Add native Codex context-budget delegation and opt-in refusal (#1140)
## What Add Codex-native `bulk-reader` and `code-writer` roles pinned to `gpt-5.6-luna`, opt-in role/config installation, and an opt-in native `PreToolUse` Bash adapter for the shared read-budget guard. Source-owned guidance and role files ship through the existing generated Codex bundle; the menu stays at 34 skills. The installed Codex 0.154 runtime can refuse covered shell calls before execution. The adapter enforces that predicate; slice discipline, target-only writes and receipt-only replies are role instructions, not an output filter or per-file sandbox. Native exact-definition hook trust remains required. ## Why Follow-up to #1137 and its [fresh author-distinct review](https://github.com/boshu2/agentops/pull/1137#issuecomment-5648513520). Correct the unverified statement that Codex has no refusal-capable hooks and provide real native delegation without subprocess model execution. This branch incorporates the isolated fixes in #1139 and targets main; land the repairs first. The fixes PR contains no Codex-native changes. Work and original acceptance are recorded in private BD `age-z25n`; `bd context --json` resolves the existing private Dolt store. [Design and live evidence](https://github.com/boshu2/agentops/blob/codex/context-budget-native/docs/design/codex-context-budget.md) records the runtime/config contracts, exact available model identifiers and published comparable rates, source paths, invocation, transcripts, accounting and limits. ## How I tested Current head: `40edb5f216b71bfa659627dca10fc0a9e04c1821`. Fresh author-distinct review: **Job2 native PASS; combined subject FAIL**. Reviewer context `01a09778-bef6-7883-880b-6764fdd783b9`, observed `gpt-6-astra`/ultra, authored no candidate code. All 52 changed paths have identical start/end manifests (SHA-256 `b1f13ca731658bc699838189f928535a386ab6de6b381b0419bb0f7ebdd88cdc`); acceptance `not_checked: []`. The native repeated-refusal naming finding is fixed and independently reproduced as resolved. Local final checks pass. [Hosted Validate CI](https://github.com/boshu2/agentops/actions/runs/34722978404) remains pending at this update; no merge is performed. Real Claude Opus follow-up closes plugin-name resolution, inherited hook invocation, complete reader coverage and observed parent/child content separation. **It also finds a remaining Claude writer failure:** two of three final workers ran their supplied check twice; a direct receipt used Markdown fences. This combined PR does not claim a full Claude writer PASS. Details, excluded failed attempts and exact identities are in the design note. - `./cli/bin/ao gate check --scope range:origin/main..HEAD`: 33 passed; the earlier unchanged registry run `./cli/bin/ao gate check --full` passed **73 gates** at `90c8b31ee` (historical receipt). `bash scripts/regen-all.sh --check`: all 11 checks passed. - Door9, hookless cold-start, doc-hook drift, shellcheck on five changed shell files, and Node syntax checks on both workflows plus the native config editor passed. - A7 Bats suites plus workflow and all native suites: **223 passed, zero skipped**. All **21 documentation-reference tests** and the strict full-document reference scan also pass after clarifying the native hook-manager terminology. - `bash tests/run-all.sh`: **10 passed, 0 failed, 1 skipped** (optional OL directory absent). This is the default static tier. - `bash scripts/validate-codex-install-bundle.sh`: passed, **34 skill packages**. Changelogs are identical; diff check clean. - Live registered reader: parent `01a09776-004f-79a0-af85-c75b472a1e68` used only spawn/wait; child `01a09776-3c38-7281-b582-01fef5101f17` was natively identified as bulk-reader/Luna/low. Six separate slices covered 1,772 lines without truncation; parent received five findings and coverage only. - Live registered writer: parent `01a09771-8908-7a00-b101-919b558cf8c1` used only spawn/wait; child `01a09771-bbbf-7232-add4-cc9ec55ad759` was code-writer/Luna/medium. Required reference, seven-line Bats target, receipt only, child check passed; coordinating parent independently ran Bats successfully without reading the target. - Live hook: native parent `01a09769-14d2-7c22-9b7d-50847de07c90`, final turn `01a09771-25f2-7830-830b-498d7ca1945e`, refused a 400-line cat before execution and allowed a three-line sed slice. Real payload is PreToolUse/Bash/tool_input.command; hashed deny ledger schema verified. An explicit session hook was trusted in `/hooks` for this proof. - Credentials-free native config/read and hooks/list probes verify personal and ordinary project discovery. Codex 0.154 reads linked-worktree project hooks from the primary checkout; `--project` now rejects linked worktrees before writing, with a real Git regression. Known failed: Claude writer check-once behavior and direct receipt fencing. Not checked: arbitrary hosted/MCP read interception; adversarial enforcement of role instructions; other runtime versions/accounts; cost savings, comparative latency or ADR-0002 value-proof clearance. Earlier reader attempts with an overlarge final slice or truncated aggregate output are disclosed and excluded from the successful coverage proof. ## Checklist - [x] `make build && make test` passes (if Go changes) — no Go changes; gate runner built once. - [x] No secrets or credentials in code - [x] Breaking changes documented — opt-in additions; unsupported linked-worktree hook installation refuses before mutation.

