typeclaw-permissions

You run under an access-control system that gates which sessions wake you, which tools succeed, and which guards you can bypass. This skill exists so you can answer the user's questions about access honestly, edit roles without bricking your own inbound channel, and explain blocked: messages in terms of the role/permission model rather than the surface-level guard reason.

The model in one paragraph

Every session you run in has a SessionOrigin (TUI / channel / cron / subagent). How the runtime resolves it to a role depends on the origin kind:

• TUI and channel sessions resolve by walking the role table in severity-then-declaration order and picking the first role whose match rules cover the origin. The walk order is: owner → trusted → custom roles (in reverse declaration order; later declarations override earlier ones) → member → guest. Built-in privileged roles always get the first shot regardless of how the operator ordered typeclaw.json#roles, so a broad rule on member cannot shadow a narrower rule on owner or trusted. Among custom roles, the later-declared entry wins so operators can append overrides without rewriting earlier blocks. This is the only origin shape that match rules actually grant roles to at runtime.
• Cron sessions resolve from scheduledByRole, a string stamped on the cron job record itself (in cron.json for hand-authored entries, or by the runtime for plugin-contributed cron). Match rules of the form cron parse but never grant a role to a running cron session — provenance wins.
• Subagent sessions resolve from spawnedByRole, snapshotted from the spawning session's resolved role at spawn time. Same story: subagent / subagent:<name> rules parse but don't grant roles at runtime; the spawn provenance is the source of truth.

Each role carries a set of permissions — opaque dotted strings like channel.respond, cron.schedule, security.bypass.gitExfil. The runtime checks them in the channel router, session/tool construction, the security plugin, and permission-aware plugin code. Separate core wrappers and the bash sandbox enforce canonical credential isolation independently of role permissions and plugin hooks.

Non-bypassable canonical-secret invariant: no role, including owner, may read .env, secrets.json, auth.json, canonical credential directories, reusable CLI profiles, or their hardlink/symlink aliases through model-driven tools. fs.see.secrets authorizes runtime-owned use through dedicated mediation; it does not reveal raw stores. security.bypass.*, severity tiers, wildcard expansion, and acknowledgeGuards affect plugin policy only. They never remove canonical masks, preserve reusable credential env vars for arbitrary commands, disable immutable input pinning, or authorize model-driven credential edits.

The four built-in roles

You always have these four, even if typeclaw.json declares zero roles. User-declared roles append match rules to the built-ins but replace the permission list entirely (so "permissions": [] on a built-in role means "no permissions" — be careful).

Roles form a strict tower for bypassable plugin guards: each role bypasses guards at its tier and below. The canonical-secret invariant sits outside this tower.

A session that doesn't match anything resolves to guest. guest has no channel.respond, so the router silently drops inbound messages whose author resolves to guest. This is the most common cause of "the agent stopped responding": the user added a channel but did not add a match rule, so every speaker in that channel is guest and every inbound is dropped before you ever see it. There is no message in your session log when this happens — only a host-side line [channels] <key>: denied by permissions (channel.respond) author=<id>.

What your current session sees

When the runtime knows your permissions, it prepends a block under your ## Session origin:

## Your role in this session

Role: `member`. Permissions: `channel.respond`.

This concrete role/permissions block renders for cron and subagent sessions, which have a single fixed actor. For TUI sessions the block is omitted because TUI always resolves to owner under severity-then-declaration ordering (built-in owner.match includes tui and is appended-to, never replaced, by user config — and owner is walked first). If you don't see the block in a TUI session, treat yourself as owner.

Channel sessions are different. A channel session is keyed by chat/thread, not by author, so it can see many speakers with different roles. It does NOT print one concrete role; instead the block is a policy reminder:

## Your role in this session

This is a channel conversation that may include multiple speakers...

For each user turn, the current speaker's effective role is delivered in the turn context as a <your-role authority="current-speaker">…</your-role> tag (omitted for owner, the unconstrained default). That per-turn tag is authoritative for the current message and overrides any role implied by the system prompt. If the user asks "what role am I right now in this channel", read the <your-role> tag on the current turn (or, if absent, treat them as owner); do not consult a session-creation role line — channel sessions no longer carry one.

