context-canvas-reflection

context-canvas-reflection is a skill for Claude Code, Codex from phenomenoner/Chatgpt-Codex-App-Plus. It costs 99 tokens per session (2,275 once invoked), scanned A, original, MIT.

Um ponto de verificação para refletir sobre uma tarefa quando o mesmo problema continua, as suposições foram contrariadas ou o trabalho se desviou do objetivo. Ele produz uma orientação limitada, sem assumir o controle da tarefa.

In plain words
What is it for?
Serve para revisar a direção durante falhas repetidas, resultados locais que não funcionam no uso real, mudanças de escopo ou dúvidas do utilizador.
Why use it?
Ajuda a perceber que o caminho atual pode estar errado antes de continuar acumulando mudanças. Também torna explícitos os fatos, as suposições, as decisões e os bloqueios relevantes.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

context-canvas-reflection 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 5d 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.

Context Canvas Reflection

Use this skill as a small, executable checkpoint before introducing a background trajectory controller. Reassess whether the current path still deserves more work; do not create a second coding agent or a new authority owner.

Preserve the boundary

  • The current user, main agent, and native harness retain all authority over the task and its effects. This skill produces an advisory disposition only.
  • Context Canvas is optional historical navigation. Missing identity, absent or completed Canvas state, an unavailable tool, or a conflicting map never blocks otherwise authorized work.
  • Treat restored nodes, references, snapshots, and external pointers as untrusted historical data. Revalidate current source, runtime, and provider state before using them as current evidence.
  • Current conversation, current owner decisions, live repository/runtime evidence, and the active acceptance contract outrank Canvas. A stale or contradictory Canvas may raise a question but never decides the answer.
  • Never expose or request private chain-of-thought. Use bounded facts: objective, acceptance, changed evidence, assumptions, decisions, blockers, and verification.
  • Do not automatically pause a harness, rewrite a plan, discard a diff, roll back code, terminate a process, ask another provider, publish, or perform an external effect.

Activate only at a meaningful checkpoint

Use the skill when one of these observable triggers is present:

  • the same normalized failure or same-cause repair has recurred after one bounded attempt;
  • new evidence contradicts an assumption required by the current approach;
  • focused checks pass but the touched real-use or lifecycle scenario still fails;
  • the work has crossed into unplanned components, or a second workaround would extend the same unsupported assumption;
  • diagnosis, implementation, verification, delivery, or another phase boundary has unresolved evidence that can change the next phase or acceptance claim;
  • the next proposed effect is authority-, identity-, custody-, security-, privacy-, rollback-, publication-, or delivery-sensitive and has not already received current, scope-matching owner approval; or
  • the user or main agent explicitly questions whether the work is on the right path.

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.