# Codex context-budget design and evidence
|
||||
|
||||
Status: implemented; observed runtime behavior and remaining limits below.
|
||||
Evidence cutoff: 2026-09-12. Final gate results and the remaining Claude writer failure are recorded below.
|
||||
Acceptance is the two-job caller request recorded in private BD `age-z25n`.
|
||||
The exact e32e88c verdict was written before this job began and posted at
|
||||
https://github.com/boshu2/agentops/pull/1137#issuecomment-5648513520.
|
||||
|
||||
## Installed-runtime premises
|
||||
|
||||
(a) Refusal exists. `codex --version` returned `codex-cli 0.154.0`;
|
||||
`codex features list` returned `hooks stable true` and `multi_agent stable true`.
|
||||
The original Desktop session's native session metadata reports 0.153.4,
|
||||
OpenAI `gpt-6-astra`, context `01a0974c-6f78-74c2-a43f-f0413b63ca6d`.
|
||||
The CLI is a local stdin wrapper around the installed OpenAI package; it was
|
||||
inspected and this work never invokes its noninteractive execution subcommand.
|
||||
|
||||
The [configuration reference](https://learn.chatgpt.com/docs/config-file/config-reference)
|
||||
and [hook contract](https://learn.chatgpt.com/docs/hooks#pretooluse) were fetched
|
||||
from the official documentation connector. `PreToolUse` is synchronous by
|
||||
default; exit 2 plus stderr, or a JSON `permissionDecision: deny`, refuses
|
||||
supported calls. Shell and unified exec use `Bash` / `tool_input.command`.
|
||||
Canonical common fields include session_id, cwd, hook_event_name, model,
|
||||
permission_mode and transcript_path; PreToolUse adds turn_id and tool_use_id.
|
||||
Local hooks use `~/.codex/hooks.json` or the primary checkout's
|
||||
`.codex/hooks.json`, with exact-definition trust through the native hook manager.
|
||||
Untrusted project layers and untrusted hook definitions do not run. Shell
|
||||
sandbox/approval policy also restrict operations, but is not a line-budget
|
||||
predicate. Hosted tools and some specialized paths are not intercepted, and
|
||||
write_stdin does not repeat PreToolUse for an already-running command.
|
||||
|
||||
Independent credentials-free `config/read` and `hooks/list` probes confirmed
|
||||
personal discovery and trusted ordinary-project discovery. Project trust must
|
||||
be persisted in the isolated `CODEX_HOME/config.toml`; a command-line trust
|
||||
value alone did not enable that layer. On 0.154, a linked worktree reads hooks
|
||||
from the primary checkout even though it reads agent config from the linked
|
||||
worktree. Installing hooks in both an isolated main and linked checkout returned
|
||||
only the main hook's `sourcePath`. Evidence:
|
||||
`runtime/hooks-discovery-audit.61iv_4je/linked-both-configs/result.json` under
|
||||
the external scratch directory. The installer therefore rejects `--project`
|
||||
in a linked worktree before writing anything and recommends personal install
|
||||
or running in the primary checkout. An explicit `CODEX_HOOKS_FILE` remains a
|
||||
caller-selected destination. Discovery does not itself establish hook trust.