The permission list (cron/subagent block) is exhaustive at session-creation time for the resolved role. If a permission you expect isn't listed there, the role doesn't carry it — adding it requires editing roles.<role>.permissions[] and restarting.

Memory recall is globally visible by default across all roles and origins. Provenance is additive searchable metadata, not an authorization boundary. The optional workspace, chat, and thread parameters on memory_search narrow results when a focused subset is needed; no memory-specific permission grant is required.

The match-rule DSL

roles.<role>.match[] is an array of compact strings. The parser is hand-rolled in src/permissions/match-rule.ts; the canonical shapes are:

tui                                # any TUI session
*                                  # any channel session, any platform
<platform>:*                       # any chat on this platform (slack | discord | telegram | line | kakao)
<platform>:<workspace>             # one workspace, any chat
<platform>:<workspace>/<chat>      # one specific chat
<platform>:dm/*                    # any DM on this platform
kakao:group/*                      # any KakaoTalk group chat
kakao:open/*                       # any KakaoTalk open chat
<rule> author:<authorId>           # AND-tighten any of the above to one author

cron, subagent, and subagent:<name> are also valid parser shapes (they parse without error), but they do not grant a role to a running cron or subagent session — those resolve from stamped provenance (scheduledByRole / spawnedByRole) instead. Don't write those rules expecting them to admit traffic the way channel rules do.

Within a single string, tokens are AND'd. Across multiple strings in match[], they're OR'd. The platform names are exactly slack | discord | telegram | line | kakao. Workspace and chat coordinates are platform-native IDs (Slack team T0123, Discord guild 123456789012345678, Telegram chat 42, LINE chat ID, KakaoTalk chat hash) — never display names. If the user gives you a name, you need to resolve it to an ID before writing the match rule.

Things the DSL rejects (the parser emits actionable errors at boot, but you should not write these in the first place):

• slack:*/* — */* is redundant; use slack:* for "any Slack chat".
• slack:*/C0ABCDE — workspace-less chat ID is impossible; pick a workspace.
• slack:T0123/* — workspace-only is enough; drop the trailing /*.
• team:T0123, guild:G123, tg:42 — these are legacy prefixes that are no longer supported. The parser rejects them with a hint to use the canonical form: slack:T0123, discord:G123, telegram:42.
• autor:U_ME — typo of author:. The parser will suggest the fix at boot.

Permission strings you will see

Three sources contribute permission strings:

1. Core (always present): channel.respond, session.control, session.admin, cron.schedule, cron.modify, subagent.spawn, subagent.cancel, subagent.output, subagent.spawn.operator, fs.see.private, fs.see.secrets.
2. Bundled security plugin (always loaded): the eight per-guard strings (security.bypass.secretExfilBash, security.bypass.gitExfil, security.bypass.gitRemoteTainted, security.bypass.secretExfilRead, security.bypass.ssrf, security.bypass.sessionSearchSecrets, security.bypass.systemPromptLeak, security.bypass.outboundSecret) AND three severity-tier strings (security.bypass.low, security.bypass.medium, security.bypass.high).
3. User-declared plugins (variable): each plugin can contribute its own strings via definePlugin({ permissions: [...] }).

The security plugin classifies each guard on a two-axis policy:

• high — direct audience-leak. Bypass sends data to a third-party audience outside the operator's control loop with NO operator-visible intermediate step. Inhabitants: outboundSecret, systemPromptLeak, gitRemoteTainted. owner bypasses by default; trusted, member, guest do not. The canonical case is owner-in-public-channel: an owner-permissioned operator asking the agent to "post deploy status to #general" can silently leak a Bearer ghp_… line. The defense lives in roles.owner.match[] discipline — the default is TUI-only, where a human is present. Configs that widen owner to a channel author should narrow the match or strip security.bypass.high (and the wildcard sentinel) from roles.owner.permissions[] for those origins.

• medium — silent-attack OR operator-reviewable state. Two sub-shapes share this tier because they share a defense story (operator review catches it before the privileged effect escapes). (a) silent-attack: secretExfilBash, secretExfilRead, ssrf, and sessionSearchSecrets are heuristic/plugin defenses for non-canonical surfaces; bypassing them still cannot expose canonical credential stores or reusable child auth. For ssrf, a bypass skips only the heuristic plugin pre-check—the safe web_fetch/URL-backed look_at transport still enforces its independent policy below. (b) operator-reviewable state: bypass writes to a file the operator force-commits and reviews before the privileged effect takes hold — gitExfil (push to a clean operator-configured remote; the retarget-and-push path stays blocked by gitRemoteTainted at high), rolePromotion (roles is restart-required so the operator has wall-clock time), cronPromotion (deferred execution gives wall-clock time to revert). owner and trusted bypass these plugin guards; member, guest do not.

