-Les skills agentiques associent désormais leur `SKILL.md` portable à un fichier -`skill.yaml` contrôlé par le client. Le manifeste indique les bundles métier, -les outils requis, les observations nécessaires à un rapport complet, l'objectif -et les limites d'appels. Les dossiers qui contiennent ces deux fichiers sont -découverts automatiquement au démarrage du client. `identify-user` demande -`recon.identity`, qui n'accorde que `whoami`. La liste résolue est enregistrée -dans le run pour que sa reprise conserve les mêmes permissions après une mise -à jour du catalogue. - -Le catalogue [`bundles.py`](../C2Client/C2Client/assistant_agent/capabilities/bundles.py) -recense les capacités par objectif : `recon.identity`, `recon.host`, `exec`, `pivot`, `file_ops`, -`payload_delivery`, `credentials` et `session_management`. Il inclut les -commandes beacon et les opérations TeamServer ou locales destinées aux futurs -adaptateurs, notamment SOCKS, hébergement d'artifact et génération de dropper. -Le résolveur ne transmet à agent-core que les outils réellement enregistrés ; -un outil requis absent fait échouer le démarrage du skill. Le catalogue et ses -tests résident dans `assistant_agent/capabilities`, car il est partagé par les -skills et la conversation. Le catalogue des définitions de skills reste dans -`assistant_agent/skills`. - -`recon-host` est le premier skill agentique multi outils. Il associe -`recon.identity` et `recon.host`, exige `whoami`, `ipConfig` et -`listC2Listeners`, puis laisse le LLM choisir ses appels dans la limite de dix -outils. Le client fixe la session, valide chaque argument, charge un module -manquant, crée un job V2 stable avant l'envoi de chaque commande et attend son -résultat. Le run conserve la liste des outils, leurs spécifications, les jobs, -les octets exacts et les observations TeamServer. Le curseur V2 et l'identifiant -de l'événement terminal de chaque job sont enregistrés, y compris lorsque le -polling `GetJobExecution` constate le résultat avant le flux. Après redémarrage, -le client relit les événements du job en cours depuis le curseur, vérifie son -état puis reprend les choix du LLM sans renvoyer une commande déjà acceptée. -Le rapport cite les `job_id` et les -`observation_id` réellement observés ; une citation inventée invalide l'analyse. -Un rapport sans résultat réussi de `whoami`, `ipConfig` et `listC2Listeners` -reste partiel, même si le modèle conclut autrement. - -Sur Windows et Linux, `recon.host` expose aussi `hostContext` pour collecter le -nom d'hôte, la version de l'OS et du noyau, la configuration du résolveur et les routes IPv4. -Le module `netstat` restitue les adresses dans l'ordre réseau, nomme les états -et associe les sockets aux processus lorsque `/proc//fd` est accessible. -L'absence d'association reste explicite (`Owner:unknown`). `hostContext` est -facultatif si le module n'est pas chargé ; le skill signale les observations non -collectées plutôt que de les inventer. - -Les adaptateurs `listC2Listeners` et `listC2Artifacts` sont des lectures -TeamServer utilisables par la conversation et les skills. `hostArtifact` et -`socksControl` sont des opérations terminal typées utilisables par la -conversation ; elles ne donnent pas accès à une commande terminal libre. Les -opérations terminal à effet de bord ne sont pas encore enregistrées dans les -runs de skills, car leur exécution ne possède pas d'identifiant de job V2 pour -récupérer avec certitude une réponse perdue. La génération de dropper reste -liée à son parcours local et demande encore un adaptateur sans widget Qt. Le -plan fixe `inventory_local` et le skill `identify-user` restent disponibles. - -## Premier skill agentique : identify-user - -Le dossier `C2Client/C2Client/assistant_agent/skills/identify-user/` contient un -`SKILL.md` au format [Agent Skills](https://agentskills.io/specification) : -frontmatter YAML `name` et `description`, puis instructions Markdown. Le client -charge ces instructions dans un `StructuredTaskSpec` d'agent-core. Le modèle -choisit d'appeler le tool `whoami` ; le client fixe la session choisie par -l'opérateur et n'expose aucun autre tool à ce run. - -L'appel au tool crée un job V2 avec un identifiant stable et retourne `pending` -à agent-core. Le client attend le résultat, y compris après redémarrage, puis -appelle `resume_pending_tool` avec la sortie observée. Si `whoami` nécessite un -module, son chargement est un prérequis technique suivi par le client ; le -modèle reçoit la sortie de `whoami`, jamais le résultat du chargement comme -preuve d'identité. **No result** peut terminer l'attente avec un rapport -partiel. Le rapport et les octets exacts des jobs restent dans le journal local. - -Le format `SKILL.md` apporte les instructions portables. La permission effective -du tool et le périmètre de session sont imposés par le code du client ; les -instructions Markdown ne peuvent pas les élargir. Le premier skill reste -volontairement limité à un seul appel. `inventory_local` ci-dessous conserve son -ancien plan fixe pour les runs déjà enregistrés. - -La liste des tâches indique **Agent** pour `identify-user` et **Fixed** pour -`inventory_local`. Le bouton **?