|
||||
|
||||
`codex app-server generate-json-schema --out <scratch>/runtime/schema` also
|
||||
succeeded, exposing HooksListParams/Response and hook notifications. The live
|
||||
hook probe below checks actual invocation; the schemas alone do not prove it.
|
||||
|
||||
(b) [Custom-agent configuration](https://learn.chatgpt.com/docs/agent-configuration/subagents#custom-agents)
|
||||
uses one TOML per role in `~/.codex/agents/` or `.codex/agents/`. Required fields
|
||||
are name, description and developer_instructions. Optional model,
|
||||
model_reasoning_effort and sandbox_mode configure the spawned session.
|
||||
The name field identifies the role, not the filename. On this installed CLI,
|
||||
standalone project files did not make the name available in two live attempts
|
||||
(`01a09758-99ee-7291-9e5d-ebb4fa19560c` and
|
||||
`01a0975a-f888-73a0-bab9-d709800798fb`). Explicit
|
||||
`[agents.bulk-reader]` / `[agents.code-writer]` entries with `description` and
|
||||
`config_file` resolved the name successfully. The checkout therefore includes
|
||||
`.codex/config.toml` registrations and the installer registers both names using
|
||||
the installed runtime's `config/batchWrite` TOML editor in an isolated staging
|
||||
home. It preserves unrelated configuration and publishes only after success;
|
||||
it does not start a model session. Invoke a registered role with
|
||||
`spawn_agent(agent_type="bulk-reader", fork_turns="none", ...)`; the native
|
||||
reader proof below confirms `agent_role: bulk-reader`.
|
||||
|
||||
Spawned work has its own
|
||||
agent thread and tool transcript. Existing context may be inherited unless the
|
||||
caller requests a fresh context; this Desktop facade exposes fork_turns=none.
|
||||
The same facade has no agent_type parameter, so an explicit role-prompt fallback
|
||||
is documented without claiming implicit role discovery or sandbox application.
|
||||
`codex debug prompt-input` emits messages without tool schemas; absence of role
|
||||
names there does not establish whether custom-role discovery works.
|
||||
|
||||
(c) `codex debug models` refreshed the following native catalog. Visibility is
|
||||
reported verbatim; hidden entries are not ordinary selectable task models.
|
||||
The Desktop spawn schema separately exposes Astra, Sol, Terra, Luna and 5.5;
|
||||
the app task-creation contract also lists Spark. This work uses no task-creation
|
||||
API or substitute headless model process.
|
||||
|
||||
| Identifier | Catalog visibility | Runtime description |
|
||||
|---|---|---|
|
||||
| `gpt-6-astra` | list | Our most capable model for complex, demanding work. |
|
||||
| `gpt-reserve` | hide | Fast and affordable agentic coding model. |
|
||||
| `gpt-5.6-sol` | list | Reliable agentic workhorse for everyday tasks. |
|
||||
| `gpt-5.6-terra` | list | Balanced agentic coding model for everyday work. |
|
||||
| `gpt-5.6-luna` | list | Fast and affordable agentic coding model. |
|
||||
| `gpt-5.5` | list | Proven previous-generation model for coding and general work. |
|
||||
| `gpt-5.3-codex-spark` | list | Ultra-fast coding model. |
|
||||
| `codex-auto-review` | hide | Automatic approval review model for Codex. |
|
||||
|
||||
Selected: `gpt-5.6-luna`, low effort for reading, medium for writing. The catalog
|
||||
calls it fast and affordable. The fetched [official rate card](https://learn.chatgpt.com/docs/pricing#token-rates)
|
||||
lists input/cached/output credits per million tokens: Luna 5/0.5/30,
|
||||
Terra 50/5/300, Sol 100/10/500, Astra 250/25/1250, and 5.5 125/12.5/750.
|
||||
Spark is a research preview without a comparable rate. Thus Luna is the cheapest
|
||||
listed candidate with published comparable rates; hidden entries and unpriced
|
||||
preview models do not establish a cheaper general reader. Adequacy is checked
|
||||
by the live reader/writer tasks below, not inferred solely from the description.