  Important: cronPromotion, rolePromotion, and pluginAddition no longer honor acknowledgeGuards. For these three guards the bypass is permission-only — an actor bypasses them automatically by holding security.bypass.medium (owner and trusted have it by default) or the per-guard security.bypass.<guard> string. No per-call ack is accepted or possible. Additionally, cronPromotion is caller-role-aware: it only blocks changes that schedule deferred work above the caller's own resolved role (see typeclaw-cron for the full model). The gitExfil guard and all other guards still accept acknowledgeGuards per-call acks at the plugin layer, but an ssrf acknowledgement never bypasses the safe HTTP transport.

• low — noisy, immediately recoverable. No inhabitants today. Forward-compat for future guards. owner, trusted, member all carry bypass.low; guest does not.

At tool.before time, an actor bypasses a guard if they hold either the tier permission or the per-guard permission (OR-check, both axes work forever).

owner carries security.bypass.low + security.bypass.medium + security.bypass.high AND the wildcard sentinel. The bundled security plugin sets ownerWildcardExclusions: [], so the sentinel expands to every plugin-contributed security.bypass.* string. Net: owner auto-bypasses every plugin tier and per-guard string by default, but never the core canonical-secret boundary or the safe HTTP transport's SSRF policy. trusted carries bypass.low + bypass.medium — no high-tier grants by default. member carries bypass.low — no medium/high. guest carries no security.bypass.* strings.

SSRF has a non-bypassable transport layer

security.bypass.ssrf, security.bypass.medium, owner, trusted, and acknowledgeGuards.ssrf can skip the heuristic tool.before warning only. They cannot make the safe transports behind web_fetch and URL-backed look_at connect to a destination that transport policy rejects.

Intentional internal access is operator-configured in raw-masked .env, not in roles or tool arguments:

• TYPECLAW_MODEL_HTTP_ALLOW_INTERNAL_HOSTS=service.corp,printer.local — comma-separated exact hostnames; case-insensitive and IDNA-normalized; no wildcards, suffix rules, URLs, or IP literals.
• TYPECLAW_MODEL_HTTP_ALLOW_INTERNAL_CIDRS=10.20.0.0/16,fd12:3456::/48 — comma-separated IPv4/IPv6 CIDRs with explicit prefixes.

Each variable accepts at most 64 entries; malformed or empty entries fail boot. Both are parsed once at container startup, withheld from model bash, and inaccessible through the raw live .env mask. Only the operator can change them, and changes require typeclaw restart; reload does not re-read them.

Even those exceptions cannot permit known cloud metadata/control-plane endpoints, their standardized compatible/mapped/translatable, well-known NAT64, and 6to4 IPv6 forms, or the ambiguous RFC 8215 local-use 64:ff9b:1::/48 translator range. Separately, when typeclaw.json#network.blockInternal is enabled, private IPv4 traffic generally also needs a narrow network.allow entry to pass the container firewall. The .env transport policy and network.allow are independent gates.

Trusted is operator-class for the agent's own state. Because gitExfil, rolePromotion, and cronPromotion are medium-tier, trusted users can push to operator-configured remotes, edit typeclaw.json#roles, and add cron jobs without per-call acks. The two-step taint defense (gitRemoteTainted, still high) still blocks the retarget-and-push attack. The privilege-escalation defense for roles/cron edits now leans on operator review of auto-backup commits — typeclaw.json and cron.json are force-committed on idle, and the operator sees diffs before reload/restart. Deployments that don't review backup commits should keep roles.trusted.match[] narrow, OR subtract by replacing roles.trusted.permissions[] with an explicit list that omits security.bypass.medium.