** donne la description et la méthode de la -tâche au survol ou au clic. Les runs sont dans un menu déroulant ; le rapport -conserve sa position de lecture lors des rafraîchissements. L'entrée **Any -session** est visible pour préparer les futurs skills multi sessions, mais -reste désactivée : les deux skills présents exigent une session précise. - -## Inventaire local à plan fixe - -La vue **Data AI → Tasks** propose directement les sessions actives du -TeamServer. Elle sélectionne automatiquement la seule session disponible ; -sinon, choisir une session dans la liste puis cliquer sur **Start**. Le bouton -**Refresh** recharge les sessions sans ouvrir de console. Le skill -`inventory_local`, versionné dans le client, exécute `whoami` puis -`ipConfig`. Si un module manque, le client exécute d'abord `loadModule` et -attend sa réponse ; ce chargement possède son propre job et reprend après -redémarrage du client. Un module déjà en cours de chargement est suivi par son -identifiant existant, sans nouvelle soumission. La réponse précise -`Module already loaded` du beacon valide également ce prérequis : le job de -chargement conserve son état brut d'échec dans les preuves, puis la commande -demandée est envoyée. Les autres échecs de chargement restent des échecs. -Le LLM interprète les résultats observés dans un rapport structuré en anglais ; -il ne choisit ni ne modifie les commandes du plan. - -La vue Tasks présente le rapport sous forme de phrases et garde les identifiants -de jobs, états bruts et sorties dans **Show execution details**. Le stockage -conserve le rapport structuré et les preuves exactes pour la reprise et l'audit. - -La conversation applique la même précondition : un appel à un outil de module -charge automatiquement ce module s'il manque, attend le résultat du chargement, -puis envoie la commande demandée. `outcome_unknown` maintient l'attente jusqu'à -un résultat tardif ou `/stop`. Le chargement réussi seul n'est jamais présenté -comme le résultat de la commande demandée. Une réponse `Module already loaded` -enchaîne également sur la commande demandée. - -## Propriété et reprise - -Le client possède l'ordonnanceur et les fichiers de tâche dans -`C2Client/C2Client/logs/assistant_sessions/skills/runs/`. Le TeamServer possède -les jobs, leurs résultats et leurs événements V2 dans SQLite. Chaque étape a -un `job_id` stable. Après un redémarrage du client, les tâches inachevées sont -relues, les jobs sont interrogés avec `GetJobExecution`, puis le suivi des -événements reprend. Une soumission dont la réponse s'est perdue est vérifiée -par son `job_id` avant d'être retentée avec **le même identifiant**. - -Une commande peut rester en attente sans délai automatique, y compris lorsque -le serveur indique `outcome_unknown`. L'opérateur peut déclarer **No result** -avec une raison ; l'étape devient incertaine et le rapport est partiel. -**Mark failed** clôt la tâche entière. Aucune de ces actions n'annule une -commande déjà envoyée au beacon. Un résultat tardif est enregistré comme état -tardif et ne réécrit pas un rapport déjà terminé. - -Les sorties exactes de jobs réussis sont encodées en base64 dans le journal de -tâche. Le rapport donne un aperçu de 16 000 octets, une taille et un SHA-256. -Les résultats de `loadModule` restent dans les preuves mais ne sont pas cités -comme des observations de l'inventaire. -Une sortie rejetée par la limite du serveur apparaît comme échec du job ; elle -n'est pas présentée comme preuve complète. Si le LLM échoue, les preuves restent -consultables et le rapport est marqué partiel, avec analyse indisponible. - -Le rapport utilise `AgentRunService` et `StructuredTaskSpec` d'agent-core. -L'ordonnancement du plan fixe et la décision de clôture manuelle restent dans -le client. `agent-core` expose aussi la suspension et la reprise de tools -externes pour les tâches structurées, sur le même principe que la conversation, -sans changer les appels existants de PentestAssistant. - -## Installation et tests locaux +# Client-owned Agent Skills + +## Skill format and creation + +The client uses one skill format: a directory under +`C2Client/C2Client/assistant_agent/skills/` containing `SKILL.md` and `skill.yaml`. +Skills are shipped with the client source. Restart the client after adding or editing one. +The `SKILL.md` frontmatter supplies a lowercase hyphenated `name` matching the directory +and a description. Its Markdown body instructs the LLM. `skill.yaml` selects the C2 +capability bundles and sets the execution limits: + +```yaml +tool_bundles: [recon.identity, recon.host] +objective: Identify the selected session's user and network context. +required_tools: [whoami, ipConfig] +completion_tools: [whoami, ipConfig] +max_tool_calls: 10 +max_iterations: 16 +``` -Depuis la racine de C2TeamServer, après génération des bindings Python par le -build