|
||||
The catalog itself contains no pricing; no account-specific charge is claimed.
|
||||
|
||||
## Three layers
|
||||
|
||||
Delegation source: `skills/agent-native/agents/bulk-reader.toml` and
|
||||
`code-writer.toml`, mirrored by `scripts/regen-all.sh` into the existing Codex
|
||||
skill bundle. `.codex/agents/` points to those sources, and `.codex/config.toml`
|
||||
registers both names for checkout use.
|
||||
`scripts/install-codex-context-agents.sh` copies the generated templates for
|
||||
personal or project use, preserving changed roles and config with unique
|
||||
backups. It requires Node and an installed Codex with `config/batchWrite`. The
|
||||
removed `scripts/install-codex.sh` remains a tombstone. The plugin manifest
|
||||
continues shipping `./skills-codex`; no new skill or automatic hook wiring.
|
||||
Source guidance is shared, so the existing parity_only catalog treatment is
|
||||
retained rather than inventing an override or editing generated twins.
|
||||
|
||||
Enforcement: `scripts/install-codex-read-budget-guard.sh` and the
|
||||
opt-in `skills/cc-hooks/hooks/codex-read-budget-guard.sh` adapter reuse the same
|
||||
read-budget predicate, waiver controls, sentinel behavior and hashed telemetry.
|
||||
The installer leaves hook trust to Codex. Only verified canonical Bash input is
|
||||
wired; no invented Read/read_file mapping. Rule scope and known fail-open cases
|
||||
are the shared shell guard's contract. This can refuse covered shell calls,
|
||||
but it is not comprehensive protection against arbitrary reads.
|
||||
|
||||
Advisory: `skills/agent-native/SKILL.md` and its
|
||||
`references/context-budget-delegation.md` explain when/how to delegate, slices,
|
||||
required references, fresh contexts and receipts. Reader read-only and writer
|
||||
workspace-write are role defaults; parent live overrides can supersede them.
|
||||
Target-only writes and content-free child replies are role instructions, not
|
||||
output filtering or dynamic per-file confinement. Check output stays in the
|
||||
child; the parent receives status only. A dead child means unknown side effects.
|
||||
Native transcripts persist according to the runtime; no 10–30 second latency
|
||||
or 90% savings claim is made for this implementation.
|
||||
|
||||
## Live proofs
|
||||
|
||||
Evidence files below live under the external scratch directory
|
||||
`/tmp/agentops-context-budget.TWbdWl/live-proof`; native transcripts remain under
|
||||
`~/.codex/sessions/2026/09/12/`. Raw transcripts and private tracker data are not
|
||||
copied into Git. Quoted receipts contain summaries and metadata only.
|
||||
|
||||
### Reader: observed parent/child separation
|
||||
|
||||
Interactive command, with the concrete checkout path substituted for `$REPO`:
|
||||
|
||||
```sh
|
||||
codex --no-alt-screen \
|
||||
-c 'agents.bulk-reader.description="Read one large file in slices; return findings only"' \
|
||||
-c 'agents.bulk-reader.config_file="/tmp/agentops-context-budget.TWbdWl/native/skills/agent-native/agents/bulk-reader.toml"' \
|
||||
-C "$REPO" '<delegate a question about tests/scripts/probe-skill.bats; parent must not read it>'
|
||||
```
|
||||
|
||||
This was an actual interactive CLI session. The prompt asked which behaviors
|
||||
`tests/scripts/probe-skill.bats` verifies, required six separate tool invocations
|
||||
with at most 350 lines each, and prohibited parent reads. Parent transcript
|
||||
`01a09776-004f-79a0-af85-c75b472a1e68` contains only `spawn_agent` and two
|
||||
`wait_agent` calls. Spawn requested `agent_type: bulk-reader`, `gpt-5.6-luna`
|
||||
and `fork_turns: none`; returned identity `/root/probe_skill_reader`.