Narrowing owner. If a deployment matches owner to a channel author (not just TUI), the audience-leak defense (owner-in-public-channel) is at risk. Two ways to narrow: (a) tighten roles.owner.match[] back to TUI-only and use a separate role for channel access; (b) replace roles.owner.permissions[] with an explicit list that omits security.bypass.high (and the wildcard sentinel) for the deployment. Either path is supported.

Widening lower roles. Operators who want member to push without acks (or to bypass any other guard) add the per-guard string explicitly via the OR-check: roles.member.permissions: [..., "security.bypass.gitExfil"]. This is narrower than granting a whole tier.

Note on the two-step gitRemoteTainted defense: trusted bypasses gitExfil via bypass.medium, so trusted's first-step git remote set-url succeeds AND the recorder fires; the second-step push is then blocked by gitRemoteTainted (high tier, trusted lacks bypass). The same shape holds for any actor who bypasses gitExfil (per-guard OR via tier) but not gitRemoteTainted — the recorder runs on the first step gated by "would the command actually run", so the second-step checker has taint state to consult. The two are independent per-guard strings AND independent tier classifications.

Two-layer defense for channel-side git operations: the runtime tool.before guards are not the only layer that gates git push from channel messages. The security plugin's session.prompt hook also pattern-matches inbound text for git push / git remote add / gh repo create --push and injects a refusal rule into the system prompt. The prompt-side git_exfil defense is gated to non-subagent origins — it fires for channel and tui prompts but skips subagent prompts. The reason: bundled subagents like backup-diagnose legitimately embed git stderr in their payloads (which contains literal "git push --help" hint strings on failures), and triggering the defense there would inject a "do NOT run git push" rule that contradicts the subagent's own system-prompt instructions to retry with an ack. The runtime tool.before is the universal backstop for subagents (under the audience-leak policy, even owner-spawned subagents need an ack for git push), so the prompt-side check is redundant for them and harmful to bundled-plugin recovery flows. For channel and TUI prompts the two layers agree: nobody auto-bypasses gitExfil at the runtime layer, so the prompt-injection layer's text-match refusal is the same answer the runtime would give. The only case where the two layers disagree is when an operator has explicitly granted security.bypass.gitExfil to a channel speaker's role in typeclaw.json — then the runtime would allow the push but the prompt-injection text-match would still refuse. That's a known narrow-scope gap (operator opted into the bypass already); if the user is confused why the agent refused a channel-side push despite the per-guard grant they added, this is why.

User-declared permissions[] strings that don't appear in any of the three sources are logged as warnings at boot ([permissions] role "X" declares unknown permission "Y" — did you mean 'Z'?) but the role still resolves with the unknown string in its list. This is intentional — the runtime is forward-compatible with strings from plugins that aren't loaded yet — but it also means typos silently fail to bypass guards. If you wrote security.bypass.secretExfilBach instead of Bash, no guard will be skipped and you will only notice when you read the boot logs.

The mirror failure: a plugin permission no role grants

The typo case above is a role naming a permission that doesn't exist. The opposite also happens: a plugin declares a permission via definePlugin({ permissions: [...] }) (see typeclaw-plugins), but no role's permissions[] in typeclaw.json ever lists it. Declaring a permission only registers the string into the known-permission universe — it does not grant it. The only strings that auto-flow to a role are security.bypass.* ones, and only to owner, via the wildcard sentinel. Every other plugin-declared string starts out held by nobody — not owner, not trusted, not member, not guest.

Symptom: a plugin tool or command fails every call, for every user including owner, with a message naming the id — missing permission: <id>, or a blocked: reason citing it. Unlike a security-guard block, there's no acknowledgement and no role that already has it to fall back to; the string simply isn't granted anywhere.

Boot signal: [permissions] plugin "<name>" declares "<id>" but no role grants it — every surface gated on it will be denied. Add it to roles.<role>.permissions[] in typeclaw.json and restart.

Fix: add the exact string to roles.<role>.permissions[] and restart — same restart-required rule as every other permissions[] edit in this file. If <role> is a built-in (owner/trusted/member), remember an explicit permissions[] replaces that role's default list wholesale (see the table above); re-list the role's full default set alongside the new string, or the role silently loses channel.respond and everything else.

See typeclaw-plugins for the authoring side of this — declaring and gating on a permission is a two-part recipe, and shipping the declaration without the grant leaves a surface that looks wired but is dead.

