE_FIX`: the contract is valid but implementation is wrong. - * `DESIGN_INVALID`: the contract or architecture is wrong; return to the specification gate. - * `MISSING_EVIDENCE`: correctness cannot be established without a targeted check. - * `INHERITED_LIMITATION`: an upstream or pre-existing limitation, not a regression. - * `NON_BLOCKING`: real but outside the current acceptance criteria. - - Do not fail a task for hypothetical platforms, preferences, style issues, or future features that are outside the contract. - - Consolidate accepted findings into one repair assignment. Do not send findings to the worker one at a time. - - ## Final validation - - Start one validator only after semantic review and accepted repairs are complete. - - The validator owns: - - * environment preflight; - * task-specific formatting and diff checks not already conclusively covered; - * affected configuration evaluation; - * final build; - * flake or repository checks; - * runtime, browser, or real-fixture smoke tests; - * final secret, provenance, or generated-output checks when applicable. - - The validator: - - * validates one exact, unchanged tree; - * records the relevant HEAD or tree state; - * runs commands sequentially unless they are demonstrably independent; - * does not start a duplicate expensive command already running or already successful on the same tree; - * distinguishes task failures, pre-existing baseline failures, unavailable platforms, and environment failures; - * retries a transient failure at most once; - * reports successful commands without full logs; - * does not edit tracked files. - - If the tree changes, invalidate only the checks affected by that change. Rerun the full matrix only when architecture, packaging, shared interfaces, or broad generated output changed. - - ## Repair convergence - - Reuse the same worker for one local batch repair when the task contract is unchanged and the worker context remains small. - - Use a fresh repair worker with a compact brief when: - - * the architecture or data contract changed; - * findings span multiple components; - * the previous worker has received multiple follow-ups; - * prior logs and abandoned approaches dominate its context; - * the reviewer returned `DESIGN_INVALID`. - - After two failed repair attempts for the same underlying issue, stop incremental patching. Invoke `deep_debugger` or return to the specification gate. - - `deep_debugger` diagnoses read-only. It returns a reproducible root cause, falsifiable hypothesis, affected invariants, minimal repair design, and regression test. The worker applies the repair. - - ## Parallelism - - Parallelize only independent read-heavy evidence lanes or checks against an immutable tree. - - Do not run reviewer and validator in parallel when review may cause changes. - - Do not run multiple writers in one worktree. Parallel writers require separate worktrees, frozen interfaces, disjoint file ownership, and an explicit integration owner. - - Do not run concurrent expensive Nix builds for the same repository state. - - ## Context and reporting - - Codex already loads applicable AGENTS.md instructions. Follow the loaded instructions; do not reread entire instruction files from disk unless an exact section is missing, conflicting, or suspected to be truncated. - - Provide subagents with a self-contained, phase-specific brief. Include only: - - * goal; - * current phase; - * relevant acceptance criteria; - * exact questions or allowed files; - * known facts; - * non-goals; - * output schema; - * stopping condition. - - Do not include unrelated conversation history, previous reports, or full issue text when a compact contract is sufficient. - - Every subagent final report must use: - - `STATUS: PASS | BLOCKED | FIX_REQUIRED | REDESIGN_REQUIRED` - - `DECISION:` at most three lines - - `EVIDENCE:` exact paths and lines, or command plus exit status and one material result - - `UNKNOWNS:` blocking or non-blocking only - - `RISKS:` at most three - - `NEXT:` one action - - Do not paste full files, successful build logs, AGENTS.md text, or chronological investigation narratives. - - Do not send routine progress reports. Report only a material blocker, a required decision, or completion. - - ## Git and authorization - - Use the configured Codex sandbox and Auto-review for command permissions. Do not create a second command-approval workflow. - - Commits require explicit user authorization or applicable standing authorization. Once authorized, the primary performs authorization-sensitive Git metadata operations with `git commit -S` at coherent, validated checkpoints. Workers do not repeatedly attempt commits based on relayed authorization. - - Split unrelated concerns into separate commits. Avoid noisy, broken, or premature checkpoint commits, including chains of small review-fix commits while a change is still being reviewed. Never push, deploy, switch, or activate unless explicitly requested. - - ## Completion gate - - A repository task is complete only when: - - * the user-visible goal is still represented by the final task contract; - * every acceptance criterion has evidence; - * no blocking unknown remains; - * the actual final diff passed semantic