|
||||
|
||||
Child native metadata `01a09776-3c38-7281-b582-01fef5101f17` records that parent,
|
||||
`agent_role: bulk-reader`, model `gpt-5.6-luna`, effort `low`. Its six tool calls
|
||||
contain respectively the `sed -n` ranges `1,350p`, `351,700p`, `701,1050p`,
|
||||
`1051,1400p`, `1401,1750p`, `1751,1772p`. Transcript inspection found zero
|
||||
truncation markers in all six responses. Its reply contained five `{ref,text}`
|
||||
findings and `"lines_covered":1772,"complete":true`; no file dump entered
|
||||
the parent. Example: `tests/scripts/probe-skill.bats:200-407` — verifies replay
|
||||
provenance, immutable metadata, transcript integrity and drift handling.
|
||||
|
||||
Native cumulative token accounting (input includes cached input):
|
||||
|
||||
| Session | Input | Cached input | Output | Total | Duration |
|
||||
|---|---:|---:|---:|---:|---:|
|
||||
| Reader parent | 105,760 | 91,520 | 897 | 106,657 | 59,608 ms |
|
||||
| Reader child | 293,281 | 249,088 | 840 | 294,121 | 27,856 ms |
|
||||
|
||||
These are cumulative request tokens including instruction/bootstrap overhead,
|
||||
not unique context occupancy or measured savings. Native context-window capacity
|
||||
was 258,400. No direct-read control run or cost reduction is claimed.
|
||||
Two earlier reader attempts are excluded from the successful coverage proof:
|
||||
the facade attempt ended with a 372-line slice; registered child
|
||||
`01a09761-5d5e-7ff0-8471-bcee884315fd` combined six valid slices into one response
|
||||
that was truncated without a complete reread. The latter also self-reported an
|
||||
incorrect generic model identity. Those failures motivated the source role's
|
||||
one-slice-per-invocation instruction. Model claims above use native metadata,
|
||||
not self-report; parent/child separation alone never proves full coverage.
|
||||
|
||||
### Writer: observed receipt-only completion
|
||||
|
||||
The interactive CLI was started with explicit `agents.code-writer.description`
|
||||
and `agents.code-writer.config_file` pointing to the source template, just as
|
||||
in the reader invocation. The prompt required exactly one native child with
|
||||
`agent_type: code-writer`, Luna, fresh context, one test target and a required
|
||||
reference. Parent `01a09771-8908-7a00-b101-919b558cf8c1` called only `spawn_agent`
|
||||
and `wait_agent`; it never read a file. Required reference:
|
||||
`tests/scripts/codex-context-agents.bats`. Task: create a standalone Bats test
|
||||
that checks `printf` produces the exact string `native-ready`.
|
||||
|
||||
Child `01a09771-bbbf-7232-add4-cc9ec55ad759` records that parent,
|
||||
`agent_role: code-writer`, observed `gpt-5.6-luna`, effort `medium`.
|

It wrote the target, ran `bats` once and returned this receipt:
|

||||
```json

|
||||
```
|
||||
|
||||
The coordinating Desktop parent independently ran `bats <target> >
|
||||
<scratch>/registered-parent-check.log 2>&1`, exit 0, without reading the target.
|
||||
Transcript extraction inspected call names, accounting and the final receipt;
|
||||
it did not import child write payloads or generated source into either parent.

|
||||
|
||||
These totals have the same cumulative-accounting limitation as the reader table.
|
||||
The earlier Desktop facade fallback also completed a seven-line Bats file and
|
||||
passed its check (`01a0975d-e448-70a2-8d24-18d6c188dd26`, Luna/medium,
|
||||
`agent_role: null`); it is not used to claim named-role discovery.
|
||||
|
||||
### Hook: actual synchronous refusal
|
||||
|
||||
After `bash scripts/install-codex-read-budget-guard.sh --project`, a temporary
|
||||
wrapper captured the native payload for one controlled synthetic file and
|
||||
forwarded it to the installed adapter. The interactive CLI was launched with
|
||||
an explicit session `hooks.PreToolUse` definition matching `^Bash$`, command
|
||||
`bash <scratch>/capture-hook.sh`, timeout 10. Its exact definition was reviewed
|
||||
and trusted in the native hook manager; existing user hook settings were not
|
||||
enabled or disabled.