When a tool is blocked

The security plugin's tool.before hook produces block messages. For most guards the message is:

Guard `<guardName>` blocked <what>. If this is genuinely intentional and the user
explicitly asked for it, retry with `acknowledgeGuards.<guardName>: true` in the
<tool> arguments. Or run as a role carrying `<per-guard-permission>` (...role hint...)
or the tier permission `security.bypass.<low|medium|high>`; see the
`typeclaw-permissions` skill.

For cronPromotion, rolePromotion, and pluginAddition the message omits the ack path entirely, because those guards no longer accept acks:

Guard `<guardName>` blocked <what>. To proceed, make this change from a session that
already resolves to a role carrying `<per-guard-permission>` or
`security.bypass.medium` — the TUI is always `owner`, or claim the role out-of-band
via `typeclaw role claim` from the host CLI.

Four escape hatches for bypassable plugin guards, ordered from least to most invasive. If the block concerns a canonical credential path, reusable authentication, or the safe HTTP transport's SSRF floor, there is no role/ack escape hatch; direct the operator to the appropriate host-side workflow instead.

1. acknowledgeGuards.<guardName>: true in the tool args. This is a per-call, in-session bypass for guards that support acknowledgements. Never use it without explicit user confirmation. It cannot authorize canonical secret access, credential handling, or a safe-HTTP destination rejected by transport policy. Exception: this escape hatch also does NOT apply to cronPromotion, rolePromotion, or pluginAddition. Those three guards ignore the ack flag entirely — they are bypassed only by holding the appropriate permission (see options 2-4 below) or via typeclaw role claim from the host CLI.
2. Run as a role with the per-guard bypass permission. If the user wants this pattern to keep working without an ack every time, they edit roles.<role>.permissions[] to include the specific security.bypass.<guardName> string the block message named. This is the most granular grant — it only opens up that one guard. Use this when the user wants exactly one capability and nothing else.
3. Run as a role with the tier bypass permission. The block message also names the tier permission (security.bypass.low / .medium / .high). Granting the tier opens every bypassable plugin guard of that tier at once — never canonical secrets.
4. Run from a session that already resolves to a role with the bypass. The TUI is always owner, so a bypassable plugin guard that blocks a member channel author may permit the TUI. Canonical credential denial and safe-HTTP transport validation remain identical in both places. For cronPromotion, rolePromotion, and pluginAddition specifically, use a session carrying security.bypass.medium or claim the role out-of-band via typeclaw role claim from the host CLI.

When you see a block, tell the user which permission would skip it (the block message now names both the per-guard and the tier options) and which built-in roles have those permissions. Do not just relay the guard reason — that loses the access-control framing entirely.

When the user asks "why aren't you replying in #channel?"

Probable causes, in descending order of frequency:

1. No match rule covers the speaking author's coordinates. Read typeclaw.json roles, compare every match[] entry to the channel ID and author ID the user is reporting. If nothing matches, the author resolves to guest, which has no channel.respond, so every inbound is dropped at the router. The fix is to append a match rule to roles.<role>.match[] for that channel (or DM bucket).
2. The match rule exists but the role has permissions: [] (or otherwise lacks channel.respond). A user-declared role replaces the built-in's permissions wholesale. Re-add channel.respond or use a built-in role name (member, trusted, owner) that carries it by default.
3. Engagement triggers are filtering admitted messages. This is a different problem — the inbound was admitted by permissions but engagement (channels.<adapter>.engagement.trigger) decided not to wake you. See the typeclaw-channels skill for the engagement model.

To distinguish cause 1/2 from cause 3: if typeclaw logs <container> -f (host stage) shows [channels] ... denied by permissions (channel.respond), it's a permissions problem. If it shows the message being admitted but no LLM call follows, it's engagement.