CMake (voir [build.md](build.md)) : +A required tool must be available for the selected session before the run starts. +Completion tools determine whether the final report can be considered complete. +The effective tool list is the intersection of the declared bundles, registered +adapters, and platform-compatible commands. A new skill can combine existing +bundles without adding Python code. A new C2 operation still needs a typed adapter. + +The Tasks panel shows the skill's description, bundles, and tools in its help popup. +The operator selects a live session and can enter **Additional task context** for +that run. The client snapshots this text, the skill instructions, TeamServer session +metadata, available tools, and command specifications. Session metadata and operator +context help guide the task; the report may cite only observed job or terminal +observation IDs as evidence. Changing a skill file does not change an existing run. + +## Execution and recovery + +Every skill uses agent-core's structured task executor. The LLM chooses tools within +the selected bundles. Beacon commands are bound to the selected session, validated, +and submitted as V2 jobs with stable IDs. If a module must be loaded first, its load +job is recorded separately; its output is not presented as the command result. +The client waits for each command and resumes from the stored event cursor after a +restart. An uncertain command is never resubmitted under a new ID. The operator may +mark **No result** to continue toward a partial report, or **Mark failed** to stop. +The client performs LLM work only while it is running; TeamServer may receive a +late beacon result while the client is closed. + +Skills can use the typed TeamServer tools already available to the conversation: +`listC2Listeners`, `listC2Artifacts`, `hostArtifact`, and `socksControl`, when their +bundles select them. `hostArtifact` and `socksControl` change TeamServer state. The +client records intent before invoking them. If the client is interrupted or loses +the terminal response and cannot establish the action's outcome, it records +`outcome_unknown`, avoids +automatic replay, and makes the report partial. The operator must inspect TeamServer +state before deciding whether to run the action again. These terminal actions do not +have V2 job IDs. Other terminal operations need typed adapters before a skill can call +them; the skill never receives a free-form terminal command tool. + +Reports contain a plain-English summary, findings cited by `source_id`, limitations, +and exact job output retained in the local run snapshot. Runs are stored under +`C2Client/C2Client/logs/assistant_sessions/skills/runs/`. Only the `agentic_skill` +run format is usable. Previous fixed-plan and identity-specific run files are not +listed or resumed. + +## Local build and tests + +From the C2TeamServer root, after CMake has generated the Python protocol bindings: ```bash -python3 -m venv C2Client/.venv -C2Client/.venv/bin/python -m pip install -e './C2Client[test]' -C2_PROTOCOL_PYTHON_ROOT="$PWD/build/generated/python_protocol" \ +C2_PROTOCOL_PYTHON_ROOT="$PWD/build-codex-scratch/generated/python_protocol" \ QT_QPA_PLATFORM=offscreen \ C2Client/.venv/bin/python -m pytest C2Client/tests -q -ctest --test-dir build -R '^(testsNetstat|testsHostContext|testsJobRuntimeE2E)$' \ +ctest --test-dir build-codex-scratch -R '^(testsNetstat|testsHostContext|testsJobRuntimeE2E)$' \ --output-on-failure --timeout 120 ``` -La dépendance `agent-core` est figée sur le commit qui fournit la suspension et -la reprise des tâches structurées.

Cette exécution se produit dans le processus client et dépasse sa fonction de présentation. Auditer l'origine, la version fixée, les droits du processus et les déclencheurs avant de considérer ces extensions comme fiables. 3. **Identité et état après redémarrage.** Les listeners et sessions sont tenus en mémoire dans le [service](../teamServer/teamServer/TeamServer.hpp) et le [cœur](../core/listener/Listener.hpp), tandis que les jobs disposent d'une persistance SQLite.

 - Tool calls must be deliberate, justified, and minimal.
+- Filter command, module, listener, and artifact inventories to the operator's current question. Show only relevant entries and explain why they matter; do not dump every capability by default.
+- Distinguish a file on the operator computer from a file on a beacon session. For a local file, use `uploadC2Artifact` before `upload`. For a remote file, use `download` to obtain its artifact ID, then `promoteC2Artifact` to create an operator-upload artifact, then `upload` with that new ID and the operator's exact destination path. Wait for each session command's result before reporting success. Never pass a downloaded artifact ID directly to `upload`.
+- For local payload generation, call `listLocalDroppers` when the installed module or shellcode generator is unknown, then `generateDropper` with explicit listeners. Report the returned execution command and any generation failure.