|
||||
Native parent: `01a09769-14d2-7c22-9b7d-50847de07c90`.
|
||||
|
||||
The actual captured input included `hook_event_name: PreToolUse`,
|
||||
`tool_name: Bash`, `tool_input.command`, `cwd`, `model: gpt-6-astra`,
|
||||
`session_id`, `turn_id` and `tool_use_id`. A 400-line fixture was used:
|
||||
`cat <scratch>/large-proof.txt` was refused before execution;
|
||||
`sed -n '1,3p' <scratch>/large-proof.txt` succeeded with exit 0 and three lines.
|
||||
No retry or waiver was used. The initial turn was
|
||||
`01a0976a-5f04-7c13-ae51-704b1f783399`. The final shared guard was reinstalled
|
||||
and the same pair rerun after repairs in turn
|
||||
`01a09771-25f2-7830-830b-498d7ca1945e` (again denied / exit 0);
|
||||
its source and installed SHA-256 both
|
||||
were `c5a4c73598c7eed1e2b058534c309f96b7c77dd4e6baf4409b2f62e5724f6590`.
|
||||
|
||||
The deny ledger contains one hashed entry per denied call: policy
|
||||
`core.context:unbounded-read`, `tool: Bash`, `lines: 400`, `budget: 350`,
|
||||
`mode: deny`, `decision: deny`, a SHA-256 path, timestamp and session ID.
|
||||
It contains no raw path or command; allowed slices add no line. The separate
|
||||
explicit proof capture contains synthetic command metadata solely to verify
|
||||
the real runtime shape and is not the product telemetry stream.
|
||||
|
||||
## Claude live follow-up
|
||||
|
||||
On 2026-09-12 the caller explicitly authorized native Claude Opus sessions.
|
||||
The installed CLI was 2.1.263; `--model opus` resolved in native init metadata
|
||||
to `claude-opus-5`. The source workflows and plugin agents selected Haiku;
|
||||
native child envelopes reported `claude-haiku-4-5-20251001`. Each fixture run
|
||||
used a separate parent session, an external temporary working directory,
|
||||
explicit tool permissions, no inherited MCP configuration, a 300-second
|
||||
wall limit and a 2 MiB combined output limit. These are bounded test conditions,
|
||||
not shipped runtime limits or claimed typical latency. Runtime transcripts
|
||||
remain private outside Git under the native Claude session store.
|
||||
|
||||
Real plugin registration requires `agentops:bulk-reader`,
|
||||
`agentops:code-writer`, `agentops:bulk-read` and `agentops:code-write`.
|
||||
Bare names failed. Shared Claude advice now uses the registered names;
|
||||
Codex advice keeps its native `bulk-reader` name on first and repeated denial.
|
||||
Standalone names are appropriate only when that runtime actually lists them.
|
||||
|
||||
Hook parent `663916c8-8a83-4c94-97dc-d152b65b91c0` made four real calls:
|
||||
an unbounded Read was refused, a repeat received the short refusal, a one-line
|
||||
Read succeeded, and an unbounded Bash cat was refused. Exactly three hashed
|
||||
ledger entries recorded 1,105 lines and budget 100; allowed reads were silent.
|
||||
Actual hook inputs include child agent and tool-use identities, which match
|
||||
the reader and writer child transcripts. This closes the hook-inheritance gap.
|
||||
|
||||
Reader parent `e075d6ee-5e6c-4a9a-bced-f8b04c8c62b1` invoked one direct
|
||||
`agentops:bulk-reader` and one native `agentops:bulk-read` workflow. The direct
|
||||
child `abea59d59d07ca070` and workflow child `a20371eed359e8342` each read
|
||||
12 slices at offsets 1, 101, through 1101, with limit 100. Independent transcript
|
||||
comparison verified all 1,105 real lines exactly once, zero citation mismatches,
|
||||
and correct decision references 10, 560 and 1095. Both returned complete
|
||||
coverage of 1,105 lines; the missing-file child returned zero and incomplete.
|
||||
The parent called only Agent, Workflow and TaskOutput. Its native transcript
|
||||
contains no source-only sentinel. The CLI stream multiplexes child events with
|
||||
`parent_tool_use_id`; those observable child events are not parent model input.