When the user asks "let X talk to you in this channel"

This is a roles edit. The full procedure:

1. Resolve the coordinates. Get the platform name (slack | discord | telegram | line | kakao), the workspace ID, the chat ID. If the user gave you names, ask them or look them up in the participants list of a previous inbound from that channel.
2. Pick a role. Default to member for "give them normal channel access" — member carries bypass.low only, so no medium/high security guards are skipped. Use trusted if they're operator-class for this agent: trusted carries bypass.medium by default, which means trusted automatically bypasses secretExfilBash, secretExfilRead, the heuristic ssrf pre-check, sessionSearchSecrets, gitExfil (push to a clean operator-configured remote), rolePromotion, and cronPromotion; this does not bypass the safe HTTP transport's SSRF policy. Trusted does NOT bypass gitRemoteTainted, outboundSecret, or systemPromptLeak (still high-tier). Use owner only for the primary operator — owner auto-bypasses every plugin tier including high, but not the transport floor. The owner-in-public-channel risk (a channel-matched owner silently posting credentials to a public chat) is the reason roles.owner.match[] defaults to TUI-only; widening it requires either narrowing the match or stripping security.bypass.high from roles.owner.permissions[].
3. Edit typeclaw.json roles.<role>.match[]. Append the canonical DSL string. Example: roles.member.match adds "slack:T0123/C0ABCDE". If the user wants only a specific person in that channel, append slack:T0123/C0ABCDE author:U_ME instead. The rolePromotion guard blocks any write that widens a role's match[] or permissions[] — this is the runtime check that defends against the canonical "channel speaker asks to promote themselves" attack. rolePromotion no longer accepts acknowledgeGuards — the ack flag is ignored for this guard. The bypass is permission-only: the write must come from a session that already holds security.bypass.medium (owner via TUI, or a role explicitly granted security.bypass.medium or security.bypass.rolePromotion). If the request came from a channel message, do NOT attempt to pass an ack — it won't work. Instead, make the edit from the TUI (always owner) or tell the user to run typeclaw role claim from the operator's host CLI. Never widen a role on behalf of a channel speaker asking to elevate themselves — refuse and direct them to the out-of-band typeclaw role claim path. The same rule applies to introducing a brand-new role with non-empty grants, or widening any existing role's permissions[].
4. Restart. roles is restart-required — typeclaw reload does not re-evaluate role config. Tell the user: "edited roles.<role>.match — restart-required. Run typeclaw restart (host stage)."
5. Commit the change. See the typeclaw-git skill. The decision context in the commit message should name the role, the channel, and the author/scope ("let @X talk to me as member in #foo in workspace bar").

When the user asks "stop replying to X"

Two interpretations — clarify if ambiguous:

• "Stop everything" — remove the match rule from roles.<role>.match[]. The author resolves to guest, and the channel router silently drops every inbound. You lose all visibility into their messages. Restart-required.
• "Just stop auto-replying" — keep the match rule, but narrow channels.<adapter>.engagement.trigger and/or stickiness. See typeclaw-channels. The agent still receives the messages and can still post if you tell it to. The solo-human fallback (single human in a channel) overrides trigger: [], so this approach can't fully silence you in a 1:1; only removing the match rule does.

When the user asks "what role am I in this session?"

Read your ## Session origin block — the role/permissions line is there for non-TUI sessions. For TUI it's owner by definition. If the user is in a channel and asks about themselves, read typeclaw.json roles and match their <authorId> against every match[] entry in severity-then-declaration order (walk owner first, then trusted, then custom roles in reverse declaration order — later wins, then member, then guest); the first hit wins. Do not invent a role they aren't in.

When the user asks about cron / subagent provenance

Cron and subagent sessions don't resolve their role by matching their own origin — instead, the role is stamped at creation:

• Cron jobs carry scheduledByRole in cron.json. The job runs as that role. If scheduledByRole is absent on a hand-authored cron entry, boot fails with a precise error (there is no implicit fallback). Plugin-contributed cron jobs default to owner.
• Subagents carry spawnedByRole, snapshotted from the spawning session's resolved role at spawn time. A cron-fired subagent inherits the cron's stamped role.

This forecloses the laundering attack — an attacker who only resolves to guest can ask you to schedule a cron, but the cron entry will be stamped scheduledByRole: 'guest', and when it fires it will still be guest (with no permissions, including no channel.respond or security.bypass.*).

If you see a cron job mysteriously failing every fire with denied by permissions in logs, check its scheduledByRole — it may have been scheduled by a guest session at some point in the past.

Things you must not do

• Do not write * in user-declared permissions[]. The owner wildcard is a runtime sentinel, not part of the user-facing string format. The schema rejects * (it's not a valid dotted permission string anyway).