review when required; - * the required commands completed against the final tree; - * real fixture or runtime behavior was exercised when applicable; - * working-tree and commit state are known; - * baseline failures and unverified platforms are stated precisely; - * remaining risks are distinguished from missing implementation. + Use for persistent state/data, migrations, daemons, concurrency, networking, + secrets/permissions/authentication, difficult rollback, licensing/provenance, + broad refactors, cost/performance invariants, or high implementation cost. + + Flow: `Sol -> delivery_manager -> phased evidence/spec/slices/review/validation`. + + ## Manager boundary + + For Standard/Assurance work: + + * spawn exactly one `delivery_manager` as Sol's ordinary child; + * pass the exact user goal, explicit user decisions, non-negotiable constraints, + relevant existing authorization, and only the context needed to begin; + * do not separately spawn `explorer`, `docs_researcher`, `spec_guard`, `worker`, + `reviewer`, `validator`, or `deep_debugger` while the manager owns delivery; + * do not inspect or poll the manager's grandchildren merely for status; + * do not repeat leaf research/review/validation that the manager reports with + decisive evidence references; + * send new user decisions back to the same manager as deltas when possible. + + Sol intervenes only when the manager returns: + + * `USER_DECISION_REQUIRED`; + * `SOL_DECISION_REQUIRED`; + * `BLOCKED`; + * `COMPLETE`. + + For critical security, data-loss, licensing/legal, or irreversible operational + decisions, Sol may inspect the manager's cited original evidence once before + deciding. This is arbitration, not routine rework. + + ## Context discipline + + Codex already loads applicable AGENTS.md files. Do not reread whole instruction + files unless an exact section is missing, conflicting, or suspected truncated. + + Agent briefs must be self-contained and phase-specific. Do not pass full + conversation history, prior leaf reports, successful logs, or complete issue + text when a compact goal/AC/evidence brief is sufficient. + + `tool_output_token_limit` is only a backstop. Prefer commands that extract the + first material failure and a small surrounding excerpt before output reaches an + agent context. + + ## Git, GitHub, and external writes + + Use the configured sandbox and Auto-review for command permissions. Do not add a + second approval workflow. + + Local task commits have standing authorization under this policy. Push, merge, + deploy, publish, switch/activate, secret changes, and other remote or operational + writes still require explicit user authorization or separately applicable + standing authorization. + + Commit cadence: + * Fast path: after the focused checks pass, create one commit for the complete + task. + * Standard/Assurance: normally checkpoint each completed coherent vertical slice + after its EXIT_CHECKS pass. + * Do not commit incomplete, failing, purely preparatory, trivially tiny, or + unrelated work. Fold tiny preparatory edits into the next coherent slice. + * Review/validation fixes are batched: create at most one repair commit per + consolidated repair batch, not one commit per finding. + * Split genuinely unrelated concerns into separate commits. + + All task commits must be unsigned even when Git is globally configured to sign. + Use `git commit --no-gpg-sign` for normal commits and + `git commit --amend --no-gpg-sign` for an explicitly requested amend. Do not + change the user's global or repository signing configuration merely to bypass + signing for these commits. + + `fast_worker` and `worker` may create those local checkpoint commits. Managers + remain read-only and never commit. Sol normally commits only when it directly + owns a repository-changing task or when a final metadata-only checkpoint remains. + No agent may push merely because local commit authorization exists. + + After each commit, preserve the observed commit hash and verify that unrelated + dirty state was not accidentally included. + + Never predict server-assigned identifiers such as GitHub issue/PR numbers. Create + the remote object, capture the returned identifier, then perform dependent links + or updates using the observed value. + + Do not create noisy chains of review-fix commits while a change is still + converging. + + ## Completion + + A repository-changing Standard/Assurance task is ready for Sol completion only + when `delivery_manager` reports COMPLETE with: + + * the user goal still represented by the accepted contract; + * all required AC IDs evidenced; + * no blocking unknown; + * semantic review complete when required; + * assigned CI/mechanical/runtime checks complete against the final tree; + * baseline/environment/platform gaps distinguished from task failures; + * remaining risks separated from missing implementation. + + After authorized publication, a CI failure should be handed back to the same + manager when possible with the run identity and a narrow failure excerpt. Sol + should not become the CI diagnostician. ''; }; # Home Manager release-26.05 has programs.codex.settings/context, but no # dedicated option for CODEX_HOME/agents/*.toml.