|
||||
|
||||
Writer parent `4b97e6e7-8620-4319-b94e-a10216cccddc` ran the native
|
||||
`agentops:code-write` workflow for `eta.bats` and `theta.bats` and a direct
|
||||
`agentops:code-writer` for `iota.bats`. All three measured physical line counts
|
||||
with the requested metadata-only awk command; actual files and receipts each
|
||||
contain seven lines. Independent Bats checks passed for all three files, with
|
||||
unchanged before/after digests. The fixture inventory gained only the three
|
||||
assigned targets; all prior files stayed unchanged. Parent calls were only
|
||||
Workflow, Agent and TaskOutput. Independent transcript comparison found no
|
||||
complete child write payload, raw check output or source/check sentinel in the
|
||||
native parent context. The shared source in this run is fixes commit
|
||||
`53bcfec1480c205290f286b4a7ccd582216eb6f9`.
|
||||
|
||||
**Remaining observed failure:** eta and iota each invoked the supplied check
|
||||
twice, while theta invoked it once. The fixture's independent invocation ledger
|
||||
and native child tool IDs agree. This violates the source instruction to run the
|
||||
check once; measured line counts and passing tests do not clear that failure.
|
||||
Direct iota also wrapped its metadata JSON receipt in Markdown fences despite
|
||||
the requested plain JSON format. The writer has therefore not established the
|
||||
complete requested one-shot behavior in these live runs. Do not interpret the
|
||||
successful reader/native Codex evidence as a full Claude writer PASS.
|
||||
|
||||
Earlier attempts are preserved and excluded: a direct reader stopped after
|
||||
one slice; a zero-based workflow reader mislabelled its first slice and counted
|
||||
an EOF display line; writer permissions initially denied fixture operations;
|
||||
writers returned absolute paths for relative receipt identities; one direct
|
||||
writer copied a test-success line; two workflow writers estimated eight lines
|
||||
for seven-line files. These findings prompted explicit one-based continuation,
|
||||
per-item receipt identity constraints, status-only receipts and an actual
|
||||
post-write line-count command. A fenced JSON receipt observed in a direct
|
||||
agent reply illustrates that direct-role formatting remains an instruction.
|
||||
No byte-filtering or strict direct-agent output parser is claimed.

|

|

## Model selection belongs to the caller
|
||||
## Codex native roles and enforcement
|
||||
|
||||
`haiku` is the default for both delegations; the caller may pin another model
|
||||
per call (`model` in the workflow args, or the subagent's `model` field). Codex
|
||||
has no PreToolUse hooks, so only the delegation layer applies there: dispatch a
|
||||
fresh cheap `codex exec` per [codex-exec](../../codex-exec/SKILL.md) with the
|
||||
same reader or writer prompt. [model-dispatch](model-dispatch.md) still governs
|
||||
judgment legs; a reader or writer is an execution role, never a judge.
|
||||
Verified against installed `codex-cli 0.154.0` on 2026-09-12 (the authoring
|
||||
Desktop session reports 0.153.4). Codex has synchronous `PreToolUse` hooks that
|
||||
can refuse supported local tool calls with exit 2 and stderr. Shell tools,
|
||||
including `exec_command`, arrive as `tool_name: "Bash"` and
|
||||
`tool_input.command`. This replaces the previous unverified assertion that
|
||||
Codex had no such hook. [Codex hook contract](https://learn.chatgpt.com/docs/hooks).
|
||||
|
||||
The Codex guard is an optional installation from the checkout:
|
||||
|
||||
```sh
|
||||
bash scripts/install-codex-context-agents.sh # personal roles
|
||||
bash scripts/install-codex-read-budget-guard.sh # optional shell guard
|
||||
# Add --project for project scope; see the linked-worktree limit below.
|
||||
```
|
||||
|
||||
Restart Codex to load the roles, and review the exact hook in `/hooks` before
|
||||
trusting it. Installing files does not activate an untrusted hook. The guard is
|
||||
inert in the plugin and its default hook manifest remains unchanged. The
|
||||
0.154 CLI resolves project hooks from the primary checkout even when launched
|
||||
in a linked worktree. The hook installer rejects `--project` there before
|
||||
writing anything; install personally or run it in the primary checkout.