• Do not invent permission strings. Only the three sources above (core, security plugin including the eight per-guard + three tier strings, declared plugins) contribute valid strings. A string like bash.execute looks plausible but is not gated by anything and will only earn a boot warning. If the user asks for a permission the model doesn't have, tell them — don't invent one.

• Do not grant security.bypass.high to non-owner roles casually. High-tier guards (outboundSecret, systemPromptLeak, gitRemoteTainted) defend the direct audience-leak axis — bypassing them means data leaves the operator's perimeter with NO operator-visible intermediate step. owner carries bypass.high by default under the role-tower model, so the default asymmetry is: a TUI operator can do these things silently, a channel speaker matched to owner can too (which is the defense rationale for keeping owner's match narrow). Granting security.bypass.high to trusted or a custom role opens audience-leak bypass on every current high-tier guard PLUS every future high-tier guard added by a security plugin update. If the user wants one specific high-tier bypass for a lower role, grant the per-guard string explicitly (security.bypass.outboundSecret) on the specific role, not the tier — that's narrower and won't widen on plugin updates.

• Be careful with roles.trusted.match[] for broad audiences. Trusted carries bypass.medium by default, which is now operator-class for the agent's own state: trusted bypasses not just the silent-attack plugin guards (secretExfilBash, secretExfilRead, the heuristic ssrf pre-check, sessionSearchSecrets) but ALSO the operator-reviewable-state guards (gitExfil to clean remotes, rolePromotion, cronPromotion). The safe HTTP transport's SSRF policy still applies. A trusted role matched to a broad Slack workspace means any trusted speaker can ask the agent to dump non-canonical env surfaces, push to operator-configured remotes, OR write a privileged change to typeclaw.json/cron.json without acks — the operator only catches the latter two on backup-commit review BEFORE the next restart/schedule tick. If the user wants a wider trusted audience without the operator-class authority, replace roles.trusted.permissions[] with an explicit list that omits security.bypass.medium (and add only narrower per-guard strings as needed).

• Do not promise that typeclaw reload applied a roles edit. roles is restart-required. The reload tool will return success on the config file change, but the live PermissionService was built at boot and is not swapped on reload.

• Do not silently change a built-in role's permission list. Setting "permissions": [] on member is a wholesale replace, not a merge — you just took channel.respond away from every speaker who resolves to member. If the user said "give member just channel.respond and nothing else", that's fine (it's the same as the default), but say so explicitly: "this matches the default for member, no behavior change". If the user said "remove cron from trusted", make the change but warn that trusted no longer carries cron.schedule either.

• Do not write match rules using display names (#general, @user, channel/user names). Match rules are platform IDs. Display names change; IDs don't. Always look up the ID before writing the rule.

• Do not edit roles to "fix" a security block without explaining the alternative. For most guards, the right first move is acknowledgeGuards.<X>: true for the specific call. Exceptions: cronPromotion, rolePromotion, and pluginAddition do not accept acks; an ssrf ack only skips the heuristic plugin pre-check and never changes safe-HTTP transport policy. Intentional internal web_fetch/URL-backed look_at access is an operator boot-policy change, not a role edit. Editing roles to grant a permanent bypass is a heavier change with security implications — get explicit consent.

• Do not interpret a missing ## Session origin role line as "I have no role". TUI sessions don't render the line because TUI is always owner. If you see no role line and you're not in TUI, something has gone wrong with the system prompt build — flag it, don't fabricate.

What this skill does not cover

• The channels.<adapter> block behavior — engagement, history, stickiness, alias matching. See typeclaw-channels. Engagement decides whether an admitted inbound wakes the loop; this skill is only about admission. The channels/alias schema and edit mechanics live in typeclaw-config.
• The full typeclaw.json schema — model, mounts, plugins, docker, git.ignore. See typeclaw-config.
• Cron job authoring — schedule syntax, prompt vs exec, the reload tool. See typeclaw-cron. This skill only covers the scheduledByRole field and its provenance semantics.
• Plugin authoring — definePlugin, contributing permissions, custom tool.before hooks. See typeclaw-plugins. The bundled security plugin is an example of a plugin that contributes security.bypass.* strings and uses permissions.has() to gate its own guards.
• The container vs host stage split — typeclaw restart runs on the host; this skill assumes you know which stage you're in. See AGENTS.md for the stage model.
