Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00196 | $0.00656 |
| Opus 5 | $0.00098 | $0.00328 |
| Sonnet 5 | $0.00039 | $0.00131 |
| Haiku 4.5 | $0.00020 | $0.00066 |
Grade A, and why
role-task scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Session Role: task / build
Set this session's credo ROLE to task / build. This is a guiding default owner of
implementing GO items (items in 2_go/), INCLUDING commits and push where dogma permissions
allow. Only the task/build role commits and pushes, so a single index owner avoids a race on
.git/index.lock.
A role is orthogonal to the session mode (active | passive | autonomous): it can coexist with any mode. It is a guiding default, NOT a fixed constraint - on the user's wish you may still do mixed work, and an explicit user instruction always overrides the role.
When to use
- The user runs
/credo:role-task(the explicit, deterministic, guaranteed path). - The user assigns you this role in passing (best-effort, casual path) - for example "you are now the task/build agent", "you build the GO items", "take over the implementing", "act as the build agent", "du baust die GO-items", "uebernimm das Bauen".
Do NOT trigger on general discussion about roles, on explanations, or on questions such as "what does the task agent do" - those are not an assignment.
What it does
Write the persistent, per-session role marker. It is keyed by session_id under the
session-roles dir and re-injected on every prompt by role-inject.sh, so it survives context
compaction, new sessions and subagents (stored on disk, not in context):
"${CLAUDE_PLUGIN_ROOT}/hooks/role-set.sh" task
Confirm
Confirm in one short sentence, for example:
Role set to task/build - I am the default owner of building GO items (items in
2_go/), including commits and push where dogma permits. This is persistent and compact-safe (re-injected each turn); it is a guiding default you can override, and/credo:role-clearremoves it.
Do not do anything else - this skill only sets the role.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

role-task is a skill published in the GitHub repository Marcel-Bich/marcel-bich-claude-marketplace (13 stars, last pushed yesterday), licensed MIT. It adds 196 tokens to every session and 656 once invoked, about $0.0010 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