|
||||
Project trust must be saved in Codex config, and does not replace hook trust.
|
||||
The Codex installer wires only the verified Bash shape. It does not claim coverage
|
||||
of arbitrary MCP reads, hosted tools, or tool paths that opt out of hooks.
|
||||
It uses the same policy `core.context:unbounded-read`, budget
|
||||
`AOP_READ_BUDGET_LINES` (350 by default), waivers and hashed telemetry ledger
|
||||
as the Claude guard. Pipes, redirects, unresolved shell expressions and other
|
||||
command words remain outside the predicate. This is a scoped guardrail, not a
|
||||
complete boundary against all ways to read a file.
|
||||
|
||||
The role templates are canonical source files under this skill's `agents/`
|
||||
directory, mirrored into `skills-codex/agent-native/agents/` by regeneration.
|
||||
The checkout exposes them at `.codex/agents/` using relative symlinks; the
|
||||
installer copies the generated templates to the runtime's personal or project
|
||||
agent directory and registers `agents.<name>.description` and `config_file`
|
||||
using the installed Codex config editor. The checkout has equivalent explicit
|
||||
registrations in `.codex/config.toml`; standalone file discovery did not work
|
||||
in the measured CLI, while registered roles ran successfully. Installation
|
||||
requires Node and the installed Codex runtime. They do not add skills to the
|
||||
34-skill menu.
|
||||
|
||||
- `bulk-reader` (`agents/bulk-reader.toml`): one question and one file, slices
|
||||
of at most 350 lines (or a smaller configured budget), up to 40 paraphrased
|
||||
`path:line` findings with truthful coverage. Default sandbox: read-only.
|
||||
- `code-writer` (`agents/code-writer.toml`): spec, required reference and one
|
||||
target; patterned write and optional check, receipt only. Default sandbox:
|
||||
workspace-write. Target-only edits and content-free returns are role
|
||||
instructions; they are not a per-file sandbox or output filter. Parent live
|
||||
sandbox overrides can also override a role's default sandbox.
|
||||
|
||||
Ask Codex: "Use bulk-reader to answer <question> about <path>; return at most
|
||||
five findings and coverage. Keep the file out of this parent context."
|
||||
For a write: "Use code-writer with spec <spec>, reference <path>, target
|
||||
<path>, check <read-only check>; return the receipt only."
|
||||
The runtime identifies a custom agent by its TOML `name`. When its native
|
||||
spawn tool exposes `agent_type`, select that name. On a facade that exposes
|
||||
only a task name, message, model and context inheritance, pass the role's
|
||||
instructions to a fresh child, explicitly select `gpt-5.6-luna` and the role's
|
||||
effort, and disable history inheritance (`fork_turns: "none"`). That fallback
|
||||
is a native delegated prompt; do not claim that the facade loaded a named role
|
||||
or enforced its sandbox setting. Never replace either route with a subprocess
|
||||
model invocation. [Codex subagent contract](https://learn.chatgpt.com/docs/agent-configuration/subagents).
|
||||
|
||||
The parent checks only coverage, locators and receipt metadata. If evidence is
|
||||
insufficient, delegate a follow-up or let a fresh validator inspect the result
|
||||
in its own context. Do not read the whole file back into the parent to verify
|
||||
that delegation worked. Native output truncation is not proof of complete
|
||||
coverage; the reader retries smaller slices or returns `complete: false`.
|
||||
|
||||
## Model selection
|
||||
|
||||
Claude agents and Workflow conveyors default to `haiku`; workflow `model` may
|
||||
override it. The Codex roles pin `gpt-5.6-luna` (reader low effort, writer medium),
|
||||
a model available in the measured runtime's catalog and the least expensive
|
||||
listed model with published comparable credit rates at this cutoff. Spark's
|
||||
research-preview price is not a comparable published rate. Role model pins and
|
||||
availability should be rechecked for another account or release; do not silently
|
||||
substitute a costly model. [Current rate card](https://learn.chatgpt.com/docs/pricing#token-rates).
