 380. **Top-level `tokens --help --output-format json` hangs with zero stdout/stderr instead of returning bounded command help JSON** — dogfooded 2026-04-30 for the 02:30 nudge on current `origin/main` / rebuilt `./rust/target/debug/claw` with embedded `git_sha` `d95b230c`. After verifying #358 covered `cost --help`, a fresh adjacent probe on the token-budget surface showed the same silent failure class: repeated bounded runs of `timeout 8 ./rust/target/debug/claw tokens --help --output-format json` exited `124` with `stdout=0` and `stderr=0`. In the same rebuilt binary, `version --output-format json` returned promptly with version/build metadata, proving the binary itself and JSON output path are reachable. This is distinct from #358's cost help hang: the affected surface is the sibling `tokens` command help, which agents use before estimating prompt/session token budgets. **Required fix shape:** (a) make `tokens --help --output-format json` return static/bounded stdout JSON with `kind:"help"` or `kind:"tokens"`, `action:"help"`, usage, options, examples, supported output formats, and related slash/direct commands; (b) ensure help rendering does not initialize slow token accounting, session, or provider state; (c) if any dynamic provider is consulted, return a typed JSON timeout/unavailable error instead of hanging; (d) add regression coverage proving tokens help in JSON mode returns within a deterministic budget. **Why this matters:** token budgeting is a preflight clawability surface. If help hangs silently, automation cannot safely discover how to inspect or constrain token usage before running expensive prompts, and budget-aware wrappers stall at the discovery step.

 381. **Top-level `cache --help --output-format json` hangs with zero stdout/stderr instead of returning bounded command help JSON** — dogfooded 2026-04-30 for the 03:00 nudge on current `origin/main` / rebuilt `./rust/target/debug/claw` with embedded `git_sha` `d95b230c`. After #358 and #380 landed for the cost/tokens preflight help hangs, a fresh adjacent probe on the cache-control surface showed the same silent failure class: repeated bounded runs of `timeout --kill-after=1s 8s ./rust/target/debug/claw cache --help --output-format json` exited `124` with `stdout=0` and `stderr=0`. In the same rebuilt binary, `version --output-format json` returned promptly with version/build metadata, proving the binary itself and JSON output path are reachable. This is distinct from the separate `/cache` slash-command envelope mismatch class: the affected surface here is top-level `cache` command help, where agents need bounded local discovery before deciding whether to inspect, clear, or summarize cache state. **Required fix shape:** (a) make `cache --help --output-format json` return static/bounded stdout JSON with `kind:"help"` or `kind:"cache"`, `action:"help"`, usage, options, examples, supported output formats, and related slash/direct commands; (b) ensure help rendering does not initialize slow cache/session/provider state; (c) if any dynamic provider is consulted, return a typed JSON timeout/unavailable error instead of hanging; (d) add regression coverage proving cache help in JSON mode returns within a deterministic budget. **Why this matters:** cache inspection and cleanup are recovery/control-plane operations. If cache help hangs silently, claws cannot safely discover cache semantics before attempting cleanup, and automation stalls before it can choose a non-destructive cache action.

-413. **`acp --output-format json` leaks internal ROADMAP tracking numbers and implementation notes as top-level JSON fields — `discoverability_tracking:"ROADMAP #64a"` and `tracking:"ROADMAP #76"` are internal backlog references that should not appear in the public machine-readable contract** — dogfooded 2026-04-30 by Jobdori on `e939777f`. Running `claw acp --output-format json` returns a ten-key envelope: `aliases`, `discoverability_tracking`, `kind`, `launch_command`, `message`, `recommended_workflows`, `serve_alias_only`, `status`, `supported`, `tracking`. Two fields are verbatim internal backlog cross-references: `"discoverability_tracking":"ROADMAP #64a"` and `"tracking":"ROADMAP #76"`. These were presumably used during initial scaffolding to track which backlog items the stub relates to, but they are now part of the public JSON contract that automation consumes. The `message` field also contains implementation-note prose (`"ACP/Zed editor integration is not implemented in claw-code yet. \`claw acp serve\`..."`) that describes the build state rather than the command's machine-readable status. **Required fix shape:** (a) remove `discoverability_tracking` and `tracking` from the public JSON envelope or move them to an optional `_debug` or `_meta` sub-object gated on a debug flag; (b) replace `message` prose with a structured `reason` enum (`"not_implemented"`, `"discoverability_only"`, `"serve_only"`) plus optional `detail` string; (c) rename `supported:false` + `status:"discoverability_only"` to a single typed `availability` object with `status`, `reason`, and `target_command` fields; (d) add regression coverage proving the public `acp --output-format json` envelope contains no internal tracking/backlog fields and that `message` is not the sole machine-classifiable signal. **Why this matters:** public JSON APIs should not leak internal ticket references. Automation that snapshots or validates the ACP JSON schema will embed these internal identifiers into external contracts and need to change every time backlog numbering shifts.

+415. **`config <section> --output-format json` returns `merged_keys:int` (a count) with no actual merged key-value pairs — automation cannot read the resolved configuration values from JSON** — dogfooded 2026-04-30 by Jobdori on `e939777f`. Running `claw config env --output-format json`, `claw config model --output-format json`, or `claw config hooks --output-format json` all return an identical five-key envelope: `{"cwd":"...","files":[...],"kind":"config","loaded_files":2,"merged_keys":1}`. The `merged_keys` field is an integer count of how many keys were merged across the loaded files, not an object or array of the actual key names and resolved values. The `files` array shows which config files were loaded/missing but contains no per-file key-value content. The merged section content — the actual resolved `env`, `model`, or `hooks` configuration — is entirely absent from the JSON output. It only appears in the prose output as a "Merged section: env / <value>" block. **Required fix shape:** (a) add a `merged` or `resolved` object/array field to the JSON envelope containing the actual key-value pairs that resulted from merging the loaded config files for the requested section; (b) rename `merged_keys` from an integer count to either remove it (derivable from `len(merged)`) or keep it as a companion count field; (c) for each entry in `merged`, include `key`, `value`, and optionally `source_file` so automation can attribute which file contributed the value; (d) add regression coverage proving `config env --output-format json` with a non-empty env section populates `merged` (or equivalent) with the actual resolved key-value pairs. **Why this matters:** the entire purpose of `config env/model/hooks --output-format json` is to allow automation to read the resolved runtime configuration without screen-scraping prose. Returning only a count defeats the purpose and forces callers to either re-parse the prose output or re-read and merge the source config files themselves.
